Existing research is unclear on how to generate lessons learned for defect prediction and effort estimation. Should we seek lessons that are global to multiple projects, or just local to particular projects? This paper aims to comparatively evaluate local vs. global lessons learned for effort estimation and defect prediction. We applied automated clustering tools to effort and defect data sets ...

Lessons learned systems are knowledge management solutions that serve the purpose of capturing, storing, disseminating and sharing an organization’s verified lessons. In this paper we propose a two-step categorization method to support the design of intelligent lessons learned systems. The first step refers to the categories of the lessons learned processes the system is designed to support. Th...

A requirement to support teachers’ professional vision for highperformance classrooms is to clarify criteria for analyze data collected from classroom. Plans of lessons can be a criterion for it because teachers can figure out and compare what are the plans for and what is happening in the lessons. This paper discusses the contribution of modeling plans of lessons based on ontological engineering.

Lessons learned processes have been deployed in commercial, government, and military organizations since the late 1980s to capture, store, disseminate, and share experiential working knowledge. However, recent studies have shown that software systems for supporting lesson dissemination do not effectively promote knowledge sharing. We found that the problems with these systems are related to the...

Since Skinner’s distinction between the science of learning and the art of teaching, it is an unanswered question whether the ability to teach and to plan lessons is based on learning by advice or on special dispositions of the teachers. We therefore addressed the question whether a creative disposition of instructional design students has effects on their designs of lessons. We conducted a stu...

The purpose of this document is to develop an understanding of the components of a lesson learned process and how they fit together from the perspective of the Joint Center for Lessons Learned (JCLL). We also discuss the status of the JCLL, its lessons learned products, and provide a roadmap for what activities JCLL should support, including nearand long-term goals. Throughout we stress the pot...

Lessons learned systems are a common knowledge management initiative among the American government (e.g., Department of Defense, Department of Energy, NASA). An effective lessons learned process can substantially improve decision processes, thus representing an essential chapter in a knowledge sharing digital government. Unfortunately, these systems typically fail to deliver lessons when and wh...

Recent research has suggested that differences between intelligent tutor lessons predict a large amount of the variance in the prevalence of gaming the system [4]. Within this paper, we investigate whether such differences also predict how much students choose to go off-task, and if so, which differences predict how much off-task behavior will occur. We utilize an enumeration of the differences...
