Cooperative learning in the tutorials of a large lecture physics class     

Paul D. Cottle  Gerald E. Hart 《Research in Science Education》1996,26(2):219-231

The introduction of in-class cooperative learning to a two semester large lecture college physics sequence was evaluated using both qualitative and quantitative measuremets. The first semester of the sequence was taught using traditional formats for lectures, tutorials and laboratories. A group of six students with apparent weaknesses in their academic backgrounds (from a class size of 200) was examined closely through weekly group meetings, journal writing and formal interviews. After several weeks, the group meetings became cooperative learning sessions, and the meetings appear to have helped the students to achieve at a higher level than expected. In addition, a classroom environment survey was administered during the first semester. During the second semester, in-class cooperative learning was implemented in tutorials. Student reaction to the new tutorial format, as measured by the survey, was positive. Field notes taken during the tutorials in the second semester revealed additional positive aspects of this reform. Many of the data support the hypothesis that in-class cooperative learning addressed student concerns about the learning environment and was perceived as an effective reform by most students.  相似文献   

Understanding Television Audiences     

Andrew Hart 《Learning, Media and Technology》1992,18(1):5-21

This article explores some of the methods currently used for studying television audiences and suggests some new possibilities for teaching about them. These include analysis of ‘hard’ data about television audiences and more subjective insights gained from the experience of being part of an audience. It will offer a framework of questions which ought constantly to be asked about television audiences. For example: what is a television audience? What pleasures do television audiences derive from programmes? How are television audiences composed? How are they addressed? How is television audience research carried out? How do television audiences respond to programmes? And finally, what are the implications of an increased understanding of television audiences for broadcasters and educational television producers?.  相似文献   

Educational Media: innovation and evaluation     

A. Hart 《Learning, Media and Technology》1988,14(3):201-212

Reliance on the power of audiovisual media in nurse education has substantially increased in the last few years. This has been especially so when changing approaches to patient care have required large‐scale innovations in clinical and educational practice. Successful innovation depends on effective educational provision and audiovisual media such as videotape and videodisc have been expected to act as powerful agents in this process. Yet there has been little research on the effectiveness of such media. This article examines what actually happened when the multi‐media package Who Cares? (1983) was used in the United Kingdom. The package consisted of two video films and a teacher's handbook.

All known users of the package in the United Kingdom were followed up in order to establish what sort of people used it, in what contexts, how its use was organised and how effective it was for learners. This article explores how the specific educational contexts in which media are used play a vital role in making learning effective. Relevant theory is examined to provide a model of how teachers and learners use media. The results of the research are closely related to recent developments in education and training and, finally, practical recommendations are made for improving the efficiency and effectiveness with which modern educational media are used.  相似文献   

An instructional intervention's impact on the science and literacy achievement of culturally and linguistically diverse elementary students     

Okhee Lee  Rachael A. Deaktor  Juliet E. Hart  Peggy Cuevas  Craig Enders 《科学教学研究杂志》2005,42(8):857-887

This research examined the impact of the first‐year implementation of an instructional intervention to promote achievement and equity in science and literacy for culturally and linguistically diverse elementary students. The research addressed three areas: (a) overall science and literacy achievement, (b) achievement gaps among demographic subgroups, and (c) comparison with national (NAEP) and international (TIMSS) samples of students. The research involved 1,523 third‐ and fourth‐grade students at six elementary schools in a large urban school district. Significance tests of mean scores between pre‐ and posttests indicate statistically significant increases on all measures of science and literacy at both grade levels. While achievement gaps widened with third graders on some of the measures, the gaps tended to narrow with fourth graders. The results based on item‐by‐item comparisons with NAEP TIMSS samples of students indicated overall positive performance of the students in the research at the end of the school year. © 2005 Wiley Periodicals, Inc.

Executive Functioning and School Readiness Among Preschoolers With Externalizing Problems: The Moderating Role of the Student–Teacher Relationship     

Paulo A. Graziano  Leanna R. Garb  Rosmary Ros  Katie Hart  Alexis Garcia 《Early education and development》2016,27(5):573-589

Research Findings: The objective of this study was to examine the student–teacher relationship as a potential moderator of the link between executive functioning (EF) and children’s early school readiness among a clinical sample of preschoolers with externalizing behavior problems (EBP). Participants for the study included 139 preschool children (75.54% boys, M age = 5.01 years, 84.94% Hispanic/Latino) with at-risk or clinically elevated levels of EBP. The student–teacher relationship was assessed using the Student–Teacher Relationship Scale. School readiness data were composed of standardized achievement test scores and teacher reports of kindergarten readiness. EF was measured via parent and teacher reports along with standardized measures of EF, including the Head–Toes–Knees–Shoulders task and 4 standardized subtests from the Automated Working Memory Assessment. Poorer student–teacher relationship quality was predictive of lower teacher-reported kindergarten readiness and higher academic impairment. Main effects were qualified by an interaction between EF and student–teacher relationship quality such that worse EF (parent/teacher reports and standardized performance) was only associated with lower teacher-rated kindergarten readiness for children with poorer student–teacher relationship quality. Practice or Policy: EF appears to be an important predictor of school readiness for preschool children with EBP, particularly for children experiencing poorer student–teacher relationships.  相似文献   

Improving science inquiry with elementary students of diverse backgrounds     

Peggy Cuevas  Okhee Lee  Juliet Hart  Rachael Deaktor 《科学教学研究杂志》2005,42(3):337-357

