AR技术对高中生化学有机物微观结构学习的影响

Effects of Augmented Reality on the Chemistry Learning of Organic Matter′s Microstructure in High School Students

AR技术已用于支持学生学习化学微观结构知识。通过准实验设计,以高一年级化学课程有机物“烃”分子结构知识为例,探究AR技术对学生在微观结构知识学习效果、空间旋转可视化能力、AR技术使用态度的影响。研究发现,AR技术对学生微观结构知识学习产生显著的教学即时效果和良好的教学保持效果,对学生空间旋转可视化能力发展的影响不显著,使学生产生正面的AR技术使用态度。建议加强AR技术融入化学微观结构知识学习的教学应用研究、学习资源开发研究和教学成效实证研究。

Augmented reality(AR)has been used to support students′learning of the microstructure in chemistry.Using a quasi-experimental design and taking the knowledge of the molecular structure of organic matter′hydrocarbon′in high school chemistry course of grade 10th as an example,the effects of AR on students′learning regarding the knowledge of microstructure,the ability of visualization of rotations,and the attitude towards AR usage were explored.The results showed that AR had a significant immediate teaching effect and a good retention teaching effect on students′learning regarding the knowledge of microstructure,and had no significant effect on the development of students′ability of visualization of rotations;students had a positive attitude towards the use of AR.It is suggested to strengthen the research on the application of AR integrated with the teaching of the knowledge concerning the microstructure in chemistry,the development of learning resources,and the empirical research on teaching effect.
