Abstract

Penelitian ini bertujuan untuk melihat kesulitan-kesulitan yang dialami oleh guru matematika selama penerapan pembelajaran jarak jauh pada Masa Covid-19 di MAN 1 Medan. Penelitian ini menggunakan jenis penelitian kualitatif, dengan metode pengumpulan data yang didapatkan dari hasil wawancara dengan subjek penelitian, observasi dan juga dokumentasi. Di dapatkan hasil penelitian bahwa guru matematika merasa kesulitan untuk menerapkan pembelajaran jarak jauh. Seperti, jaringan internet yang tidak stabil, kesulitan untuk memberikan penilaian kepada siswa, serta kesulitan dalam membuat media pembelajaran jarak jauh. Kesulitan yang dialami guru tersebut disebabkan oleh faktor yaitu ketersediaan serta kemampuan jaringan yang kurang memadai, dan sarana yang digunakan untuk membuat media pembelajaran kurang muncukupi. Serta solusi yang dilakukan oleh guru untuk mengatasi kesulitan yang terjadi selama menerapkan pembelajaran jarak jauh dengan membolehkan bagi siswa yang ingin belajar dan memahami secara langsung materi matematika yang sulit dimengerti dengan guru matematika, dan sekolah menyediakan fasilitas wifi bagi guru, dan kuota internet gratis bagi siswa. Kata Kunci: : Pembelajaran Jarak Jauh, Kesulitan, Guru Matematika. ABSTRACT This study aims to look at the difficulties experienced by math teachers during the implementation of distance learning during the Covid-19 Period at MAN 1 Medan. This research uses a type of qualitative research, with data collection methods obtained from interviews with research subjects, observations and documentation. In the results of research that math teachers find it difficult to apply distance learning. Such as, unstable internet networks, difficulty to provide assessments to students, as well as difficulties in making distance learning media. The difficulties experienced by teachers are caused by factors, namely the availability and ability of inadequate networks, and the means used to make learning media less fulfilling. As well as solutions carried out by teachers to overcome the difficulties that occur during implementing distance learning by allowing for students who want to learn and understand directly math materials that are difficult to understand with math teachers, and schools provide wifi facilities for teachers, and free internet quotas for students. Keywords : Distance Learning, Difficulties, Math Teacher.

Abstract

This research was carried out with the aim of finding out the effect of the Argument-Driven Inquiry Learning Model on students' mathematical thinking abilities at TNAS KARYA Batang Kuis Middle School for the 2023/2024 academic year. This research method is quantitative and the type of research is Quasi Experimental with the research design being Pretest-Posttest-Only Control Design. The data analysis technique in this research uses analysis prerequisite tests, namely: 1) Normality test, the results of the normality test produce a sig value. from the Pretest and Posttest data for the experimental and control classes is greater than 0.05, so the data is normally distributed, 2) Homogeneity test, the results of the homogeneity test for the Posttest data for the experimental class and control class are 0.479 and the sig. is greater than 0.05, then the variance of the two groups is homogeneous. 3) Hypothesis testing using the t test, the results of the t test show that the significant value (2 tailed) = 0.001 < 0.05. The significant value of the data is smaller than 0.05, so H0 is rejected. So it can be concluded that there is an influence of the Argument-Driven Inquiry learning model on students' mathematical critical thinking abilities.

Abstract

The development of appropriate learning materials is essential to support active learning and to enhance students’ understanding of mathematical concepts, particularly in problem-solving activities that require logical and systematic thinking. This study aimed to develop Student Worksheets (LKPD) on integer topics that meet the criteria of validity, practicality, and effectivity in improving seventh-grade Students’ Mathematical Problem-Solving Abilities at SMP Negeri 3 Halongonan. This research applied a Research and Development (R&D) method based on the 4D development model, which includes the stages of define, design, develop, and disseminate. The participants of this study were seventh-grade students at SMP Negeri 3 Halongonan. The instruments used in this study consisted of validation sheets assessed by media and subject-matter experts, student response questionnaires, and a test measuring mathematical problem-solving skills. The results indicated that the developed worksheets achieved a validity score of 87.27% from media experts, categorized as highly valid, and 75% from subject-matter experts, categorized as valid. The practicality test showed a percentage of 67.26%, indicating that the worksheets were practical and easy to implement in classroom learning activities. The effectiveness of the worksheets was indicated by an increase in students’ mathematical problem-solving skills, as reflected by an N-gain value of 0.55, classified as category. These findings suggest that the developed worksheets help students better understand integer concepts, increase learning engagement, and support the development of mathematical reasoning skills. Therefore, the developed LKPD is considered appropriate and practical to implement as a mathematics teaching medium for integer topics for seventh-grade students at SMP Negeri 3 Halongonan.
