Be informed the Periodic Desk of Parts with Digital Fact—Observatory

For third-semester high school students, I designed activities for a virtual reality project focused on improving their understanding of concepts related to the internal structure of matter, such as atoms, atomic orbitals, and isotopes. We also worked on issues related to the periodic table, the properties of the elements, and their electronic configuration. We used the MelVr application, which can download for free on the students’ cell phones, then introduced the cell phone application into the virtual reality headset. For this purpose, we used the VIOTEK Specter VR Headset.

The students can enter the molecular interiors of salt, water, gas, or any other substance presented to observe its structure and understand what the teacher has just explained. Alternatively, they can first explore the molecular world and listen to the teacher’s explanation. Thus, both students and teachers achieve a symbiosis moving between the virtual and real worlds. The motivation, the faces of amazement, and the good results in the evaluations stood out in the chemistry classes in which students worked with virtual reality.

We provided the students with glasses inside which they placed their cell phones to first listen to the explanation of the topic. As they entered the substances virtually, they learned about the internal structure of matter through the stimulation of all their senses. Once introduced the topic through virtual reality, the teaching-learning process was much simpler because the virtual interactions with the internal structure helped them understand abstract topics and concepts more quickly.

Incorporating this technology was carried out in two experimental groups and a control group, the latter receiving classes traditionally, using videos and the blackboard to explain the class topics. The results were significantly encouraging; the experimental groups had higher evaluation averages than the control group in most activities. Notably, the most significant difference was the students’ understanding of the concepts: the experimental groups made much more detailed explanations of the internal structure of matter than the control group.

Finally, in the student survey conducted to know their motivation in their learning process, the experimental groups expressed their enjoyment in learning chemistry differently in a fun way through this technology.

Virtual reality applications for learning chemistry

Several virtual reality applications for learning are available, requiring special glasses to maximize the brain’s stimuli and thus improve the learning process. Ramirez and Bueno (2020) used an immersive environment through a virtual laboratory application for organic chemistry, concluding that their students improved their understanding of complex topics. They also observed that the skills and knowledge acquired were enhanced using virtual environments. The sensations experienced by students interacting through these tools helped them learn chemistry differently. Many applications offered in the market make it possible to find a number of them suitable for most organic and inorganic chemistry topics.

Some virtual reality applications for learning chemistry are excessively costly, but others, such as Mel Vrwhich I used with my students, are accessible for free. This application allows observing the atomic structures of the periodic table elements, the arrangement of their electrons, and their orbitals; thus, we could delve into the subject of electronic configuration without neglecting the characteristics that predict their properties. Likewise, Maksimenko et al. (2021) used this same application with first-year university students to connect macroscopic, tangible common substances with the microscopic world of their internal structure, resulting in better learning experiences. They concluded that using the MelVr application improved learning abstract concepts related to atomic structure and the periodic table.

Using immersive technologies has resulted in better learning outcomes and increased student motivation, highlighting that more teachers should use these technologies in their classrooms. Several options do not require significant investments. Others can be feasible thanks to the support of the NOVUS fund that allows us to implement new strategies to improve teaching processes.

I invite you to explore the use of virtual reality in your courses and share your experiences and learning through the Observatory of the Institute for the Future of Education of Tec de Monterrey.
