Opportunity Initiated Systems Design

This paper proposes a design theory of how opportunities might be used to facilitate change within a system, particularly an educational system. Opportunity Initiated Systems Design (OISD) is a system design model that retains the values and goals of Idealized Systems Design (ISD) yet incorporates other models of systemic change to form a simpler, more practical theory of systems design. Traditional barriers to ISD are discussed, used as the basis for describing suggest an alternative theory of systems design. The paper articulates the values and goals of OISD and outlines a theory of OISD. The six phases of OISD are presented, including specific guidelines for implementing OISD. Limitations of OISD and implications for further research are discussed.

Opportunity Initiated Systems Design: A Case Study

The field of Instructional Systems Design (ISD) provides models from which instructional changes can be designed and implemented. In ISD programs, students develop skills in the application of this process and apply these skills in a variety of settings. Although our models also provide a framework from which program change can proceed, few examples exist of the application of ISD to the design of an educational system (Squire, 1999). In this paper we describe the application of Opportunity Initiated Systems Design, apractitioner-based ISD model, in light of our own formative evaluation and program revision of the Instructional Design and Technology program at the University of Iowa. In this case study, we found that the communication of shared definitions was critical and that the probabilistic nature of the model was not a limitation but rather a prompt for further opportunities.

基于知识重用的设计体系与应用

传统的基于实例重用的设计方法中对设计知识的处理与组织能力不足，没有建立有效的机制保障设计知识的可重用性。本文提出了基于知识重用的设计体系，其原理是通过对不同层次知识的表达、组织以更有效地实现设计方案、设计过程及设计知识的重用。该体系能更好地重复利用以往的设计知识与经验，从而提高设计效率。文中给出了该体系中不同环节的表达及求解模型，并给出了应用实例。
