Children’s notions of the malleability of their academic competencies

This study set out to examine children’s notions of the malleability of their academic competencies and the relations of these notions to the child’s grade-level and gender and the parent’s educational level. In interviews of a total of 103 boys and girls of the third and the sixth grade, children of academically and vocationally educated parents were asked to rate their potential for improving their competencies in mathematics and Finnish. The children were asked to use intrapersonal and normative criteria in their ratings. The ratings were found to form distinct domains of the notions of malleability, as they did not correlate with each other. The children’s ratings of their current competencies, i.e. their academic self-concepts, turned out to be related to their normative ratings of the malleability of their competencies. The findings further suggested that the children’s notions of the malleability of their academic competencies became more pessimistic in the course of their school years.

Belief, assertion and Moore’s Paradox

In this article I argue that two received accounts of belief and assertion cannot both be correct, because they entail mutually contradictory claims about Moore’s Paradox. The two accounts in question are, first, the Action Theory of Belief (ATB), the functionalist view that belief must be manifested in dispositions to act, and second, the Belief Account of Assertion (BAA), the Gricean view that an asserter must present himself as believing what he asserts. It is generally accepted also that Moorean assertions are absurd, and that BAA explains why they are. I shall argue that ATB implies that some Moorean assertions are, in some fairly ordinary contexts, well justified. Thus BAA and ATB are mutually inconsistent. In the concluding section I explore three possible ways of responding to the dilemma, and what implications they have for the nature of the constitutive relationships linking belief, assent and behavioural dispositions.

Contrôle d’animations multimédias par des enfants de dix à 11 ans : quel effet des dispositifs de contrôle ?

The present study aims at exploring the effect of user control on learning from technical animations. First, the concept of user controllability is defined and possible reasons for the divergent findings concerning its effectiveness in supporting learning are considered. Second, an empirical study is reported, in which young learners studied the operation of gear systems from animated instruction involving different levels of user control. Finally, results of the study are discussed and related to processing constraints that may influence the educational effectiveness of user controllable animations.     

On Similarity Coefficients for 2×2 Tables and Correction for Chance

This paper studies correction for chance in coefficients that are linear functions of the observed proportion of agreement. The paper unifies and extends various results on correction for chance in the literature. A specific class of coefficients is used to illustrate the results derived in this paper. Coefficients in this class, e.g. the simple matching coefficient and the Dice/Sørenson coefficient, become equivalent after correction for chance, irrespective of what expectation is used. The coefficients become either Cohen’s kappa, Scott’s pi, Mak’s rho, Goodman and Kruskal’s lambda, or Hamann’s eta, depending on what expectation is considered appropriate. Both a multicategorical generalization and a multivariate generalization are discussed.     

Issues Involving Informed Consent for Research Participants with Alzheimer’s Disease

Alzheimer’s disease is the most common form of dementia which is estimated to impact 350,000 people over 65 years of age in Canada. The lack of effective treatment and the growing number of people who are expected to be diagnosed with Alzheimer’s disease in the near future are compelling reasons why continued research is in this area is necessary. With additional research, there needs to be greater recognition of the complexity of seeking ongoing informed consent from those with Alzheimer’s disease. This complexity is because the impairment of memory and cognitive ability does not diminish in a linear manner, but rather fluctuates between periods of impairment and relatively normal cognitive lucidness. There is limited discussion in the guidelines of those progressing from early stages of Alzheimer’s disease who have intermittent cognitive function. Guidelines to research and Research Ethics Boards require further development to facilitate researcher including those with Alzheimer’s disease while protecting this growing pool of potential participants.     

Bochenski on Property Identity and the Refutation of Universals

An argument against multiply instantiable universals is considered in neglected essays by Stanislaw Lesniewski and I.M. Bochenski. Bochenski further applies Lesniewski’s refutation of universals by maintaining that identity principles for individuals must be different than property identity principles. Lesniewski’s argument is formalized for purposes of exact criticism, and shown to involve both a hidden vicious circularity in the form of impredicative definitions and explicit self-defeating consequences. Syntactical restrictions on Leibnizian indiscernibility of identicals are recommended to forestall Lesniewski’s paradox.     

Taxicab Correspondence Analysis

Taxicab correspondence analysis is based on the taxicab singular value decomposition of a contingency table, and it shares some similar properties with correspondence analysis. It is more robust than the ordinary correspondence analysis, because it gives uniform weights to all the points. The visual map constructed by taxicab correspondence analysis has a larger sweep and clearer perspective than the map obtained by correspondence analysis. Two examples are provided. This research was financed by the Natural Sciences and Engineering Research Council of Canada. The author thanks Serge Vienneau for his help regarding the graphical displays, and also thanks the editor, associate editor, and two reviewers for their constructive comments.     

Functional reduction and emergence in the physical sciences

Kim’s model of ‘functional reduction’ of properties is shown to fail in a class of cases from physics involving properties at different spatial levels. The diagnosis of this failure leads to a non-reductive account of the relation of micro and macro properties.
