基于“教学评”一体化的高中化学项目式教学——以“构建科学合理选药模型”为例

Project Based Teaching of High School Chemistry Based on the Integration of“Teaching,Learning,and Evaluation”——Taking“Building a Scientific and Reasonable Drug Selection Model”as an Example

以“合理选药”为项目研究主题,设计了4个主要活动,引导学生通过讨论交流提出若干子问题。依据子问题逐步完成学习任务。在运用所学元素及其化合物知识、设计实验探究问题的基础上,从化学视角构建合理选择药品模型。基于“教学评”一体化目标和过程性评价,设计了学生评价量表,在课堂上进行自评、互评、师评等评价活动。

With the theme of“rational drug use”as the project research topic,four main activities were designed to guide students to propose several sub questions through discussion and communication.Based on the sub questions,students gradually completed learning tasks.On the basis of applying knowledge of learned elements and their compounds,designing experiments to explore problems,a rational drug selection model was constructed from a chemical perspective.Based on the integrated goal of“teaching,learning,and evaluation”and process evaluation,a student evaluation scale was designed to conduct self-evaluation,peer evaluation,teacher evaluation,and other evaluation activities in the classroom.
