Here, we describe the implementation a hybrid general chemistry teaching laboratory curriculum that replaces a portion of a course’s traditional “wet lab” experiences with online virtual lab modules. These modules intentionally utilize representations on all three levels of the chemistry triplet—macroscopic, submicroscopic, and symbolic. The implementation of this curriculum allowed an opportunity to evaluate this new course structure. First, student performance was assessed based on pre- and post-assessments. Second, dialogue from students working through the traditional and module versions of one lab was analyzed for how each format encouraged students to engage with the chemistry triplet. Data suggest both formats led to positive learning gains, but the differences between formats were not statistically significant. However, there was a significant difference in student engagement with the chemistry triplet, with module students showing a higher overall amount of triplet-related dialogue and more continuous dialogue segments connecting multiple levels of the triplet.

在普通化学课程中实施湿实验室和在线模块实验室混合课程的效果：对化学三重奏对学生成绩和参与度的影响

在这里，我们描述了混合型普通化学教学实验室课程的实现方式，该课程用在线虚拟实验室模块代替了课程传统的“湿实验室”体验的一部分。这些模块有意使用化学三重态的所有三个级别上的表示形式-宏观，亚微观和象征性。该课程的实施为评估该新课程结构提供了机会。首先，根据评估前后对学生的表现进行评估。其次，分析了通过一个实验室的传统版和模块版进行工作的学生之间的对话，以探讨每种形式如何鼓励学生参与化学三元组。数据表明，两种格式都可以带来积极的学习成果，但是两种格式之间的差异在统计上并不显着。然而，
