Abstract

This research is motivated by the low ability of students to understand mathematical concepts. The Auditory Intellectually Repetition (AIR) learning model can be used as an innovative teaching solution in improving the ability to understand concepts because the Auditory Intellectually Repetition (AIR) learning model is a learning model that emphasizes three aspects, namely learning by listening, learning by thinking and repetition. This study aims to determine the effectiveness of the Auditory Intellectual Repetition (AIR) learning model in improving students' understanding of mathematical concepts. The design of this research is Pre Experimental with the form of research used is One Group Pretest-Posttest Design. The sampling technique used is Simple Random Sampling. After the samples were taken randomly, class X IPA 2 was chosen as the experimental class. The instrument in this study was in the form of a student's mathematical concept understanding ability test. The data analysis technique in this study used N-Gain data and the Paired Sample T Test (t test). Based on the average N-Gain value, it can be concluded that the Auditory Intellectual Repetition (AIR) learning model is effective in improving students' mathematical concept understanding abilities. Penelitian ini dilatarbelakangi oleh masih rendahnya kemampuan pemahaman konsep matematis siswa. Model pembelajaran  Auditory Intelletually Repetition (AIR) dapat dijadikan suatu solusi pengajaran yang inovatif  dalam meningkatkan kemampuan pemahaman konsep karena model pembelajaran Auditory Intellectually Repetition (AIR) merupakan model pembelajaran yang menekankan tiga aspek, yaitu belajar dengan mendengar, belajar dengan berfikir dan pengulangan.  Penelitian ini bertujuan untuk mengetahui model pembelajaran Auditory Intelletually Repetition (AIR) efektif dalam meningkatkan kemampuan pemahaman konsep matematis siswa.  Desain penelitian ini adalah Pre Experimental dengan bentuk penelitian yang digunakan adalah One Group Pretest-Posttest Design. Teknik pengambilan sampel yang digunakan adalah Simple Random Sampling. Setelah sampel diambil secara acak, terpilih kelas X IPA 2 sebagai kelas eksperimen. Instrument dalam penelitian ini berupa tes kemampuan pemahaman konsep matematis siswa. Teknik analisis data dalam penelitian ini menggunakan data N-Gain dan uji Paired Sample T Test (Uji t). Berdasarkan rata-rata nilai N-Gain dapat disimpulkan bahwa model pembelajaran Auditory Intelletually Repetition (AIR) efektif dalam meningkatkan kemampuan pemahaman konsep matematis siswa.

Abstract

This research is motivated by students experiencing difficulties in solving problems in the form of descriptions and students' problem solving abilities in learning mathematics are still low at SMP Negeri 7 Lubuk Basung in the 2020/2021 academic year, this is indicated by the lack of independence of students in learning mathematics. The purpose of this study was to determine whether there was a significant effect of learning independence on the mathematical problem solving abilities of eighth grade students of SMP Negeri 7 Lubuk Basung in the 2020/2021 academic year. The statistical analysis technique used in this research is regression analysis. The results of this study obtained a correlation coefficient value of rxy = 0.543 and a determinant coefficient value of KD = 29.4849% From hypothesis testing, for the significant effect of learning independence on mathematical problem solving abilities of class VIII students of SMP Negeri 7 Lubuk Basung obtained Zcount = 3.801 and Ztable = 1.96 at 0.05 confidence. The regression equation between learning independence and mathematical problem solving ability of eighth grade students of SMP Negeri 7 Lubuk Basung Y = -30.009 + 1.126X. If Zcount > Ztable, then the research hypothesis is accepted. This means that there is a significant effect of learning independence on students' mathematical problem solving abilities.Penelitian ini dilatarbelakangi oleh siswa mengalami kesulitan dalam menyelesaikan soal berbentuk uraian dan kemampuan pemecahan masalah siswa dalam pembelajaran matematika tergolong masih rendah di SMP Negeri 7 Lubuk Basung Tahun Pelajaran 2020/2021, hal ini diindikasikan oleh kurang mandirinya siswa dalam pembelajaran matematika. Tujuan dilaksanakan penelitian ini untuk mengetahui apakah terdapat pengaruh signifikan kemandirian belajar terhadap kemampuan pemecahan masalah matematika siswa kelas VIII SMP Negeri 7 Lubuk Basung Tahun Pelajaran 2020/2021. Teknik analisis statistik penelitian yang digunakan adalah analisis regresi. Hasil penelitian ini diperoleh nilai koefisien korelasi sebesar rxy = 0.543 dan nilai koefisien determinan sebesar KD = 29.4849% Dari pengujian hipotesis, untuk pengaruh signifikan kemandirian belajar terhadap kemampuan pemecahan masalah matematika siswa kelas VIII SMP Negeri 7 Lubuk Basung diperoleh Zhitung = 3.801 dan Ztabel = 1.96  pada kepercayaan 0.05. Persamaan regresi antara kemandirian belajar terhadap kemampuan pemecahan masalah matematika siswa kelas VIII SMP Negeri 7 Lubuk Basung Y = -30.009 + 1.126X. Jika Zhitung > Ztabel , maka hipotesis penelitian diterima. Artinya terdapat pengaruh yang signifikan kemandirian belajar terhadap kemampuan pemecahan masalah matematika siswa.

