When learning a new math concept, should learners be first taught the concept and its associated procedures and then solve problems, or solve problems first even if it leads to failure and then be taught the concept and the procedures? Two randomized‐controlled studies found that both methods lead to high levels of procedural knowledge. However, students who engaged in problem solving before being taught demonstrated significantly greater conceptual understanding and ability to transfer to novel problems than those who were taught first. The second study further showed that when given an opportunity to learn from the failed problem‐solving attempts of their peers, students outperformed those who were taught first, but not those who engaged in problem solving first. Process findings showed that the number of student‐generated solutions significantly predicted learning outcomes. These results challenge the conventional practice of direct instruction to teach new math concepts and procedures, and propose the possibility of learning from one's own failed problem‐solving attempts or those of others before receiving instruction as alternatives for better math learning.  相似文献

ObjectivesThe purpose of this study was to examine career experiences of UK-based female youth soccer players from a holistic perspective with a view to producing a grounded theory of factors contributing to career/talent development and transitions in UK youth female soccer.MethodologyA Grounded Theory methodology (Corbin & Strauss, 2008) was used. Negative case (Denzin, 1989) former female soccer players (N = 13), their best friend (N = 13), soccer coaches (N = 4), and teachers (N = 8) took part in semi-structured interviews about factors associated with talent development and career transitions in female youth soccer.ResultsMultiple social agents (players, team-mates, peers, teachers, parents and siblings) need to optimally interact to ensure that an optimal talent development and learning environment is created. This will provide a supportive holistic talent development environment, lead to adaptive player-level changes, and a greater chance of successful athletic and dual career development.ConclusionsThis study presents a rich understanding of the dual careers of players who did not make it in female soccer. By considering their perspectives alongside of a range of important social agents, we have been able to construct a substantive grounded theory of factors contributing to career/talent development and transitions in UK youth female soccer. As a result, these findings may contribute to policy and practice development in UK female youth soccer.  相似文献

ObjectiveThere is limited understanding of how sport motivation is associated with deliberate practice in youth team sport athletes. Therefore, the aim of this study was to examine prospective associations between intrinsic motivation and individual deliberate practice in specializing team sport athletes.DesignLongitudinal.MethodEstonian adolescent team sport athletes (N = 163; Mage – 13.6 years at the beginning of study) completed the Sport Motivation Scale and training diary across a 12-month period.ResultsBoth individual deliberate practice and intrinsic motivation increased over the 1-year period. Greater baseline intrinsic motivation predicted subsequent individual deliberate practice and greater initial individual deliberate practice predicted greater subsequent intrinsic motivation. The bidirectional relationship between athletes intrinsic motivation and individual deliberate practice were replicated across both time lags.ConclusionThe findings have significant implications for the importance placed on intrinsic motivation as a means of increasing of individual deliberate practice as well being an important outcome variable in specializing team sport athletes.  相似文献

Eating attitudes are predictive of disordered eating, which can be quite prevalent among collegiate athletes. The present study tested if disordered eating attitudes and the sex of collegiate athletes are related to “self-controlled food choice” for four food types: a dessert, fried food, fruit, and vegetable. In total, 102 athletes completed a disordered eating attitudes assessment and a delay discounting task. For the delay discounting task, athletes chose between one large delayed reward and one successively smaller immediate reward for four food types, and indifference points were computed with lower indifference points indicating greater self-controlled food choice. In this study female athletes showed greater self-controlled food choice for all three tempting food types (dessert, fried food, and fruit), but not the control food type (vegetable). For males, results were moderated by their level of disordered eating attitudes. Overall, these data show that “self-controlled food choice,” measured using a delay discounting task, is a key factor related to sex differences in disordered eating attitudes among college athletes.  相似文献

