Replication and Pedagogy in the History of Psychology VI: Egon Brunswik on Perception and Explicit Reasoning

Egon Brunswik (1903–1955) first made an interesting distinction between perception and explicit reasoning, arguing that perception included quick estimates of an object’s size, nearly always resulting in good approximations in uncertain environments, whereas explicit reasoning, while better at achieving exact estimates, could often fail by wide margins. An experiment conducted by Brunswik to investigate these ideas was never published and the only available information is a figure of the results presented in a posthumous book in 1956. We replicated and extended his study to gain insight into the procedures Brunswik used in obtaining his results. Explicit reasoning resulted in fewer errors, yet more extreme ones than perception. Brunswik’s graphical analysis of the results led to different conclusions, however, than did a modern statistically-based analysis.

The Long Decay Model of One-Dimensional Projectile Motion

This article introduces a research study on student model formation and development in introductory mechanics. As a point of entry, I present a detailed analysis of the Long Decay Model of one-dimensional projectile motion. This model has been articulated by Galileo (in De Motu) and by contemporary students. Implications for instruction are discussed.

Replication and Pedagogy in the History of Psychology IV: Patrick and Gilbert (1896) on Sleep Deprivation

We report an attempted replication of G. T. W. Patrick and J. A. Gilbert’s pioneering sleep deprivation experiment ‘Studies from the psychological laboratory of the University of Iowa. On the effects of loss of sleep’, conducted in 1895/96. Patrick and Gilbert’s study was the first sleep deprivation experiment of its kind, performed by some of the first formally trained psychologists. We attempted to recreate the original experience in two subjects, using similar apparatus and methodology, and drawing direct comparisons to the original study whenever possible. We argue for a strong influence of an ‘Americanized’ Wundtian psychology on Patrick and Gilbert, a claim supported biographically by their education and by their experimental methods. The replication thus opens interesting new perspectives, which are unlikely to be generated by any other historical approach.

A New Way of Thinking about Social Location in Science

The Durkheimian concept of the density of social relationships may prove more fruitful than the historical materialist notion of a social hierarchy for thinking about the social location of epistemic agents in science. To define a scientist’s social location in terms of the density of her professional relationships with other scientists permits us to give a more precise characterization of marginalization and thus to formulate more testable hypotheses about marginalized groups in science. The notion of social density helps to explain not only how some individual scientists are more likely than others to get a hearing for their ideas, but also how scientific inquiry flourishes more in some societies than in others.

Peer Coaching: Professional Development for Experienced Faculty

The professoriate, as a whole, is growing older and more experienced; yet institutions often overlook the professional development needs of mid-career and senior faculty. This article, based on a review of the literature and the development of a peer coaching project, examines peer coaching as a professional development opportunity for experienced faculty that meets many of their immediate needs and offers a variety of longer-term benefits to their institution. Six recommendations for creating a peer coaching program emerge from the literature and the authors’ experience.

Replication and Pedagogy in the History of Psychology II: Fowler & Wells’s Phrenology

Phrenologists believed that specific brain regions corresponded to certain character traits. In addition, the size of each brain region was believed to determine the strength of the respective trait. Phrenology originated in Austria with Franz Josef Gall and was popularized and commercialized in America at the end of the 19th century by Orson Squire Fowler. In this project, we conducted a replication of Fowler’s phrenology in order to better understand the specificity of the manualized methodology, the extent to which the methodology allowed for positive versus negative analyses, and the implications for the scientific rejection and public acceptance of phrenology. The results of our replication revealed that the subjective judgments and biases of the examiner strongly influence the results of phrenological analyses. This project originated as a class assignment in the Spring of 2003 (Tweney, this issue). See Tweney (2004) for general information on historical replication.

A Network Approach to Preparing Underrepresented Students: The LEAD Model

Results are reported from an empirical study of an interorganizational collaboration to prepare underrepresented students for elite postsecondary education and beyond. The LEAD (Leadership Education and Development) Program in Business is an initiative involving twelve U.S. universities, nearly forty multinational corporations, a federal government agency, and a nonprofit organization working together to introduce students to business education and careers in business. This article analyzes the conditions that give rise to the collaboration, its essential structural characteristics, and the consequences that flow from it.

How might Native science inform “informal science learning”?

This article examines the literature on Native science in order to address the presumed binaries between formal and informal science learning and between Western and Native science. We situate this discussion within a larger discussion of culturally responsive schooling for Indigenous youth and the importance of Indigenous epistemologies and contextualized knowledges within Indigenous communities.

Better Red than Dead—Putting an End to the Social Irrelevance of Postwar Philosophy of Science

This paper asks what is necessary in a theory of science adequate to the task of empowering philosophers of science to participate in public debate about science in a social context. It is argued that an adequate theory of science must be capable of theorizing the role of values and motives in science and that it must take seriously the irreducibly social nature of scientific knowledge.