Abstract

The background in this study is based on the observations of researchers at SMA Negeri 1 Merangin, based on the data on the educational level of fathers of class XI MIPA students who are very diverse where the percentages for elementary school/equivalent are 7.79%, junior high school/equivalent 12.98%, high school/equivalent 56.49% and the tertiary level 22.72%. However, with the father's education level still elementary/equivalent and junior high/equivalent, this does not make the student's mathematics learning outcomes low either. This study aims to determine the difference in the level of father's education on the students' mathematics learning outcomes carried out at SMA Negeri 1 Merangin. This study is a population study using ex-post facto research methods. The total population in this study amounted to 154 students. Data collection techniques using documentation. Based on the results of the study using the Oneway Anova test, the significance value of students' mathematics learning outcomes was sig = 0.808, at a significance level of = 0.05. Because the value of sig = 0.808 > = 0.05 so H0 is accepted. It can be concluded that there is no difference in students' mathematics learning outcomes based on the father's education level in the elementary, middle and high categories in class XI MIPA at SMA Negeri 1 Merangin. Latar belakang pada penelitian ini didasari oleh hasil observasi peneliti di SMA Negeri 1 Merangin, berdasarkan data tingkat pendidikan ayah  siswa kelas XI MIPA sangat beragam dimana diperoleh pesentase untuk tingkat  SD/sederejat sebesar 7.79%, SMP/sederajat 12.98%, SMA/sederajat 56.49% dan tingkat perguruan tinggi 22.72%. Namun dengan masih adanya tingkat pendidikan ayah SD/sederajat dan SMP/sederajat, hal tersebut tidak menjadikan hasil belajar matematika  siswa tersebut rendah pula. Penelitian ini bertujuan untuk mengetahui perbedan tingkat pendidikan ayah terhadap hasil belajar matematika siswa yang dilaksanakan di SMA Negeri 1 Merangin. Penelitian ini adalah penelitian populasi yang menggunakan metode penelitian ex-post facto. Jumlah populasi pada penelitian ini berjumlah 154 siswa. Teknik  pengumpulan data menggunakan dokumentasi. Berdasarkan hasil penelitian menggunakan uji Oneway Anova diperoleh  nilai signifikansi hasil belajar matematika siswa sebesar sig = 0.808, pada taraf signifikansi α = 0.05. Karena nilai sig  = 0.808 >  α = 0.05 sehingga H0 diterima. Hal ini dapat disimpulkan bahwa tidak ada perbedaan hasil belajar matematika siswa berdasarkan tingkat pendidikan ayah kategori dasar menengah dan tinggi di kelas XI MIPA SMA Negeri 1 Merangin.
