Experiencing FPBL (Free Project Based Learning) can develop effective content delivery for both teachers and students. With FPBL where students are free to choose their own projects they become intrinsically more motivated and self-confident. In this research study two groups (control group and experiment group) of students are used and two exams are developed to evaluate the students' achievements. A remarkable difference in favor of experiment group was found. The results provide a starting point for educators and researchers seeking to assess new approaches to project-based learning.
