Abstract

Kemampuan siswa untuk menganalisis, menalar, serta merumuskan, memecahkan, dan menginterpretasikan masalah matematika dalam berbagai bentuk dan konteks merupakan inti keterampilan matematika. didalam  mengajarkan matematika di Sekolah Menengah Pertama hal yang tidak mudah, bahkan rintangannya sangat banyak sekali dan kendala yang dialami oleh para pendidik. terkhusus pembelajaran yang dapat mendukung keterampilan numerasi, dan memiliki manfaat secara kontekstual dalam memecahkan masalah didalam kehidupan. untuk mengevaluasi dampak dari model pembelajaran berbasis masalah akan kecakapan matematika dan numerik siswa kelas VII di SMP Muhammadiyah 51 Sidikalang merupakan tujuan dari penelitian ini. Penelitian ini memakai metode eksperimen semu serta metode survei kuantitatif dan desain pre-test dan post-test group. dengan mengikutsertakan statistik deskriptif dan statistik analisis inferensial merupakan bagian dari analisis dalam penelitian ini. analisis data awal memakai statistik deskriptif menunjukkan bahwa sebelum diterapkannya model pembelajaran berbasis masalah di SMP Swasta Muhammadiyah 51 Sidikalang, kinerja siswa dalam kategori rendah sebesar 24% dan kategori sedang atau tercapai sebesar 76%. Namun, setelah penerapan model pembelajaran berbasis masalah, terjadi peningkatan signifikan dalam kinerja siswa. Proporsi siswa dalam kategori sedang meningkat sebesar 20%, sementara proporsi siswa dalam kategori tinggi meningkat sebesar 80%. hasil dari analisis statistik inferensial menggunakan paired sample T-test terlihat kalau nilai signifikansi lebih besar dari 0,05. Hal ini mengindikasikan jika penerapan model pembelajaran berbasis masalah berdampak positif terhadap kemampuan matematika dan numerik siswa setelah dilakukan pengujian statistik. Dengan demikian, dapat ditarik kesimpulkan kalau pengaruh model pembelajaran berbasis masalah di SMP Swasta Muhammadiyah 51 Sidikalang Kelas VII memiliki dampak yang positif terhadap keterampilan matematika dan numerik siswa.

Abstract

This study aims to determine how the effect of the Problem Based Learning (PBL) model on students' mathematical problem solving abilities in the Comparison material for class VII Private Junior High School PAB 1 Klumpang in the 2020/2021 academic year. The instrument used in this research is a mathematical problem solving ability test in the form of a description, with the material being taught is a comparison. The subjects in this study were seventh grade students of PAB 1 Klumpang Private Junior High School, while the sample in this study consisted of two classes. One class is the experimental class and the other is the control class. The sample in the experimental class amounted to 30 people, and the sample in the control class also amounted to 30 people. From the data analysis using simple regression test, the average test of mathematical problem solving ability in the experimental class before and after learning was 73.33 and 83.83. While the average control class math problem solving ability test before and after learning was 74.17 and 75.5. Hypothesis testing in this study used the r-test, which was conducted to determine the level of students' mathematical problem solving abilities before and after being taught using the Problem Based Learning (PBL) learning model. If > then it can be concluded that there is an effect of Problem Based Learning (PBL) learning model on students' mathematical problem solving abilities. After the calculation, the score on the mathematical problem solving ability of experimental class students is 0.722 while the value is 0.361, so it can be seen that > . Thus, it can be concluded that there is an effect of the Problem Based Learning (PBL) learning model on students' mathematical problem solving abilities in the Comparison material for class VII Private Junior High School PAB 1 Klumpang in the 2020/2021 academic year.

Abstract

The traditional otok-otok game as a STEAM (Science, Technology, Engineering, Art, and Mathematics) based project can be used for mathematics learning. Research like this has never been done. The aim of this research is to describe students' collaborative skills through the Ethno-STEAM Project learning approach. The research subjects were 32 students with a pre-experimental research type with a one-shot case study design. Data regarding students' collaborative skills was obtained from student self-report questionnaires and data was strengthened through collaborative activity observation sheet forms. Data analysis uses descriptive statistics in the form of total scores and average percentages for each aspect or subdomain. The application of Ethno-STEAM Project learning in the context of otok-otok games produced results, namely that students' collaborative skills were in the high category 56%, in the medium category 31%, and in the low category 13%. Aspects of collaborative skills in the high category include motivation, contribution, problem-solving, time management, group dynamics, and interaction with group members. Aspects that need further development are in the categories of work quality, group support, readiness, roles, and reflection. The application of the Ethno-STEAM approach to the otok-otok game project in mathematics learning can be an alternative for developing students' collaborative skills

Abstract

One aspect that plays an important role in life is education, especially in learning mathematics, where students first avoid it and think that mathematics is difficult, so this makes students' interest in learning decrease. The aim of this research is to find out the influence of giving rewards and punishment on students' interest in learning in mathematics subjects. The research method used in this research uses a quantitative approach with the instrument used, namely SPSS 25 for Windows, while the data collection technique uses a questionnaire and data analysis uses the classic assumption test. The research results show that 1) Rewards and punishments simultaneously influence students' interest in learning by 92 percent; 2) Compensation influences interest rates significantly, as shown by the sign value of 0.003 being less than 0.05; and 3) Compensation significantly influences students' interest in learning, as shown by the mark value of 0.002 which is less than 0.05. The punishment variable is the most influential in terms of its significance value. It can be concluded that the rewards and punishments given by teachers or educators to students influence their interest in learning mathematics subjects.

Abstract

This research aims to improve the learning outcomes of class 1 students at SD Negeri 060912 Medan by implementing the Problem Based Learning learning model with puzzle media. This type of research is Classroom Action Research (PTK) which is carried out in 2 cycles. Before entering cycle I, students are given a pre-cycle test first to determine the students' abilities. After carrying out the pre-cycle test, learning activities enter cycle I stage then proceed to cycle II stage. The subjects of this research were 1st grade students at SD Negeri 060912 Medan, totaling 21 students. The results of this research show that the learning outcomes of students using the Problem Based Learning model using puzzle media showed an increase in the learning outcomes of students who achieved completeness by 57.1%, then in cycle II students who achieved completeness also experienced an increase of 90.5%. From these results it can be concluded that from cycle I to cycle II there was an increase in completion by 33.4%. This shows that the application of the Problem Based Learning learning model using puzzle media can greatly improve students' results.
