Adrian Adams; Lauren Barth-Cohen – CBE - Life Sciences Education, 2024
In undergraduate research settings, students are likely to encounter anomalous data, that is, data that do not meet their expectations. Most of the research that directly or indirectly captures the role of anomalous data in research settings uses post-hoc reflective interviews or surveys. These data collection approaches focus on recall of past…

Levy, Smadar; Noga, Adi; Kapach, Zehorit; Yerushalmi, Edit – Physics Education, 2022
The instructional lab setting has been found to be dominated by prescribed tasks and pre-prepared lab kits. This was explained by teachers' need to guide students to simultaneously progress through a lab curriculum, which prompts them to standardize the lab experience. Nevertheless, prominent professional associations have persistently called to…

Harsha, N. R. Sree; Sreedevi, A.; Prakash, Anupama – Physics Education, 2015
Despite a number of theories in circuit analysis, little is known about the behaviour of ideal equal voltage sources in parallel, connected across a resistive load. We neither have any theory that can predict the voltage source that provides the load current, nor is there any method to test it experimentally. In a series of experiments performed…

Ocaya, R. O.; Luhanga, P. V. C. – European Journal of Physics, 2011
It is shown that the well-known linear variation of p-n diode terminal voltage with temperature at different fixed forward currents allows easy and accurate determination of the semiconductor ideality factor and bandgap from only two data points. This is possible if the temperature difference required to maintain the same diode voltage drop can be…

Thoman, Dustin B.; Sansone, Carol; Fraughton, Tamra; Pasupathi, Monisha – Contemporary Educational Psychology, 2012
Social influences (e.g., by teachers, parents and peers) on students' experience of interest are typically described in terms of affecting students' initial choice of and/or completion of specific educational activities. When considered within the framework of the Self-Regulation of Motivation (SRM) model, however, other people may influence the…

Ozdemir, Omer Faruk – International Journal of Science Education, 2009
Two independent lines of research--mental simulations and thought experiments--provide strong arguments about the importance of perceptual modalities for the instructional practices in science education. By situating the use of mental simulations in the framework of thought experiments, this study investigated the nature and the role of mental…

Hatzikraniotis, E.; Kallery, M.; Molohidis, A.; Psillos, D. – Physics Education, 2010
This article examines secondary students' design of experiments after engagement in an innovative and inquiry-oriented module on heat transfer. The module consists of an integration of hands-on experiments, simulated experiments and microscopic model simulations, includes a structured series of guided investigative tasks and was implemented for a…

LoPresto, Michael C.; Jacobs, Diane A. – Physics Education, 2007
In this exercise the US Standard Atmosphere is used as "data" that a student is asked to model by deriving equations to reproduce it with the help of spreadsheet and graphing software. The exercise can be used as a laboratory or an independent study for a student of introductory physics to provide an introduction to scientific research…

Stacewicz, T.; Wasylczyk, P.; Kowalczyk, P.; Semczuk, M. – European Journal of Physics, 2007
A simple experiment is described that permits advanced undergraduates to learn the principles and applications of the cavity ring down spectroscopy technique. The apparatus is used for measurements of low concentrations of NO[subscript 2] produced in air by an electric discharge. We present the setup, experimental procedure, data analysis and some…

Fazio, Claudio; Guastella, Ivan; Sperandeo-Mineo, Rosa Maria; Tarantino, Giovanni – International Journal of Science Education, 2008
The present paper reports the design process and the experimentation of a teaching-learning sequence about the concept of mechanical wave propagation and the role played by media where waves are propagating. The sequence focuses on the central issue of the relationships between observable phenomena, like macroscopic behaviours of waves, and their…

Rodriguez, Maria A.; Niaz, Mansoor – Instructional Science: An International Journal of Learning and Cognition, 2004
The objectives of this study are: (1) evaluation of the methodology used in recent search for particles with fractional electrical charge (quarks) and its implications for understanding the scientific research methodology of Millikan; (2) evaluation of 43 general physics textbooks and 11 laboratory manuals, with respect to the oil drop experiment,…

Weinberg, Robert – Physics Teacher, 1974
Discusses a student project which is intended to teach undergraduates concepts and techniques of nuclear physics, experimental methods used in particle detection, and provide experience in a functioning research environment. Included are detailed procedures for carrying out the project. (CC)

Bryan, Joel Arthur – Journal of College Science Teaching, 2006
Preservice elementary teachers in a conceptual physics course were given multiple resources to use during several inquiry activities in order to investigate how materials were chosen, used, and valued. These students performed significantly better on assessment items related to the inquiry physics activities than on items related to traditional…

Richards, D. A. – Physics Education, 1981
Describes an experiment on a coupled system in which accurate timing is carried out using a Light Activated Switch (LAS) technique. LAS can be used for a wide range of periodic phenomena, provided the amplitude is sufficiently large to interrupt a light beam. (Author/SK)

Tinnesand, Michael; Chan, Alan – Science Teacher, 1987
Argues that cookbook chemistry laboratory experiments do little to teach scientific inquiry. Suggests providing students with laboratory experiences that follow the introduction of a concept and challenge students to investigate that concept through an experiment involving very few initial instructions. Lists some such challenges used in chemistry…
