Guided by control theory, this study examines memorable messages that women on probation and parole receive from their probation and parole agents. Women interviewed for the study were asked to report a memorable message they received from an agent, and to describe situations if/when the message came to mind in three contexts likely to emerge from a control theory perspective: when they did something of which they were proud, when they stopped themselves from doing something they would later regret, and when they did something of which they were not proud. The types of memorable messages and the reactions to these messages within the three contexts were coded, and differences between women on probation versus parole were examined. Overall, a greater proportion of women on parole recalled memorable messages, and the most frequently reported type of memorable message was behavioral advice. Women reported that the message helped them do things of which they were proud, such as engaging in routine activities and fulfilling goals; helped them to not give into urges that could lead to further negative sanctions or feelings of regret; and came to mind when they relapsed. Practical implications of the findings for training are presented.  相似文献

Although curiosity is considered an integral aspect of science learning, researchers have debated how to define, measure, and support its development in individuals. Prior measures of curiosity include questionnaire type scales (primarily for adults) and behavioral measures. To address the need to measure scientific curiosity, the Science Curiosity in Learning Environments (SCILE) scale was created and validated as a 12-item scale to measure scientific curiosity in youth. The scale was developed through (a) adapting the language of the Curiosity and Exploration Inventory-II [Kashdan, T. B., Gallagher, M. W., Silvia, P. J., Winterstein, B. P., Breen, W. E., Terhar, D., & Steger, M. F. (2009). The curiosity and exploration inventory-II: Development, factor structure, and psychometrics. Journal of Research in Personality, 43(6), 987–998] for youth and (b) crafting new items based on scientific practices drawn from U.S. science standards documents. We administered a preliminary set of 30 items to 663 youth ages 8–18 in the U.S.A. Exploratory and confirmatory factor analysis resulted in a three-factor model: stretching, embracing, and science practices. The findings indicate that the SCILE scale is a valid measure of youth’s scientific curiosity for boys and girls as well as elementary, middle school, and high school learners.  相似文献

As concerns about participation rates in post-compulsory science continue unabated, considerable research efforts have been focused on understanding and addressing the issue, bringing various theoretical lenses to bear on the problem. One such conceptual lens is that of ‘science capital’ (science-related forms of social and cultural capital), which has begun to be explored as a tool for examining differential patterns of aspiration and participation in science. This paper continues this line of work, attempting to further refine our conceptualisation of science capital and to consider potential insights it might offer beyond existing, related constructs. We utilise data from two surveys conducted in England as part of the wider Enterprising Science project, a broader national survey and a more targeted survey, completed by students from schools generally serving more disadvantaged populations. Logistic regression analyses indicated that science capital was more closely related than cultural capital to science aspirations-related outcome variables. In addition, further analyses reflected that particular dimensions of science capital (science literacy, perceived transferability and utility of science, family influences) seem to be more closely related to anticipated future participation and identity in science than others. These patterns held for both data sets. While these findings are generally in alignment with previous research, we suggest that they highlight the potential value of science capital as a distinct conceptual lens, which also carries particular implications for the types of interventions that may prove valuable in considering ways to address disparities in science engagement and participation.  相似文献

Research Findings: Effects on children’s school readiness were evaluated for 2 interventions focused on improving teacher–student interactions (coursework, coaching) implemented sequentially across 2 years. Teachers from public prekindergarten programs in 10 locations were assigned randomly to treatment or control conditions in each year. Children’s language behavior was observed during the coaching year: Coaching and the course each had positive impacts on children’s multiword language behavior. Treatment impacts on directly assessed literacy, language, and self-regulation skills were evaluated within an intent-to-treat framework for children taught by the participating teachers in the coaching and postcoaching years. Children demonstrated higher levels of inhibitory control in direct assessments when their teacher had received coaching the prior year. Teachers who received both coursework and coaching reported in the postcoaching year that children in their classrooms demonstrated greater levels of behavioral control. Treatment effects did not differ as a consequence of child, classroom, or program characteristics, and there were no significant effects on directly assessed literacy or language skills. Practice or Policy: Results suggest modest benefits for children’s language behavior and self-regulation for intervention(s) that improve the quality of teacher–child interaction.  相似文献

The achievement gap in mathematics between African American and Caucasian students has been observed for several decades, though previous research has been unable to fully explain why the gap exists. Using a sample of 56 kindergarten and first grade students, this study examined the role that cognitive developmental level plays in the achievement gap. Results indicated that African American students scored significantly lower than the Caucasian students on a test of mathematical achievement. Furthermore, proportionally more African American students remained in the preoperational stage of development as compared to their same-age Caucasian peers. Finally, after controlling for cognitive developmental level, the achievement gap between the two groups became statistically indistinguishable, suggesting that cognitive developmental level mediates the relationship between ethnicity and mathematic achievement.  相似文献

Proficient readers engage in a wide range of cognitive and metacognitive strategies, and both developmental and classroom intervention researchers are in need of high-quality measures of strategy use. Several researchers have recently called into question the validity of the most common type of measures of strategy use in reading, self-report or introspective measures (i.e., the participant must report on his or her cognitive activity while not actually engaged in the activity). We administered three parallel strategy use measures to a sample of 30 ninth-grade students: a prospective self-report measure, a concurrent multiple-choice measure which required students to apply the strategies to specific passages, and a text on which we asked students to think aloud. We also collected two measures of reading comprehension—a standardized measure and free recall scores. Consistent with Veenman’s (2005) conclusions based on a literature review, the concurrent multiple-choice and think-aloud data were both significantly correlated with both of the comprehension scores and with each other, whereas the prospective self-report data had non-significant correlations with all of the other measures. We conclude by recommending concurrent measures for researchers who wish to study strategy use in reading comprehension.  相似文献
