Abstract

Tujuan dari penelitian ini adalah untuk mengetahui pengaruh model Pembelajaran Aptitude Treatment Interaction terhadap hasil belajar matematika siswa kelas VII SMP Negeri 20 Jakarta. metode penelitian yang digunakan dalam penelitian ini adalah metode quasi eksperiment, teknik pengambilan sampel menggunakan teknik Simple Random Sampling. Instrumen untuk mengumpulkan data pada penelitian berupa tes pilihan ganda. Pengujian persyaratan analisis data terdiri dari uji normalitas menggunakan uji Liliefors dan uji homogenitas menggunakan uji Fisher, diperoleh simpulan bahwa data berdistribusi normal dan homogen. Pada pengujian hipotesis dengan menggunakan uji-t, dan hasil uji-t menunjukkan bahwa pada taraf signifikasi 5% dan derajat kebebasan (dk=38) yang berarti , maka H0 ditolak dan H1 diterima. Sehingga dapat dikatakan rata-rata hasil belajar matematika siswa yang diajarkan mengggunkan model pembelajaran Aptitude Treatment Interaction lebih tinggi daripada rata-rata hasil belajar matematika siswa yang diajarkan menggunakan model pembelajaran konvensional. Dengan demikian, dapat disimpulkan bahwa terdapat pengaruh signifikan pada model pembelajaran Aptitude Treatment Interaction (ATI) terhadap hasil belajar matematika.

Abstract

The purpose from this research is to know self-efficacy influence toward student ability of mathematic problem solving. This research uses survey as the method. The population in this research consists of 181 students. This research is done by using questionnaires and tests with the total of the sample are 65 students. The sampling technique is done randomly and proportionally stratified (Proportionate Stratified Random Sampling). Data measurement and collection of student ability of mathematic problem solving use a written instrument like essay. Previously, the instrument was already tested in validity, reliability, difficulty level and distinguished tests ability so thereafter, data analysis requirement test is also conducted. Based on research hypothetical test, the result is t calculation > t table, which is 2,49 > 1,998 so H1 is accepted and H0 is rejected. The conclusion is there is an influence from self-efficacy towards toward student ability of mathematic problem solving.

Abstract

This study aims as a tool in learning to be more interesting, happy to be active and interactive between the teacher and students. In this development, the development model used is referring to the ADDIE (Analysis, Design, Development, Implementation, Evaluation) development model that is used to produce certain products and test the effectiveness of these products. The researcher concludes that the use of instructional media is very important in the teaching and learning process. Therefore, meaningful learning activities are needed so that students can master the concepts and properties of logarithms which are prerequisites for logarithmic functions. Ludo game is a type of game that is fun and entertaining to do, Ludo games can be played in groups that can increase interaction between students and their groups to support mutual cooperation and communicate well in order to finish the game. This research was developed to help students and teachers in learning mathematics using ludo media so that learning is more interesting.

Abstract

Kemampuan pemecahan masalah matematika merupakan salah satu tujuan pendidikan nasional di Indonesia, tetapi pencapaiannya masih tergolong rendah. Metode yang digunakan dalam penelitian ini adalah metode kuasi eksperimen dengan desain penelitian posstest-only. Pengambilan sampel pada penelitian ini menggunakan teknik purpose sampling. Sampel penelitian sebanyak 60 peserta didik yang terbagi dalam dua kelas (30 kelas eksperimen dan 30 kelas kontrol). Penelitian ini dilakukan di sekolah SMP N 10 Bekasi dan SMP N 26 Bekasi. Kelas eksperimen menggunakan model pembelajaran teamdengan strategi pembelajaran tugas dan paksa, sedangkan kelas kontrol menggunakan pembelajaran . Data yang terkumpul kemudian dianalisis dengan menggunakan uji beda rata-rata sampel bebas. Hasil analisis data menunjukan bahwa rata-rata nilai peserta didik yang pembelajarannya menggunakan model pembelajaran team assisted individualization dengan strategi tugas dan paksa lebih tinggi dibandingkan dengan rata-rata nilai peserta didik yang pembelajarannya menggunakan model pembelajaran langsung. Kata kunci: Model pembelajaran team assisted individualization, Strategi pembelajaran tugas dan paksa, kemampuan pemecahan masalah matematika ABSTRACT This research was conducted to determine the effect of team assisted individualization learning models with task learning strategies and forced to the ability to solve mathematical problems. Mathematical problem solving ability is an ability that belongs to the national education goals, but its achievement is still relatively low. The method used in this study is a quasi-experimental method with a poststest-only research design. Sampling in this study uses purpose sampling technique. The study sample consisted of 60 students divided into two classes (30 experimental classes and 30 control classes). This research was conducted in the school of SMP N 10 Bekasi and SMP N 26 Bekasi. The experimental class uses team individualization learning models with task and forced learning strategies, while the control class uses direct learning. The collected data is then analyzed using independent sample t-test. The results of data analysis showed that the average value of students who learned using the team assisted individualization learning model with higher task and forced strategies compared to the average value of students who learned using direct learning models. Keywords: Team assisted individualization learning model, task and forced learning strategies, mathematical problem solving skills

Abstract

This study aims to determine the effect of learning independence on mathematical problem solving abilities. The sample used in this study was 238 students with random sampling techniques from grade VIII students in the even semester at SMP Negeri 1 Depok and MTs Al Hidayah C.A Depok. The method used in this study is the survey method, data collection is carried out by distributing tests for variables of mathematical problem solving ability and questionnaires for variables of learning independence. Based on hypothesis testing and data analysis, it can be concluded that there is a significant positive influence between learning independence (X) and mathematical problem solving ability (Y). This is evidenced by Fcalculate > Ftable, which is 50.55 > 3.8812. With a determinant coefficient of learning independence on mathematical problem solving ability of 17.64% and 82.36%, the rest is influenced by other variables.

Abstract

This study aims to find out about the effect of mathematical anxiety on mathematical reasoning ability. The research method used for this research is quantitative survey research at SMKN 15 Bekasi City and SMK Global Teknologi for the 2021/2022 academic year. The sample used was 100 students consisting of class X with data collection techniques using simple random sampling. Data collection was carried out using questionnaire dissemination and question tests. This research was conducted in April - August 2022. The results revealed that based on the test obtained Fcalculate = 10.6107 and Ftabel = 3.94 with a significant level of ∝ = 0.05. Because Fcalculate > Ftable, H0 is rejected which means that there is an influence between mathematical anxiety and mathematical reasoning ability.
