Summarizing Trend in Student Achievement: A Comparison of Methods

Shinn, Mark R., Good, Roland H., Stein, Stephanie·1989·School Psychology Review

Abstract

A substantial literature is evolving in support of direct, continuous monitoring of student academic achievement with data-based modifications of instruction. A critical element in proposed data-utilization strategies is an estimation of the slope of student skill acquisition. The split-middle (SM) and ordinary-least-squares (OLS) procedures have been recommended for this purpose, but little is known regarding their relative advantages. This study examined the accuracy and precision of the SM and OLS estimates of trend for 20 special education students whose reading progress was monitored for an academic year using Curriculum-Based Measurement (CBM) procedures. Although neither procedure resulted in systematic over-or under-predictions of performance, the OLS procedure generated estimates of future performance that were consistently closer to actual performance than the SM estimates. Thus, practitioners estimating the trend of CBM measures of reading skill can expect an increase in the precision of the estimates if they use an OLS estimate instead of the SM estimate.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
