随着新课程改革的推行，学科育人方式和教学方式发生转变，教师需在教学过程中为学生创设真实的问题情境，帮助学生搭建思维阶梯，引导学生重现模型建构过程，落实学生核心素养的发展。本研究探查了学生基于初中化学项目学习教材中项目三“构建微观模型”学习后所达成的模型建构表现水平，形成了对学生模型建构表现评价的一般思路方法。本研究从建模能力与建模结果两个维度对学生模型建构表现进行评价，并结合文献、课例视频等资料构建具体的模型建构表现评价指标。随后结合学生在探究课、汇报课课堂中学生具体表现、项目作品等对其构建微观模型能力及构建微观模型结果进行评价、分析及总结，最后结合评价结果与具体教学环节建立关联讨论，提炼出能促进学生模型建构能力发展的关键教学策略。

With the implementation of the new curriculum reform, the way of educating people in disciplines and teaching methods has changed, and teachers need to create real problem situations for students in the teaching process, help students build a ladder of thinking, guide students to reproduce the model construction process, and implement the development of students' core literacy. This study explores the level of model construction performance achieved by students based on the learning of project 3 "Building a Micro Model" in the junior high school chemistry project learning textbook, and forms a general idea and method for evaluating the performance of student model construction. In this study, the students' model construction performance was evaluated from the two dimensions of modeling ability and modeling results, and specific model construction performance evaluation indicators were constructed based on literature, lesson example videos and other materials. Subsequently, combined with the specific performance of students in the inquiry class and debriefing class, the project works, etc. of the students were evaluated, analyzed and summarized for their ability to build micro models and the results of building micro models, and finally the evaluation results were combined with the specific teaching links to establish correlation discussions, and the key teaching strategies that could promote the development of students' model construction ability were extracted.
