Knowing and Learning Mathematics for Teaching


Book Description

There are many questions about the mathematical preparation teachers need. Recent recommendations from a variety of sources state that reforming teacher preparation in postsecondary institutions is central in providing quality mathematics education to all students. The Mathematics Teacher Preparation Content Workshop examined this problem by considering two central questions: What is the mathematical knowledge teachers need to know in order to teach well? How can teachers develop the mathematical knowledge they need to teach well? The Workshop activities focused on using actual acts of teaching such as examining student work, designing tasks, or posing questions, as a medium for teacher learning. The Workshop proceedings, Knowing and Learning Mathematics for Teaching, is a collection of the papers presented, the activities, and plenary sessions that took place.

Between Making and Knowing: Tools in the History of Materials Research


Book Description

This volume offers a comprehensive sketch of the tools used in material research and the rich and diverse stories of how those tools came to be. We aim to give readers a sense of what tools materials researchers required in the late 20th century, and how those tools were developed and became accessible. The volume is in a sense a collective biography of the components of what the philosopher of science, Ian Hacking, calls the "instrumentarium" of materials research. Readers should gain an appreciation of the work materials researchers put into developing and using such tools, and of the tremendous variety of such tools. They should also gain some insight into the material (and hence financial) prerequisites for materials research. Materials research requires funding for the availability and maintenance of its tools; and the category of tools encompasses a broad range of substances, apparatus, institutions, and infrastructure.
