Science Teachers’ Perceptions: Similarities and Differences in the U.S., England,Singapore and Japan

The prospect of using internationally generated comparative data, augmented with practice patterns, to provide useful information from which countries can learn from each other, is gaining acceptance from the increasing popularity of such an approach (Stigler and Hiebert, 1999). Using the survey data from TIMSS we examine the beliefs of teachers in the U.S., England, Singapore and Japan, and find little national variation in many teachers’ perceptions of core practices in science teaching, indicating that science teachers the world over share the same common core practices. However, there is one key difference among their practices, which signals a departure in the way teachers in Japan and Singapore operate vis‐à‐vis those in the U.S. and England. This key difference is attributed to cultural differences in the U.S. and England, when compared to Japan and Singapore.     

Training early childhood teachers for sustainability: towards a ‘learning experience of a different kind’

In this study, we discuss findings from a small-scale project evaluating an in-service teacher training programme focused on ‘perspective transformation’ in early childhood education and education for sustainability (EfS). A bespoke professional development programme was developed for Turkish early childhood teachers, based on a variety of Mezirowian-inspired adult education activities. Data were gathered using a mixed method research design, from 24 early childhood educators, through learning diaries, a Learning Activities Survey and follow-up interviews. Initial findings illustrate the range of transformations possible in the teachers’ perspectives during and after the training workshops. Influential factors in facilitating perspective transformation are shown to be the content, structure and sequencing of the training, and peer support. We conclude that transformative learning techniques offer a viable framework for engaging practicing early childhood teachers with EfS and also discuss implications for teacher preparation in both areas.     

Computers and the emancipation of students: giving control to the learner

The paper considers two basic models of the teaching-learning process, described as the didactic and the communication model. These are applied to Computer Assisted Learning (CAL) in order to demonstrate that CAL has generally embodied a didactic model of teaching and learning. This imposes an unnecessary restriction on the student's freedom to choose their (Note 1) learning style, and the paper discusses how it is possible for CAL to support a less didactic model and to give more control to the student.

What's in a name? A comparison of methods for classifying predominant type of maltreatment

OBJECTIVE: The primary aim of the study was to identify a classification scheme, for determining the predominant type of maltreatment in a child's history that best predicts differences in developmental outcomes. METHOD: Three different predominant type classification schemes were examined in a sample of 519 children with a history of alleged maltreatment. Cases were classified into predominant maltreatment types according to three different schemes: Hierarchical regression analyses examined whether the HT, SFT, and EHT type classifications contributed to prediction of child behavior problems, trauma symptoms and adaptive functioning. RESULTS: After controlling for demographic factors, the HT definitions predicted four outcomes, while the SFT definitions predicted three, and the EHT classifications contributed to the prediction of five child outcomes. The co-occurrence of multiple types of maltreatment was robustly related to outcomes. However, the HT and SFT classifications predicted outcomes even after accounting for the co-occurrence of multiple maltreatment subtypes. CONCLUSION: A classification scheme that differentiates between type combinations and single maltreatment types may have the greatest predictive validity. Over and above knowing about co-occurrence of maltreatment sub-types, it is important to understand what type, or constellation of types, of maltreatment have been alleged in a child's history.     

Environmental and Genetic Variance in Children's Observed and Reported Maladaptive Behavior

The genetic and environmental contributions to children's maladaptive behavior are assessed in a sample of 154 twin pairs (77 MZ twin pairs and 77 DZ twin pairs), who range in age from 6 to 11 years. To bridge the strengths of behavioral genetic methods and environmental assessment techniques, we use a multimethod, multimeasure approach to data collection, and analyze the data using behavioral genetic modeling techniques. Results indicate that genetic variation accounts for a majority of the variance in parent-reported child maladaptive behavior (average = 62%). One parent-report measure also suggests a smaller, significant contribution of shared environmental variance. In contrast to the parental ratings, the observational coding and global impressions of parent-twin interactive behavior suggest that shared environment is the primary source of variance accounting for parent and child maladaptive behavior. This is due, in part, to the direct influence one's interactive partner has on the expression of maladaptive behavior in an interactive setting. When controlling for the co-participant's behavior, genetic variation increases and shared environmental variation decreases.
