Analysis of issues of Physics distractors in large-scale tests

Abstract

Generally, the school community depreciates large-scale tests because these are considered summative, in which the results observed do not return to the candidates, there is no feedback. In this work, we will show some analysis on the results of problem-solving strategies researches. In order to understand the greatest difficulties among students concerning the knowledge of Physics that are measured by large-scale tests, we used as an example the Enem (Exame Nacional do Ensino Médio). In this regard, we analyzed the questions of Physics classified in the object of knowledge "movement, balance and discovery of the laws of physics" for the years 2009-2012. Our results show that some students use non-scientific concepts to solve the questions, have difficulties in transposing the problem to another context, use intuitive reasoning and symbolic forms for questions that require a mathematical approach to be solved. In presenting these discussions, we aim to provide an analysis on the questions with qualitative and quantitative indicators of the main difficulties presented by the students in solving tests as Enem.
