Effect of Twinning on Chinese and English Vocabulary Knowledge

Vocabulary knowledge was tested in a native (Cantonese-Chinese) and foreign (English) language in 150 twins and 150 singletons aged 6–11 years, matched on age, gender, grade level, nonverbal intelligence, parents’ education, family income, and number of siblings and household members. The singletons clearly outperformed the twins on the native vocabulary, but this “twinning effect” was much less noticeable for the foreign vocabulary. The effect on English vocabulary was further reduced after exposure to English at home was controlled. Given that these participants learned most of their English in school rather than home, the present findings support the notion that the twinning effect is associated with increased competition for family interaction in twins compared with singletons.     

Dynamic mental models in learning science: The importance of constructing derivational linkages among models

We present a theory of learning in science based on students deriving conceptual linkages among multiple models which represent physical phenomena at different levels of abstraction. The models vary in the primitive objects and interactions they incorporate and in the reasoning processes that are used in running them. Students derive linkages among models by running a model (embodied in an interactive computer simulation) and reflecting on its emergent behaviors. The emergent properties they identify in turn become the primitive elements of the more abstract, derived model. We describe and illustrate derivational links among three models for basic electricity: a particle model, an aggregate model, and an algebraic model. We then present results of an instructional experiment in which we compared high school students who were exposed to these model derivations with those who were not. In all other respects, both groups of students received identical instruction. The results demonstrate the importance of enabling students to construct derivational linkages among models, both with respect to their understanding of circuit theory and their ability to solve qualitative and quantitative circuit problems. © 1999 John Wiley & Sons, Inc.

Scientific Modeling for Inquiring Teachers Network (SMIT’N): The Influence on Elementary Teachers’ Views of Nature of Science, Inquiry, and Modeling

This paper summarizes the findings from a K-6 professional development program that emphasized scientific inquiry and nature of science within the theme of scientific modeling. During the 2-week summer workshop and follow up school year workshops, the instruction modeled a 5-E learning cycle approach. Pre and posttesting measured teachers’ views of nature of science, inquiry, and scientific modeling. Teachers improved their views of nature of science (NOS) and inquiry by including scientific modeling in their definitions of how scientists work, the empirical nature of science, and the role of observations and inferences in science. Their definitions of science expanded from a knowledge-based orientation to a process-based orientation. Teachers added the use of mathematical formulas to their views of scientific modeling. Using scientific modeling as the central theme was effective in providing positive influence on teachers’ views of inquiry and NOS.     

Gender and Management in HEIs: Changing organisational and management structures

This paper reports on the second phase of a multi-country study examining cross cultural perspectives of gender and management in Higher Education Institutions (HEIs). It examines the broader labour market context and legislative frameworks for higher education in each country and then analyses the literature on women in university management. The paper presents the findings of research with male and female senior managers about their perceptions of women as HEI managers within changing organisational and management structures. It concludes that although HEI’s are now largely aware of barriers to women getting into and on in senior management, they have not addressed the organisational structures and cultures that perpetuate this inequity.

     

Connecting religion and teacher identity: The unexplored relationship between teachers and religion in public schools

It is increasingly acknowledged that for individuals to participate in a pluralistic and democratic society, they must understand religious conviction and difference. In educational literature, the discussion surrounding education and religion focuses on the implications for students. It is important to consider what this may mean to the teachers, as teachers directly influence student learning. This article uses literature on religion, multiculturalism, teacher identity, and popular culture to connect teachers' private religious identifications to their professional identities in public school classrooms. It supports future research in this area and provides a theoretical framework for subsequent studies.     

Simultaneous Delivery of a Face-to-Face Course to On-Campus and Remote Off-Campus Students

The purpose of this case study was to determine the feasibility of delivering a course on-campus and in real time, simultaneously transmitting it to students who were remotely accessing the same course. In future years, it is anticipated that universities will have inadequate physical facilities to meet the demands of an increasing student population. Additionally, with warnings of impending pandemics, universities need to be prepared to deliver courses in alternative ways to ensure continuity of instruction. Thus, this pilot project was designed to deliver a course to a large section of students while also allowing off-campus students access to the course in real time. The planning and delivery of the course is described, including the technology used, the support provided by the university and technology support staff, the course that was used for the pilot project, and how students were selected to participate as the off-campus students. The perspectives of the instructor, teaching assistant, students (both on- and off-campus), and technology support personnel are summarized.     

Loneliness,friendship quality and the social networks of adolescents with high‐functioning autism in an inclusive school setting

By definition, children with autism have poor peer relationships despite age and ability. When children enter adolescence, social problems typically worsen and feelings of loneliness and isolation may emerge. Thus, the overarching goal of the current study is to examine the social–emotional relationships of adolescents with autism and their typically developing (TD) classmates. Participants included 20 adolescents, 7 adolescents with autism and 13 TD classmates. All participants were enrolled in a drama class at a regular education high school in the Los Angeles area. Results indicate that adolescents with autism experienced significantly more loneliness than their TD classmates, had significantly poorer friendship quality in companionship and helpfulness, and had significantly lower social network status than their TD classmates. In addition, 92.4% of TD adolescents had secondary or nuclear social network centrality, which means that those adolescents were significantly connected and recognised in their classroom social structure although 71.4% of the adolescents with autism were either isolated or peripheral in their classroom. These findings imply that although inclusion in regular classrooms may allow adolescents with autism to be involved in the social structure of their classroom, they experienced more loneliness, poorer friendship quality and social network status as compared with their classmates. These results suggest that, perhaps, more intensive social skills' interventions that focus on friendship development are needed in adolescents with autism.     

Seeing one another as “other”

In this paper, the authors discuss two complementary life history research projects investigating prospective teachers' identities in relation to their race and social class. Drawing on the experiences of one student from each study, they show how both whites and students of color primarily thought about one another as “others”—people who fundamentally differed from one another and whom they understood through preconceived ideas about a group. The authors draw on a Bakhtinian notion of how a “surplus of sight” enables one to develop understandings of an “other” and also of oneself.
