Abstract

This research is motivated by student mathematics learning outcomes on the material two-dimentional figure still low. The learning process is still teacher-centered and there is a lack of good cooperation between students in discussions when the learning process takes place. This research is an experimental study that aims to determine whether there are differences in student learning outcomes taught by cooperative models Think Pair share and learning models The conventional research design used is Nonrandomized Control Group Posttest Design. The population in this study were all eighth grade students of Ambon-Wathan High School with 100 students and the sample in this study was 40 students, selected using purposive sampling. The instrument used in this study was in the form of test questions which consisted of question details for the final test. The analysis used is statistical analysis, which is t-test. Calculation results obtained, namely the value of Sig. (2-tailed) < ? or 0.026 <0.05 which causes H0 to be rejected and H1 to be accepted. Based on the accepted hypothesis, the results of the study showed that there were differences in the learning outcomes of the experimental class and control class students who were taught with the Cooperative learning model of the Think Pair share type and the conventional learning model on the Material of Blocks and Beams

Abstract

Penelitian ini bertujuan untuk mengetahui ada tidaknya perbedaan hasil belajar siswa kelas VIII SMP Negeri 22 Ambon menggunakan model pembelajaran kooperatif tipe Make A Match dan model pembelajaran konvensional pada materi statistika. Tipe penelitian yang digunakan adalah tipe penelitian eksperimental (Experimental Research). Desain penelitian eksperimen yang digunakan adalah Post-Test Only Control Group Design. Teknik analisis dalam penelitian ini menggunakan analisis statistik deskriptif dan statistik uji inferensial yang terdiri dari uji normalitas data, uji homogenitas dan uji hipotesis. Data dalam pengujian tersebut diolah dengan menggunakan SPSS versi 25.0. Hasil penelitian menunjukkan bahwa terdapat perbedaan hasil belajar menggunakan model pembelajaran Make A Match dan model pembelajaran konvensional. Hal ini ditunjukan  dengan hasil atau data yang diperoleh yaitu nilai Sig. (2-tailed) lebih kecil dari nilai  yaitu 0.028

Abstract

[English]: This qualitative study with phenomenology design aims to investigate the use of backing and its relation to rebuttal and qualifier in prospective mathematics teachers? (PMTs) argumentation when constructing a mathematical proof about algebraic function. The data were collected through subjects' works on the proof, recorded think-aloud data, and in-depth interviews. Data analysis was guided by Toulmin?s argumentation scheme. The results show that the PMTs used three types of backing, i.e., backing in the form of definitions or theorems (reference backing), examples of numbers (numerical backing) and graphs of functions (graphical backing). The PMTs utilized the backings to strengthen deductive and inductive warrant. A numerical backing is used when a warrant cannot justify the truth of a claim. Graphical backing is used to convince oneself about the truth of the data that has been made while the reference backing is only clarification when students have understood or have knowledge of the statement given. Numerical and graphical backing relate directly to rebuttal and provide counter-examples and qualifier of the claim. A numerical backing makes students more confident about claims that are generated compared to reference backing. Keywords: Argumentation, Mathematical proof, Backing [Bahasa]: Penelitian kualitatif dengan desain fenomenologi ini bertujuan untuk menyelidiki penggunaan backing dan hubungannya dengan rebuttal dan qualifier dalam membangun bukti matematika terkait fungsi aljabar oleh calon guru matematika. Data dikumpulkan melalui hasil kerja siswa, rekaman think aloud, dan wawancara mendalam. Analisis data merujuk pada skema argumentasi Toulmin. Hasil penelitian menunjukkan bahwa backing yang digunakan siswa tidak hanya berbentuk teorema atau definisis (reference backing) tetapi juga contoh-contoh bilangan (numerical backing) dan grafik fungsi (graphical backing). Ketiga jenis backing tersebut untuk memperkuat warrant induktif maupun deduktif. Numerical backing digunakan ketika warrant tidak dapat menjustifikasi kebenaran klaim. Graphical backing digunakan untuk meyakinkan diri sendiri tentang kebenaran klaim yang telah dibuat sedangkan reference backing hanya bersifat klarifikasi karena siswa telah memahami pernyataan yang diberikan. Numerical backing dan graphical backing berhubungan langsung dengan rebuttal untuk memberikan contoh penyangkal dan jaminan kebenaran (qualifier) klaim. Numerical backing membuat siswa lebih percaya diri tentang klaim yang dihasilkan dibandingkan dengan reference backing. Kata kunci: Argumentasi, Bukti matematis, Backing

Abstract

Student learning achievement in statistical material is still relatively low, because the learning method used is still monotonous (conventional).  This study aims to improve the learning achievement of class XII Students of SMA Negeri 2 Salahutu on statistical material through the cooperative learning type two stay two stray. This type of research is a class action research consisting of two cycles, with each cycle consisting of two meeting. The subjects in this study were students of class XII-MIA2 with a sample of 20 students. Data collection techniques in this study were obtained from the results of observations and final test results of students in each cycle. Classical student learning outcomes from cycle I to cycle II increased by 15%. Based on results obtained, it can be concluded that using the cooperative learning of the two stay two stray type can improve the learning outcomes of class XII students of SMA Negeri 2 Salahutu on statistical matrial.
