A current vision of education in America today is that all students be science literate. To accomplish this, educators and teachers need to be aware of the challenges involved in promoting science literacy: science literacy encompasses a wide range of knowledge, including construction of knowledge, use of that knowledge, and recall of critical facts necessary to apply scientific information in the world today. In addition, teachers and educators need a knowledge of the issues of “inclusion” since students of diverse abilities, including those with disabilities and others at risk for school failure, are being educated, as much as possible, in general education classrooms taught by content experts.

A bridge to span the gap between the challenges of science literacy for all students and the complexities of student diversity is Content Enhancement – instruction that responds to the needs of students of diverse abilities while maintaining content integrity by focusing on the critical information that all students need to know. In Content Enhancement, the teacher helps students learn by organizing information, providing explicit instruction when necessary, and assuring that students are active partners with the teacher and other students in the construction of knowledge. Graphic organizers and instructional sequences have been developed to help teachers organize information at the course, unit and lesson levels; learn to answer large, difficult questions with ideas that can be generalized to other settings; explore and manipulate knowledge by developing analogies and comparisons; and respond to assessments.

For the last decade, policy makers and boards of education have been mandating and searching for school leaders who are knowledgeable about curriculum and instruction or what the reform literature terms instructional leadership. The recognition that expertise in teaching and learning is critical to the achievement in our schools, however, has often been overwhelmed by the management functions of administration and programs in educational administration, which continue to support the role of manager, and provides little, if any, substance for the kinds of knowledge and skills necessary to lead a school instructionally. Recent studies of the instructional leadership contend that the content that has been neglected in the training of administrators is an understanding of subject matter and how an educational leader must transform the theories, ideas, and practices of a subject or discipline into the everyday understandings of classroom teaching. Although the new construct of Leadership Content Knowledge (LDK) provides a new understanding about what leaders need to know about teaching and learning in order to effectively perform the role of instructional leader, the studies of LDK have not yet provided a process for becoming a leader of content knowledge. The author describes a framework for how an educational administrator would become a “Leader of Content Knowledge.”

Learning to teach subject matter topics that emerge as challenging for culturally and linguistically diverse students remains a key goal for prospective teachers. Teacher education needs multiple ways to guide preservice teachers (PSTs) for this work. One context for such teacher development is classroom-based teacher inquiry. I describe an innovation in teacher inquiry pedagogy that mentors PSTs in (a) mining multiple sources of knowledge for teaching challenging areas of content learning, (b) systematically analyzing knowledge gleaned from these sources, and (c) mediating through visual representations the overlapping, reinforcing, and sometimes conflicting ideas gleaned from sources, in order to advance conceptions and practice in content-based learning for diverse youth. I describe the pedagogy in practice, then use a case of one PST to illustrate how her knowledge evolved in learning to teach persuasive writing to early adolescent English language learners. It was in the knowledge sources interface, mediated by visual representations and written reflections, that this PST’s developing knowledge gained texture and depth.

In this chapter, three educators recount experiences of professional development from different perspectives in order to examine the intersection of teacher knowledge and subject matter in the areas of science and mathematics education. Professional development projects are productive avenues for exploring this phenomenon. We share stories of experience from professional develop projects of teachers who were situated in different places on the professional knowledge landscape: one elementary school teacher, one teacher educator, and one mathematics educator. From these various vantage points, the relationship between mathematics and science content knowledge and teacher knowledge holds different complexities and complications. Issues related to balancing teacher knowledge with content knowledge in professional development emerge. Based on the stories of experience and the analysis of the narratives, deliberation of curriculum is seen to be a valuable concept when engaging in professional development with teachers. Further, Pragmatic Intellectual Space is proposed for productive approaches to professional development.

Are education systems converging toward a global model of teacher education or do local models tend to predominate in spite of attempts to reform them? How much do global, national, and local cultures shape and condition future teachers’ opportunities to learn to teach? How do these opportunities influence teachers’ pedagogical content knowledge? In this chapter we use data from the IEA’s first study of the effectiveness of pre-service teacher education in order to investigate teacher education policy, program structure, and outcomes. Using multilevel modeling we found that across countries individual characteristics have a similar and powerful influence on what future teachers come to know at the end of their pre-service programs. The effects of teacher education curriculum on future teachers’ mathematics pedagogical content knowledge reaffirm the prevalence of local cultures on the implementation of an increasingly globalized ideal. We conclude that while the provision of teacher education shares many common features in goals and structure across countries, it is strongly influenced by local conditions and norms, and by cultural notions of the knowledge that is considered essential – framing how quality is to be defined and operationalized – when learning to teach.

Research over the last decade or so has made it clear that quality teachers matter to student achievement. What is less clear is the ways in which they matter and how we can prepare such high-quality teachers. Nowhere is this lack of clarity more evident than in special education, where we have few studies on teacher quality and even fewer studies on the type of preparation opportunities that would lead to high quality. Thus, it is difficult to make evidence-based decisions about how quality special education teachers should be defined and prepared. As a field, we have to turn to research in general education to provide a sense of some of the dimensions of teacher quality and effective teacher education. In this chapter, we provide a summary of the research on characteristics of highly qualified teachers and what we know from the research on teacher education and professional development that might foster these qualities, both in general and in special education. Part of our discussion centers on the concerns surrounding this body of research and the challenges of applying the findings to the field of special education. Although these challenges pose considerable problems, we are optimistic that potential solutions exist and can be reached through an alignment of initial teacher education and induction.
