Abstract :
One of the educational developments in recent years has to do with STEM. The term STEM (Science, Technology, Engineering, and mathematics) is one approach in the learning process that is quite influential to be used today. STEM-based learning focuses students on solving problems in everyday life by combining the four fields of science: science, technology, engineering, and mathematics. The resulting device has met the validity criterion of 3.25≤ Va<4; the suggestion from validators does not change the device as a whole, but only a tiny part. The validity score obtained in each device is 3.6 for RTM (valid), 3.5 for LKM (practical), and 3.6 for THB (practical). This math learning tool also meets the criteria of practicality, and the practitioner’s advice does not change the device as a whole but only a tiny part. In addition to being valid and practical, the device also meets the criteria of effectiveness. The average student in this trial class is classified as a complete student, and the response from students is positive. Based on the test results, researchers found 16 students with 70% presentations who scored above 60.
