Summary/Abstract: Understanding the submicro level is difficult for students, requiring a deeper chemistry knowledge. In this study, 32 students performed a teaching-learning sequence in order to understand the submicro level of two electrochemical reactions. Among the thirty-two students, eight of them were analyzed, using the records and the transcriptions of the filming. The results indicated that students who used more chemical terms were able to achieve better understandings of the submicro level, since that talking more, in this case, showed no relation to learning.
