How pandemics originate and evolve

History tells us pandemics have devastatingly interrupted civilizations. They killed millions of humans and brought forth misery and poverty, but never wiped out a civilisation. Epidemics and pandemics begin, escalate and wane or re-emerge. However, the causative agent rarely disappears; it opts for a less vicious coexistence. Smallpox is the only epidemically potent disease that has been eliminated absolutely – not via natural processes but by the intervention of human intelligence.

Life has been created by natural forces endowing an essence for it to reproduce and undergo change. We ourselves and the virus exist because of this, which also enables the virus to adapt itself to the environment, survive and expand causing the pandemic. In ancient times, humans had to await the consequences of the same natural forces to face a pandemic – those who remained fit and immune survived and reproduced.

Today, human intelligent intervention makes things more favourable to us than to the virus, and helps many who lack the natural immunity survive. The eventuality of the present pandemic will be determined by the effort we make to combat it.

 

How pandemics originate

Persian philosopher Ibn Sina was probably the first to conjecture that living entities in the human body caused diseases. Later, Louis Pasteur proved infections occurred when microscopic organisms entered the body and proliferated and those microbes could pass from one individual to another.

Microbes do not emerge spontaneously; nor do they arrive from the sky. They exist everywhere in the environment as creations of biological evolution. Humans, animals and plants harbour them. Microbes associated with a given species, often symbiotic, pose no danger to the host, whose immunity prevents their undue proliferation. They are selective; those present in one species would not easily move to a different type of host and get established. Nevertheless, the complexity of living things allow exceptions. Occasionally a pathogen or innocuous microbes concealed in animals or found in the environment can jump to a human causing diseases.

An illness acquired from an animal is referred to as a zoonotic disease or a zoonosis. Sometimes, the zoonosis turns out be contagious. Almost all calamitous epidemics and pandemics have arisen from accidental transfer of a bacteria or a virus from an animal species to humans and subsequent evolution- their origin is zoonotic. Ebola, Severe Acute Respiratory Syndrome, Middle East Respiratory Syndrome and COVID-19 are zoonotic diseases. The zoonotic infections such as plague, smallpox, measles and swine flu caused first magnitude pandemics in the past.

 

Ebola Virus Disease: near pandemic situation 2014-2016

A previously unknown sickness broke out near the Ebola River in Congo in 1976, killing almost 80% of persons who contracted it. The cause of the disease, subsequently named Ebola, was found to be a virus endemically associated with bats. Although the virus does no harm to the bats, when transferred to humans via contact during hunting, a fatal condition, similar to a flu occurs. The exposure to body fluids of the infected persons passes the disease to the community. The Ebola outbreak 2014-2016, spread across West Africa. Some cases were also reported in Europe and the United States.

 

Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS): The older cousins of COVID-19

Coronaviruses with crown like spikes on the surface exist everywhere. Until early 2000s, they were not considered a threat to humans. In 2002, a new contagious respiratory disease, SARS, emerged in China and spread rapidly to several other countries. International corporation; coordinated by WHO quickly elucidated the nature of the condition. The cause of the disease was identified to be a virus harboured by some bats, transferred to humans by palm civets. Handling civet cat meat in wet markets is believed to have caused the transmission of the pathogen to humans. The epidemic was effectively controlled by isolation of infected persons, use of masks, protective equipment, physical distancing and thermal sensing of passengers in airports. In July 2003, WHO declared SARS had been contained.

Another respiratory viral disease MERS first reported in Saudi Arabia in 2012 crossed continents due to air travel. The second major MERS outbreak occurred in South Korea in 2015. Compared to SARS, MERS is more virulent but less contagious, and spreads through close contacts of infected persons. The origin of MERS virus is zoonotic, bats being the primary source and camels the intermediate which transferred the pathogen to humans. The virus may have undergone genetic change in camels facilitating its adaptation to humans.

 

How pandemics evolve

Pandemics and epidemics begin when an infectious agent enters a community possessing no immunity to resist. A tragic example is measles epidemic in Fiji. In 1875, an Australian delegation carried the virus to the island whose natives were never exposed to the measles – a disease quite common in Asia and Europe. In a matter of months 30 percent of the population died!

