学生在日常活动中,接触自然界中的各种事物,观察到各种物理现象,获得了不少的物理知识和一些有关的生活经验.这些知识、现象和经验虽然是粗浅和感性的,但多数是符合客观规律的,因而对学习物理是有利的。然而,生活经验一般没有经过科学论证,有些是不符合物理规律的,非但无助于学习物理,甚至在形成思维定势后,往往会顽固地妨碍学生对物理规律的正 In daily activities, students are exposed to various things in the natural world, observed various physical phenomena, acquired a lot of physical knowledge and some related life experiences. Although these knowledge, phenomena and experiences are superficial and emotional, the majority It is in line with objective laws and is therefore beneficial to learning physics. However, life experience is generally not scientifically proven, and some are not in accordance with the laws of physics. Not only does it not help to learn physics, and even after thinking habits are established, they tend to obstruct students’ physics laws stubbornly.
