小學的物理教學雖然大部分是以定性的闡明物理現象為主,伹是有許多內容还是要涉及定量方面的。所以在教學中必然要用到一些公式,把现象之間的關係從定量上聯系起來,並進而從已知條件中來推算所求的物理量,以解决實際問題。一般說來,數學基礎較差的学員對計算問題是感到一定困難的。常常會聽到他們說:“一些道理還好說,碰到計算題就伤腦筋了。”雖然在中學物理中計算問題並不太多,但如果這些問題講不好,學員在實際演算過程中便會感到困難,而對学習物理可能產生一種畏懼心理,認為物理真不好學,結果把他們學習的兴趣也降低了,教學任務當然也就無法完成。所以應 Although most of the physics teaching in primary schools is based on qualitative clarification of the physical phenomena, there are many contents or quantitative aspects to be involved. Therefore, some formulas must be used in teaching to quantitatively link the relations between phenomena and then calculate the physical quantities sought from the known conditions so as to solve practical problems. Generally, students with poor maths experience some difficulty in calculating the problem. They are often told to say, “Some truths are good to say that it can be a daunting task to solve a calculation problem.” Although there are not many calculation problems in high school physics, if these problems are not well understood, Will find it difficult to study physics but may have a fear of psychology and think that physics is not good at learning. As a result, their interest in learning is also reduced, and of course teaching tasks can not be completed. So should