Zoonotic viruses are particularly dangerous because humans are not exposed to them at the beginning. The absence of immunity allowed an epidemic in one locality to expand as a pandemic. Furthermore, when a virus originally found in an animal, genetically and associatively distant from humans, is harboured in an intermediate host closer to humans, some genetic intermingling could occur via processes referred to as recombination and re-assortment. This way, the virus acquires a foreignness needed to evade the human immune response and a kinship favourable for adaptation. Domesticated animals sometimes carry viruses originally derived from humans but genetically modified. A virus found in a wild animal co-infecting a domesticated one can copy genetic information from the latter producing a new kind of virus, adaptable to humans and also withstand host immunity.

The origin of the virus causing COVID-19 named SARS-Cov-2 has been traced to a bat species. The genetic make-up of SARS-Cov-2 tally nearly 95 percent with a virus found in so-called horseshoe bats. It is not conclusive whether the virus passed directly from a bat to humans or through an intermediate host. There exists no evidence to support the conspiracy theories that the virus leaked from a laboratory. Finding out how the virus came into being would shed light on how to control it effectively.

Once a pathogen enters a population devoid of immunity, the number of infected people begins to expand exponentially at a rate proportional to the population density reaching a peak. Thereafter, because of the decrease of susceptible persons owing to acquisition of immunity and deaths, the disease wanes.

Mathematical models predict above behaviour and point to the important concept of the effective reproduction number of a progressing epidemic. Effective reproduction number (RE) is the average number of people who acquire the infection from one infected individual at a given time. The idea of reproduction number was first introduced by the British Physician Ronald Ross, who took up mathematics to find a way to eradicate malaria. Ross showed that in order to control an epidemic RE needed to be kept below one. His suggestions for doing this paved the way for the eradication of malaria epidemics in Sri Lanka. In the initial phases of the COVID-19 pandemic in Wuhan, China RE has been in the range 3-5. Control measures such as physical distancing, wearing masks and isolation reduce RE, but the issue is reducing the number further to reach values below one. The mode of evolution of the COVID-19 pandemic is complicated by human migration by imposition and withdrawal of preventive measures.

Transmissibility and virulence

The virus is not after vengeance to be noxiously virulent and kill as many as possible; evolution in that direction renders no advantage because if a large majority of infected persons die, the virus will be deprived of hosts to feed on and reproduce.

The probability that someone will catch the infection from an infected person depends on the rate and quantity of the pathogen transmitted. A severe infection produces larger progeny of viruses; this has some advantage to the virus. Generally, pathogens compromise between transmissibility and virulence giving a higher weightage to the former. The transmissibility of COVID-19 is high because the infected shred the virus before symptoms fully develop. Contrastingly, in case of SARS; the infected release the pathogen at later stages when symptoms are readily identifiable enabling isolation; this is the main reason why SARS was contained and the COVID-19 transmission continues.

The virus aggressively attacking elderly and sparing younger could also be an advantage to the virus. Severely sick elderly patients release larger quantities of virus, infecting the younger who take care of them. The younger move about and infect others. The virus wants to procreate and exploits everything possible for that purpose!

Variations of the virus

Zoonotic viruses undergo major genetic changes via recombination or re-assortment and adapt to human system. Mutations enable them to fine-tune the traits favourable for adaptation by small genetic adjustments. When viruses replicate, their genetic code is sometimes copied erroneously, resulting in random variations. The process is analogous to typographical errors you make when you retype your essay. Even if you retype thousand times, you would not expect to find an improved version of the essay as result of random typographical errors. However, when a virus replicate trillions of times; a more adaptable one may originate and replicate endlessly – these are new strains of the virus. Recently, more contagious strains have been found to proliferate in the UK, Brazil and South Africa. The British Prime Minister announced that the variant identified in his country seemed to be more virulent.

Convergent evolution of strains

The three strains of the virus (United Kingdom, Brazil and South Africa) seemed to have evolved independently. Yet, all the three variants have undergone similar changes in the spike protein, enabling the virus to attach to host cells more strongly; this is essential for efficient spreading. The qualities acquired indicate that mutations have got selected for the definite purpose of convergence to the same cause – to spread the disease fast.

