Piecing Together the Puzzle of Pictorial Representation: How Jigsaw Puzzles Index Metacognitive Development

Jigsaw puzzles are ubiquitous developmental toys in Western societies, used here to examine the development of metarepresentation. For jigsaw puzzles this entails understanding that individual pieces, when assembled, produce a picture. In Experiment 1, 3- to 5-year-olds (N = 117) completed jigsaw puzzles that were normal, had no picture, or comprised noninterlocking rectangular pieces. Pictorial puzzle completion was associated with mental and graphical metarepresentational task performance. Guide pictures of completed pictorial puzzles were not useful. In Experiment 2, 3- to 4-year-olds (N = 52) completed a simplified task, to choose the correct final piece. Guide-use associated with age and specifically graphical metarepresentation performance. We conclude that the pragmatically natural measure of jigsaw puzzle completion ability demonstrates general and pictorial metarepresentational development at 4 years.  相似文献

T. rex,the Crater of Doom,and the Nature of Scientific Discovery     

Lawson  Anton E 《Science & Education》2004,13(3):155-177

Working from the 1970s to the early 1990s, Walter Alvarez and his research teamsought the cause of the mass extinction that claimed the dinosaurs 65 million years ago. The present paper discusses thatresearch in terms of eight puzzling observations, eight episodes of hypothetico-predictive reasoning, enumerative induction,and Jung's interrogative theory of scientific discovery. The Alvarez case history paints scientific discovery as a process in whichcausal questions are raised and answered through the creative use of analogical reasoning followed by an equally creative process ofhypothesis testing in which predicted and observed results are compared. According to this account, puzzling observations, causalhypotheses, and imagined tests drive investigations and the search for evidence. Two implications follow. The firstconcerns the education of new scientists and science education researchers and the need to more clearlydifferentiate hypotheses from predictions in the research process. The second concerns standard science classroom instruction that shouldmore frequently engage students in open inquiries that raise causal questions and encourage the generation of alternative causalhypotheses, which can then be explicitly tested in ahypothetico-predictive fashion.  相似文献   

Purposes of education for young people with severe learning difficulties: exploring a vocational teaching resource – ‘A stepping stone to…’ what?     

Alison Black  Hazel Lawson 《Cambridge Journal of Education》2017,47(2):207-226

This article examines the purposes of education with a particular focus on young people with severe learning difficulties (SLD). The topic is explored with reference to a specific case, whereby some of the key findings of an evaluation of the first year of ‘The Greenside Studio’, an English special school’s vocational teaching resource for young people with SLD, are presented. A conceptualisation of different ‘sides’ to the Studio is discussed in relation to the purposes of education for these learners in which the view of vocational learning as a stepping stone to paid employment and independence is presented as problematic. With a broader interpretation of vocational education this stepping stone is reconfigured as a bridge to life after school, whatever form that takes. It is argued, however, that the nature of this life must be viewed aspirationally.  相似文献

Is Piaget's epistemic subject dead?     

Anton E. Lawson 《科学教学研究杂志》1991,28(7):581-591

Niaz (1990) presents arguments in favor of the retention of Piaget's epistemic subject as a theoretical construct to guide research and practice in science education and psychology. The intent of this article is to point out the weaknesses of those arguments and to suggest that the weight of evidence argues against the existence of the logical thinker postulated by Piaget. Therefore, contrary to Niaz's conclusion that the acceptance of Piaget's epistemic subject will facilitate the development of cognitive theories with greater explanatory power, the conclusion is reached that Piaget's epistemic subject is dead and that continued acceptance of this aspect of Piagetian theory would be counterproductive.  相似文献   

The Physical Education System as a Consequential Social Determinant     

Hal A. Lawson 《Quest (Human Kinetics)》2020,72(1):72-84

ABSTRACT

Employing the ideal type of “The Physical Education System,” in this analysis I explore the import of systems frameworks for new institutional designs which hold promise for better outcomes. The inherited idea of a system is restricted to the relationship between teacher education and school programs. It draws on the developmental trajectory of the specialized field of study which pre-dated Kinesiology, and it conforms to the industrial age school, particularly its assumptions regarding standardized curricula, teachers’ roles, student classification, and cultural assimilation. When this inherited framework reigns, other key systems components (e.g., public policy, influential peer/family/community ecologies) get short shrift, important “outcome chains” are not addressed, and both Kinesiology’s and Public Health’s contributions are constrained. Once the inherited physical education system is recognized as a consequential social determinant of pediatric health and well-being, needs and opportunities for redesign become apparent.  相似文献

The acquisition of basic quantitative reasoning skills during adolescence: Learning or development?     

Anton E. Lawson  Jonathan M. Bealer 《科学教学研究杂志》1984,21(4):417-423

Five items requiring use of proportional, probabilistic, and correlational reasoning were administered to students in grades 6, 8, 10, and 12. Proportions are taught in the school district in grades 7 and 8, probability in grade 10, and correlations are not taught. Based on the hypothesis that successful performance is due to classroom instruction, improvements on the proportions item were predicted between grades 6 and 10 and improvements on the probability items were predicted between grades 10 and 12. Actual gradewise improvements did not correspond well with predictions. Yet performance did correlate significantly with enrollment in classes such as chemistry, physics, and trigonometry. It is argued that successful qualitative reasoning arises as a consequence of the process of equilibration, and influences one's selection of course work. Specific instruction may initiate the equilibration process.  相似文献
