Pengaruh Model Think Pair Share (TPS) Terhadap Kemampuan Berpikir Kritis Materi Statistika

The fact of the problem of low critical thinking skills of students is 65.49% in accordance with the provisions of the KKM which is 70. In addition, from the results of observations obtained students are less able to analyze ideas to solve a problem. In addition, students are reluctant to do practice questions that would enable students to be competent in determining strategies and conclusions in solving questions. One of the models indicated as being able to overcome the problem of low critical thinking skills in statistical material is the TPS Model. The study aims to determine whether there is an effect of the TPS model on the critical thinking skills of statistical material for class VII students of SMP Negeri 3 Kotabumi, North Lampung in the 2023/2024 Academic Year. This research method is quantitative experimental with a quasi-experimental design. The form of quasi-experimental chosen is nonequivalent control group design. Then samples were taken from two classes, namely one class VII D for the experimental class using the TPS model and one class VII C using the model commonly used by teachers. The results of data analysis using the t-test, obtained tcount = 3.102 and ttable 1.990 then tcount> ttable so that H0 is rejected, and Ha is accepted. This means that there is an influence of the TPS model on the critical thinking skills of statistical material for class VII students of SMP Negeri 3 Kotabumi

Perangkat Pembelajaran Mata Kuliah Kapita Selekta Matematika SMP Terintegrasi Nilai Islam

To produce graduates with new literacy skills, such as data literacy, technology literacy, and human literacy, combined with noble character, precise learning planning is essential. One such plan is the Semester Program Plan (RPS) integrated with Islamic values, aligning with the needs of Industry 4.0 graduates and the vision of the study program, faculty, and university. This study aims to develop an Islamic-integrated RPS that is feasible and effective for the Selected Topics in Junior High School Mathematics course. The research subjects were first-semester students of the Mathematics Education Study Program, Faculty of Teacher Training and Education (FKIP), Universitas Muhammadiyah Pringsewu Lampung, for the 2024/2025 academic year. The research employed the 4-D development model (Define, Design, Develop, Disseminate) by Thiagarajan. Data collection techniques included expert assessment sheets, observation sheets for learning implementation and student activities, student response questionnaires, and learning outcome tests. Data analysis was conducted using average scores and percentages. The findings of this study include four stages. In the define stage, data revealed that the characteristics of students include being closer to peers for sharing ideas and providing mutual support, being independent, and having a high curiosity about technological advancements. In the design stage, an RPS integrated with Islamic values was developed. In the develop stage, a feasible and effective RPS was obtained. In the disseminate stage, the RPS was used by the course instructor. With a feasible and effective learning tool integrated with Islamic values, it can enhance students' academic achievement and character development.

Pembelajaran Aljabar yang Kontekstual: Studi Eksperimen Model CTL dan Media Kartu Elemen Aljabar

This research focuses on assessing the enhancement of students' performance in mathematics through the application of the Contextual Teaching and Learning (CTL) approach, supported by algebra element cards specifically in the area of algebraic expressions. The study employs a quantitative method with a comparative framework. The target population includes seventh- grade students from UPT SMPN 2 Gading Rejo. A sample was drawn from two classes selected by a cluster random sampling method, where VII A served as the experimental group utilizing the CTL approach along with algebra element card media, while VII B acted as the control group engaging with a traditional teaching model that also incorporated algebra element cards. The subsequent data analysis utilized the Mann-Whitney Test due to the data not satisfying the normality assumption. The results of the data analysis show that , thus it can be concluded that the CTL learning model assisted by algebra element card media has a significant effect on improving the mathematics learning outcomes of the 7th-grade students of UPT SMPN 2 Gading Rejo

Implementasi Pembelajaran Teknologi Informasi Berbasis Video Pada Mahasiswa Semester 1 Program Studi Matematika Universitas Muhammadiyah Kotabumi

This study aims to determine the effectiveness of implementing video-based Information Technology learning on the learning outcomes of first-semester students in the Mathematics Study Program at Universitas Muhammadiyah Kotabumi. The research method used is a pre-experimental design with a one-group pretest-posttest model. The research sample consisted of 28 students. Data were obtained through pretest and posttest assessments, as well as a student perception questionnaire. The analysis results showed that the average pretest score was 56.82 with a standard deviation of 6.47, while the posttest average increased to 78.18 with a standard deviation of 6.79. The Shapiro-Wilk normality test indicated that the data were normally distributed, with significance values of 0.645 for the pretest and 0.151 for the posttest. The paired sample t-test produced a significance value of 0.000 (<0.05), indicating a significant difference between pretest and posttest scores. In addition, the analysis of student perception questionnaires showed an average score of 4.38, categorized as “strongly agree.” Thus, video-based Information Technology learning is effective in improving learning outcomes and receives a positive response from students.

Teknologi dan Pembelajaran : Memanfaatkan Macromedia Flash dalam Model Learning Cycle 5E untuk Mendukung Pemahaman Konsep Matematis

This study aims to determine the effect of applying the Learning Cycle 5E model assisted by Macromedia Flash media on the understanding of quadrilateral concepts by seventh-grade students at SMP Islam Alfalah Abung Tinggi. This research uses a quasi-experimental design with the Nonequivalent Control Group Design method. The sample consists of two classes, with the experimental class taught using the Learning Cycle 5E model assisted by Macromedia Flash, and the control class taught using traditional learning models with PowerPoint. Data were collected using a validated descriptive test and analyzed using t-test to examine the differences between pretest and posttest scores. The analysis results show a significant effect of the Learning Cycle 5E model assisted by Macromedia Flash on improving students' concept understanding, with a t-value = 2.863 > t-table = 1.671, indicating that the alternative hypothesis is accepted, and the null hypothesis is rejected. This finding contributes to the development of mathematics education, specifically in enhancing the understanding of quadrilateral concepts through more interactive and engaging teaching methods.
