一、多媒体辅助教学,激发学习兴趣基于数学学科的特点和小学生的心理特点,兴趣是激发他们学习的最好钥匙。多媒体教学生动形象,声形并茂,能创设有效情景,从而使学生产生浓厚的兴趣。在概念学习中,由于学生的知识水平和所接触的事物都极其有限,学习有一定的困难,学生很难快速掌握概念的本质属性。如在教学《认识方位》时,如果采用传统的教学方式,只是教师的讲解,学生也可能会机械的 First, multimedia-assisted teaching to stimulate interest in learning Based on the characteristics of mathematics and the psychological characteristics of primary school students, interest is to stimulate their learning the best key. Multimedia teaching vivid image, both voice and shape, can create effective scenarios, so that students have a strong interest. In the concept study, because students' knowledge level and the things they touch are extremely limited, learning has some difficulties, and it is difficult for students to quickly grasp the essential attributes of the concept. As in the teaching of “understanding of position”, if the traditional teaching methods, but the teacher's explanation, students may also be mechanical
