Pengembangan Perangkat Pembelajaran Matematika Menggunakan Model Pada Bangun Ruang Sisi Lengkung Kelas IX SMP/MTS Discovery Learning Pada Materi
This research is a development purposed is to produce mathematics
learning devices such as syllabus, lesson plans, and student worksheet by using
discovery learning on curved face three dimensional (cylinder, cone, and ball)
material for the 9th grade of junior high school. This research is motivated by the
incompatibility instruments which arranged by teacher based on 2013 Curriculum.
The development model used in this research is the 4-D model which consists of the
stages of define, design, develop, and disseminate. The instruments used in this
study were the validation sheet and student’s responce questionnaires. The learning
that have been developed were validated by three of the validation and revised
according by suggestions from the validators. The average score of the validation
results for the syllabus is 3,79, lesson plans is 3,81 and student worksheet is 3,73
with very valid categories. The result of this validation indicate that the syllabus,
lesson plans, and student worksheet are feasible to be tasted. Student worksheets
that has been valid is then tried out in small group. The average percentage of the
small group trial results of student worksheets is 92,29% with very pratical
category. Based the results of data analysis and discussion it can be concluded that
syllabus, lesson plans, and student worksheet by using discovery learning on curved
face three dimensional material for the 9th grade of junior high school has fulfilled
valid.
