Current debates about successful mathematics pedagogy suggest that mathematical learning and problem solving can be enhanced by using metaphors as they provide students with a tool for thinking. But assisting pre-service teachers to understand the importance of careful and accurate explanations for mathematical concepts remains an issue. This…

Situated within the framework of the systemic-functional linguistics (Halliday, 1994) and language-based theory of learning (Halliday, 1993), this article examines a shift toward a more objectified and "scientific" representation of reality in texts written by foreign language (FL) learners at various levels of acquisition.

These hypotheses combine characteristics of both rigorous and metaphoric language. Since the computer demands explicit instructions for each step in the evolution of the automaton, such models can reveal conceptual…