Convergent evolution is quite common in nature. A prototypical example is the near identical streamlined body shapes of the shark and the dolphin. Shark is classified as a primitive fish, whereas the dolphin has been an evolutionarily modern four-legged mammal that lived on land adapted to the ocean. Both shark and dolphin independently evolved towards the optimum hydrodynamic body features to be able to swim fast.

Future of the Present Pandemic and Future Pandemics

It is too early to determine the degree of effectiveness of existing vaccines to new and emerging strains. Fortunately, some vaccines can be easily reprogrammed to provide immunity to new strains. The world will soon acquire the arsenal of weapons needed to fight it. Efficacious vaccines have been demonstrated, and many are in the pipeline. Antiviral drug research progresses although to date there exist no cure for COVID-19. The virtues of physical distancing, wearing masks, contact tracing and isolation are gaining acceptance. Hopefully wide vaccinations programmes and strict adherence to preventive measures will help subdue the pandemic; a concerted effort is imperative. As pointed out in the editorial The Island editorial of 21st January 2021 ensuring equitable access to vaccines is an urgency. This the factor determining what lies ahead and how the pandemic will halt.

Doing the needful forthwith is prudent because given sufficient time the virus might mutate in response to a single political decision implemented somewhere, irrespective of the geographical location.

The other issue would be the emergence of new pandemics in the future – most likely those of zoonotic origin. During the past two decades many such diseases have surfaced. Excessive interference with environment; clearing forests, maintaining millions of farm animals in unnatural conditions and climate change resulting from burning fossil fuels probably contribute this dangerous trend.

When humankind turns cruel to animals, destroy flora and engender environment, the return could be a pandemic!

The 22nd Amendment, constitutional recovery and illiberal slippage

Published

on

by Dinesha Samararatne
Professor, Dept. of Public & International Law, Faculty of Law of the University of Colombo
 and was an independent member of Sri Lanka’s Constitutional Council (Jan. 2023 to Jan. 2026).

Sri Lanka’s political transition in 2024 was widely regarded as restoration of democracy, a reversal of authoritarian rule and an opportunity for constitutional recovery. The 22nd Amendment is the first constitutional amendment since this turning point. It 1) extends the age of retirement of the judges of the superior courts by two years, 2) expands the number of judges in the Court of Appeal by 4, and 3) introduces a cap of 6 years on the term of a Chief Justice. The expansion of the Court of Appeal is meant to facilitate the Court sitting outside of Colombo.

This Amendment is a stress-test on Sri Lanka’s democratic restoration as well as constitutional recovery. This Bill was published in the Gazette along with a proposed amendment to the Judicature Act of 1978, which sought to extend the age of retirement for the lower judiciary and to increase the number of judges of the High Court by 10. The enactment of the Amendment coincides with the completion of two years of this Government. Here, I offer a brief assessment of some of the key policy and constitutional issues involved.

Democratic Transition and Constitutional Recovery

There were many signs of a new lease of political life in Sri Lanka following the presidential election in 2024. Many politicians (of a certain kind) who sensed the change chose to not even contest the parliamentary elections. An Inspector General of Police (whose appointment itself was, at the time, under challenge) was impeached, and the political discourse seems to shift towards more democracy, transparency and accountability. The vigilance of the engaged citizen (as opposed to the mere voter) was evident in the pushback which led to the resignation of a Speaker as well as a Minister.

Some may say that these changes were too little and too late. After all, the Online Safety Act and the Prevention of Terrorism Act remain on our law books and we are still governed by an Executive President. Some others may argue that these are signs of a significant paradigm shift that is underway. Since 2025, the number of investigations, prosecutions and convictions related to bribery and corruption has been unprecedented, the President’s Fund is being accessed by people on the basis of financial need and there seems to be a change in the political culture. Whether these changes may be consolidated, it is too early to tell.

