Summary of "Strengthening Mathematics Education in Sri Lanka" (Report No. 43, July 2011)

Core Content

This report evaluates the current state of mathematics education in Sri Lanka, focusing on learning achievements, curriculum reforms, teaching strategies, and future pathways. It highlights the importance of mathematics education in developing analytical and problem-solving skills essential for both scientific and everyday life contexts. The findings are based on data from national assessments, GCE O/L and A/L examinations, and insights from education policy and curriculum development.

Main Views

• Mathematics is crucial for modern society, as it equips students with the skills needed for expert thinking, non-routine problem solving, and effective decision-making.
• Progress in learning outcomes has been observed in Grade 8 students from 2005 to 2008, with both urban and rural schools showing improvement, though disparities remain.
• Gender differences are noted, with girls showing a slightly greater increase in scores than boys.
• School type significantly influences performance, with Type 1AB schools (better funded and larger) performing better than Type 1C and Type 2 schools, which serve a majority of students from disadvantaged communities.
• Sub-skills in mathematics have seen improvements, with communication and problem-solving being the strongest, while reasoning remains the weakest.
• GCE O/L pass rates have increased from 44% to 51% between 2005 and 2009, but the mean score remains low, suggesting that the system is not effectively preparing students for higher-level mathematics.
• GCE A/L performance in mathematics is lower than in other subjects like biology, and the number of students offering mathematics has not increased significantly in recent years.
• Curriculum reforms since the 1990s have aimed to align with international standards, but implementation has faced challenges, including lack of flexibility and support for teachers.

Key Information

Learning Achievements

• Grade 8 National Assessment (NEREC):

  • Mean score increased from 45.2% in 2005 to 50.4% in 2008.
  • Female mean score increased from 45.9% to 51.6%.
  • Male mean score increased from 44.4% to 49.2%.
  • The improvement is statistically significant at 99%.
  • The gap between urban and rural students reduced from 8% to 4%.
  • Type 1AB schools had the highest mean scores (56.0% to 58.4%), while Type 2 schools showed minimal improvement (42.9% to 43.1%).

• GCE O/L Examination:

  • Pass rates increased from 44% in 2005 to 51% in 2009.
  • In 2009, 49% of O/L students qualified for A/L.
  • The mean score for O/L mathematics was consistently low (around 32%).
  • Regional disparities exist, with the Western Province having the highest pass rate (60%) and the Uva and North Central provinces the lowest (42%).

• GCE A/L Examination:

  • Combined mathematics pass rate was 44.9% in 2009.
  • Only 600 schools offer GCE A/L mathematics, which is about 25% of all schools with A/L classes.
  • The number of students offering mathematics has not increased over the past six years, and pass rates have shown a declining trend.

Curriculum and Teaching Strategy

• National Education Policy:

  • Established in 1991 by the National Education Commission (NEC).
  • Curriculum reforms in 1997 and 2007 aimed to improve application of knowledge in real-world situations.
  • The reforms introduced a competency-based learning model, but implementation has been inconsistent.

• Primary Education (Grades 1 to 5):

  • An integrated curriculum was introduced, emphasizing child-centered learning and guided play.
  • Mathematics Teacher's Instructional Manuals (TIMs) outline 10 common competencies, entry-level skills, and learning methodologies.
  • Textbooks are aligned with TIMs, but many contain errors.

• Junior Secondary Education (Grades 6 to 11):

  • The curriculum includes 31 common competencies and aims for international alignment.
  • TIMs focus mainly on basic concepts and skills, lacking opportunities for open-ended and creative problem-solving.
  • Teachers are restricted to using only the prescribed activities, limiting their flexibility.

• Senior Secondary Education (GCE A/L, Grades 12 to 13):

  • Only 600 schools offer mathematics and science streams.
  • Three mathematics courses are available: combined mathematics, higher mathematics, and pure mathematics.
  • The 5E learning model is advocated, but most teachers use traditional lecture methods.
  • Textbooks are not provided by the government, though the EPD has translated some international materials.

Pathways for Improvement

• Curriculum Design:

  • A differentiated curriculum should be considered, with two options: one for students pursuing math-intensive subjects and another for general education.
  • Competency-based learning needs to be more clearly integrated into TIMs and teaching strategies.

• Teacher Development:

  • A comprehensive teacher training program is essential to improve subject knowledge and teaching practices.
  • Teachers should be trained to use a variety of strategies and to adapt to student needs and time constraints.

• Textbook Quality:

  • The EPD should invest in hiring qualified writers to produce accurate and aligned textbooks.
  • Textbooks should be evaluated by at least two subject experts to ensure quality.

• Assessment and Monitoring:

  • A systematic monitoring program is needed to evaluate the effectiveness of the curriculum and identify areas for improvement.
  • Clear guidelines for assessing process standards such as reasoning and problem-solving should be developed.

• Resource Allocation:

  • Efforts should be made to improve education services in disadvantaged provinces and rural areas.
  • ICT integration and horizontal subject integration should be encouraged to enhance learning outcomes.

Conclusion

While Sri Lanka has made progress in improving mathematics education, significant challenges remain. These include regional disparities, low mean scores, lack of teacher training, and insufficient curriculum flexibility. Future reforms should focus on differentiated curricula, teacher development, textbook quality, and ongoing monitoring to ensure that mathematics education meets the needs of all students and prepares them for the demands of the modern world.
