表现性评价是通过客观测验以外的行动、表演、展示、操作、写作等更真实的表现来评价学生口头表达能力、文字表达能力、思维能力、创造能力、实践能力的评价方法。我校的表现性评价一般在学期结束时进行,策划一些有趣的活动,让学生在参与过程中运用数学的知识解决问题,老师通过观察其语言表达、方法选择、运用效果等用等级制进行评价。随着学习的深入,尤其是《小学低年级数学学科基于课程标准评价指南》让老师们对基于课程标准的表现性评价也开始有 Performance evaluation is to evaluate students’ verbal ability, expressive ability, thinking ability, creative ability and practical ability through more realistic performance such as action, performance, display, operation and writing besides objective test. The performance evaluation of our school is usually carried out at the end of the semester. Some interesting activities are planned to help students solve the problem by using mathematical knowledge in the process of participation. The teacher evaluates the students by observing their language expression, choice of methods and effectiveness . With the deepening of learning, especially the “Guidelines for Evaluation of Mathematics Standards Based on Curriculum Criteria in the Lower Primary Schools of Primary School”, teachers also started to have performance evaluations based on curriculum standards
