Preservice Science Teachers’ Perceptions of Learning Difficulties in Organic Chemistry at an Indonesian University
type: item
description: This study examined preservice science teachers’ perceptions of learning difficulties in Organic Chemistry and their relationship with achievement in General Chemistry. A quantitative descriptive–correlational design was employed. The participants were 103 undergraduate students enrolled in the Science Education program who were taking an Organic Chemistry course, selected through total sampling. Data were collected using a four-point Likert-scale questionnaire measuring perceived learning difficulties and analyzed using SPSS 23. The results indicated that students’ perceptions of learning difficulties were distributed across high and low levels. Among the assessed indicators, problem-solving and analytical skills were perceived as the most challenging. No significant differences were found in perceptions based on gender. Meanwhile, a significant positive correlation was identified between General Chemistry achievement and perceived learning difficulties in Organic Chemistry (R² = 0.91), indicating a strong association within the study sample. However, this association should be interpreted cautiously due to the correlational design of the study. These findings suggest that students’ understanding of foundational chemistry concepts plays a crucial role in shaping their learning experiences in Organic Chemistry and should be strengthened to support more effective instruction.

type: item
description: Science learning media play an important role in the learning process because science is closely related to everyday life and helps students understand themselves and their environment. This study aims to examine the effect of the Project-Based Learning (PjBL) model assisted by miniature media on students’ learning outcomes and creative thinking skills in the solar system topic at SMP Negeri 17 Medan. This research used a quasi-experimental method with a pretest-posttest control group design for learning outcomes and a one-posttest control group design for creative thinking. The sampling technique applied was cluster random sampling, where each class was treated as a cluster. Two classes were randomly selected as samples: class VII-2 as the control group receiving conventional instruction, and class VII-3 as the experimental group taught using the PjBL model assisted by miniature media. The research instruments consisted of a multiple-choice learning achievement test and a creative thinking observation sheet based on Torrance’s indicators of fluency, flexibility, originality, and elaboration. The instruments were validated by experts and pilot-tested to ensure validity and reliability. Data were analyzed using a one-tailed t-test with SPSS version 30. The results indicated that students taught using the PjBL model with miniature media achieved higher learning outcomes and creative thinking skills than those taught conventionally. The t-test results showed significance values of 0.001 < 0.05 for both learning outcomes and creative thinking. Therefore, the PjBL model, assisted by miniature media, positively and significantly influences students’ learning outcomes and creative thinking skills on the solar system topic at SMP Negeri 17 Medan.

Systematic Literature Review: The Influence of Learning Media on Student Learning Outcomes on Solar System Material
type: item
description: Learning about the solar system at the junior high school level poses challenges due to its abstract nature, making conventional methods less effective. This study aims to analyze the effect of learning media on junior high school students' learning outcomes on solar system material using the Systematic Literature Review (SLR) method. Research data were collected through Google Scholar using the PRISMA (Preferred Reporting Items for Systematic Reviews-Meta Analysis) technique through four stages: identification, selection, eligibility, and inclusion. From 240 articles, seven national journal articles were selected as research data because they met the criteria determined by the researcher in the last five years. The literature review shows that interactive learning media such as Flashcards, Augmented Reality (AR), Interactive Multimedia, Articulate Storyline, Virtual Reality (VR), Science Monopoly, and Unity 3D can make abstract solar system material more concrete, thereby increasing students' enthusiasm, spirit, motivation to learn, and learning outcomes, as well as helping the right brain to remember concepts. The immersive, contextual, and enjoyable learning experience provided by learning media encourages deeper student engagement. The integration of appropriate learning media is essential to improve student learning outcomes, and the evaluation and updating of learning media must be carried out continuously to adapt to the characteristics of 21st-century students.

The Relationship Between Scientific Literacy Skills and Self-Efficacy of Junior High School Students in Science Learning
type: item
description: This study aimed to determine the level of scientific literacy skills and self-efficacy of junior high school students in science learning. This research was conducted through the administration of a scientific literacy test and a self-efficacy questionnaire. The research instrument consisted of a scientific literacy test in the form of essay questions that measured three indicators of scientific competence, and a self-efficacy questionnaire adapted from Bandura with indicators of magnitude, strength, and generality. The results showed that students' scientific literacy level was in the very low category, with the majority of students (81.1%) only reaching the nominal literacy level. It indicates that although students can recognize basic concepts in science, they still have difficulty explaining scientific phenomena and using scientific evidence logically. Meanwhile, students' self-efficacy level is generally in the moderate category, although it is still relatively low in some indicators, such as generality. The correlation test shows a significance value of 0.305 > 0.05 with a Pearson correlation coefficient of 0.098, which means there is no significant relationship between scientific literacy skills and self-efficacy. The coefficient of determination of 0.0096 indicates that the contribution of scientific literacy to self-efficacy is only 0.96%, while other factors influence the other 99.04%. The analysis showed no significant relationship between students’ scientific literacy skills and self-efficacy, as scientific literacy contributed only minimally and was largely influenced by other factors.

