The purpose of this study was to use a case study design to examine the impact of a blended learning instructional model on students in an Advanced Placement (AP) Macroeconomics course. Using an instrumental case study design, the researcher investigated blended learning and students’ perceptions of their own interactions with the materials as well as perceptions of overall performance in the course. The study also used grade point averages (GPA), LMS Usage Reports, and AP exam scores to triangulate with the interview data. The key factors influencing the students’ views were discussed, an enhanced model of blended learning was proposed, recommendations for future research were made, and strategies and practices were offered
