Abstract

This Research aims toanalyze the influece of the learning environment on the mathematics learning achievent of class VIIIA students at Karuni Christian Middle School. The learning environment in question includes physical, social, psychological aspects, as well as the learning methods applied. The research medhod used is a quantitative approach with data collection techniques through quesrionnaires and documentationnof students’ UAS scores. The research sample consisted of 27 students, research time was the even semester of the 2024/2025 academic year. Data analysis was carried out using descriptive statstics, simple linear regression tests, and pearson correlation tests eith the help of the SPSS aplication. Thr resarch results show that students’ perceptions of the learning environment are classified as good with an average score of 4.29 (scale 1-5). The average student mathematics achievement score was 74.69. the pirso correlation test shows that there is a positive and significant relationship between the learning environment anf mathematics learning schievement with a correlation coefficient (r)= 0.65 and significant (p)= 0.001. This means that the higher the mathematics learning achievement achievend.

Abstract

This study aims to identify the types of errors made by students in solving quadratic equations and analyze the factors that cause them. The research method used is descriptive qualitative with data collection techniques through written tests, interviews, and documentation. The research subjects consisted of 11 students in class IXB of SMP Negeri 1 Loura with instruments in the form of test questions and interview guidelines. The results of the study show that reading errors accounted for 45.45%, characterized by inaccuracies in making assumptions. Errors in understanding the questions also accounted for 45.45%, because students did not write down the known and asked information completely. Question transformation errors reached 81.81%, where students were inaccurate in writing down the mathematical model or did not write it down at all. Process skill errors also accounted for 81.81%, characterized by incorrect calculations and incomplete work. At the stage of writing the final answer, all students (100%) did not write the conclusion or answer correctly. These findings indicate that the dominant errors were in question transformation, process skills, and writing the final answer. The main factors causing these errors were a lack of conceptual understanding, lack of focus, and low accuracy among students. Therefore, a learning strategy that emphasizes understanding the concept of quadratic equations and accustoming students to writing down the steps to solve the problem in sequence is needed.

Abstract

This study aims to determine the effect of Kahoot-based Game Based Learning on the learning interest of seventh-grade students at SMP Negeri 1 Waikabubak in mathematics. The study used a quasi-experimental method with a pretest-posttest control group design. The study population consisted of all seventh-grade students at SMP Negeri 1 Waikabubak in the 2024/2025 academic year. The sample was selected using purposive sampling and consisted of two classes. Data were collected through a multiple-choice test consisting of 10 questions and a learning interest questionnaire containing 15 statements. The results showed that the use of Kahoot had a significant effect on students' learning interest. The significance value of the hypothesis test was 0.000 < 0.05, so H0 was rejected and Ha was accepted. The comparison of average scores also reinforces these results, with the control class mean of 49.42, while the experimental class reached 63.12. N-Gain analysis shows that the increase in learning interest in the control class was in the moderate category with an average of 0.52, while in the experimental class it was in the high category with an average of 0.80. Thus, it can be concluded that the application of Kahoot-based Game Based Learning can significantly increase student learning interest compared to conventional learning. These findings confirm that the integration of technology-based interactive learning media can be an effective strategy in increasing student engagement, especially in learning mathematics on algebraic operations in junior high school

Abstract

This study aims to analyze students' errors in solving Pythagorean theorem problems using the Problem Based Learning (PBL) learning approach. The method used is a qualitative method with a descriptive approach aimed at determining the types of errors in solving Pythagorean Theorem problems after PBL. The results of the study showed that students' errors varied, ranging from conceptual errors such as understanding the definition of the Pythagorean theorem to procedural errors such as errors in calculations and use of formulas. These errors are influenced by students' understanding of basic concepts, problem-solving skills, and students' ability to apply the Pythagorean theorem in various problem contexts. The results of the study showed that students' abilities in solving Pythagorean Theorem problems that answered the questions correctly were still lacking. The cause of the errors made by students was that students were not careful in reading the questions, were not careful in understanding the questions so that they made mistakes in writing what was known and what was asked, so that they were less able to solve the questions so that they made mistakes in solving the questions.

Abstract

The cause of the problem of low learning outcomes for fourth grade students at Pogo Lede State Elementary School in mathematics subjects consists of teacher and student foctors. Teachers are less creative in delivering material, do not use media that, can attract students’ attention and interest in learning, focus more on using prinred books, and do not involve students. Apart from that, he also has difficulty in calculating. This makes students feel bored, fed up and sometimes students just sit still during the learning process so that the material provided by the teacher cannot be received optimally, causing the learning outcomes of class IV students at SD Negeri Pogo Ledeto still be below average. This research uses classroom action research (PTK) techniques because the research is carried out to solve problems that occur in the claasroom. In classroom action research improvements are carried out gradually and continuously as long as the research activities are carried out. Therefore, in PTK there is an implementation cycle in the from of a planning pattern. Carrying out observations and reflections so that in the next dycle it reaches the level you want to achieve. Based on the background above, the researcher chose to apply the puzzle game learning method. This method can make students activel discuss in class or in small groups to formulate the title improving learning outcomes using puzzle game tools on operation material counting mixed integers class IV Pogo Lede State Elementary School
