A Consideration Of Tracking Within A Bounded Educational System, Scott David Ripley

Walden Dissertations and Doctoral Studies

American education is built upon a cultural paradigm of equality and access. Tracking students into homogenous classes based on prior academic performance could disadvantage lower-achieving students, thereby reinforcing inequality. The problem in the study district is that homogenous tracking was implemented, yet the system had not been evaluated within the context of implementation. The purpose of this qualitative case study was to examine educators' perceptions of the practice of tracking. Bandura and Maslow's social cognitive theory provided the conceptual framework and Dewey's beliefs on social justice and a spirit of equity provided the theoretical foundation. Open-ended narrative questionnaires were disseminated …
