<![CDATA[This research purpose was to know the influence of TPS learning modeltowards student activities and conceptual understanding. The research used non-equivalent pretest posttest design. The samples were students of VIIG and VIID class that were selected by purposive sampling technique. Qualitative data were obtained from learning activities observation sheets and students questionnaire responses that were analyzed descriptively. Quantitative data were obtained from the average value of test that were analyzed by using t-test and U-test. The average of students learning activities percentage for all aspects in experiment class was higher than control that was 45.60%. The average of conceptual understanding in experiment class was higher than control. Most of the student (93%) gave good impression towards TPSlearning model. Therefore, TPS cooperative learning model improved students activities and conceptual understanding on subject of the characteristics of living things.Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran kooperatif Think Pair Share (TPS) terhadap aktivitas belajar siswa dan penguasaan materi. Desain penelitian menggunakan pretes-postes tak ekuivalen. Sampel penelitian siswa kelas VIIG dan VIID yang dipilih menggunakan metode purposive sampling. Data kualitatif diperoleh dari lembar observasi aktivitas belajar dan angket tanggapan siswa terhadap penerapan model pembelajaran kooperatif TPS yang dianalisis secara deskriptif. Data kuantitatif diperoleh dari rata-rata nilai tes dianalisis menggunakan uji-t dan uji-U. Rata-rata persentase aktivitas siswa semua aspek pada kelas eksperimen menunjukkan peningkatan yang lebih tinggi sebesar 45,60% dibanding kelas kontrol. Hasil penelitian menunjukkan bahwa penguasaan materi pada kelas eksperimen lebih tinggi dibanding kelas kontrol. Sebagian besar siswa (93%) memberikan tanggapan positif terhadap model pembelajaran TPS. Dengan demikian, penggunaan model pembelajaran kooperatif TPS meningkatkan aktivitas belajar dan penguasaan materi pokok ciri-ciri makhluk hidup.Kata kunci : aktivitas belajar, ciri-ciri makhluk hidup, model pembelajaran TPS, penguasaan materi]]>
