Abstract


This paper discusses the functional system of a learning media product development; the design and implementation of a virtual lab with analog oscillator comprised of the following: i) Wien Bridge oscillator, ii) Colpitts oscillator, iii) Hartley oscillator and, iv) Astable Multivibrator. The virtual laboratory was built using Adobe Flash CS6 Action Script 3.0. This media can be accessed offline on a computer standalone based on the extension .exe or .swf and constructed with 24 frames per second (fps). This media can be operated by changing the Resistor (R), Inductor (L) and Capacitor (C) components via ‘plug and play’ to the tool-kit, or trainer kit, while the output can be seen in the measuring devices, namely: the frequnecy counter and oscilloscope. The second product is a digital jobsheet as a supplementary element for the practical, which contains prequisites for conducting practical use, introductory, and anatomic information of the virtual lab, as well as the directions for using the e-jobsheet and virtual lab, the practical procedures, and the test items for evaluation.
