Mathematics examinations or mathematics curriculum?
Some people say that it is not necessary for a Grade 10 student to buy an ordinary scientific calculator because they have smartphones with built-in calculators. If not, it is easy to install a calculator app on mobile phones. A smartphone should not be used as a calculator during a mathematics test or a mathematics exam because it can be used for cheating. In the UK and other developed countries students have to keep their smartphones in their school bags or in their lockers outside the classroom during mathematics tests and exams.

R. N.A. De Silva has, in a recent article, provided some useful tips to students as regards preparation for mathematics examinations. Trained teachers and graduates with professional qualifications are familiar with this topic. All mathematics teachers have a duty to help the students with revision.
The more important task is to salvage the Sri Lankan O/Level mathematics students from the abyss that they have fallen into, viz. the implications and the retarding effect of the use of obsolete Log Tables. The Minister of Education, Senior Ministry Officials and the NIA are oblivious to the important and interesting things that have happened in Grades 10 and 11 mathematics in the UK, other parts of Europe, Japan, Canada, China and elsewhere. They have been like frogs in a well for almost half a century. Here are two important facts:
1. O/Level mathematics students in Sri Lanka are 46 years behind their counterparts in the UK and in other developed countries. Ordinary Scientific calculators were introduced to the O/Level mathematics classrooms in the UK way back in 1977. Prior to that those students used Slide Rules to facilitate their mathematical calculations. Ordinary scientific calculators give the values of Sine, Cos, Tan and their Inverses, Log, LN, exponential powers, square roots, squares, reciprocals, factorials, etc., at the press of a button, in addition to performing arithmetic functions. There is no memory to store mathematical formulae, etc. It is an invaluable tool for solving sophisticated and interesting mathematical problems and also problems in ordinary statistics. It has paved the way for achieving high standards in O/Level Mathematics in those countries.
Just compare the maths questions in the Cambridge IGCSE or the London O/Level Maths Exam with the questions in the Sri Lankan O/Level maths exam and you will see how far our students have fallen behind.
The Cambridge O/Level examination was replaced by the GCSE and the IGCSE (International General Certificate of Secondary Education) a few decades ago.
I am not referring to Programmable Calculators and Graphic Display Calculators (GDC), meaning devices with a small screen that can display graphs, perform statistical calculations like the Z- Score for large samples, show Matrix calculations, provide solutions to algebraic equations, etc., at the press of a few buttons. GDC is a compulsory item for A/Level mathematics students in the UK and in all developed countries.
Some teachers say that by using ordinary scientific calculators in Grades 10 and 11, students will not acquire the ability to carry out mental arithmetic calculations. This is not true because
(i). Calculators are introduced in Grade 10. Maths teachers have five years of Primary School and three years of Middle school (Grades 7, 8 and 9) i.e. a total of eight years to inculcate sufficient mental arithmetic skills in their students before the calculators are introduced in Grade 10!
(ii). In the IGCSE and in the London O/Level Mathematics Exams calculators are not allowed for Paper 1. Preparation for Paper 1 requires the acquisition of mental arithmetic skills, e.g., one lesson per week in class in Grades 10 and 11 in which calculators are not allowed. Sri Lanka could follow suit.
Some people say that it is not necessary for a Grade 10 student to buy an ordinary scientific calculator because they have smartphones with built-in calculators. If not, it is easy to install a calculator app on mobile phones. A smartphone should not be used as a calculator during a mathematics test or a mathematics exam because it can be used for cheating. In the UK and other developed countries students have to keep their smartphones in their school bags or in their lockers outside the classroom during mathematics tests and exams.
An ordinary scientific calculator costs less than 10 % of the price of a smartphone.
Sri Lankan students in International Schools sit the IGCSE or the London O/Level mathematics exams where ordinary scientific calculators are allowed. These students have made big strides in learning mathematics by using the calculators. Only the rich can send their children to International Schools in Sri Lanka. Millions of poor Sri Lankan students do not have calculators.
