In this essay, I respond to commentators on my article on the Active Concerned Citizenship and Ethical Leadership (ACCEL) model for understanding giftedness. I cover a number of topics that arose in or out of the commentaries, in particular, systems inertia; toxic leadership; teaching for creativity; flight from reality; the role of science, technology, engineering, and mathematics (STEM) in teaching for wisdom; the developmental nature of giftedness; making a positive, meaningful, and enduring difference; IQ as a diagnostic tool rather than as a gatekeeper; meeting the needs of marginalized young people; teacher education; and retrospective studies. I conclude that the differences among all of us in this symposium are small and that we all agree that a model like ACCEL—whatever its exact terms—is needed to move the field of giftedness beyond a preoccupation with abilities, narrowly defined.  相似文献

The use of dietary supplements is widespread in sport and most athletes competing at the highest level of competition use some form of dietary supplementation. Many of these supplements confer no performance or health benefit, and some may actually be detrimental to both performance and health when taken in high doses for prolonged periods. Some supplements contain excessive doses of potentially toxic ingredients, while others do not contain significant amounts of the ingredients listed on the label. There is also now evidence that some of the apparently legitimate dietary supplements on sale contain ingredients that are not declared on the label but that are prohibited by the doping regulations of the International Olympic Committee and of the World Anti-Doping Agency. Contaminants that have been identified include a variety of anabolic androgenic steroids (including testosterone and nandrolone as well as the pro-hormones of these compounds), ephedrine and caffeine. This contamination may in most cases be the result of poor manufacturing practice, but there is some evidence of deliberate adulteration of products. The principle of strict liability that applies in sport means that innocent ingestion of prohibited substances is not an acceptable excuse, and athletes testing positive are liable to penalties. Although it is undoubtedly the case that some athletes are guilty of deliberate cheating, some positive tests are likely to be the result of inadvertent ingestion of prohibited substances present in otherwise innocuous dietary supplements.  相似文献

This paper examines discussions of Generation Y within higher education discourse, arguing the sector's use of the term to describe students is misguided for three reasons. First, portraying students as belonging to Generation Y homogenises people undertaking higher education as young, middle-class and technologically literate. Second, speaking of Generation Y students allows constructivism to be reinvented as a ‘new’ learning and teaching philosophy. Third, the Generation Y university student has become a central figure in concerns about technology's role in learning and teaching. While the notion of the ‘Generation Y student’ creates the illusion that higher education institutions understand their constituents, ultimately, it is of little value in explaining young adults' educational experiences.  相似文献

Creativity varies across time and place. With regard to variations across time, age‐related changes in the quantity, quality, and form of creative performance are examined. These changes are traced to a combination of cognitive, conative, and environmental variables. With regard to variations across place, the effect of cultural environment on creativity is examined. Culture is shown to influence the definition and expression of creativity, channeling creativity into certain task domains or social groups. The quantity of creative activity can be further affected by cultural features such as the value placed on conformity. Life span and cross‐cultural perspectives on creativity, it is argued, are integral to a comprehensive understanding of creativity.  相似文献

The purpose was to compare the performance of normal and educable mentally retarded children on pattern recognition tasks. Pattern recognition was assessed by the administration of 96 pattern tasks which measured the ability of children to find: (a) duplicate patterns and same elements as presented in model pattern sequences; (b) opposite patterns and same elements as presented in model pattern sequences; and (c) duplicate patterns but different elements than presented in model pattern sequences. The normal and mentally retarded children were matched on mental age derived from individual and group intelligence tests. Results indicated significant differences in performance measures between groups and various pattern tasks. The data support the suppositions that: (a) mentally retarded children and normal children show the same type of progression through the hierarchical arrangement of pattern tasks; and (b) mentally retarded children show a slower progression through the hierarchy than normal children when matched on mental age. Educational implications from this study are discussed.  相似文献

