Taking into account the various types of knowledge required by teachers and how they may grow this knowledge, the TPAC.K framework provides a fruitful tool to consider how teachers can integrate educational technology into the classroom. Furthermore, TPACK can be used to assess teacher knowledge, potentially impacting both training and professional development opportunities for teachers of all levels of expertise. The TPACK framework is also valuable because it explains the categories of knowledge that are most important for successful technology integration in the classroom. Teachers do not even need to be conversant with the complete TPACK framework to benefit from it: they simply need to realize that content-driven, pedagogically sound, and technologically advanced instructional practices shape the best instructional practices. This book is intended to provide readers particularly teachers with an overview of TPACK (Technological Pedagogical Content Knowledge) such as definition of TPACK, Components of TPACK, and Evolution of TPACK. The Effective Educational Technology and teaching with technology are also provided to enhance teachers’ awareness of the importance of integrating technology in the classroom. The steps to Lessons Planning are also given in this book to assist teachers in designing TPACK Lesson Plans as currently, students are close to technology. That is why the better the teacher's mastery of TPACK, the better the quality of the lesson plans produced. In this way, learning objectives can be achieved. Diffusion Theory and SAMR Model are provided as a simple framework for effectively evaluating technology in order to maximize its potential and empower student learning. The last, the research results of a study are reported as TPACK in practice to show the readers the TPACK levels and the TPACK occurrences in the classroom.