Our Minister of Education has announced that the government was planning to transform the country’s education system by introducing ‘’STEAM’ (Science, Technology, Engineering, Arts and Mathematics). Maintaining high standards in O/Level Mathematics is the key to a successful implementation of STEAM programme. Unfortunately, the Education Minister and top education official are not aware of the fact that the only way to improve the standard of O/Level Mathematics is to do what the developed countries have done, i. e., revamping the O/Level mathematics syllabus and to introducing the ordinary scientific calculator in Grades 10 & 11. If they do it, it will be an important piece of curriculum development.
Bear in mind that the UK and other developed countries have taken another important step during the last 20 years; they have introduced the Graphic Display Calculator (GDC) to the O/Level Mathematics class and by providing a Core Exam and an Extended Exam. In the Cambridge IGCSE Mathematics Exams, Papers 1, 3, and 5 constitute the Core Exam. Papers 2 ,4 and 6 constitute the Extended Exam. Calculators are not allowed in Papers 1 and 2.
The Core Exam is a boon to students who have very little or no mathematical ability. More on this in my next article.
By using Log Tables, our Sri Lankan O/Level students have to spend a lot of time to solve an IGCSE (Extended Syllabus) exam problem or a London O/Level mathematics exam problem because the use of Log Tables takes a long time to work out the Squares, Square Roots, exponential powers, reciprocals , LN , factorials, etc., and that is tedious work while their counterparts in developed countries do that in a few seconds by pressing a couple of buttons in an ordinary scientific calculator.
The Calculator has given them more motivation to learn mathematics.
O/Level students in the UK have graduated from the ordinary scientific calculator to the Graphic Display Calculator (GDC) thereby improving their ability to solve more sophisticated, more important and more interesting problems in mathematics, statistics and physics. Sri Lankan O/Level students are compelled to use obsolete Log Tables.
Hats off to that Minister of Education who introduced the ordinary scientific calculator to the Sri Lankan A/ Level Mathematics classroom and to the A/Level Mathematics Exam a few years ago. That was a small step in the right direction. Minister Susil Premjayantha, please revamp the O/Level mathematics syllabus and introduce the ordinary scientific calculator to Grades 10 and 11 now. That will ensure a big boost for your STEAM programme and yield benefits for the Sri Lankan economy.

Trade preferences to support post-Ditwah reconstruction
The manner in which the government succeeded in mobilising support from the international community, immediately after the devastating impact of Cyclone Ditwah, may have surprised many people of this country, particularly because our Opposition politicians were ridiculing our “inexperienced” government, in the recent past, for its inability to deal with the international community effectively. However, by now it is evident that the government, with the assistance of the international community and local nongovernmental actors, like major media organisations, has successfully managed the recovery efforts. So, let me begin by thanking them for what they have done so far.
Yet, some may argue that it is not difficult to mobilise the support for recovery efforts from the international community, immediately after any major disaster, and the real challenge is to sustain that support through the next few weeks, months and years. Because the recovery process, more specifically the post-recovery reconstruction process, requires long-term support. So, the government agencies should start immediately to focus on, in addition to initial disaster relief, a longer-term strategy for reconstruction. This is important because in a few weeks’ time, the focus of the global community may shift elsewhere … to another crisis in another corner of the world. Before that happens, the government should take initiatives to get the support from development partners on appropriate policy measures, including exceptional trade preferences, to help Sri Lanka in the recovery efforts through the medium and the long term.
Use of Trade Preferences to support recovery and reconstruction
In the past, the United States and the European Union used exceptional enhanced trade preferences as part of the assistance packages when countries were devastated by natural disasters, similar to Cyclone Ditwah. For example:
- After the devastating floods in Pakistan, in July 2010, the EU granted temporary, exceptional trade preferences to Pakistan (autonomous trade preferences) to aid economic recovery. This measure was a de facto waiver on the standard EU GSP (Generalised Scheme of Preferences) rules. The preferences, which were proposed in October 2010 and were applied until the end of 2013, effectively suspended import duties on 75 types of goods, including textiles and apparel items. The available studies on this waiver indicate that though a significant export hike occurred within a few months after the waiver became effective it did not significantly depress exports by competing countries. Subsequently, Pakistan was granted GSP+ status in 2014.
