Abstract: This study used a curriculum inquiry framework to investigate the perceptions of 184 nursing students and nurse educators in relation to bioscience in the nursing curriculum. Nursing students were found to have significantly more positive attitudes to bioscience in nursing education than nurse educators, and nurse educators were not found to have significantly better self-efficacy in bioscience than the students, although this might have been expected. The results of focus group discussions, used to investigate this in more depth, suggested that some nurse educators and clinical preceptors may not have sufficient science background or bioscience knowledge, to help nursing students apply bioscience knowledge to practice. As a result of this, it is suggested that the aims of the intended and prescribed nursing curricula are not being fulfilled in the implemented curriculum.
