STEM Lessons - Model Eliciting Activity
In this Model-Eliciting Activity (MEA), the general manager (GM) of a National Football League (NFL) team has to decide which injured players to going to cut (remove) from the team and which players to keep. This is a very difficult decision for the GM to make. The GM cares about the players and this decision will end the football careers of those who are cut. This happens every season, so the GM wants a system that can be used to make this decision every year. Experts in the organs of the human body and their functions are needed to create this system.
Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. MEAs resemble engineering problems and encourage students to create solutions in the form of mathematical and scientific models. Students work in teams to apply their knowledge of science and mathematics to solve an open-ended problem while considering constraints and tradeoffs. Students integrate their ELA skills into MEAs as they are asked to clearly document their thought processes. MEAs follow a problem-based, student-centered approach to learning, where students are encouraged to grapple with the problem while the teacher acts as a facilitator.

This Model Eliciting Activity (MEA) is written at a 5th grade level. In this open-ended problem, students are presented with a variety of exercise machines, the best health feature of each machine, prices, and popularity (based on a local competitor's gym). Students must rank the exercise machines and describe their procedures for ranking. The durability of each machine feature is later added as a twist so that students can revise or test their original procedures.