Transmutation of Matter in Byzantium: The Case of Michael Psellos, the Alchemist

There is thus nothing paradoxical about the inclusion of alchemy in the ensemble of the physical sciences nor in the preoccupation with it on the part of learned men engaged in scientific study. In the context of the Medieval model, where discourse on the physical world was ambiguous, often unclear, and lacking the support of experimental verification, the transmutation of matter, which was the subject of alchemy, even if not attended by a host of occult features, was a process that was thought to have a probable basis in reality. What is interesting in this connection is the utilization of the scientific categories of the day for discussion of transmutation of matter and the attempt to avoid, in most instances in the texts that survive, of methods reminiscent of magic.

The Concept of Nondeterminism: Its Development and Implications for Teaching

Nondeterminism is a fundamental concept in computer science that appears in various contexts such as automata theory, algorithms and concurrent computation. We present a taxonomy of the different ways that nondeterminism can be defined and used; the categories of the taxonomy are domain, nature, implementation, consistency, execution and semantics. An historical survey shows how the concept was developed from its inception by Rabin & Scott, Floyd and Dijkstra, as well as the interplay between nondeterminism and concurrency. Computer science textbooks and pedagogical software are surveyed to determine how they present the concept; the results show that the treatment of nondeterminism is generally fragmentary and unsystematic. We conclude that the teaching of nondeterminism must be integrated through the computer science curriculum so that students learn to see nondeterminism both in terms of abstract mathematical entities and in terms of machines whose execution is unpredictable.

The Necessity of Making Visible Concepts with Multiple Meanings in Science Education: The Use of the Gene Concept in a Biology Textbook

The purpose of this study is to analyze variations in how the gene concept is used and conceived in different sub-disciplines in biology. An examination of the development of subject matter and the use of the gene concept in a common college biology textbook shows that the gene concept is far from presented in a consistent way. The study describes and categorizes five different gene concepts used in the textbook; the gene as a trait, an information-structure, an actor, a regulator and a marker. These conceptual differences are not dealt with in an explicit manner. This constitutes one of the sources for confusion when learning about genes and genetics.

A Role for Experiment in Using the Law of Inertia to Explain the Nature of Science: A Comment on Lopes Celho

The whole mode of Galileo’s discovery of the Law of Inertia is an excellent exemplar of the Nature of Science. The law can, moreover be shown to be a direct consequence of the hypothesis that space is homogeneous and isotropic and time is homogeneous

The Dark Side of “Postmodern Moonshine”

In our summer 2006 issue, we ran a comprehensive overview of how postmodernism has degraded composition on our campuses. Steve Kogan enlarges that indictment and charges that the movement has deliberately corrupted every area of English instruction—from the acquisition of skills and knowledge to the more fundamental mission of developing in students the habits of disciplined learning.

Roger Osborne (1940–1985), University of Waikato, New Zealand

This short paper outlines the emergence and achievements of the Science Education Research Unit at the University of Waikato over the period 1979–1985 under the leadership of the late Dr. Roger Osborne. Following his attendance at the ASERA meeting in Wagga Wagga in 1977, Roger Osborne rapidly built up a very productive team, which he led until his death in 1985. His legacy is tentatively evaluated. In conclusion, the cultural context in which this work took place is sketched.

The Distinction Between Epistemic and Non-Epistemic Values in the Natural Sciences

In this paper I examine the particular question of the meaning of the distinction between epistemic and non-epistemic values in the natural sciences and, if this would make sense, the possibility to transcend this distinction. I claim that the distinction between epistemic and non-epistemic values maintains its necessity as long as a certain sort of unity between the theoretical and the practical sides of the scientific endeavour has not been achieved. The distinction in question would cease to have meaning only from the perspective of such a unity, since in this manner the normative dimension of science would become an internal term for its historical construction.

Priority Education Zones in Mauritius

This article discusses the Priority Education Zones project (ZEP) in Mauritius. The original and innovative dimensions of the project are described, together with the difficulties encountered during the setting-up of the ZEP schools. The article covers five main issues: the status of the ZEP project; the minimal conditions for success; the implications concerning the teachers; the obstacles faced; and the strategy devised to implement the ZEP project, while overcoming the obstacles.

Clergy’s Views of the Relationship between Science and Religious Faith and the Implications for Science Education

Since many teachers and students recognize other kinds of knowledge (faith) based on other ways of knowing, consideration of these realities is appropriate for the science education community. Understanding the multitude of ways that clergy view relationships between science and faith (i.e. alternative ways of knowing) would assist in understanding various ways that people address complex issues arising from ideas about science and faith. We administered a questionnaire composed of multiple-choice and short answer items to 63 United Methodist ministers. Findings included (1) that formal, organized faith contexts (e.g. church services) serve as informal science education opportunities, (2) participants demonstrated considerable diversity regarding the types of relationships developed between science and faith, and (3) participants recognized a need exists for better understandings of science and its relationship to faith for them, their colleagues, and their congregations.
