IoT-Based Kobela Teaching Aid for Mathematics Learning Multiplication and Division Materials for Grade II Elementary School Students

Abstract

Kotak Belajar Ajaib (Kobela) is props for elementary school math class II which can help learn to calculate multiplication and division. Based on research conducted by Sugeng Harnanto, Kobela can improve concentration, increase creativity and student learning outcomes. This tool has been tested in low-grade learning and extracurricular learning activities. The average student success in learning without using teaching aid is 54.56 (56.77%), after using teaching aid the average learning success rate reaches 90.52 (94.19%). The level of mastery learning for Basic Competencies: 3.1 Doing Multiplication of Two Numbers have increased by 37.42. In previous studies, the application of Kobela teaching aid in all learning activities was still manual-based. Potential or opportunities for development, especially for reading assessments and automatic data storage are possible to be achieved by implementing the Internet of Things (IoT). In this study, Kobela was built which implements IoT technology for reading, assessment, and recording based on learning activities. Then evaluate the system by testing the functionality of all the learning activities. From the test results, it was found that the system was running 100% by the specified function. The results of system performance testing in terms of sensor readings are on average 3 seconds with 8 Watt room lighting conditions and the average value of the assessment accuracy is 84.

Implementation of A Collaborate Learning Model Stad-Pjbl with Diorama Media to Improve Student Learning Outcomes on Eclipse Topics

“…According to Gerlach and Ely, in general, media are people, materials, or events that create conditions enabling students to acquire knowledge, skills, or attitudes (Setiawan, 2021). Thus, teachers, textbooks, and the school environment are considered media.…”

Design and Implementation of ESP32-Based IoT Devices

“…The platform is constructed from low-cost components and programmed with open-source software, making it affordable and valuable for students and researchers. Setiawan et al [ 50 ] proposed a Kobela teaching aid for teaching multiplication and division in mathematics to second-grade primary school students. The Kobela can improve students’ concentration, creativity, and learning outcomes.…”

Math Balance Aids based on Internet of Things for Arithmetic Operational Learning

“…The previously mentioned studies published the integration of IoT with games to support motor development of preschoolers. Setiawan et al build an IoT system integrated with Kobela aids at the elementary school level [27]. Kobela is an abbreviation of "Kotak Belajar Ajaib" (Magic Learning Box) which is used to support students in learning multiplication and division of numbers in mathematics.…”
