Simulação e modelagem computacionais no auxílio à aprendizagem significativa de conceitos básicos de eletricidade: parte I - circuitos elétricos simples

In this paper we analyze different students conceptions and reasonings regarding basic concepts involved in simple electric circuits, that become obstacles for the learning, and present a product of a research work, that consists in a set of computational modeling and simulation activities, developed with the software Modellus, taking into account such difficulties to help students to surpass them.

Simulação e modelagem computacionais no auxílio à aprendizagem significativa de conceitos básicos de eletricidade. Parte II: circuitos RLC

In this paper we analyze the behavior of electromagnetic energy in RLC circuits, discussing the main students difficulties on basic concepts involved and presenting two products originated in a research work: i) a set of computational modelling and simulation activities, developed with the software Modellus, taking into account such difficulties to help students to surpass them and ii) a test about the understanding of physics concepts involved in RLC circuits.

Uso da plataforma Arduino e do software PLX-DAQ para construção de gráficos de movimento em tempo real

This paper presents an educational tool developed using the Arduino platform with a position sensor and the PLX-DAQ software, which was used in developing a learning experiment suitable for teaching graphics kinematics that was applied to the masters work. The aim was to overcome learning difficulties faced by students of basic education in the construction and interpretation of graphs, like position versus time in the Cartesian coordinate system. We present a detailed description of instrumentation and some results of an implementation carried out with two groups of 1st year of high school, a State school in the city of Candiota / RS. In the implementation, we identified an increase in student performance, which demonstrated certain difficulties in the analysis and interpretation of motion graphics at the beginning of the activity; however, they developed skills in the course of tasks, achieving both qualitative and quantitative results (statistically significant). The students were able to interpret and reproduce motion graphics in real time from the instrumentation proposed in this work.
