Instrumentation and Validation of the Instrument

The study entailed two basic instruments: (a) Task Performance

Evaluation on three topics, namely: Collision Regulation with 14 items,

Williamson Turn with 12 items, and Position Fixing with 10 items; and (b)

Feedback Survey on effectiveness (i.e. 10 items) of the Vehicle Simulator, as

well as ranking of the features (i.e. 8 items) of the said simulation tool.

A detailed profile of the student was required of all respondent-

participants. The same applies to the instructor-respondents. For a more

detailed appreciation of the instrument, please refer to Appendices A, B, C, D, E,

F, G, and H.

Each item in the task performance evaluation was assessed using a 4-

point Likert scale (i.e. ranging from 1 to 4) indicating the extent of the

respondent’s agreement or disagreement. The scale points mean: 1- Poor (P); 2

- Fair (F); 3 – Good (G); and 4 – Very Good (VG). Likewise, corresponding level

has its verbal interpretation as shown in the legend:
