Summary of "Strengthening Science Education in Sri Lanka" (Report No. 45, August 2011)

Core Content

This report evaluates the state of science education in Sri Lanka, highlighting both progress and challenges. It outlines the need for further reforms to improve scientific literacy, which is essential for innovation and development in a knowledge-driven global economy. The study focuses on learning achievements, policy initiatives, curriculum reforms, and the role of teacher training and assessment systems in shaping science education outcomes.

Main Views

• Scientific Literacy and Education Quality: Scientific literacy is crucial for knowledge generation and innovation. A quality science education is key to achieving this, but current outcomes are not meeting expectations, particularly in applying knowledge to real-life situations and the workplace.

• Learning Achievements:

  • National cognitive achievement tests in science at Grade 8 show improvement in learning outcomes from 2005 to 2008, with a national mean score rising from 53.2% to 56.3%.
  • Female students outperformed male students in both 2005 and 2008, with mean scores of 56.6% and 56.0% respectively.
  • Rural schools showed greater improvement in science learning outcomes compared to urban schools, with the gap between the two sectors reducing from 5% to 3%.
  • There is a significant disparity in science performance across school types, with type 1AB schools leading, followed by type 1C, and type 2 schools lagging.
  • Sub-skills such as comprehension, knowledge, analysis, application, and synthesis have all shown improvement, but synthesis remains the weakest, possibly due to limited real-world application and lack of experimental learning.

• GCE O/L and A/L Examinations:

  • GCE O/L pass rates in science declined from 55% in 2002 to 48% in 2009, despite stable mean scores.
  • There is a large variation in pass rates across provinces, with the Western Province leading at 73% and the Uva Province lagging at 41%.
  • National schools outperformed provincial schools in GCE O/L results, with a 32% difference in pass rates.
  • In the GCE A/L biological science stream, biology pass rates remained relatively constant at 74% (2009), while physics and chemistry pass rates increased, indicating a positive trend.

Key Information

• Curriculum and Teaching Methods:

  • A competency-based curriculum was introduced in 2007, emphasizing student-directed inquiry and practical skills.
  • However, the curriculum still places a heavy emphasis on content delivery, and the teaching methods are not fully aligned with the competency-based approach.
  • Teachers are not adequately supported in integrating practical work and diverse teaching strategies, which are essential for effective science learning.

• Teacher Training and Availability:

  • There is a shortage of science teachers, particularly in rural areas.
  • Teacher quality varies, with a need for more subject-specific training in both theory and practical work.
  • The report suggests upgrading one of the National Colleges of Education (NCOEs) to a National Centre for Excellence in Science Teaching.

• Assessment and Examinations:

  • Examinations need to be aligned with the competency-based curriculum to accurately measure learning outcomes.
  • The 5E learning model (Engage, Explore, Explain, Elaborate, Evaluate) is recommended but not widely adopted due to time constraints and heavy syllabi.
  • The GCE A/L examination based on the new science syllabus will be held in August 2011.

• ICT Integration:

  • Information and Communication Technologies (ICT) can enhance science education by making it dynamic and interactive.
  • The 'schoolnet' digital network, which connects over 300 schools, has potential to support science education but is not yet fully utilized.

• Recommendations:

  • Develop a clear science education policy aligned with the National Science and Technology Policy.
  • Review and reduce the content of the science curriculum to avoid overload.
  • Promote practical work and experiments in science education.
  • Improve teacher training and address shortages, particularly in rural areas.
  • Enhance the use of ICT in science education.
  • Integrate international assessments like TIMSS and PISA to benchmark performance.
  • Encourage research-based approaches to policy formulation and implementation.

Conclusion

The report underscores the importance of science education in building a scientifically literate population and driving economic growth. While progress has been made, significant gaps remain in achievement levels, teacher quality, and practical learning. A comprehensive, research-based approach is necessary to address these issues and ensure equitable and effective science education across all sectors and regions of Sri Lanka.
