Development of e-learning teaching material with augmented reality based on problem based learning for nature of chemistry and scientific methods topic as teaching material in Covid-19 pandemic

In 2013 curriculum, learning chemistry was designed to build thinking skills through a scientific approach Students are supposed to apply what they learn in oder to solving problems in daily life In supporting learning activities, a teacher needs teaching material The teaching material need to be arranged according to the needs of students and curriculum One of them is by preparing teaching materials using learning models, namely problem based learning During covid-19 pandemic, learning was done by online Innovation in online or digital-based teaching material is needed to support online learning from home such as integrating teaching material into e-learning Augmented reality can be added in teaching material to help visualize chemical particulate objects This study aims to produce e-learning teaching materials that are arranged by using Problem Based Learning model and equipped with Augmented Reality for topic nature of chemistry and scientific methods, as teaching materials in covid-19 pandemic that is affecting Indonesia nowadays This study uses the Lee & Owens development model until the development stage Feasibility of learning material seen from the results of the validation test and legibility test The results of material validation was 92 5% The results of the media validation obtained a score 95% Readability test results obtained a percentage of 86% Based on these results, teaching material that had been developed can be used to support learning nature of chemistry and scientific methods © 2021 Author(s)
