The National Teaching Repository − Sharing effective interventions: Learning from each other so that we can continue to enhance and improve what we do

The National Teaching Repository (NTR) is a widely recognised Open Educational Resource (OER) that has made a significant impact on the global higher education community. Recently, the UNESCO Secretariat invited the NTR team to present reports on the repository’s reach and impact (Wooff and Irving-Bell, 2022), which has prompted this article. In it, we provide an overview of the NTR’s origins, values, and vision, and we also extend an invitation for you to join us in this exciting initiative

Risks, reflection, rewards, and resistance: academic perspectives on creative pedagogies for active learning

In recent decades there has been a paradigmatic shift in higher education towards active learning, requiring educators to adopt student-centred approaches to teaching to promote deep learning and the development of essential graduate attributes. A ‘Creative pedagogies for active learning’ course was designed to offer academic staff an opportunity to take risks in developing innovative student-centred teaching approaches. While participants encountered ‘dissonance’ during the early stages of the creative pedagogies course, the course leads were able to support participants through this period of uncertainty and risk-taking towards successfully disrupting their own teaching practice. This reflective analysis paper outlines the course and showcases several case studies of practice by participants. We also reflect on their experiences through a subsequent roundtable discussion. This revealed that the course had made a longer-term impact on some participants in terms of their teaching and assessment practice and showcasing this to other educators. However, resistance to change in some departments was noted, making it difficult for staff to implement creative pedagogies more widely in practice. Suggestions for overcoming resistance are presented, and the paper concludes with future directions for taking this work forward

On the nature of the 'heterogeneous' catalyst: Nickel-on- charcoal

Results from aromatic aminations and Kumada couplings, together with spectroscopic analyses (TEM, EDX, ICP-AES, React-IR), reveal that catalysis using nickel-on-charcoal (Ni/C) is most likely of a homogeneous rather than heterogeneous nature. In the course of a reaction with Ni/C, nickel bleed from the support was calculated to be as high as 78%. However, the existence of an equilibrium for this homogeneous species between nickel located inside vs outside the pore system of charcoal strongly favors the former, thus leaving only traces of metal detectable in solution. This accounts for virtually complete recovery of nickel on the charcoal following filtration of a reaction mixture and allows for recycling of the catalyst. TEM and EDX data were used to explain different reactivity profiles of Ni/C, which depended upon the method of reduction used to convert Ni(II)/C to Ni(0) as well as the level of nickel loading on the support
