Teaching and Learning Hooke’s Law Using Physical, Interactive Software and Blended Approach: An Overview
At present, with technological advancement and changes in students’ preferences, there are both challenges and opportunities to enhance the teaching and learning of subjects in science, technology, engineering, and mathematics (STEM). In this article, we explore reported works in established databases on the topic of Hooke’s Law, to see the approaches used in teaching and learning of the topic. Searches were performed in Web of Science, Scopus and Google Scholar databases, after which manual filtering for relevant articles was carried out by reading and browsing through the abstracts. Based on the types of works, the articles were separated into three parts: physical, interactive software, and blended. In total, 21 relevant articles were reviewed. The data obtained can be separated into three categories: physical, interactive software, and blended. Of the three, blended approaches were used the least. To further explore the topics discussed in the articles related to Hooke’s Law, a bibliometric study was performed. From the results, we found that, with the advantages offered by the blended approach, and none using artificial intelligence, there is still room for improvement to enhance the teaching of Hooke’s Law, specifically, and generally, on introductory physics subjects.

It is necessary for teachers to demonstrate various phenomena related to water waves for better students' understanding. However, it is often less ideal to carry out the experiment using a conventional setup outside the laboratory setting due to its lack of portability. This study develops a portable ripple tank to enhance the teaching experience in wave phenomena and characteristics. Traditional ripple tanks face limitations in terms of size, portability, and observation clarity, prompting the need for innovation. The proposed portable ripple tank addresses these challenges by integrating low-cost materials and electronic components to improve accessibility and functionality. This study aimed to design and evaluate a portable ripple tank integrated with digital components to enhance classroom usability and learning outcomes. Through the adoption of the ADDIE instructional design model, the study systematically analyzes the needs of 20 physics teachers through semi-structured interviews and direct observations, which enables the key issues with existing ripple tanks in school laboratories to be identified. Subsequently, the portable ripple tank was designed and developed, incorporating features such as a digital stroboscope and an alternative power supply for enhanced usability. In the implementation, five-wave experiments were conducted using the tool to evaluate its effectiveness in teaching key wave concepts such as reflection, refraction, diffraction, and interference. In evaluation phases, the effectiveness of the portable ripple tank is assessed by three expert teachers, who assess the tool’s usability and effectiveness in classroom settings, confirming its practicality, affordability, and impact on students’ understanding. This research contributes to the advancement of wave physics education by providing educators with a versatile and user-friendly experimental tool, enabling students to visualize and understand complex wave concepts with ease.

Comparing The Acceleration Due to Gravity using Traditional Method Versus Tracker Video Analysis: Experiments in A Simple Pendulum
This study used a simple pendulum to compare the accuracy and precision of the traditional method and Tracker video analysis in determining the acceleration due to gravity (g). The experiment involved two groups of participants: science teachers in the Philippines, who used the traditional method, and high school students in Uzbekistan, who employed video analysis. Both groups conducted multiple trials by measuring the period of the swinging pendulum. Data were collected by manually recording the pendulum’s motion with a stopwatch or through video analysis software, and the resulting periods were used to calculate g. The data were analyzed by comparing the measured values of g from both methods and assessing the precision and accuracy of each. The results indicated that the traditional method provided more accurate g measurements than the video analysis method, though both methods yielded results close to the accepted average value of 9.81 ms−2. The study suggests that both methods are feasible, but user experience and familiarity with the tools significantly impact the results.

The Effect of STEAM Integrated Project Based Learning on Students’ Critical Thinking on Static Fluids Concept
This study aims to see the effect of project-based learning (PjBL) integrated with the STEAM approach (Science, Technology, Engineering, Arts, and Mathematics) on students' critical thinking skills on static fluid material in grade XI of high school. The research employed a quasi-experiment with a two-group pretest–posttest control group design. The sample consisted of two classes, namely class XI MIA 2 (experimental group) and class X MIA 1 (control group), which were selected using a simple random sampling technique, with each class consisting of 36 students. The research instrument used was an essay test designed to assess students' critical thinking skills. The data were analysed using a t-test to determine the differences between groups. Pretest results indicated comparable initial critical thinking abilities between the experimental and control groups. However, following the implementation of STEAM-integrated PjBL, the experimental group demonstrated a significant improvement in post-test scores compared to the control group. This improvement was reflected in a higher percentage increase in critical thinking skills, indicating the positive impact of the integrated approach. The effectiveness of this intervention was further supported by a high score on the relative effectiveness test, emphasizing its value in enhancing critical thinking skills. These findings suggest that active, interdisciplinary learning strategies can effectively enhance students' analytical and problem-solving abilities, better preparing students for real-world challenges through deeper engagement and creative thinking.

Teacher Support Adaptivity in Physics Classroom for Gifted Students
Gifted students have varying learning characteristics and learning needs. In this respect, adapted support to their skills and learning characteristics during academic activities plays a key role in engaging in learning activities and achieving learning goals. Accordingly, this study focuses on teachers' support of adaptivity competencies during microteaching from the perspective of both gifted and nongifted students. To this end, a descriptive comparative method was adopted, and gifted (n=124) and non-gifted (n=205) students joined the study. An adapted version of the Questionnaire on Teachers’ Support Adaptivity was employed for collecting data. Data were quantitatively analysed including MANOVA and ANOVA. The results revealed that both groups perceived the support they received from teachers as slightly above and below average, meaning that teachers were not competent. In deep analysis, results indicated a significant difference between the two groups, but no difference between girls and boys. That is, gifted students are more disadvantaged than nongifted students since their teachers lack strategies in adapting their support to meet the different academic needs of their students. This study recommends that teachers need pre-service or in-service training to offer quality and appropriate support for gifted students, which is crucial in achieving learning goals.

Simulator for Teaching Computed Tomography Principle
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.

POE Activity Enriched with Augmented Reality: Conceptual Change on Pressure in Liquids
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

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.
