Marcia Invernizzi is an American professor, author, and researcher in the field of Reading Education.
This tool is designed to measure specific components of literacy (phonological awareness, alphabet knowledge, knowledge of letter sounds, spelling, concept of word, word recognition in isolation, and oral passage reading) to identify struggling readers in order to provide interventions as early as possible.
The Words Their Way series of instructional resources for literacy educators was co-authored by Donald R. Bear, Invernizzi, Shane Templeton, and Francine Johnston.
The books provide screening tools to assess students' skills in various areas of literacy.
It provides lessons teachers can use based on the assessment to specifically address areas of weakness and move students forward in the development.
Book Buddies is a program for providing one-on-one reading interventions for struggling elementary school students.
Inversizzi refers to the National Assessment of Educational Progress (NAEP) report indicating American students are in need of intervention.
