Educational effect of online lecture using streaming technology

Abstract

A conventional lecture on laser engineering had been done in a lecture room till 1999. Content using on-demand streaming method was made for an online lecture of laser engineering in 2000. The figures and equations used in the conventional lecture and the voice recorded for the online lecture were converted to Real Media. Then an online lecture was provided to students by using a Helix Universal Server. The trial of the online lecture was done only for the students who wanted to take the online lecture course in 2000. The online lectures have been recognized as credits for graduation by the change of a law since 2001. About 100 students have registered for the online lecture of laser engineering every year since 2001. Here, three years' questionnaire surveys of the online lecture are summarized, and results of examinations on the conventional lecture for two years and on the online lecture for three years are compared. It is recognized for the lecture on laser engineering that the educational effect of the online lecture is comparable to or better than that of the conventional lecture. © 2008 Wiley Periodicals, Inc.
