Abstract

Experimental activity in learning science allows students to develop critical thinking, active learning, creativity, scientific, and collaboration skills. This study aims to create an alternative experimental design for learning force and motion, which analyzes the kinematics aspect of handmade rubber cars using Tracker. The method used is the R&D method with the ADDIE model to develop the experimental design on the material of force and motion for grade 7 junior high school students. The Tracker application was used to evaluate trial data on handmade rubber cars to calculate the acceleration, force, and time needed by the vehicle with varying the number of rubber turned. Then, to evaluate the experimental design, this study used a questionnaire instrument, and the experimental design was implemented in four classrooms of junior high school students in the seventh grade. The results were examined based on the percentage of students who answered each statement. The kinematics analysis of handmade rubber cars using Tracker shows that the more significant the number of turns given to the vehicle, the more acceleration and force decrease. Meanwhile, the car still travels longer when the number of rubbers turned is higher. This happened because the car took longer to reach maximum speed, and the rubber band detaches when more rubber is turned on. Moreover, the experimental activity of making handmade rubber cars using Tracker was well received by students, as seen from the response questionnaire scores, which were categorized as high. This study suggests that further research can implement different independent variables as the experiment design parameters based on this result. Teachers and other researchers can utilize the developed experimental design as an alternative strategy in learning force and motion topics.

Abstract

An experiment thought to be simple is included in various textbooks to test the accuracy of the principle that as the depth of the liquid increases, the pressure it exerts on the surface increases. The enriched prediction, observation, and explanation (POE) strategy was used by combining 3D animations with the interaction, convenience, and three-dimensional visualization of augmented reality (AR) to eliminate this misconception, which is still common today. Thus, this study aimed to perceive a conceptual change in teacher candidates regarding the pressure of liquids. The findings showed that teacher candidates made mistakes in the Prediction stage of POE. It was determined that the candidates observed the distances taken horizontally through their activities during the Observation stage, commented on how the distances changed, and perceived their mistakes. The Explanation stage of POE showed that teacher candidates became aware of the discrepancy between their predictions and observations, which prompted them to think. In this respect, it can be said that establishing the depth context in liquid pressure through the path taken by the fluid moving in the form of a horizontal launch through a small hole opened on the side surface of a cylindrical bottle provides a significant conceptual change. The conceptual change of the candidate teachers was significantly improved in a positive way, and the contradiction between their predictions and observations was eliminated by discussion

Abstract

This research aims to develop a set of e-diagnostic four-tier tests on Momentum topics that can be utilized to identify students' learning difficulties and misconceptions. The tests are to be valid, reliable, and effective. This research and development (R&D) project employed the 4-D model, which encompasses the following four stages: Define, Design, Develop, and Disseminate. The Define stage entailed a comprehensive needs analysis and identification of critical issues, while the Design stage encompassed the formulation of e-diagnostic four-tier test grids and instruments. The development stage comprised the implementation of development activities, expert validation, product testing, and the final assembly of the product. The dissemination stage involved the publication of the results of the development of the e-diagnostic four-tier test. The test was constructed in the form of a five-option multiple-choice test. Each question comprises four tiers or levels, ranging from questions, confidence levels, and reasons to the subsequent confidence level. The data collection instrument includes an assessment sheet for product validity, scoring guidelines, and a Likert scale for determining the practicality of product use. The data analysis technique employs the following formulas: (1) Aiken's V for testing validity, (2) Cronbach Alpha for determining reliability, (3) probability of answering correctly to ascertain the level of difficulty of the items, (4) differentiating power to determine the differentiating power, and (5) percentage to measure the level of misconception. The outcome of this research is a series of four-level diagnostic multiple-choice tests accompanied by explanatory material designed to address potential misconceptions. The tests have been evaluated rigorously for validity, item analysis, practicality, and effectiveness.

