We use data from the 1990/1994 Beginning Post-Secondary Survey to determine whether the factors associated with long-term attrition from higher education differ for students who initially enrolled part-time as compared to for students who initially enrolled full-time. Using a two-stage sequential decision model to analyze the initial enrollment…

Most research in the area of higher education is plagued by the problem of endogeneity or self-selection bias. Unlike ordinary least squares (OLS) regression, propensity score matching addresses the issue of self-selection bias and allows for a decomposition of treatment effects on outcomes. Using panel data from a national survey of bachelor's…

This study extends the extant research demonstrating the educational benefits of diversity and examines how undergraduate students across disciplinary contexts acquire a set of pluralistic skills and dispositions necessary for today's diverse workforce and society. The sample consisted of 4697 students who participated in a longitudinal study in…

This study reports the results of a survey of 2700 employees in business operations at a large public, research university. The analysis tests Herzberg et al.'s ("1959") well-known, duality theory of motivators and hygiene factors and the impact of personal characteristics and job characteristics on perceptions of the work environment and job…

The products of modern biotechnology processes such as genetic engineering, DNA testing and cloning will increasingly impact on society. It is essential that young people have a well-developed scientific understanding of biotechnology and associated processes so that they are able to contribute to public debate and make informed personal…

The importance of argumentation in science education is outlined and the relatively low level of argumentation typically observed in classrooms in the UK is noted, along with possible reasons for this. The research sets out to determine the extent to which primary school pupils engage in argumentation and to characterise their arguments in primary…

Creativity is recognised as a valuable human quality for personal, social, technological and economic reasons and many school curriculum documents assert that creativity can be taught. In science education it is often argued that it is through engagement in practical work that students develop their possibility thinking and problem solving…

This paper reports the experiences of teachers involved in a novel retraining scheme designed to meet a short-term crisis in numbers of teachers of physics. Teachers trained in other subject areas underwent an intensive six-month training in physics and were then placed in schools. During the first year of teaching some support for ongoing…

The theory of conceptual change is criticized because it focuses only on supposed underlying logical structures and rational process processes, and lacks attention to affective aspects as well as motivational constructs in students' learning science. This is a vast underestimation of the complexity and diversity of one's change of conceptions. The…

This paper reports on degrees of awareness and use of specific metacognitive strategies by 16 students in a final-year high school biology class in New Zealand. The aims of the intervention were to broaden students' thinking about bioethical issues associated with cancer and to enhance students' use of metacognition. Cues and prompts were used in…

With the growing emphasis on the development of scientific inquiry skills, there is a strong need for more research on students' ability to collect and interpret evidence. This paper calls attention to the notion of evidentiary competence that refers to the concepts and reasoning skills involved in the collection, organization, and interpretation…

Lack of confidence towards science is a major factor in the avoidance of teaching science at elementary school. This paper reports the results of a survey that asked 28 pre-service elementary teachers what they believed contributed to their confidence towards science and the teaching of science during a second year science unit where an holistic…

"School Innovation in Science" represents a model, developed through working with more than 200 Victorian schools, to improve science teaching and learning. SIS works at the level of the science team and the teacher, providing resources to challenge and support the change process. Its emphasis is on strategic planning supported by a framework for…

As teachers' knowledge determines to a large extent how they respond to educational innovation, it is necessary for innovators to take this knowledge into account when implementing educational changes. This study aimed at identifying patterns in the content and the structure of science teachers' knowledge, at a point in time when they still had…

This article employs the concept of community to interpret teacher professional learning in the context of the school science department. Using the transcripts of staff meetings, lesson observations and the conversations of school administrators, the departmental community is examined in terms of three metaphors: subject, relationships and…
