Abstract

Kurikulum merdeka was implemented in 2022. The characteristics of the kurikulum merdeka were the development of soft skills and character, focus on essential materials, and flexible learning. The low learning outcomes of students were still a problem. One of the efforts that can be done was to apply the Project Based Learning (PjBL) model assisted by performance assessment. This study aimed to determine the effect of the Project Based Learning (PjBL) model assisted by performance assessment on the learning outcomes of grade VIII students on organ system material. This type of research was Quasi Experiment, with a Non Equivalent Control Group Design research design. The sampling technique used was total sampling. The experimental class used the Project Based Learning (PjBL) model assisted by performance assessment while the control class used conventional methods. Based on the hypothesis test with the t test, the calculated value = 2.654 and ttable = 2.006. From the data shows that if tcalculate > ttable, h1 was accepted, it was concluded that there was an influence of the Project Based Learning (PjBL) model assisted by performance assessment on the cognitive learning outcomes of grade VIII students on organ system material.

Abstract

This research .was based on the results of a preliminary study conducted at SMPN 16 Padang, which showed that students' cognitive learning outcomes were still not optimal in science learning. This research aims to determine the influence of the video-assisted Problem Based Learning (PBL) model on learning outcomes for Indonesian Ecology and Biodiversity Material. This type of research is a quasi experiment with a non equivalent control group design research design. The population in this study were all the 7th grader at SMPN 16 Padang. Sampling used purposive sampling technique. So we obtained one experimental class by applying the video-assisted Problem Based Learning model, namely class VII.6 and one control class with the conventional learning model, namely class VII.7. Data collection was carried out through pre-test and post-test. The data obtained were analyzed using inferential statistical analysis and the results obtained from the similarity test of the two pre-test and post-test averages were respectively 0.067 for the pre-test sig, and 0.000 for the post-test sig, which means that H0 is rejected or there is a significant difference in both classes because sig < 0.05. Thus, it can be concluded that there is a significant influence of the application of the video-assisted PBL model on the learning outcomes of Indonesian ecology and biodiversity material.

Abstract

Cognitive ability is one of the essential aspects emphasized in the Merdeka Curriculum. One of the ways to enhance students’ cognitive ability is by applying the Project Based Learning-STEM (PjBL-STEM) model. This research was motivated by observations conducted on Grade VIII students at SMPN 21 Padang during the 2024/2025 academic year. The observations revealed that although the teacher implemented the PjBL-STEM model, its application was not fully optimal. The purpose of this study was to determine the effect of the PjBL-STEM learning model on students’ cognitive ability on the topic of vibration and wave. This study employed a quasi-experimental method with a posttest control group design. Purposive sampling was used to select the samples. Grade VIII students taught using the PjBL-STEM model served as the experimental group, while another Grade VIII class taught using conventional discovery learning served as the control group. The research instrument was an objective written test. The collected data were analyzed using normality, homogeneity, and hypothesis testing. The t-test results showed a t-count of 10.283 and a t-table value of 2.036, where tcount ≥ ttable. Therefore, H0 was rejected and H1 was accepted, indicating a significant effect of the PjBL-STEM model on students’ cognitive ability in junior high school.

Abstract

The general background of this research is the limited teaching materials equipped with project-based learning assessment instruments as recommended in Kurikulum Merdeka. The purpose of this research is to produce a Project Based Learning (PjBL) based e-module on the structure and function of living creatures topic that is valid, practical and effective.The type of research used is Research and Development (R&D) with 4-D model’s consisting of the stages of defining, designing, developing and disseminating. However, this research was only untill the development stage due to time constraints. The research instruments consist of teacher questionnaires, student questionnaires, validity test questionnaires, practicality test questionnaires, and effectiveness test questionnaires. The data obtained was analyzed using a formula to analyze the results of validity, practicality and effectiveness tests. The research results show that the PjBL-based e-module developed is valid with an average 88%. The level of practicality is practical with an average 88%. The level of effectiveness is effective which is 84% ​​on average. Based on the research results, it can be concluded that the PjBL-based science learning e-module on the material Structure and Function of the Body of Living Creatures meets the valid, practical and effective categories.

Abstract

The aim of this study was to analyse the need for the development of science e-comic as learning media on earth and solar system topic. This research was conducted in 3 junior high schools in Sutera sub-district, based on the results of observations it is known that the school applies the kurikulum merdeka, and uses lecture and discussion methods in the learning process. However, there are obstacles that must be faced by teachers, namely the current package books/printed books are quite limited, so students have enough difficulty if they want to repeat learning material at home. This type of research is Research and Development (R&D) using the 4-D development model. This research instrument consists of a validation questionnaire, a practicality questionnaire, and an effectiveness questionnaire. The data obtained were analyzed using a formula to analyze the results of the validity test, practicality test, and effectiveness test. Based on the above problems, researchers found the right and appropriate media to be developed and can be used easily by students and teachers, namely problem-based science e-comic learning media on earth and solar system material.
