Adding a Statistical Wrench to the “Toolbox”

This paper demonstrates a formal statistical test that can be used to help researchers make decisions about alternative statistical model specifications. This test is commonly used by researchers who would like to test whether adding new variables to a model improves the model fit. However, we demonstrate that this formal test can also be employed when alternative representations of variables or constructs are considered for inclusion in a regression. An empirical example is provided using information from a widely cited US Department of Education report. Substantively, we find evidence that an alternative representation of an important policy variable would have been a better fit to the data than the index that was used in the analysis conducted in the report.

Comparing the Utility of the 2000 and 2005 Carnegie Classification Systems in Research on Students’ College Experiences and Outcomes

This study compares the explanatory power of the 2000 edition of Carnegie Classification, the 2005 revision of the classification, and selected variables underlying Carnegie’s expanded 2005 classification system using data from the National Survey of Student Engagement’s spring 2004 administration. Results indicate that the 2000 and 2005 classifications generally offer comparable explanatory power for measures of self-reported gains and student engagement, but the new variables from the 2005 system are more strongly related to cognitive outcomes and engagement than were the two categorical groupings. The variables most consistently related to outcomes and engagement are graduate-undergraduate coexistence, residential character of the campus, and arts and sciences share of undergraduate majors. Implications of the findings for research and assessment are discussed.

The influence of personal networks and social support on study attainment of students in university education

In this paper, the influence of personal networks and social support on study attainment of students in university education is examined. Furthermore, the paper aimed at clarifying the possible mediating role of achievement motivation, time spent on studying and working, procrastination and self-esteem. The study is a follow-up of the ’89 cohort study, but is restricted to those students who have transferred to university education after finishing secondary education. The students have been approached with a questionnaire in 2004. Multinomial logistic regression shows that social support has no effect on study attainment, but that personal networks do have an effect on attainment. The relationship between social support and personal networks on the one hand and study progress on the other hand is not mediated by the before mentioned variables.

ASERA: brief histor(y/ies)

This collection of historical accounts provides diverse perspectives on the structure and culture of the community of researchers who participate in activities of the Australasian Science Education Research Association (ASERA). It describes the formation of the Association, and identifies major changes and challenges for the ever growing and internationalisation of its membership.

The much exaggerated death of positivism

Approaches to research in the social sciences often embrace schema that are consistent with positivism, even though it is widely held that positivism is discredited and essentially dead. Accordingly, many of the methods used in present day scholarship are supported by the tenets of positivism, and are sources of hegemony. We exhort researchers to employ reflexive methods to identify the epistemologies, ontologies and axiologies that are salient in their scholarship and, when necessary, transform practices such that forms of oppression associated with crypto-positivism are identified and extinguished.

Understanding conceptual change: connecting and questioning

We engage in a metalogue based on eight papers in this issue of Cultural Studies of Science Education that review the state of conceptual change research and its possible affect on the teaching and learning of science. Our discussion addresses three aspects of conceptual change research: theoretical, methodological, and practical, as we discuss conceptual change research in light of our experiences as science educators. Finally, we examine the implications of conceptual change research for the teachers and students with whom we work.

Contradictions of time in collaborative school research

The sustainability of research-based innovations in schools is constrained not only by systemic institutional barriers and inherent contradictions between schooling and research, but also by the related issue of time. This case study suggests that relative timescales, e.g., the collective activity of schooling over decades versus the individual actions of researchers over semesters or years, hinder the coordination and synchronization of schooling and research processes. Using cultural–historical activity theory and heterochrony, this analysis of data from a 4-year collaborative school-university research and development project suggests that, in spite of active support from school personnel, temporal conflicts undermined research activity and the sustainability of the innovation. At the same time, when researchers aligned their actions with the actions and timescales of school personnel, core elements of the innovation were appropriated into school practice.

Listening and reflecting: an introduction to the special issue

The topic of listening has been broadly neglected in educational studies. This special issue presents studies on the connections between listening and reflecting in educational contexts.

