1.善观察。物理是一门以实验为基础的学科,通过观察不仅可以获得丰富的感性材料,还形成对事物的初步认识,是进行理性思维的前提和基础,比如各种实验仪器实物的观察,课本中小资料数据的观察,在观察实验,图表的同时,更要注重对实验现象的观察。在做八年上册第三章第4节给碘加热的实验,实验中碘的状态变化,然后总结出升华、凝华的特点等。2.勤联系。在学习中应把书上理论和实验看到的现象联系起来,并与生产、生活中相关的物理现象联系起来,加深理论的
Good observation. Physics is an experiment-based discipline. By observing it, not only rich and perceptual materials can be obtained, but also a preliminary understanding of things is formed. It is the precondition and foundation of rational thinking. For example, the observation of various experimental instruments in kind, Observation of data, observe the experiment, the chart at the same time, but also pay more attention to the observation of the experimental phenomenon. In eight years on the book Chapter III, Section 4 to iodine heating experiment, the experiment state of iodine changes, and then sum up the characteristics of sublimation, sublimation and so on. 2. Qin contact. In learning, the theory of the book should be linked with the phenomena seen in the experiment, and be linked with the physical phenomena related to production and life, to deepen the theoretical
