“…The purpose of this study was to examine how a TPP 1 design, in alignment with several professional organizations’ recommendations and standards publications, 2 influences TCs’ knowledge, skills, and teaching ability readiness as measured by internal measures over sequenced method courses and field experiences with respect to the external high-stakes, standardized edTPA, particularly the secondary mathematics edTPA (Stanford Center for Assessment, Learning and Equity [SCALE], 2020). For context, the structural design of the portfolio incorporates pedagogical constructs (i.e., integrating concepts of planning, instruction, and assessment) and subject-specific pedagogy that aligns with content and pedagogical standards from professional organizations, such as the National Council of Teachers of Mathematics (NCTM; Moldavan, 2018; Pecheone et al, 2016; Tanguay, 2018). TCs must compile artifacts (e.g., lesson plans, student work samples, video segments) that reveal their abilities to plan, instruct, and assess 3–5 consecutive days of mathematics instruction (SCALE, 2020).…”
