A Bayesian Student Model without Hidden Nodes and Its Comparison with Item Response Theory
The Bayesian framework offers a number of techniques for inferring an individual's knowledge state from evidence of mastery of concepts or skills. A typical application where such a technique can be useful is Computer Adaptive Testing (CAT). A Bayesian modeling scheme, POKS, is proposed and compared to the traditional Item Response Theory (IRT), which has been the prevalent CAT approach for the last three decades. POKS is based on the theory of knowledge spaces and constructs item-to-item gra

A New Analytical Approach on Continuous Improvement Evaluation: A National Presentation Case
This paper demonstrates a new approach on how to analyze evaluation data to find a teams (sometimes called circle) improvement ability and the characteristics of evaluators by using the data from the national Quality Control Circle (QCC) presentations in Taiwan. Most evaluations on the QCC presentation use the itemized rating method or the duplex-pole evaluation method. The former has the negative effects of canceling out the higher and lower while the latter cannot distinguish the ability typ
ePortfolios in Education - Learning Tools or Means of Assessment?
ePortfolios are collections of electronic evidence which capture the idea of lifelong learning ePortfolios at school can support the documentation of competences better than normal tests and assessments. The acquired competences may further be transfered from school to the world of work. On the other hand ePortfolios are powerful tools for learning and reflecting.

Evaluating Wiki as a tool to promote quality academic writing skills
In this study we investigated undergraduate teacher trainees' use of wikis, focusing on the use of shared spaces to communicate ideas and generate course specific content. We explored how students, through such activities, were to able to improve their academic writing skills. We discuss writing as a social practice and discuss how wikis might promote better academic writing. With data derived from student discussion boards and a post-module e-mail questionnaire (N=35) our findings indicate that

What's Air Got to Do with It?
Students are introduced to the concepts of air pollution and air quality. The three lesson parts focus on the prerequisites for understanding air pollution. First, students use M&Ms to create a pie graph that expresses their understanding of the composition of air. Next, students watch and conduct several simple experiments to develop an understanding of the properties of air (it has mass, it takes up space, it can move, it exerts pressure, it can do work). Finally, students develop awareness an

Embedded Training for Complex Information Systems
One approach to providing affordable operator training in the workplace is to augment applications with intelligent embedded training systems (ETS). Intelligent embedded training is highly interactive: trainees practice realistic problem-solving tasks on the prime application with guidance and feedback from the training system. This article makes three contributions to the theory and technology of ETS design. First, we describe a framework based on Normanâs "stages of user activity" model for d
Combining heuristics and formal methods in a tool for supporting simulation-based discovery learning
This paper describes the design of a tool to support learners in simulation-based discovery learning environments. The design redesigns and extents a previous tool to overcome issues that came up in a classroom learning setting. The tool focuses on supporting learners with experimentation to identify or test hypotheses. The aim is not only to support learning domain knowledge, but also learning discovery learning skills. For this purpose the tool uses heuristics and formal methods to assess the

Many factors impact learning; the environment and resources available, the domain, how much prior-knowledge a student has, and how well they make use of their metacognitive skills, all of these factors impact new knowledge creation. The series of studies described in this dissertation focuses on the latter; i.e. the metacognitive skillfulness of students. Known collectively as self-regulation, planning, monitoring, and evaluation, when applied appropriately will enhance learning. Students who m
