Abstract

This research is motivated by the results of observations found in the pandemic era, namely that there are still many educators who have difficulty in carrying out the teaching and learning process, which is caused by the limited face-to-face learning process where some learning is done online, thus making educators have to be careful in choosing learning models. to increase students' willingness to learn. This study aims to examine whether the learning outcomes of students who are taught using the Blended Learning model are higher than the learning outcomes of students who are taught using direct learning on algebraic forms of material. This research is in the form of an experiment with a quasi-experimental type and the design used in this study is the Posttest Only Control Group Design. The sample is part of the population. The sample of this study was taken 2 classes randomly, namely class VII B as the experimental class applied the Blended Learning model and class VII A as the control class using direct learning. The results of the study were analyzed using a t-test with a significance level of 0.05 is indicated by the calculated 7.191967906 > Ttable=2.009575237 so that H0 is rejected and H1 is accepted.

Abstract

This study aims to describe the mistakes of class VII students of SMP Negeri 1 Tondano in solving questions on the Algebraic Forms material in the bold and alluring learning process. The errors referred to here may occur in solving Algebra Form problems, including principle and concept errors. The type of research used is descriptive research with a qualitative approach. Data collection techniques are carried out through tests, interviews, and documentation. The sources and subjects of this study were class VII students of SMP Negeri 1 Tondano T/A 2020/2021 and T/A 2022/2023, who were selected based on considerations. Data analysis techniques in this study are the stages of data reduction, data presentation, and conclusions. The results of this study indicate that the mistakes made by students are: 1) conceptual errors, where they cannot identify elements in the algebraic form, such as terms, variables, coefficients, and constants. 2) the principle of error, where it is wrong to operate algebraic forms that have negative terms, and errors in determining operations on terms that are not similar. The causal factors in brave learning are: 1) working on questions in a hurry; 2) do not understand the concept in Algebraic Forms; 3) do not know how to operate tribes that are not of the same type; 4) do not know the correct settlement calculation operating procedure; 5) not careful in working on the questions; 6) ambient distractions that make it out of focus. The causal factors in engaging learning are: 1) Class conditions are not conducive; 2) decreased student discipline.

Abstract

Students' information gathering is heavily reliant on their learning styles. Mathematical education calls for a deeper examination of methodological variations. This study examines the correlation between students' learning styles and their ability to solve math word problems involving a system of two-variable linear equations. The method employed is a qualitative, descriptive research method. The instruments utilized are student aptitude and learning style assessments. Data analysis methods include data collection, data reduction, and data interpretation. The findings included that the visual and auditory subjects completed only three of the five questions they deemed simple. Comparatively, kinesthetic subjects were able to answer four questions. When reexamining the visual, auditory, and kinesthetic subjects, the obtained answers are not rechecked. By concluding the solution process, visual and kinesthetic subjects exhibit similarities. In the final phase, the auditory subject neither concludes nor responds to the initial questions.

Abstract

Dalam penelitian ini siswa kelas VIII SMP Negeri 1 Modayag Barat dipaparkan pada materi SPDV dengan menggunakan model pembelajaran kooperatif terhadap TAI. Kedua kelompok dalam penelitian ini menggunakan desain kelompok kontrol non-ekuivalen yang dipilih tanpa menggunakan seleksi acak. Untuk mengetahui kondisi baseline dan tingkat pemahaman materi SPLDV serta baseline kemampuan matematika, dilakukan pretest pada kedua kelompok. Siswa kelas VIII A dan VIII B menjadi sampel penelitian sebanyak 40 siswa. Tes adalah instrumen yang digunakan. Statistik deskriptif dan statistik inferensial digunakan dalam proses analisis data. Berdasarkan hasil penelitian, rata-rata hasil belajar siswa pada pretest kelas eksperimen sebesar 34, sedangkan pada kelas kontrol sebesar 32,9. Pada kelas eksperimen rata-rata hasil belajar setelah menggunakan model pembelajaran kooperatif tipe TAI sebesar 82,3, sedangkan pada kelas kontrol rata-rata hasil belajar setelah diterapkan model pembelajaran ekspositori sebesar 75,1. H0 Ditolak dapat disimpulkan dari temuan analisis inferensial bahwa thitung > ttabel (2,4 > 1,70). Akibatnya terdapat kesenjangan antara hasil belajar matematika materi SPLDV siswa yang memperoleh pembelajaran menggunakan model pembelajaran kooperatif terhadap TAI dengan yang memperoleh pembelajaran menggunakan pendekatan pembelajaran ekspositori. Studi ini menunjukkan bagaimana teknik pembelajaran kooperatif seperti TAI dapat meningkatkan kinerja akademik siswa secara signifikan.
