Learning is a changing phenomenon, depending on the advances in theory and research. This book presents a relatively new approach to learning, based on meaningful human activities in cultural practices and in collaboration with others. It draws extensively from the ideas of Lev Vygotsky and his recent followers. The book presents ideas that elaborate this learning theory and also gives recent developments and applications of this approach in a variety of educational situations in and outside of school. A core issue in the research presented in this book consists of the way people learn to make sense of and give meaning to cultural instruments and practices in collaboration with others.
