Effectiveness of visual programming implementation in thermodynamic experiments with the ISLE-based STEM approach model

This process involves observing, finding patterns, constructing and testing pattern plans, and using multiple representations of physical phenomena. ISLE helps students learn physics by providing a hands-on and interactive approach to learning. Visual programming is a trend in education that utilizes visual presentation to describe programs, data, structures, or dynamic behavior of complex systems. LabVIEW is a visual programming software made by National Instruments using a graphical or block diagram-based programming language. LabVIEW is applied to thermodynamic experiments to see the effectiveness of the implementation in students' learning through the ISLE-based STEM approach. The research was conducted at SMA LabSchool Unsyiah with a total of 10 students participating. The students were asked to measure the temperature with a temperature measuring device that was designed and connected to LabVIEW. The students were also asked to make programming that would display the temperature value in LabVIEW using a technology guide. This method was able to increase student interest in learning and understanding of the lessons presented, as well as develop critical thinking, creativity, and collaboration skills. The data analysis results showed that 85% of students were happy with the learning approach, 80% of students were interested in the teaching materials, 78% of students stated that the experiments were effective for learning the concepts, and 90% of students stated that they developed thinking skills. Students also showed an increase in scores on the post-test as much as 89% from the results of the pre-test. The assessment of the implementation of learning by the observer obtained a mean of 80.5%. The researchers designed the props for the topic of temperature and heat, which can be used for specific heat practicum, the energy needed to heat water, and the Black Principle. The design of the props starts with system design, schematic design of circuits, heating of electronic components, designing the LabVIEW display through visual programming, and designing the LabVIEW communication system with props through programming in the Arduino application using the C language. The data collection technique used to assess the success or failure of the ISLE-based STEM approach was carried out in three ways: using a questionnaire, interview, and observer. The questionnaire was used to determine the evaluation of the level of student satisfaction with the learning approach, while the interview was used to gather more in-depth information about the students' experiences and perceptions. The observer was used to assess the implementation of learning and provide feedback to the researchers. The results of the study showed that the ISLE-based STEM approach with visual programming implementation was effective in increasing student interest in learning, developing critical thinking, creativity, and collaboration skills, and improving student understanding of the lessons presented. The study also highlighted the importance of using visual programming in physics education, as it can make complex concepts more accessible and engaging for students.
