在课堂教学中,教师根据儿童的年龄特点和认知特征,巧用电教手段,创设一个能激起学生积极思维的愉悦情境,使学生参与知识的形成过程,激发对数学的学习兴趣,这就能够有效地提高数学教学的效果和质量。现根据数学课的特点,就如何利用投影来创设数学学习的愉悦情境,谈几点做法和体会。一、设疑激趣,使学生愿意学。小学生好奇心强,对新奇的东西容易产生兴趣。教师教学时,要根据教材特点有意设置悬念,利用投影,巧布疑阵,创造诱人的学习环境,引起学生的好奇心,并使这种好奇心转化为求知欲,进而转移到新知识的学习上去。
In classroom teaching, teachers, based on the age characteristics and cognitive characteristics of children, make use of the means of audio-visual education to create a pleasant situation that can arouse students’ positive thinking, enable students to participate in the formation of knowledge and stimulate their interest in learning mathematics Can effectively improve the effectiveness and quality of mathematics teaching. Now based on the characteristics of math class, how to use the projection to create a pleasant situation in math learning, talk a few practices and experience. First, suppose doubts, so that students are willing to learn. Pupils are very curious and tend to be interested in new things. Teachers teaching, according to the characteristics of teaching materials intended to set suspense, the use of projection, Qiaopu doubt array to create attractive learning environment, arouse the curiosity of students, and make this curiosity into curiosity, and then transferred to new knowledge learning Go up.
