We designed and implemented curriculum intended to be used by students in an algebra-based introductory physics laboratory course. Our curricular goal was to foster, through observations in the lab, a coherent framework in students' understanding of general principles presented in the introductory mechanics course, while addressing known student…

Technological fields, like engineering, are in desperate need of more qualified workers, yet not enough students are pursuing studies in science, technology, engineering, or mathematics (STEM) that would prepare them for technical careers. Unfortunately, many students have no interest in STEM careers, particularly engineering, because they are not…

Nine academics participated in semi-structured interviews to explore possible linkages between their teacher identities and the pedagogies they employ. A content analysis of the interviews was performed to gain insight into the factors playing a role in how academics define themselves as teachers, the larger educational goals they espouse and the…

The study was conducted to find out the attitude of students towards the use of cooperative, competitive and individualistic learning strategies in Nigerian senior secondary school physics. The design selected for this study was quasi-experimental. A total of 140 students took part in the study and they were selected by a random sampling…

The International Young Physicists' Tournament (IYPT) is a worldwide, annual competition for secondary school students. This is our solution to problem number 10, "The Kaye effect", as presented in the final round of the 21st IYPT in Trogir, Croatia. The Kaye effect occurs when a thin stream of shampoo or a different adequate non-Newtonian liquid…

A problem-based approach to the teaching of mechanical wave propagation, focused on observation and measurement of wave properties in solids and on modelling of these properties, is presented. In particular, some experimental results, originally aimed at measuring the propagation speed of sound waves in metallic rods, are used in order to deepen…

Employment of a data-acquisition system for data collection and calculations makes experiments with antennas more convenient and less time consuming. The determined directional patterns of the dipole antennas of different lengths are in reasonable agreement with theory. The enhancement of the signal by using a reflector is demonstrated, and a…

As physics teachers at the collegiate level, we are faced with the difficulty of lack of interest in science among non-science majors. An example of this occurred in a conceptual physics course at West Virginia University, where we taught mostly students attending the education college. A poll taken of the class found 62% of the students wrote…

This article addresses postural awareness and efficiency as a fundamental but often overlooked aspect of movement training that falls naturally into the domain of HPERD pedagogical practice. Beginning with a brief overview and discussion on the anatomical "cost" of poor organization, the body of the article describes activities that can be…

This paper introduces five commonly used approaches to analyzing multiple-choice test data. They are classical test theory, factor analysis, cluster analysis, item response theory, and model analysis. Brief descriptions of the goals and algorithms of these approaches are provided, together with examples illustrating their applications in physics…

Common forms of testing of student understanding of science content can be misleading about their understanding of the nature of scientific thinking. Observational astronomy integrated with related ideas of force and motion is a rich context to explore the correlation between student content knowledge and student understanding of the scientific…

Twelfth-grade physics classes with 344 students participated in a quasi-experimental study comparing two small-group learning settings. In the jigsaw classroom, in contrast to the cyclical rotation method, teaching expectancy as well as resource interdependence is established. The study is based on the self-determination theory of motivation,…

Interactivity, group learning and student engagement are accepted as key features of social constructivist learning theories. The challenge is to understand the interplay between such features in different learning environments. This study focused on the qualitative differences between two interventions--small-groups and whole-class discussions.…

Many large scientific projects and scientific centres incorporate some kind of outreach programme. Almost all of these outreach programmes include public scientific lectures delivered by practising scientists. In this article, we examine such lectures from the perspectives of: (i) lecturers (7) who are practising scientists acknowledged to be good…

Project work is the primary method which enables practicing the activities that contemporary learning theories suggest. The aim of this study is to determine the issues encountered during project work in accordance with students' and teachers' views in secondary schools physics courses in the city of Trabzon, Turkey where project work has been…
