Prototyping Phase in the Development of Character Building in Integrated Tematic of Teaching Materials Based on Discovery Learning in 4th Grade of Elementary School

Abstract

Character building value in current teaching materials is still at the notification stage. It means that this materialstill doesn’t provide the opportunities for students to feel and to replicate those charactervalues in teaching learning process. Therefore, it is necessary to develop the teaching materials that are arranged based on learning model supporting student activeness that is discovery learning. Developed teaching materials should have the good criteria such as valid, practical and effective. The purpose of this study is to determine the level of validity and practicality of teaching materials developed. This research method uses a Mc Kenney’s development model, which is devoted to stage 2, namely: prototyping phase: expert test and practice test by students and teachers. Based on the results of the validity test obtained data that teaching materials based on character building with the discovery learning modelare in the category of valid with an average score of 3.7 and it is in a category very valid. Furthermore, the stage of practicality is done by giving questionnaire to teachers and students. The score of the teacher’s response 77.3% (practical) and the score of the students’ response is 85.83% (very practical).
