Digitizing Students’ Voices
This chapter focuses on how assessment for learning can be used to promote the development of student understanding of mathematics and mathematical practices as described in the Common Core State Standards for Mathematics while emphasizing the affordances of digital technologies. The mathematical focus centered on the families of functions connected to the mathematical practice of constructing viable arguments when using the digital technology tool, VoiceThread. The chapter describes an iterative model for implementing assessment for learning practices where VoiceThread gave voice to preservice teachers’ mathematical justifications. Findings are taken from a study set in an algebra course designed for preservice elementary teachers working towards a minor in mathematics. Preservice teachers noted the positive impacts of using VoiceThread in improving their justification skills and the benefits of assessment for learning practices on their learning process.
