A paucity of research has directly compared empirically supported interventions to examine their effectiveness among students with different mathematics fluency skills. The purpose of this study was to compare the effects of two empirically supported interventions and a control condition on the mathematics fluency of 98 second and third grade students. Specifically, effects of explicit timing and cover-copy-compare on subtraction fluency were examined each session, which occurred twice weekly for a total of six weeks. HLM was used to examine progress during the intervention sessions and determine the effect of initial fluency level on intervention effectiveness. Results suggested students' initial level of fluency impacted intervention effectiveness. That is, for students whose fluency levels fell within the frustrational range CCC and control conditions resulted in the best performance over time but for children whose fluency was in the instructional range explicit timing was the most effective treatment. 相似文献

Telephone versus print delivery of an individualized motivationally tailored physical activity intervention: Project STRIDE. 总被引:3,自引:0,他引:3

OBJECTIVE: Given that only 25% of Americans meet physical activity recommendations, there is a need to develop and disseminate effective, evidence-based interventions to promote physical activity. The authors tested 2 delivery channels, telephone and print, to determine whether one was more effective in promoting physical activity. DESIGN: The authors randomly assigned 239 healthy, sedentary adults to (a) telephone-based individualized feedback, (b) print-based individualized feedback, or (c) contact control. Both intervention arms were guided by a motivationally tailored, theoretically driven computer expert system. MAIN OUTCOME MEASURES: Physical activity as measured by the 7-day Physical Activity Recall interview. RESULTS: At 6 months, both telephone and print arms significantly increased in minutes of moderate intensity physical activity compared with control, with no differences between the intervention arms. At 12 months, print participants reported a significantly greater number of moderate intensity minutes than both telephone and control participants, who did not differ. CONCLUSION: Results suggest that both telephone and print enhance the adoption of physical activity among sedentary adults; however, print interventions may be particularly effective in maintaining physical activity in the longer term. 相似文献

Other-race individuals are remembered more poorly and receive less holistic/configural processing than same-race individuals, at least when faces are novel. Here, we examine the amelioration of these effects with familiarity, using distinctiveness-matched Caucasian and Asian stimulus sets. We confirmed a cross-race deficit for upright faces following a single encoding trial, which disappeared rapidly with practice on a small set of other-race 'friends' and did not re-emerge when perceptual processing was put under stress (presentation in the periphery). We also examined holistic/configural processing for familiarised faces using the peripheral inversion effect (McKone, 2004 Journal of Experimental Psychology: Learning, Memory, and Cognition 30 181 - 197). A test for faces and nonface objects (dogs) confirmed the validity of this technique as providing a direct measure of holistic processing; we then showed that, after 1 h of training, holistic processing was as strong for other-race as same-race faces. We conclude that practice with other-race individuals can rapidly engage normal face-processing mechanisms. 相似文献

What roles do ethnicity, gender, and attitudes play in determining whether a person will be perceived as a unique individual versus a homogenized group member? Attitudes toward women’s roles have been found to predict Whites’ relative individuation of women and men; however, African Americans were found to individuate women and men equally, regardless of attitude (Stewart et al. 2000). Using a name–trait matching paradigm, the present research found that when targets were identified as African American, African American participants’ (18 male and 35 female college students) attitudes toward women’s roles predicted their individuation of men and women. These results suggest that an ethnic out-group homogeneity effect, rather than gender-egalitarian attitudes, contributed to the previous finding of equivalent individuation. 相似文献

A meta-analysis of the data relating either college athletic participation or fraternity membership to attitudes and behaviors
associated with sexual aggression was conducted with 29 studies which yielded 57 effect sizes. Membership in each male group
was associated to a moderate extent with rape-supportive attitudes, and to a smaller extent with self-report of sexually aggressive
behavior. There was much variability in the data that could be partially predicted by variables such as the size of the college,
the validity of the study, and the age of the research participants. The involvement of these all-male groups in the perpetuation
of hypermasculine attitudes (Mosher and Sirkin 1984) in a patriarchal culture was discussed. 相似文献

Forty-nine suicide cases were drawn from an original sample of 151 consecutive youth suicide deaths. We used information from 270 interviews with parents and other survivors to evaluate mental health treatment sought for and by the decedent and barriers to mental health treatment. Participants reported the same primary barriers for the decedent: belief that nothing could help, seeking help is a sign of weakness or failure, reluctance to admit to having mental health problems, denial of problems, and too embarrassed to seek help. It is suggested that the stigma of mental illness is a considerable barrier to mental health treatment. 相似文献

This study examined parental role salience, expectations and intentions, and the extent to which the internalization of gender associated traits may be related to these parenting variables within emerging adults. Childless undergraduates at a western Canadian university (N?=?236; 119 women) completed a self-report questionnaire. As predicted, role salience and expectations were positively correlated with intentions. Internalization of expressive/feminine traits, but not instrumental/masculine traits, was positively correlated with all three parenting variables, although gender moderated this relation. While femininity was unrelated to the expectations of women, men possessing more expressive traits held more positive views than their less expressive male counterparts. The implications of these findings are discussed in terms of the parental roles anticipated by young women and men. 相似文献

The present paper analyzes the self-generated explanations (from talk-aloud protocols) that “Good” and “Poor” students produce while studying worked-out examples of mechanics problems, and their subsequent reliance on examples during problem solving. We find that “Good” students learn with understanding: They generate many explanations which refine and expand the conditions for the action parts of the example solutions, and relate these actions to principles in the text. These self-explanations are guided by accurate monitoring of their own understanding and misunderstanding. Such learning results in example-independent knowledge and in a better understanding of the principles presented in the text. “Poor” students do not generate sufficient self-explanations, monitor their learning inaccurately, and subsequently rely heavily on examples. We then discuss the role of self-explanations in facilitating problem solving, as well as the adequacy of current AI models of explanation-based learning to account for these psychological findings. 相似文献
