Prototipo electrónico para el desarrollo de prácticas experimentales de física en el bachillerato

Abstract

In chapter one, the problem and the possible solutions are diagnosed; in addition, the general objective, the specific objectives, the hypothesis, the thesis contributions that are: theoretical - methodological contribution, the practical contribution, the scientific novelty; and the state of the art, are in it. The second chapter is about the theoretical foundation where the fundamental bases referring to physics laboratories are investigated, such bases are their use, basic laboratory practices and the stages to carry out laboratory practices; An analysis is also carried out on: software in teaching - learning, educational software, educational programs characteristics, types of educational software, among others; In addition, electronic software is investigated: Arduino and LabVIEW, sensors, motor, conveyor belt, module to control the direction and speed of the motor, these will be used in the electronic prototype construction for physics practices. The third chapter refers to the materials or elements basic requirements which are part of the physics laboratory; an investigation on the diagnosis of the Azogues schools physics laboratories is made through surveys in six different schools which were selected strategically, for this survey the first year high school students were selected, the objective of this is to know the physics laboratories current situations in different schools, the total number of students surveyed is 192. The fourth chapter aims to the electronic prototype design and construction, which has been developed in five parts. The first one is the model design, the second part is about the model design, the model was made in wood for its easy handling, the third part is the software design, it is subdivided in two sections, the first one is LabVIEW the programming and the second is Arduino programming; the fourth part is about the flow diagrams for each practice, and finally there is the practices manual where each of them is specified: uniform rectilinear movement, uniformly varied rectilinear motion, kinetic energy, work and power. In the fifth chapter a results analysis is made to expose them by means of conclusions and recommendations, in order to meet this objective, the first and second year students of the Catholic University Educational Unit were surveyed after having completed the internship.
