Although I am familiar with Google Docs, I have not yet used them with my students. One of the easiest and most useful ways to incorporate Google Docs with my classroom teaching is to create a form. I could design a form to act as an assessment, in which each student enters in his/her name and responses to various questions. The responses are then represented in a spreadsheet that generates results for the whole class. With 700+ students, this would make data analysis a much more efficient process. Another idea is to have students use Google Docs to collaborate on a report. I could create and share documents with small groups of students, assign each group a topic, e.g. different composers, and monitor their collaboration. This would be especially effective for out-of-classroom use, as we only have 45 minutes per week for Music class. If the students could collaborate on a music report outside of the classroom, we would be better equipped to maximize in-class instructional time. This report could be in the form of a word document or a presentation. I have created and embedded an example below.
