This article shares the perspectives of two former high school and middle school librarians who moved into academic libraries. The move from the K–12 sector to higher education offered them unique insights into working with first-year students as they started their college careers. Existing literature discusses the importance of collaboration between high school and academic librarians. The authors of this article have firsthand experience of how students work in the middle and high school realm, and they demonstrate how to apply that knowledge and experience with college students.  相似文献

Racial identity and academic attainment among African American adolescents   总被引:2,自引:0,他引:2  
In this study, the relationships between racial identity and academic outcomes for African American adolescents were explored. In examining race beliefs, the study differentiated among (a) importance of race (centrality), (b) group affect (private regard), and (c) perceptions of societal beliefs (public regard) among 606 African American 17-year-old adolescents. Using cluster analysis, profiles of racial identity variables were created, and these profile groups were related to educational beliefs, performance, and later attainment (high school completion and college attendance). Results indicated cluster differences across study outcomes. Also, the relationships between academic attitudes and academic attainment differed across groups. Finally, the paper includes a discussion on the need to consider variation in how minority youth think about group membership in better understanding their academic development.  相似文献

Meta-analyses of active-learning research consistently show that active-learning techniques result in greater student performance than traditional lecture-based courses. However, some individual studies show no effect of active-learning interventions. This may be due to inexperienced implementation of active learning. To minimize the effect of inexperience, we should try to provide more explicit implementation recommendations based on research into the key components of effective active learning. We investigated the optimal implementation of active-learning exercises within a “lecture” course. Two sections of nonmajors biology were taught by the same instructor, in the same semester, using the same instructional materials and assessments. Students in one section completed in-class active-learning exercises in cooperative groups, while students in the other section completed the same activities individually. Performance on low-level, multiple-choice assessments was not significantly different between sections. However, students who worked in cooperative groups on the in-class activities significantly outperformed students who completed the activities individually on the higher-level, extended-response questions. Our results provide additional evidence that group processing of activities should be the recommended mode of implementation for in-class active-learning exercises.  相似文献

We describe an assessment of the collective impact of 35 grants that the Howard Hughes Medical Institute (HHMI) made to biomedical research institutions in 1999 to support precollege science education outreach programs. Data collected from funded institutions were compared with data from a control group of institutions that had advanced to the last stage of review but had not been funded. The survey instrument and the results reveal outcomes and impacts that HHMI considers relevant for these programs. The following attributes are considered: ability to secure additional, non-HHMI funding; institution buy-in as measured by gains in dedicated space and staff; enhancement of the program director''s career; number and adoption of educational products developed; number of related publications and awards; percentage of programs for which teachers received course credit; increase in science content knowledge; and increase in student motivation to study science.  相似文献

Open-ended, short-answer questions, referred to as constructed responses (CR), allow students to express knowledge and skills through their own words. While CRs can reduce the likelihood of guessing correct answers, they also enable students to provide errant responses due to a lack of knowledge or a misunderstanding of the question. Conversation-based assessments (CBAs) require constructing responses to open-ended prompts (similar to CRs), but also leverage natural-language processing to provide adaptive follow-up prompts that target particular information. This work describes an investigation into potential benefits of CBAs as they are compared to a CR approach. Results from 632 middle schoolers indicate that, when compared to CRs, the CBA items allowed 41% of students to provide a more complete response and improve their score.  相似文献

Impact of a statewide home visiting program to prevent child abuse   总被引:1,自引:0,他引:1  
OBJECTIVES: To assess the impact of a voluntary, paraprofessional home visiting program in preventing child maltreatment and reducing the multiple, malleable psychosocial risks for maltreatment for which families had been targeted. METHODS: This collaborative, experimental study focused on 6 Healthy Families Alaska (HFAK) programs; 325 families were enrolled in 2000-2001, randomized to intervention and control groups, and interviewed to measure baseline attributes. Follow-up data were collected when children were 2 years old (85% follow-up rate). Outcomes included maltreatment reports, measures of potential maltreatment and parental risks, for example, poor mental health, substance use, and partner violence. HFAK records were reviewed to measure home visiting services. Home visitors were surveyed to measure perceived effectiveness and training adequacy. RESULTS: Parental risks were common at baseline, and one-sixth of families had a substantiated child protective services report in the child's first 2 years of life. There was no overall program effect on maltreatment reports, and most measures of potential maltreatment. Home visited mothers reported using mild forms of physical discipline less often than control mothers. The groups were similar in their use of more severe forms of physical discipline. There was no program impact on parental risks. There was no impact on outcomes for families with a 'high dose' of home visiting. Home visitors often failed to address parental risks and seldom linked families with community resources. Contradictions in the model compromised effectiveness. CONCLUSIONS: The program did not prevent child maltreatment, nor reduce the parental risks that had made families eligible for service. Research is needed to develop and test strategies to improve the effectiveness of home visiting.  相似文献

This ethnographic case study investigated the science practices of teachers at one public elementary magnet school in light of how school culture influenced science curriculum design and instruction. The purpose of the study was to address how school culture impacted the school??s overall treatment of science as a viable content area. Key informant teachers were interviewed to explore their personal beliefs and values, teaching, access to materials, and views of the adopted integrated thematic curriculum model and magnet structure. The resulting data, triangulated with informal observation and artifact collection, were analyzed using a theoretical framework that emphasized five interdependent school culture indicators (values, beliefs, practices, materials, and problems). Findings suggest that the school??s culture adversely influenced the treatment of science.  相似文献

The influence of parenting skills on adolescent outcomes among children affected by maternal HIV/AIDS (N = 118, M age = 13) was investigated. Among families with more frequent family routines, over time adolescents showed lower rates of aggression, anxiety, worry, depression, conduct disorder, binge drinking, and increased self‐concept. Among families with higher levels of parental monitoring, adolescents showed significant declines in anxiety and depression, conduct disorder, and binge drinking, along with increased self‐concept. Mothers’ level of illness was associated with parenting. Greater variability in parental monitoring resulted in higher levels of problem behaviors.  相似文献
