摘要：Penelitian ini bertujuan untuk memperbaiki proses dan kualitas pembelajaran mata
kuliah program linear mahasiswa semester IV Program Studi Pendidikan Matematika
melalui Lesson Study. Penelitian ini merupakan penelitian deskriptif, dengan tujuan
untuk mendeskripsikan hasil observasi/pengamatan akivitas mahasiswa dan dosen.
Kegiatan Lesson Study dilakukan sebanyak dua kali open class, masing-masing open class
terdiri dari tiga tahap kegiatan yaitu: perencanaan (plan), pelaksanaan, (do), dan refleksi
(see). Pembelajaran dilakukan melalui penerapan model kooperatif. Hasil yang
diperoleh dalam penelitian ini adalah: meningkatkan aktivitas mahasiswa dengan
penerapan model kooperatif pada mata kuliah program linear, meningkatkan
pemahaman mahasiswa dalam mengerjakan masalah maksimasi dengan metode
simpleks, interaksi antar mahasiswa dalam pembelajaran meningkat. Berdasarkan
hasil di atas dapat disimpulkan bahwa model pembelajaran kooperatif pada mata
kuliah program linear dalam kegiatan lesson study dapat meperbaiki proses dan
kualitas pembelajaran.
其他摘要：The research aims to improve the process and quality of learning linear program at the fourth
semester students of the Mathematics Education Study Program through Lesson Study
activities. This research is descriptive research to describe the observation results of the students
and lecturers activities. Lesson Study activities were conducted in two times open classes, each
open class consisted of three activity phases, namely: planning (plan), implementation (do), and
reflection (see). Learning was conducted through implementation of cooperative learning
models. Based on the findings, it is recognized that the lesson study activities improve the
students’ activities through the implementation of cooperative model in the linear program
subject, improve students’ understanding in maximizing problems with the simple method, and
improve the interaction among the students. Based on those findings, it can be concluded that
the cooperative learning model in the linear program subject through lesson study activities can
improve the process and quality of learning.
