Developing User-Friendly E-module Hyper-content on Atomic Structure and Periodical Properties of Elements

Abstract

Abstract Connecting understanding on atomic structure to explain the periodical properties of elements has always been a challenge over the years. One of the factors behind this is the lack of availability of syllabus-relevant, user-friendly, practical and accessible learning resources on the topics. Therefore, this research and development study aims to produce a valid and practical e-module hyper-content to support the learning process of structure atom and periodical properties of element by preservice science teachers. The e-module was developed through ADDIE model which consists of five stages namely Analysis, Design, Develop, Implementation, and Evaluation. The validity test of the product was conducted through expert judgements and the practicality test was conducted involving 110 third semester students of Science Education Department of Universitas Negeri Padang. Result of the feasibility test indicated that the e-module with hyper-content on structure atom and periodical properties of elements belongs to very high category for both validity and practicality. Analysis of students’ responses on open-ended questionnaires revealed that this e-module is beneficial for better learning on the topic due to the ease of use and integrative way of presenting information on relevant topics.
