The fourth VOICES (Virtual Ongoing Interdisciplinary Collaborations on Educating with Song) conference will be held Sunday, September 26, 2021 featuring a keynote presentation by acclaimed science communicator Raven “the Science Maven” Baxter (https://scimaven.com) and a bonus presentation by entrepreneur and cognitive psychologist Lana Israel (https://muzology.com). Call for proposals:VOICES explores the use of music to teach STEM content at the secondary or post-secondary level and will include reviewed video posters and interactive sessions of interest to both practitioners and researchers. For full consideration, a presentation proposal should be submitted by July 1 at https://www.CAUSEweb.org/voices/2021/proposals. For inspiration, check out any of the approximately 100 presentations from the three previous VOICES conferences archived for viewing at https://www.CAUSEweb.org/voices/, which have wide-ranging topic areas including research/theory, song parodies, music videos, informal learning and outreach, STEM songwriting, and student songwriting. VOICES especially aims for presentations whose takeaway insights cut across setting and discipline. The use of song or songwriting can be a powerful strategy for learning content for many reasons, such as its community-building appeal to emotion and its capacity to synthesize and present information in concise memorable form (see, for example, https://www.CAUSEweb.org/voices/resources/teaching). These features have become increasingly important in this pandemic age. Please put VOICES 2021 on your calendar and help make our voices heard!
