Development of online learning device based on demonstration models on heat transfer materials

Abstract

Whether we realize it or not, the faster and rapid development of technology has an impact on the faster and faster progress in the world of education. During the current covid-19 pandemic, much needed online learning tools, the concept of home-schooling has never been mainstream in the national education discourse. Because the teaching system has been changed through online learning, there is a need for the development of learning tools for teachers to be able to continue delivering material to their students. This study aims to develop online learning tools based on demonstration models on effective heat transfer material during the covid-19 pandemic. The development of this research uses the ADDIE model with stages of development: 1. Analysis, 2. Design, 3. Develop, 4. Implement, 5. Evaluate. Learning tools are made online to make it easier for teachers and students to carry out teaching and learning activities during online learning. Validation was carried out by 3 experts, namely media experts, material experts, learning experts and tested on students. The results of the analysis of the validation of material experts obtained an average percentage of 86.80 % in the very high category, the results of the analysis of learning experts obtained an average percentage of 88,70 % with a very high category, the results of the analysis of the media expert obtained a percentage of 86,70 % with a very high. The subject was tried in class XI high school. Data collection instruments using a questionnaire through the Google form. From the results of the development of online learning tools based on online demonstrations on heat transfer material obtained learning tools (Free Learning Implementation Plan, Worksheet and online media) have been tested for eligibility by experts and field trials with good criteria and are suitable for use.
