Pre‐service middle school teachers' specialized content knowledge on sampling variability

Abstract

AbstractThis study investigates a range of non‐normative ideas that pre‐service teachers (PSTs) employ in reasoning about sampling variability. This issue was studied in the context of a content course on statistics and probability for pre‐service middle grade teachers at a Midwestern American university. Analysis of seven PSTs' video and screen records of task‐based interviews has articulated fundamental facets of sampling variability that have not yet been fully explicated in the literature, especially with middle grade PSTs. With the content expectation of sampling variability for middle grade students as suggested by policy reports in the United States of America, this study is particularly fertile ground for designing curricula that can support middle grade PSTs' development of critical specialized content knowledge on sampling variability.
