Development a prototype of a didactic tool for the development of laboratory practices (HeDiLab)

The didactic tool for the development of laboratory practices - HeDiLab, aims to improve the learning of the students of Catholic Universitary Foundation "Lumen Gentium" in the study of chemical and thermodynamic phenomena, tracing as an application route the articulation of concepts and theories with phenomenology, experiments and mathematical models. Internally, it is composed of a Raspberry Pi 4 microcomputer, Arduino Mega 2560 development boards, and externally with different modules with sensors for voltage, current, light intensity, temperature, among others. As it is made from free access hardware and software elements, it allows improving the teacher / phenomenon / student interaction, through a series of experimental practices or teacher-oriented experiences in the selected subjects. To facilitate its implementation, it has a software that allows the user to interact with the tool and its different modules, as well as a learning material that through laboratory guides of chemical and thermodynamic phenomena will allow the student an improvement in apprehension of knowledge. Also, it is intended to encourage the use of free access programs, such as LibreOffice, which has characteristics very similar to the office package for commercial use. Finally, some laboratory practices that could be developed by users (student, laboratory worker and teacher) with the help of a tool are described.
