笔者最近研读了许多物理类教学杂志的大量高质量文章,受益匪浅,深感对自己的教学和教科研能力的提升有很大的促进作用。但是在研读的过程中发现《物理教学探讨》2013年第11期中《用能量守恒思想拓展“完弹模型”》、《物理教学》2013年第12期中《拓展动能定理,解决三类内力做功问题》、《物理教师》2014年第1期中《一种形象直观理解“能量守恒定律”的方法》、《中学物理教学参考》2014年第5期中《我们的学生到底缺少什么——一次物理“基础学力”的调查与启示》等许多文章在研究子弹打木块问题时使用同一幅插图(或类 The author has recently studied a large number of high-quality articles in many physics teaching journals, benefiting a great deal and deeply influencing my teaching and teaching research capabilities. However, during the course of research, I discovered the “Theory of Energy Conservation”, “Extension of the Energy Conservation Theory” and “Physical Education” in the 12th issue of 2013, “Extending the Kinetic Energy Theorem to Solve Three Types of Internal Forces” “How to Do Work”, “Physics Teachers” in the first issue of 2014, “Methods of Intuitive Understanding of Images,” “Methods of Conservation of Energy,” and “References to Physics Teaching in Middle Schools,” No. 5, 2014, “What our students really lack - A number of articles such as ”Investigation and Enlightenment of Physics,“ ”Academic Forces," used the same illustration (or class) when studying bullets to hit a wooden block.
