学习兴趣是学生学习的内部动机,是推动学生探求内部真理与获取能力的一种强烈欲望,它在学习活动中起着十分重要的作用。教学实践表明,学生如果对数学知识充满好奇心,对学会知识有自信心,那么他们总是主动积极、心情愉快地进行学习。因此,在数学课堂教学中,我们要时刻注意发掘教材孕育的智力因素,审时度势,把握时机,因势利导地为学生创造良好的教学情境,激发学生的兴趣,让学生在愉快的探索中学习数学。下面结合苏教版第七册“三角形内角和”一课,谈几点体会。 Learning interest is the internal motivation of students ’learning. It is a strong desire to promote students’ inner truth and ability to acquire. It plays a very important role in learning activities. Teaching practice shows that if students are curious about mathematical knowledge and have confidence in learning knowledge, then they always take the initiative to study positively and in good spirits. Therefore, in the classroom teaching of mathematics, we should always pay attention to discovering the intellectual factors that are nurtured by the teaching materials, review the situation, grasp the opportunity, create a good teaching situation for the students to arouse the interest of the students and let the students learn mathematics in a pleasant exploration. The following combination of the Soviet version of the seventh book “triangle angle and ” a lesson, talk about a few experiences.