This article describes a theory of factors which affect intellectual performance. Many current programs and approaches to improving thinking skills tend to be overly narrow, often ignoring the affective domain and features of the environmental context. The BACEIS model is a comprehensive theory of internal and external factors affecting the development, retention and transfer of thinking and learning skills. The internal supersystem consists of cognitive and affective subsystems which interact with each other and with the external supersystem and its components. The external supersystem encompasses academic and non-academic subsystems. Three uses of the theory are discussed: for instructional design, to guide research, and to critique existing approaches.  相似文献

One important aspect of teacher effectiveness, of course, is formal knowledge of one or more academic disciplines. But another aspect of teacher effectiveness may be informal, or tacit knowledge of how to handle challenging situations, or even crises, that arise in the classroom. Tacit knowledge is what a person needs to know to succeed in an endeavor that is typically not explicitly taught and that often is not even verbalized. It is procedural knowledge, and thus is not just a static form of knowledge, but rather, knowledge in use. We constructed a measure of tacit knowledge for elementary-school teachers, in order to determine the teachers’ likely effectiveness in dealing with problematical classroom situations. In Study 1, our primary goal was to determine whether our measure predicted principals’ ratings of the teachers’ classroom performance as well as teachers’ ratings of their own effectiveness. We found that teachers who scored higher on our tacit-knowledge inventory generally were rated as more effective by their principals, but as less effective by themselves. In Study 2, we investigated whether responses to problematical situations that were viewed as better or worse, respectively, in the United States were also viewed as better or worse, respectively, in Israel. We found a high correlation between responses in the two countries. We concluded that it is possible to measure an important aspect of teacher effectiveness via a measure of tacit knowledge, and that comparable measurements may be possible across at least two cultures.  相似文献

OBJECTIVES: To determine whether child witnesses of sexual abuse were more or less informative about the alleged incidents than alleged victims when interviewed similarly. METHOD: Twenty-six alleged victims of child sexual abuse (aged 5 to 14 years; M=9.8 years) and 26 children who had witnessed but not experienced similar events were interviewed by experienced youth investigators about the alleged abuse. Children in the two groups were matched with respect to their age, relationships with the alleged perpetrator, and seriousness of the alleged offenses. All children were interviewed using the NICHD investigative interview protocol. RESULTS: Witnesses and victims provided similar amounts of information about the incidents of abuse. Interviewers used more open-ended invitations and elicited more information using open-ended prompts from witnesses than from victims, whereas they used more risky (including suggestive) prompts when interviewing victims. DISCUSSION: These results confirm that young children can be informative witnesses about events that they have either experienced or witnessed.  相似文献

A Threefold Model of Intellectual Styles   总被引:12,自引:0,他引:12  
The field of styles presents three major controversial issues: styles as value-laden versus value-free, styles as traits versus states, and styles as different constructs versus similar constructs with different labels. We address these issues by proposing an integrative model of styles—the Threefold Model of Intellectual Styles—which divides all styles into three basic kinds. The foundation of this model is Sternberg and Zhangs body of empirical investigations into the thinking styles proposed in the theory of mental self-government. The model also draws upon others previous empirical findings in the literature. The model argues that most styles are value-laden rather than value-free; that they have both trait-like and state-like aspects, but for the most part are modifiable and hence more state-like; and that they overlap highly across theories.  相似文献

Educators know that variables beyond abilities affect students’ performance in school and their interactions with their teachers. Thinking styles are such a variable. Thinking styles are preferred ways of thinking. They are not abilities but rather preferred ways of expressing these abilities. Both students and teachers vary in thinking styles, and in systematic ways. For example, teachers tend to match the stylistic pattern of the school, and students to match the stylistic pattern of their teachers. Teachers tend to overestimate the extent to which their students match their own styles, and also evaluate more favorably students whose styles match their own. Thus, teachers are more likely to identify as “gifted” not only high ability students, but those who match them stylistically.
