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

Abstract

Abstract Visual programming 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 language based on graphics or block diagrams. Labview is applied to thermodynamic experiments to see the effectiveness of the implementation in students learning through the ISLE-based STEM approach. Experiments by the students were finding the specific heating value and discovering the concept of the Black principle by utilizing the Dallas 18B20 as a temperature sensor that is connected through the NodeMCU ESP8266 device and Labview software. This research was conducted at SMA LabSchool Unsyiah with a total of 10 students participated following the pandemic protocol procedure. 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, 90% of students stated that they developed thinking skills. Students get 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%.
