<![CDATA[Abstrak: Kami telah melakukan eksperimen dengan bentuk desain pre-test dan post-test padakelas VIII SMP untuk melihat peningkatan hasil belajar melalui pembelajaran kooperatif. Instrumen yang digunakan berupa tes soal sebanyak 30 soal untuk masing-masing pre-test dan post-test. Berdasarkan hasil pengukuran hasil belajar pada kelas eksperimen diperoleh hasil pre-test sebesar 53,40 dan post-test sebesar 79,20 sedangkan pada kelas kontrol diperoleh hasil pre-test sebesar 55,83 dan post-test sebesar 73,33. Kemudian pada uji hipotesis dengan menggunakan uji-t diperoleh t-hitung = 2,202 dan t-tabel = 1,679 yang menunjukkan bahwa hipotesis diterima, sehingga dapat dikatakan bahwa ada pengaruh yang signifikan dari model pembelajaran kooperatif berbasis kegiatan Laboratorium terhadap peningkatan hasil belajar siswa. Abstract: We have conducted experiments in the form of pre-test and post-test designs in class VIII SMP to see improvement in learning outcomes through cooperative learning. The instruments used in the from of test questions were 30 questions for each pre-test and post-test. Based on the results of the measurement of learning outcomes in the experimental class, the results of the pre-test were 53.40 and the post-test was 79.20 while the control class obtained a pre-test result of 55.83 and the post-test was 73.33. Then on the hypothesis test using the t-test obtained t-count = 2.202 and t-table = 1.679 which shows that the hypothesis is accepted so it can be said that there is a significant effect of cooperative learning models based on Laboratory activities on improving student learning outcomes.]]>
