The purpose of this study was to construct and study the impact of a research-based sequence for teaching the concept of modelling to seventh-grade science students. We identified students' notions of models and the aspects of school science to be addressed regarding the model concept, which were then taken into account when we planned the…

This article proposes a model that integrates some of the determinants of scholastic judgment. The model is based on the assumption that a teacher's judgment in a particular discipline is influenced by different variables: the pupil's actual performance in the discipline, his/her actual performance in other disciplines (halo effect), the average…

This study describes the learning of researchers who engage in mathematics teacher education as an integral part of their practice. As teacher educators working with teachers on the subject of proportional reasoning, the authors reflected on teachers solutions to a standard problem and analyzed answers that would conventionally be considered…

The author believes that information technologies are powerfully heuristic in addressing one of education's deepest ambitions. Following Engelbart's paradigm, he sees these technologies as augmenting human intellect, not simply because they permit high-speed calculations but also because they externalize our own cognitive processes in a way that…

We further evaluated the Virtual Lecture Hall (VLH) (Cramer, Collins, Snider, & Fawcett, in press), an instructional computer-based platform to deliver PowerPoint slides threaded with audio clips for later review. Students from either an in-class or online section (ns = 810 and 74 respectively) of introductory psychology had access to live…

In this article, the author describes his "Business German" course. His course sought to narrate a dialectic of agency and institution. He started by asserting a distinction between the intending subject--with its plural desires, interests, and identifications--and the world it acts in, through and upon. This distinction between acting subject and…

Background: Sport Education (SE) and Teaching Games for Understanding (TGfU) are two curriculum models that were developed to help students participate in fair and equitable ways and challenge their thinking beyond the replication of techniques and skills. Given that the general aim of both models is to employ more democratic pedagogies and…

Typically, guidelines for design of interactive multimedia systems have been based on intuitive beliefs of designers rather than being founded on relevant research and theory. As advances in technology create new opportunities for education, it is important to use a range of theoretical perspectives to optimize use of new technology in teaching…

In 1980, the U.S. Congress charged the National Science Foundation (NSF) with a mission to lead development of science, technology, engineering, and mathematics (STEM) for all of its citizens. Joseph Bordogna, deputy director of NSF, reaffirmed the agency's commitment to the mission when he stated that NSF needs to broaden participation in the…

In this article, the author discusses African American researchers' perspectives on the experiences, impact and success of Black teachers with Black students in public schools. This study builds on an earlier study that focused specifically on these researchers' insights about the impact of the "Brown versus the Topeka Board of Education" decision…

This article examines some of the social, technical, and economic issues encountered in the implementation of an educational technology at an Australian regional university. Reference is made to the implementation of the videoconferencing network at Central Queensland University (CQU). In late 1996 when the implementation process was completed the…

To investigate factors influencing gifted early adolescent girls' career orientation and career aspirations in both the USA and Germany, the associations between giftedness, agentic characteristics, gender role attitudes, maternal characteristics, and the mother-daughter relationship were examined in 63 young adolescent girls. Additionally, two…

Mental models of metallic bonding held by learners from three academic levels, secondary school (year 12), undergraduate, and postgraduate, were probed using semistructured interviews including the use of Interviews-About-Events focus cards depicting metallic properties and cards containing depictions of models from curriculum material. The…

This study of 231 regulated family child care providers proposed a theoretical model to explore the effects on quality of: (1) provider level of general education; (2) provider degree of intentionality; (3) provider training and experience in family child care; (4) provider use of support services; and (5) provider work environment. Hierarchical…

Predictions about processes linking gender to students' choices of advanced courses were derived from the internal/external frame of reference (I/E) model and expectancy value (EV) theory. The predictions were tested for the domains of mathematics and biology using data from 1,148 students attending academically oriented secondary schools in…
