“建立血糖调节模型”的教学设计与组织策略

“Establishing glucose regulation model” instructional design and organizational strategy

在高中生物教学中,血糖平衡的调节一直是重要的教学内容。以往的教学设计思路主要是依靠教师讲述,学生被动接受,因此学生在学习上缺乏主动性。且由于内容比较抽象,学生很难真正理解。教师如何依据现代教育理论,通过组织和引导学生模拟血糖的调节机制,建构和不断修正动态的物理模型,再建构抽象的血糖调节的图解式概念模型,从而使学生深入理解血糖调节的机制,更好地理解体内激素对生命活动进行的调节,不仅是突破教学难点有效途径,对学生建立科学思维方式也具有重要的意义。结合课堂教学实际,介绍"建立血糖调节模型"的教学设计和"概念模型"的教学组织策略两个方面研究成果。

Summary In biology teaching of senior high school, the regulation of blood sugar balance has always been an important teaching point.Previously, the teacher analyzed the teaching content mainly by narration and students just listened passively so they lacked the initiative of learning.What’s more, because the teaching content is abstract, it’s extremely difficult for students to have a good under-standing.Based on modern theory of education, the teacher should know how to instruct students to simulate the mechanisms of regula-ting blood sugar, build and revise again and again dynamic physical model and then build abstract pictorial conceptual model of blood sugar regulation so that students can fully understand the regulation mechanisms of blood sugar and hormone regulation of life activities. That is not only an effective way to deal with the difficult teaching content but also a good significance to building students’ scientific ways of thinking.Combining the teaching practice in class, this essay introduces the teaching design about building the model of blood sugar regulation and the teaching strategies of building conceptual model.
