This article is devoted to some of the educational quandaries stemming from the fact that mathematics is a discourse that creates its own objects. More specifically, we ask how the participants of classroom learning-teaching processes cope with the seemingly paradoxical situation in which they are supposed to talk about objects, of the existence…

The view of learning as a particular type of the activity of communicating with others and with oneself has already been shown to unify the once separate lines of study devoted to cognitive and to social aspects of learning. This approach is now extended so as to include the study of affect. In this article, emotional expressions are treated as an…

Although the question of whether written curricula are implemented according to the intentions of curriculum developers has already spurred much research, current methods for documenting curricular implementation seem to be missing a critical piece: the mathematics. To add a mathematical perspective to the discussion of the admittedly…

Taking as the point of departure the vision of school algebra as a formalized meta-discourse of arithmetic, we have been following five pairs of 7th grade students as they progress in algebraic discourse during 24 months, from their informal algebraic talk to the formal algebraic discourse, as taught in school. Our analysis follows changes that…

The purpose of the study reported in this article is to examine the impact of curriculum on instruction. Over a three-year period, we observed 579 algebra-related lessons in grades 6-8. Approximately half the lessons were taught in schools that had adopted a "Standards"-based mathematics curriculum called the Connected Mathematics Program (CMP),…

Cultural-Historical Activity Theory (CHAT), which had been termed the best-held secret of education about 15 years ago, has had an exponential growth over the past three decades. Because it thematizes largely the structural aspects of activity systems, the theory only recently has been developed to include emotional, motivational, and…

While school bullying in Japan, Ijime, has been a topic of major public concern since the 1980s, few qualitative studies have been conducted to examine its nature and correlates. Through a case study of 30 ninth graders in a Japanese middle school, the study found that Ijime has complex group dynamics in its onset and process. The analysis of…

Collaborative peer learning environments have received increasing attention in classrooms due to the potential for improving learning and achievement. Yet previous research shows that not all students benefit from the collaborative experience. This paper explores the nature of helping behavior within peer-directed small groups that may be most…

As one of the popular and promising instructional technologies, Internet is playing a more and more important role in educational field all over the world. Bringing Internet into classrooms is encouraged in many countries; however, their policy initiatives to achieve this vary. The present paper is an empirical and exploratory study, trying to…
