System models are commonly used in tertiary education as a mechanism for describing the interacting components of educational phenomena, but have hitherto been uncritically accepted. This paper provides a critical review of existing systems models, including the 3P model defined Biggs, and outlines their conceptual challenges. A revised model developed for curriculum research is presented. The paper would be of interest to those undertaking educationfocused research, scholarly teaching practitioners as well as those with an interest in the use of systems models as a framework for educational alignment.
IntroductionEducational phenomena are characterised by enormous complexity in both the number of variables and the dynamic nature of their interaction over time. Navigation of this complexity when developing a research design is a difficult task, especially for the novice educational researcher or scholarly practitioner. In particular, identifying the boundaries of a topic for study and the connections between the multiple influences on educational events or outcomes can seem a daunting and unachievable task.Systems-based models have commonly been used as a means of managing data for educational phenomena as a topic of research or for improved practice (Biggs 1999;Doll 2008;Frederiksen 1989;Hicks 2007;Iannone 1995;Semetsky 2008). As a social system with multiple complex parts in constant flux and interaction with the environment, education epitomises the characteristics of a complex system (Hicks 2007). Systems models have been advanced to assist research and development relating to various aspects of learning and teaching, including curriculum design. In their paper on the application of systems theory as a conceptual framework in curriculum development, Chen and Stroup (1993) argue that systems approaches have great potential for the development of coherent explanations for educational events. They characterise some of the major strengths of systems approaches for education as:
