2025-01-22T08:10:18+00:00

This research is a classroom action research (PTK), this research was conducted to improve the learning outcomes of students through the use of time unit cards in mathematics subjects for students in class 2C SD Negeri Pandeglang 4. The purpose of this research is to find out 1) The use of time unit cards in the mathematics subject of grade 2 SD Negeri Pandeglang 4, and 2) Improvement of learning outcomes in mathematics through the use of time unit cards. The subjects of this study were class 2C students in the 2022/2023 academic year totalling 30 students consisting of 14 female students and 16 male students. The procedure for implementing this class action research consists of planning, implementation, observation and reflection. The results of this study are 2. Student learning outcomes before PTK were an average percentage of 30% completeness, after PTK cycle 1 increased to 77% and at the end of cycle II increased beyond classical completeness by 87% of the minimum score of 85%.

Improving Mathematics Learning Outcomes Through Problem-Based Learning: A Study on Vocational High School Students in Class XI

2025-01-22T08:10:02+00:00

This study contributes to improving the learning process of Mathematics among KKBT 1 SMK 4 Pekanbaru Stage 11 students in the school year 2023/2024 and improving their academic performance in Mathematics. The format of this study was classroom action research (CAR) conducted in two cycles, each consisting of six stages: providing motivation, identifying problems, collecting data, processing data, and proving and drawing conclusions. The study subjects were the students of class XI of KKBT 1 SMK 4 in Pekanbaru, totaling 33 students. Data were collected through observation and testing techniques. The tools used included learning tools, teacher and student activity observation forms, and mathematics learning outcome test forms. The data analysis findings showed that the learning process aligned with the lesson plan, and the students were active in the classroom. In addition, the number of students achieving the KKTP increased, i.e., the basic score was 8 or 24.24%; Cycle I increased to 13 or 39.39%; and Cycle II increased to 24 or 72.72%. Thus, through the application of the problem-based learning model, the learning process of the students of KKBT 1 SMK 4 Pekanbaru class XI, stage F, on the material of scatter diagrams for the even-numbered semesters of the academic year 2023/2024 has been improved, and their performance in mathematics has increased.

The Effect of Contextual Learning Models Assisted by Wordwall Media on Students' Mathematical Concept Comprehension Ability in Elementary Schools

2025-01-22T08:09:46+00:00

This study aims to evaluate the effectiveness of a contextual learning model assisted by Wordwall media in enhancing elementary school students' mathematical concept comprehension. The research used a quantitative approach with an experimental design for a pretest-posttest control group. The sample consisted of two groups: an experimental group taught using the contextual learning model assisted by Wordwall and a control group that followed conventional teaching methods. The instruments used included tests for validity, reliability, difficulty level, and discrimination power. The results showed that the learning process supported by Wordwall was highly effective, significantly increasing students' active engagement in the learning process. Statistical analysis revealed significant differences between the experimental and control groups, with a large effect size, indicating that the contextual learning model assisted by Wordwall significantly improved students' mathematical concept comprehension. Additionally, this approach successfully enhanced students' learning motivation and fostered a more meaningful and relevant learning environment in alignment with the needs of the digital era. The study concludes that applying technology-based contextual learning models such as Wordwall can create a more interactive, relevant, and meaningful learning experience, effectively improving students' learning outcomes. This model is also appropriate for supporting the development of 21st-century skills, such as critical and creative thinking, in today's digital age.

Development of Flip PDF-Assisted Scientific Approach E-Modules to Enhance Mathematical Understanding in Circle Topics for Grade VIII Students

2025-01-22T10:32:44+00:00

The background of this research is the limitation of e-modules that are in accordance with the abilities of students who have difficulty in learning mathematics. This causes the low mathematical understanding skills of students. The goal of this study is to create an e-module based on the scientific approach assisted by flip pdf on circle material that is able to facilitate the mathematical understanding skills of grade VIII students. The development procedure is guided by the ADDIE model. This research was only conducted until the small group trial with subjects consisting of 10 students of SMPN 35 Pekanbaru grade VIII. Data was obtained by utilising interview and questionnaire techniques. The instruments used in data collection were validation questionnaire and student response questionnaire. The findings of the research obtained that e-module have an average validity of 3.52 which is classified as very valid. Meanwhile, the practicality of e-modules is classified as very practical with an average of 3.39. Thus, the e-module produced has met the requirements of validity and practicality, so that it is worth it for use by grade VIII junior high school / MTs students.
