论文部分内容阅读
电学部分是初中物理的重点,抽象的电学知识对初中生来说更是个难点。其中串并联电路的电流、电压、电阻的关系是学好电学的基础,学生能否深刻地理解它们之间的关系,将直接影响到学生对这部分内容能否熟练掌握和应用。利用比喻来说明一些错综复杂、抽象难懂的道理,将深奥晦涩的电学形象化、具体化,既能活跃课堂气氛,加强学生的主动参与意识,又能拓宽学生的知识面,融洽师生关系。更重要的是学生对知识的理解和掌握轻松多了。这样会极大地提高学生的学习兴趣,提高教师的个人魅力,使学生由喜欢这个老师发展到喜欢物理这门学科。
Electrical part is the focus of junior high school physics, abstract electrical knowledge is more difficult for junior high school students. Among them, the relationship between current, voltage and resistance of series-parallel circuit is the basis of learning electrical. Whether students can understand their relationship profoundly will directly affect the students’ mastery and application of this part. The use of metaphor to illustrate some intricate, abstract and difficult to understand the truth, the esoteric obscure electrical visualization, specific, both active classroom atmosphere, to enhance students ’awareness of active participation, but also broaden students’ knowledge, harmonious relationship between teachers and students. More importantly, students’ understanding and mastery of knowledge is much easier. This will greatly enhance students’ interest in learning and improve their personal charisma, so that students from the development of this teacher to like the physics of this discipline.
