This paper reports on a case study with three dyads of high school students (age 14 years) each collaborating on a plant growth modeling task in the computer-supported educational environment "ModelsCreator". Following a qualitative line of research, the present study aims at highlighting the ways in which the collaborating students as well as the…

Social technologies such as Weblogs, wikis, and social bookmarking are emerging both as information resources and as tools for research. This paper reflects on these technologies and suggests they may be well placed to build fluency in the higher-order thinking skills outlined in various information literacy frameworks, particularly in an…

Ethnomethodology is the analytical frame used here to recover embedded cultural discursive phenomena in the language of "at risk" middle-school boys as they talk about "computer games" and "schooling". What emerges is a rich picture of myths and heroes, identities of participation where member values and a discernible moral order are part of the…

The purpose of this study was to identify predictors of competence among adolescents with learning disabilities (LD) who participated in a virtual supported self-advocacy programme within the risk and protective paradigm. The sample consisted of 374 adolescents with and without learning disabilities, students of the 7th to 9th grades, at 15…

The objective of the research presented here was to study the influence of two types of instruction for using an argumentation diagram during pedagogical debates over the Internet. In particular, we studied how using an argumentation diagram as a medium of debate compared to using an argumentation diagram as a way of representing a debate. Two…

We present two case studies of two different pedagogical tasks in a Computer Assisted Language Learning environment called Grim. The main design principle in Grim is to support "Focus on Form" in second language pedagogy. Grim contains several language technology-based features for exploring linguistic forms (static, rule-based and statistical),…

Learner corpora, electronic collections of spoken or written data from foreign language learners, offer unparalleled access to many hitherto uncovered aspects of learner language, particularly in their error-tagged format. This article aims to demonstrate the role that the learner corpus can play in CALL, particularly when used in conjunction with…

This study introduces a new computer-based methodology, "concgramming", that has as its primary aim the automatic identification of the phraseological profile and hence the "aboutness", of a text or corpus. It is argued that this methodology can be employed by language learners and teachers to raise awareness of the importance of the…

Anyone who has ever tried to surf knows that it is not easy to actually catch a wave. A person has to paddle the surfboard out to where the waves are and work on his/her timing and paddle fast enough to catch the wave. In this article, the author chooses the surfing metaphor in accordance with the theme of the 2006 CALICO conference at the…

This article reports on a small-scale research project (n = 56) that investigated student educational gain. For the purposes of this study, gain is defined as an increase in the score that students obtain for pre/post intervention tests. Students received authentic exposure to the process via a web-delivered problem-based scenario. The students…

Individual or group presentations are common assignments in business communication courses, and many students use PowerPoint slides as audiovisual support. Frequently, curriculum constraints don't allow instructors much time to teach effective design and delivery of presentation graphics in their courses; guidelines in the form of minilectures or…

Web-based software was used to deliver and record the effects of programmed instruction that progressively added formal prompts until attempts were successful, programmed instruction with one attempt, and prose tutorials. Error-contingent progressive prompting took significantly longer than programmed instruction and prose. Both forms of…

In current curriculum materials for middle school students in the US, data and chance are considered as separate topics. They are then ideally brought together in the minds of high school or university students when they learn about statistical inference. In recent studies we have been attempting to build connections between data and chance in the…

The effectiveness of two different laboratory techniques is compared to teach students majoring in science in a general chemistry laboratory. The results demonstrated that student laboratory activities with computer-interface systems could improve student understanding.

Not all demonstrations involve using exciting visual displays of one or a series of scientific principles. Demonstrations can be as simple as showing the interrelationship between scientific concepts or principles using concept maps. Concepts maps are tools that help people conceptualize and remember a conglomeration of facts making up complex…
