In the fields of humanities and social studies, for example, philosophy, psychology, sociology, anthropology, etc., a so-called "practice turn" has taken place over the past 20 years. Many scholars have reviewed and criticized the limitations and deficiencies of the dominant traditional theories on learning, thinking, human behaviors, and social interaction, leading to a series of research and theoretical developments on how to analyze and investigate research issues related to practice. Based on, but going beyond the traditional theories, they were able to gradually develop a variety of theoretical accounts and research orientations pertinent to highlight the characteristics and features of practice. First, this article aims at introducing the recent developments of the "practice turn" in the field of humanities and social studies, including the theories of practice and the theory of practice architectures. Subsequently, based on the potential applications of these theoretical perspectives, the author puts forward an "Instructional Practice Model", which is meant to be applied as a reference for school teachers and university professors to carry out research studies on instructional practice.
