Solving Problems in a Physical Laboratory for Computer Networks and Data Security: A Conceptual Framework with Students Experiences

摘要

Professional engineering practice requires engineers capable for solving real problems, putting problem solving skills in the focus of contemporary engineering education. Identification, systematization, evaluation and reuse of students' experiences in problem solving are necessary for assessing and improving educational processes. Due to the high importance of computer networks and data security for contemporary business, practical experience in physical laboratories is essential for educating engineers for challenges in engineering workplaces. This article presents a study aimed at exploring students' problem solving experiences in a physical laboratory for computer networks and data security. The study is based on qualitative research methods, resulting in a conceptual framework that describes students problem solving experiences. The framework presents identified types of problems and effects of problems solving for students. The problem types relate to the complexity of scenarios prepared for the laboratory, setting up and configuring laboratory equipment, and configuring and using a variety of software tools. Effects of problem solving relate to learning to use different sources of information, learning through joint work and sharing experiences, learning from more experienced colleagues and learning skills that exceed the learning goals. Benefits, implications and outcomes of the research for students, lecturers and researchers are discussed, together with the limitations and further research directions.
