Seeking big ideas in algebra: the evolution of a task     

Eric Hsu  Judy Kysh  Katherine Ramage  Diane Resek 《Journal of Mathematics Teacher Education》2007,10(4-6):325-332

In this paper we describe a strand of activities for teachers of mathematics that we used with two cohorts of participants in a professional development program called Revitalizing Algebra (REAL). We first discuss our goals and describe the participants, and then we describe the construction and selection of the tasks followed by teacher responses. Finally, we reflect on different iterations of the tasks, their impact on the teachers’ thinking and practice, and the role of school and department culture in the process of change.  相似文献   

The effect of services on the recurrence of child maltreatment     

DePanfilis D  Zuravin SJ 《Child abuse & neglect》2002,26(2):187-205

OBJECTIVE: Building on a previous model of recurrence, this study examined the relationship of services on the hazard of child maltreatment recurrence during CPS intervention for families who were provided continuing intervention following a confirmed index report of physical abuse or neglect. METHOD: This nonconcurrent prospective study selected 434 subject families who met study eligibility requirements from 1181 families randomly selected from the 2902 families who had experienced a substantiated report of child abuse or neglect during the sampling year. Data were collected and coded from archival sources for 5 years following the index report. Each record was coded by two research analysts to increase inter-rater reliability. Data were analyzed with the Cox Proportional Regression Model. RESULTS: Case characteristics that predicted recurrence were: child vulnerability, family stress, partner abuse, and social support deficits. After examining the potential effect of nine service-related variables only attendance at services predicted recurrence while controlling for other variables in the model. Families who were noted to attend the services identified in their service plans were 33% less likely to experience a recurrence of child maltreatment while their case was active with CPS. CONCLUSIONS: Implications of this and other research suggests that actively engaging families in a helping alliance and helping them accept and receive services may reduce the likelihood of future maltreatment.  相似文献   

Report of a Staff Program to Promote and Support Breastfeeding in the Care of Vulnerable Infants at a Children's Hospital          下载免费PDF全文

Spatz DL 《The Journal of perinatal education》2005,14(1):30-38

Ill or premature infants do not have the opportunity to begin breastfeeding in an optimal manner; yet, these infants may benefit most from human milk. Health-care providers' knowledge of breastfeeding in both healthy and ill infants is frequently limited due to deficits in training. This article outlines a multifaceted approach to develop a comprehensive, hospital-wide system to support and promote breastfeeding for vulnerable infants. This approach was designed for the staff of the Children's Hospital of Philadelphia.  相似文献   

Secondary science students’ beliefs about class discussions: a case study comparing and contrasting academic tracks     

Diane Silva Pimentel  Katherine L. McNeill 《International Journal of Science Education》2016,38(12):2047-2068

The dialogue that occurs in science classrooms has been the subject of research for many decades. Most studies have focused on the actual discourse that occurs and the role of the teacher in guiding the discourse. This case study explored the neglected perspective of secondary science students and their beliefs about their role in class discussions. The study participants (N?=?45) were students in one of the three differentially tracked chemistry classes taught by the same teacher. Findings about the differences that exist among students from different academic tracks are reported. While it seems that epistemological beliefs focusing on content are common for the students in this study, the students' social framing in the different tracks is important to consider when teachers attempt to transition to more dialogic forms of discourse. Some key findings of this study are (a) students’ beliefs that science is a body of facts to be learned influenced the factors they deemed important for whole-class discussion, (b) students from the lower-level track who typically were associated with lower socioeconomic status were more likely to view their role as passive, and (c) students’ comfort level with the members of the class seemed to influence their decisions to participate in class discussions.  相似文献   

Self‐help in research and development relating to assessment: a case study     

Mantz Yorke  Peter Evanson  Chris Haines  Don Jenkins  Peter Knight 《Assessment & Evaluation in Higher Education》2004,29(4):389-399

This article briefly chronicles nearly a decade of research and development activity undertaken in the area of assessment by a group of committed volunteers, ‘The Student Assessment and Classification Working Group’ (SACWG). However, greater attention is given to demonstrating what a self‐help approach can achieve in respect of research and development in higher education, and to identifying the factors that contribute to success in this respect. It is suggested that the approach has transfer value, provided that certain conditions are met.  相似文献

Tertiary pedagogy encounters the technological imperative     

Diane J. Thompson  Dale M. Holt 《Distance Education》1996,17(2):335-354

In one of the most challenging periods to confront tertiary education, we examine the impact that technology is having on the experience of one open and distance education university: Deakin University in Victoria, Australia. This paper considers how the espoused pedagogical views that were expressed by the academics interviewed, individually and collectively impacted on their attitudes to information technologies and to their reactions to exposure to and experience with various technologies. The first part of the paper explicitly considers the interview as a research method and situates the interviews we undertook within current scholarship. The focus of the interviews was to seek perceptions of what constituted good teaching as well as the relevance of technology for teaching: as each academic defined it; the discipline concerned and the mode of delivery (i.e. on and/or off‐campus). The research did not provide definitive answers but suggested themes and implications which are considered in the Conclusion. Although restricted to the perceptions of five academics at one university, the extent to which each of the ‘case studies' resonates with the reader's experience takes it beyond the experience of the one tertiary institution.  相似文献   

Predicting South Korean University Students’ Happiness through Social Support and Efficacy Beliefs     

Diane Sookyoung Lee  Amado M. Padilla 《International journal for the advancement of counseling》2016,38(1):48-60

This study investigated the adversity and coping experiences of 198 South Korean university students and takes a cultural lens in understanding how social and individual factors shape their happiness. Hierarchical linear regression analyses suggest that Korean students’ perceptions of social support significantly predicted their happiness, particularly in their closer social circles. Additionally, their happiness was significantly shaped by their beliefs in their abilities to overcome difficult experiences, but not by their beliefs in maintaining their relationships. Findings demonstrate the importance of better preparing close family and friends to recognize and respond to warning signs, as well as exploring ways to build students’ internal coping assets within family and peer group settings.  相似文献   

Mothers,fathers, and infants: the role of person familiarity and parental involvement in infants' perception of emotion expressions     

Montague DR  Walker-Andrews AS 《Child development》2002,73(5):1339-1352

The roles of person familiarity and parental involvement in 3.5-month-old infants' sensitivity to the dynamic emotion expressions of others were explored. In the home, parental facial/vocal expressions (happy, sad, angry) were videotaped, and measures of parent-infant involvement were obtained. In the laboratory, 32 infants alternately viewed their mother and father and an unfamiliar woman and man portraying expressions in an intermodal preference task. Infants looked differentially at mothers' expressions but not at those of fathers or unfamiliar adults. Examination of parent-child involvement patterns revealed significant relations with infants' sensitivity to expressions. Results suggest that person familiarity may facilitate infants' developing understanding of others' emotion expressions, and that individual differences in family dynamics may be relevant to infants' patterns of responding.  相似文献
