Divided into two parts, this article analyzes why some pupils feel reserve about instantaneous velocities and instantaneous flows. The second part relates reactions of pupils facing a problem that implicates the instantaneous rate of change. Describes some characteristics of this problem that enables the authors to explain its instructional…

This book is the result of the accumulated research of five researchers from the United States and Australia on a school in Coastal Australia. The research team shared a constructivist epistemology and interpreted the qualitative and quantitative data collected over a 10-week period in two classrooms from that perspective. Each chapter discusses…

A new framework for designing qualitative studies is described to optimize the emergence, representation and presentation of insights. The framework, called Reflection Methodology, is presented as a "Conversational Paradigm" that includes four components--interviewer (researcher as participant); child, task situation, and observing…
