Logic Design is one of the core courses of many engineering programs and it provides a foundation for the subsequent hardware courses in the curriculum. In this study, a course design supported by open courseware for Logic Design is presented. In this regard, the syllabus, slides, laboratory manual handbook including experiment sheets and simulations, experiment videos, assignments and examples were prepared. The aim of this research is to determine the effect of supporting Logic Design course with digital open courseware on student achievement. It also aims to determine students' opinions regarding this approach. The study follows a mixed methods approach with the pretest-posttest control group experimental research design. The study was conducted at Manisa Celal Bayar University in Turkey in spring semester of the academic year 2017-2018 with 68 computer engineering students. While the students of the experimental group took the course supported with open courseware, only regular instruction was used in the control group. The quantitative data were collected from an achievement test including open-ended questions and surveys. The qualitative data were gathered by semi-structured focus group interviews. The findings were meticulously analyzed to provide suggestions for revision of the course. Finally, future work directions are discussed.
