一、引导学生主动探索,培养探究意识在教学过程中,教师可以适当帮助学生设疑,让学生进行实验或展开讨论,指导学生通过积极思维,亲自体会探究问题的过程,而得以自悟。在《物质跨膜运输实例》一课中关于“水分的运输”的学习时,教师提出问题:水分怎样进入根毛区的表皮细胞?然后又是怎样被运输到根导管中的呢?并假设:水分是先通过根毛区的表皮细胞,再通过内层细胞逐层进入导管内的。接着就可提供实验条件让学生
First, to guide students to take the initiative to explore and develop a sense of inquiry In the teaching process, teachers can help students set up suspicions, let students experiment or discussion, to guide students through positive thinking, personal experience to explore the process of the problem, and be able to self-awareness. In the lesson about “Transport of Moisture” in the Lessons Learned from Trans-Membrane Transportation example, the teacher asks: How does moisture enter the epidermal cells of the root hair area and then how it is transported into the root canal? And Hypotheses: Water is first passed through the epidermal cells in the root hair area and then into the catheter layer by layer through the inner cells. Then you can provide experimental conditions for students
