We report the simulation models for enhancing the metacognitive skills. Mechanical Engineering students of Babylon Institute in Iraq are chosen for case study. The design of model and Impact Test Simulations (ITS) for Metallurgy subject is addressed. The simulation software developed using Microsoft Studio 2010 includes tutorials to explain all necessary theoretical background and formulas. Step-by-step computerized procedures and numerical examples are rendered in a simple user-friendly, visual and interactive environment to enhance metacognitive skills and students' learning. Before starting the design process, objectives and the salient features of simulation are clearly identified. Subsequently, real laboratory experiments are conducted for collecting data and coding them in computer language. Despite the existence of numerous module embedded graphical simulation, the developed software package is expected to provide valuable tool for both students and instructors. Furthermore, the same package in the form of a bi-product can also be used as a "research tool" together with the application for engineering education
