一、联系生活实际布鲁纳曾说过:使学生对一门学科有兴趣的最好办法是势必使之知道这门学科是值得学习的。在我们的生活环境中,有多样的生物和多种与生物学知识相关联的问题,因此,联系生活实际对于我们生物学科来说变得较为容易。比如,在教授细胞呼吸这节内容时,我事先准备了红葡萄酒和面包,在学生理解了有氧呼吸和无氧呼吸两种呼吸类型以后,让学生根据刚才学到的知识来解释这两种均由酵母菌来发酵的产物。学生们看到老师拿来的葡萄酒和面包兴致很高涨,对于我提出的问题也特别感兴趣。而学生通过讨论,他们利用刚学到的无氧呼吸知识来解释葡萄酒的制作,又
I. CONNECTING LIFE ACTUAL Bruner once said that the best way for students to be interested in a subject is to make sure that the subject is worth learning. In our living environment, there are diverse creatures and a variety of issues associated with biological knowledge, so it is easier for our biology to relate to the reality of life. For example, when teaching a cell to breathe this section, I prepared red wine and bread in advance. After the students understood both types of breathing, aerobic and anaerobic respiration, students should interpret the two according to what they have just learned Yeast to ferment the product. The students were very excited to see the wine and bread brought up by the teachers and were particularly interested in the issues I raised. Through discussion, students use the oxygen-respiration knowledge they just learned to explain the production of wine.
