Pengembangan Perangkat Pembelajaran Matematika Model Discovery Learning Pada Materi Trigonometri Untuk Kelas X SMK/MAK Menggunakan Model Pengembangan Four-D
The research background is the importance of mathematics learning devices as a form of learning planning prepared by the teacher in order to achieve learning objectives, but the mathematics learning devices used by the teacher still have a mismatch with demands of the 2013’s curriculum. This research is aimed to produce a learning devices using the discovery learning model that is categorized as valid. The devices developed were the syllabus, lesson plans and student worksheets on trigonometry material (sine and cosine rules) for the tenth grade of vocational high schools. This research includes research and development. The development design used is the four-D model (define, design, develop and disseminate). The validity data of learning devices were collected through a questionnaire using a validation sheets. The learning devices developed were validated by three validators and evaluated by three vocational high school students to evaluate the readability of student worksheets. Based on the result of data analysis, it is concluded that the learning device developed is valid. The mathematics learning devices based on discovery learning model on trigonometry materials for the tenth grade of vocational high schools can be used as a support in the mathematical learning process.
