Canonical JSON (keys sorted, no spaces, UTF-8). Its SHA-256 is the hash on chain. The abstract here is gemini shortened, not the author's own text.
{"abstract":"This study investigated the effect of teacher non-instructional tasks on Grade VI learners' Mathematics achievement using a quasi-experimental pretest-posttest design with two intact classes. It compared pretest and posttest performance and learning gains between learners whose teachers performed non-instructional tasks and those whose teachers did not. A researcher-developed Mathematics achievement test was administered. Descriptive statistics summarized performance, while the Wilcoxon signed-rank test examined within-group changes, and the Mann–Whitney U test compared gain scores between groups. Both groups showed significant improvement in Mathematics achievement from pretest to posttest (p < .001). Learners whose teachers performed non-instructional tasks had a mean pretest score of 32.87 and a posttest mean of 41.07, a mean gain of 8.20 points. Learners whose teachers did not perform non-instructional tasks had a mean pretest score of 30.14 and a posttest mean of 36.21, a mean gain of 6.07 points. A statistically significant difference in gain scores was found between the two groups (U = 202.00, p < .001), with the group whose teachers performed non-instructional tasks showing the larger observed gain. The findings did not support the expectation that the absence of non-instructional tasks would result in greater learner gains. Due to the small sample and non-random assignment, these findings should be interpreted cautiously and warrant further investigation.","abstract_source":"gemini_shortened","authors":["Sharon Ranit","Conrado Lombrio"],"date":"2026-10-11","doi":"10.70838/PEMJ.640102","id":11044,"issue":1,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"2a14f9429e7850223995683e556e542e197ec63209bf65b5a6416e4176ec6a22","schema":"scimatic-article/1","title":"Non-Instructional Task of Teachers: Its Effect on Learners’ Performance","volume":64}
