Diversity and inclusivity in higher education and health care have gained prominence in recent years and this means that institutions’ educational programmes need to incorporate teaching and learning that is responsive to diversity. This paper reports findings from a diversity teaching and learning mapping project. The aim of the mapping project was to map out when and how the various themes on diversity in all course curricula are addressed in a university’s School of Nursing. The project adopted the following methodologies: documentary reviews of curriculum documents, handbooks and timetables, followed by qualitative interviews with module leaders and teachers. The documentary reviews provided a map of where diversity teaching and learning tended to occur and the interviews yielded six major themes central to diversity: definition, importance, confidence, challenges, resources and future implications. The results suggest that mapping does provide an important way of comparing courses and highlighting aspects which need attention. The results provide directions for curriculum development teams to ensure that diversity issues are transparently addressed in all courses in the School of Nursing. Furthermore, the insights derived from the findings steered the project team to develop Web CT resources on some of the diversity themes such as an introduction to diversity and inclusivity, spirituality, ethnicity and diversity. Plans are in place to develop further diversity teaching and learning resources in the light of findings which will be used in staff development programmes. 相似文献

This paper describes an evidence‐based quality assurance system for teaching and learning, which takes as its starting point a well‐researched theoretical perspective on student learning in higher education. We argue this explicit use of a relevant theoretical base promotes coherence between quality assurance and improvement processes. We outline the principal features of our university's quality assurance strategy, systems and processes, and describe how the university's teaching quality assurance policy and systems have been implemented. We then consider the extent to which the project has achieved its goals of fostering an evidence‐based approach to teaching consistent with the student learning perspective on which the policy and systems are based. We also present data on student learning experiences showing reliable changes in the quality of the student learning experience. We discuss the applied significance of these changes, with a particular focus on changes in the experiences of commencing first year university students. 相似文献

While the use of Web 2.0 tools and specifically blogs is becoming increasingly popular within higher education (HE) and has been shown to promote learning, relatively little is known about the manner in which such tools may affect how teaching and learning may change as a result of the use of such tools. It is within this context that a connectivist learning model was created and has been further developed within this paper in order to consider the implications of how the use of blogs may change the manner in which teaching and learning occurs. Within this research, a case study of the use of collective student blogs utilized as part of a formally assessed module, undertaken within an HE institution, is utilized to explore the manner in which teaching and learning can be seen to change through a connectivist learning model of blog usage. From this case study, it appears that connectivism does provide a theoretical model for the way in which teaching and learning may change as a result of the use of blogs by learners. However, the experience of staff and students who undertook the project suggests that while a number of elements of the connectivist model can be identified, these are not seen universally among all students. 相似文献
