Teacher Development Unit Courses are instrument specific. GWSI offers courses in both violin and cello instruction. Each core unit concentrates on one Suzuki book level (Book 1, 2, 3, 4, etc.). The content will follow the syllabus for the instrument being studied and will include performance of the repertory, supervised observation, discussion and completion of assignments as given by the Teacher Trainer. In addition to their focus on Suzuki repertory and instrumental technique, unit courses will also include additional topics as appropriate. These may include review and application of Suzuki philosophy, parent involvement, listening, home practice, private and group lesson formats, learning styles, note-reading and other skills basic to the Suzuki approach.
