小学常识学科内容包罗万象、但是小学生年龄小。阅历浅,如果单凭教师口头讲解,学生不易听懂或不愿听。近年来,我运用投影媒体,优化课堂教学结构,激发学生学习常识课的兴趣,从而提高了课堂教学效果。吸引学生的注意力因为小学常识中的很多课文是介绍自然界的物质和人们常见的自然现象,所以,在每节课中,教师都必须指导学生去观察自然界中的事物和现象,为形成自然科学的有关概念提供生动、具体的感性材料。为此,上这一类课文时,我总是以放有关的投影片作 Common sense in primary school Discipline content, but primary school age. Experience shallow, if the teacher alone verbal explanation, the students do not understand or do not want to hear. In recent years, I have used projection media to optimize the classroom teaching structure and stimulate students’ interest in learning common sense lessons, thereby enhancing the effectiveness of classroom teaching. Attracting Students’ Attention Because many texts in primary school common sense are objects that introduce nature’s material and people’s common natural phenomena, in each lesson, teachers must instruct students to observe things and phenomena in nature and create natural science The concept of providing vivid, specific sensuous material. For this reason, I always put relevant projection films on this type of text
