The grounds through which the pupils substantiate their claims are among the main elements defining the quality of their dialogic argumentation. The present research investigates the effects of the didactic elaboration of pupils’ obstacles in science on the quality of their dialogic argumentation and particularly on the improvement in the level of the grounds included in their individual comments during their discussions. Therefore, a teaching sequence on the didactic elaboration of pupils’ obstacles regarding temperature and heat was designed and implemented in primary school pupils (aged 11-12), while the pupils’ oral discourse was recorded throughout the teaching sequence. In order to record the level of the grounds included in pupils’ individual comments during the teaching sequence, the analysis of pupils’ oral discourse adopted Clark and Sampson’s classification (2008). This classification includes the four following levels of the grounds included in pupils’ individual comments: Level 0: comments without grounds, Level 1: comment with an explanation as grounds, Level 2: comment with evidence as grounds, Level 3: comment with an explanation and evidence or multiple pieces of evidence. Analysis results allowed for mapping the improvement in the levels of the grounds included in pupils’ individual comments during the teaching sequence. More specifically, it emerged that although the pupils tended to make ungrounded comments at the beginning of the teaching program, they tended to make grounded and even evidenced comments when the program was near completion. Hence, the didactic elaboration of pupils’ obstacles contributes to raising the level of the grounds included by the pupils in their comments, thus becoming a didactic strategy for improving the quality of their dialogic argumentation.
