Development of Braille Module Using Problem Based Learning with the Help of Audio to Enhance Visually Impaired Students’Creative Thinking Skills on Mathematic
The aims of this research are to know: 1) process and product development of Braille module problem based learning with audio as a valid, practical and effective to enhance visually impaired students’ creative thinking skills on mathematics; 2) whether learning using Braille module is more effective or not than learning using ordinary module to enhance visually impaired students’ creative thinking skills on mathematics. This research and development uses 4D model by Thiagarajan which has modified in Focus Group Discussion. The data of this research are analyzed descriptively and statistically. Analysis of module’s quality is based on expert judgments, practically and effectiveness criteria score. Analysis of pretest-posttest of students’ creative thinking skills on mathematics used t-test (hypothesis testing). The results of this research are: 1) process of the development of the module was started with an analysis of problems and needs of visually impaired students to obtain the first draft module. The validation process was done by following up suggestions and revisions from the experts to produce a valid second draft. The results of the trial test can be concluded that the module is practical with the classification of the minimal percentage of the implementation in each meeting and effective based on the minimal percentage of the students’ response in every meeting of learning; 2) learning using Braille module more effective than learning using ordinary module to enhance students’ creative thinking skills on mathematics for visually impaired students.
