Our technological, information-rich society thrives because of scientific thinking. However, a comprehensive theory of the development of scientific thinking remains elusive. Building on previous theoretical and empirical work in conceptual change, the role of credibility and plausibility in evaluating scientific evidence and claims, science…

Advancing equity and justice in undergraduate biology education requires research to address the experiences of disabled students. Scholars working in disability studies have developed models of disability that inform Discipline-Based Education Research (DBER). To date, DBER literature has been predominantly informed by the medical and social…

The importance of the philosophy of science in science teacher education has long been argued for by science educators. In particular, understanding how scientific knowledge is generated, negotiated, and developed is a key area of the philosophy of science that is relevant to science teaching. However, research on the nature of scientific…

In this article, I explicate where my theoretical work on creativity has been and where it is going. I describe earlier three-facet and investment theories, as well as a propulsion model. I then describe my new triangular theory of creativity.

This account of practice focuses on an augmented Customer Development methodology which the author adopted for a module in a Master's program in Entrepreneurship at a Swedish business school. The article details the techniques underlying this augmented methodology, and the journey toward its implementation. By conceptualizing…

This paper presents a history of research and theories on sliding friction between solids. This history is divided into four phases: from Leonardo da Vinci to Coulomb and the establishment of classical laws of friction; the theories of lubrication and the Tomlinson's theory of friction (1850-1930); the theories of wear, the Bowden and Tabor's…

Purpose: The author presents a view of research in speech motor control over the past 5 decades, as observed from within Ken Stevens's Speech Communication Group (SCG) in the Research Laboratory of Electronics at MIT. Method: The author presents a limited overview of some important developments and discoveries. The perspective is based…

Biomedical research has produced vast amounts of new information in the last decade but has been slow to find its use in clinical applications. Data from disparate sources such as genetic studies and summary data from published literature have been amassed, but there is a significant gap, primarily due to a lack of normative methods, in combining…

Design-based research, and particularly its theoretical status, is a subject of debate in the science education community. In the first part of this paper, a theoretical framework drawn up to develop design-based research will be presented. This framework is mainly based on epistemological analysis of physics modelling, learning and teaching…

Reports recent findings related to the particle Higgs boson and examines its possible contribution to the standard mode of elementary processes. Critically explores the strengths and uncertainties of the Higgs boson and proposed Higgs field. (ML)

Recent research studies of both classifications of ocean margins (active or of Pacific type and passive or of Atlantic variety) have yielded a considerable amount of new information leading to some new theories. These theories regarding different kinds of tectonic activity are discussed. (BT)

Reviews the developments in S-matrix theory over the past five years which have made it possible to derive results characteristic of quark models without any need to postulate the existence of physical quarks. In the new approach, the quark patterns emerge as a consequence of combining the general S-matrix principles with the concept of order.…

Historically described are research studies which led to the current explanation of the two kinds of intracellular transport-axoplasmic flow and axoral transport. Models explaining their fundamental mechanism and the kinds of materials they convey are presented. (BT)
