Abstract

Penelitian ini bertujuan mengetahui peningkatan kemampuan pemecahan masalah siswa yang memperoleh  pembelajaran kooperatif tipe STAD lebih tinggi daripada kemampuan pemecahan masalah matematika siswa yang memperoleh pembelajaran secara langsung. Penelitian ini merupakan penelitian eksperimen semu (quasi experiment). Populasi dalam penelitian ini adalah seluruh siswa MTs Negeri di kabupaten Labuhanbatu yang berakreditasi A dan B. Sampel penelitian ini adalah MTs Negeri 1 Labuhanbatu dan MTs Negeri 2 berjumlah117 siswa. Validitas instrument angket dilakukan dengan analisis butir menggunakan rumus korelasi Product Moment dan uji reliabilitas menggunakan rumus Alpha Cronbach. Teknik analisis data menggunakan uji normalitas dengan uji Chi Kuadrat dan untuk menghitung peningkatan kemampuan pemecahan masalah  matematika setelah pembelajaran dengan pembelajaran kooperatif tipe STAD dan pembelajaran langsung, maka digunakan uji gain ternormalisasi (g). Siswa yang mendapat model pembelajaran kooperatif tipe STAD memperoleh rata-rata peningkatan kemampuan pemecahan masalah matematis sebesar 0,63 dan siswa yang mendapat model pembelajaran langsung dengan rata-rata peningkatan kemampuan pemecahan masalah matematis sebesar 0,36. Berdasarkan hasil analisis data penelitian diperoleh hasil bahwa ada peningkatan kemampuan pemecahan masalah siswa yang mengikuti pembelajaran koopertiftipe STAD lebih tinggi dari pada siswa yang mengikuti pembelajaran langsung.This study aims to determine the increase in the problem-solving ability of students who get cooperative learning type STAD is higher than the mathematical problem solving abilities of students who receive direct learning.This research is a quasi experiment research. The population in this study were all State MTs students in Labuhanbatu district who were accredited A andB. The sample of this research is MTs Negeri 1 Labuhanbatu and MTs Negeri 2 totaling 117 students.The validity of the questionnaire instrument was carried out by analyzing items using the Product Moment correlation formula and reliability testing using the Cronbach Alpha formula. The data analysis technique used the normality test with the Chi Squared test and to calculate the increase in mathematical problem solving skills after learning with STAD cooperative learning and direct learning, the normalized gain test (g) was used. Students who received the STAD cooperative learning model obtained an average increase in mathematical problem solving abilities of 0.63 and students who received a direct learning model with an average increase in mathematical problem solving abilities of 0.36. Based on the results of the research data analysis, it was found that there was an increase in the problem solving ability of students who took STAD type coopertive learning higher than students who took direct learning.

Abstract

A geometric shape or also called a geometric shape is a three-dimensional shape that has space and is limited by sides. Spatial structure is a characteristic of concrete objects that we often encounter every day. Rapid technological advances in the world of information technology and computers also have an impact on the world of education, which offers various conveniences and innovations. Augmented Reality or often abbreviated as AR is a technology that is able to combine real and virtual situations at one time which is displayed in real time. With AR technology, it is hoped that it can provide innovation and new learning experiences in recognizing and studying spatial shapes, so that it can attract the interest of students who are studying it.

Abstract

The development of communication and collaboration skills constitutes a critical demand in 21st-century learning. However, classroom practices remain predominantly teacher-centered, limiting students’ opportunities to actively engage in scientific investigation and collaborative work. This study aims to examine the effectiveness of the Investigation-Based Scientific Collaborative (IBSC) learning model in enhancing students’ communication and collaboration skills.This research employed a quasi-experimental design involving students as research participants. The experimental group received instruction using the IBSC model, while the control group was taught using conventional methods. Data were collected through assessment instruments measuring communication and collaboration skills, observation sheets, and supporting documentation. Data analysis was conducted using descriptive and inferential statistics to determine differences between the two groups.The findings indicate that students taught using the IBSC model demonstrate significantly higher communication and collaboration skills compared to those taught through conventional learning. The IBSC model promotes active student engagement in investigative activities, scientific discussions, and collaborative problem-solving, thereby positively influencing their ability to communicate and work effectively in teams.This study concludes that the Investigation-Based Scientific Collaborative (IBSC) learning model is effective as an alternative instructional approach for developing students’ communication and collaboration skills.
