Abstract

This study aims to analyze the students' difficulties in solving problems on the flat side of the space. The method used in this study is a qualitative descriptive method with the population used is 26 junior high school students in one of the schools in Cianjur Regency. The data collection technique carried out in this qualitative descriptive study was carried out by giving a description test question of 5 questions. The data analysis technique used is data reduction, data presentation and concluding research results. The conclusion of the data is taken from the percentage of the question indicators and then concludes the average results of the overall indicators. The result of this research is that students are still wrong in solving flat-sided space problems, precisely on questions number 4 and 5, with the indicator for question no 4 is determining the volume of cubes and blocks and question number 5 with indicators determining the surface area of the pyramid. The difficulty of students in solving questions number 4 and 5 is that students do not understand the problems contained in the questions so that students are wrong about taking steps in solving problems. In addition, students' errors in solving flat-sided geometrical problems are (1) negligence in analyzing the problem; (2) Lack of students' accuracy in answering questions; (3) It is difficult to determine how to answer the question.

Abstract

Everything will function more smoothly and successfully with the aid of career planning, which enables people to recognize and formulate actionable actions toward achieving their professional objectives. The purpose of this study was to determine how the traditional guidance services combined live modeling methods on career planning for eighth-grade students at SMPN 5 Cimahi The study employed quantitative research approaches and had sample 76 students in total, with 38 students in each session. The experimental and control groups were established use a quasi-experimental non-equivalent control group design technique. A career planning survey tool was employed, and a portion of the information was derived from the 1958 theory of John Milton Dillard. The researcher was assigned to the effective group after achieving an average n-gain test score of 90.7% in the experimental class. By contrast, the average n-gain test result for the control class was 54.1%, putting it in the less effective group. Students in the eighth grade at SMPN 5 Cimahi believe that career preparation is greatly benefited by traditional mentoring via direct modeling approaches.

Abstract

This research examines the impact of the Problem-Based Learning (PBL) model on students' mathematical problem-solving proficiency in the context of integers. Adopting a quasi-experimental design, 54 seventh-grade students were assigned to either an experimental or control group. Statistical analysis—including normality, homogeneity, N-gain, and independent t-tests—indicated that the experimental group significantly outperformed the control group (N-gain of 0.84 vs. 0.54; p < 0.05). These findings suggest that implementing the PBL model provides a more effective pedagogical alternative to conventional methods for improving students' mathematical problem-solving skills.

Abstract

This study aims to comprehensively analyze and describe the mathematical concept understanding ability of junior high school students on the topic of sets. The novelty of this research lies in the in-depth analysis of misconceptions for each indicator across all student ability levels. The method used is descriptive qualitative, involving a sample of 25 seventh-grade students at a private junior high school in Cimahi City. Data were collected through a test instrument consisting of three essay questions representing each indicator. The results showed that: (1) Students with a high ability level (16%) successfully mastered all indicators, although there were still minor inaccuracies in the classifying indicator; (2) Students with a medium ability level (76%) were only able to fulfill the restating indicator, but failed to provide logical reasoning for classifying and had not achieved the target for categorizing; (3) Students with a low ability level (8%) failed to meet the criteria across all indicators, indicating fundamental misconceptions in solving set problems. In conclusion, the mathematical understanding of the majority of students falls into the medium category, which is influenced by their lack of enthusiasm for learning.
