Design Research of Mathematical Problem Solving Teaching in Singapore and Its Enlightenment
There are three points worth learning from the study on mathematical problem-solving teaching carried out by mathematical education researchers in Singapore:first,it promotes students'performance in solving unconventional or unfamiliar mathematical problems through mathematical problem-solving teaching;the second is to design,implement and improve the mathematical problem-solving teaching gradually by adopting the design research approach;third,the design of mathematical problem-solving teaching mainly revolves around the process(including heuristics)of mathematical problem solving.However,there are two main shortcomings of this study:first,the design of mathematical problem-solving teaching lacks a theoretical basis to guide the design;second,the design principles of mathematical problem-solving teaching are not fully refined.
