Normalising Geometrical Constructions: A Context for the Generation of Meanings for Ratio and Propor
This paper describes aspects of 13 year-oldsÂ’ activity in mathematics as emerged during the implementation of proportional geometric tasks in the classroom. Pupils were working in pairs using a piece of software specially designed for multiple representation (symbolic and graphical) of the variation in parametric procedures with dynamic manipulation of variable. In this paper we discuss childrenÂ’s use of normalising, an activity in which children Â‘correctÂ’ the geometrical figures while devel

An examination of two types of timeline, linear vs. staggered: a mixed method approach
This study conducted as follow-up study to evaluate effects of two different time-based interfaces, linear and staggered. This study also tries to reveal usersÂ’ preferences when they look for information in two different computer-based timeline. Explanatory mixed method design was implemented. In the first part, quantitative, there were 42 subjects. Results shows no significant difference between two types of computer-based time-line in terms of task completion time and answer accuracy. In the

Internet Scout Project
The Black Hole Gang Web site is authored by fifth grade teacher Stephen Kramer and illustrated by Richard Torrey. The main page of the site contains pictures of the five members of the gang, which, when clicked, bring up another scene with the character in a room with various objects such as a rock collection, map, chemistry set, poster of Albert Einstein, telescope, and other science related items. Once an item is chosen, students read a brief description of it and can explore a variety of info

The Understanding the Universe Web site is part of Discovery.com's excellent educational resource DiscoverySchool.com site and is a joint effort with the American Museum of Natural History. This attractive site contains three major sections. The It's Awesome page has a time line of the universe that links to the Universe in One Year page -- a great way of learning the difficult concept of geologic time by showing that, if the history of the universe was compressed into one year, modern humans wo

Investigating human computer interaction issues in designing efficient virtual learning environments
Today, when an enormous number of computer-based systems exist, the human activities are being computer mediated. Usually, in designing the interface to those systems, the human-computer interaction is left behind without consideration. In this paper, a literature in human-computer interaction is to be reviewed and the technology aspect of human computer interaction is to be analyzed. Also, general design principles are to be reviewed. According to all these issues, recommendations to designing

Scripting argumentation in technology enhanced learning: a proposed system architecture
Argumentative knowledge construction is an important component of critical thinking. Learners who collaboratively argue about a subject can potentially develop domain knowledge and have the opportunity to use evidence critically in order to make sense of the subject under consideration. Moreover learners have to take into account claims and evidence of each other during argumentation and in this way they develop mental models for argument construction and sequence. However, research indicates th

Making the History of 1989: The Fall of Communism in Eastern Europe
Making the History of 1989 materials were developed because teachers and their students have little access to vivid historical documents in English that convey the epochal events of 1989. Project materials utilize recent advances in our understanding of how historical learning takes place, including complex interaction with sources, recursive reading, and skills used by historians. The site has three key features: a substantial collection of high quality primary sources; a set of multimedia int

Obstacles to the development of conceptual understanding in observational astronomy: the case of spa
Simple everyday phenomena like the day - night cycle and the sequence of four seasons are taught at the higher level of elementary education and the lower level of secondary education in Cyprus. Even though there is no specific subject dedicated to Astronomy or spatial reasoning, the day Â– night cycle, the sequence of the four seasons and the sequence of the lunar phases are part of the national curriculum of Geography. For this reason, the construction of conceptual understanding in basic Astr

Toward Computer-Based Support of Meta-Cognitive Skills: a Computational Framework to Coach Self-Expl
We present a computational framework designed to improve learning from examples by supporting self-explanation Ã¶ the process of clarifying and making more complete to oneself the solution of an example. The framework is innovative in two ways. First, it represents the first attempt to provide computer support to example studying instead of problem solving. Second, it explicitly coaches a domain-general, meta-cognitive skill that many studies in cognitive science have shown to greatly improve le

Internet Scout Project
In this Daily Lesson Plan from the New York Times Learning Network, students explore a variety of drought-related issues and research possible courses of action as part of a "drought preparedness taskforce." Based on New York Times coverage of drought in Arizona (story link provided), this exercise offers an active, interdisciplinary way to learn about water conservation and the ecological and economic effects of drought. Designed for grades 6-8 or 9-12, this exercise can be completed in one cla

Verbal and Nonverbal communication in computer mediated settings
The paper discusses the verbal and nonverbal communication during a video-recorded meeting between two physically separate teams as part of a 9 month multi-site construction project. In the extract analysed here, the team which was video-recorded contained three members and the project coordinator, whereas the remote team contained a single individual. Communication between the two teams was by means of telephone and shared computer meeting system. The video-recorded team used nonverbal communic

Aspects of Speech Act Categorisation: Towards Generating Teachers' Language
In this paper we examine a possible method for classifying speech acts produced by human teachers, with a view of informing the designs of intelligent natural language tutors and of providing the basis for a formal analysis of the effects that teachers' language has on students' learning. We argue that traditional means as initiated by the Ordinary Language Philosophers such as Austin (1962), Grice (1975) and Searle (1979) are not sufficient to account for all types of linguistic phenomena occur

LaCOLLA: Middleware for Self-Sufficient Online Collaboration
The LaCOLLA middleware makes it possible for collaborators to interact using their own resources and not depend on a centralized regime. By contributing their own resources, group members can organize and communicate using a federated peer-to-peer model. Utilizing LaCOLLA middleware, the group can function regardless of whether a member removes resources and despite network or node failures or disconnection. This capacity for self-organization, together with location transparency, lets applicati
