Numerous studies illustrate the value of simulations or project-based learning approaches to enhance the learning of science. Simulations can help students connect across macroscopic, microscopic, and symbolic representations of scientific phenomena, while project-based learning can provide a meaningful narrative and activities for students to…

There is an assumption that graduate teaching assistants (GTAs) have mastery of the chemistry content they are teaching and preparation to instruct students. However, in reformed classrooms, GTAs may need more support and resources. We designed chemistry rehearsal modules for use in a mixed-reality teaching simulator to help prepare GTAs for…

A student-choice model course redesign was used to counteract a large increase in student enrollment, improve the quality of instruction, and preserve student success. This model is an instructional technique that allows students to choose how to engage in a course. Using this model in a first-semester college-level general chemistry course,…

Many studies have used the potential of computer games to promote students' attitudes toward learning and increase their learning performance. A few studies have transformed scientific content into computer games or developed games with scientific content. In this paper, we employed students' common misconceptions of chemistry regarding the…

Ensuring that all students, including English language learners (ELLs) who speak English as a second language, succeed in science is more challenging with a shift towards learning through language-intensive science practices suggested by the Next Generation Science Standards (NGSS). Interactive visualization technologies have the potential to…

As the use of project-based learning becomes more frequent in the K-12 science classroom, and in chemistry classrooms in particular, teachers have begun to identify practical questions about implementation that should be addressed empirically. One such question concerns whether there is an ideal group size that fosters individual student…

Chemistry instructors in teaching laboratories provide expert modeling of techniques and cognitive processes and provide assistance to enrolled students that may be described as scaffolding interaction. Such student support is particularly essential in laboratories taught with an inquiry-based curriculum. In a teaching laboratory with a high…

Animations of molecular structure and dynamics are often used to help students understand the abstract ideas of chemistry. This qualitative study investigated how the features of two different styles of molecular-level animation affected students' explanations of how sodium chloride dissolves in water. In small group sessions 18 college-level…
