我们认为:当说明原子内电子的状态时,必须让学生知道电子两重性的初步知识。关于电子作为微粒和云状的概念,将在九、十年级的课程学习中逐步获得。因此在八年级的课程中广泛使用直观手段,以避免抽象地解释原子内电子状态这一理论问题是有裨益的。我们得出的结论是,模型或图表可以加深学生对所学课题或现象的某一方面的学习、理解。为让学生对他们所学的事实形成更加完整的概念,必须使用一系列各种不同的模型、图表以及放映电影。
We believe that when explaining the state of electrons within an atom, students must be made aware of the preliminary knowledge of electron duality. The concept of electrons as particles and clouds will be gradually acquired during the course of the 9th and 10th grades. Therefore, the use of intuitive means in the course of the eighth grade is beneficial to avoid the theoretical problem of abstractly interpreting the electronic state within the atom. We have come to the conclusion that the model or diagram can deepen students’ learning and understanding of a certain aspect of the subject or phenomenon they are studying. In order for students to form a more complete picture of the facts they have learned, it is necessary to use a series of different models, charts and film screenings.
