To make progress toward ambitious and equitable goals for students' mathematical development, teachers need opportunities to develop specialized ways of knowing mathematics such as mathematical knowledge for teaching (MKT) for their work with students in the classroom. Professional learning communities (PLCs) are a common model used to support…

This technical report provides information about the sample, survey instrument, and resultant data for the American Instructional Resources Surveys (AIRS) that were administered to principals and teachers in spring 2019 via RAND's American Educator Panels. The AIRS focused on instructional resources used and supported in English language arts,…

A science teacher has the advantage of hooking learners with all their senses: flashes, bangs and smells. The science labs are something that many learners at the start of secondary school (high school) are eager to explore, and when there is an open day at school it feels unfair that the mathematics department has to try to compete for excitement…

Erin has been teaching at Centennial High School for five years. Always an excellent mathematics student, she is nonetheless surprised at the amount of mathematics she has learned since she began teaching. She recently assigned what she thought was a fairly straightforward proportional reasoning task, only to be challenged to understand the…

This study examined the extent to which seventh- and eighth-grade mathematics teachers are aware of National Council of Teachers of Mathematics (NCTM) standards documents, Curriculum and Evaluation Standards for School Mathematics and Principles and Standards for School Mathematics and agree with NCTM's vision of school mathematics as expressed in…

The study documents the extent to which high school teachers reflect on their need to revise and extend their mathematical and practicing knowledge. In this context, teachers worked on a set of tasks as a part of an inquiring community that promoted the use of different computational tools in problem solving approaches. Results indicated that the…

The goal of this research study was to gain an understanding of high school teachers' perceptions of the role of history of mathematics in the classroom as well as their underlying view of mathematics as a discipline. High school teachers from 379 Public High Schools in Massachusetts were contacted and encouraged to take an on-line Likert scale…

While teaching in New York City public schools, the author began planning collaboratively with a team of mathematics teachers. Collaborative planning enabled them to consider a range of issues that may not have emerged had they been planning independently. In this article, the author first describes their work through excerpts of conversations…

For the past decade, students at California State University (CSU) campuses increasingly lack basic mathematics skills. To address this concern, Executive Order No. 665 (1998) called for CSU campuses to bring students to proficiency in mathematics. School districts have struggled to modify their mathematics curriculum, pedagogy, and assessment in…

Investigates the content conceptions of an experienced high school mathematics teacher and links those conceptions to their role in the teacher's first implementation of reform-oriented curricular materials during a six-week unit on functions. Concludes that the teacher's well-articulated ideas about features of a variety of relationships in…

This paper reports on a survey instrument designed to measure opinions regarding computer knowledge and usage among high school teachers of mathematics (N=66) and college faculty of mathematics (N=25). Findings indicate that the college faculty made reference to computer usage more often in their lectures than did the high school teachers.…

Algebra is no longer just for college-bound students. After a widespread push by the National Council of Teachers of Mathematics (NCTM) and teachers across the country, algebra is now a required part of most curricula. However, students' standardized test scores are not at the level they should be. NCTM's seventieth yearbook takes a look at the…

Examines the mathematics competency of teachers of deaf and hard-of-hearing students as a factor in these students' poor performance. Analysis of a survey of teachers of the hearing impaired and administrators indicates insufficient mathematics preparation of teachers, particularly those at the high school level. Suggestions for improving…

Recent research explaining the influence of teacher knowledge and beliefs on instruction tends to illustrate what teachers cannot do by describing their limited beliefs about mathematics or gaps in mathematics knowledge. Those studies illustrating what teachers can do tend to focus on one teacher. This paper describes what nine secondary level…
