Abstract

This research is motivated by the fact shows the mathematicalcommunication ability of the students not yet in accordance with theexpected. One such problem is learning that does not provide flexibility tostudents to exploit the potential of the brain optimally, where in general isgenerally more emphasis on the left brain function. Mathematicalcommunication skills need to be supported by right brain function.Characteristics of learning that offers learning concepts that align the waythe brain works naturally designed is by learning Brain-Based Learning(BBL). The research method used is quasi experiment. Quantitative data isobtained from pretest and posttes data. Research found that There areachievements and improvements in students' mathematical communicationskills whose learning uses the Brain-Based Learning approach comparedwith students who received conventional learning in terms of students' earlymath skills, and self-confidence and there is an association between theability of mathematical communication and self-confidence.

Abstract

Matematika terbentuk sebagai pemikiran manusia yang berhubungan dengan ide, proses, dan penalaran. Manusia hidup selalu berdampingan dengan masalah yang kompleks dan perlu adanya sikap kritis dalam menghadapinya dan mampu memprediksi suatu kejadian yang terjadi, serta mampu menyelesaikan masalah tersebut dengan penalarannya yang baik. Oleh karena itu, sangat diperlukan kemampuan literasi matematis pada diri setiap siswa. Selain kemampuan kognitif yang harus dikembangkan, tetapi juga kemampuan afektif harus dimiliki oleh setiap siswa.  Terdapat hubungan yang positif antara sikap dengan prestasi matematika, salah satunya dengan mathematical habits of mind. Tujuan penelitian ini untuk mendeskripsikan hubungan mathematical habits of mind terhadap kemampuan literasi matematis siswa SMP di Kabupaten Bandung Barat. Penelitian ini menggunakan pendekatan kuantitatif dengan analisis data korelasi. Penelitian ini dilakukan di SMP di Kabupaten Bandung Barat. Subjek pada penelitian ini sebanyak 37 siswa kelas IX yang dipilih dengan teknik purposive sampling. Hasil penelitian menunjukkan bahwa perolehan nilai korelasi -table sebesar , nilai -test -table sebesar , dan koefisien determinasi sebesar 39,8 %. Dapat diambil kesimpulan bahwa adanya hubungan yang signifikan antara mathematical habits of mind terhadap kemampuan literasi matematis siswa SMP di Kabupaten Bandung Barat, dengan pengaruh mathematical habits of mind terhadap kemampuan literasi matematis siswa sebesar 39,8 % dan sisanya dipengaruhi oleh faktor lain yang tidak diukur dalam penelitian ini. Memiliki mathematical habits of mind yang tinggi dalam diri siswa, akan memberikan peningkatan kemampuan literasi matematis yang baik.

Abstract

The problem raised in this research is that students' ability in making mathematical connections is still relatively low. This is because some of the theories in the learning of teachers still enjoy this way of learning, meaning that the students are only recipient of information without inspiration to active. Therefore, the authors are interested to conduct research by applying an NHT cooperative model setting to improve mathematical connection ability of junior high school students. This study aims to determine whether the knowledge of mathematical connections of junior high school students using learning methodology is better than junior high school students using ordinary learning. This research was conducted in SMP Krida Utama Padalarang Class VII, with research method the research used is quasi-experimental method. The sample of this research is taken two classes namely class VII A as experiment class and class VII B as control class. The research instrument is a set of mathematical connection test questions consisting of 5 test questions, and then tested by using a statistical test of differential. Based on the results of research and data processing, the authors conclude that the ability of mathematical connections of junior high school students whose learning using open-ended approach with learning model setting NHT type cooperative learning is better than the mathematical connection ability of junior high school students whose learning using ordinary learning.

Abstract

This research aims to develop learning tools of mathematics junior high school with a contextual approach as a tool for learning mathematics. The subjects are 34 students in the eighth grade of junior high school. The research method used is development research by referring to ADDIE development model which consists of five stages, namely analysis, design, development, implementation, and evaluation. The instruments are validation sheets of student worksheet, questionnaires, and test results. Results of this research are: (1) the validation result of student worksheet is in very good category; (2) the result of a questionnaire of student response is in very good category; and (3) the result of the student's learning test is in a good category. So that, student worksheet is feasible from the aspect of validity, practicality, and effectiveness.

Abstract

Untuk pencapaian berpikir kreatif matematis, diperlukan sebuah aspek penting yang harus dimiliki oleh siswa yaitu self confidence dan self efficacy yang baik, karena dalam self confidence dan self efficacy  terdapat indikator-indikator yang dapat mendukung tujuan tersebut. Penelitian ini bertujuan untuk mengetahui secara mendalam tentang terdapat pengaruh self confidence dan self efficacy secara simultan terhadap kemampuan berpikir kreatif matematis siswa SMP. Populasi dalam penelitian ini adalah siswa SMP di Kota Cimahi. Instrumen dalam penelitian ini berupa tes kemampuan berpikir kreatif matematis sebanyak enam soal, dan angket self confidence dan self efficacy siswa. Metode dalam penelitian ini menggunakan metode regresi ganda. Hasil penelitian ini menunjukan terdapat pengaruh self confidence dan self efficacy terhadap kemampuan berpikir kreatif matematis siswa SMP.
