The Discrepancy Evaluation Model: A Strategy for Improving a Simulation and Determining Effectiveness.
Morra, Linda G.
This paper presents the Discrepancy Evaluation Model (DEM) as an overall strategy or framework for both the improvement and assessment of effectiveness of simulation/games. While application of the evaluation model to simulation/games rather than educational programs requires modification of the model, its critical features remain. These include: (1) the comparison of a standard to performance and identification and resolution of discrepancy information; (2) the recognition of evaluation stages which encompass planning, implementation, monitoring and assessment functions; (3) the concept of stage recycling; and (4) the development of a design and evaluation plan for each stage. Discrepancy information is important in each of four evaluation stages: pre design, design, input/process, and output. Each stage requires the comparison of standards to performance, that is, a discrepancy analysis. Borrowing from systems analysis concepts, standards are operationally defined as input (resources), process (activities), and output (objectives). An evaluation plan is also developed for each stage to raise evaluation concerns, formulate questions, select measurement instruments, and specify the criterion for satisfactory performance. The appendix includes two measurement instruments. The first is a guide to classifying simulations, and assessing the advantages and disadvantages of the selected format against the developer's objectives. The second is a ten-item rating scale incorporating eight concepts which the literature indicates are important in determining the face validity of a simulation. (Author/CP)
