Abstract

The research aims to determine the effectiveness of project-based learning by paying attention to student differentiation to improve computational thinking skills. The research is based on students' computational thinking skills, which are still below standard, namely below of 50% at each stage, including decomposition, pattern recognition, abstraction, and algorithms. This research is classroom action research carried out over three learning cycles. The results of the research show that there is an increase in students' computational thinking skills in each learning cycle given. In the first and second cycles, the level of achievement of students' computational thinking skills reached 22.8% and 54.29%, meaning that what was originally in the very low category became low. After that, in the third cycle the level of achievement of students' computational thinking skills in the high category reached 88.57%. The gain test results in the first and second cycles were in the medium category with n- gain scores of 0.40 and 0.52. Furthermore, in the third cycle, an n-gain of 0.71 or high category level. These results indicates that the implementation of project-based learning according to student differentiation in physics learning was effective in improving computational thinking skills.

Abstract

Critical thinking and problem-solving skills are essential components of 21st-century education goals. Weak problem-solving and higher-order thinking skills (HOTS) can become problematic for students studying physics, particularly in the context of magnetism. To address this issue, efforts are being made to improve physics problem-solving skills through the application of problem-based learning (PBL) and HOTS. The study aims to determine whether students' physics problem-solving skills are better when using PBL-HOTS compared to PBL alone. Additionally, the study aims to determine the improvement and profile of physics problem-solving skills according to Heller after the application of PBL-HOTS on magnetism material. The study employed a mixed-methods sequential explanatory pre-test post-test control group design. The participants were ninth-grade students from SMP Negeri 1 Kersana during the 2021/2022 academic year. The sample was selected using purposive sampling, with Class IX A as the experimental group and Class IX C as the control group. Data was collected using a physics problem-solving test, including descriptions, interviews, and post-test documentation checks. The t-test results indicate that students who applied PBL-HOTS had better physics problem-solving skills than those who applied PBL. Additionally, the N-Gain test showed a moderate increase in students' physics problem-solving skills after the application of PBL-HOTS, with an average N-Gain score of 0.4785. The results of interviews and examination of posttest documentation support Heller's profile of students' physics problem-solving skills. This includes indicators of focusing on the problem (84.69%), describing physics concepts (70.94%), planning solutions (87.81%), implementing problem-solving plans (95.63%), and evaluating solutions (46.88%).

Abstract

Technology is the result of the process of scientific development. 21st century technology has developed rapidly in the scope of education. High-level thinking is an important competency for students in the 21st century. For this reason, learning planning is needed that is able to improve high-level thinking competencies, especially in terms of student interpretation. Many practical lessons at SMA N 1 Balapulang are still not technology-based. This research aims to produce a practical tool based on Arduino UNO to improve graphic interpretation for high school students. This type of research is Research and Development (R & D) and uses a research model, namely ADDIE (Analysis, Design, Development, Implementation, Evaluation). Based on validation by tool experts, it was found that the practical tool media developed received a score of 92.5% in the very good category. The characteristics of the media developed are the Arduino UNO microcontroller with an LM35 sensor to read the temperature of the liquid being measured, the interface of the Arduino UNO is PLX-DAQ software so that it is stored in MS Excel, there is a LKPD developed to make it easier for students during practicum. The results of improving student graphic interpretation seen from the pre-test and post-test obtained an average score from 57.11% to 89.61%. The N-Gain value obtained was 0.72, where there was an increase in graphic interpretation for students in the high category. The results of the analysis of heat change calculations proportional to temperature changes can improve student interpretation of graphs.

Abstract

The Merdeka curriculum organizes the physics subject into concept understanding and science process skills. However, based on interviews and observations at MAN IC Pekalongan, the development of process skills in physics learning is rarely facilitated due to the limited availability of learning media and time. This RnD research aims to develop digital learning media as an alternative solution to these problems. The analysis of learning media needs showed that teachers and students need Interactive E-Modules as learning media, applications of physics in everyday life such as STEM, and a Virtual Lab packaged with interactive and simple language. The E-Module was validated by several experts in material, learning media, and learning and was declared highly feasible with an average score of 4.5 out of 5. The posttest results showed an average score of 59.67 for both the experimental and control classes. The n-gain analysis demonstrated that the E-Module effectively improved conceptual understanding, with an n-gain value of 0.74 (high), and had a positive effect on process skills with an average value of 87.86 for the experimental class and 86.44 for the control class, with a significance value of 0.032 in the independent sample test of both classes.

Abstract

Self-regulated learning is essential for students to be proactive in their learning, and creative thinking is crucial for overcoming challenges and generating innovative solutions. Project-Based Learning (PjBL) has been proposed as an effective method for teaching subjects such as renewable energy, allowing students to apply concepts in a real-world context. However, challenges persist in implementing PjBL, including student adaptation and lack of structured materials. This study aims to assess the impact of the PjBL model on students' self-regulated learning and creative thinking, identify factors that promote self-regulated learning, and understand barriers to developing creative thinking. Conducted at SMA Negeri 11 Sarolangun, this study involved two experimental classes and one control class. Using a mixed-method approach with a sequential explanatory design, this research employed a quasi-experimental method with a non-equivalent control group design. Data were collected using questionnaires, creative thinking tests, and interviews, and analyzed using parametric statistical tests and qualitative descriptive analysis. The results showed that PjBL had a significant positive impact on self-regulated learning and creative thinking, with a supportive learning environment being a key factor. The t-test results showed a significant effect on self-regulated learning (0.002) and creative thinking (0.04), both below the 0.05 threshold. Effect size analysis indicated a high impact on self-regulated learning and moderate impact on creative thinking variable.

Abstract

Soil pH is an indicator of soil quality that is important to note because it  affects the balance of nutrients in the soil. This is important, especially to maintain the fertility of agricultural land. The purpose of this study was to analyze soil quality based on the soil pH of maize and chili plants. The research sample was taken on the agricultural land of Gemuhblanten Village, Gemuh District, Kendal Regency ins October 2022. Sampling was carried out at six points on each of the maize and chili field. The initial pH data obtained was then averaged. It was obtained that the average soil pH of maize plants was 7.75 which was in the "slightly alkaline" criteria. The average soil pH of chili plants is 7.08 which is a "neutral" criterion The soil pH value for maize plants is slightly higher than the good soil pH for maize plants. Meanwhile, the pH of the soil in chili plants meets a good soil pH value for chili plants.
