A randomized prevention trial contrasted families who took part in the Strong African American Families Program (SAAF), a preventive intervention for rural African American mothers and their 11-year-olds, with control families. SAAF is based on a contextual model positing that regulated, communicative parenting causes changes in factors protecting youths from early alcohol use and sexual activity. Parenting variables included involvement-vigilance, racial socialization, communication about sex, and clear expectations for alcohol use. Youth protective factors included negative attitudes about early alcohol use and sexual activity, negative images of drinking youths, resistance efficacy, a goal-directed future orientation, and acceptance of parental influence. Intervention-induced changes in parenting mediated the effect of intervention group influences on changes in protective factors over a 7-month period. 相似文献

Vocabulary knowledge was tested in a native (Cantonese-Chinese) and foreign (English) language in 150 twins and 150 singletons aged 6–11 years, matched on age, gender, grade level, nonverbal intelligence, parents’ education, family income, and number of siblings and household members. The singletons clearly outperformed the twins on the native vocabulary, but this “twinning effect” was much less noticeable for the foreign vocabulary. The effect on English vocabulary was further reduced after exposure to English at home was controlled. Given that these participants learned most of their English in school rather than home, the present findings support the notion that the twinning effect is associated with increased competition for family interaction in twins compared with singletons. 相似文献

Research in science education confirms the importance of self-efficacy in students' persistence and success in the sciences. The current study examined the role of science self-efficacy in nonspecialist, arts and communication-oriented students encountering science in a general education context. Participants (N = 275) completed a beginning- and end-of-semester survey including a Science Self-Efficacy Scale, a “connection to science” measure—the Inclusion of Science in Self Scale—and a Science Anxiety Scale. Participants also responded to two open-ended “sources of science efficacy” questions, and provided background/demographic information and access to their academic records. Results showed a significant increase in science self-efficacy and connection to science—although no change in science anxiety—over the course of the semester. The observed shift in self-efficacy for minority and international students was of particular note. These students started the course with lower confidence but, by the end of the semester, reported comparable science self-efficacy, and achieved similar grades to their White/Non-Hispanic and US resident classmates. Contrary to expectations, science self-efficacy did not predict performance in the class. However, students' self-reported sources of efficacy indicated increased confidence in using science in daily life, and confirmed the value of mastery experiences and of personally meaningful, student-centered course design in scaffolding student confidence. Results are discussed in terms of the individual and instructional factors that support science self-efficacy and student success in this unique, general education science environment. 相似文献

Abstract Nine males (age 24.7 ± 2.1 years, height 175.3 ± 5.5 cm, body mass 80.8 ± 7.2 kg, power clean 1-RM 97.1 ± 6.36 kg, squat 1-RM = 138.3 ± 20.9 kg) participated in this study. On day 1, the participants performed a one-repetition maximum (1-RM) in the power clean and the squat. On days 2, 3, and 4, participants performed the power clean, squat or jump squat. Loading for the power clean ranged from 30% to 90% of the participant's power clean 1-RM and loading for the squat and jump squat ranged from 0% to 90% of the participant's squat 1-RM, all at 10% increments. Peak force, velocity, and power were calculated for the bar, body, and system (bar + body) for all power clean, squat, and jump squat trials. Results indicate that peak power for the bar, body, and system is differentially affected by load and movement pattern. When using the power clean, squat or jump squat for training, the optimal load in each exercise may vary. Throwing athletes or weightlifters may be most concerned with bar power, but jumpers or sprinters may be more concerned with body or system power. Thus, the exercise type and load vary according to the desired stimulus. 相似文献

The purpose of this study was to examine the differential effect of sport skills instruction (SSI) and sport skills instruction plus initiative games (SSI +) on the critical thinking (CT) and self-esteem scores of early adolescent boys placed at risk. Students in the SSI + group ( n = 36) participated in initiative games classes in addition to their sport skills activities. Students in the SSI group (n = 44) participated in the sport skills activities only. Since the boys were divided by age (10-11 & 12-13), the influence of age on the dependent variables was also investigated. Classes taught by the initiative games teacher were student-centered while the sport skills classes were teacher-centered. Significant differences between teacher behaviors occurred in interaction patterns, instructional strategies, and management concerns. There were no differences on self-esteem scores. The results supported the addition of initiative games to SSI to foster CT with this group of participants. 相似文献

This paper discusses the development of an interactive approach to teaching and assessing a microanatomy curriculum in an innovative medical school program. As an alternative to lectures and labs, students are engaged in interactive seminars focused on discussion of clinical and research‐based cases matched with normal histology and pathology slides. A virtual microscopic system is used rather than the traditional glass slide and light microscope. Evaluation of student performance consists of self‐assessment board style questions, concept appraisal problems, and utilization of a portfolio system where the assessment pieces are continuously integrated as part of written formative and summative assessments.

This paper presents a qualitative investigation of the motivators, barriers, and facilitators for practicing family-style meal service (FSMS) from the perspective of 18 child care providers serving preschool children in Head Start (HS), Child and Adult Care Food Program (CACFP) funded, and non-CACFP child-care centers. Providers were selected based on maximum variation purposive sampling and semi-structured interviews were conducted until saturation was reached. Provider responses were systematically coded using thematic analysis. HS and CACFP providers reported being motivated to practice FSMS because it created pleasant mealtimes, opportunities to role model healthy eating, and healthful child development. CACFP and non-CACFP providers reported not using FSMS because it was resource intensive, messy, and seemed to violate CACFP policy. HS and CACFP providers offered suggestions to overcome these barriers. They suggested that FSMS eventually becomes easier with practice, children can self-regulate their energy intake, and teaching children self-help skills during play time can avoid messes during mealtimes. Findings from this study have implications for programming, policy, and research. 相似文献
