PENERAPAN MODEL PEMBELAJARAN KOOPERATIF TIPE JIGSAW DENGAN LKPD BERBASIS KASUS UNTUK MENINGKATKAN HASIL BELAJAR PENGETAHUAN SISWA

IMPLEMENTATION OF THE JIGSAW TYPE COOPERATIVE LEARNING MODEL WITH CASE-BASED WORKSHEET TO IMPROVE STUDENTS’ KNOWLEDGE LEARNING OUTCOMES

Hasil belajar dapat dijadikan sebagai tolok ukur untuk mengetahui seberapa jauh perubahan pada diri siswa setelah menerima materi pada proses pembelajaran. Tujuan dari penelitian ini untuk mengetahui adanya peningkatan hasil belajar pengetahuan siswa setelah diterapkannya model pembelajaran kooperatif tipe Jigsaw dengan bantuan LKPD berbasis kasus. Desain penelitian yang digunakan, yaitu one group pretest-posttest dengan partisipan yang terlibat sebanyak 30 siswa di salah satu kelas SMP di Sidoarjo. Teknik pengumpulan yang digunakan, yaitu observasi keterlaksanaan pembelajaran, tes tulis hasil belajar pengetahuan, dan survei respons siswa. Data yang sudah terkumpul kemudian dianalisis menggunakan normalized gain (<g>), visualisasi scatterplot,   Cohen’s Kappa coefficient (ĸ), dan persentase angket respons siswa. Nilai Cronbach’s Alpha (α) = 0,61 dan Mc Donald’s omega (ω) = 0,65 pada instrumen yang dapat diartikan reliabel karena ≥0,6. Hasil analisis <g> didapatkan 83% siswa mendapat skor <g> tinggi dan 17% siswa mendapat <g> sedang. Berdasarkan hasil-hasil tersebut meskipun terdapat limitasi, dapat disimpulkan bahwa model pembelajaran kooperatif tipe Jigsaw dengan LKPD berbasis  kasus dapat berdampak pada meningkatnya hasil belajar pengetahuan siswa.

Learning outcomes can be used as a benchmark to find out how far students have changed after receiving material in the learning process. The purpose of this study was to determine the increase in student knowledge learning outcomes after the implementation of the Jigsaw cooperative learning model with the help of case-based worksheets. The research design used was one group pretest-posttest with 30 students involved in one of the junior high school classes in Sidoarjo. The collection techniques used were observation of the implementation of learning, written tests of knowledge learning outcomes, and student response surveys. The data that has been collected is then analyzed using normalized gain (), scatterplot visualization, Cohen's Kappa coefficient (ĸ), and the percentage of student response questionnaires. Cronbach's Alpha (α) = 0.61 and Mc Donald's Omega (ω) = 0.65 values in instruments which can be interpreted as reliable because ≥0.6 The results of the analysis showed that 83% of students got a high score and 17% of students got moderate scores. Based on these results, although there are limitations, it can be concluded that the Jigsaw cooperative learning model with case-based worksheets can have an impact on increasing student knowledge learning outcomes.
