As an assessment for a recorder playing and comprehension, the third graders created recorder books to be used by the next year’s recorder students. We use the app book creator to write about the recorder and create audio files and videos of recorder songs. The third graders were given guidelines to create ebooks that had title pages, audio recordings, video recordings, and included four to six tips about playing the recorder. Using Book Creator was wonderful for the students as the app is very self-intuitive and the students enjoyed using it immensely. Creating a book allowed the students to display their creativity from writing to performing. For the music educator, this was a wonderful assessment tool so that I could see how much they learned and retained from the unit.
