TINGKAT VALIDITAS MEDIA PEMBELAJARAN CCR (COLLOID CHEMISTRY ROLL) BERBASIS ELEKTRONIK
Based on the result of the interview, the classical completeness colloidal matter was below the average of about 60%. It can happen because in the learning process have not used media yet in the colloidal matter, so that student tend to memorize without understood the matter and led to low motivation of student. Teacher and students argued that they were very interest to the instructional media such as games. Therefore, it was necessary to develop electronic based CCR instructional media to increased the motivation of student in the learning process. This study aimed to determine the level of feasibility of electronic-based CCR instructional media. The research method used the ADDIE development model which consists of 5 stages, it was analysis, design, development, implementation and evaluation. The level of feasibility was known by measuring validity using a questionnaire that distributed to a media expert validator and a material expert validator. The research subjects were a chemistry teacher and 36 students from XI MIPA SMAN 1 Tanjungpinang. The type of the research data was qualitative data in the form of words, schematics and images and quantitative data were in the form of numbers. The results of the material expert validity were 98.4% with a very valid category and media expert were 78.34% with a valid category. So it can be concluded that the electronic-based CCR instructional media can for used in learning chemistry.
