利用学生的前概念建构科学概念的一些策略研究

Strategies of Building Scientific Concepts by Way of Students' Preconceptions

小学科学教育的价值,是使孩子们在接受正式科学教育之初就能够发展起对自然以及对自己周围世界的理解,建立起自己的观点和想法。如果在探索世界的过程中没有被科学地引导,那么他们形成的观念就有可能是非科学的,并且可能妨碍到以后的学习。学生在学习科学概念之前,对这些概念大都有了一定的认识和了解,这种已有的认识和了解即为科学学习中的前概念。阐述了前概念在学生的科学学习中的重要作用。

The value about science education in primary schools lies in the enlightment on students in developing their own understanding about the nature and their surrounding environment and forming their own opinions and thoughts before re- ceiving the formal scientific education. Without a scientific guidance during their exploration of the world, their concepts may be non-scientific or even hinder them from receiving following learnings. Before the learning of a new scientific concept, students have already had their own understanding on the concept. This is called preconception in scientific learn- ing. This paper describes the importance of preconception for students in their learning of scientific knowledge.
