"A valuable contribution to the field. These materials both respect the complexity of the work and provide a carefully designed and sequenced curriculum for understanding it." -Lew Romagnano, Professor of Mathematical Sciences The Metropolitan State College of Denver "The most usable, unique, and rigorous professional development tools to come along for mathematics. An effective professional development tool to nurture teacher leaders." -April Cherrington, Mathematics Coordinator, San Mateo County Office of Education, CA A new opportunity for mathematics professional development leaders to enhance their ability to support teacher learning! Help leaders learn to lead professional development to achieve specific goals, increase their knowledge of mathematics, and build a repertoire of professional development strategies. Designed expressly for mathematics professional development leaders, this set of case-based leadership materials helps build the facilitation skills, content knowledge, and pedagogy to design and implement effective staff development. Featuring a user's guide, this package also includes two DVDs with 44 seminars arranged into seven modules containing facilitation notes, video clips, participant work, PowerPoint slides, and much more. All seven modules focus on important mathematics and facilitation skills, reflect research on adult learning, and model a community of practice. Unlike a typical guide for a specific professional development program, these materials focus on facilitation issues that are likely to be encountered in a variety of mathematics professional development situations. The multimedia kit demonstrates how leaders can deal with key issues, including: Managing productive mathematical discussions; Working with teacher explanations of mathematical ideas; Being mindful of equity issues in mathematics teaching; Selecting appropriate mathematical tasks; Deepening teachers' knowledge of mathematics; This set of mathematics seminars is the ideal resource for people charged with supporting teacher leaders and others who lead mathematics professional development. Potential users include curriculum leaders, math-science partnerships, university-district partnerships, and mathematics teacher educators.