Policy and the 22nd Amendment

The 22nd Amendment to our Constitution suggests that political tactics familiar to the old order of things (to the extent that that order is in our past), are re-emerging. A proposal for a constitutional amendment which is piece-meal (with no convincing explanation for its selectivity), is published in the gazette without public consultation – not even consultations with relevant professional bodies – and is enacted without bi-partisan consensus. A recent example of a similar approach is the expansion of the number of judges in the Supreme Court and Court of Appeal by way of amendments at the Committee Stage of the 20th Amendment in 2020, with no transparency or consultation and with political justification post-Amendment. Many questions arise and remain unanswered. Among the many issues that plague our courts, on what basis were these issues prioritised for reform? As in the past, the process has been opaque and rushed. In turn this has led to polarised debates which carry the risk of compromising the confidence in the Government.

Laws delays, one of the stated concerns that the 22nd Amendment seeks to address, is at crisis levels in Sri Lanka. It is certainly a concern for citizens but it is a concern along with the extremely weak mechanism for legal aid, the lack of accessibility of court procedures and the difficulties we face for instance at a police station. We have a right to know why amidst all these serious and ubiquitous issues, the government prioritised constitutional reform in this selective manner. Constitutional reform must demonstrate a compelling link between the aspirations of the people for democracy, for human dignity and the flourishing of life. If the plight or aspirations of people are weaponised by political forces or elected representatives, we carry the burden of calling that out.

My own view is that a review of the age of retirement of judges is long overdue, but whether and how it ought to apply to sitting judges, carries the real or perceived risk of undermining the independence of the judiciary. Moreover, that is certainly not the only reform that is long overdue. The minimum criteria for the appointment of a judge to our superior courts is governed by convention (sometimes in the breach), not by law. In fact, the law does not lay down any criteria for appointment to our superior courts despite the Court’s assertion in its Determination on the 22nd Amendment bill that judges are appointed on merit, ‘competence and ability to work hard’ (p 87). While procedures and mechanisms are in place for disciplinary measures for the judiciary of lower courts, there is no such mechanism for the superior courts. The rules of the Constitutional Council (a matter that has been disputed in litigation) do not provide guidance on the process to be adopted for approval /disapproval of nominations made by the President to these courts. There is no judicial review of legislation in Sri Lanka. In fact, we are governed under a constitution that provides for the enactment of constitutional amendments or law reform that are inconsistent with the Constitution (with approval at a referendum). These are some aspects that require review and discussion in relation to the further improvement of the judicial branch of the state in Sri Lanka. Many of us consider these reforms not just important but also urgent.

Special Determinations and their Scope

Generally, after a Bill is placed in the Order Paper of Parliament, any citizen may challenge it before the Supreme Court and the Court communicates its determination to the President and to the Speaker within three weeks (Article 121). When a Bill proposes to amend the Constitution, it requires approval by 2/3 absolute majority in Parliament. Therefore, if a Bill is challenged, the Court has to determine whether it also requires approval by the people at a referendum. The approval of the people is required if the Court determines that the Bill or any of its clauses is inconsistent with the entrenched clauses of our Constitution listed in Article 83. There are 10 entrenched clauses in our Constitution including the clause on Buddhism and freedom from torture. These clauses may only be amended with 2/3 in Parliament and approval by the People.

The presentation of the Bill and proceedings before Court is a reminder, yet again, of the sheer inadequacy of the manner in which the Constitution is amended or how we engage in law reform. Within a matter of three weeks, the Supreme Court is required to exercise its ‘pre-enactment’ judicial review. In this case, 65 petitioners rushed to Court to challenge the 22A bill and eight others the amendment to the Judicature Act. The hearings are conducted under severe time-pressure, including, in this instance, without a right of reply for the petitioners to the submissions by the Attorney-General. In the proceedings related to pre-enactment review, I cannot help but notice the irony of the process. At least in theory, the Attorney-General is the guardian of the Constitution and, therefore, is required to act in trust, for the benefit of the People. In these hearings, however, the Attorney-General, by and large, presents and defends the policies of the government. In theory, the government represents the people. The petitioners, too, bring to Court the concerns of the people (to the extent that they are presented by the petitioners) through counsel who often appear pro-bono for them. One possible way out of this dilemma is to consider a possibility for the Attorney-General to participate in these proceedings on the basis of the Constitution and for the government to retain its own counsel to make submissions defending its policies.

