Article
The concept of teacher noticing has been a powerful methodological tool for understanding teachers’ decision-making and professional judgment. In this line of inquiry, researchers usually try to identify elements of classroom practice salient to teachers. Data about teacher noticing and decision making can be collected at scale through the use of s...
Article
This study analyses College of Education and Human Development an online scenario-based instrument in which secondary mathematics teachers from across the United States were presented with episodes of mathematics instruction and then asked to make a decision at a critical juncture. The theory of practical rationality suggests that the decisions of...

This study employs a cross-case analysis to explore the demands and opportunities that arise when information problem-solving tasks are introduced into college mathematics classes. Mathematics teachers at three universities developed and introduced tasks that required students to seek out, evaluate, and synthesize quantitative claims from disparate...
Conference Paper
Using mixed-effects regression, we analyzed teachers’ responses to a multimedia survey of instructional practices in posing proof problems in geometry. Teachers described and rated for appropriateness three different ways of involving students in deciding what to prove, including one in which the teacher chooses the givens and the conclusion to pro...
Conference Paper
Based on data collected from the administration of a multimedia questionnaire to a nationally-distributed sample of secondary mathematics teachers, we investigated such teachers’ stances on the norm of high school geometry instruction that the teacher is responsible for providing the propositions (‘given’ and ‘prove’ statements) that students are a...
Conference Paper
Full-text available
A challenge inherent in improving mathematics instruction is whether new practices will be adopted and sustained by practitioners. In order to better understand the circumstances under which mathematics teachers are willing to depart from customary instruction, we report on findings from a study in which K-12 mathematics teachers were asked to eval...
Conference Paper
Secondary geometry teachers have been shown to recognize norms of instructional situations such as installing a new theorem (Herbst, Nachlieli, & Chazan, 2011) or doing proofs (Herbst, Aaron, Dimmel, & Erickson, 2013). In the latter case, the diagrammatic register norm describes the customary way in which a diagram and notation are used to present...
Article
This study presents an analysis of whether geometry teachers create opportunities for student discussion when engaging students in proving as revealed through the use of a multimedia survey instrument. We presented 42 secondary mathematics teachers with 8 multimedia narratives set in the situation of doing proofs in high school geometry and asked t...

Does a citizen need to possess quantitative literacy in order to make responsible decisions on behalf of the public good? If so, how much is enough? This paper presents an analysis of the quantitative claims made on behalf of ballot measures in order to better delineate the role of quantitative literacy for the citizen. I argue that this role is su...
Conference Paper

Records of what takes place in mathematics classrooms are indispensable in mathematics teacher education and in research on mathematics teaching. We describe here the LessonSketch environment, an online platform for creating and analyzing representations of mathematics classrooms. We describe the authoring and analytic tools of LessonSketch with a...
Conference Paper
Full-text available
We discuss findings from a study of 226 K-12 mathematics teachers who rated the appropriateness of instructional actions in a scenario-based assessment. The teaching actions shown in the scenarios were designed to represent mathematics teachers fulfilling their obligation to the discipline of mathematics. Our analysis of the participants' follow-up...
Article
Full-text available
This paper describes instruments designed to use multimedia to study at scale the instructional decisions that mathematics teachers make as well as teachers’ recognition of elements of the context of their work that might influence those decision. This methodological contribution shows how evidence of constructs like instructional norm and professi...

Article
Full-text available
Rational dependence is the reasoned dependence on the expertise of others. This dissertation begins with the argument that if mathematics instruction is to help prepare students for the quantitative claims that they may expect to encounter in their everyday lives, then they need to be given the opportunity to develop rational dependence. In order t...
Article
We compared effects of video and animated representations of teaching practice among teacher candidates. Sixty-one participants completed a questionnaire rating the representation in terms of its genuineness and its effectiveness enabling users to project to it their own experiences, to reflect, to conceive of alternative actions, and to notice asp...
Article
Using a multimedia questionnaire we explore the extent to which secondary mathematics teachers recognize a hypothesized norm of doing proofs in geometry???that the teacher is in charge of providing the 'given' and the 'prove.' We also explore whether teachers who recognize the norm make a negative appraisal of its breach and find that geometry teac...
