www.utm.my innovative ● entrepreneurial ● global 3 INTRODUCTION Computer simulations programs are based on model to mimic a system as close as reality and often used to bridge the gap between theory and experiment. Using these programs learner can design experiments by changing the values of input variables as precisely as possible to observe the subsequent changes in the output values to establish a relation between them [1]. This kind of learning process is often referred as inductive learning [2] which strongly resemblances to scientific researching, discovery and learning. Lately, inductive learning using computer simulations generated renewed interests [3]

www.utm.my innovative ● entrepreneurial ● global 6 SIGNIFICANCE OF THE RESEARCH The significance of this study cannot be over-emphasized. Below are the significance of this research work: (a)The engineering education experts, teachers and specialists can use the developed model to design educational curricula and methods for solving engineering problems metacognitively. (b)The proposed mode can also help teachers in planning, monitoring and evaluating the metacognitive status of their students. (c)The country can save the cost of employing expatriate by grooming their home-based metacognitive personnel. (d)It will also help a country promote sustainable development since maintenance culture spans through metacognitive thinking and problem solving approach
