To improve the teaching and learning materials for a curriculum it is important to incorporate the findings from educational research. In light of this, we present creative exercises and experiments to elicit, confront and resolve misconceptions in geometrical optics. Since ray diagrams can be both the cause and the solution for many…

The design and fabrication of functional scientific instrumentation allows students to forge a link between commonly reported numbers and physical material properties. Here, a two-point and four-point probe station for measuring electrical properties of solid materials is fabricated via 3D printing utilizing an inexpensive benchtop…

Our field has long valued the goal of teaching students not just the facts of physics, but also the thinking and reasoning skills of professional physicists. The complexity inherent in scientific reasoning demands that we think carefully about how we conceptualize for ourselves, enact in our classes, and encourage in our students the relationship…

This paper describes the results achieved by high school seniors on an item which involves translation of the equation P = kT into a corresponding pictorial external representation. The majority of students (the classes of 2011, 2012 and 2013) did not give the correct answer to the multiple choice part of the translation item. They chose pictorial…

Many students enter high school with some science knowledge and experience doing investigations but often know little about the nature of science (NOS) or how the knowledge is developed (i.e., science practices). As science teachers, we need to get students excited about science as quickly as possible with activities that introduce the practices…

This article presents the author's comments on Hisham B. Ghassib's "Where Does Creativity Fit into a Productivist Industrial Model of Knowledge Production?" Ghassib's article focuses on the transformation of science from pre-modern times to the present. Ghassib (2010) notes that, unlike in an earlier era when the economy depended on static…

Monk and Osborne ("Sci Educ" 81:405-424, 1997) provide a rigorous justification for why history and philosophy of science should be incorporated as an integral component of instruction and a model for how history of science should be used to promote learning of and about science. In the following essay we critique how history of science is used on…

The purpose of this study was to examine the relationship between student understanding of the nature of science and their problem-solving strategies. Six hundred and twenty Year 8 students in Taiwan twice completed two conceptual problem-solving tests and a questionnaire on the nature of science. Four of these students were selected for follow-up…

Discussed is the tendency in science to challenge obvious explanation for observed phenomenon. Ten examples are given where the initial obvious explanation was subsequently shown to be totally incorrect. Four examples that relate to biomedicine are presented in detail. (SL)

Past research in a high school genetics classroom has shown that groups of students solving computer-generated genetics problems differed in their application of assessment criteria to the tentative models they generated, and that consistent application of certain model-assessment criteria correlated with success in proposing adequate explanatory…

Documents Swazi students' written explanations of everyday actions in terms of an awareness of the social and economic implications of science, their skills in designing experiments to solve everyday dilemmas, and their abilities to draw on relevant science concepts to solve everyday problems. Finds that considerably less than half of the students…

A set of computer implemented models are presented which can assist in developing problem solving strategies. The three levels of expertise which are covered are beginners (those who have completed at least one university physics course), intermediates (university level physics majors in their third year of study), and professionals (university…

Describes a study of college students who designed and conducted experiments involving control of variables after being assigned to one of four versions of a computer-based biology simulation learning environment. Finds that reason-justification prompts directed students' attention to understanding the employment of experimental design principles…

Describes the Assessment of Performance Unit (APU) Science project. Discusses the findings including perceptions of problems, procedural understanding, control of variables, and measurement strategies. Suggests a change from traditional learning strategies to more student-centered ones. (YP)

This paper reports on the evaluation of an 11-week curriculum created to foster seventh grade students' understanding of scientific modeling. In the curriculum, students engaged in model-oriented activities such as creating non-Newtonian computer microworlds to embody their conceptual models, evaluating their models with criteria, and reflecting…
