A simple way for students to visualize cellular respiration: adapting the board game MousetrapTM to model complexity

Lecture-based introductory biology courses are typically content-heavy as instructors strive to provide students with foundational knowledge in a broad range of topics.  One topic traditionally covered is cellular respiration, the series of enzymatic reactions that results in the formation of ATP, the energy currency in cells, from carbohydrates.  Cellular respiration is often difficult for students in these classes because the topic is both complex and ‘invisible’ – the students can’t observe the process.  In an attempt to overcome these difficulties and enhance student learning, we describe how the board game Mousetrap™ (Hasbro, Milton Bradley) can be adapted to model cellular respiration.  Mousetrap™ is ideal for this adaptation due to its 3-dimensionality, the necessary assembly of its 3D components and the interdependence of its 3D components. In the classroom, the pieces of the game are re-assigned into the three stages of cellular respiration (glycolysis, Krebs Cycle, electron transport chain); after each stage is discussed in lecture, students assemble that part of the board game.  By the end of class, the game is completely assembled, providing students with a workable model of the entire cellular respiration pathway.  Students then trigger the mousetrap to visualize the complete, dynamic process and ‘make ATP’ (i.e., catch the mouse).  Mousetrap™ serves as a dynamic, interactive, active learning tool that helps students build a basic, but accurate model for cellular respiration that can be used as a scaffold for subsequent upper-level courses or for more complex discussions related to fermentation, toxicology, and/or enzymatic regulation.

Exploring the Complexities of Photosynthesis Through a Comic Strip

Photosynthesis is a conceptually challenging topic. The small scale at which photosynthesis takes place makes it difficult for students to visualize what is occurring, and students are often overwhelmed by all of the details of the process. This activity uses a freely-available comic to make learning photosynthesis more approachable and to help students identify their own misconceptions and questions about the process. This activity is appropriate for any college-level introductory biology course and although it was designed for an online class, it could be adapted for in-person learning. In this activity, students work through a four-part online module. Each part consists of readings and videos containing background information on the steps of photosynthesis followed by the corresponding portion of a comic on photosynthesis. Students then use the background information in the module and the comic to identify their own misconceptions and questions and post these in an online discussion forum. The online module is followed by a live session in which the instructor uses the student discussion posts to clarify any remaining questions. Learning about photosynthesis in the unique visual format of a comic allows students to more easily visualize a process that they cannot see with their own eyes. Students enjoyed this activity because it makes learning photosynthesis fun and less intimidating. This lesson is powerful because it allows the instructor to hear from all students in the course via the discussion forum and then tailor the live discussion session to cover student identified problem topics.

Project Leadership Resources - Bringing Leadership Experiences into the Classroom

The Project Leadership Program is a pedgagogical approach that is designed to improve teamwork through the integration of shared leadership experiences. The program involves three components: a web-based App called Project Leadership, active engagement of student teams, and supportive coaching from instructors. This resource describes the program in more detail, shares user guides for the App, and provides examples of ways to integrate the program in different contexts.
