布卢姆的掌握性学习理论认为,为了有效地进行教学,首先应知道通过教学应达到的目标是什么。目标教学就是设计教学目标,即教师应知道对所教的内容在各个领域内要求学生掌握到什么程度,并围绕目标选择适当的教学方法并通过反馈—矫正系统使学生达到目标。一、根据知识结构,确定教学目标本章共分为5节,另有2个实验。就基础知识而言,包括3部分内容;一是叶的形态与结构;二是叶的生理功能(光合作用,呼吸作用,蒸腾作用)和这些的知识在实践中的应用;三是生态环境对叶的影响。以上3部分内容在教学中有不同的要求,如果从教学目标上看,可从以下3个领域进行确定。
Bloom’s theory of mastered learning argues that in order to teach effectively, one must first know what the goal is to achieve through teaching. Goal teaching is to design teaching goals, that is, teachers should know what level of content the students are required to teach in various fields, and select appropriate teaching methods around the goal and use the feedback-correction system to achieve students’ goals. First, according to the knowledge structure, determine the teaching objectives This chapter is divided into five sections, and another two experiments. In terms of basic knowledge, it includes three parts: one is the shape and structure of the leaf; the second is the physiological function of leaves (photosynthesis, respiration, transpiration) and the application of these knowledge in practice; the third is the ecological environment. Leaf effect. The above three parts have different requirements in teaching. If you look at the teaching objectives, you can determine from the following three areas.
