Problematic school absenteeism in youth has long been a complex and vexatious issue for psychologists, educators, and researchers from other disciplines. An examination of problematic school absenteeism from different perspectives over many decades has led to poor comparability across publications, policies, and assessment and intervention protocols. This article briefly reviews literature from psychology, social/criminal justice, and education to outline important factors that influence school absenteeism. An interdisciplinary model is then proposed with an emphasis on common terminology and definitions, comprehensiveness with respect to proximal and distal influences, fluidity and flexibility to account for rapid changes in this population, and user-friendliness to generate suggestions regarding assessment and intervention. Implications of the model are then drawn for professional practice and public policy, including recommendations for individual and systemic intervention at multiple levels of risk and severity.  相似文献

OBJECTIVES: To understand the features of child abuse/neglect (CA/N) allegations in cases with emotional maltreatment (EMT) allegations, as well as the features of the EMT allegations themselves, and to describe any associations of EMT with distinct impairments of children's behavior, emotion and functioning. METHOD: The sample consisted of 806 high-risk children, 545 with one or more maltreatment reports to CPS. The Maltreatment Classification System was used to record the number and severity levels of maltreatment allegations, which compared cases with and without EMT. Multiple regression analyses were conducted using 10 outcome scales from the Child Behavior Checklist, Vineland Screener, and Trauma Symptom Checklist. Successive blocks of predictor variables included demographics, maltreatment classification variables, maternal and family characteristics, and study site. RESULTS: When there were allegations of EMT as well as CA/N in a CPS case-record (by age 8), the CA/N allegations tended to be either more frequent or less severe than those kinds of allegations in cases without EMT. When neglect was alleged to occur with EMT, neglect allegations outnumbered allegations of EMT. However, when sexual abuse allegations were accompanied by EMT allegations, there were more EMT allegations than sexual abuse allegations in the cases. Higher severity ratings for EMT allegations than for physical abuse occurred when cases included any abuse. Distinctive effects of EMT subtypes were found between problems of safety/restriction and self-reported anger symptoms, and between problems of self-esteem/autonomy and posttraumatic stress. CONCLUSION: Differences exist between the CA/N allegations in cases with and without EMT. Having few cases containing only EMT allegations made it difficult to assess distinctive harm associated with EMT. Certain types of EMT allegations were associated with increases in children's anger and posttraumatic stress.  相似文献

The development of children's ideas about others' difficulties in learning   总被引:1,自引:0,他引:1  
In this paper, Professor Ann Lewis, of the School of Education, University of Birmingham, reviews the literature and current research on pupils' perceptions of others' difficulties in learning. She focuses, in particular, on three strands: children's perceptions about other people and their traits; children as 'naïve' biologists, attempting to explain growth and development in others; and children's responses to and use of cues based on achievement and ideas about ability. In a wide-ranging discussion, this article explores work on theory of mind and notes the different ways in which children explain learning difficulties in others at various ages. In her conclusion, Professor Lewis makes three key points: there is a need to supplement experimental work in this area with good quality, classroom-based studies; more effort should be devoted to finding ways of accessing children's views and perceptions in authentic and reliable ways; and staff working in inclusive classrooms are ideally placed to contribute to the development of research in this area.  相似文献

In this paper, I reconstruct Alasdair MacIntyre's aretaic, practical philosophy, drawing out its implications for professional ethics in general and the practice of teaching in particular. After reviewing the moral theory as a whole, I examine MacIntyre's notion of internal goods. Defined within the context of practices, such goods give us reason to reject the very idea of applied ethics. Being goods for the practitioner, they suggest that the eudaimonia of the practitioner is central to professional ethics. In this way, MacIntyre's moral theory helps us recover the untimely question, how does teaching contribute to the flourishing of the teacher?  相似文献

In September 2000, new qualifications for 16–19 year olds, known as Curriculum 2000, were introduced in England, Wales, and Northern Ireland with the aim of broadening the advanced level curriculum. It was left to schools, colleges, and their learners, however, to decide how these new qualifications would be used to build learner programmes of study. In this voluntarist context, the views and actions of learners have been an important factor in determining the course of the reforms. This article, which is based primarily on a study of 42 learners in a school/college consortium in the south west of England, provides a chronological account of learner experiences of these reforms during their first 2 years of implementation. The consortium discussed here offered a high‐volume study programme similar in size and content to those being proposed by the Tomlinson Working Group on 14–19 curriculum and qualifications reform in England. Learners found their expanded programmes onerous, due in part to the nature of the new qualifications and in part to the context of their implementation. The article concludes by identifying a number of policy lessons for 14–19 reform arising from this research.  相似文献

Abstract

The purpose of this study was to examine the relationship between motor proficiency and body mass index (BMI) in preschool children. Thirty-eight children ages 4–6 years had their BMI calculated and were assessed using the Movement Assessment Battery for Children-2 (MABC-2; Henderson, Sugden, & Barnett, 2007). These data were analyzed in two ways. The correlation between BMI and MABC-2 percentile ranks was calculated. Next, the groups were subdivided based on BMI status (high, M = 85.5; medium, M = 49.8; low, M = 10.8), and compared using t tests to determine if differences existed in MABC-2 percentile ranks. No significant relationship existed between MABC-2 and BMI percentile ranks (r = -.237). However, significant differences in MABC-2 percentile ranks existed between high and low (p = .042), and high and medium (p = .043) groups. These results suggest that preschool children classified as overweight or obese may have lower motor proficiency than their normal weight and under weight peers. This study indicates there is a direct relationship between motor proficiency and BMI in the preschool population.  相似文献

The aim of this study is to determine changes in sedentary behaviour in response to extensive aerobic exercise training. Participants included adults who self-selected to run a marathon. Sedentary behaviour, total activity counts and physical activity (PA) intensity were assessed (Actigraph GT3X) for seven consecutive days during seven assessment periods (?3, ?2, and ?1 month prior to the marathon, within 2 weeks of the marathon, and +1, +2, and +3 months after the marathon). Models were fitted with multiple imputation data using the STATA mi module. Random intercept generalized least squares (GLS) regression models were used to determine change in sedentary behaviour with seven waves of repeated measures. Results: Twenty-three individuals (mean?±?Sx: 34.4?±?2.1y, 23.0?±?1.9% fat, 15 women, 8 men) completed the study. Marathon finishing times ranged from 185 to 344 minutes (253.2?±?9.6 minutes). Total counts in the vertical axis were 1,729,414 lower one month after the race, compared with two months prior to the race (peak training). Furthermore, counts per minute decreased by 252.7 counts·minute?1 during that same time period. Daily sedentary behaviour did not change over the seven assessment periods, after accounting for age, gender, per cent body fat, wear time, marathon finishing time, and previous marathon experience. This prospective study supports the notion that PA and sedentary behaviours are distinct, showing that sedentary behaviour was not impacted by high levels of aerobic training.  相似文献