This study examined the impact of an inquiry‐based instructional intervention on (a) children's ability to conduct science inquiry overall and to use specific skills in inquiry, and (b) narrowing the gaps in children's ability among demographic subgroups of students. The intervention consisted of instructional units, teacher workshops, and classroom practices. The study involved 25 third‐ and fourth‐grade students from six elementary schools representing diverse linguistic and cultural groups. Quantitative results demonstrated that the intervention enhanced the inquiry ability of all students regardless of grade, achievement, gender, ethnicity, socioeconomic status (SES), home language, and English proficiency. Particularly, low‐achieving, low‐SES, and English for Speakers of Other Languages (ESOL) exited students made impressive gains. The study adds to the existing literature on designing learning environments that foster science inquiry of all elementary students. © 2005 Wiley Periodicals, Inc.

Relational and Physical Aggression of Preschool-Age Children: Peer Status Linkages Across Informants   总被引：1，自引：0，他引：1  

David A. Nelson  Clyde C. Robinson  Craig H. Hart 《Early education and development》2005,16(2):115-140

Little is known concerning how subtypes of aggression (relational and physical) might be differentially related to preschool-age children's classification in peer sociometric status groups (popular, average, rejected, neglected, and controversial). Furthermore, associations between aggression and sociometric status might vary according to the assessment tools utilized (e.g., peer report vs. teacher report). In this study, relational and physical aggression as well as sociable behavior of preschool-age children was assessed using peer reports and teacher reports. Peer nominations of acceptance and rejection (like and dislike nominations) were also collected and used to form sociometric status groups. Findings indicate that the behavioral differences between sociometric status group categories, obtained with older samples in previous research, is already evident as early as preschool. Furthermore, relational aggression is associated with controversial sociometric status in this age group (based on peer reports). These findings complement an emerging body of research indicating that the practice of relational aggression may be associated with greater peer status for some children.  相似文献   

Narratives of ‘doing,knowing, being and becoming’: examining the impact of an attachment-informed approach within initial teacher education     

Sarah Kearns  Norma Hart 《Teacher Development》2017,21(4):511-527

The Scottish Government’s vision of improving outcomes for children prioritises attachment theory and research in promoting children’s well-being across children’s services. This theme is also noted as increasing international relevance. Our narrative research springs from the experience of designing and delivering the first course within initial teacher education in Scotland to focus on the application of attachment theory to the role and identity of the teacher – particularly, in supporting children vulnerable through experiences of trauma and adversity. We capture students’ ‘real time’ learning moments through reflective journaling during school experience within the analytic ‘Doing, knowing, being and becoming’. Emergent themes include: looking behind and responding to behaviours, making links with ‘lived lives’, understanding teachers’ potential as attachment figures and ‘secure base’, understanding the relevance of adult attachment theory and resilience/self-care to teachers’ emotions and their own attachment experiences.  相似文献   

The statistical knowledge gap in Higher Degree by Research students: the supervisors’ perspective     

James Baglin  Claire Hart  Sarah Stow 《高等教育研究与发展》2017,36(5):875-889

This study sought to gain an understanding of the current statistical training and support needs for Australian Higher Degree by Research (HDR) students and their supervisors. The data reported herein are based on the survey responses of 191 (18.7%) eligible supervisors from a single Australian institution. The survey was composed of both forced-choice and open-ended items relating to supervisors’ background and experience, supervisors’ perceptions of their own statistical knowledge, the capabilities of their HDR students and supervisors’ attitudes towards the provision of statistical support for HDR students. Most supervisors described themselves as being at either an intermediate or advanced level of statistical experience (74.4%) and were moderately to very confident (72.3%) supervising students in relation to statistical matters. In contrast, supervisors identified a substantial discordance, or gap, between HDR students’ statistical knowledge, which they rated at an overall introductory or lower level (76.6%), and a requirement to have at least an intermediate level of statistical knowledge to complete their degree (74.5%). The findings suggest that supervisors perceive HDR students’ statistical knowledge to be underdeveloped, that both students and supervisors are likely to benefit from the provision of formal statistics training and that supervisors value access to statistical consultancy services.  相似文献   

Influence of a shared leadership model in creating a school culture of inquiry and collegiality     

Claudia Khourey‐Bowers  Richard L. Dinko  Raymond G. Hart 《科学教学研究杂志》2005,42(1):3-24

The purpose of this study was to assess the effectiveness of a Local Systemic Change (LSC) initiative (N = 216) at Year 2 in a 5‐year plan. Key questions were: What is the extent of school and teacher involvement?; What is the impact on teacher preparedness, attitudes, and beliefs?; and What is the extent of institutionalization? The model of professional development used shared leadership (Lead Teachers & Study Groups) along with workshops in inquiry, content, and assessment. All teachers averaged 81 hours of participation by the end of Year 2; LTs averaged 161 hours. Longitudinal and episodic data were collected using multiple instruments, including Horizon Research Teacher Survey (Baseline and Year 2), SG and Lead Teacher surveys (Year 1 and Year 2), Context Beliefs About Teaching Science and Classroom Observation Protocol (Year 2). Gains in teachers' practices, beliefs, and professional culture (collegiality and department chair support) were measured at significance levels of .05. The results indicate that sustained and intensive professional development influences individuals and school culture. © 2004 Wiley Periodicals, Inc. J Res Sci Teach 42: 3–24, 2005  相似文献