Two Constitutional Issues

The Court was faced with two constitutional questions in hearing these petitions. First, whether the petitions required the full court to hear and determine the matter since the Bill involved the retirement age of the sitting judges as well. Second, the Court had to determine whether the proposed amendment had a negative impact on judicial independence, whether judicial independence was an aspect of the entrenched clauses of our Constitution and if both those questions were answered in the affirmative, whether the Bill required approval at a referendum. Previously, the Court has determined that in reviewing a Bill, Court will not inquire into the desirability of the proposed reform but limit itself to determining whether any clauses of a Bill are inconsistent with the entrenched clauses of Constitution and would therefore require approval by the people at a referendum.

Constituting the Bench

In the Supreme Court, benches ordinarily comprise three judges, and the Chief Justice is vested with discretion to constitute larger benches of five or more judges (Article 132). In ‘the opinion of the Chief Justice’ the question involved must be one of ‘general and public importance’. The decision to constitute a larger bench may be the Chief Justice’s decision, or on the request of at least two of the judges hearing the matter or at the request of a petitioner. In the Dissolution case (2018) the Chief Justice himself constituted a Bench of seven judges.

The Chief Justice had constituted a Bench of five judges to hear this matter, of different years of seniority in the Court. Court rejected the request for a full bench on the basis that the Bench did not have a conflict of interest and that a five-judge Bench was the appropriate use of the resources of the Court, particularly in light of the fact that the Court was due to hear petitions regarding another bill at the same time. For the first time, the Court comments on the administrative functions of the Chief Justice, the difficulties in case management under resource constraints and the internal procedures of a bench when dealing with a Special Determination. Ironically, this reminds us that for several months, the vacancies in the Supreme Court and the Court of Appeal have remained while the President and the Government claim that they are committed to addressing laws delays.

Even if the Court had taken the view that there was a conflict of interest, as a matter of necessity, the Court had to make a determination on this Bill. The Court, in its wisdom, determined that a five-judge bench was constitutionally adequate. Yet, it could be argued, that in this context, a full bench or a fuller bench, would have satisfied all concerned that the Court had taken the maximum measures it could, to avoid any perceptions of a conflict of interest. That interest of the Court and of our constitutional system, arguably is constitutionally more important than ensuring efficiency in case-management.

The Bill and Independence of the Judiciary

The independence of the judiciary includes the following dimensions: personal and institutional; negative and positive; the actual and the perceived; and procedural and substantive. These dimensions require a principled assessment as well as a situated or contextual assessment.

‘Independence of the Judiciary’ is explicitly mentioned only twice in our Constitution: in the preamble, as part of our ‘intangible heritage’ which ‘guarantees’ our dignity and well-being and as the sub-heading for chapter XV of the Constitution. The independence of the judiciary, as part of our intangible heritage, has to be understood as a foundational constitutional concept and as a constitutional principle. In its operationalisation, the concept and the principle have to be interpreted and applied in context. This is where the contestations on the 22nd Amendment come alive. None of the entrenched clauses directly refers to the independence of the judiciary. However, in its recent jurisprudence, the Court has held that the independence of the judiciary has to be read into Article 3 of our Constitution, which is entrenched. Article 3 states that ‘sovereignty is in the People and is inalienable’ and further that our sovereignty includes ‘powers of government, fundamental rights and the franchise.’ In this Determination, Court endorses this interpretation.

The Court rightly notes that matters of policy are not reviewable by court except if such policies are vague or manifestly unreasonable. The Court determines that petitioners were wrong to argue that the extension of the age of retirement of the judiciary was an encroachment on the independence of the judiciary. Notably, the Court does not explain the independence of the judiciary as a constitutional concept except to note that the Constitution ‘guarantees that Judges will be able to make decisions free of influence and based only on relevant facts and law.’ (p 74). The Court further notes that while a reduction of the term or a reduction in the salaries of judges would undermine judicial independence, the increase of salaries of judges could hardly be considered as impacting judicial independence.

