Pengembangan Lkpd Berbasis Model Discovery Learning Pada Konten Lingkaran Untuk Memfasilitasi Kemampuan Berpikir Kritis Matematis Siswa Fase D
The purpose of this development research is to produce discovery
learning-based LKPD that can facilitate the mathematical critical thinking skills
of phase D students by fulfilling valid and practical requirements. The
background of the research begins with the importance of students' critical
thinking skills. This research method is a development research (R&D) with the 4-
D model (define, design, develop, and dessiminate). The test subjects involved 15
students of Babussalam Junior High School Pekanbaru. The research instrument
used a validation questionnaire sheet as a tool in assessing the validity of the
LKPD and a student response questionnaire as a tool in assessing the practicality
of the LKPD. Based on the analysis of the validation sheet by the expert validator,
the validity score of 94.43% of the LKPD criteria is very valid. Meanwhile, the
practicality score of LKPD from the response questionnaire is 87.98% very
practical criteria. Therefore, the development of discovery learning-based LKPD
is recommended to be utilized in learning circle content to facilitate critical
thinking skills of phase D students.
