The Development Of Interactive Mathematics Multimedia About Circle With Contextual Teaching And Learning Approach For Student Grade 8 Junior High School

摘要

The quality of learning mathematics can be promoted through the application of learning strategies and supported by using appropriate learning media. This research objective is to produce interactive multimedia with contextual teaching and learning approach on the subject of circle in class VIII. The research method used is development research which involves several main steps, as follows: 1) developed products need analysis, 2) developing the initial product, 3) expert validation and revision, 4) small-scale field trials and product revision, 5) large-scale field trials and the final product. Research trials for need analysis conducted at class IX of a public junior high school in Jakarta involving 60 students who have passed materials class VIII and two mathematics teachers. One of the materials that are considered to be difficult for the students is circle. Respondents assumed the mathematics subject needs to be connected with real life situation and they would be interested in learning mathematics using interactive multimedia. Based on the result of need analysis, initial product is developed by using software Adobe Flash. The next step is expert validation involves material, language, and learning media judgements. At this step, inputs and suggestions are received to a revised initial product. After that, small-scale and large-scale field trials are conducted at class VIII of a public junior high school in Jakarta involving 12 and 60 students, respectively. According to the result of expert validation and field trials, it can be concluded that the interactive multimedia developed has propered to be disseminated and used as mathematics learning media at school
