Studying the liver as an excretory organ is still a problem for students. The availability of learning media that can represent learning is urgently required. This study aims to develop and analyze the feasibility and practicality of Android-based flash learning media on the liver as an excretory organ for eighth-grade students. This Research and Development (R&D) uses the Borg and Gall model with a limit of up to stage seven. The results of expert validation show that learning media is included in the "very feasible" category according to media experts and material experts, with the percentage order of 86% and 95%. The media practicality by the teacher's response showed that media was categorized as very practical (94%). Then, student response toward the media was reached 85% and categorized as practical. The test of the effectiveness of learning media on critical thinking skills showed that there was a significant difference between the pretest and posttest scores. The results of this study need to be continued at the next R&D stage to get the feasible product.

Background: Environmental provisions can boost students’ discretionary participation in physical activity (PA) during lunchtime at school. This study investigated the effectiveness of providing PA equipment as an environmental intervention on middle school students’ PA levels and stakeholders’ perceptions of the effectiveness of equipment provisions during school lunch recess. Methods: A baseline–intervention research design was used in this study with a first baseline phase followed by an intervention phase (ie, equipment provision phase). A total of 514 students at 2 middle schools (school 1 and school 2) in a rural area of the western United States were observed directly using the System for Observing Play and Leisure Activity in Youth instrument. Interviews were conducted with stakeholders. Paired-sample t tests and visual analysis were conducted to explore differences in PA levels by gender, and common comparison (with trustworthiness measures) was used with the interview data. Results: The overall percentage of moderate to vigorous PA levels was increased in both schools (ranging from 8.0% to 24.0%). In school 2, there was a significant difference in seventh- and eighth-grade students’ moderate to vigorous PA levels from the baseline. Three major themes were identified: (1) unmotivated, (2) unequipped, and (3) unquestionable changes (with students becoming more active). Conclusions: Environmental supports (access, equipment, and supervision) significantly and positively influenced middle school students’ lunchtime PA levels.

The aim of the research is to identify the effect of the interaction between the e-learning environment and the level of self-learning ability on critical thinking and achievement in mathematics among secondary school students. In order to achieve the objectives of the study, the researcher relied on the semi-experimental approach, where the research tools were in the measure of self-learning ability, electronic achievement test, After verifying the validity of the research tools and their consistency, they were applied to a sample of (35) female high school students in Taif, They were divided into the first two experimental groups (18) and the second (17) according to the level of self-learning ability (high and low). The first group is taught through a virtual e-learning environment and the other through a personal electronic learning environment. The data were processed using the SPSS statistical program and the research reached a number of results, the most important of which are: There was a statistically significant difference (0.05) among the average scores of the students in the post-test of the achievement test among the first experimental group using the virtual e-learning environment, and the general average (14.28) and the second experimental group using the personal e-learning environment and got a general average (15.39), and shows the difference in favor of the second experimental group. There was also no statistically significant difference (0.05) between the mean scores of the students of the two groups in the post-measurement scores of the Critical Thinking Skills Scale. A statistically significant difference (0.05) was found between the mean scores of the students of the experimental groups in the academic achievement and the critical thinking skills scale due to the main effect of the different level of self-learning ability (high / low) For students with high self-learning ability, There were no statistically significant differences at (0.05) between the mean scores of the students of the two groups due to interaction between the e-learning environment (virtual / personal) and the level of self-learning (high / low) in academic achievement and critical thinking skills. In the light of the results, a number of recommendations and suggestions were presented to enhance the critical thinking skills and the achievement of mathematics in secondary school students and in all educational stages, Including the awareness of teachers and teachers of the importance of using e-learning environments in achieving the desired educational goals and attention to the development of thinking skills in general and critical thinking skills in particular to ensure the efficiency of the process of learning and continuous learning process.

This study aimed to determine the effectiveness and validity of a teaching document using Argument-Driven Inquiry (ADI) model with a Contextual Approach to improve students' critical thinking skills in science learning. This type of research was research and development (R&D) that refers to the 4D model. Data collected by the validation sheets, student response sheet, and critical thinking skills test. They were analyzed by using t-test and N-gain. The present research was applied in lower secondary at SMP Negeri 1 Bluto with trial design of One-Group Pretest-Posttest Design. The results of the data analysis show that (1) the learning materials was valid in terms of the results of the validity of the materials with the score of 3.57; (2) learning materials was effective in terms of: (a) the students' responses were categorized as very good with results of 83.2%, (b) students' critical thinking skill increased with an average value of N-gain in grade eight A of 0.74 and 0.75 for grade eight B with a high category. Based on the results of statistical analysis using the t test, the probability value (sig) was 0,000 in the two classes. This means that the significance value was less than 0.05 which means there was a significant difference between the pre-test and post-test results. In conclusion, Argument-Driven Inquiry (ADI) model with a Contextual Approach is proven to be feasible and effective for improving critical thinking skills.

Improving the quality of education in Indonesia can be developed through the implementation of education reform. One form of educational reform can be done by using a learning approach that can assist teachers in producing experts using the STEM (Science, Technology, Engineering, and Mathematics) approach. The initial findings revealed only about 47.8% of elementary school students in Wae Ri'i sub-district (grade V) who still had not achieved satisfactory scientific and mathematical scores according to the minimum passing grade. This study aims to see the effectiveness of the STEM approach in improving the critical thinking skills of elementary school students in Wae Ri'i District. The research method used is an experimental design with Non Equivalent Control Group Design. The research subjects were elementary school students in five (5) elementary schools in Wae Ri'i District. The results shows the sig (2-tailed) value of Equal variances is assumed to be 0.000 <0, 05. Therefore, Ho is rejected and Ha is accepted, which means that there is a significant difference in critical thinking skills after students used the STEM-PBL approach, compared to innovative K13 approach. The average scores of the control class critical thinking skills for the pre-test and post-test were 38 and 79.5. The fixed coefficient is 0.676 and is significant at 0.000. This means that the correlation is positive. Therefore, learning with STEM approach is proven to be effective in improving the critical thinking skills of elementary school students in Wae Ri'i sub-district.
