The Development of Thermodynamics Law Experiment Media Based on IoT: Laboratory Activities Through Science Problem Solving for Gifted Young Scientists

Abstract

In this research, thermodynamics law experiment media based on IoT was developed and tested. The purpose was to assess the effectiveness of the IoT-based thermodynamic law experiment media through a problem-based learning approach and laboratory activities using science problem solving for talented young scientists. This research was conducted at SMA 2 Batang. This study using the ADDIE approach model. The development steps are: (1) analyzing curriculum requirements and demands in 2013, (2) designing and manufacturing, (3) developing media, (4) limited through small-scale tests, expert testing, tested on professional physics teachers and student grade XI sciences, (5) evaluated to get feedback in the form of comments and suggestions. This media is equipped with an LCD display to read of temperature, electric current, and electrical voltage in real-time which is integrated with the the Thingspeak application on every student’s android phone. This media is easily assembled, based on digital, equipped with manuals and student worksheets. The validation results from the media experts 90.20% (Very Good), the results of the validation from the material experts 91.50% (Very Good), and the results of the physics teacher’s responses covering all aspects of the material and multimedia 93.00% (Very Good). The results of the validation show that thermodynamics law experiment media based on IoT is appropriate to be used as a media for learning activities in the thermodynamics law material laboratory.

“…Pengembangan media bahan ajar seperti e-modul [10], aplikasi android [11], blended learning [12], dan eksperimen [13] menggunakan model pembelajaran 4D Thiagarajan dan ADDIE. Tetapi pada penelitian ini langkah pengembangan yang dilakukan ini diadaptasi dari Boimau (2020) [14].…”

How to Manage an Effective Laboratory for Science Learning in Schools?

“…The above study results reveal that the role of the practicum is significant in science learning. Rustaman (2010) suggests four reasons for the importance of practicum activities, namely: (1) it can generate learning motivation, (2) it can develop science process skills (Saputra et al 2021)), (3) become a vehicle for learning with a scientific approach (Liana et al 2020), and (4) strengthen students' understanding through discovery (Haryadi & Pujiasturi 2019). Kohnle et al (2012) revealed that students could understand the concepts and processes with experimental activities.…”

The Level of Higher-Order Thinking Skills in Basic Physics Practicum

“…Physics practicum activities in the laboratory are absolutely carried out as a process of forming student competencies that aim to improve the process of understanding physics concepts. Practical activities are able to train students' basic research skills such as skills in using measuring instruments, skills in choosing appropriate measurement data collection methods, skills in processing obtained measurement data, skills in analyzing data from practicum results, skills in drawing conclusions from practicum results, and skills in communicating practical results [12][13][14].…”
