Why can semiotic representations be barriers to understanding? A study in the acid-base issue

In this paper we present the results obtained by investigating the responses of students at a first university chemistry course when faced with the same situation in the topic acid-base, expressed by different semiotic representations. The analysis of these results allowed us: 1) To assess the stude...
