一、活化知识的教学从课堂教学看,知识教学太死是产生厌学的一个重要原因。我在长期的教学实践中,为唤起学生对物理学科的热爱,积极探索如何把知识教活。活,就是让学生感受知识的力度,用生活中的实例说明知识的价值。教学中突出以下几点:①讲清知识的由来,增加信度;②加强知识与学生生活的联系,坚持理论与实践相结合的原则,使学生逐步认识到物理就在我身边,增强真实感;③完成知识、能力的转化,学用结合。这样使学生信物理,进而把学习看成人类生存的必需,使掌握知识、发展能力变为一种吸引人和学生愿意做的事情。把教学搞活,首先要使学生对知识有切身感受。用实验、生活实例、工农业生产的技术作用于学生各种感觉器官,领会文字符号所描述的物理现象或过程。例如,教全电路欧姆定律时,先拆看手电筒,后绘电路图,再研究各元件的作用。导出I=ε/(R+r)后,类比成抽水
First, the activation of knowledge teaching From the classroom teaching, knowledge teaching is too dead to produce weariness is an important reason. In my long-term teaching practice, I arouse students' love of physics and actively explore how to teach knowledge. Live, is to let students feel the strength of knowledge, use examples of life to illustrate the value of knowledge. Promote the following points in teaching: ① clarify the origin of knowledge, increase the reliability; ② strengthen the link between knowledge and student life, adhere to the principle of combining theory with practice, so that students gradually realize that physics is on my side and enhance the sense of reality ; ③ complete the transformation of knowledge, ability, learning with combination. This makes students believe in physics, and thus learning as a necessity for the survival of human beings, so that knowledge, ability to develop into a kind of attractive and students are willing to do. Invigorating teaching, we must first make students have personal experience of knowledge. Using experiments, examples of life, techniques of industrial and agricultural production on the various sensory organs of students, and comprehending the physical phenomena or processes described by the symbols. For example, to teach the whole circuit Ohm's law, first disassemble the flashlight, painted circuit diagram, and then study the role of the components. After deriving I = ε / (R + r), the analogy is pumping
