Pengembangan E-Modul Berbasis Multipel Representasi Dengan Bantuan Teknologi Augmented Reality untuk Pembelajaran Materi Bentuk Molekul

Abstract

The integration between the three levels of chemical representations is needed by students to get a comprehensive understanding. Based on the preliminary study only 45.5% out of 120 year 2 and year 3 students of chemistry education who passed the final exam with satisfactory category. Thus, teaching resources that integrate the three levels of chemical representation are needed. The aim of this study is to develop and determine the level of validity of e-module utilizing multiple representations of molecular shapes based on VSEPR theory using augmented reality technology. This research employs research and development refers to the instructional design of the ADDIE model consist of 5 stages: Analyze, Design, Develop, Implementation and Evaluation. The products of this research are the e-module of molecular shapes based on VSEPR theory utilizing multiple representations and Augmented Reality Molecule Simulator (ARMOR) application. The resources presented 13 types of molecular shapes, molecules with lone pair and without lone pair of electrons around the central atom. The instrument used in this study is the validity questionnaire sheet. Data collected were then analyzed using the percentage criteria proposed by Akbar. The results of the experts’ validation indicated that the product is categorized as very valid with 94% of content validity, 93% of media validity, and 99% of language validity. Therefore, the ARMOR is suitable for use in teaching and learning process. Students show a positive response to the use of the application in helping them understand concepts, which are easy to use, has an attractive appearance, and fun.

Developing an Augmented Reality-Assisted E-Module Based on Local Wisdom of Pedicabs for Physics Teaching

“…The result of the study shows the developed augmented reality-assisted physics e-module based on the local wisdom is suitable for use in physics teaching and learning. This is in line with several previous studies conducted by (Hurrahman et al, 2022;Yulkifli et al, 2022). The developed augmented reality-assisted physics e-module based on the local wisdom is feasible to be used as a complement to learning for students, and it can be used anywhere and anytime.…”

Development of Electronic Learning Chemistry Assessment Applications Through Project-Based Learning for Increasing Student Scientific Performance

“…In addition, based on research conducted by Ramlawati, et al (2014) that the implementation of electronic assessment such as portfolios has a positive influence on improving students' generic skills, especially in explaining symbolic language, visual spatial and chemical modeling. In addition, the existence of learning methods using technology is able to solve learning problems and is able to stimulate visual representation abilities, symbolically and student learning motivation (Hurrahman, et al, 2022).…”

Pengembangan Aplikasi Interaktif Berbasis Inkuiri Terbimbing Materi Hidrolisis Garam

“…Dalam memecahkan masalah yang terjadi pada proses belajar mengajar seperti menurunnya motivasi belajar, dan konsep materi yang abstrak, di sinilah peran penting penggunaan teknologi dalam proses pembelajaran. (Hurrahman et al, 2022).…”