This paper addresses the extent to which quotidian cognition is like scientific inference by focusing on Jerry Fodor's famous analogy. I specifically consider and rebut a recent attempt made by Tim Fuller and Richard Samuels to deny the usefulness of Fodor's analogy. In so doing, I reveal some subtleties of Fodor's arguments overlooked by Fuller and Samuels and others. Recognizing these subtleties provides a richer appreciation of the analogy, allowing us to gain better traction on the issue concerning the extent to which everyday cognition is like scientific inference. In the end, I propose that quotidian cognition is indeed like scientific inference, but not precisely in the way Fodor claims it is.  相似文献

A new methodology for developing theories of action has recently emerged which provides means for formally evaluating the correctness of such theories. Yet, for a theory of action to qualify as a solution to the frame problem, not only does it need to produce correct inferences, but moreover, it needs to derive these inferences from a concise representation of the domain at hand. The new methodology however offers no means for assessing conciseness. Such a formal account of conciseness is developed in this paper. Combined with the existing criterion for correctness, our account of conciseness offers a framework where proposed solutions to the frame problem can be formally evaluated.  相似文献

Retirement from sport has been associated with elevated levels of depression, anxiety and/or body dissatisfaction among athletes. Psychosocial dimensions, such as having reached sport goals and planned for life after sport, may affect how retired athletes’ respond psychologically. Thus, the primary aim of this study was to examine the association between psychosocial aspects of sports transition with body satisfaction, depressive symptoms and, life satisfaction among 217 female former NCAA athletes. Through hierarchical regression analyses, and after controlling for BMI and years since retirement, we determined that athletes who believed they had achieved their sport goals, developed a new life focus after their sport career, had focused on life areas other than just sport while competing, and remained involved in their sport in different ways after retirement reported being more highly satisfied with their lives and their bodies and experiencing fewer depressive symptoms; variance accounted for ranged from 24% to 28% across these outcomes. Athletes’ perceptions of what has occurred in their lives while transitioning from sport may have longstanding effects on their psychological well-being in retirement. Longitudinal methodologies are needed to determine the temporal influence of these psychosocial dimensions.  相似文献

Reducing concussion risks in athletes depends on self‐reporting. Often, athletes decide whether to report concussions or continue playing and risk serious health consequences. Fuzzy‐trace theory (FTT) predicts that reliance on gisty, categorical representations of risky decisions, not amounts of risk/reward, encourages risk avoidance and application of bottom‐line values, or gist principles, thus promoting healthy decisions. Applying FTT, we test whether intentions to report are predicted by gist‐based thinking about risks and values. High school and college students (N = 1,366) were assessed for concussion knowledge, social pressures to not report (by coaches/parents/teammates), categorical gist‐based thinking, endorsement of gist principles expressing values, and intentions to report. As expected, the older group scored higher on gist measures. For young adults, categorical thinking, and gist principles predicted intentions, controlling for sex, knowledge, and social pressures. For adolescents, categorical thinking again predicted intentions. For both age groups, adding FTT's predictors accounted for significantly more variance than baseline models.  相似文献

Multiple theories of problem‐solving hypothesize that there are distinct qualitative phases exhibited during effective problem‐solving. However, limited research has attempted to identify when transitions between phases occur. We integrate theory on collaborative problem‐solving (CPS) with dynamical systems theory suggesting that when a system is undergoing a phase transition it should exhibit a peak in entropy and that entropy levels should also relate to team performance. Communications from 40 teams that collaborated on a complex problem were coded for occurrence of problem‐solving processes. We applied a sliding window entropy technique to each team's communications and specified criteria for (a) identifying data points that qualify as peaks and (b) determining which peaks were robust. We used multilevel modeling, and provide a qualitative example, to evaluate whether phases exhibit distinct distributions of communication processes. We also tested whether there was a relationship between entropy values at transition points and CPS performance. We found that a proportion of entropy peaks was robust and that the relative occurrence of communication codes varied significantly across phases. Peaks in entropy thus corresponded to qualitative shifts in teams’ CPS communications, providing empirical evidence that teams exhibit phase transitions during CPS. Also, lower average levels of entropy at the phase transition points predicted better CPS performance. We specify future directions to improve understanding of phase transitions during CPS, and collaborative cognition, more broadly.  相似文献
