This response builds upon Marie Paz Morales' "Influence of culture and language sensitive physics on science attitude achievement" by exploring how an expanded understanding of the ubiquitous nature of adolescent literacy practices and identities challenge traditional notions of "in school" and "out of school"…

The authors appreciate Professor Slotta's responding to their critique (Slotta, this issue). For their part, they believe that Professor Slotta has misinterpreted aspects of their position. In this commentary, the authors clarify two particular points. First, they explain their use of "static ontologies," which they maintain applies. Second, they…

Black, Wilson, and Yao (this issue) commendably attempt to put descriptive theory at the center of pedagogy, assessment, and curriculum. The thrust of their article is that only through theories of learning will student progression be properly understood. Casting a critical eye over the faddish distinction between "formative" and "summative"…

The Stoics of the Roman Imperial period share the imperative that education should not focus on erudition for its own sake, but contribute to the pursuit of the good life as they define it in philosophical terms. Hence these later Stoics express similar concerns about the technical and theoretical aspects of philosophy as they do about…

In last month's issue of "TPT," Michael Sobel turns our attention to the increasing number and broader population of students taking physics courses and urges us to reconsider how to better cater to their needs. We applaud the author for focusing our attention on this important issue. However, we find his proposal for teaching physics to…

This interview provides glimpses of Joseph J. Lagowski and his life from the time he played with a Gilbert chemistry set, to his tenure at The University of Texas at Austin. His initial interest in chemistry was further nurtured and developed thanks to an excellent high school teacher. In the interview, Lagowski discusses his research in…

Contemporary learning research and development that is embedded in primary and secondary schooling is increasingly acknowledging the significance of a variation approach for enhancing the possibility of learning. However, the variation approach has so far attracted very little attention in higher education, but where it has, the results have been…

Presents Newton's main ideas for the formulation of classical mechanics as given in the Principia. Discusses Ernst Mach's criticisms of Newtonian mechanics as contained in his book, "The Science of Mechanics". Analyzes the influence of Mach's ideas in the teaching of classical mechanics by considering five textbooks. Concludes that…

Argues that inclusion of demonstrations on examinations increases students' ability to observe carefully the physical world around them, translate from observation in terms of models, and make quantitative estimates and physicist-type "back-of-the-envelope" calculations. Presents demonstration ideas covering the following topics:…

Makes a recommendation for more direct teaching of the basic principles of mechanics. Contends that students currently learn mechanics in terms of standard examples. This causes difficulty when the student is confronted with a problem that can be solved from basic principles, but which does not fit a standard category. (GS)

Presents an approach to combine the empirical approach of classical thermodynamics with the structural approach of statistical mechanics. Topics covered include dynamical foundation of the first law; mechanical work, heat, radiation, and the first law; thermal equilibrium; thermal processes; thermodynamic probability; entropy; the second law;…

Individual teachers of college level physics sometimes develop deep insights into how their students learn and what elements of classroom instruction are valuable in facilitating the learning process. Yet, these insights rarely persist beyond the individual instructor. Educational methods seem to cycle from one fad to another, rarely cumulating…

Examines the principles of diffusion and how it may be confused with convection. Suggests that educators may be misleading students and clouding their understanding of the process. Provides two contemporary examples to explain the process of diffusion and how it differs from convection. (Author/CCM)

Describes how one professor makes his physics course relevant to pharmacy majors. The course emphasizes the relation of basic physics concepts (like forces and thermodynamics) to the human body and uses problems drawn from the medical profession. Student course evaluations show a favorable view of content learned and its relevance. (DB)

Argues that physics education reform has been focused on classroom-based innovation rather than on the more political and institutional conditions required for long-lasting change. Stresses that reformers should pay attention to exogenous variables that get in the way of real reform. (Author/CCM)
