Towards a knowledge-based economy Start with quality STEM teachers for every child

Deepani is a Grade 10 student who loves mathematics and science. Her parents are delighted and encourage her to continue in these fields, assuring her that she will have a bright future. But Deepani is worried that she is not learning all that she should – her teachers in both subjects are not the best and at times, Deepani has been unable to clarify the doubts in certain areas.


Deepani wonders whether she can continue in the field of sciences, if her teachers lack the competency to instruct and guide her. Without doing well in mathematics and sciences at the Ordinary Level Examination (O-Levels) next year, her dream to continue her studies in the science stream will be futile. 


Deepani is not alone in her concerns. The Institute of Policy Studies (IPS) research finds that at present, close to half the students who sit for O-Levels fail the exam. In fact, being unable to meet the minimum requirement of a credit pass (C grade) in mathematics or science at O-Levels is the main reason for the low number of students in the science streams in the Advanced Level (A-Level) classes. 


According to the 2016 School Census Preliminary Report, even of those who continue on to sit for A-Levels, less than a quarter (23 percent) is in the science stream, while only a further 10 percent is in the technology stream. The majority (66 percent) are in the arts and commerce streams. Similarly, the distribution of students in public universities is highly skewed towards the arts and social sciences, while the enrolments in the natural sciences are much lower.  


Generating a high share of university graduates, especially in the science, technology, engineering and math (STEM) subjects, is a policy priority for Sri Lanka, given the country’s goal of becoming a knowledge-based economy, driving competition through innovation. The 2018 budget speech correctly identified the need for “improving the ratio of STEM to non-STEM graduates in the country”.  The foundation for STEM education at the graduate level needs to be laid at school level. Only those with a good foundation in general education will move on to tertiary level education, especially in the STEM subjects.


A recent IPS research study highlights the need for good quality teachers for improving the education outcomes of children at O-Levels. A recent complimentary study examines the adequacy of quality teachers to teach science, mathematics and English at secondary level in the country. This article summarizes the main findings of the study.


Surplus of teachers but not enough subject-qualified teachers


According to the 2016 School Census data, Sri Lanka has an overall surplus of teachers, who usually teach mathematics and science subjects; that is, the number of teachers who mostly teach mathematics and science are more than the number recommended by the Education Ministry in the first circular of 2016, on determining the staff numbers in a school.


However, this does not mean that all these teachers are subject qualified. A teacher with either a degree or a specialized training in a particular subject is considered as a subject-qualified teacher. Even though in many countries teachers need to be especially certified to teach a subject, Sri Lanka’s teacher service does not have such a requirement. 


As Figure 1 indicates, the shares of available teachers are more than the recommended number of teachers (over 100 percent), indicative of overall teacher surpluses. Nevertheless, the shares of subject-qualified teachers are much lower than the recommended number of teachers. 
Issues with allocation of teachers


The Education Ministry clearly provides guidelines on the number of teachers recommended for each school, based on the number of classes, availability of subjects and the languages of instruction offered by the schools. However, our analysis shows that some schools have an excess of science and mathematics teachers, while others are sorely lacking in this regard. Our findings also show that more affluent schools, attended by wealthier students, have better teachers than less-advantaged schools.


Unsystematic recruitment of teachers 


Unsystematic teacher recruitment is one reason for the inadequacy of teachers. If the teacher recruitments are properly planned, the number of teachers recruited should roughly match the number of teachers leaving the teacher service. But, an analysis of the School Census data shows that the teacher recruitments are done haphazardly and arbitrarily. In some years, more than 20,000 teachers are recruited, while during other years less than 5,000 teachers are recruited.


Also, the teachers are often not matched to their subject-related education and training at recruitment. As Figure 2 shows, of the total number of science and mathematics teachers joining the teacher service in 2016, only a fraction was subject qualified. Limited pre-service teacher training opportunities


The numbers of teachers trained by pre-service teacher training programmes are not adequate to meet the demand arising for teachers each year. The majority of teachers recruited to the teacher service in Sri Lanka are untrained graduates, followed by those with a National Diploma in Teaching (NDT). 


The untrained graduates have a degree but do not have pedagogical training. Those with the NDT are trained teachers without degrees. This is in contrast to the best practices in other countries. In most countries, a degree and a certificate in specialized teacher training is necessary to become a teacher. 


In Sri Lanka, only those who join the teacher service with a Bachelor of Education (BEd) have both a degree and specialized teacher training. But, the School Census 2016 data show that only a very small share of those joining the teacher service holds a BEd. 


Policy recommendations


There is an urgent need to improve pre-service teacher training, currently offered at the National Colleges of Education and at universities, to match the demand for STEM teachers in schools. Improving and expanding the pre-service training of teachers and giving priority to recruiting teachers with proper pre-service training can help improve the availability of qualified teachers. Such training programmes should especially cater to the demand for teachers in different subject areas. Teacher training should also be well planned to meet the requirements of the teacher service. 


Further, the teachers should be certified to teach different subjects and the subject knowledge of teachers should be taken into consideration when filling vacancies. 


Lastly, the teachers should be allocated to schools according to need, so that no school has an excess of teachers and the teachers are evenly distributed across all schools. Allocating the teacher cadres for schools according to the available classes, subjects and mediums of instructions can prevent schools from recruiting teachers in excess. 


Unless qualified teachers are available in all classrooms, many students like Deepani will not be able to realize their dream of pursuing higher studies in the science and technology field. Unless the students interested in science and mathematics are encouraged from a young age and are given proper guidance, expanding science education at the tertiary level will remain a pipedream.
