以“丁达尔效应”为例探讨科学探究的教与学

Discussion on Teaching and Learning of Scientific Inquiry with“Dingdal Effect”as an Example

在新课程标准背景下,科学探究与创新意识这一核心素养要求从实践层面激发学生学习兴趣,培养科学思维。本文以"丁达尔效应"实验为例,通过引入科学探究,深入问题的内核,探讨了布朗运动、光的散射与丁达尔效应的关系。充分利用科学探究实验,在提高学生对相关知识了解和加深理解的同时,可增强学生的趣味点和参与度,提高教学质量。通过优化课程设计,加深学生对化学知识的掌握。

The core quality of scientific inquiry and innovation consciousness requires stimulating students interest in learning and cultivating scientific thinking from the practical levelunder the background of the new curriculum standard.Taking the experiment of“Dingdal effect”as an example,through the introduction of scientific inquiry,the relationship between Brownian motion,light scattering and Dingdal effect was discussed.Making full use of scientific inquiry experiment can not only improve students understanding of relevant knowledge,but also enhance students interest and participation,and improve the quality of teaching.Through the optimization of curriculum design,students mastery of chemical knowledge can be deepened.
