传统的课堂教学对学生的参与重视不足,常常是教师枯燥的讲授,学生被动的接受,强制性地对所学公式、解题方法进行记忆,然后通过大量的习题训练和针对性考试并就题讲题进行强化.随着多媒体教学手段的日益丰富,以及对学生全面能力的培养,学生参与课堂教学、融入课堂已成为教学中的一个重点.因此,培养学生对课堂的参与意识,构建一个高效的数学课堂,是高中数学老师的当务之急. Traditional classroom teaching lacks emphasis on students’ participation. It is often boring teaching of teachers. Students passively accept and comprehend the formulas and problem-solving methods compulsorily, and then pass a large number of exercises and targeted examinations. With the enrichment of multimedia teaching methods, as well as the cultivation of students ’comprehensive ability, the students participate in the classroom teaching, into the classroom has become a focus of teaching.Therefore, to cultivate students’ sense of participation in the classroom, to build an efficient Math class, is a high school mathematics teacher’s top priority.
