The Study On Learning Evaluation Of Mathematics Open-ended Problems In Primary School

The study of mathematics open-ended problems has a positive promoting effect on the thinking development of primary school students.However,how to evaluate the learning quality of primary school students' open-ended problems scientifically and effectively is a major problem that educators are facing in teaching practice.SOLO taxonomy,as a mature evaluation system,can specifically and clearly divide the thinking level of individuals in the process of learning open-ended problems,so that the thinking level of students becomes clear and evaluable.Therefore,this study attempts to construct a learning evaluation tool for primary school mathematics open-ended problems with the help of SOLO taxonomy,modify and establish the tool with delphi method,and analyze the learning quality of open-ended problems for grade 6 students with this tool,so as to help teachers obtain an effective tool for objectively evaluating the learning quality of open-ended problems for students.This study mainly adopts the test method,interview method,case analysis method and other research methods.On the one hand,through referring to relevant literature,the coincidence point of SOLO taxonomy and mathematics open-ended problems is obtained.On the other hand,according to the SOLO taxonomy,a learning evaluation tool for mathematics open-ended problems was constructed.Through tests and interviews,quality analysis was conducted on the responses of grade 6 students,so as to understand the learning level of primary school students' open-ended problems.The results show that the overall learning level of students is at a high level.Students' understanding of open-ended problems is not necessarily in direct proportion to their learning situation;Under different learning tasks,students have different learning levels of open-ended problems.Based on the above research results,this paper puts forward Suggestions.Set up multiple learning tasks to provide students with space for independent development;Combine "quality" and "quantity" to evaluate students' thinking level reasonably.Finally,it can be seen from the study that SOLO taxonomy is feasible to be applied to the learning evaluation of mathematics open-ended problems in primary schools.The evaluation tool based on SOLO taxonomy is scientific to a certain extent,and the evaluation tool of mathematics open-ended problems can effectively measure students' learning level of mathematics open-ended problems.Based on this,this paper reflects on the research and puts forward the prospect of the future research.
