This resource aims to educate students about the concept of opportunity cost in relation to educational decisions, specifically focusing on calculating the total economic cost associated with a two-year postsecondary education path. Through a scenario involving a character named Sam, students will engage in activities that require them to define economic concepts such as explicit and implicit costs, apply these concepts to calculate the total economic cost of attending a trade school compared to working in a construction job, and reflect on factors influencing their educational choices. The resource includes a structured progression from retrieval practice to guided application, culminating in a metacognitive assessment on the students' confidence in their calculations. Additional challenges encourage deeper analysis of opportunity costs, such as considering future wage increases.
