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
The workshop is intended for Doctoral students in the health and social sciences who are at the stage of developing a research proposal.
Moursund Mathematics Lecture Series. Dr. Jacob Lurie, Lecture 2: “Ambidexterity”
In classical algebraic geometry, there is often a stark difference between the behavior offields of characteristic zero (such as the complex numbers) and fields of characteristic p (such as finite fields). For example, the equation x^p = 1 has p distinct solutions over the field of complex numbers, but only one solution over any field [...]
Internationalizing the Curriculum: Champlain College and the Global Module Project
Champlain College, a leader in both online and international education, uses the Internet to create Global Modules that link the students and faculty at two or three international educational institutions for shared online readings, discussion and teamwork. Students at Champlain have used the Global Modules format to discuss womens issues with students in the U.A.E., terrorism with Jordanian students, globalization with Indian students, the peace movement with Austrian students and the Lebanon
Freshman Organic Chemistry
This is the first semester in a two-semester introductory course focused on current theories of structure and mechanism in organic chemistry, their historical development, and their basis in experimental observation. The course is open to freshmen with excellent preparation in chemistry and physics, and it aims to develop both taste for original science and intellectual skills necessary for creative research.
Physics learning with a computer Algebra systems: Towards a learning environment that promotes enhan
To become proficient problem-solvers, physics students need to form a coherent and flexible understanding of problem situations they are confronted with. This is important both for solving problems and for interpreting solutions. Still, many students have only a limited representation of the problems they are working on. Therefore, we devised an instructional approach to promote students' understanding of these problems, and to support them in forming associations between problem features and so
Stagecast Creator and Webct: An integrated use of computer programming and a virtual learning en
This paper reports on an effort to use Stagecast Creator as a means for developing modelling skills among undergraduate students taking an introductory course in science that took place in a virtual learning environment (WebCT). An inquiry-based curriculum was implemented, which guided students working in small groups to collect and study moon observations and construct a series of successive models of the moon phases using Stagecast Creator. Students reflective journals and reports of s
Functioning in the Wireless Classroom
Code It! fosters mathematics learning environments where pre-algebra students use handheld technologies to explore and learn about functions. The resources developed - server-based and handheld software and paper-based student and teacher texts - were packaged as a 20-session unit on code making and breaking and designed to boost students' understanding of functions and their facility with the multiple representations of tables, graphs and symbols. We field tested the wireless system with two te
This is a nonmathematical physics textbook, designed so that it can be used either for a semester-length course of the type popularized by Hewitt, or for a shorter course of 8 or 10 weeks. This book is essentially a rewritten version of Discover Physics. The rewrite is intended to do two things: (1) make the book less closely tied to a particular method of teaching, and (2) make it possible to use the book in shorter courses (such as Fullerton College's Physical Science 103A) with the omission o

The Complexity of Distributed Collaborative Learning: Unit of Analysis
The problem area of this paper is manifested in the new conditions that characterise distributed collaborative learning. The core argument is that distributed collaborative learning implies an interconnected complexity that can only be properly understood by extending the unit of analysis from technology and pedagogy themselves to real-life social contexts in which networked computers are being used. Experiments and small-scale field trials are only steps towards a deeper understanding of how co
Determining the Sources of Delay in a Distributed Learning Environment
In the context of LeGE-WG we expect to see the Open Grid Services Architecture (OGSA) being used as a guiding framework for the future deployment of Distributed Learning Environment (DLEs). OGSA is totally service-oriented and it has been known for sometime that Quality of Service (QoS) is key to the success of DLEs. Delay in particular, as experienced by the end user, is one of the key QoS parameters for a DLE. This paper describes techniques for identifying sources of such delay, and a model f
Studying participation networks in collaboration using mixed methods
This paper describes the application of a mixed-evaluation method, published elsewhere, to three different learning scenarios. The method defines how to combine social network analysis with qualitative and quantitative analysis in order to study participatory aspects of learning in CSCL contexts. The three case studies include a course-long, blended learning experience evaluated as the course develops; a course-long, distance learning experience evaluated at the end of the course; and a synchron

Implementation of ICT in Higher Education as Interacting Activity Systems
Implementation of ICT in higher education is not a trivial process. It is however a process leading to a number of challenges and problems. The paper develops a theoretical model of the implementation of ICT in higher education based on activity theory and on a case study in a Danish university. The model suggest that implementation in itself is an activity system. The implementation activity is composed of three processes: Selection of ICT; adaptation of ICT and change of practice with ICT.
