ABSTRACT Creativity research has unsettled education by newly defining neglected abilities, and by proposing new methods like training in questioning abilities, but conventional methods do not encourage students to learn or think by asking good questions. We need to cultivate the full spectrum of talents by bridging the research—classroom practice gap. A proposed three-dimensional model for analyzing curricula, courses, and classes would show us where we are not doing a good job in teaching students to think while we are simultaneously teaching them subject-matter content. Content is best learned as a by-product of thinking or learning processes. The proposed model capitalizes on transfer effects of both processes and content, and may be of value in working, not only with those highest in a talent, but also with the educationally deprived. Every student should learn to use each of his abilities at some point in the educational process, but different teachers may specialize in various contents, processes, or methods. 相似文献

A study is reported in which the relations among normal aging, source amnesia, and frontal lobe functioning were explored. Twenty-four older adults (aged 60-84 years) were tested on their ability to remember where they had acquired new factual information; they were also given the Wisconsin Card Sorting Test (WCST), a test of verbal fluency, and other psychometric tests. The degree of source amnesia in this normal sample correlated with age, verbal fluency, and some measures from the WCST. Source amnesia was not related to Performance IQ, however, or to a measure of fact recall. The implications for the relations among aging, memory, and frontal lobe functions are discussed. 相似文献

A survey was conducted to examine high-risk sexual behavior in a large group of adolescents who were involved with the juvenile justice system. The findings showed that these youth are at high risk for unintended pregnancy and AIDS and other sexually transmitted diseases. Compared to national norms, the sample reported a very early mean age at first intercourse and a high rate of pregnancy. Those who had been involved in a pregnancy reported having begun sexual activity the earliest of those surveyed. Most participants reported an extremely unreliable use of birth control, with this unreliable use of birth control being strongly associated with espousal of high-risk attitudes but generally unassociated with factual knowledge regarding pregnancy and contraception. These findings support the argument for expanding the scope of traditional sex education and beginning sexuality education programs earlier than they usually are in this country. 相似文献
