We argue that progress in the area of research on mathematics teacher responses to student thinking could be enhanced were the field to attend more explicitly to important facets of those responses, as well as to related units of analysis. We describe the Teacher Response Coding scheme (TRC) to illustrate how such attention might play out, and then...

The notion of practice-based teacher education has recently been offered to mitigate the long-standing tension between theory and practice in teacher education. In practice-based teacher education, preservice teachers study a core set of teaching practices by examining decompositions of practice and learn these practices through varied and multiple...

[Link to the full version: http://www.citejournal.org/vol14/iss4/mathematics/article1.cfm] This paper builds on Grossman's notion of approximations of practice as scaled-down opportunities for preservice teachers to learn to teach by doing. The authors propose the use of media rich, collaborative web-authoring tools for preservice teachers to creat...

Mathematical argumentation in classrooms has been linked with students’ increased understandings of and achievement in mathematics. A key component of mathematical argumentation is the teacher’s use of questioning strategies. In particular, effective questioning asks students to explain and justify their work and probes student understanding. Howev...

During a fluctuation electron microscopy (FEM) study of disordered carbons, we found that samples containing C(60) exhibit a normalized variance peak at 7.1 nm(-1) that appears to be a unique indicator of tight curvature in layered materials. This peak is associated with the characteristic in-plane carbon-carbon bond distance of approximately 0.14...

We describe some of the recent advances in the fluctuation microscopy technique for probing medium-range structural correlations in disordered materials. In particular we show that fluctuation microscopy is a surprisingly sensitive method for detecting trace quantities of C60 in a disordered graphite matrix. This surprising sensitivity arises becau...

Fluctuation electron microscopy (FEM) is a hybrid imaging-diffraction technique. This technique is particularly sensitive to paracrystalline structures of dimension 0.5-2 nm, which are difficult to detect by either imaging or diffraction techniques alone. It has been successfully deployed to study paracrystalline structures in amorphous silicon, ge...

We outline recent advances in the fluctuation microscopy technique for probing medium-range structural correlations in disordered materials. The technique was originally developed for electron microscopy, but has now been extended to optical and x-ray microscopies. We show that fluctuation microscopy can detect trace quantities of C60 in a disorder...
