Research-Based Biotechnology Book with Virtual Laboratory for Elevating TPACK of Biology Pre-Service Teacher

Abstract

This study aims to determine the development of Technological Pedagogical and Content Knowledge (TPACK) biology education pre-service teachers using research-based biotechnology book equipped with a virtual laboratory. This research was conducted at the Biology Education Program-University of Jember, which involved 32 pre-service teachers who took the biotechnology course. This research applied Reflective, Recursive, Design, and Development (R2D2) design model and paired sample t-test to figure out differences between before and after using the developed product. The validation process involved six experts of content, media development, and user. The results of the book and virtual laboratory validation showed an average value of 86.17%, which is classified as a very valid category. The pre-service teacher response revealed an excellent value of 80.58%. Subsequently, a biotechnology book and virtual laboratory were used to test the TPACK competencies level of biology pre-service teachers. The paired sample ttest

results showed 0,000 values, which means there were significant differences before and after the use of the research-based book and virtual laboratory developed. To summarize, a research-based biotechnology book equipped with a virtual laboratory can increase TPACK of biology pre-service teachers and recommend them as tools to teach biotechnology.
