The nature of scientific knowledge and student learning: Two longitudinal case studies

This study was designed to investigate the relationship between students' views of the nature of scientific knowledge and their own learning of physics, and the evolution of this relationship over time. Twenty-three students enrolled in a physics course that emphasised laboratory work and discussions about the nature of science. Over a 15-month period, an extensive data base was established including student essays and interviews regarding their views of the nature of science and teaching and learning of physics. As part of an extensive data generation, students read a book on the epistemology of physics, wrote reflective essays, and subsequently discussed the epistemology of physics in class. Two intensive case studies are used to illustrate our understanding of students' views over time. Changes in students' views concerning the nature of scientific knowledge and of the science teaching and learning process, which were not always complementary, are described with the aid of a model. The findings of this research have direct relevance to the planning and implementation of science courses in which the development of understandings of the nature of science is an objective.     

Centralized administration and academic credit base in experiential education

The Off-Campus Term (OCT) Program of the University of South Florida is a model in experiential education of centralized administration and in granting academic credit. In contrast to many programs where the experiential office serves in a coordinating role, but the academic work is under the supervision of classroom faculty, the OCT Program encompasses all of this under one program umbrella. Further, the program is comprehensive in nature providing for any kind of off-campus experience desired by the student. The methods and systems used, both functional and academic, are described along with the strengths and weaknesses of the OCT centralized model.     

Explaining the variance in reading ability in terms of psychological processes: What have we learned?

After years of confusion, the literature on individual differences in reading ability is finally beginning to coalesce around a small set of general conclusions that are endorsed by the vast majority of researchers. The most fundamental is that word decoding ability accounts for a very large proportion of the variance in reading ability at all levels. Variation in word decoding skill is primarily the result of differences in phonological abilities, rather than visual processes. Less-skilled readers are not characterized by a general inability to use context to facilitate word recognition. However, situations where such readers fail to utilize context to facilitate word recognition will arise when their slow and inaccurate decoding of words renders the context useless. Less-skilled readers display performance deficits on a wide variety of short-term memory tasks, probably due to an inability to efficiently employ various memory strategies, and most certainly due to inadequate phonological coding. Less-skilled readers may have comprehension deficits that are partially independent of word decoding skill. These problems probably arise because syntactic abilities and metacognitive strategies are inadequately developed.

'You'd Be Wanting to Know about the Past': Social contexts of children's historical understanding in Northern Ireland and the USA

This research reports the results of two studies of young children's historical thinking, one conducted in Northern Ireland and one in the USA. In both countries, primary/elementary students learn about history in a variety of settings, including not only schools but also family conversations, historic sites and the media. The differing nature of historical representations in the two countries, however, leads students to contrasting conclusions about the purpose of learning about the past: in the USA, students emphasise that history is important so that they will know about the origin of their country and their own place within it, while in Northern Ireland students describe the purpose of history as being to learn about those who are different from themselves. In both countries, such comparative evidence about children's thinking provides educators with the opportunity to consider how they can build on and extend students' understanding of history.
