为了使学生既掌握生物的基础知识和基本技能,又能够不断地提高分析问题和解决问题的能力,在生物教学中如何处理好教与学、讲与练、知识和能力三方面的关系,就成为生物教学中需要认真探索的问题之一。本学期,在领导和教研组的关心、帮助下,我在初一植物《叶的光合作用》一节的教学中,就上述问题作了一些尝试。认识在过去的教学中,我只是按照教材的顺序,首先交待光合作用的概念,之后按照教材的要求演示验证光合作用的几个实验,最后再进一步讲述光合作用的实质、意义等内容。通过对教学大纲和教材的深入学习研究,在“引导发现法”教学经验的启发下,看到过去的教学程序在培养学生能力、调动学生学习积极性和主动性等方面,都还存在着一定的不足。生物科学是一门实验性很强的科学,生物科学中的一些重大发现,一些规律和结论的得出都建立在广泛科学实验的基础上。在生物教学中如何体现生物科学的这一特点呢?我们研究后决定运用“引导发现法”。首先提出问题,之后引导学生实验观察进行探索,最后通过对
In order to make students not only master the basic knowledge and basic skills of biology, but also constantly improve the ability to analyze and solve problems and how to handle the relationship between teaching and learning, speaking and practicing, knowledge and ability in biology teaching Become one of the problems that need to be seriously explored in biology teaching. This semester, with the care and help of leaders and teaching and research groups, I made some attempts on the above issues during the teaching of the first leaf photosynthesis in plants. Recognition In the past teaching, I just explained the concept of photosynthesis according to the order of teaching materials, and then demonstrated several experiments of photosynthesis according to the requirements of teaching materials. Finally, I further narrated the essence and meaning of photosynthesis. Inspired by the teaching experience of “Guiding the Discovery Law” through the in-depth study and study of the syllabus and teaching materials, we can see that there are still some teaching procedures in the past in terms of cultivating students’ abilities and arousing the enthusiasm and initiative of students. insufficient. Biological science is a very experimental science, some of the major discoveries in the biological sciences, some of the laws and conclusions are based on a wide range of scientific experiments. How to embody this feature of biological science in biology teaching? After studying, we decided to use the “guide-finding method”. First ask questions, then guide students to explore the experimental observations, and finally passed
