For the Nth Time, Does Educational Technology Really Make a Difference?—A Large-Scale Investigation of the Effects of Educational TV on Academic Achievement

摘要

This study was part of a larger data gathered in 2014. The study utilized a cross sectional research design to explain whether the exposure of students on educational shows can make a difference in their academic achievement compared to the achievement of students who have no exposureto educational shows. Students’ achievement was measured by a test covering 5 subject areas. The test was administered to 32,768 students of which 13,095 students came from schools that received the Knowledge Channel package for the 2009, 2010, and 2011 grants. The other 19,673 studentswere from comparison schools who had not watched the Knowledge Channel shows. Significant findings revealed that students from recipient schools (RS) have significantly higher scores than those from the comparison schools (CS). Highest effects were noted in English (in 2009 and in 2010) andin Math (in 2011). Students from RS performed better across all subjects compared to students from CS.
