We examined how mushroom experts organize and process their knowledge, compared with novices, and which types of arguments they use to process information. Mushroom experts and novices carried out an identification/memorization task, a free recall task, and a matching task. Results showed that experts performed better than novices on all three…

Proportional reasoning is a key topic both at school and in everyday life. However, students are often misled by their preconceptions regarding proportions. Our hypothesis is that these limitations can be mitigated by working on alternative ways of categorizing situations that enable more adequate inferences. Multiple categorization triggers…

To grasp how individuals and groups perceive social objects of their environment, word association tasks enable the cognitions associated with a given object to be collected. However, the lack of information regarding the meaning of these responses implies interpretation and subjectivity in their analysis. To reduce this subjectivity, this…

The present study looks into the largely unexplored territory of the cognitive underpinnings of semantic approximations in child language. The analysis of a corpus of 233 semantic approximations produced by 101 monolingual French-speaking children from 1;8 to 4;2 years of age leads to a classification of a significant number of them as instances…

How does cognitive control change with age, and what are the processes underlying these changes? This question has been extensively studied using versions of the task-switching paradigm, which allow participants to actively prepare for the upcoming task (Kray, Eber, & Karbach, 2008). Little is known, however, about age-related changes in this…

This study examined the within-subject stability of 150 participants who performed both a sorting task and a property-generation task over multiple sessions, focusing on three concrete concept categories (food, animals and bathroom products). We hypothesized that (1) the within-subject stability would be higher in the sorting task than in the…

Focusing on one teacher's categorization of students'"searching" behavior, describes a case study drawn from ethnographic investigations of classrooms in France and offers a model of the interpretative process. (RH)

The 7th International Conference on Education Data Mining held on July 4th-7th, 2014, at the Institute of Education, London, UK is the leading international forum for high-quality research that mines large data sets in order to answer educational research questions that shed light on the learning process. These data sets may come from the traces…
