“科学探究:凸透镜成像”一节是光学的重点也是难点。对于初学物理的初二学生来说,要独立完成本节的科学探究是相当难的。结合学科特点和学生特点以及本节的教学目标,在教学中可采用教师先引导学生根据凸透镜在生活中的不同成像情况进行合理猜测,再依次进行科学探究的教学方式。尤其在设计实验时,教师用矛盾展现的方式,让学生去思考、讨论,师生共同设计合理的探究过程。整个教学的适当调整和合理设计,充分调动了学生的思维,让学生真正参与到课堂中来,学会学习。
The “Science Exploration: Convex Imaging” section is the focus and difficulty of optics. For second-year students in beginner physics, it is quite difficult to independently complete the scientific inquiry in this section. Based on the characteristics of the discipline and the characteristics of the students and the teaching objectives in this section, teachers can be used to guide students to make reasonable guesses based on the different imaging conditions of the convex lens in life, and then conduct scientific inquiry teaching methods. Especially when designing experiments, teachers use contradictory methods to allow students to think and discuss. Teachers and students jointly design a reasonable inquiry process. The proper adjustment and rational design of the entire teaching fully mobilized the students’ thinking, allowing the students to truly participate in the classroom and learn to learn.
