对初中数学教学建构主义成分与维度的评估——基于教师反思的视角

为了考察建构主义思潮对课堂教学的影响,对初中数学教师进行了调查.结果表明,教师在帮助学生进行认知建构时更多关注学科层面,更少关注学生层面;在促进学生开展社会建构时更多倾向于师生交往,更少关注学生之间的合作;在为建构主义教学创造条件时努力关注数学与现实的联系,并满足学生的需要,但课程意识却非常淡薄.这折射出教师的教学观念发生了期望中的变化,但要完全服务于学生的建构学习,还有很长的路要走.

The Evaluation of Mathematics Teaching in Junior Middle School at the Composition and Dimensionality of Constructivism

In order to investigate the trend of constructivist over classroom teaching, a survey of junior mathematics teachers was made. The results showed that teachers pay more attention to the subject instead of students＇ cognitive level when help students build their cognitive-structure; more inclined to teacher-student interactions, fewer considered the cooperation among students when promote the students＇ social constructs ; concerns the contact with reality to meet the cognitive needs of students when creating the conditions of constructivist teaching, while teachers＇ course sense was still weak. This showed that the basic concept of teachers＇ classroom teaching has changed as expected, but if we want to fully serve the students in the construction of learning, there is still a long way to go.
