Physics and Distance Education
نویسنده
چکیده
Distance education (DE) – the method of teaching and learning in which there is a quasi-permanent separation between students and their teachers – is playing an increasingly important role in the higher education provision of many countries. This article considers in turn the motivations for teaching at a distance, the nature of distance education, the particular challenges of teaching physics at a distance together with some specific examples of how those challenges have been met, and some of the less obvious benefits and opportunities that arise as a consequence of providing distance education in physics. Most systems of distance education rely more or less directly on the available means of communication, so considerations of information and communications technology (ICT) will play an important role in much that follows. The article draws on examples from a number of institutions, but there is a particular emphasis on projects with which I have a personal familiarity, particularly those at my own institution, the Open University of the UK.

Physics concepts of solar ultraviolet radiation by distance education
A series of activities that are suitable for distance education students to illustrate physics concepts related to solar radiation are described. The students can undertake the activities at any location without having to attend the home institution. Detectors interfaced to computers that make the data available on Web pages are employed. The data are updated every 5 min and can be considered t...

Background: An effective polymer gel dosimeter can be fabricated by varying the composition of its chemical components. Materials and Methods: The MAGAT gel dosimeter formulations that used different compositions of Methacrylic acid (MAA) and gelatin were extensively investigated in the present study according to the R2–dose response and R2–dose sensitivity. The irradiation of M...
متن کاملDialogue in a distance education physics course
This study investigated the kinds of dialogues utilized by Open University students while studying an intermediate level physics course. Research objectives were twofold: to document what dialogue types, mediated through which resources, were (1) generally utilized by students as they learned; and (2) were specifically utilized by students to overcome conceptual difficulties. It was found that ...
