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.     

Balancing the Media

This paper outlines a ‘conversational framework’ for describing the essential elements of the learning process. The framework is used to elaborate the kinds of learning activities students need to carry out in order to arrive at a conceptual understanding of the topic they are studying. The framework is then applied to contrasting learning media: print, video, computer‐based tutorial and teacher‐student discussion, to determine which learning activities each is capable of supporting. These combinations of ‘multiple media’ are then compared with the new ‘multi‐media’ systems for their likely pedagogical benefits.     

Community support programme: support for Chinese trans* students experiencing genderism

Abstract

Previous research on school experiences has often focused on lesbian and gay students. Far fewer studies have examined trans* students’ experiences, especially with respect to community support. And none of this work has addressed relevant issues in an East Asian Chinese cultural context, where transgender equality has been a hotly debated issue in recent years, and prejudice towards members of this ‘invisible’ population still persists. This paper highlights the school experiences of trans* students based on a literature review of international, regional and Hong Kong publications. A case study analysis of one Hong Kong community support programme is used as an example to highlight the important role that this kind of work can play in filling a gap left by the formal education sector. Findings suggest that, given the influence of genderism and deficiencies of in school environments, community support services provided by non-government organisations can play a significant role not only in raising public awareness, but also in filling education and service gaps for sexual and gender minority students.     

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.     

The stimulus-response overshadowing phenomenon with VI versus FI schedules of reinforcement

Previous research has shown that response rates on a variable interval (VI) schedule of reinforcement decrease if a brief response-produced signal is given prior to reward. One explanation is that the signal overshadows the response because it is a better predictor of reinforcement. The S-R overshadowing effect does not occur with variable ratio (VR) schedules, however. Tarpy, Lea, and Midgley (1983) explained this fact by suggesting that the signal functions to enhance the salience of the temporal interval offset on the VI schedule (a characteristic not possessed by VR schedules), which then overshadows the response. In this experiment, the salience of the temporal interval was enhanced in another way: signaled or unsignaled reward was provided to rats responding on either a VI or fixed interval (FI) reward schedule. As predicted, rates were lowest for animals receiving signaled reinforcement on an FI schedule and highest for those receiving unsignaled reinforcement on a VI schedule.

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.     

Parental Identity and Its Relation to Parenting and Psychological Functioning in Middle Age

Objective. This article focuses on identity as a parent in relation to parenting and psychological functioning in middle age. Design. Drawn from the Jyväskylä Longitudinal Study of Personality and Social Development, 162 participants (53% females) with children (age 36), represented the Finnish age-cohort born in 1959. Parental identity was assessed at ages 36, 42, and 50. Results. In both women and men, parental identity achievement increased from age 36 to 42 and remained stable to 50. The level of parental identity achievement was higher in women than in men. Achievement was typical for women and foreclosure for men. Participants’ education, occupational status, and number of offspring were not related to parental identity status. As expected, parental identity achievement was associated with authoritative (indicated by higher nurturance and parental knowledge about the child’s activities) parenting style. No significant associations emerged between parental identity foreclosure and restrictiveness as an indicator of authoritarian parenting style. The diffused men outscored others in parental stress. Achieved parental identity was related to generativity in both genders and to higher psychological and social well-being in men. Conclusions. At present, many parenting programs are targeted to young parents. This study highlighted the importance of a later parenting phase at around age 40, when for many, the children are approaching puberty. Therefore, parenting programs and support should also be designed for middle-aged parents. Specifically men may need additional support for their active consideration and engagement in the fathering role.
