Abstract

The learning problem experienced by students is a lack of concentration when the teacher explains the material. Teachers still do not involve students in the teaching and learning process activities. The purpose of this research is to determine the differences in student learning outcomes taught with the STAD model and the Direct Instruction (DI) model on comparative material. This survey was conducted at SMPN 8 Bitung in the 2022/2023 academic year. The type of research used is quantitative with a posttest only control group design. The sample selection was chosen through pretest results from the three classes. Based on the pretest scores, the same and homogeneous classes were classes VII A and VII B. Through drawing lots, class VII A was the control class and VII B was the experimental class. The data collection technique is a test at the end of the meeting. Learning outcomes are obtained from student learning outcome data obtained from the final exam (posttest) in the form of a test. Research statistics were analyzed using a test of two means (t test) which showed that tcount=1.991 > ttable=1.677 with H0 rejected in the difference of two means test (t-test) at the real level α = 0.05. This shows that the average learning outcomes of students taught using the STAD type cooperative learning model are higher than the average learning outcomes of students taught using the DI model in comparative material.

Abstract

Matematika memiliki peran penting dalam berbagai disiplin ilmu. Namun, banyak siswa menganggap matematika sebagai pelajaran yang sulit, sehingga minat mereka dalam mempelajarinya menurun. Salah satu penyebabnya adalah metode pembelajaran di kelas yang masih sering menggunakan model ceramah, yang membuat siswa kesulitan memahami materi yang disampaikan. Tujuan dari penelitian ini adalah untuk menghasilkan Lembar Kerja Peserta Didik (LKPD) berbasis model pembelajaran Search Solve Create Share (SSCS). Teknik pengumpuan data yakni observasi dan wawancara. Penelitian ini merupakan penelitian pengembangan yang menggunakan model ADDIE dengan tiga tahapan (analysis, design, dan development). Data validasi menunjukkan bahwa bahan ajar mencapai presentase 83,75% dikategorikan layak, berdasarkan penilaian dosen pendidikan matematika, dan 93,33% dikategorikan sangat layak berdasarkan penilaian guru matematika. Hasil survey tanggapan siswa menunjukkan kategori sangat layak dengan presentase 87,40%. Implikasi dari hasil penelitian adalah untuk meningkatkan pengetahuan dan pemahaman siswa lewat model pembelajaran yang inovatif.

Abstract

This study aimed to determine the differences in student learning outcomes between the application of the Guided Discovery Method with the Constructivism Learning Model and Conventional Learning in improving students' understanding of integers in Class VII at SMP Negeri 3 Tondano. This research was a quasi-experimental study with a two-group pretest-posttest design. The population of this study was seventh-grade students, and the samples in this study were VII A as the experimental class, consisting of 25 students, and VII B as the control class, consisting of 22 students, at SMP Negeri 3 Tondano in the 2024/2025 academic year. The research results revealed that there was a significant difference in the average learning outcomes of students taught using the Guided Discovery Method with the Constructivism Learning Model compared to students taught using Conventional Methods. Based on the above results, it is concluded that the application of the Guided Discovery Method with the Constructivism Learning Model can improve students' understanding of integers in Class VII at SMP Negeri 3 Tondano. Thus, the Guided Discovery Method with the Constructivism Learning Model was proven effective in improving students' learning outcomes.

Abstract

In the paper [1], it was given a function which belongs to the bounded Stummel modulus classes but not in Stummel classes. The given proof of this function properties in that paper was not obvious and very concise. By using the countable linearity property of integral, polar coordinate of integration, other properties of Lebesgue measure and integration, and some observation on the geometric property of the open ball in Euclidean spaces, we prove in detail the properties of this function.

Abstract

Let n-2<\lambda<n , f be a function in Morrey spaces L^{1,\lambda}(\Omega) , and the equation Lu=f u \in W^{1,2}(\Omega) be a Dirichlet problem, where \Omega is a bounded open subset of R^{n} , n \ge 3 , L and is a divergent elliptic operator. In this paper, we prove the existence and uniqueness of this Dirichlet problem by directly using the Lax-Milgram Lemma and the weighted estimation in Morrey spaces

Abstract

This article aims to determine the effect of using the project-based learning model with the peer tutoring method in teaching Archimedes' principle in physics. This research was conducted at SMA Negeri 1 Tombatu using a quantitative research design with a one-group pre-test post-test design. The use of the project-based learning model with the peer tutoring method enabled students to understand the material taught, based on student learning outcomes, namely the pre-test results showed that the average score of students was 35.83 and increased to 84 in the post-test results. Thus, it can be concluded that the use of the project-based learning model with the peer tutoring method has a significant effect on student learning outcomes in physics learning on Archimedes' principle.
