Groupware is often regarded as an important tool for facilitating team collaboration. However, most theoretical findings are obtained by using students as subjects. We are interested in knowing the practicability of groupware embedded in a professional community of practice. To gain insights into the reality of knowledge sharing and creation through collaborative technologies in a real setting,...

The aim of the report is to set forth recommendations for bringing about significant improvement in the mathematical education of future teachers. The project to produce the report was supported by a grant from the U.S. Department of Education. The members of t...

This paper extends Emmanuel Levinas’ articulation of “the face to face” encounter (1969, p. 79-81) to suggest that students and teachers can be brought into an ethical proximity created by the media they share and discuss online in Facebook. In Levinas’ terms, a ‘face’ is not simply a physical face. Instead, the Levinasian face encapsulates all the ways that one person is able to reveal aspects...

Understanding an arithmetic operation implies, at minimum, knowing the direction of effects that the operation produces. However, many children and adults, even those who execute arithmetic procedures correctly, may lack this knowledge on some operations and types of numbers. To test this hypothesis, we presented pre-service teachers (Study 1), middle school students (Study 2), and math and sci...
