理論与实际相結合是中学物理教学的根本原則。但在教学实踐中,对理論与实际的关系却往往处理不当,发生問題。或則脫寓实际,片面追求理論;或則輕視理論,狹隘理解实际。其結果都不能达到理論和实际相結合的要求,因而必然要影响到教学的貭量。当前的中学物理教学中,理論固然不容忽視,但更重要的仍然是进一步加强理論与实际的結合,彻底克服脫离实际的偏向。这里只就几 The combination of theory and practice is the fundamental principle of high school physics teaching. However, in the teaching practice, the relationship between theory and practice is often mishandled and problems occur. Or the real practice, one-sided pursuit of theory; or contempt theory, narrow understanding of reality. The result can not meet the requirement of combining theory and practice, so it is bound to affect the teaching quantity. In the current middle school physics teaching, the theory can not be ignored, but more important still is to further strengthen the combination of theory and practice and thoroughly overcome the deviation from reality.
