The Designjng And Evaluation Of Junior Middle School Math Teaching Open-Ended Problems

Math exercises are very important parts of math learning, whether wecan select proper exercises can directly influence the quality of students learning math, the development of students' intelligence and cultivation of their ability,, In the past ten years, the circles of Chinese middle school math teaching all attach importance to problem-solving Achievements in problem-solving research are quite considerable,. However, we have to notice that quite a few middle school teachers have forgotten "solving math exercises problems" itself is not a goal, but a training means They neither take problem-solving as the chance to cultivate students' ability to be creative, nor treat problem-solving in a right way And this results in students' high ability to solve math problems but low ability to do manual work and to be creative and it is hard to integrate theory with practice and solve practical problems creatively.. This is the problem which needs solving currently., The introduction of open-ended mathematical problems is an effective measure to correct and remedy the defect The center of quality-centered education is creative spirit, the value of open-ended mathematical problem focuses on cultivating students' spirit and ability to be creative Therefore open-ended mathematical problems help promote the quality-centered education Today, more and more math educators and teachers home and abroad pay close attention to open-ended mathematical problems Domestically, there are two main problems: One is how to reflect its educational value by designing open-ended problems, the other is how to evaluate., open-ended problem more reasonably by setting a series of appropriate standards., But special research on the two problems is very little and effective ways are few The thesis embodies the educational value of open-ended problem to the most by beginning with classifications of open-ended problem and designing open-ended problem.,Guided by the ideas of new evaluation , the thesis not only inquires into the hottest issues of open-ended problem evaluation like class evaluation, test evaluation, homework evaluation, but also does some deep research about quick ways of improving results and recording bags of open-ended problem evaluation This thesis is expected to be able to guide open-ended problem teaching theoretically in some certain way, therefore it can develop creative thought of students of different levels and enable open-ended problem teaching to be more effective..
