All the work produced by the participants during the semester was gathered and analyzed, and further augmented with informal conversations, semi-structured interviews, and on-site observations. The participants were followed throughout 14 weeks, both in a graduate course on Literacy and in their internship placements, and while they planned and instructed students within the context of a literacy unit. This investigation is based upon three case-studies, and follows three pre-service teachers in their first semester of the internship year. Thus, Preservice teachers that are prepared in programs that are steeped within narrow notions of Multicultural Education, conceptualizations of professionalization based on expertise areas, and induction practices guided by silent binaries, might have restricted perceptions of children, and ii have difficulty identifying IRVs that fall outside of the purview of their pre-conceived professional lens and, in turn, have restricted ways of seeing and doing which result into unresolved tensions when attempting to plan and instruct ALL students.

This study is based on the premise that Three Problems of Practice promote particular ways of seeing and doing which compel teachers to see narrow categories of children. IRV stands for, not only those qualities that are innate or long-term, but also circumstances that may be punctual, or of short-duration (including the child’s relationship with their teacher), and that either provide affordances or prevent learning from occurring if a teacher- lead action does not take place. IRV is used to represent competencies and circumstances that impact teaching and learning, while allowing for overlap and gradation.

Instructionally Relevant Variation (IRV) is conceptually related to notions of pedagogy, characteristics of students and the mediating spaces between students and teachers, and indicates a set of qualities, or markers, that is fluid and all encompassing.

This dissertation thesis describes a research inquiry that took place at a large Midwestern University, in the Fall semester of 2009, is comprised of three case studies, and attempts to respond to the question: “How do prospective teachers perceive, think about, and respond to the instructionally relevant variation of their students”.
