生物学是一门实验性很强的自然科学。因此教师在讲授基本知识的同时,让学生及时看到所研究对象的形态、结构及生理活动,是使学生迅速而准确掌握生物学知识必须的。帮助学生系统掌握基本知识的直观教学手段内容颇多,其中板画教学简便易行,不受时间、地点的约束和限制,避免学生盲目观察对象。下面就我在生物教学过程中怎样运用板画,谈谈粗浅看法:一、课堂上边讲边画能集中学生的注意力,同时便于学生系统掌握生物学知识。
Biology is a highly experimental natural science. Therefore, when teachers teach basic knowledge, it is imperative for students to timely see the shape, structure and physiological activities of the subject under study so that students can quickly and accurately grasp the biological knowledge. To help students master the basic knowledge of intuitive teaching methods, there are many contents, including drawing ease of teaching, free from time and place constraints and restrictions to prevent students blindly observe the object. The following on how I use the boarding process in the biological teaching, to talk about the superficial view: First, the class edge painting can focus on the attention of students, while allowing students to systematically grasp the biological knowledge.
