Language competence in various communicative activities in L2 largely depends on the learners' size of vocabulary. The target vocabulary of adult L2 learners should be between 2,000 high frequency words (a critical threshold) and 10,000 word families (for comprehension of university texts). For a TOEIC test, the threshold is estimated to be…

Lexical competence constitutes a crucial aspect in L2 learning, since building a rich repository of words is considered indispensable for successful communication. CALL practitioners have experimented with various kinds of computer-mediated glosses to facilitate L2 vocabulary building in the context of incidental vocabulary learning. Intentional…

The aim of this study is to optimize CALL environments as a learning tool rather than a gloss, focusing on the learning of polysemous words which refer to spatial relationship between objects. A lot of research has already been conducted to examine the efficacy of visual glosses while reading L2 texts and has reported that visual glosses can be…

This research was conducted as part of Project CIRCLE, a collaborative project between the University of Texas at Austin College of Education, the Austin Independent School District, and the Eanes Independent School District. The intent of the project was to establish collaborative knowledge-building communities in high school classrooms among…

This is a discussion about the role of a case or authentic scenario in an online learning environment. Using authentic cases for intentional learning promotes effective, cognitive, and affective transfer between learning space and performance space. Creating an online case event provides an opportunity for learning design professionals to use…

The effects of visual grouping strategies involving animated and static graphic presentations on learning were studied. Also studied was the ability of students to learn a scientific rule presented incidentally in an animated sequence in the hope of replicating results from previous research. A total of 39 fourth graders participated in an…

Computer Supported Intentional Learning Environments (CSILE) is a project using computer software to promote the constructive processes involved in intentional learning. CSILE enables groups of students to build a collective database (knowledge base) of their thoughts, in the form of pictures (created by students using a color graphics editor) and…

Influenced by generative and intentional learning environment strategies and tools, a World Wide Web-based tool has been developed to empower learners to build their own Web-based Performance Support System (WPSS) to support learning, professional development, and performance within a domain. Enabling learners to develop their own WPSS…

The purpose of this study was to investigate the effect of implementing cooperative learning and objectives with computer-based instruction (CBI). Subjects were 125 fifth and sixth grade students. Cooperative dyads and individuals worked through a CBI earth science program that contained either instructional objectives, advance organizers, or no…
