With this purpose, it was decided to propose and validate a simulation in Virtual Reality (VR) of oscillatory movements to help solve problems in high school. The first step of this research was to study problem-solving pedagogical theories that solidly fostered the project and then research accessible and easily manipulated VR environment development tools. With the theoretical foundation consolidated and the software defined, we selected the branch and branch of the physical phenomenon in which we developed the virtual simulation, which aims to be used in high school physics classes. The final product was evaluated and shows signs of being a tool that assists teachers and students regarding the visualization and understanding of a physical phenomenon, and they have the opportunity to interact with the phenomenon.

We intended to enrich learning about heat propagation in order to understand the relationship between temperature, heat, thermal energy, heat flow and thermal balance. Considering this, we analyzed how the practical classes of Physics with the experimental device assembled from recyclable materials would contribute to the understanding and learning of students. We could observe that with the aid of experimental activity, the teaching process could make the learning process more efficient and enjoyable, thus contributing to improve the Physics teaching since it was observed that with the application of experiment in the classroom, students were more motivated, interested and curious about the subject. Overall, the survey results showed that when we used experiments in classroom as an educational tool, there was a significant evolution in the learning process because students showed a development in learning. We believe this research may help Physics teaching as one more pedagogical purpose centered on experimental practice with the need to redeem increasingly critical knowledge and reflections on the content addressed in class in the students. It is also important that the teacher can reflect upon how the student can understand and learn the concepts so that one can investigate, plan and develop strategies and ways to achieve significant learning. Thus, we conclude that students developed skills and competencies in content which involved the concepts related to heat spread. Regarding the steps of the application of the research, the students advanced and learned significantly.

The experiment proposed in the Dissertation is based on the prototype device produced by Pasco, with the record (economy resonance tube wa-9495), an industrialized version of easy handling. The alternative experiment consists of a tube with one open end and the other closed, in a mechanism that allows the variation of tube length by means of a piston inside the tube, allowing to identify the wavelength of each mode of vibration, perceiving concepts characteristic element of wave, such as wavelength and frequency, and also, to explore phenomena such as resonance, compression and rarefaction.