- Similarly, after the 2015 earthquakes in Nepal, the United States supported Nepal through an extension of unilateral additional preferences, the Nepal Trade Preferences Programme (NTPP). This was a 10-year initiative to grant duty-free access for up to 77 specific Nepali products to aid economic recovery after the 2015 earthquakes. This was also a de facto waiver on the standard US GSP rules.
- Earlier, after Hurricanes Mitch and Georges caused massive devastation across the Caribbean Basin nations, in 1998, severely impacting their economies, the United States proposed a long-term strategy for rebuilding the region that focused on trade enhancement. This resulted in the establishment of the US Caribbean Basin Trade Partnership Act (CBTPA), which was signed into law on 05 October, 2000, as Title II of the Trade and Development Act of 2000. This was a more comprehensive facility than those which were granted to Pakistan and Nepal.

What type of concession should Sri Lanka request from our development partners?
Given these precedents, it is appropriate for Sri Lanka to seek specific trade concessions from the European Union and the United States.
In the European Union, Sri Lanka already benefits from the GSP+ scheme. Under this arrangement Sri Lanka’s exports (theoretically) receive duty-free access into the EU markets. However, in 2023, Sri Lanka’s preference utilisation rate, that is, the ratio of preferential imports to GSP+ eligible imports, stood at 59%. This was significantly below the average utilisation of other GSP beneficiary countries. For example, in 2023, preference utilisation rates for Bangladesh and Pakistan were 90% and 88%, respectively. The main reason for the low utilisation rate of GSP by Sri Lanka is the very strict Rules of Origin requirements for the apparel exports from Sri Lanka. For example, to get GSP benefits, a woven garment from Sri Lanka must be made from fabric that itself had undergone a transformation from yarn to fabric in Sri Lanka or in another qualifying country. However, a similar garment from Bangladesh only requires a single-stage processing (that is, fabric to garment) qualifies for GSP. As a result, less than half of Sri Lanka’s apparel exports to the EU were ineligible for the preferences in 2023.
Sri Lanka should request a relaxation of this strict rule of origin to help economic recovery. As such a concession only covers GSP Rules of Origin only it would impact multilateral trade rules and would not require WTO approval. Hence could be granted immediately by the EU.
United States
Sri Lanka should submit a request to the United States for (a) temporary suspension of the recently introduced 20% additional ad valorem duty and (b) for a programme similar to the Nepal Trade Preferences Programme (NTPP), but designed specifically for Sri Lanka’s needs. As NTPP didn’t require WTO approval, similar concessions also can be granted without difficulty.
Similarly, country-specific requests should be carefully designed and submitted to Japan and other major trading partners.

Lasting power and beauty of words
Novelists, poets, short story writers, lyricists, politicians and columnists use words for different purposes. While some of them use words to inform and elevate us, others use them to bolster their ego. If there was no such thing called words, we cannot even imagine what will happen to us. Whether you like it or not everything rests on words. If the Penal Code does not define a crime and prescribe a punishment, judges will not be able to convict criminals. Even the Constitution of our country is a printed document.
A mother’s lullaby contains snatches of sweet and healing words. The effect is immediate. The baby falls asleep within seconds. A lover’s soft and alluring words go right into his or her beloved. An army commander’s words encourage soldiers to go forward without fear. The British wartime Prime Minister Winston Churchill’s words still ring in our ears: “… we shall defend our Island, whatever the cost may be, we shall fight on the beaches, we shall fight on the landing grounds, we shall fight in the fields and in the streets, we shall fight in the hills; we shall never surrender …”
Writers wax eloquent on love. English novelist John Galsworthy wrote: “Love is no hot-house flower, but a wild plant, born of a wet night, born of an hour of sunshine; sprung from wild seed, blown along the road by a wild wind. A wild plant that, when it blooms by chance within the hedge of our gardens, we call a flower; and when it blooms outside we call a weed; but flower or weed, whose scent and colour are always wild.” While living in a world dominated by technology, we often hear a bunch of words that is colourless and often cut to verbal ribbons – “How R U” or “Luv U.” Such words seem to squeeze the life out of language.
