人类吸收知识、捕获信息,主要依靠视觉器官和听觉器官,尤其是视觉器官所吸收和捕获的信息,占人所获得的信息总量的83%。我根据人体吸收信息的这一特点,在生物课教学中采用边讲边画的方法进行讲解,效果比较好,特别是讲到一些重点、难点的内容,一边讲解一边画图,很受学生的欢迎。例如:在讲述人体血液循环一节时,我先画一个心脏模式图,然后在左心室上连主动脉,右心房上连上、下腔静脉,在右心室上连肺动脉,在左心房
Human absorption of knowledge, capture information, mainly rely on visual and auditory organs, especially visual organs to absorb and capture the information, accounting for 83% of the total information obtained. According to the characteristics of the human body to absorb information, I used the method of speaking and painting in the teaching of biology to explain the effect better, especially when it comes to some important and difficult contents. While drawing on the drawing, I was greatly welcomed by the students . For example, in a section on human blood circulation, I first plotted a pattern of the heart, then connected the aorta to the left ventricle, to the right atrium, to the inferior vena cava, to the pulmonary artery in the right ventricle, to the left atrium
