Discord-Based Flipped Guided Inquiry Learning: An Innovative Model for Periodic Table

The periodic table is chemistry material that must be learnt by students as a foundation to improve their knowledge of chemistry, if students find it difficult to understand the periodic table of elements, it will be very difficult for them to understand subsequent topics. The application of the flipped guided inquiry learning model can improve student learning outcomes. The purpose of this study is to develop and determine the validity and practicality of the Flipped Guided Inquiry Learning (FGIL) based learning system using the Discord application on the material of the periodic system of elements. In this study, the type of research applied is development research, namely Educational Design Research or EDR with the Plomp model which consists of 3 phases, namely Preliminary research, Development or Prototype phase, and Assessment Phase. This research is limited to the development and prototyping stages.  The research results on content validation obtained a valid product with an average of 0.90, with content validation assessments for the content component scoring 0.90, the presentation component value 0.91, the language component value 0.91, and the graphic component value 0.88. Meanwhile, the construct validation was 0.91 with a valid category; the display component value 0.90 and the ease component value 0.91. The practicality from teachers obtained 97% with a very practical category, while from students the result was 89% with a very practical category, thus resulting in a valid and practical flipped guided inquiry learning (FGIL)-based learning system product using the Discord application on the periodic table of elements material.