THE EFFECT OF ARGUMENT DRIVEN INQUIRY (ADI) MODEL ON STUDENTS' ARGUMENTATION SKILLS IN SCIENCE LEARNING
type: item
description: This study aims to analyze the effectiveness of the Argument Driven Inquiry (ADI) learning model in improving students' argumentation skills in science learning. The method used is a systematic literature review (SLR) with reference to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. The review process was carried out through four stages, namely identification, screening, eligibility determination, and inclusion, so that relevant articles were published in the range of 2018 to 2025. The results of the study show that the ADI model is consistently able to improve students' skills in building data-based arguments, evaluating peer arguments, and reflecting on conceptual understanding. Compared to conventional learning and regular inquiry models, ADI has proven to be more effective because it integrates scientific practice, collaboration, and critical thinking skills. A number of studies have also reported a significant increase in posttest results and are inclusive of students with different academic abilities. Thus, the ADI model can be used as an effective learning strategy in supporting the mastery of science concepts as well as the development of 21st-century competencies, including critical thinking, creativity, problem-solving, and communication.

THE EFFECT OF STEM INTEGRATED PROBLEM-BASED LEARNING MODEL (PBL) ON STUDENTS™ LEARNING OUTCOMES ON HUMAN RESPIRATORY AND EXCRETION SYSTEM
type: item
description: Learning at UPT SMPN 1 Sutera seems to be still low, this is because the learning model used by teachers is still not appropriate and the discussion process has not been carried out well. One way to overcome this problem is to apply the STEM integrated Problem-Based Learning (PBL) model. This research aims to determine the effect of the STEM integrated Problem-Based Learning (PBL) model on student learning outcomes in human respiratory and excretory system material at UPT SMPN 1 Sutera. The type of research used in the research is Quasi Experiment, namely a research method to find the effect of certain treatments on others under controlled conditions. The design used in this research is the Non-Equivalent Control Group Design. The population in this study were class VIII students at UPT SMPN 1 Sutera. The sample in this study consisted of two classes, namely the experimental class and the control class which were taken using a purposive sampling technique. The instruments used consisted of an observation sheet on the implementation of the STEM integrated PBL model, pre-test and post-test questions. The research data obtained was then analyzed through descriptive statistical tests and inferential statistics using SPSS version 25. Based on the results of the analysis in hypothesis testing, it showed that there was a significant average difference between the control and experimental classes. The results of research hypothesis testing were found to be 0.000 and smaller than 0.05. Thus, it can be seen that the significant difference between Ha is accepted and H0 is rejected, so there is an influence. The conclusion from the hypothesis test is that there is a significant influence between students' scores using the STEM integrated PBL learning model. So H0 is rejected and Ha is accepted. So there is an influence of the STEM integrated PBL model on student learning outcomes.

THE IMPACT OF IMPLEMENTING NUMBERED HEADS TOGETHER COOPERATIVE LEARNING MODEL ON THE COMMUNICATION SKILL OF STUDENT AT JUNIOR HIGH SCHOOL 3 TEBO
type: item
description: Low student communication skills have been the cause of this research, which had an impact on learning outcomes because there had not been training on students' communication skills through the application of appropriate learning models. The learning process, which still uses conventional learning models, namely group discussions, has not made each student active and responsible for group assignments and has not trained communication skills in scientific arguments. Therefore, an appropriate learning model is needed, one of which is the Numbered Head Together (NHT) type cooperative learning model. The aim of the research is to determine the effect of implementing the NHT type cooperative learning model on the communication skills of SMPN 3 Tebo students. The research uses a Quasi-Experimental type of research with a Nonequivalent Control Group Design. The research began with a pretest in the experimental class and control class, then treatment was given to the experimental class, and at the end of the learning process, a posttest was given to both classes. Samples were taken using purposive sampling technique. The test instrument consists of 13 description questions. Data were analyzed using Microsoft Excel to carry out prerequisite tests and hypothesis tests on overall communication skills and each ability indicator. The results of the research showed that there was an increase in students' overall communication skills between before and after treatment. Through the Mann Whitney test with Zcount -5.32 and Ztabel 1.96 with the criterion that H0 is accepted if “Ztabel ≤ Zcount ≤ Ztabel, then Zcount -5.32 < -Ztabel -1.96, then H0 is rejected, and H1 is accepted. It can be concluded that there is a significant influence of implementing the Numbered Head Together type learning model on the communication skills of students at SMP Negeri 3 Tebo Regency.
