Abstract

This research is motivated by the importance of quadrilateral material in mathematics lessons, especially for students as an educational subject in everyday life, while the aim is to analyze students’ mathematical creative thinking abilities in solving quadrilateral problems. This research is a qualitative descriptive study. The population in this study were all seventh-grade junior high school students in the city of Bandung whose sample was randomly selected at Paulus Middle School as many as 32 people. Students can be classified based on their creative thinking abilities based on (1) the Ability creative thinking of students with the high category is fulfilling 3 indicators of creative thinking namely fluency, flexibility, and novelty, so students with the high category is said to be creative. (2) Students' ability to think creatively with the medium category is fulfilling 2 indicators of creative thinking, namely fluency and flexibility, so students in the medium category are said to be not creative. (3) The creative thinking ability of students in the low category is fulfilling 1 indicators of creative thinking are fluency and students in the moderate category said students who are not creative. Data is obtained by testing creative thinking test questions as many as 4 questions that contain indicators. The results showed that there were 2 people with high ability, 4 people with moderate ability, and 26 people with low ability with various errors including conceptual errors, principal errors, and data operation errors. Based on this, it can be concluded that the creative thinking skills of junior high school students are still relatively low.

Abstract

The aim of the research is to develop teaching materials assisted by media construct 2 software that are practical and appropriate for use in the learning process. The research method used is Research and Development (R&D) using the ADDIE model. The research was conducted at SMPN 3 Rancabali  with 12 class VIII students at Rancabali 3 Middle School for limited trials and 9 students at SMPN 2 Rancabali and 9 students at SMPN 1 Rancabali Public for a wider trial and 27 VIII C class students as an experimental class and 27 class VIII A students as the control class for product trials. The validators consist of ICT experts, subject matter experts and teachers. The data collection technique was in the form of a response questionnaire from students and teachers. The research results of the products developed were in accordance with the ADDIE research method with product feasibility categories based on ICT expert validation of 81.25%, material experts 85% and teachers 88% are all included in the very decent category. Products that have been validated are then tested on students through limited trials, wider trials and product trials and students are given practicality questionnaires with a final average result of 83.56% included in the very practical category. Based on the validation results of ICT experts, material experts and student and teacher responses, it was concluded that the teaching materials assisted by the media construct 2 software are valid and appropriate for use in learning. For further research, the researcher hopes to be able to develop teaching materials better according to the suggestions from the respondents.

Abstract

Problem-solving skills are highly important in various aspects of life and professions, particularly in mathematics education. However, many students struggle to develop these skills due to a lack of understanding, critical thinking abilities, practice, and motivation. To address this, educators need to adopt teaching strategies that strengthen students' problem-solving skills. One effective approach is the scientific learning model, which emphasizes the scientific process, critical thinking, collaboration, and real-world applications. This study aims to assess the improvement of seventh-grade students' mathematical problem-solving skills using the scientific learning model. The research utilizes a descriptive quantitative approach with a two-group pretest-posttest design. The sample consists of seventh-grade students from an Islamic Junior High School, and data collection includes pretest and posttest questions. The N-gain formula is used to measure improvement. The findings indicate a significant improvement in problem-solving abilities among students who receive instruction using the scientific learning model compared to those who do not. The improvement is categorized as moderate in the experimental class, while the control class shows a lower level of improvement. Factors such as students' enthusiasm, implementation of real-life problems, and increased independence contribute to the improvement in students' problem-solving abilities. The implementation of the scientific learning model significantly enhances students' mathematical problem-solving skills. Based on the field findings, there is a need for improvement in soft skills to support meaningful learning activities.
