The document summarizes Roslinda Rosli's dissertation defense on integrating problem posing in teaching and learning mathematics. It provides an overview of the dissertation and introduces the research questions and methodology used in four studies on the effects of problem posing on student learning, preservice teachers' problem solving and posing abilities, and preservice teachers' knowledge and attitudes towards fractions. The theoretical framework draws on constructivist learning theory. Key findings include that problem posing can benefit student mathematics learning, and preservice teachers demonstrated understanding in solving mathematical problems but posed many low-quality problems initially.

Overview ▪ Introduction ▪ The effects of problem posing on student learning: A meta analysis ▪ Middle grade preservice teachers’ mathematical problem solving and problem posing ▪ A mixed research study of elementary preservice teachers’ knowledge and attitudes towards fractions ▪ Summary and conclusions 2
- 3. Why on problem posing? (Chapter 1) • Students of all ages, including those who subsequently become teachers, have limited experience in problem posing (Crespo & Sinclair, 2008). • Preservice and inservice teachers posed many low quality mathematical problems (Silver, Mamona-Downs, Leung, & Kenney, 1996). 3

- 6. Theoretical Framework • Constructivist learning theory (von Glasersfeld, 1989). • The openness feature of the problem posing tasks can reveal how an individual learns mathematics (Kulm, 1994). 6
- 7. The effects of problem posing on student learning: A meta analysis (Chapter 2) 7
- 9. Chapter 3:Middle grade preservice teachers’ mathematical problem solving and problem posing 9 •The results from previous studies were mixed suggesting a complex relationship between problem solving and problem posing success (Cai & Hwang, 2002;Chen, Can Dooren,Qi, &Verschaffel, 2010). Research Questions 1) How do select middle grade preservice teachers solve a block pattern task before or after posing mathematical problems? 2) How do select middle grade preservice teachers pose mathematical problems before or after solving a block pattern task? 3) What is the relationship between select middle grades preservice teachers’ problem solving and problem posing? 4) What are select middle grades preservice teachers’ perceptions and concerns when posing mathematical problems?
- 10. ▪ Participants: 51 middle school preservice teachers in a problem solving course. ▪ Instrument: A pair of problem solving and problem posing task -The Block Pattern Problem (Cai & Lester, 2005). ▪ Additional data: Group presentation of the homework problems, two open-ended questions on problem posing task. ▪ Procedures: ▪ Data analysis: – Rubrics according to performance indicators 1 (unsatisfactory) through 4 points (extended). – Inter-rater agreement: 73-87% – Descriptive statistics, Mann-Whitney test, Spearman’s Rho, constant comparison analysis Method 10 Group A (n=25) Problem Solving Problem Posing Group B (n=26) Problem Posing Problem Solving
- 11. Results 11 • Solving the Block PatternTask • 70% of preservice teachers showed their understanding in finding the number of blocks to build a staircase of 6 steps and 20 steps.

Editor's Notes
- #5: Many of these studies present positive outcome of problem posing on students’ knowledge, problem solving and problem posing skills, creativity, and disposition toward mathematics.
- #7: -knowledge is not passively received but actively built up by the cognizing subject; the function of cognition is adaptive and serves the organization of experiential world, not the discovery of ontological reality-students construct their own understanding while posing problems.
- #11: Hypotheses: Participants in group A (solved first) had a greater capacity to generate new problems. Group B (posed first) performed better on the problem solving task.
