Using visualizations to teach problem-solving skills in mathematics: Which kind of visualization wor
In the experiment described in this paper we investigated the effects of different kinds of computer-based visualizations on the acquisition of problem-solving skills in the domain of probability theory. Learners received either purely text-based worked examples, text plus an instruction to mentally imagine the examples contents, or they could retrieve either static pictures or concrete animations that depicted the problem statement and the problem states achieved by applying a specific solut
Balancing situativity and formality: the importance of relating a formal language to interactive gra
A situated cognition theory is presented in which situated learning is viewed from a Vygotskian perspective: the developmental situativity theory. It is assumed that learning is basically a non-symbolic inductive process that is greatly enhanced by formal systems which act as tools. Instruction should provide students with an environment containing elements to allow for situated activity as well as with appropriate formal tools. Tarski's World, which is an instructional Interactive Graphical Rep
Understanding weblog communities through digital traces: a framework, a tool and an example
Often research on online communities could be compared to archaeology : researchers look at patterns in digital traces that members leave to characterise the community they belong to. Relatively easy access to these traces and a growing number of methods and tools to collect and analyse them make such analysis increasingly attractive. However, a researcher is faced with the difficult task of choosing which digital artefacts and which relations between them should be taken into account, and h
Towards a Generic Platform for Developing CSCL Applications Using Grid Infrastructure
The goal of this paper is to explore the possibility of using CSCL component-based software under a Grid infrastructure. The merge of these technologies represents an attractive, but probably quite laborious enterprise if we consider not only the benefits but also the barriers that we have to overcome. This work presents an attempt toward this direction by developing a generic platform of CSCL components and discussing the advantages that we could obtain if we adapted it to the Grid. We then pro
A Model for the Efficient Representation and Management of Online Collaborative Learning Interaction
This study aims to explore the importance of the efficient representation and management of the event information generated from group activity in online collaborative learning practices so that we can use it to provide awareness about individual and group behaviour. The achievement of this goal first involves the design of a conceptual model of collaborative learning interaction that structures and classifies the information generated in an online collaborative learning situation at several lev
Collaboration Activity Function: An interaction analysis tool for Computer Supported Collaborative
During the last years, an increased interest has been observed on tools analyzing collaborative interactions that could be useful for researchers, teachers, or even students. The paper presents such a tool, based on the formally defined collaborative activity function (CAF). The empirical evaluation of CAF is also presented. The evaluation is focused on teachers using CAF during and after sessions of synchronous collaborative problem solving among students.
Learning a New Game: Usability, Gender and Education
This research study aims to investigate the usability issues of a computer game; regarding how people learn a new game. Because the user characteristic and the strategies they use while learning a new tool are important factors for usability, they were also taken into account in the study. Both qualitative and quantitative methods were used in the study. 16 participants played the computer game. They were also observed and their eye-movements were recorded by an eye tracking device. Results show
Students' adaptation to a new situation:
the design of an experimental procedure
Different studies (Arce and Betancourt, 1997; Séré, 2002) emphasize the importance of the task of experimental procedure design in a learning context. However, the required design is a difficult task for students (Séré and Beney, 1997). Consequently, students are hardly ever allowed to design their own experiment. The study by Tiberghien et al. (2001) showed that to learn how to plan an investigation in order to address a specific question or problem was the least frequent process object
Effects of pictures, age and experience on learning to use a computer program
This study examines the effects of pictures of screen captures and input devices on documentation for older novices. There was no main effect of pictures, but there were statistically significant interactions between the type of picture and the factors of age and computer experience. As predicted, the most optimized designsthe ones presenting screen capturesmoderated the negative effects of age. We argue that screen captures help reduce two problems in the cognitive area that are especially
Internet Scout Project
The Shoesmith research group at the University of Western Ontario deals with problems in electrochemistry and corrosion studies. With the extensive use of images and figures, this website highlights over ten of the group's projects including kinetics of copper corrosion conditions and the chemistry of nuclear fuel under Canadian Waste Disposal Conditions. Researchers can read about and view the substantial facilities within the group's two main laboratories. The website features links to most of

Video-as-Data and Digital Video Manipulation Techniques for Transforming
Learning Sciences Research,
This chapter concerns the theoretical and empirical foundations and current progress of the Digital Interactive Video Exploration and Reflection (DIVER) Project at Stanford University. The DIVER Project aspires to accelerate cultural appropriation of video as a fluid expressive medium for generating, sharing, and critiquing different perspectives on the same richly recorded events and to work with others to establish a Digital Video Collaboratory (DVC) that enables cumulative knowledge building
Presents major nutritional problems that influence the health, survival, and developmental capacity of populations in developing societies. Covers approaches implemented at the household, community, national, and international levels to improve nutritional status. Explores the degree to which malnutrition can be prevented or reduced prior to achieving full economic development through targeted public and private sector interventions that address the causes of malnutrition.
Jack Miles: America, Islam and the 'ground zero mosque', at ANU
Professor Jack Miles of the University of California at Irvine gives this lecture entitled 'America, Islam and the 'ground zero mosque'' at The Australian National University on 9 September 2010. Plans to build an Islamic centre near the site of the 9/11 bombing have become a flashpoint for debate over the nature of America's relations with Islam. Eminent American religion scholar and journalist Professor Jack Miles argues that the conservative critics of the "ground zero mosque" are Osama bin

Ecological Footprint Teacher's Manual: Thinking Critically about Environmental Impacts throughout Hi
"Thinking Critically about Environmental Impacts throughout History" is a workshop developed for history and social studies teachers who want to incorporate the scientific and social aspects of using renewable resources into classroom teaching. Through the Ecological Footprint framework, educators learn how to help students understand cumulative environmental impacts. Redefining Progress developed the Ecological Footprint Teacher's Manual to make this curriculum available for self-paced training
What Would They Say?
This lesson allows students to utilize their previous knowledge to give a “voice” to the African-Americans in the news reels. This lesson is based on the understanding that students have already been exposed to news reel as primary source documents in the Social Studies classroom (this can be done in succession with Lesson #1 and #2 or as a stand alone lesson during African-American History Month or during another teacher-chosen unit). In addition, this lesson provides the teacher with two o
