Summary of Inside Indonesia's Mathematics Classrooms: A TIMSS Video Study of Teaching Practices and Student Achievement

Core Content

This report presents the findings of a video study conducted in Indonesia as part of the TIMSS (Trends in International Mathematics and Science Study) initiative, focusing on teaching practices and student achievement in mathematics classrooms. The study analyzed 100 classes from the 2007 TIMSS examination and aimed to understand how teaching methods and classroom environments influence student performance. It also serves as a foundation for future analysis involving the 2011 TIMSS exam.

The study was a joint effort between the World Bank and the Indonesian Ministry of National Education (MONE), with insights from international experts and a structured methodology based on previous TIMSS video studies from seven countries.

Main Findings

1. Classroom Structure and Duration

• Lesson Duration: Indonesian mathematics lessons were significantly longer (70 minutes) compared to comparator countries (average 51 minutes), but this did not result in more weekly mathematics hours.
• Time Allocation:
  • Mathematics Time: 89% of lesson time was dedicated to mathematics, compared to 96% in other countries.
  • Non-mathematics Time: 3% of time was spent on non-mathematical activities.
  • Mathematics Organization Time: 8% of time was used for organizational tasks.
• Problem vs. Non-problem Time:
  • Only 76% of mathematics time was spent on problem-solving, while other countries allocated 81%–96%.
  • Indonesia had fewer independent problems (3.3 per lesson) compared to other countries (3–13).
  • However, Indonesia spent more time per problem (6.6 minutes) than most other countries (3–5 minutes).
• Purpose of Lesson Segments:
  • Practice: 37% of mathematics time was dedicated to practice, higher than the 16%–37% range in other countries.
  • New Content Introduction: 43% of time was spent on this, compared to 22%–60% in other countries.
  • Review: Only 10% of time was used for reviewing previous content, much less than the 24%–58% in other countries.
  • Assessment: Not explicitly mentioned in the summary, but part of the overall lesson structure.

2. Lesson Content and Complexity

• Problem Complexity: Only 3% of problems in Indonesian classrooms were of high complexity, compared to 6%–39% in other countries.
• Problem Types:
  • Applications: Fewer problems involved real-world applications.
  • Proofs: More problems included proofs, indicating a focus on theoretical understanding.
• Solution Methods: The use of alternative solution methods was limited, with few students exposed to different problem-solving approaches.

3. Instructional Practices and Teacher-Student Interaction

• Teaching Strategies:
  • Exposition: 52% of lesson time was spent on exposition (teacher explaining, students listening and answering closed questions).
  • Problem-Solving: 20% of time.
  • Discussion: 15%.
  • Practical Work and Investigation: 10% and 3%, respectively.
• Mathematical Processes:
  • Stating Concepts: 35% of problems involved stating concepts, higher than comparator countries (5%–24%).
  • Using Procedures: 41%, lower than most other countries (41%–84%).
  • Making Connections: Not explicitly mentioned in the summary.
• Verbal Interaction:
  • Teachers spoke fewer words (2,633) compared to other countries (5,198–5,902).
  • Students spoke fewer words (194) compared to other countries (640–1,108).
  • Teacher-to-Student Ratio: 28:1, much higher than the 8–16 ratio in other countries.
  • This suggests limited student participation and engagement.

4. Classroom Climate and Resources

• Classroom Environment: Generally conducive to learning, with few outside interruptions.
• Resources:
  • Projectors: Used in 9% of classes.
  • Calculators: Used in 13% of classes.
  • Textbooks: Used in 93% of classes.
  • Real-world Objects: Used in 28% of classes, higher than comparator countries (4%–21%).

5. Lesson Signature

• The "Lesson Signature" is a pattern of classroom activities derived from the video study.
• Public vs. Private Interaction:
  • Public (Full-class): 57% of time, dominated by teacher lectures (59%).
  • Private (Small-group or individual): 43% of time, with 55% spent on small-group work and 45% on individual work.
• Segmentation:
  • Introduction: Review of previous homework.
  • Development: Introduction of new content, with questions to assess prerequisite knowledge.
  • Closing: Summaries, often involving student participation.

Key Implications

• Teacher Background:
  • Teacher education levels and certification were important factors in the study.
  • The requirement for a four-year degree and certification by 2015 was a major reform effort.
• Teaching Practices:
  • Exposition was the dominant strategy, but there was potential for greater use of problem-solving and discussion.
  • Limited use of real-world applications and alternative solution methods may hinder deeper understanding.
• Student Engagement:
  • Lower verbal interaction between teachers and students suggests limited student engagement.
  • However, some classrooms showed high engagement without frequent verbal participation.
• Policy Recommendations:
  • Enhance teacher training to promote more interactive and problem-solving oriented teaching.
  • Encourage the use of diverse teaching strategies and real-world applications.
  • Improve classroom resources and support for student-centered learning.
  • Focus on teacher beliefs and subject content knowledge to influence teaching effectiveness.

Conclusion

The video study provides a detailed insight into the structure, content, and practices of Indonesian mathematics classrooms. It highlights both strengths and areas for improvement in teaching and learning. The findings support the need for policy reforms and teacher training to enhance student achievement and engagement in mathematics education.
