This book discusses activity-based collaborative active learning (CAL) approaches in connection with the learning and teaching of STEM and non-STEM disciplines. It also covers feedback and assessment activities as learning activities supported by learning technologies and applied in appropriate learning spaces. The contributing authors discuss in detail the implementation and facilitation of activity-based CAL strategies, the problems encountered and corresponding mitigation measures. In addition, all activities are developed in a blended mode, making them suitable for readers at any level of education who are interested in trying out CAL. Covering both STEM and non-STEM disciplines, this book offers comprehensive guidelines for lecturers who are interested in active learning.
