随着课程改革的不断深入,学生的数学素养普遍得到提高。但在不少农村基层学校,还有相当部分教师的课堂互动方式过于单调呆板,一节课下来基本上都是采用最简单的方式——教师和学生群体互动进行教学,即教师演示、提问和学生集体回答的方式,导致课堂气氛沉闷,教学效率低下。教师和学生群体互动的方式虽然方便省时,面向全体学生,但它也有自身的局限性,即不利于学生的思考,忽视对学生个体的关注,容易导致学生产生厌学情绪,最终影响教学效果。就目前农村学校的课堂教学来看,这种现象相当普 With the continuous deepening of curriculum reform, students’ mathematics literacy has been generally improved. However, in many rural grass-roots schools, there are still quite a few teachers whose classes are too monotonous in class. Basically, the most simple method is used in one lesson - interaction between teachers and student groups for teaching, that is, teacher demonstration, questioning and The way students collectively answer, resulting in a dull classroom atmosphere, inefficient teaching. Although the way of interaction between teachers and student groups is convenient and time-saving for all students, it also has its own limitations, which is not conducive to students’ thinking, ignoring the individual attention of students, easily lead to students tired of learning, and ultimately affect the teaching effectiveness . In the current rural school classroom teaching, this phenomenon is quite general
