Though numerous studies over the years have produced evidence on which the OTCD standards are based, one quantitative study in 2013 focused specifically on OTCD’s direct impact on
data analysis accuracy (as opposed to merely determining which edtech aspects educators prefer). 211 educators of varied backgrounds at nine schools in six different California school districts participated in the
Over-the-Counter Data’s Impact on Educators’ Data Analysis Accuracy study.
Relating to primary research questions • When a footer was present on education data reports viewed by study participants, educators’ analyses of displayed data were 307% more accurate. When participants specifically
indicated having used the footer (73% of the time), their data analyses were 336% more accurate. • When a reference sheet (following templates) accompanied data reports viewed by study participants, educators’ analyses of displayed data were 205% more accurate. When participants specifically
indicated having used the sheet (50% of the time), their data analyses were 300% more accurate. • When a reference guide (following templates) accompanied data reports viewed by study participants, educators’ analyses of displayed data were 273% more accurate. When participants specifically
indicated having used the guide (52% of the time), their data analyses were 436% more accurate. • Overall, when any OTCD support accompanied data reports viewed by study participants, educators’ analyses of displayed data were 264% more accurate. When participants specifically
indicated having used the support (58% of the time), their data analyses were 355% more accurate. • 87% of the study participants who received no supports indicated they would have used supports – like footers, reference sheets, or reference guides – if the supports had been available. • Participants who received no supports averaged 11% data analysis accuracy (i.e., a score of 11% correct when answering varied data analysis questions such as, according to the viewed data, which area is most likely a site strength, which area is most likely a site weakness, which students did not score
Proficient on the test, and which areas caused students to not score
Proficient on the test).
Relating to Secondary Research Questions • Educators’ school site demographics (secondary independent variables: school level type, school level, academic performance, EL population, Socioeconomically Disadvantaged population, and Students with Disabilities population) had no significant impact on data analysis accuracy or support use. • Educator demographics (secondary independent variables: veteran status, current professional role, perception of own data analysis proficiency, data analysis
professional development time, and number of graduate-level educational measurement courses) had no significant impact on data analysis accuracy or support use. • Minor variations in each support’s framing/format (mainly in terms of length and color usage) had no significant impact on data analysis accuracy or support use. ==Over-the-Counter Data (OTCD) Standards==
