VALIDITAS MEDIA LABORATORIUM VIRTUAL BERBASIS ANDROID PADA MATERI TITRASI ASAM BASA

Abstract

During distance learning, chemistry learning activities in the skills aspect have not been carried out with optimally. An imbalance between aspects of knowledge and skill in the chemistry learning process, it will be an obstacle in achieving learning objectives. The aimed of this research was to determine the validity of virtual laboratory media based on android on acid-base titration material. This type of research was used in Research and Development (R&D) with Hannafin and Peck's development model. The results of the validity of media expert and material expert on virtual laboratory media based on android on acid-base titration material obtained percentages of 85% and 90% with very valid categories and deserved to be tested on chemistry teacher and students. Based on the research results obtained, it can be concluded that the virtual laboratory media based on android on acid-base titration material developed is very valid to use in the learning process.