Growth and diversity in doctoral education: assessing the Australian experience

The major growth of doctoral education in recent decades has attracted attention from policy makers and researchers. In this article we explore the growth of doctoral education in Australia, its impact on diversity in respect of the doctoral population, shifts in disciplinary strengths, institutional concentration and award programs. We conclude that there has been both change and continuity in the provision of doctoral education with extensive variation at the level of practice in what is a reasonably stable system featuring continuing hierarchical institutional diversification. The limitations of available data and issues for further research, policy and practice are discussed.

Assessing Longitudinal Change: Adjustment for Regression to the Mean Effects

Pascarella (J Coll Stud Dev 47:508–520, 2006) has called for an increase in use of longitudinal data with pretest-posttest design when studying effects on college students. However, such designs that use multiple measures to document change are vulnerable to an important threat to internal validity, regression to the mean. Herein, we discuss a brief history of regression to the mean and illustrate a straightforward procedure to make adjustments to initial pretest scores for regression to the mean effects utilizing a method developed by Roberts (in: G. Echternacht (Guest ed.) New directions for testing and measurement, 1980). Analyses are shown with both unadjusted and adjusted pretest scores, illustrating dramatic differences in conclusions about whether students change across time.

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

Exam Scams and Classroom Flimflams: Urban Legends as an Alternative Lens for Viewing the College Classroom Experience

Campus-based urban legends have the potential to convey and construct student culture in higher education. Basic qualitative and humanistic research methods were used to collect, analyze, and interpret legends related to the academic experience of collegiate life.

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.

Critical physics agency: further unraveling the intersections of subject matter knowledge, learning, and taking action

In this rejoinder to Bryan Brown and John Reveles, we highlight the facts that (a) sociocultural theories of learning do not go far enough because they fail to address a number of issues and (b) we require concepts such as power and positionality to understand science learning.

Homicides in Higher Education: Some Reflections on the Moral Mission of the University

This essay on the ethical mission of the university explores extremes of anti-social behavior, visiting numerous crime scenes before concluding that contemporary higher education has lost the capacity—and even the language—for taking character development seriously. In his attempt to determine whether coincidently traditional-liberationist-diversiphilic-apathetic colleges can morally improve their charges, Peter Wood collects a wrenching compendium of violent academic mayhem.

Where practice and theory intersect in the chemistry classroom: using cogenerative dialogue to identify the critical point in science education

This paper argues for an inclusive model of science education practice that attempts to facilitate a relationship between “science and all” by paying particular attention to the development of the relationship between the teacher, students and science. This model hinges on the implementation of cogenerative dialogues between students and teachers. Cogenerative dialogues are a form of structured discourse in which teachers and students engage in a collaborative effort to help identify and implement positive changes in classroom teaching and learning practices. A primary goal of this paper is to introduce a methodological and theoretical framework for conducting cogenerative dialogue that is accessible to classroom teachers and their students. I propose that researchers must learn to disseminate their findings to teachers in ways that are practical, in that they provide teachers with information needed to make concrete connections between the research and their teaching, while continuing to make available the theories that support their findings. Using an integration research framework in conjunction with a temporality of learning model, I introduce a method of disseminating research findings that provides both classroom teachers and researchers with access to different forms of knowledge about cogenerative dialogues in the same paper. In doing so, this article examines the relationships between teacher knowledge and researcher knowledge by exploring the practical application of cogenerative dialogues for classrooms teachers and the theoretical implications of using cogenerative dialogues for researchers.

Graduation Rates and Accountability: Regressions Versus Production Frontiers

This paper suggests an alternative to the standard practice of measuring the graduation rate performance using regression analysis. The alternative is production frontier analysis. Production frontier analysis is appealing because it compares an institution’s graduation rate to the best performance instead of the average performance. The paper explains the differences between these two types of analysis and provides examples of their application using data for 187 national universities.
