There are many problems in delivering a constantly changing computer networking syllabus to students. These problems are exacerbated by the increasing number of complex protocols that may have to be learnt in a short period of time. Abstract models, known as State Model Diagrams (SMDs), may help to address some of these problems. The authors wished to test whether SMDs could also be used for teaching networking protocols that were very different from those previously taught to students studying networking units. Examples of such different protocols are those used by home security devices. Although the main aim focus of this research was on improving teaching and leaning outcomes of necessity an understanding of the context of home security devices was also considered important and some a selection of these have been included in this paper. In an attempt to ascertain the effectiveness of SMDs for teaching home security device protocols a group of students who had previously studied computer networking via SMDs were introduced to a standard home security protocol and their opinions were subsequently sought as to whether the SMDs aided their learning and understanding of this protocol and the operation of the security device network demonstrated to them. The results of this research are presented in this paper.
