Do you regularly reflect on the value you bring to your client? The act of reflection is something experienced consultants, both internal and external, consistently do in their practice. This article examines the ways in which Certified Performance Technologists (CPTs) define and recognize the success of their efforts, but most importantly, how they learn from engagements that do not always end with the desired outcome. You will hear from CPTs across several industries in their own words about what strategies they have employed to continue to improve their skill sets.  相似文献

This case study examines the design practices of instructional design (ID) students while working on a realistic design project (Joel, 1987) to explore whether ID students make design judgments; how, when, and where they are making them; and what kinds of judgments they make during a realistic instructional design process. The perspective taken in this study is that design judgments comprise multiple, complex types and are not confined to moments of overt decision making (Nelson & Stolterman, 2012). In this small‐scale case study, a group of students was observed in the process of designing instruction within a semester. The findings of the study suggest that these ID students continuously made design judgments of many kinds throughout the design process.  相似文献

In 1988, two staff members in the design department at Motorola Training and Education Center (MTEC) began a self-initiated project to develop and implement a system to improve the quality of courses being developed for their customers. This article describes how they applied Motorola's six steps to Six Sigma quality to their instructional design activities. While their quality system was not institutionalized throughout the instructional design department, several valuable lessons were learned that might benefit others embarking on a similar endeavor. Lessons learned dealt with: the sample of customers used to determine customer requirements, product-specific customer requirements, a continuous improvement system within the context of an instructional systems design model, the level of organizational readiness, involvement of stakeholders, the role of rewards and recognition, and appropriate metrics.  相似文献

The release of the Old World Drought Atlas (OWDA) in November 2015 provides historians with an unprecedented glimpse into the climate of the medieval world. Through the careful examination of tree-ring data provided by the OWDA, historians can better gauge how the environment affected the course of medieval Mediterranean history, particularly in times and places where textual data is sparse, such as North Africa. The case studies of the Norman conquest of the coast of Ifrīqiyya in the 1140s and the invasion by the Banū Hilāl in the mid-eleventh century show the utility of the OWDA for gaining a better understanding the medieval Mediterranean. In particular, OWDA data shows that the arrival of the Banū Hilāl into Ifrīqiyya coincided with a period of extended drought that is not documented in the written sources and suggests that increased competition for scarce resources was instrumental to their entrance into the region.  相似文献
