一、教学中存在的问题初中物理电路计算题,由于其公式的灵活多样以及所涉及电学知识点之间的广泛联系,始终是中学生感到头痛的问题,尤其是较为复杂的综合性电学计算,往往是中考中作为考察学生逻辑思维能力的难题,如:2006年上海市中考第17题(电路中涉及到两个电表指针偏离零刻度的角度恰好相同)、2009年上海市中考第22题(电路中三个电表的示数同 First, the problems in teaching Middle school physics circuit calculation problems, due to its flexible formula and the extensive contact between the electrical knowledge involved, has always been a problem for secondary school students, especially the more complex integrated electrical calculation, often Is the exam in the exam as a logical problem of thinking ability of students, such as: Shanghai High School Entrance Examination in 2006 No. 17 (the circuit involves the two meter pointer deviation from zero point of view exactly the same angle), 2009 Shanghai exam 22 (Circuit In the three meters show the same number
