Abstract

Through the use of interactive 3D media, this study aims to examine how the Discovery learning model affects seventh-grade students' academic achievement. This research is motivated by the insufficient diversity of learning media utilized in the classroom. A nonequivalent control group design is applied in the research approach, which is quasi-experimental. The experimental class will implement the Discovery Learning model utilizing 3D media, while the control group will use the same model without the support of 3D media. The employed sample method is purposive sampling. A student response questionnaire and an exam with twenty-four objective questions make up the research tools. Parametric tests, particularly t-tests, were used for data analysis, along with tests for normality and homogeneity. Results of the student response questionnaire regarding with the use of interactive 3D media, the Discovery Learning model achieved a 95% success rate, which is considered excellent. A total implementation rate of 97.94% was determined to be indicative of successful implementation of the Discovery Learning Model accompanied by interactive 3D media, according to the observation data. The t-value of 2.18 is higher than the t-table value of 2.00, leading to the rejection of H₀ in the hypothesis test. This indicates that student learning outcomes in grade VII of senior high school are significantly influenced by the Discovery Learning Model supported by 3D interactive media covering material about the Earth and the solar system.

Abstract

This study used a quasi-experimental design with a nonequivalent control group design to examine the effect of the Problem-Based Learning (PBL) model assisted by TikTok videos on students’ cognitive learning outcomes in ecology and biodiversity topics. The study was conducted with seventh-grade students at SMP Negeri 22 Padang using a quantitative approach. The sample consisted of two classes selected through purposive sampling, with class VII.A as the experimental group and class VII.B as the control group. Data were collected using a 20-item multiple-choice test administered before (pretest) and after (posttest) the intervention. The results showed that the average posttest score of the experimental group (79.69) was higher than that of the control group (65.78), with a t-value of 4.10 exceeding the t-table value of 2.00 at a significance level of 0.05. These findings indicate that the implementation of the PBL model assisted by TikTok videos has a significant effect on improving students’ cognitive learning outcomes. The integration of problem-based learning activities with short video media provides a more engaging, interactive, and contextual learning experience in science education.

Abstract

This research explores the problem of low academic performance in science among students at SMP Negeri 2 Payakumbuh. To address this challenge, the application of a suitable learning model is deemed crucial. The Student Teams Achievement Division, a model of collaborative education, along with the incorporation of Zep Quiz technology, is proposed as a potential approach to improve students' comprehension of the topic Elements, Compounds, and Mixtures. The study utilized a quasi-experimental design with a non-equivalent control group format. The participants were eighth-grade students from the 2024/2025 school year, class VIII.9 was designated as the experimental group, while class VIII.8 served as the control group, selected through purposive sampling. The class that participated in the experiment was taught with the STAD approach, aided by Zep Quiz, whereas the control class utilized traditional teaching practices. To gather data, pre-tests and post-tests were administered, followed by analysis of the data for normality, homogeneity, and hypothesis testing, which was performed using Microsoft Excel. The results of the t-test indicate a significant distinction between the experimental and control groups (tcount = 2.83 > ttable = 2.00). These results suggest that applying the STAD cooperative model, aided by Zep Quiz media, significantly enhances students’ learning outcomes in science. The model encourages collaborative learning, active student involvement, and interactive digital-based formative assessments, leading to a more effective and engaging learning experience.

Abstract

This research is motivated by the importance of creative thinking skills in today's learning environment. This can be enhanced through the application of innovative learning models. One such approach is the Project-Based Learning model with a STEAM approach. This study aims to determine the effect of the Project-Based Learning model with a STEAM approach on the creative thinking skills of eighth-grade students at SMP Negeri 27 Padang. This study employed a quantitative method using a Quasi-Experimental method with a Non-Equivalent Control Group Design. The Project-Based Learning (PjBL) model with a STEAM approach was applied to the experimental class, while the conventional learning model was applied to the control class. Two classes served as sample groups, selected by purposive sampling. The research instruments used were observation sheets on the implementation of the Project-Based Learning (PjBL) model with a STEAM approach, descriptive test questions, and a questionnaire assessing student responses to the Project-Based Learning (PjBL) model with a STEAM approach. Data analysis was performed using normality tests, homogeneity tests, and two-mean difference tests. Statistical analysis in this study was performed using Microsoft Excel. The results of the study were obtained, based on the hypothesis test, the t-value was 5.70 ≥ t-table of 2.00. This indicates that there is a significant average difference, so that the Project Based Learning learning model with the STEAM approach has a significant effect on the creative thinking skills of class VIII students at SMP Negeri 27 Padang.
