Educational Testing and Validity of Conclusions in the Scholarship of Teaching and Learning

Abstract: Validity and its integral evidence of reliability are fundamentals for educational and psychological measurement, and standards of educational testing. Herein, we describe these standards of educational testing, along with their subtypes including internal consistency, inter-rater reliability, and inter-rater agreement. Next, related issues of measurement error and effect size are discussed. This article concludes with a call for future authors to improve reporting of psychometrics and practical significance w… Show more

“…Although the goal response rate of 70% was not met in all subsets of our sample, the distribution of respondents in each category of our sample was similar to the population (Table 1 and Table 2), which is 1 method of testing validity, 20,21 so our results should apply to all colleges and schools of pharmacy. Verification was not completed to ensure that only 1 survey instrument per institution was received.…”

“…We were able to minimize or control for certain variables such as student demographics and lack of content changes, and use identical assessment measures with internal consistency reliability scores (KR-20.0.7) deemed sufficient for classroom examinations. 25 Therefore, making the switch to the POGIL strategy was the only major difference between the comparison groups.…”

The Kuder-Richardson formula 20 (KR-20), a measure of internal consistency reliability, 25 was calculated for each examination using DataLink Connect software, version 4.2 (Apperson Education Products, Renton, WA).…”
