生物学是一门以实验为基础的学科,以实验为载体创设的学习支架在生物学学习中具有重要价值。笔者以苏科版生物学教材(八年级上册)中“蒸腾作用”概念教学为例,谈谈如何通过搭建实验支架来帮助学生形成生物学概念。一、运用实验支架的可行性分析概念是人们在感知的基础上经过抽象概括形成的,具有高度浓缩的特征。教师应该将概念这一浓缩物稀释,尽可能地还原其本来面目,从而抓住其中的关键要素,搭建合乎知识逻辑的学习支架,让学生沿 Biology is an experiment-based discipline. Learning scaffolds based on experiments are of great value in biology learning. The author uses the concept of “transpiration” in the teaching of Su Ke edition biology textbook (Grade 8) as an example to talk about how to help students form a biological concept through the construction of experimental stents. First, the feasibility analysis of the use of experimental scaffolding concept is based on the perception of people through the abstract summary of the formation of highly concentrated features. Teachers should dilute the concept of this concentrate, as far as possible to restore its true colors, so as to seize the key elements of which, in accordance with the logic of learning to build learning support, so that students along
