The book "Training According to 4K" offers a comprehensive introduction to the four key competencies that are essential in the 21st century: critical thinking, problem-solving, communication, cooperation, creativity, and innovation. The author and contributors present an innovative study model for vocational education that has already been successfully implemented at the Zurich University of Teacher Education. This model aims to train future teachers in both vocational and general education collaboratively. Through practical examples, it illustrates how these competencies can be integrated into training to optimally prepare future educators for their roles in society. The book is a valuable tool for anyone involved in education and looking to promote the development of key competencies.
