新课标从“知识与技能”、“过程与方法”、“情感态度和价值观”三方面提出了课程目标,但在教学实践中,可以通过习题解答来考察三维目标的落实。而力学又是一项要求对常见自然规律和现象所包含的科学知识进一步理解和掌握的内容。在教学实践中我们不难发现,学生由于阅历尚浅、概念规律掌握片面、错误前概念、计算能力薄弱等因素影响,难免会在解答练习题时出现诸多问题。下面笔者就学生在解答力学习题时出现的典型错误进行分析,并提出相应的矫正措施。
The new curriculum standards from the “knowledge and skills ”, “process and method ”, “emotional attitude and values ” three aspects of the curriculum objectives, but in teaching practice, you can study the solution to examine the three-dimensional goals implement. Mechanics, on the other hand, is a requirement for further understanding and mastery of the scientific knowledge contained in common natural laws and phenomena. In teaching practice, we can easily find out that due to the inexperience of students, the unilateralism of concepts and laws, the preconceived notion of mistakes, the weak ability of calculation and so on, students will inevitably encounter many problems in answering the exercises. The following author on the mechanical problem solving students to analyze the typical mistakes and put forward the corresponding corrective measures.