Abstract

Computed tomography (CT) is one of the most important imaging methods in clinical medical practice. Students of medicine have an opportunity to learn about its principles during the classes of the medical biophysics. For a high-quality understanding of the function of CT and to increase the curriculum attractiveness, it is advisable to include such clinical equipment or its simulator in the practical lessons. However, regarding operational safety and related maintenance, CT devices are very expensive and demanding. Therefore, the aim of this work was to create a cheap, operationally easy, and safe CT simulator. The device simulates the principle of CT by transmitting visible light through cubes with a built-in filter of defined attenuation simulating various human tissues. During hands-on training, students first measure radiation intensities without a sample (I0) and with single cubes (Ii). In the second task, students measure a matrix consisting of four different cubes, irradiating the matrix from different directions and simulating the CT principle. Based on the measurements, the students calculate the linear attenuation of each cube and the corresponding CT numbers and compare the results. The simulator's control is intuitive, provided measurement results are consistent and automatically fed into an interactive report that compares the measured data with the students' calculations, verifies the results, and finally stores them in the database. The main benefit of the study is to bring cheap and effective tools for the demonstration of the CT principle, which can operate each student during the practical lessons, followed by supporting teaching materials.

Abstract

This meta-analysis investigates the impact of integrating Project-Based Learning (PjBL) with STEM (Science, Technology, Engineering, and Mathematics) on Technology Engineering Literacy (TEL) and student learning motivation. The study aims to provide valuable insights for educators, curriculum developers, and policymakers, guiding the design of more engaging learning experiences and supporting innovative educational practices. The research followed a systematic meta-analytic approach, including defining the research problem, setting inclusion criteria, devising a literature search strategy, selecting studies, extracting data, performing statistical analysis, and interpreting results. Analyzing 33 articles from international and national journals, the study reveals that PjBL-STEM significantly enhances TEL, particularly at the high school and college levels, and boosts student motivation, with more pronounced effects observed in high school and college compared to junior high and elementary schools. The model shows a strong impact on TEL in Physics but has lower effects in Science and Biology. For student motivation, significant improvements are noted in Science, Mathematics, and Social Sciences, while effects are less in Chemistry and Physics. The research highlights the effectiveness of PjBL-STEM at higher educational levels and underscores its potential to improve TEL and motivation, though further research is needed to refine adaptation strategies for different educational contexts.

Abstract

Science learning provides an opportunity to prepare students with 21st-century Engineering Design Thinking skills (EDT). EDT is a means of looking at and addressing daily real-world problems that greatly need solutions. This study aims to explore students’ EDT skills on alternative energy issues, specifically problem identification and developing ideas and plans. This research is a qualitative exploratory study in a senior high school in the Jember district. The learning design in this study uses the Science Learning through Engineering Design (SLED) models. Research data was gathered through observation and students’ worksheet documents. Content analysis is used as an approach to analyzing data. The results indicated that EDT trains students’ thinking processes to become more critical through problem identification and creativity in developing new ideas and imagination. EDT provides opportunities for students to combine their creativity and critical thinking to produce innovative design solutions. It improves students' epistemic comprehension while studying and helps them acquire relevant knowledge. This research is expected to be supplementary information for teachers to integrate EDT into their learning so that students can achieve meaningfulness and epistemic understanding.

Abstract

This study reports a basic experimental procedure to measure light transmission through some transparent materials through Arduino microprocessors. The basic experimental material is made up of materials used daily by elementary students, and the procedure is very simple and can surely be employed for teaching activities as STEM education material. The STEM material particularly focuses on transmission rates as a function of the thickness of the material. The absorption rates are experimentally measured using a specially designed box with two separated parts with a small window and an Arduino Uno microprocessor connected to an appropriate light detector structured as STEM education material. The experimental resolutions are managed for two materials, namely blue acetate and red acetate, with different thicknesses. The absorption coefficients are found to be 2.89 mm-1 for blue acetate and 1.54 mm-1 for red acetate. This work offers inexpensive teaching material that can create an education environment where students can feel dynamic and encompass the acquisitions of Science, Technology, Engineering, and Mathematics.
