“…This activity is important because it refers to the results of Sharma's (2005) study that 46% of S1 and S2 students in physics education were still having difficulties in making graphics and also the students' ability to interpret graphs was very weak which was only 13%. The same finding was also reported by Subali et al (2017) that physics education students who take Basic Physics courses still have not mastered the competence of analyzing data and drawing conclusions from graphical displays. Therefore, the development of this experimental tool is expected to help and facilitate students in practicing graph analysis properly.…”

Energy is one of the basic concepts in physics which is included as an abstract concept that is not easily captured by students to its physical properties. Therefore it is necessary to optimize the experimental tool in physics learning, especially in the learning of mechanical energy to facilitate understanding the concept. Technology research is growing rapidly and is able to contextually present abstract phenomena that are sensor-based technology and one of them is an ultrasonic sensor. This study aims to develop a mechanical energy experimental tool using ultrasonic sensors to facilitate students in understanding the concept of energy. The development of the experimental tool used research and development methods. To test the feasibility of the experimental tool developed and the accompanying practicum module, a series of feasibility tests have been carried out including calibration tests, feasibility tests by physicists, and empirical tests by users. The instrument used is a checklist item compiled based on the standard indicators of the feasibility of an experimental tool. The results of the development showed that the experimental tool had a precision percentage of 98.1% and a high accuracy of 99.99% with a value of t = (0.383 ± 383X10 -4 ) s. Based on the feasibility test by physicists 93.75% of indicators as standardized experimental tools have been achieved, as well as the experimental modules fulfilling 90.90% of the standard set. Similar results were also report by users that the experimental tool was feasible to be used in schools' level, but there were still obstacles related to the sensitive nature of ultrasonic sensors with surrounding movements and constraints in making variable variations to be tested which had an impact on the less optimal graphic display.

“…Çevik (2015) also resulted that feedback in online learning activities is to improve students' ability in problem solving. Subali et al (2017) also supports that experiments using computer programs help students to improve students' literacy skills, particularly in designing graphs and predicting.…”

The purpose of this study is to examine the effect of the use of virtual labs on problem-solving ability of students to the concept of electricity. The subjects were students of physics education at Mataram University. Students were divided into two groups: experimental and control group. The research instrument used was in the form of problem-solving ability tests on electricity concept. The tests employed the form of essay that represent concepts about electricity being studied. The results showed the effect of the use of virtual labs on problem-solving ability of students to the concept of electricity. It can be seen from the different improvement of problem-solving ability in both groups. Problem-solving ability of experimental group is higher than the control group. From the analysis of these problem-solving steps, it can be seen that general students in both classes have the same ability to identify problems and define goals. In the next step, the different improvement in problem-solving skills in the two classes is significant. Experimental class' students have a higher ability to plan and implement problem-solving solutions than those of control class.

“…Realistic video is an interactive learning medium and has the convenience of analyzing the graphics of moving objects [50], free-falling objects [51,52], and determining moments of inertia [53]. There are several advantages of realistic video compared to online video, including being able to improve critical thinking skills [51,54], reduce the percentage of misconception [55][56][57][58][59], and increase students' graphic literacy [60]. Realistic video in MP4 format can be integrated into the e-learning module, making it easier for students to understand the phenomenon of free-fall motion.…”

Physics learning in universities utilized the Moodle-based e-learning media as an online learning platform. However, the effectiveness of remediating misconception using online media has not been widely researched. Therefore, this study was set to determine the level of misconception percentage reduction through the use of narrative feedback, the e-learning modules, and realistic video. The study was a quantitative approach with a quasi-experimental method involving 281 students who were taking basic physics courses in the Department of Physics, Chemistry, and Biology Education. The data collection used a three-tier diagnostic test based on e-learning at the beginning of the activity and after the treatment (posttest). The results of the data analysis with descriptive statistics show that the most significant treatment in reducing misconception percentage on the topic of free-fall motion was in the following order: narrative feedback, e-learning modules and realistic video. The misconception percentage reduction in the sub-concept of accelerated free- fall was effective for all types of the treatments.
