Abstract

Penelitian ini bertujuan untuk mengetahui peningkatan kemampuan pemecahan masalah matematika siswa melalui model pembelajaran LAPS-Heuristic. Jenis penelitian ini yaitu penelitian deskriptif kualitatif. Subjek dalam penelitian ini dipilih dua siswa dari kelas penelitian yaitu kelas X SMAN 2 Batang Anai. Subjek yang dipilih dalam merupakan siswa yang memiliki kemampuan matematika tinggi. Data dikumpulkan melalui tes pemecahan masalah dan wawancara. Hal ini dilakukan sebelum dan sesudah penerapa model pembelajaran LAPS-Heuristic. Berdasarkan hasil deskripsi dan analisis data, dapat dilihat perkembangan kemampuan pemecahan masalah matematika siswa meningkat pada saat dilakukan tes akhir. Pada hasil penilaian berdasarkan rubrik pemecahan masalah matematika, diperoleh tingkat kategori sangat memuaskan dengan indikator pencapaian: memahami soal dengan benar, rencana strategi penyelesaian yang benar, mengarah pada jawaban yang benar dan adanya pengecekan kembali hasil perhitungan, sehingga dapat disimpulkan bahwa model pembelajaran LAPS-Heuristic berpengaruh terhadap kemampuan pemecahan masalah matematika siswa kelas X SMAN 2 Batag Anai. Kata kunci: kesulitan matematika, pemecahan masalah, LAPS-Heuristic This research aims to determine the increase in mathematics problem solving ability of students through learning model LAPS-Heuristic. Type of research is a qualitative descriptive study. The subjects in this study were selected two students from class research that is class X SMAN 2 Batang Anai. Subjects selected were the students who have high math skills. Data were collected through a problem-solving test and interview. This data collection was done before and after the implementation of learning model LAPS-Heuristic. Based on the description and analysis of the test, it can be seen that the development of mathematical problem solving ability of students increased at the time of the final test. The results of the assessment under the rubric of mathematical problem solving, showcased very satisfactory level categories with indicators of achievement: understand the question correctly, the correct completion of strategic plans, leading to a correct answer and rechecking their calculation. Hence, it can be concluded that the model of LAPS-Heuristic affects the ability of Mathematical Problem Solving of Tenth Graders at SMAN 2 Batag Anai.

Abstract

Penelitian eksperimen dengan randomized control group only design yang melibatkan siswa kelas VIII SMPN 1 Batang Anai dilakukan untuk mengetahui pengaruh Pendekatan Matematika Realistik (PMR) terhadap kemampuan komunikasi matematis siswa. Teknik random sampling digunakan untuk menentukan kelas sampel. Kelas VIII3 terpilih sebagai kelas eksperiment dan Kelas VII6 terpilih sebagai kelas control. Hasil analisis data menunjukkan RME memiliki pengaruh yang signifikan terhadap kemampuan matematis siswa. Hasil Uji-t berada pada wilayah penokkan Ho, dimana thitung = 2,27 dan ttabel = 1,6603 pada taraf nyata 0,05. Analisis mendalam dilakukan dengan melihat efektivitas RME terhadap kemampuan komunikasi matematis dengan menggunakan uji proporsi (uji- z) pada setiap indicator yang diamati, menunjukkan hasil yang sejalan dengan hasil analisis uji-t.

Abstract

This study aims to understand better student errors in solving mathematics word problems. A Word problem is a problem that has a story or arrangement based on sentences. The qualitative research approach was used. The data were collected by giving tests and interviewing two male high achievers senior high school students in mathematics. The student error analysis adopted the Newman error analysis system. The source triangulation was used to ensure the data validity. Based on the collecting data and data analysis, the decoding/reading error happened caused by students' common understanding or unfamiliarity of the mathematical terms used in the problem. The subjects showed inconsistency in interpreting problem sentences and misused mathematical symbols. Furthermore, the subject encountered difficulties with the arithmetic process, especially fractions and their operation. This research identified students' difficulties in solving problem mathematics word problems. Moreover, this research provides evidence that encourages further research on mathematical literacy, mathematical communication skills, students' arithmetic skills, and the evaluation process of the problem-solving activity.

Abstract

The Students’ mathematics learning outcomes of is still under the expected score. This condition is caused by the lack of students’ anthusiasm, students’ involvement in learning process. Research in applying Carousel Technique and Each One Teach One Technique have resulted a positive effect to students learning outcomes. These models motivate students to express their ideas, works independently and develop their creativity in solving the given problem. This research aims to compare the effectiveness of both technique. The randomized post test only comparison group design is used in the research. The population is all of students of grade 10th of SMAN 5 Pariaman in year 2015/2016. Two classes are chosen as samples. The annava t-test and SPSS software are used to test the hypothesis. Based on the data, is obtained. Since , it means that is rejected. It can be concluded there is significant differences between students’ learning outcome that is taught with applying Carousel Technique and students’ learning outcome Each One Teach One Technique.

Abstract

Materi peluang merupakan salah satu topik dalam kurikulum matematika jenjang SMP yang memiliki keterkaitan erat dengan situasi dalam kehidupan sehari-hari. Namun demikian, berbagai hasil penelitian menunjukkan bahwa siswa masih mengalami kesulitan dan kerap melakukan kesalahan dalam menyelesaikan soal-soal yang berkaitan dengan peluang. Salah satu faktor yang diduga memengaruhi rendahnya kemampuan siswa dalam menyelesaikan masalah peluang adalah rendahnya kepercayaan diri siswa terhadap kemampuannya sendiri. Di samping itu, pendekatan dan model pembelajaran yang digunakan di kelas juga berperan penting dalam mengembangkan kemampuan pemecahan masalah matematis siswa. Sehubungan dengan hal tersebut, diperlukan penelitian lebih lanjut untuk mengkaji efektivitas model pembelajaran yang dapat meningkatkan kemampuan pemecahan masalah sekaligus memperhatikan aspek afektif siswa, khususnya self-confidence. Penelitian ini bertujuan untuk menganalisis keefektifan model pembelajaran flipped classroom berbasis pendekatan saintifik terhadap kemampuan pemecahan masalah matematis peserta didik pada materi peluang, ditinjau dari tingkat self-confidence peserta didik. Penelitian ini melibatkan peserta didik kelas VIII di MTI Pariangan. Hasil analisis menunjukkan bahwa pembelajaran dengan model flipped classroom yang dikombinasikan dengan pendekatan saintifik secara signifikan efektif dalam meningkatkan kemampuan pemecahan masalah matematis peserta didik. Selain itu, ditemukan bahwa peserta didik dengan tingkat self-confidence yang tinggi menunjukkan kemampuan pemecahan masalah yang lebih baik dibandingkan peserta didik dengan self-confidence yang rendah. Temuan ini mengindikasikan adanya hubungan positif antara self-confidence peserta didik dan kemampuan pemecahan masalah matematika dalam konteks pembelajaran flipped classroom berbasis pendekatan saintifik.
