In the United States, Chinese as a world language in the K-12 classroom is an emerging, fast-growing and ever-changing phenomenon. Students of Chinese language are a very diverse population with regard to age, grade levels, needs, language backgrounds and learning styles. Instructional conditions vary in terms of class size, contact hours, intensity of instruction and the availability of equipment and materials, etc. Professional development for teacher preparation and training is inadequate. This book is designed to facilitate true teaching. It aims at reflecting and encouraging a break from traditional practice by combining language materials, teaching references, and instructional design into a single series for easy, quick and solid practical use. This book endeavors to face two essential questions for a teacher of K-12 world language: What do I teach in a K-12 world language classroom? How do I teach in a K-12 would language classroom? Volume II centers on “How” which has two parts: Part I, Teaching Tips – Best Practices, focuses on practical teaching techniques and provides examples of effective experience in grades 6-12 middle and high school Chinese classrooms. It presents instructional strategies in question and answer format and demonstrates some learning activities by categories. And Part II, Thematic Unit Design, provides users with an introduction to the rationales behind the thematic unit designs introduced in this book, a step by step unit design template and directions, a list of suggested units and 10 actual unit designs with possible variations. The book has two editions in traditional and simplified Chinese. This one is the traditional Chinese edition.
