Critical thinking skills are one of the skills needed in the 21st century. In one of the junior high schools in Pasuruan, students' critical thinking skills are low, so they still need improvement. The goal of this research was the creation of a learning media for an educational kit based on PjBLSTEAM that is considered worthy of being tested for its validity, practicality, and effectiveness in training junior high school students' critical thinking skills on water pollution material. The development procedure was based on the ADDIE model (analyze, design, develop, implement, and evaluate) with data collection techniques using interviews, questionnaires, and pretest-posttest questions. Data analysis techniques were applied using qualitative descriptive techniques, percentage analysis, validity tests, practicality, and effectiveness tests from the paired sample Ttest and N-Gain tests. The results of the media and material validation tests were shown to meet very valid criteria. The results from the teachers and students' feedback showed a very practical percentage. The media was considered effective, as evidenced by the results of the paired sample t-test, which indicated a difference in students' critical thinking scores before and after treatment, and the N-Gain test results, which showed a medium bar value. This research indicates that the learning media developed was valid, practical, and effective for training students' critical thinking skills

The critical thinking skills of students in Indonesia remain below average, presenting a significant challenge in preparing students to meet the demands of the 21st century. This study aims to develop an independent curriculum e-module integrating the scientific approach with Socio-Scientific Issues (SSI) to enhance critical thinking skills. The development process employs the ADDIE model, encompassing five stages: Analysis, Design, Development, Implementation, and Evaluation. The study involved seventh-grade students studying biodiversity. Qualitative data were collected through teacher interviews and questionnaires, while quantitative data were obtained from validator scores, teacher and student evaluations, as well as pre-test and post-test results. Data analysis included qualitative descriptive techniques, percentage analysis, validity and reliability tests, normality tests, homogeneity tests, t-tests, and N-Gain tests. The validation results for media and materials reached 93.75% and 98.21%, respectively. Practicality assessments by teachers and students achieved 95.97% and 87.44%, respectively. The N-Gain test demonstrated moderate improvements across five critical thinking indicators. It can be concluded that the e-module is valid, practical, and effective for use in teaching and learning.

This study investigates science learning outcomes on the topic Matter and Its Changes among seventh-grade students at MTs, with a focus on gender differences. Using a descriptive survey method, the entire population of 77 students (two male classes and two female classes) was involved. Data were collected through post-tests, questionnaires, observations, and interviews, and analyzed quantitatively using the Mann-Whitney U test. The results show that female students had significantly higher average learning outcomes (64.04) compared to male students (45.50). Further analysis revealed that female students performed better at cognitive levels C3, C4, and C5, as well as across all subtopics. Qualitative findings from teacher interviews suggest that this difference is consistent and may be attributed to female students’ ambition and logical reasoning, as observed in class. However, questionnaire data indicate that male students report higher self-confidence. The study concludes that gender differences significantly influence science learning outcomes, with implications for instructional strategies and gender-responsive teaching practice

The 2015 TIMSS and 2018 PISA results show that Indonesia's science performance remains below the international average and declined further in 2022. This indicates students weak critical thinking skills (CTS) in understanding scientific concepts. An effective and interactive learning model is needed. This study aims to compare students' CTS using the traditional game in problem-based learning (TG-PBL) model and the problem-based learning (PBL) model. The research used a quasi-experimental design with a pretest-posttest non-equivalent control group and purposive sampling. Statistical tests included the paired sample t-test, independent sample t-test, and N-gain score. The independent t-test showed a significant difference between TG-PBL and PBL classes (0.000). The paired t-test showed a difference between pretest and posttest in both classes (0.000), with a greater increase in the TG-PBL class. The N-gain in the TG-PBL class was 0.57 (medium category), while in the PBL class it was 0.24 (low category). The highest improvement in the TG-PBL class was in the basic support indicator (0.630), while in the PBL class it was in strategies and tactics (0.398). The TG-PBL model is more effective in improving students CTS. It creates a more interactive, relevant, and innovative science learning environment in junior high schools

Science education in Indonesia faces challenges in improving students’ science literacy skills, which are often still low. The objectives of this study are to assess the impact of using the “ELGASE” learning media on improving students' science literacy skills and to identify differences in science literacy skills before and after the implementation of the “ELGASE” media. The method in this study was pre-experimental involving 22 students of class VIII. Data were obtained through observation, testing, and documentation collection methods, then analyzed using the normality test and the N-Gain test to evaluate changes in scores. The results showed that the use of “ELGASE” media provided a significant increase in students’ science literacy skills. This improvement is measured through a nonparametric test (Wilcoxon), which indicates the difference or comparison of pretest and posttest scores on each indicator. The study results indicate that the use of “ELGASE” media significantly improved students’ science literacy skills, with the N-Gain score for the first indicator being 0.80 (80%) and for the third indicator 0.92 (92%), classified as “Effective” and “Highly Effective”, respectively. Additionally, the second indicator showed an increase of 0.58 (58%), falling into the “Moderate” category, which demonstrates a medium level of effectiveness in enhancing students’ understanding of the taught material. The conclusion of this research is that the “ELGASE” media is proven effective in improving students’ science literacy skills and can be recommended for use in science learning.

Project-Based Learning (PjBL) is often proposed as a way to engage students through authentic tasks, yet classroom observations in junior high schools in Malang indicated that students’ critical thinking and learning motivation were still relatively low. This study examined whether PjBL supported by a mobile application could improve seventh-grade students’ critical thinking and learning motivation on the topic of substances and their changes. A quasi-experimental design was used with 62 students from one junior high school (30 in the experimental group and 32 in the control group). The intervention combined PjBL with a mobile application and supporting materials (modules and student worksheets). Expert review showed that the learning media met acceptable validity criteria, with an average score above 83 percent (high validity). The instruments demonstrated good internal consistency, with Cronbach’s alpha of 0.853 for the critical thinking test and 0.929 for the learning motivation questionnaire. Independent-samples t-tests indicated statistically significant differences between groups (p < 0.05). The experimental group scored higher than the control group in critical thinking (t(60) = 2.33, p = 0.023, d = 1.02) and learning motivation (t(60) = 11.83, p < 0.001, d = 1.13). These results suggest that, in this context, mobile-aided PjBL was associated with higher critical thinking and learning motivation than conventional instruction, and it may be considered for teaching substances and their changes.

Based on WHO data, vaginal infections every year affect women worldwide, around 10-15 percent of 100 million women. Pathological vaginal infections caused by Bacterial vaginosis (BV), Candidiasis, and Trichomoniasis. Abnormal vaginal discharge is an indication of a reproductive tract infection. Therefore, it is very important for women to make early detection of vaginal discharge that they suffer from. However, many women underestimate the presence of vaginal discharge, this is because women have a sense of shame to carry out their genital examinations at doctors, especially by male doctors. In addition, most women do not like the examination using medical procedures because of the feeling of discomfort with the examination procedure. Because of this, in this expansion research, an ATMega 168-based detection device and an expert system-based application were designed forearly detection of vaginal discharge. The method used in this development research consists of several stages including: 1) needs analysis, 2) design, 3) design of vaginal discharge detection tools and applications, 4) testing, 5) evaluation. The results of this research and development resulted in a vaginal discharge detection tool along with an expert system-based leucorrhoea detection application with the certainty factor method.
