In the study of Taperla (2009), the Students and Professors were made to validate the Acceptability of the Multi-Circuit Magnetic Motor Control Trainer using the 5 - point Likert Scale. Provide data on the table that follows: TRAINER DESIGN AS TO DIAGRAM STUDENTS (N1=20) OF CONTROL & POWER CIRCUIT 5 4 3 2 1 TWP X VD Symbols used are ANSI standards 12 8 0 0 0 Schematic diagram of control circuit is clear 20 0 0 0 0 and properly illustrated Line diagram of power circuit is clear and properly illustrated 12 5 3 0 0 Tracing of the circuit is simplified by schematic 8 Wiring diagram into schematic can be easily translated AVERAGE WEIGHTED MEAN STANDARD DEVIATION Legend: * is the weighted mean, VD is Verbal Description, 1.00 - 1.79 (UA) Unacceptable, 1.80 - 2.59 (LA) Least Acceptable, 2.60 - 3.39 (A) Acceptable, 3.40 - 4.19 (MA) Moderately Acceptable, 4.20 - 5.00 (HA) Highly Acceptable
