The Enhancement of Teaching-Learning Process Effectiveness through The Development of Instructional Media Based on E-learning of Surabaya's Vocational Student

In the context of e-learning, many learning theories used in the physical classroom situation, including learning in a community adaptive, collaborative, scaffolding, and scenario learning, have been adopted and validated, The development of instructional media has been built used the adoption of responsive web design techniques developed by the modern web markup language HTML5 and CSS3 style formatting pages while bootstrap frame work was used to build e-learning. A deep analysis of learning effectiveness done in the instructional media based on e learning. The instructional media was applied on vocational high school. Research and Development method was used in this study. The following development procedures were arranged: planning, design, and development phases. In the development phase, on-going evaluation was carried out until a preliminary product was materialized. The result of instructional media based on e-learning development underwent three experimentation phases. In the first experimentation, a media and material experts' validation, were executed. In the second experimentation, through individual experimentation and small group experimentation involving teacher and students (clients) were carried out up to the final phase revision. In the third experimentation, the product validation, also known as summative test, was obtained from extensive field experimentation to discover the effectiveness of the instructional media based on e-learning in a real teaching process using elearning model. This web based e-learning system provided electronic, illustration, group learning, comprehension, and workshop learning units and complied with the training objectives of the designated course. The validation of this model was positive and the results indicated that the proposed web based e-learning course could be further improved by taking into consideration individual learners’ attributes.
