DISTANCE LEARNING IN LABORATORY SESSIONS

摘要

The incoming technologies allowing for arnmassive use of remote driven instruments could improve thernquality of the experiments in laboratory sessions, especiallyrnfor what concerns the very specific high level classes.rnMoreover, taking into account the large number of students,rnthe availability of the lab can be greatly extended. In orderrnto give flexibility and high performances to the educationalrntool a user friendly virtual instrument has been realisedrnallowing distance learning. Some basic experiments can bernperformed by the user, namely the analysis of both the RCrnand the RLC circuits, frequency measurements and alsornmeasurements on audio-frequency amplifiers. Indeed, thernuser can make the choice of the experiment which he isrninterested in and can choose the particular procedure amongrnthe implemented ones. By using the adopted procedure thernuser can carry out a proper training without loosing therncontact with real instruments. In order to emphasize thernfeatures of the implemented system some examples arernpresented. A “presence effect” will be added in the nextrnfuture, by using a web camera in the lab.
