STEM can be incorporated into a marketing course through project-based learning such as a food truck business project that integrates marketing, investing, management, and entrepreneurship. Students apply math to budgeting, pricing, and comparing off-brand versus name-brand food costs, while technology is used for social media marketing, digital design, and data analysis. Problem-solving and analytical thinking are used in event planning, inventory decisions, and evaluating customer preferences. By combining STEM with marketing concepts, students develop real-world skills in critical thinking, financial literacy, and strategic decision making.
