  1. Abstract Student-centered approaches are critical to improving outcomes in STEM courses. Collaborative learning, in particular, allows students to co-construct understanding of concepts and refine their skills in analyzing and applying information. For collaborative learning to be effective, groups must engage in productive dialogue. The work reported here characterizes the quality of dialogue during group quizzes in a first-semester organic chemistry course. The group quiz sessions were video and audio recorded. The recordings were transcribed and coded using the Interactive, Constructive, Active, Passive (ICAP) framework. The quiz prompts were analyzed using Marzano’s taxonomy. In this study, students within the group demonstrated varying degrees of interactional quality as defined by the ICAP framework. Our data also indicate that the level of constructive and interactive dialogue is highest and most consistent when prompts are at Marzano Level 3 or higher. Marzano Level 3 prompts required students to compare and contrast concepts or extend their understanding of concepts by developing an analogy. Any benefit derived from collaborative learning depends on the quality of dialogue during the group discussion. Implications of these results for research and teaching are offered.

  2. Students face various challenges in organic chemistry, including learning complex organic chemistry concepts, applying them to solve problems, and navigating curved arrow notation to depict organic chemistry mechanisms. Given these challenges, many chemistry education practitioners and researchers have focused their efforts on implementing and assessing pedagogical practices that can produce positive outcomes for all students. In this chapter, we describe flipped classroom pedagogy as an evidence-based practice in organic chemistry that has improved student outcomes and addressed learning challenges in the course. We also review key aspects of this practice. In addition, we focus on group activities since they are a common component of flipped classrooms. We will present a case study that analyzes students' reasoning through dialogue when they were engaged in a group quiz activity that was a component of a flipped organic chemistry course. Through the results of this case study, we will make suggestions for how group activities can be implemented to improve students' reasoning skills in organic chemistry.
