The multiple case study investigated levels and types of transfer observed in a K-8 STEM (science, technology, engineering, math) academy in a project-based learning (PBL) environment. The academy was constructed two years prior to the study and conducive to PBL instruction. The students and teachers were in the second year of using PBL in the subject of science at the time of the study. The grade levels observed were second, fourth, and sixth grade and each grade level had three PBL units examined from the beginning to the end of the unit. The nine case studies, from the three different grade levels, were observed to identify Haskell's levels and types of transfer as determined by project requirements, observation of students, completed projects, and student interviews. The findings from this study showed that while projects moved the students beyond knowledge acquisition to application of knowledge in completed projects such as books, films, dances, etc., higher levels of transfer and more types of transfer were not evident. Therefore, based on the results of this study, the evidence of lower levels of transfer suggests that the PBL units, though inventive and potentially valuable to student learning, were not designed for higher levels of transfer.
