三为主四环节教学是指教师在教学过程中帮助学生自己进行知识构建,引导学生自己去认识和发现问题,激励学生积极动手、动脑,通过自主的探究学习获得知识的一种教学模式。我对实验课的“三为主四环节”模式进行了初步研究。1发现问题;2科学假设;3设计实验搜集证据;4分析数据、得出规律。一、教学设计1.培养学生用控制变量法寻求规律的能力让学生做、观察、逻辑推理、抽象出规律本质,真正使学生成为“学习的主人”。启发学生的思维,提高学生主动积极参与探究的
The three main four links teaching is that teachers in the teaching process to help students build their own knowledge and guide students to recognize and identify problems on their own to motivate students to actively use their brains and learning through independent learning to acquire knowledge of a teaching model. I conducted a preliminary study on the “Three Main Four Links” mode of the experimental class. 1 found the problem; 2 scientific hypothesis; 3 design experiment to collect evidence; 4 analyze the data and draw the law. First, the teaching design 1. Students are trained to use the method of control variables to find the law of the ability to make students do, observation, logical reasoning, abstraction of the nature of law and truly make students become “master of learning ”. Inspire students ’thinking and improve students’ active participation in inquiry
