Development of online learning devices based on project based learning (PjBL) in optical materials

Abstract

In the twenty fisrt century Science and Technology (IPTEK) is developing very rapidly, including in the aspect of communication. This is closely related to everyday life because of the use of technology as a tool that makes human work easier. Long distance communication is commonplace in this era. Currently due to the COVID-19 pandemic, student learning is being carried out online using one of the online media, namely Google Meet. So with this technological advancement, learning can be done anywhere and anytime. The purpose of this study was to develop online lesson plan or lesson plans using the Project Based Learning (PjBL) learning model on optical materials. The method used is ADDIE (Analysis), Design (Design), Development (Development), Implementation (Implementation), and Evaluation (Evaluation). After going through the process of validation and testing on students, the results of the development of this learning device are valid so that they can be used
