教师以“直观教学”为中心理念进行课堂设计,践行了现代生物教学的理念,利用教具给予学生直观的感受,帮助学生对一些跨学科的知识、动态变化的连续过程、三维立体的结构有更好的理解,锻炼了学生动手操作能力,使课堂更加生动有趣。这种课堂设计有利于教师突出教学重点和突破教学难点,从而使教学效果达到最佳化。本文以高中生物课程——“蛋白质”为例,以此体现直观教学对优化课堂设计的重要性。
Teachers focus on the concept of “Intuitive teaching ”, carry out the classroom design, implement the concept of modern biological teaching, use the teaching aids to give students an intuitive feeling, and help students to interdisciplinary knowledge, the dynamic process of continuous change, three-dimensional The structure has a better understanding, exercise the students ability to operate, make the class more lively and interesting. This classroom design is conducive to teachers highlighting the teaching focus and breakthrough teaching difficulties, so that teaching effectiveness can be optimized. In this paper, the high school biology curriculum - “protein ” as an example, in order to reflect the importance of visual teaching to optimize classroom design.
