The forecast for the first quarter of this century is that the issue of teaching science in the language to which the learner is most familiar will receive more attention in our quest to win more students for science. Over two-thirds of countries in Africa, Asia, and Europe have developed policies on the use of the mother tongue for teaching…

Teacher-fronted interaction is generally seen to place limitations on the contributions that learners can make to classroom discourse and the conclusion is that learners are unable to experiment with, for example, turn-taking mechanisms. This article looks at teacher-fronted interaction in the language classroom from the perspective of learner…

The current paper examines the discursive practices of one novice English as a Second Language (ESL) teacher "dealing with" learners' unexpected contributions in whole group classroom interactions during teacher- and learner-initiated sequences-of-talk. The study draws from two fields of research: classroom discourse studies…

The purpose of this paper is to present the mechanism for effective communication when the mathematical objects of learning are equations and functions. The presentation is based on data collected while the same object of learning is presented in two classes, and it includes two teachers and 45 students. Among other things, the data consists of…

As the number of immigrant students increases in U.S. classrooms, so have the challenges teachers encounter as they seek to be culturally responsive.

In this article the author addresses the issue, invoking post-Piagetian and neo-Vygotskian…

Technology offers many opportunities for educators to support teaching, learning and assessment. This paper introduces a project to design and implement a virtual environment (SAVE Science) intended to assess (not teach) middle school students' knowledge and use of scientific inquiry through two modules developed around curriculum taught in middle…

In this article we consider data arising from student-teacher-researcher interactions taking place in the context of an experimental teaching program making use of multiple modes of communication and representation to explore three-dimensional (3D) shape. As teachers/researchers attempted to support student use of a logo-like formal language for…

The aim of this study was to explore regular teachers' perceptions and experiences of supports and obstacles to communicative interactions for students with multiple and severe disabilities (MSD).

The article describes action research that followed the professional development process of teacher educators engaged in the role of workshop mentors. The inquiry into their own practice and discussions about pedagogical dilemmas proved to be ways of conducting self-study during the interactive team meetings. The goal of these meetings was to…

This article describes aspects of classroom discourse, illustrated through vignettes, that reveal the complex relationship between the forms in which mathematical objects exist and their ostensive representations. We illustrate various aspects of the process through which students come to consider the reality of mathematical objects that are…

Today, teachers and administrators are continuing to recognize that learning is a social function, and that students do indeed learn better when working with others. The author agrees with this concept, but she wants to sigh deeply when she hears of one more person or company who has marketed the best approach to collaboration in the classroom. In…

Chula Vista Elementary School District, the largest in California, dramatically raised its student achievement while taking on increasing proportions of English learners by focusing on what it calls teacher talk--the way lessons are developed, delivered, and executed.
