The incidence of infant physical abuse in Alaska

OBJECTIVES: To determine the incidence of and risk factors associated with infant (< 1 year of age) physical abuse in Alaska. METHODS: A population-based retrospective cohort study for the 1994-2000 resident birth cohort was conducted by linking data from birth certificates, Child Protective Services, a statewide hospital-based trauma registry, hospital discharge data, and the Alaska Infant Mortality Review (including death certificates). The main outcome measures were the incidences of overall physical abuse and abuse resulting in hospitalization or death. A case of child abuse was defined as an instance of substantiated physical abuse to an infant identified in the Child Protective Services database or an infant death with homicide identified on the death certificate as the manner of death. RESULTS: During the 7-year study period, there were 70,842 births and 325 cases of physical abuse including 72 that led to hospitalization (n = 58), death (n = 4), or both (n = 10); respective incidences for all abuse and abuse leading to hospitalization or death were 4.6 and 1.0 per 1000 live births. Following multivariate analyses, the risk factors with the highest population attributable risks were maternal or paternal education < or = 12 years, unmarried mother, and maternal prenatal substance use. To determine if the study methodology was likely to have missed cases of severe abuse, we examined information for all 216 infants hospitalized for trauma during the study period who did not have identification of abuse in one of the study databases; of these, at least 39 had injuries inconsistent with the reported mechanism (a long bone or skull fracture that reportedly resulted from a fall of less than 3 feet or from a caretaker's arms or for which the caretaker denied a history of trauma). Conclusions: Alaska has one of the highest documented infant physical abuse incidences reported in the literature and abuse is associated with potentially modifiable-primarily social-risk factors. Despite this high incidence, substantial under-reporting of hospitalized cases likely occurs.     

Associations among preservice teachers’ psychological traits and classroom performance ratings

Abstract

Educational theorists and researchers have often overlooked potential links between successful teaching and a teachers personal qualities. This investigation explored associations among three psychological characteristics and classroom performance ratings of prospective teachers. Fifty‐three students enrolled in a teacher education program participated in the study. The students were assessed on personality style, creative thinking, motivation, and classroom performance competency during student teaching. Correlational statistical analysis found significant relationships among three creativity measures and ratings of preservice teachers’ classroom performance. Further, regression analysis revealed originality, one subscale of creativity, was a significant predictor of effective student teaching. Findings indicate that creative constructs may have potential value in assessing teacher education candidates.     

Differentials of a State Reading Assessment: Item Functioning, Distractor Functioning, and Omission Frequency for Disability Categories

Large data sets from a state reading assessment for third and fifth graders were analyzed to examine differential item functioning (DIF), differential distractor functioning (DDF), and differential omission frequency (DOF) between students with particular categories of disabilities (speech/language impairments, learning disabilities, and emotional behavior disorders) and students without disabilities. Multinomial logistic regression was employed to compare response characteristic curves (RCCs) of individual test items. Although no evidence for serious test bias was found for the state assessment examined in this study, the results indicated that students in different disability categories showed different patterns of DIF, DDF, and DOF, and that the use of RCCs helps clarify the implications of DIF and DDF.     

The Relationship of the World Wide Web to Thinking Skills

As access to the WWW increases in schools and classrooms it is vital for educators at all levels to examine closely its potential roles in learning. Much emphasis has been placed upon making the WWW available without enough emphasis on methods of using it so students will benefit from instruction based upon it. A continuing goal of modern pedagogy is to help students move beyond the lower order cognitive domain, knowledge and comprehension, to higher order thinking skills: application; analysis;, synthesis; and evaluation. Students also need critical thinking skills. These skills are necessary for dealing with the demands of the future information society, which will be even more complex and demanding than at present. In order to foster the skills mentioned above, teachers are urged to provide learning environments that are learner-centred, authentic, problem-based and collaborative. Les relations entre le World Wide Web et les aptitudes des pensées. Comme l'accès au WWW s'accroît dans les écoles et les classes il est vital que les enseignants À tous niveaux examinent de près son rÔle potentiel en éducation. On a mis beaucoup l'accent sur les possibilités d'accès au WWW sans mettre assez l'accent sur les méthodes d'emploi par les étudiants de facon À ce qu'ils puissent bénéficier de l'instruction qu'il permet. Un objectif constant de la pédagogie moderne est d'aider les étudiants À dépasser le domaine cognitif limité. le savoir et la compréhension vers des aptitudes de pensée d'un ordre supérieur : applications, analyses, synthèses et évaluations. Les étudiants ont aussi besoin de pensée critique - ces aptitudes sont nécessaires pour faire face aux demandes de la future société de l'information, qui sera encore plus complexe et exigeante que maintenant. De facon À favoriser les aptitudes mentionnées ci-dessus , il faut que les enseignants fournissent les environnements éducatifs qui sont centrés sur l'apprenant, authentiques, basés sur la résolution de problèmes et la collaboration. Der Zusammenhang zwischen dem World Wide Web und den Denkfähigkeiten. Mit den wachsenden Zugängen an das WWW in Schulen und Klassenräumen wird es für Lehrer auf allen Ebenen immer dringender ihre zukünftige Rolle im Unterricht zu überdenken. Es wurde sehr viel Wert auf die Verfügbarkeit des WWWs gelegt, ohne jedoch auf Anwendungsmöglichkeiten zu achten damit die Lernenden von einem auf dem Web basierenden Unterricht profitieren. Ständiges Ziel moderner Pädagogik ist, Studenten zu helfen, über die untere Stufe des kognitiven Bereichs, Wissen und Verständnis, auf eine höhere Stufe des Denkprozesses zu gelangen: nämlich Anwendung, Analyse, Synthese und Bewertung. Schüler brauchen auch kritisches Denken. Diese Fähigkeiten sind notwendig im Umgang mit den Anforderungen der zukünftigen Informationsgesellschaft, die noch komplexer und schwieriger als die jetzige sein wird. Um diese Fähigkeiten zu fördern müssen Lehrer Lernumfelder schaffen, die sich am Studenten orientieren, authentisch sind, auf Problemlösungen basieren und collaborativ sind.
