Welcome to the first issue of the twelfth volume of the Journal of Problem Based Learning in Higher Education. This is our annual issue and contains 5 research papers and 3 case studies. The scope of the journal is nicely mirrored in the papers and cases, and the range of our mutual interest in the topic of PBL in Higher Education is showcased by the diversity of the papers and cases. Once again, our authors come from all over the world, Brazil, Denmark, Turkiye, Germany, Sweden, and the UK, and are focused on a variety of areas such as group assessment, supervision methods, organisational change, teacher training etc.
