美国学生物理概念研究的发展

The Development of Research on Physics Concept of American Students

美国的物理教育研究者采用了访谈、量表和计算机辅助测试技术对力学和电学等领域的学生物理概念进行研究，得出以下结论：（1）前概念广泛存在于学生头脑中，并会严重影响物理概念的学习；（2）传统教学很难改变学生的前概念；（3）有效“转变学生概念”的教学策略是激发学生认知冲突。

The physics educational researchers of the USA have adopted interview, inventory and computeraided testing technology to study students＇ physical concepts about mechanics, electricity for a long time. They concluded that preconception exists in students＇ brain broadly, and preconception affects learning of physical concepts badly; traditional teaching can hardly change students＇ preconception; the effective teaching strategy of ＂conceptual change＂ is to inspire students＇ cognitive conflict.
