AVOW-Tutor

Below is a screen snap shot of AVOW-Tutor.
- AVOW-Tutor combines two representations for learning about
electrical circuits
- Conventional circuit diagrams
- LEDs called AVOW diagrams. AVOW stands for Amps, Volts,
Ohms and Watts.
- The user can constructs conventional circuit diagrams on the
left.
- The AVOW diagrams are constructed in the large area on the
right.
- Each AVOW box represents one resistor. Height=current (I),
width=voltage (V), gradient of the diagonal=resistance (R),
area =power dissipated (P).
- AVOW boxes encode Ohms law (V=I.R) and the power law
(P=V.I).
- Rules for drawing AVOW diagrams: series resistors are
placed vertically on top of each other; parallel resistors are
placed side by side; a well-formed AVOW diagram is a rectangle
completely filled with AVOW boxes.
- Bottom left area is the tutorial authoring control panel.
- Bottom right area is a message window.
- AVOW-tutor can automatically check the consistency of the
circuit and diagram.
