Centura Student Learning is Captured in Effect Size Calculations

Centura instructional staff have created formative assessments used by almost every teacher in the district.  After using the mini assessments for over five years, student effect size that is calculated with results indicates that the learning the students are ending the school year with is oftentimes three or four times what is normally expected in a traditional classroom utilizing more traditional assessment measures.

Centura Administrative Staff arrived at this  outcome by comparing the calculated number to John Hattie’s Visible Learning information  https://visible-learning.org/hattie-ranking-influences-effect-sizes-learning-achievement/  where he found the average effect size of all interventions was .40.

For several years Centura has used pre and post-test data from LtoJ® as the third accountability measure. However, earlier this month we were able to add effect size calculations to the data we already had. The advantages of calculating effect sizes are:

  1. The data is for every teacher, not only the half or fewer who must take state assessments. All teachers can be honored by seeing the impact they have had for the year. For example, the high school  health teacher results were calculated to demonstrate an effect size nine times the average influence upon student learning. What this means is that the students actually remembered the content instead of the all too common cram/forget sequence.
  2. The data is easy to average to gain effect sizes for departments, grade levels and whole schools.
  3. The spreadsheet for the calculations is so simple the students can enter the data without compromising any privacy issues.
  4. The results from effect size calculations allow teachers to compare their influence with the average influence from thousands of studies.
  5. This gives school district’s another option for assessment that is at the classroom level.
