Comparing Digital Apples and Oranges: A Comparative Analysis of e-Books Across Multiple Platforms

This session reported the findings of a comparative analysis of how e-books are represented across multiple platforms. In this session, the presenters shared the results of a study that examined how a sample of academic e-books are represented across different platforms. Topics of analysis included: the inclusion of various metadata, the visual presentation of e-book content, and variations in search results. This presentation also focused on the similarities and differences between e-book representation and what impact these various representations might have on users of academic e-books.     

Winning the battle and losing the war: Examining the relation between grade retention and dropping out of high school

The aim of this investigation is to provide a comprehensive review of dropout research that examines grade retention within both associative and predictive models. A systematic review of seventeen studies examining dropping out of high school prior to graduation demonstrates that grade retention is one of the most powerful predictors of dropout status. The discussion addresses the discrepancies among the perspectives of many educational professionals regarding the effectiveness of grade retention and deleterious long‐term correlates. The transactional model of development is presented, which emphasizes developmental trajectories over time, in order to facilitate the interpretation of the association between grade retention and school withdrawal. Educational professionals, teachers, researchers, parents, and policymakers considering the efficacy of grade retention are encouraged to consider the implications of these findings. © 2002 Wiley Periodicals, Inc.

Learning From Video: A Meta-Analysis of the Video Deficit in Children Ages 0 to 6 Years

Young children often learn less from video than face-to-face presentations. Meta-regression models were used to examine the average size of this difference (video deficit) and investigate moderators. An average deficit of about half of a standard deviation was reported across 122 independent effect sizes from 59 reports, involving children ages 0–6 years. Moderator analyses suggested (a) the deficit decreased with age, (b) object retrieval studies showed larger deficits than other domains, and (c) there was no difference between studies using live versus prerecorded video. Results are consistent with a multiple-mechanism explanation for the deficit. However, the analyses highlighted potential quality and publication bias issues that may have resulted in overestimation of the effect and should be addressed by future researchers.     

A Model of the Effects of Perceived Parent and Peer Support on Adolescent False Self Behavior

A model linking 3 perceived support variables, namely, level of support, quality of support (unconditional or conditional), and hope about future support, to false self behavior (acting in ways that are not the "real me") was hypothesized. Both parent and peer support were examined. The best fitting model for the parent and peer data revealed that perceived quality and level of parent support predict hope about future parent support, which in turn predicts false self behavior. Adolescents' motives for engaging in false self behavior were also examined. Those whose reported motives were hypothesized to be the most clinically debilitating (devaluation of the self) reported the most negative outcomes (depressed affect, low self-worth, hopelessness, and less knowledge of the true self). In contrast, adolescents citing the developmentally normative motive of role experimentation reported the most positive affect, highest self-worth, greatest hopefulness, and most knowledge of true self. Those reporting that they engaged in false self behavior to please, impress, or win the approval of parents and peers had intermediate scores on the depression, self-worth, hope, and knowledge of true self measures. Discussion focused on the potential causes and consequences of false self behavior.     

Abusive head trauma in Maine infants: medical,child protective,and law enforcement analysis

OBJECTIVE: To collect and compare the results of medical, child protective, and law enforcement evaluation of a sample of Maine children who were victims of abusive head trauma (AHT) in order to describe the clinical and evaluative characteristics as they relate to victims, families and perpetrators of such trauma and to improve the professional response to AHT in Maine.METHOD: Retrospective chart review of medical, child protective, and law enforcement records of all AHT victims admitted to two tertiary care hospitals in Maine or seen by the state medical examiner from 1991 to 1994.RESULTS: Nineteen children (age range 2 weeks to 17 months) were identified as victims of AHT (out of a total of 94 head trauma admissions) accounting for 20 hospitalizations during the study period. There was a history of prior injury in 30%, history of prior medical evaluations for possibly abuse related problems in 65%, while, on presentation, 75% had evidence or history of prior injury. The hospitals notified child protective services (CPS) in all 20 cases and correctly identified abuse in 18 (90%). Parental risk factors for abuse identified in CPS records included substance abuse (53%), domestic violence (42%), criminal history (32%), unrealistic expectations (42%), and attachment problems (32%). However, risk factors were inadequately assessed in 53% of homes. Law enforcement identified a likely perpetrator in 79% of cases and in the majority the identified suspect was the father. In the 15 cases where a perpetrator was identified by law enforcement, that person was alone with the child at symptom onset in 14 (93%).CONCLUSIONS: The medical response, at least at the inpatient level, was generally well done with regard to suspicion and reporting. Cases are possibly being missed at the outpatient level. Child protective risk assessment was limited overall yet in a third of the homes where AHT occurred, few if any risk factors were present to aid in identification and prevention. Law enforcement results suggest that a primary suspect for AHT is the caretaker alone with the child at the time of symptom onset.     

Becoming Poetry Teachers: Studying Poems Through Choral Reading

Abstract

The poet, Seamus Heaney, argues that transformations for both teachers and students may be engendered through recognising the connections and distinctions between the language of poetry and the language of everyday life. This article explores some of the ways in which choral reading of poetry, using multiple voices like musical instruments, may change student teachers’ perceptions of poetry. Five small groups of Secondary English student teachers on an initial teacher education Postgraduate Certificate of Education (PGCE) course constructed choral readings, each group working with a different poem. During the session, they wrote journal entries about how creating the readings and listening to other people led them to think differently about studying poetry with students in the classroom as future secondary English teachers. Several months later, a small voluntary group met to recollect the session and consider more critically the potential of choral reading as one possible approach to teaching poetry.     

Classroom structuration and the development of social representations of the curriculum

The study drew on Bernstein's theory and Moscovici's theory of Social Representations to investigate how children in classrooms with different types of structuration developed social representation of the curriculum. Comparable case studies were carried out in schools chosen to reflect three types of pedagogy according to Bernstein's typology. Twelve classrooms took part and ethnographic investigations were employed to compile a typology of recognition and realisation rules to map the range and type of curriculum structuration in each. Children's representations of the curriculum were investigated through specially designed tasks. Findings showed that as children gained experience of schooling they constructed more elaborate social representations of the curriculum regardless of the pedagogic mode and that classroom structuration became a feature of the junior rather than the infant children's representations. Older children in classrooms with performance pedagogies had two classifications for recognising classroom culture, while those in classrooms with mixed and competence pedagogies did not.     

A New Method for Evaluating Knowledge,Beliefs, and Neuromyths About the Mind and Brain Among Italian Teachers

Teachers often face situations that require them to apply knowledge about the mind and brain to education. Past studies have indicated that even if teachers show interest in cognitive neuroscience, they show high rates of adhesion to neuromyths. In the most commonly used questionnaire, however, respondents do not compare neuromyths and correct information based on neuroscience. The present study proposes a multiple‐choice questionnaire that presents scenarios occurring in school. The most commonly used and the new questionnaire were administered to 174 Italian teachers. In the most commonly used questionnaire, teachers generally had the same likelihood of accepting neuromyths as the literature reports. In the new questionnaire, the levels of both general knowledge and beliefs about neuromyths were significantly lower. Moreover, it suggests that teachers' adhesion to neuromyths in realistic situations does not match their explicit beliefs. Thus, the present research proposes that the use of questions based on feasible scenarios is a useful method to assess neuromyths.