The Court considered several comparative examples in considering whether or not the extension of the age of retirement has been determined to have undermined the independence of the judiciary elsewhere. However, in each of those examples the broader constitutional context has a material bearing on the conclusions reached. In India, the selection of judges for appointment is through the Collegium System which comprises the judiciary. In the UK, the age of retirement was raised after extensive consultation between July – October 2020. As reported by the UK government, 1004 responses were received from the judiciary, the legal profession and other stakeholders. It is thereafter that the decision was implemented. It is relevant to note here that despite the lack of consultation, the lower judiciary and the Bar went on record opposing this Amendment.

In its wisdom, the Court agreed with the submissions made by the Attorney-General that since the extension of the age of retirement applied to all the judges, it was non-discriminatory and non-discretionary and therefore was ‘not at the whim and fancy of the Executive.’ (p 83) The Court reproduces a Note to the Cabinet (3 July 2026) which sets out the reasons for the Government’s policy decision. Notably, in a sector where no constitutional reforms have been made, except to require approval for appointments by the Constitutional Council, the Note provides no justification for selectively focusing on the age of retirement. The excerpts of the Note reproduced in the Determination make no reference to the other two reforms proposed.

The Social Justice Questions and Constitutionalism

For us, the constitutional questions have to be answered within the broader political context. From the citizen’s perspective, even the increase of the salaries of judges, if implemented under questionable, selective or opaque circumstances, can give rise to questions, concerns and a weakening of public confidence. Facts take colour from their context. This reminds me of another question on which there has been some debate in Sri Lanka, which is, whether Sri Lanka should establish a separate Constitutional Court which will adjudicate on constitutional matters thereby permitting a broader jurisdiction and mandate.

Some others have even described law as a colonial tool that has oppressed most in society. Some have argued that social justice requires that we marginalise or even dispense with commitments to liberal values such as rules of procedure and values of democracy such as diversity of opinion. That Sri Lankans have experienced exploitation, that democracy has been abused for state capture, through its Constitution and law, is true. As much as the law has been a tool for exploitation and abuse, it has also been a tool for liberation and social justice. Victims of human rights violations and abuse of law, often the vulnerable in our society, often have no recourse but the law. They seek it, even if to fail. Justice, too, is heavily contested and should remain so. Its meaning cannot be the monopoly of one social class, a political party or a ruling elite. At the same time, there ought to be commitments we can make as a polity to values, procedures and substantive outcomes that bring liberal commitments to rights and procedure with those of social justice. Furthermore, we must avoid the trap of romanticising ‘the people.’ We, the people, have actively sought and cultivated political patronage and participated in practices that undermine our common good, such as daily acts of violence, racism, patriarchy, corruption, abuse whether at home, at work or in the public domain.

Returning to the question of law, constitutions and justice, we should be vary of a ‘them vs us’ approach, particularly when they are propagated by those with political, cultural or economic power. The Constitution allows the Cabinet to place a bill before the People for their approval through a referendum (Article 120). Perhaps, taking this path, even if it carries a significant financial cost, may have allowed the government to put to rest the opposition to the 22nd Amendment. It is ironic that under a Constitution that declares the people to be sovereign, the only time a bill has been put to the people, was to postpone the exercise of their franchise (4th Amendment to the Constitution 1982).

Illiberal Slippage and/or Democratic Backsliding?

Serious issues of constitutional politics of this nature require that a strong government (which is what we have, with a charismatic leader and 2/3 in Parliament) is matched by a strong Opposition. What we have, instead, for the most part, are some politicians and political parties that have no credibility on matters related to the judiciary, mobilising against the government and claiming to defend the independence of the judiciary. While that tragi-comedy writes itself, we the citizens ought to be concerned about the lack of healthy political competition, an essential feature of a sustainable democracy and the disregard by the government of the reasonable voices within the Opposition.

Illiberal slippage or democratic backsliding has been identified as a risk for regimes that have led a transition to democracy. In a system headed by an Executive President, such a risk is all too real, as we know all too well. Ad hoc, piece-meal constitutional amendments of this nature place us on that path. In this political moment, many truths compete with each other. It is true that Sri Lanka made a distinct transition to democracy. It was made in stages starting from 2022. No single political party or social movement can claim that transition as their own. We cannot deny the organic dynamics of that transition. It is true that this transition has a class dimension to it. For certain, the political elite of the past enjoy diminished political capital and mileage, at least for now. The professional elite, depending on one’s perspective, too, arguably enjoy diminished traction. The ground beneath us is shifting. It is also true that within the limited electoral cycle, limited political capital, and in a context where former authoritarian forces remain electorally relevant, institutional reform is difficult. Situated in this broader context, there is cause for concern about the 22nd Amendment. It has weakened our transition to democracy and placed our constitutional recovery at risk.

Why do students ‘fear’ algebra?

Published

on

by R N A de Silva
rnades@gmail.com

“I was good with numbers and liked mathematics, but it changed when letters started to replace numbers”- such sentiments are common expressions that we hear. Perhaps the challenges that the students face in mathematics as a school subject are mainly due to the fear of algebra. For many students the transition into secondary education brings this profound sense of academic dread – algebra. This anxiety is more a structural byproduct of human minds adapt to radical shifts in thinking than a personal failure of the individual student. Many students who have been dealing only with numbers suddenly feel that they are in unfamiliar territory as they have to combine numbers with letters, symbols and rules. Dismantling this fear has to be done by the educators through reshaping how it is introduced and contextualised so that it becomes an accessible gateway of logical reasoning.

Let us look at the reasons for the development of the fear of algebra.

The Challenge of the ‘unknown’

In the first few years of formal schooling, mathematics becomes a tangible experience. They can count with their fingers or tools like counters and beads. They can measure lengths of tables or rooms or divide boxes or fruits into fractions. The operations are predictable and visible. There is stability in numbers as three is always a three. Algebra disrupts this stability. Letters such as x and y are introduced which do not possess fixed values. Suddenly, they are asked to manipulate symbols which they cannot physically see. This demand for abstract thinking can leave students bewildered. When a student enters this stage prematurely or without adequate background, the brain struggles to attach meaning to symbols.

Foundational gaps

As mathematics is uniquely sequential and cumulative, a weak grasp of basic skills may hinder progress in algebra. If a student leaves primary school with a shaky understanding of mathematical operations, it will be a disruption to their ability to follow algebraic steps. Solving an algebraic equation such as 3x – 2 = 10 consists of two levels of cognitive processing. Determining the properties applicable to isolate the variable requires higher order strategic thinking while executing the basic arithmetic operations requires lower order execution. If difficulties arise with lower order execution, they lose track of the broader algebraic strategy. Building confidence starts with consistent practice of foundational skills.

Fear of making mistakes

In general, a problem in algebra may involve a multi-step process unlike in a standard arithmetic problem. This increases the chances of making mistakes thus resulting in an incorrect final answer although the process is correct. Unfortunately, the traditional grading systems often rely heavily on the final result than the logical process. This can lead to an intense fear of failure. Subsequently, this threat of failure may turn into a highly stressful experience.

Now, let us consider strategies to eliminate or minimise the growth of the fear of algebra.

Using concrete examples to clarify abstract ideas

It is essential for teachers to use concrete examples to bridge the gap between simple mathematics and symbolic reasoning, rather than forcing students to jump to abstractness unassisted. A few examples are given below.

Solving an equation such as 3x + 10 = 100 can be introduced in the form of a story. ‘I went to a shop and gave the shopkeeper Rs 100 asking for three candies. He gave me three candies and also Rs 10 as balance. What is the price that I have paid for a candy?’ The gradual introduction of a variable will be made easier with such narratives.

Figure 1

Equations can also be framed as games of balancing on a scale to understand what you do to one side of the scale need to be done on the other side too to maintain balance. (See figure 1)

Factorisation is an area that many students struggle with. The need for a quadratic expression to be converted to a product can be shown through tiles that need to be fully covered in a rectangular area. Factors of X^2 + 5x + 6 can be manipulated with tiles as shown below to obtain the answer as (x + 3)(x + 2). (See figure 2)

Figure 2

With such demonstration, symbols lose their mystical quality.

Embrace mistakes as stepping stones

Errors should be treated as valuable diagnostic data by the teachers where the students are able to dissect where a problem went wrong. Creating a supportive learning environment that normalises mistakes as learning opportunities helps reduce anxiety and encourages persistence.

