This is the story of a "journey of discovery" that took place for more than 5 years in a second-grade classroom. The authors' research study revealed how classroom literacy practices affect students' literacy development, and how particular assessment practices can guide students to important reflections about their success as readers and writers. In Journey of Discovery, authors Courtney and Abodeeb advocate for both students and teachers to think constructively about classroom literacy practices through the use of diagnostic-reflective portfolios--the result of a process of collection and reflection in which teachers and students collaborate to demonstrate a learner's growth over time.
