Abstract

ABSTRAKPenelitian ini adalah penelitian eksperimen semu yang bertujuan untuk mengetahui pengaruh strategi think talk write pada model pembelajaran problem based learning terhadap keterampilan berpikir kritis siswa Kelas XI MS SMA Negeri 2 Bulukumba. Variabel bebas dalam penelitian ini adalah strategi think talk write pada model pembelajaran problem based learning dan variabel terikatnya adalah keterampilan berpikir kritis siswa pada materi pokok laju reaksi. Populasi penelitian ini adalah siswa kelas XI MS SMA Negeri 2 Bulukumba. Teknik pengambilan sampel yaitu random sampling. Sampel penelitian terdiri dari 2 kelas yaitu kelas XI MS2 sebagai kelas eksperimen dengan jumlah siswa 37 orang dan kelas XI MS3 sebagai kelas kontrol dengan jumlah siswa 39 orang. Instrumen yang digunakan pada penelitian ini yaitu lembar observasi untuk mengetahui aktivitas siswa dan tes keterampilan berpikir kritis siswa untuk mengetahui keterampilan berpikir kritis siswa. Data hasil penelitian diperoleh dengan menilai aktivitas keterampilan berpikir kritisnya selama proses pembelajaran dan memberikan tes keterampilan berpikir kritis pada materi pokok laju reaksi berupa post-test yang dianalisis menggunakan uji-t. Hasil analisis statistika inferensial diperoleh thitung (5.33) >ttabel (1,67) pada ????═ 0,05. Disimpulkan bahwa strategi think talk write pada model pembelajaran problem based learning berpengaruh terhadap keterampilan berpikir kritis Siswa Kelas XI MS SMA Negeri 2 Bulukumba pada materi pokok laju reaksi.Kata Kunci : Think talk write, Problem based learning, Keterampilan berpikir kritis, Laju reaksiABSTRACTThe research was a quasi-experimental that aimed to know the effect of think talk write strategy on problem based learning model toward student’s critical thinking skill of class XI MS SMA Negeri 2 Bulukumba. The independent variable in this experiment was Think Talk Write Strategy on problem based learning model and the dependent variable was student’s critical thinking skill on reaction rate subject matter. The population was class XI MS SMA Negeri 2 Bulukumba. Taking technique of sample was random sampling. The sample of this research consisted of two classes, namely class XI MS2 as a experiment class with 37 students and class XI MS3 as a control class with 39 students. Instrument in my research are observation sheet to know the activity of student and test of critical thinking skill to know the critical thinking skill student. The data of the research were gathered by valuated critical thinking skill activity during learning in class room and testing the students’ critical thinking skill on reaction rate subject matter for post-test which were analyzed by using t-test. Results of inferential statistical analysis were tcalculated (5.33) higher than ttable (1,67) on α ═ 0,05. Conclude that think talk write strategy on problem based learning model gives effected toward student’s critical thinking skill of class XI MS SMA Negeri 2 Bulukumba on reaction rate subject matter.Keywords: Think talk write, Problem based learning, Critical thinking skill, Reaction rate

Abstract

ABSTRAKPenelitian ini bertujuan untuk mengetahui langkah-langkah penerapan pembelajaran peta konsep setting kooperatif tipe TAI yang dapat meningkatkan aktivitas belajar siswa kelas XI MIA1 SMA Negeri 7 Bulukumba. Penelitian ini merupakan penelitian tindakan kelas yang dilakukan dalam dua siklus, masing-masing siklus pembelajaran meliputi perencanaan, pelaksanaan, pengamatan, dan refleksi. Adapun langkah-langkah yang tepat dalam penerapan peta konsep setting kooperatif tipe Team Assisted Individualization (TAI) yaitu (1) guru membagi siswa menjadi 6 kelompok secara heterogen, (2) guru menjelaskan pokok-pokok materi dengan metode tanya jawab dan pemberian hukuman kepada siswa yang tidak dapat menjawab, (3) setiap siswa membuat peta konsep dan menyiapkan minimal satu buku bacaan, (4) siswa mengerjakan LKS dengan soal yang berbeda dalam satu kelompok, (5) siswa berdiskusi mengenai jawaban dari soal LKS (6) guru memberi pengajaran kepada setiap kelompok dengan batasan waktu tertentu untuk setiap kelompok, (7) guru menunjuk siswa secara acak untuk mempersentasikan hasil diskusi kelompok, (8) guru memberikan kuis dengan bentuk soal yang berbeda tiap anggota kelompok, (9) guru menunjuk siswa secara acak untuk menuliskan jawaban kuis di papan tulis, dan (10) guru meminta setiap siswa menuliskan kesimpulan materi pelajaran. Data hasil penelitian menunjukkan aktivitas siswa disiklus I sebesar 67,58% dan siklus II sebesar 78,63%, artinya terjadi peningkatan aktivitas siswa sebesar 11,05%. Adapun hasil belajar siswa di siklus I sebesar 36,66% dan siklus II sebesar 71,88%, artinya terjadi peningkatan hasil belajar siswa sebesar 35,22%. Berdasarkan data hasil penelitian tersebut menunjukkan bahwa penerapan peta konsep setting kooperatif tipe TAI dapat meningkatkan aktivitas belajar siswa Kelas XI MIA1 SMA Negeri 7 Bulukumba.Kata Kunci: Kooperatif Team Asissted Individualization (TAI), peta konsep aktivitas belajar, termokimiaABSTRACTThe research aimed to describe learning steps of concept mapping cooperative setting type TAI to improve students’ activities Class XI MIA1 SMA Negeri 7 Bulukumba. The research was classroom action research which was done in two cycles and each learning cycle included of planning, implementation, observation, and reflection. The steps in implementing concept mapping with cooperative setting type Team Assisted Individualization were: (1) teacher divided the students into six groups heteregenously, (2) teacher explained the main materials by question and answer method and giving punishmennt to students who are unable to answer the equestions, (3) each students make concept mapping, at least one topic of material, (4) students answer the worksheet of different question in each group, (5) students discussion about the answer of worksheet question, (6) teacher gave lesson to each group with in certein limited time, (7) teacher appointed students randomly to present the group discussion result, (8) teacher gave quiz to each group by giving different types of question, (9) teacher appointed students randomly to write down the answer for quiz on the board, and (10) teacher asked each student to draw conclusion of the material subject. The data result of research showed the students’ activities in Cycle I was 67,58%and in Cycle II was 78,63%, which indicated improvement of students’ activities as much as 11,05%. The students’ learning output in Cycle I was 36,66% and Cycle II was 71,88%, which indicated improvement of students’ activities as much as 35,22%. Based on the result, the implementation of mind mapping cooperative setting type TAI had improved students’ activities in Class XI MIA1 SMA Negeri 7 Bulukumba.Keywords: Cooperative Team Assisted Individualization (TAI), mind mapping, learning activities, thermochemical
