Proposta de atividade de verificação de aprendizagem sobre associação de lâmpadas com uso do simulador PhET.

Abstract

This paper aims to verify students' learning regarding the content of lamp associations using the PhET simulator as a didactic resource and the application of an activity script, aimed at high school students in general. However, it was carried out with students from IFRN Campus Santa Cruz in the integrated mode, using the PhET platform building kit from the University of Colorado PhET platform. Founded in 2002 by Nobel laureate Carl Wieman, the PhET (Physics Educational Technology) project creates interactive simulations of physics, chemistry, mathematics, earth science and biology. These are essentially digital resources in different formats: audio, video, animation and computer simulation with specific characteristics in the teaching and learning process. Interactive simulations are today an efficient mechanism to present scientific concepts and contribute to make teachers and students autonomous in the teaching and learning process. The work was developed in a sequence of 4 questionnaires, where in each of them a tutorial was made available. assemble the proposed simulations. In the first stage of the activity the student built a circuit of a series association with 3 lamps; In the second stage, he built a circuit of an association in parallel with 3 lamps; In the third and fourth stages of the activity the student verified what are the parameters that determine the brightness of the lamps from the analysis of quantities such as electrical voltage, electrical current, electrical resistance and dissipated power. These sequences of activities in the simulator should develop in the student a better understanding about the content that was addressed regarding the association of lamps. It is intended to use this activity as a classroom teaching strategy. The purpose of the learning verification activity using the PhET simulator was precisely to make the students more interested in the content and motivation to search the information that was required in the questionnaires by constructing the proposed simulations that can be seen in topic 8. of the annexes. The results obtained in the pre-class diagnostic activity and the application of the Learning showed that the proposal presented here is efficient from the point of view of Physics Teaching with emphasis on the topic of electricity, because most students demonstrated understanding about the knowledge regarding the types of lamp association. The work developed here is expected to contribute to the teaching of physics presenting itself as a research alternative to teachers and students in the area, providing subsidies for the discussion around the use of simulators in the classroom.
