10、考的考点所在。同学们要学好物理并在中考中取得理想的成绩，在初三阶段的学习过程中应注意做好以下几点：(1)立足课堂，夯实根底。课堂是学习物理根底知识和根本技能的主阵地，只有把握课堂，抓牢双基，学习必要的方法，才会有拓展、提高的可能。(2)注重探究过程，学习研究方法。物理是一门实验科学，学习物理要注重科学探究的过程，对于每一个实验探究不仅要知道怎样做，而且要理解为什么要这样做，并能对探究过程和结果作出适当的评估;除了学习物理知识，还应学习相关的研究方法，如：转化法，控制变量法，比照法，理想实验推理法，归纳法、等效法、类比法、建立理想模型法等。(3)强化训练，提高知识的迁移应用能力。课外适当做一些补
11、充练习是消化、稳固所学知识，拓展提高的一种较为有效的措施。在解题过程中注意培养、提高审题能力。(4)优化学习方法，提高学习效率。如遇到学习的难点、疑点，由于初三阶段的学习较为紧张，不能花很多的时间去慢慢磨，应做好标记，跟同学讨论，最好求得老师的解答，理解过程，掌握方法。(5)归纳概括、串前联后，形成综合能力。在平时的学习过程中，对所学的知识进行必要的归纳总结，并将新学的知识和前面的内容联系起来，注意它们的相同点与不同点，做到|精.|品.|可.|编.|辑.|学.|习.|资.|料.*|*|*|*|欢.|迎.|下.|载.第 3 页，共 4 页文档编码:CV9P3T2A3J1 HC10X8W3U4Z5