Changing medium
Language is a constantly changing medium. New words and forms arrive and old ones die out. Whoever thought that the following Sinhala words would find a place in the Oxford English Dictionary? “Asweddumize, Avurudu, Baila, Kiribath, Kottu Roti, Mallung, Osari, Papare, Walawwa and Watalappan.” With all such borrowed words the English language is expanding and remains beautiful. The language helps us to express subtle ideas clearly and convincingly.
You are judged by the words you use. If you constantly use meaningless little phrases, you will be considered a worthless person. When you read a well-written piece of writing you will note how words jump and laugh on the paper or screen. Some of them wag their tails while others stand back like shy village belles. However, they serve a useful purpose. Words help us to write essays, poems, short stories and novels. If not for the beauty of the language, nobody will read what you write.
If you look at the words meaningfully, you will see some of them tap dancing while others stand to rigid attention. Big or small, all the words you pen form part of the action or part of the narrative. The words you write make your writing readable and exciting. That is why we read our favourite authors again and again.
Editorials
If a marriage is to succeed, partners should respect and love each other. Similarly, if you love words, they will help you to use them intelligently and forcefully. A recent survey in the United States has revealed that only eight per cent of people read the editorial. This is because most editorials are not readable. However, there are some editorials which compel us to read them. Some readers collect such editorials to be read later.
Only a lover of words would notice how some words run smoothly without making a noise. Other words appear to be dancing on the floor. Some words of certain writers are soothing while others set your blood pounding. There is a young monk who is preaching using simple words very effectively. He has a large following of young people addicted to drugs. After listening to his preaching, most of them have given up using illegal drugs. The message is loud and clear. If there is no demand for drugs, nobody will smuggle them into the country.
Some politicians use words so rounded at the edges and softened by wear that they are no longer interesting. The sounds they make are meaningless and listeners get more and more confused. Their expressions are full of expletives the meaning of which is often soiled with careless use of words.
Weather-making
Some words, whether written or spoken, stick like superglue. You will never forget them. William Vergara in his short essay on weather-making says, “Cloud-seeding has touched off one of the most baffling controversies in meteorological history. It has been blamed for or credited with practically all kinds of weather. Some scientists claim seeding can produce floods and hail. Others insist it creates droughts and dissipates clouds. Still others staunchly maintain it has no effect at all. The battle is far from over, but at last one clear conclusion is beginning to emerge: man can change the weather, and he is getting better at it.”
There are words that nurse the ego and heal the heart. The following short paragraph is a good example. S. Radhakrishnan says, “In every religion today we have small minorities who see beyond the horizon of their particular faith, not through religious fellowship is possible, not through the imposition of any one way on the whole but through an all-inclusive recognition that we are all searchers for the truth, pilgrims on the road, that we all aim at the same ethical and spiritual standard.”
There are some words joined together in common phrases. They are so beautiful that they elevate the human race. In the phrase ‘beyond a shadow of doubt’, ‘a shadow’ connotes a dark area covering light. ‘A doubt’ refers to hesitancy in belief. We use such phrases blithely because they are exquisitely beautiful in their structure. The English language is a repository of such miracles of expression that lead to deeper understanding or emphasis.
Social media
Social media use words powerfully. Sometimes they invent new words. Through the social media you can reach millions of viewers without the intervention of the government. Their opinion can stop wars and destroy tyrants. If you use the right words, you can even eliminate poverty to a great extent.
The choice of using powerful words is yours. However, before opening your mouth, tap the computer, unclip a pen, write a lyric or poem, think twice of the effect of your writing. When you talk with a purpose or write with pleasure, you enrich listeners and readers with your marvellous language skills. If you have a command of the language, you will put across your point of view that counts. Always try to find the right words and change the world for a better place for us to live.

