Responds from the interviewee collectively agreed that interest and positive attitudes are the most
dominant personal factor that stimulates instructor knowledge. These findings conform and support the
researchers conducted by Boulton-Lewis, et al. (1996) and Tengku Faekah, Hasniza, & Abdul Malek (2008)
that state interest and positive attitude are essential to ensure the teaching and learning processes were carried
out effectively. Interest influence the knowledge acquired since according to Mount, Barrick, Scullen, and
Rounds (2005), interest is a personality that influence the character’s behaviour in making choice and decision.
The results showed that an interest in teaching can be formed by fostering sincerity in duty as well as be
rewarded. This action is consistent with the recommendation made by Harvey-Beavis (2003) to implement
performance-based reward system to motivate the instructors and improve their performance. However,
Harvey-Beavis mentioned that the reward should not be given in the form of monetary or material, but more
effective if psychological rewards such as having fun in work and self-satisfaction were given.
