(一) “科学猜想”是研究自然科学的一种广泛应用的思想方法,它不同于无根据的幻想,而有它的客观根据,它是科学性和假定性的辩证统一。这就是说,它是根据已知的科学原理和科学事实,对未知的自然现象及其规律性所作出的一种假定性的说明或假定性命题。应该指出,这样的假定性命题是否正确,尚需通过实验来验证和理论上的论证。物理教学中在揭示现象的因果关系和本质联系或探索物理规律的过程中,有计划地适当运用“科学猜想”的方法有很大的积极意义。在教学实践中我们体会到它有如下几点好处:(1)可以激发和保持学生对所研究问题的兴趣和注意力,促进他们的定向思维活动,从而产生进一
(1) “Scientific conjecture” is a widely used method of thinking in the study of natural sciences. It differs from unfounded illusions but has its objective basis. It is a dialectical unity of scientificity and presumption. This means that it is a hypothetical explanation or hypothetical proposition of unknown natural phenomena and their regularity based on known scientific principles and scientific facts. It should be pointed out that whether such a hypothetical proposition is correct still requires experimental verification and theoretical argument. In the process of revealing the causality and essential connection of phenomena or exploring the laws of physics in physics teaching, the method of using scientific guesswork in a planned way has great positive significance. In the teaching practice, we realize that it has the following advantages: (1) It can stimulate and maintain students’ interest and attention on the research issues, and promote their directional thinking activities, resulting in a further