Why Sri Lanka Still Has No Doppler Radar – and Who Should Be Held Accountable
Eighteen Years of Delay:
Cyclone Ditwah has come and gone, leaving a trail of extensive damage to the country’s infrastructure, including buildings, roads, bridges, and 70% of the railway network. Thousands of hectares of farming land have been destroyed. Last but not least, nearly 1,000 people have lost their lives, and more than two million people have been displaced. The visuals uploaded to social media platforms graphically convey the widespread destruction Cyclone Ditwah has caused in our country.
The purpose of my article is to highlight, for the benefit of readers and the general public, how a project to establish a Doppler Weather Radar system, conceived in 2007, remains incomplete after 18 years. Despite multiple governments, shifting national priorities, and repeated natural disasters, the project remains incomplete.
Over the years, the National Audit Office, the Committee on Public Accounts (COPA), and several print and electronic media outlets have highlighted this failure. The last was an excellent five-minute broadcast by Maharaja Television Network on their News First broadcast in October 2024 under a series “What Happened to Sri Lanka”
The Agreement Between the Government of Sri Lanka and the World Meteorological Organisation in 2007.
The first formal attempt to establish a Doppler Radar system dates back to a Trust Fund agreement signed on 24 May 2007 between the Government of Sri Lanka (GoSL) and the World Meteorological Organisation (WMO). This agreement intended to modernize Sri Lanka’s meteorological infrastructure and bring the country on par with global early-warning standards.
The World Meteorological Organisation (WMO) is a specialized agency of the United Nations established on March 23, 1950. There are 193 member countries of the WMO, including Sri Lanka. Its primary role is to promote the establishment of a worldwide meteorological observation system and to serve as the authoritative voice on the state and behaviour of the Earth’s atmosphere, its interaction with the oceans, and the resulting climate and water resources.
According to the 2018 Performance Audit Report compiled by the National Audit Office, the GoSL entered into a trust fund agreement with the WMO to install a Doppler Radar System. The report states that USD 2,884,274 was deposited into the WMO bank account in Geneva, from which the Department of Metrology received USD 95,108 and an additional USD 113,046 in deposit interest. There is no mention as to who actually provided the funds. Based on available information, WMO does not fund projects of this magnitude.
The WMO was responsible for procuring the radar equipment, which it awarded on 18th June 2009 to an American company for USD 1,681,017. According to the audit report, a copy of the purchase contract was not available.
Monitoring the agreement’s implementation was assigned to the Ministry of Disaster Management, a signatory to the trust fund agreement. The audit report details the members of the steering committee appointed by designation to oversee the project. It consisted of personnel from the Ministry of Disaster Management, the Departments of Metrology, National Budget, External Resources and the Disaster Management Centre.
The Audit Report highlights failures in the core responsibilities that can be summarized as follows:
· Procurement irregularities—including flawed tender processes and inadequate technical evaluations.
· Poor site selection
—proposed radar sites did not meet elevation or clearance requirements.
· Civil works delays
—towers were incomplete or structurally unsuitable.
· Equipment left unused
—in some cases for years, exposing sensitive components to deterioration.
· Lack of inter-agency coordination
—between the Meteorology Department, Disaster Management Centre, and line ministries.
Some of the mistakes highlighted are incomprehensible. There is a mention that no soil test was carried out before the commencement of the construction of the tower. This led to construction halting after poor soil conditions were identified, requiring a shift of 10 to 15 meters from the original site. This resulted in further delays and cost overruns.
The equipment supplier had identified that construction work undertaken by a local contractor was not of acceptable quality for housing sensitive electronic equipment. No action had been taken to rectify these deficiencies. The audit report states, “It was observed that the delay in constructing the tower and the lack of proper quality were one of the main reasons for the failure of the project”.
In October 2012, when the supplier commenced installation, the work was soon abandoned after the vehicle carrying the heavy crane required to lift the radar equipment crashed down the mountain. The next attempt was made in October 2013, one year later. Although the equipment was installed, the system could not be operationalised because electronic connectivity was not provided (as stated in the audit report).
