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 [...]

Model-based Design of Activity Spaces for Collaborative Problem Solving and Learning
It is investigated how the design of external representations, namely, concept maps, can be based on a simulation model, how model-based concept maps can be utilized in an instructional and collaborative problem solving setting and how they can be taken advantage of in a computerized environment for collaborative problem solving and learning. With respect to the first goal, we made use of a cognitive simulation model to develop two instructional units. One unit teaches qualitative aspects of cla

Using Interaction Analysis to reveal Self-Regulated Learning in Virtual Communities
Aim of this paper is to analyse whether Interaction Analysis can help investigate the practice and development of Self-Regulated Learning (SRL) in Virtual Learning Communities (VLC). Interaction analysis is increasingly used to study learning dynamics within online activities. It proceeds by searching expressions that reveal the aspects under study in the written messages exchanged by the learners. To this end, we devised and classified a number of indicators suggesting the existence of self-re

Learning Bridges: a role for mobile technologies in education
A project called MyArtSpace, funded by the UK Department for Culture Media and Sport, is today exploring how children can engage in similar enquiry-led learning supported by mobile technology and how this can link to school and home learning. Using MyArtSpace as an example, we discuss the possibilities for mobile technology to form bridges between formal and informal learning. We also offer guidelines, drawn from our experience with MyArtSpace, for designing such bridges.

Blended Learning Technologies in Lifelong Education: Lessons Learned from a Case Study
The combination of the traditional form of education and e-learning activities (blended learning) constitutes an important possibility for the higher education, so that they reach the flexibility which is considered to be necessary for their adaptation to the trainees’ needs within the frame of socio-cognitive needs created by the information society. We present the principles of the application of blended lesson designs in graduate level and of its evaluation by the students. Based on our expe

Bridging the Contextual Distance: The e-CASE Learning Environment for Supporting Students’ Context
Supporting students’ awareness of the complex way that contextual issues affect knowledge application in authentic situations is a critical instructional mission and can lead to improved problem solving in the workplace. In this work we present the design of e-CASE (Context Awareness Supporting Environment), which is a case based learning environment for supporting instruction in the domain of software development. In designing e-CASE we employ a model for context which further guides the use o

Collaboration Load
Does collaboration increase or decrease cognitive load during learning? On one hand, collaboration enables some degree of division of labour that may reduce cognitive load. On the other hand since interacting, expressing thoughts, monitoring another’s understanding, grounding, etc., are mechanisms inducing some extraneous cognitive load, they may create cognitive overload and impede learning mechanisms. However this additional load may explain why collaboration sometimes leads to knowledge cons

Contextualizing Discussions in Distance Learning Systems
In distance learning systems, communication tools are rarely integrated into learning activities, which does not encourage their use. The main goal of our work is to mitigate this lack of integration. Our aim is to bring the discussion activities closer to the learning activities, i.e. to situations to which the discussions must ideally relate to in order to promote learning between students. Thus, we suggest two models of forum which are contextual and based on a structuring of discussions resp

Giving teachers a hand(book) to develop ict-enhanced skills
Shared web-based knowledge bases, enriched with the possibilities of discussing about their content and of proposing new one, seem to offer the opportunity to diffuse pedagogical innovation. To this aim, the knowledge base should enable teachers to put their own ideas at colleagues’ disposal; and moreover, to improve their pedagogical knowledge by availing themselves of colleagues’ proposals and suggestions. Thus, personal growth evolves in shared knowledge and vice-versa, facilitating the for

Electronic sensors exist in many facets of our lives, from measuring operating conditions of our vehicles to adjusting the temperature of our homes. They can even mean the difference between life and death when used to monitor patients in emergency rooms. Even though sensors work transparently in their multitude of functions, their importance cannot be understated.Sensorland (1) has basic descriptions of a wide variety of sensors and related concepts. Out of the 50 items in the list, some have f

An Intelligent SQL Tutor on the Web
The paper presents SQLT-Web, a Web-enabled intelligent tutoring system for the SQL database language. SQLT-Web is a Web-enabled version of an earlier, standalone ITS. In this paper we describe how the components of the standalone system were reused to develop the Web-enabled system. The system observes students' actions and adapts to their knowledge and learning abilities. We describe the system's architecture in comparison to the architectures of other existing Web-enabled tutors. All tutoring

The Logic-ITA in the classroom: a medium scale experiment
This paper presents the experiment and consequent evaluation of introducing the Logic-ITA in a second year tertiary undergraduate class. The Logic-ITA is a web-based Intelligent Teaching Assistant system, aimed at alleviating some of the problems caused by large classes or distance learning. Its domain of application is the construction of formal proofs in logic. The system acts as an intermediary between teacher and students: on one hand, it provides students with an environment to practice for

The impact of simulator-based instruction on the diagramming of the interaction of light and matter
We examine the conceptual development resulting from an instructional experiment with an interactive learning environment in geometrical optics for introductory high school physics. How did teaching-learning processes come to change the ways in which students depicted various everyday optical situations in paper and pencil graphical representations? We view conceptual development as a process resulting in part from increasingly aligning one's practices to a target community by means of participa
