当前中学数学对学生解答题的评价是一个结果性评价,且有一个满分的限制(高考评价也是如此),而忽略了对学生做题过程中思维的创新性、过程的简洁性、算法的合理性这些更为本质的评价.这一评价方式的结果是:学生做题只管结果而不重过程,只管得分而不反思思维、策略中的智慧与创新.长此以往,学生只有读死书、死读书、成了做题的机器、得分的高手.如何改变这一局面呢?经研究,我将数学题的解答分为问题空间、策略空间、推理运算空间,在每一空间中设有错误、正确、
The current middle school mathematics evaluation of student questions is a result evaluation, and there is a limit of full marks (also the evaluation of the college entrance examination), while ignoring the creativity of the students in the process of doing questions, the simplicity of the process, the algorithm is reasonable These more fundamental assessments of sex. The result of this evaluation method is that students do not rely on the results only to repeat the process, but instead of reflecting on the thinking, the wisdom and innovation in the strategy. In the long run, students can only read books and die. , has become a problem machine, the master of scoring. How to change this situation? After research, I will solve the math problem is divided into problem space, strategy space, reasoning computing space, with error in each space, correct ,
