The current paper provides a dialectical interpretation of the argumentation-based judgment aggregation operators of Caminada and Pigozzi. In particular, we define discussion-based proof procedures for the foundational concepts of down-admissible and up-complete. We then show how these proof procedures can be used as the basis of dialectical proof procedures for the sceptical, credulous and sup...

Invention activities are Productive Failure activities in which students attempt to invent methods that capture deep properties of given data before being taught expert solutions. The current study evaluates the effect of scaffolding on the invention processes and outcomes, given that students are not expected to succeed in their inquiry and that all students receive subsequent instruction. Two...

Disposition theory proposes that appeal is a function of the dispositions viewers hold towards characters, which are in turn driven by viewer perceptions of character morality and outcomes experienced by characters.

The current study examines the extent to which the whole number bias, especially whole number ordering, can interfere with adult understandings of fractions. Using the framework theory approach to conceptual change as outlined by Vosniadou (2007; Vosniadou, Vamvakoussi & Skopeliti, 2008), this study supports the idea that initial concepts formed in childhood can have lasting effects into adulth...
