采用教师启发、引导,学生讨论、交流的教学方法,利用多媒体动画,引导学生自主思考讨论;通过对α粒子散射实验的结果分析从而否定葡萄干面包模型,得出原子的核式结构模型;既培养了学生推理、归纳总结的能力,又让学生了解了科学的研究方法。 Using teaching methods inspired by teachers, guiding students to discuss and exchange, using multimedia animation, to guide students to think about their own issues; by analyzing the results of α particle scattering experiment to negate the raisin bread model, derived nuclear atomic structure model; Students reasoning, summarized the ability to summarize, but also allow students to understand the scientific research methods.
