摘要
针对饱和溶液教学存在的不足,从“定性、定量”的角度出发,以POE教学策略为支撑,融合PhET平台提供的虚拟仿真实验促进学生对饱和溶液相关概念的理解。通过自行预测可行方案、观察可视化宏观表象、解释浓度传感器所记录的数据变化、强化概念迁移解决实际问题,帮助学生从定性和定量相结合的视角认知饱和溶液的本质。
To address the shortcomings of teaching saturated solutions traditionally,this study designed an innovative teaching design for saturated solutions by integrating the PhET virtual simulation experiments and POE teaching strategy based on qualitative and quantitative perspectives.In the teaching sequences,students will get through predicting feasible solutions,observing visual macroscopic representations,interpreting data changes to learn related concepts of saturated solutions.The proposed teaching design may provide an insight into how to teach chemistry by PhET and contribute to students learning saturate solution.
