Study Notes
Effectiveness of Shift-Problem Lessons
- Seventh-grade students engaged in shift-problem lessons on early algebra showed more and qualitatively better mathematical discussions compared to conventional textbook lessons.
- The most frequent activity observed in discussions was "tell/show work", which was of better quality in the shift-problem condition.
Areas for Improvement
- There is a need for improvement, as most activities involved telling and showing work, rather than deeper understanding and critical thinking.
- To enhance the quality of discussions, activities should be designed to encourage explaining, justifying, and reconstruction.
Impact on Students' Mathematical Levels
- Students' mathematical levels improved in both lesson conditions, however, multilevel analyses did not reveal significant differences between the two conditions.