In 2015, following a UNOPS (United Nations Office for Project Services) inspection, it was determined that the equipment needed to be returned to the supplier because some sensitive electronic devices had been damaged due to long-term disuse, and a further 1.5 years had elapsed by 2017, when the equipment was finally returned to the supplier. In March 2018, the estimated repair cost was USD 1,095,935, which was deemed excessive, and the project was abandoned.
COPA proceedings
The Committee on Public Accounts (COPA) discussed the radar project on August 10, 2023, and several press reports state that the GOSL incurred a loss of Rs. 78 million due to the project’s failure. This, I believe, is the cost of constructing the Tower. It is mentioned that Rs. 402 million had been spent on the radar system, of which Rs. 323 million was drawn from the trust fund established with WMO. It was also highlighted that approximately Rs. 8 million worth of equipment had been stolen and that the Police and the Bribery and Corruption Commission were investigating the matter.
JICA support and project stagnation
Despite the project’s failure with WMO, the Japan International Cooperation Agency (JICA) entered into an agreement with GOSL on June 30, 2017 to install two Doppler Radar Systems in Puttalam and Pottuvil. JICA has pledged 2.5 billion Japanese yen (LKR 3.4 billion at the time) as a grant. It was envisaged that the project would be completed in 2021.
Once again, the perennial delays that afflict the GOSL and bureaucracy have resulted in the groundbreaking ceremony being held only in December 2024. The delay is attributed to the COVID-19 pandemic and Sri Lanka’s economic crisis.
The seven-year delay between the signing of the agreement and project commencement has led to significant cost increases, forcing JICA to limit the project to installing only one Doppler Radar system in Puttalam.
Impact of the missing radar during Ditwah
As I am not a meteorologist and do not wish to make a judgment on this, I have decided to include the statement issued by JICA after the groundbreaking ceremony on December 24, 2024.
“In partnership with the Department of Meteorology (DoM), JICA is spearheading the establishment of the Doppler Weather Radar Network in the Puttalam district, which can realize accurate weather observation and weather prediction based on the collected data by the radar. This initiative is a significant step in strengthening Sri Lanka’s improving its climate resilience including not only reducing risks of floods, landslides, and drought but also agriculture and fishery“.
Based on online research, a Doppler Weather Radar system is designed to observe weather systems in real time. While the technical details are complex, the system essentially provides localized, uptotheminute information on rainfall patterns, storm movements, and approaching severe weather. Countries worldwide rely on such systems to issue timely alerts for monsoons, tropical depressions, and cyclones. It is reported that India has invested in 30 Doppler radar systems, which have helped minimize the loss of life.
Without radar, Sri Lanka must rely primarily on satellite imagery and foreign meteorological centres, which cannot capture the finescale, rapidly changing weather patterns that often cause localized disasters here.
The general consensus is that, while no single system can prevent natural disasters, an operational Doppler Radar almost certainly would have strengthened Sri Lanka’s preparedness and reduced the extent of damage and loss.
Conclusion
Sri Lanka’s inability to commission a Doppler Radar system, despite nearly two decades of attempts, represents one of the most significant governance failures in the country’s disastermanagement history.
Audit findings, parliamentary oversight proceedings, and donor records all confirm the same troubling truth: Sri Lanka has spent public money, signed international agreements, received foreign assistance, and still has no operational radar. This raises a critical question: should those responsible for this prolonged failure be held legally accountable?
Now may not be the time to determine the extent to which the current government and bureaucrats failed the people. I believe an independent commission comprising foreign experts in disaster management from India and Japan should be appointed, maybe in six months, to identify failures in managing Cyclone Ditwah.
However, those who governed the country from 2007 to 2024 should be held accountable for their failures, and legal action should be pursued against the politicians and bureaucrats responsible for disaster management for their failure to implement the 2007 project with the WMO successfully.
Sri Lanka cannot afford another 18 years of delay. The time for action, transparency, and responsibility has arrived.
