A(n)__________ is a reflective practice tool that allows teachers to reflect on philosophy, environment, beliefs, and identity.

A portfolio serves as a reflective practice tool that enables teachers to evaluate their philosophy, environment, beliefs, and identity. It is a comprehensive collection of artifacts that showcases a teacher's experiences, skills, and professional growth over time. By compiling lesson plans, assessments, student work, and personal reflections, educators can gain insights into their teaching practice and how it aligns with their core beliefs and values. This process of reflection helps teachers identify areas for improvement and encourages professional development.

In contrast, a checklist primarily functions as a quick way to ensure that certain tasks or criteria have been met, without the depth of reflection offered by a portfolio. Incident analysis focuses on dissecting specific events or occurrences in the classroom to understand what transpired and why, typically addressing specific incidents rather than an overarching view of one’s practice. Peer observation involves observing a colleague's teaching to provide feedback and share best practices but relies on an external perspective rather than the individual's reflective insights found in a portfolio.