Assessment should also be done to reward logical reasoning and correct algebraic procedures without giving too much weight to minor arithmetical errors. Formative assessments need to be conducted regularly as algebra is introduced, before the students become overwhelmed by the complexities of cumulative assessments.

Connect with real life applications

Many students fail to see how algebra connects to everyday life, making it harder for them to stay motivated. Wherever possible, teachers can demonstrate practical uses of algebra such as tracking expenses to find the balance remaining after expenditure, estimating travel time or fuel consumption, use of recipes dealing with proportion, tiling the floor of a room and finding measurements for a scaled model of a building. Showing how algebra helps in designing games or solving real-world problems enhances interest and comprehension.

Algebra may feel intimidating at first, but it is an opportunity for students to sharpen their reasoning, resilience and problem-solving skills. When the anxiety is eliminated, algebra reveals itself as an extremely useful and elegant toolkit for problem solving. Using appropriate teaching methods algebra can be transformed from an intimidating barrier into a powerful bridge to intellectual exercise. “An ounce of algebra is worth a ton of verbal argument.” said John Haldane.

Two Badulla forests covering nearly 200 hectares gazetted as reserves

Published

on

Badulla District

By Ifham Nizam

Two forest areas in the Badulla District — Mahiyanganaya Moopalana, covering 29.79 hectares, and Mahiyanganaya Heerussagala, covering 168.09 hectares — have been officially gazetted as forest reserves, bringing a combined 197.88 hectares of ecologically important land under formal protection.

The two forests, located in the Riddimaliyadda Divisional Secretariat Division within the Mahiyanganaya forest range, are dry-monsoon forests that provide habitats for a variety of native plant and animal species.

The declarations form part of the Government’s Vanaspathi forest conservation programme, under which 20 forests, covering a total of 9,538.68 hectares, across six districts, were granted protected status. The latest additions have taken the forest area, protected under the programme, to nearly 65,000 hectares, according to reports.

Environment Minister Dr. Dammika Patabendi and Deputy Minister Anton Jayakody were associated with the conservation programme.

Commenting on the significance of the declarations, Dr. Patabendi said the reserves are intended to deliver long-term environmental, ecological and social benefits.

“Through the declaration of these reserves, we aim to protect Sri Lanka’s biodiversity, safeguard water sources and watershed areas, create opportunities for eco-tourism, and preserve areas of archaeological importance found within these forests,” the Minister said.

Moopalana Forest

The 29.79-hectare Moopalana Forest is a dry-monsoon forest containing a range of natural resources and providing habitat for native species.

The forest is also linked to the livelihoods of surrounding rural communities. Local people obtain forest-based products such as rattan, veniwel and kitul, making the area significant, not only for biodiversity conservation, but also for traditional livelihood activities.

Several small waterways that become active during the rainy season are also found within the forest.

Heerussagala Forest

The larger 168.09-hectare Heerussagala Forest is likewise a dry-monsoon forest with important ecological resources and habitats for native flora and fauna.

The forest also has a direct connection with the local water system, with Nagadeepa Wewa being fed by the forest area.

Adding to its significance is the nearby Nagadeepa Temple, an area associated with archaeological value.

The protection of the forest, therefore, encompasses ecological, water-resource and cultural considerations.

The Ministry of Environment states that its broader approach to environmental management is based on sustainable natural-resource management, with government agencies, communities and other stakeholders participating in conservation efforts.

The gazetting of Moopalana and Heerussagala consequently places nearly 200 hectares of Badulla’s dry-monsoon forest under formal protection, strengthening the legal framework for conserving their biodiversity, water resources and associated cultural values.

The two forests are among 20 forest areas officially declared reserves in the latest phase of the Vanaspathi programme, which covers forests in Badulla, Anuradhapura, Ampara, Kegalle, Nuwara Eliya and Vavuniya.

For the communities surrounding these forests, their protection also represents the preservation of natural resources that support local livelihoods and water systems — while ensuring that these forest ecosystems remain part of Sri Lanka’s natural heritage for future generations, says Environment Ministry Consultant Dr. Ravindra Kariyawasam.
