Abstract

Student absenteeism is a widespread and critical issue in early childhood education. Current efforts to reduce student absenteeism in both preschool and K–12 settings have largely been family- and parent-focused interventions. Yet, interventions targeting teachers and schools may similarly be effective tools to improve student attendance. We utilize data from a large-scale, experimental evaluation of an early childhood professional development intervention to examine whether it impacted children’s absenteeism and chronic absenteeism. Although the professional development targeted the quality of teacher-child interactions and did not target children’s absenteeism, we find that the professional development reduced student absence rates by 1.0 percentage points (equivalent to approximately an additional 1.9?days of preschool). The professional development also reduced chronic absenteeism by 6.0 percentage points. Impacts were concentrated among lower-income children. Implications for policies targeting student absenteeism in preschool settings are discussed.  相似文献

Background: Research regarding students’ ideas about the nature of sound reveals a variety of conceptions about sound. In order to reconstruct these ideas and explain sound phenomena, researchers’ teaching interventions often make use of everyday-life contexts. However existing research on sound only partially addresses the correlation between the properties of sound and its perceptive characteristics.

Purpose: To identify the evolution of students’ conceptions regarding the nature of sound and its properties (frequency, intensity and frequency spectrum) through a teaching-learning sequence (TLS) about sound phenomena in an authentic musical context. The described TLS consists of three activities aiming students to correlate the properties of sound waves (frequency, intensity and frequency spectrum) with its perceptive characteristics (pitch, loudness and timbre) via the use of smartphone applications.

Sample: Eight students, in the second year of their studies in the Department of Primary Education of the XXX University.

Design and methods: Students’ perspectives on sound and their progression are investigated through a teaching experiment design. Data are collected by recording students’ interviews. Due to the explorative nature of the research qualitative methods of content analysis are used.

Results: The results show that the students’ perspectives on sound evolved, as students managed to consolidate links between their everyday experience of sounds and the underlying science concepts as frequency, intensity and frequency spectrum. The authentic environment and the use of the smartphone’s applications were key factors for the success of the teaching experiment. The interaction with the activities shifted student’s conceptualizations closer to the scientific ones, by communicating every day sound experiences with their scientific interpretation.  相似文献

Education policy increasingly promotes action groups as a key strategy for student and/or staff participation in school improvement and whole-school health promotion. Such groups can coordinate multi-component interventions, increase participation and engagement, and enable local adaptations, but few process evaluations have assessed this. We evaluated fidelity, feasibility and acceptability of action groups as part of a trial of a whole-school intervention to reduce bullying and aggression and promote health in English secondary schools, which reported multiple health and educational impacts. Action groups involved students and staff, supported by external facilitators, and drew on data on student needs. They aimed to: coordinate implementation of restorative practices and a social and emotional competencies curriculum; review policies and rules; and enact local decisions to modify school environments. Our process evaluation used interviews, focus groups, observations and questionnaires to assess action groups’ fidelity, role in coordination, role in local adaptation, support from external facilitators and data on student needs, and acceptability in engaging members. Fidelity was high in the first two years but lower in the third year when external facilitators withdrew. Student needs data were perceived as useful, but views on external facilitators were mixed. Groups successfully reviewed policies and rules, planned activities and coordinated restorative practices, but were less successful in implementing the curriculum. Success was facilitated by the involvement of school leaders. Members reported high satisfaction and empowerment. Action groups are a promising strategy for leading whole-school health promotion. Implementation is supported by external facilitation, local data and involvement of senior managers.  相似文献

This study explores the impact of an urban ecology program on participating middle school students?? understanding of science and pro-environmental attitudes and behaviors. We gathered pre and post survey data from four classes and found significant gains in scientific knowledge, but no significant changes in student beliefs regarding the environment. We interviewed 12 students to better understand their beliefs. Although student responses showed they had learned discrete content knowledge, they lacked any ecological understanding of the environment and had mixed perceptions of the course??s relevance in their lives. Students reported doing pro-environmental behaviors, but overwhelmingly contributed such actions to influences other than the urban ecology course. Analyses indicated a disconnect between the course, the environment, and the impact on the students?? lives. Consequently, this suggests the importance of recognizing the implications of context, culture, and identity development of urban youth. Perhaps by providing explicit connections and skills in urban environmental programs through engaging students in environmental scientific investigations that stem from their own issues and questions can increase student engagement, motivation, and self-efficacy of environmental issues.  相似文献

Structuring job interviews is a method of decreasing bias and increasing the predictive validity of job performance, but research suggests that applicants can react negatively to structure (Chapman & Zweig, 2005) and that negative attitudes about selection tools can predict performance (Hausknecht, Day, & Thomas, 2004). The current exploratory study investigates how structuring the job interview in conjunction with priming the ethnicity and sex of the applicant, and in some conditions providing an explanation of the structure, affected post‐interview cognitive ability performance. Three levels of structure were randomly assigned. Those who experienced a structured interview without an explanation of its purpose scored lower than those who experienced an unstructured interview, but those who experienced a structured interview with an explanation of its purpose did not score lower than those who experienced an unstructured interview. Scores differed for females and Hispanics depending on the structure condition, but not in the same manner. Implications for recruitment, selection, and performance management are discussed.  相似文献

The current work examines children's sensitivity to rime unit spelling–sound correspondences within the context of early word reading as a way of assessing word‐specific influences on early word‐reading strategies. Sixty 6–7‐year‐olds participated in an experimental reading task that comprised word items that shared either frequent or infrequent rime unit correspondences. Retrospective self‐reports were taken as measures of strategy choice. The results showed that the children were more accurate in identifying word items that shared a common rime unit (consistent items) when compared with those containing infrequent rime units (unique and exception items). Moreover, while nonlexical (phonological) attempts were most frequently applied across all word types, these resulted in lower levels of accuracy, especially for the exception word items. The current data support the argument that children are increasingly sensitive to rime unit sound–spelling correspondences during the early stages of their word reading and the nature of these word‐specific orthographic representations shape their reliance on using particular lexical or non‐lexical‐based word‐reading strategies.  相似文献

The measurement community needs to better understand how to interact with the media to effectively disseminate important findings from educational testing efforts. To this end, the current paper will review media coverage of educational testing and related issues and elaborate on areas of concern and opportunities for improved communication between measurement professionals and the media. Common misinterpretations of test results and measurement concepts will be discussed and suggestions for the clearer presentation and explanation of such information will be offered. Also, practical advice and strategies for handling different types of interactions with the media will be provided. The implications of focusing on this topic in the measurement profession and the inherent public value of this focus are highlighted throughout the paper.  相似文献

Patterns of technology ownership and usage, as well as skills with and preferences for various technologies, affect the college experience (Educause 2012). Students at a commuter campus of a large Midwestern public university were surveyed about technology and the learning process: 94% of the respondents believed that technology had the potential to benefit learning and 85% thought it was central to their academic success. Students credited technology-enhanced courses with increased and more effective communication with instructors, the ability to better manage course activities and expanded opportunities for practice and reinforcement. Students’ prior experiences with a course management system affected their perceptions of the role of technology and their subsequent beliefs about the benefits of its use in their university courses. Implications for administrators who make decisions about faculty development, student retention and funding for technology-enhanced course offerings are discussed.  相似文献
