“Come on guys, use your sense!” Illuminating the ‘incarnate’ work of teaching - Koshmann

Twelve years ago, Lehrer and Schauble rolled out a newly-designed math and science curriculum in a particular 5th gradeclassroom (Lehrer & Schauble, 2004, 2011). In this talk, I will examine a brief fragment of interaction recorded in this classroom.The participants observed here are trying to work out how to graphically represent a set of data.

A Design-Based Research Approach to Understanding Complex Learning - Hmelo silver

Complex learning environments require complex approaches to understanding both what and how students learn. In this talk, Iwill describe design-based research methodology and discuss how I have used this approach to understand learning intechnology-rich learning environments. One example will show how research on expertise in complex systems led to the designof a technology-rich learning environment for middle school science classrooms. This program of research used a combinationof laboratory and classroom research. Time permitting, a second example will bring together research on problem-basedlearning that went from quasi-experimental research showing what students learned to more qualitative research that explainshow students learn.
