Learners engaged in informal learning tasks often find sharing their learning experience to be helpful. Informally, a learning experience describes what a learner has done, with what learning resources. We explore technological issues in a semantic web driven learning experience management architecture that supports collaborative learning, i.e., learning by reusing, sharing experience and build...

This paper investigates the state of programmed informal learning (e.g., team competitions, internships) in engineering education, the relevant research and available assessment instruments. Our purpose is to synthesize the existing informal learning research in engineering education for the engineering community, which should subsequently lead to the development of improved programs and learni...

Learning through observation in everyday activities is widely recognized in the ethnographic literature as a central way that children learn from others. There are two well-described characteristics of learning through observation: participation in meaningful activities with people who are important in the children’s lives and a belief that children are active, motivated learners who take initi...

This work describes our experiences on discovering association rules in medical data to predict heart disease. We focus on two aspects in this work: mapping medical data to a transaction format suitable for mining association rules and identifying useful constraints. Based on these aspects we introduce an improved algorithmto discover constrained association rules. We present an experimental se...

The field of education technology is embracing a use of learning analytics to improve student experiences of learning. Along with exponential growth in this area is an increasing concern of the interpretability of the analytics from the student experience and what they can tell us about learning. This study offers a way to address some of the concerns of collecting and interpreting learning ana...

This study investigated the impact of group discussions and question prompts on students’ vicarious learning experiences. Vicarious experiences were delivered to 65 pre-service teachers via VisionQuest, a website that provided examples of successful technology integration. A 2×2 factorial research design employed group discussions and question prompts as independent variables and students’ perc...

The desire to increase domestic revenue mobilization has made tax reform a priority for governments in many developing countries. Addressing the tax problem, however, is often a complex process that involves reforming the tax system, as well as setting up effective administrative structures to administer that system. Many see the revenue authority (RA) model as the solution to these problems. D...

To use deep reinforcement learning in the wild, we might hope for an agent that would never make catastrophic mistakes. At the very least, we could hope that an agent would eventually learn to avoid old mistakes. Unfortunately, even in simple environments, modern deep reinforcement learning techniques are doomed by a Sisyphean curse. Owing to the use of function approximation, these agents even...
