Abstract

Students typically have less interest in learning mathematics because it is still seen as a challenging subject. As a result, when compared to other disciplines, the pupils' mathematics understanding abilities remained below average. The aim of this study was to find out how employing visual aids, such as PowerPoint, to teach geometric shapes to students improved their mathematical comprehension skills. This kind of study uses a random subject posttest design and is therefore quasi-experimental. The population of this study consisted of students in class VIII SMPN 1 Pagelaran; the samples were drawn using the purposive sampling technique from students in class VIII C, which was the experimental class, and class VIII D, which was the control class. The t-test, homogeneity test, and normalcy test are the data analysis methods employed. With a significant rate of0.05, the testing results for the hypothesis produced tstat= 3.2 > ttable= 1.6801. This indicates that while Ha is acceptable, Ho is denied. This demonstrates how employing PowerPoint-assisted visual aids in mathematics instruction increases students' capacity for mathematical knowledge.

Abstract

This study aims to analyze the effectiveness of mathematics learning with an open-ended approach in improving the learning independence of Vocational High School (SMK) students. This study uses a quasi-experimental method with a pretest-posttest control group design involving two groups of class XI Computer Network Engineering students (TKJ 1 and TKJ 2). The sample used was 72 students, which were divided into an experimental group and a control group. Data on student learning independence were collected through a learning independence questionnaire consisting of 36 statements that were analyzed using statistical tests with the help of the SPSS version 30 program. The results showed that the experimental group using an open-ended approach experienced a more significant increase in learning independence compared to the control group. This finding indicates that the open-ended approach is effective in improving student learning independence, which is very important in preparing them to face the dynamic world of work. However, the level of student learning independence is still in the low category, which indicates the need for the implementation of advanced strategies to further maximize the potential for student independent learning in the long term.
