Implementing Student‐Centered Learning Practices in a Large Enrollment,Introductory Food Science and Human Nutrition Course     

Debra Korte  Nicholas Reitz  Shelly J. Schmidt 《Journal of Food Science Education》2016,15(1):23-33

Informed by the latest research on how people learn, effective teachers address both aspects of the teaching–learning equation—they engage students in the course material by implementing best teaching practices and they prepare students for learning by sharing best learning practices. The purpose of this study was to evaluate the impact of student‐centered learning practices on students’ perceptions of their ability to learn, specifically in a large enrollment, introductory food science and human nutrition course. Featured student‐centered learning practices included required assignments, optional study tools, and supplemental learning resources. A mixed method survey instrument with 5‐point Likert scales and qualitative, open‐ended questions was used to determine students’ (1) use of optional study tools and supplemental learning resources; (2) perceptions as to the quality and impact of required assignments, optional study tools, and supplemental learning resources to enhance their ability to learn; (3) perceptions as to the usefulness of required assignments, optional study tools, and supplemental learning resources to help them perform better in this course; and (4) overall satisfaction, as a learner, in this course. Overall, students identified study guides (developed using Bloom's taxonomy action verbs) (Mean = 4.34), microthemes (Mean = 4.27), and quizzes (Mean = 4.11) as the most beneficial resources to enhance their learning of the course material. Overall, 85% of students said they were extremely or very satisfied as learners in the course and nearly 75% of the students said the student‐centered learning practices should be offered to future FSHN 101 students.  相似文献   

Creating safe spaces for children’s voices to be heard: supporting the psychosocial needs of children in times of trauma     

Karen Capo  Lori Espinoza  Jordan Khadam-Hir  Debra Paz 《Journal of Early Childhood Teacher Education》2019,40(1):19-30

ABSTRACT

This reflection on practice provides a foundation for understanding the impact of Hurricane Harvey on teachers and children across the Texas Gulf Coast. It also documents the emergence of a professional development initiative born when early childhood teacher educators in the community outreach arm of a major university sought to provide immediate support for colleagues returning to their classrooms in the wake of the disaster. The initiative was designed to promote teachers’ understanding of the theoretical rationale behind supporting the psychosocial development of children in times of trauma and offer specific strategies and activities to help children work through this particular natural disaster, that is, storms, flooding, property destruction, and some physical harm. Implications for early childhood teacher preparation along with recommendations for future action are included.  相似文献   

A Loyalty Tax? National Measures of Academic Salary Compression     

Barbezat  Debra A. 《Research in higher education》2004,45(7):761-776

This paper presents measures of faculty salary compression for 1993 and 1999 based on national, rather than institutional-level, data. Using a recently developed technique and two national faculty surveys, actual junior to senior salary ratios are derived as well as predicted salary ratios that represent what the salary ratios would be if junior and senior faculty were similarly compensated for their productive traits. The analysis, which considers three alternative definitions of junior faculty and stratifies results by institutional type, produces an overall finding of no salary compression. A limited number of disciplines, including business and economics, however, do exhibit signs of salary compression.  相似文献   

Topicalization and the Processing of Expository Prose by Children: mediating effects of cognitive styles and content familiarity     

Beth Davey  Debra Miller 《教育心理学》1990,10(1):23-38

This study assessed the effects of text topicalization conditions (initial position, final position, or no topic sentence) on the comprehension of main ideas and specific passage information for middle school readers. Also of interest were interactions of topic familiarity and readers’ cognitive styles (degree of field independence) with text topicalization. One hundred and seven subjects were randomly assigned to one of the three topicalization conditions and read three familiar and three less‐familiar multipleparagraph expository texts. Main idea comprehension was assessed with both a sentencesummary (generation) and best‐title (recognition) task. Comprehension of specific passage information was evaluated with multiple‐choice items. Text topicalization effects were observed for main idea comprehension (with initial position best, followed by final position), while topic familiarity resulted in higher comprehension scores for specific passage information. Moreover, a cognitive style‐text topicalization interaction was found on the best‐title task; in this case, relatively field dependent readers were assisted by a final topic sentence placement. Implications are drawn for future research concerning the complex interplay of texts, tasks and readers in prose‐processing.  相似文献

Children's agency beliefs, cognitive performance, and conceptions of effort and ability: individual and developmental differences     

M Chapman  E A Skinner 《Child development》1989,60(5):1229-1238

In order to understand how children's beliefs and cognitive performance vary according to development in their conceptions of effort and ability, 120 fourth and sixth graders were given the following assessments: (a) a measure of agency beliefs, defined as the extent to which persons believe they have access to certain classes of potential means, including effort, ability, powerful others, and luck; (b) a battery of intelligence test scales, including figural patterns, letter series, arithmetic, and spelling; (c) an interview designed to assess developmental levels in conceptions of effort and ability. Correlations between intelligence scores and agency beliefs for effort decreased with increasing levels of reasoning about effort and ability, but correlations between intelligence scores and agency beliefs for ability increased with increasing levels of reasoning. No such trends were found in correlations between performance and agency beliefs for luck or for unknown causes. The results are discussed in terms of the interaction between individual differences and developmental change.  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  

Duggan A  Caldera D  Rodriguez K  Burrell L  Rohde C  Crowne SS 《Child abuse & neglect》2007,31(8):801-827

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
