Abstract
In this paper we present a tool that virtualizes creation and execution of large address space programs, and visualizes working of virtual memory system in response to their virtualized execution to facilitate effective teaching-learning of the abstract concept and technical details of virtual memory system. The tool allows users to write large address space virtual programs using a small set of instructions, virtualize their execution and visualize the working of virtual memory system in response to their virtualized execution. We also evaluated students' response towards the tool to investigate its teaching-learning effectiveness and acceptance by student community. The results suggest that with respect to the Technology Acceptance Model variables, students had positive values indicating a tendency to be favorable towards using the tool in their learning. Students exhibited high intention to use the tool, demonstrated a high positive attitude towards the tool, and showed high perceived usefulness of the tool to acquire complete, concrete and confident knowledge of virtual memory system.
