Peer interaction and the learning of critical thinking skills in further education students

A teaching programme is reported in which criticalthinking skills (in the sense of reasonedjustification of arguments; see Kuhn, 1991, 1993) weretaught. The principal aims of the study were todevelop, implement and evaluate a programme forteaching evidence-based justification to vocationaleducation students in Further Education colleges. Teaching was via modelling and peer-based critiquingexercises in the context of the students' projectwork. Eighty-four Further Education college studentsunderwent a 10-session teaching intervention whichdovetailed with their Additional Assessmentintegrative project work. Students took part inpeer-based exercises in which they learned to critiqueimaginary examples of project outlines and plans,followed by similar peer-based critiquing of eachothers' proposed projects. Analysis of the students'dialogues with each other indicated that they hadlearned the importance of justifying arguments, andcontent analysis of their written work indicated thatthey engaged in justification of their arguments to asignificantly greater degree than control groups. Several key variables in the dialogues correlatedpositively with justification in the written work,suggesting that the dialogue had impacted on thewritten work. However, justification tended to be ofa weak kind (using anecdotes or experience-basedgeneralisations), and strong (i.e. formalresearch-based) evidence remained relativelyinfrequent and sometimes inappropriately used. Apsychometric test of general critical thinking skillsshowed no evidence of transfer of learning.     

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.     

Text editing in chemistry instruction

In two experiments, differential performance onchemistry problems was obtained for twotraining strategies: text editing andconventional problem solving. Text editingrequires students to scan the text of problemstatements and specify whether it providessufficient, missing or irrelevant informationfor solution. It was hypothesized that textediting, which emphasizes gaining familiaritywith schematic knowledge, would lead to higherachievement than conventional problem solving.Experiment one indicated that text editing wassuperior to conventional problem solving inlearning to solve molarity and dilutionproblems. In particular, students who weretrained in text editing skipped someintermediate steps while solving molarityproblems. In contrast, using stoichiometryproblems, experiment two showed that students whowere trained in text editing performed worsethan students given conventional problems tosolve. An error analysis suggested that becauseof its failure to direct students' attention tothe coherent problem structure in the firstinstance, text editing has no advantage overconventional problem solving in the domain ofstoichiometry problems. It was concluded thatthe suitability of a text editing trainingstrategy depends on the learning materials.     

Structural Change,Leadership and School Effectiveness/Improvement: Perspectives from South Africa

This article comments on leadership within mainstream literature on school effectiveness/improvement, where it is almost always considered to be a factor of change. The article argues that systemic school improvement, particularly for disadvantaged children, is inextricably linked to wider social, economic and political conditions—in South Africa’s case, the political transition from apartheid to democratic government. These structural conditions and specific historical contexts are often glossed over in models of school effectiveness/improvement. Through an analysis of dysfunctional and resilient schools as a legacy of apartheid, and of the slow reconstruction of education in the post‐apartheid period, the article argues for the importance of political legitimacy and authority in school improvement. The article concludes by suggesting that states in transition require a different theoretical lens in order to understand the impact of wider social changes on schools. In such societies, the establishment of legitimacy and authority is a precondition for sustainable effectiveness and improvement, and this has implications for theorising the role of leadership in school change more generally.     

Parenting Style as a Moderator for Students’ Academic Achievement

Parenting styles have always been a crucial factor in influencing all aspects of a person??s development. The purpose of this study is to test the structural equation model of academic achievement among the students using parenting styles as a moderator. The sample comprised 493 students from eight schools. Parenting styles are determined using the Parental Authority Questionnaire (Buri in J Pers Assess 57:110?C119, 1991). Academic achievement is measured based on the students?? performance in the Lower Secondary Assessment. Data were analyzed using structural equation modelling. Results demonstrated that model of authoritative and model of authoritarian fit the data of this study well. Both authoritative and authoritarian parenting styles are the most common practice of the parents. Parenting styles have been found to be a moderator of this study. The results indicated that parenting styles moderated the effect of academic self-concept on academic achievement. The impact of academic self-concept on academic achievement is found to be greater for the authoritative than the authoritarian parenting style.     

Multilingual Information Access (MLIA) Tools on Google and WorldCat: Bi/Multilingual University Students’ Experience and Perceptions

Abstract

This article reports on the results of an exploratory user-centered study that examined how technological advancements in natural language processing (NLP) such as the availability of multilingual information access (MLIA) tools impact the information searching behavior of bi/multilingual academic users. Thirty-one bi/multilingual students participated in a controlled lab-based user experiment in which they carried out two assigned tasks each on Google and WorldCat for a total of four tasks, and then completed a post experiment questionnaire. The captures from the experiment showed 86.7% of the participants using multilingual information access tools. Further analyses of the captures also showed that participants were more likely to use MLIA tools when the instructions for the task were stated in their native language. An independent samples t-test revealed that participants spent less time on their searches when they used MLIA tools. The study revealed considerable diversity in the information searching behavior of the participants, even within the same pair of languages, and even for the same user. Diversity was noted for instance, on which tasks MLIA tools were used and in how these tools were used. User-centered designed, personalized multilingual information retrieval (PMLIR) models could hold promise for best representing the information searching behavior of bi/multilingual users.
