Over the last 50 years, the International Association for the Evaluation of Educational Achievement (IEA) has conducted more than 23 large-scale comparative studies of student achievement. The work associated with teacher preparation as well as experience gained in many of IEA's studies, such as TIMSS, led to a request from members of the…

In this journal issue, the authors of the focus articles have provided a suite of very stimulating and thoughtful articles. The overarching purpose of this research is to explore the application of principles derived from the view of validity proposed by Kane (2004) to their research on issues related to the measurement of mathematical knowledge…

The authors of this volume's stimulus papers have taken on the challenge of developing measures of teachers' mathematical knowledge for teaching (MKT). This task involves multiple decisions and considerations, including: (1) How does one specify the body of knowledge being assessed? What warrants are offered for those choices?; (2) How does one…

In this paper are discussed recent efforts to provide preservice mathematics teachers with opportunities to connect elementary teaching methods and content with the content and methods of secondary school mathematics. Through an in-depth exploration of the game, Shut the Box, preservice elementary and secondary mathematics teachers thoughtfully…

This article suggests some reasons why an urban education project in Australia might inform current debates surrounding teacher education. The first section provides a brief overview of the Australian education system from 1950--1980 as a way of introducing the larger historical context in which teacher education is situated. The second part…

Pedagogical patterns have been around since 1995, but several authors claim their impact is limited. However, these claims are based on authors' own observations and not on methodical evaluations of the use and dissemination of pedagogical patterns. This claim is in contrast to the vision of the creators of pedagogical patterns--they think…

Career and technical educators have long recognized the fact that a highly skilled craftsperson is not necessarily a highly skilled instructor of that craft. In the belief that the key to a productive, efficient workforce lies in high quality training for journeymen and apprentices, the Carpenter's International Training Fund (CITF) partnered with…

Biotechnology is an expanding area of scientific and community interest, one that it is important students understand because of its potential to impact on them and their communities. The issue for teachers and science and technology educators is how to provide learning experiences in this area. This paper draws on classroom-based research to…

Broad support exists within the science education community for the incorporation of socioscientific issues (SSI) and argumentation in the science curriculum. This study investigates how content knowledge and morality contribute to the quality of SSI argumentation among high school students. We employed a mixed-methods approach: 56 participants…

Pedagogical content knowledge, the content-specific knowledge which embodies the aspects of content most germane to its teachability and which is most likely to distinguish the understanding of the content specialist from the pedagogue, has been widely regarded as important for effective teaching of complex subject matter such as science. This…

The purpose of this paper is to present a brief overview of the nature of pedagogical content knowledge and to offer a list of working hypotheses concerning it for incorporation into teacher education programs. What teachers know about teaching, such as preinstructional strategies, the use of concrete examples and manipulatives, formative testing,…

A study investigated whether a course in pedagogical content in English would have an impact on the lesson plans of 11 student teachers. Students were directed to write lesson plans for the short story "To Build a Fire" by Jack London, both at the beginning of the course and at the conclusion. Student teachers' perceptions of their…

This exploratory study examined the structure of declarative knowledge about pedagogy housed in the memory of an experienced teacher educator, and it sought to determine the teacher educator's influence on the development of declarative knowledge structures in undergraduate students enrolled in three sections of a physical education teaching…

The 1993 National Survey of Science and Mathematics Education, which involved approximately 6,000 teachers in grades 1-12, was designed to provide up-to-date information and to identify trends in the areas of teacher background and experience, curriculum and instruction, and the availability and use of instructional resources. Some questions…

This study examined what teachers needed to learn to teach in new ways and how teachers developed those capacities. It also investigated the additional skills and orientations teachers needed to take on leadership roles and how teacher leaders acquired their ability to lead their colleagues. Data came from a 2-year study of 10 exemplary teacher…
