Abstract

This research is motivated by the lack of students' ability in understanding concepts so that it has an impact on students in learning mathematics. Because the ability to understand concepts is the basis of understanding principles and theories with the aim of making it easier for students to understand concepts in subsequent material in studying mathematics. One of the factors of the lack of students' ability to understand concepts is math anxiety which has a large influence on student learning processes, both at school and on the student's environment. This study aims to find out how students' conceptual understanding abilities are viewed from mathematics anxiety in the implementation of learning in class VII SMP Negeri 1 Mazo. This type of research is descriptive research with a qualitative approach. This research was conducted at Mazo 1 Public Middle School with a total of 35 research informants. Data collection techniques through written tests, student math anxiety questionnaires, interviews and documentation. Based on the results of the study, it shows that there are students who have the ability to understand mathematical concepts with high anxiety, moderate and low anxiety. Students with high anxiety still cannot solve the test questions in a structured way due to a lack of focus and feeling a little anxious. students who are anxious are students who are good at completing test questions coherently, it's just that there are some that are not done. Students who are low on anxiety, students are able to solve test questions that are given in a structured way because students are calm and don't feel anxious when facing math problems, it's just that they can't finish up to the final result, so that this can have an impact on student learning. So in this case the ability to understand concepts with math anxiety is that the higher the level of students' math anxiety, the lower the students' ability to understand mathematical concepts. Conversely, the lower the students' math anxiety level, the higher the students' understanding of mathematical concepts.

Abstract

This research is based on the results of observations and interviews with teachers at SMA Negeri 1 Ulu Idanotae where researchers obtained information that the ability to understand students' concepts was low, making it difficult for students to explain math problems, this is evidenced by the average student test scores. only around 59 with sufficient category. This study aims to find out how students' understanding abilities when using the Contextual Teaching and Learning model. This type of research is quantitative research with a descriptive approach. The research design used is the One-Shot Case Study. The research instrument used was a test of the ability to understand mathematical concepts. The number of population in this study is 215 people with a large sample of 36 people taken using nonprobability sampling with purposive sampling technique. Based on the results of the research, after learning in class using the Contextual Teaching and Learning learning model, it was obtained that the average ability to understand students' mathematical concepts was 75.38 which was in the good category. This is inversely proportional to the average ability to understand students' mathematical concepts when making initial observations, which were only around 59 in the sufficient category. It can be shown that the mathematical understanding ability of students at SMA Negeri 1 Ulu Idanotae increased when learning was implemented using the Contextual Teaching and Learning model.

Abstract

Matematika merupakan mata pelajaran yang penting dikuasai oleh siswa disekolah. Namun kenyataannya siswa SMP Negeri 2 Hiliduho masih megalami hambatan dalam memecahkan masalah matematis karena proses pembelajaran menggunakan model pembelajaran konvensional. Sehingga siswa tidak mampu menjawab pertanyaan yang diberikan oleh guru. Tujuan dari penelitian ini adalah mengetahui apakah ada pengaruh model pembelajaran Auditory Intellectually Repetition (AIR) terhadap kemampuan pemecahan masalah matematis siswa SMP Negeri 2 Hiliduho. Jenis penelitian ini adalah deskriptif kuantitatif. Model pembelajaran yang digunakan adalah model Auditory Intellectually Repetition (AIR).Tahap pertama pada model pembelajaran Auditory Intellectually Repetition (AIR) adalah Auditory berarti belajar dengan mendengar, tahap kedua yaitu Intellectually berarti menunjukkan apa yang siswa lakukan di pikiran mereka ketika mereka menggunakan kecerdasan untuk memikirkan pengalaman dan membuat koneksi, makna, rencana dan nilai dari pengalaman dan tahap ketiga yaitu Repetition adalah pengulangan yang berarti pendalaman, perluasan dan penguatan dengan cara mengajar siswa melalui tugas atau kuis. Selanjutnya, hasil penelitian ini diperoleh berdasarkan pengujian hipotesis, yaitu thitung = 11,30 dan ttabel = 1,68. Karena thitung = 11,30 > ttabel = 1,68, maka tolak Ho dan terima Ha, yang berarti: “Ada pengaruh model pembelajaran Auditory Intellectually Repetition (AIR) terhadap kemampuan pemecahan masalah matematis siswa”. Sehingga dapat disimpulkan bahwa model pembalajaran Auditory Intellectually Repetition (AIR) memiliki pengaruh terhadap kemampuan pemecahan masalah matematis siswa.

Abstract

Penelitian ini dilatar belakangi dari hasil pengamatan peneliti selama melaksanakan program magang di SMP Negeri 1 Gido dan ditemukan bahwa prestasi belajar matematika siswa masih dibawah KKM dan adanya perbedaan gaya belajar serta kurangnya motivasi belajar siswa. Tujuan dari penelitian ini adalah untuk menemukan dan mendeskripsikan hubungan antara gaya belajar dan motivasi belajar terhadap prestasi belajar matematika. Jenis penelitian ini adalah penelitian kuantitatif dengan metode korelasional. Instrumen penelitian yang digunakan adalah angket gaya belajar, angket motivasi belajar dan tes prestasi belajar matematika. Banyaknya populasi pada penelitian ini yaitu 292 dengan sampel yaitu 292 orang yang di ambil dengan menggunakan teknik sampling jenuh. Berdasarkan hasil penelitian diperoleh pada hipotesis pertama, nilai Zhitung (3,04) > Ztabel (1,96). Dengan demikian maka H0 ditolak dan H1 diterima, yang mana semakin tinggi tingkat gaya belajar siswa maka semakin tinggi prestasi belajar siswa begitu pun sebaliknya. Pada hipotesis kedua, nilai Zhitung (4,09) > Ztabel (1,96). Dengan demikian maka H0 ditolak dan H1 diterima, yang mana semakin tinggi tingkat motivasi belajar siswa maka semakin tinggi prestasi belajar siswa begitu pun sebaliknya. Pada hipotesis ketiga, nilai Zhitung (2,41) > Ztabel (1,96). Dengan demikian maka H0 ditolak dan H1 diterima, yang mana semakin tinggi tingkat gaya belajar siswa maka semakin tinggi motivasi belajar siswa begitu pun sebaliknya. Pada hipotesis keempat, nilai Fhitung (23,29) > Ftabel (3,02). Dengan demikian maka H0 ditolak dan H1 diterima dengan besar koefisien determinasi = 0,146. Kedua variabel bebas bersama-sama memiliki hubungan dengan variabel terikat dengan persentase 14,6%.
