DEVELOPING MATH SKILLS IN TEACHEAR STUDENTS BY KHAN ACADEMY

Abstract

The purpose of this research is to determine the academic achievement arising from the Khan Academy ́s Elementary Mathematics course perfomence. The research design was pre-experimental, with pre-observation and post-observation practices. The sample was census, formed by 70 normal school students. Mathematical academic school grades were comparedbefore and after the mediation; as well as the student self-assessment achieved by a reliable question guide (Cronbach's alpha = 0.809). The results show that the course contributes significantly to the increment ofstudents mathema cal skills:school grades raised from X = 7.68 to X = 8.63 (t = -9.03, df = 69, valor crítico de t dos colas= 1.99 p=2.28-13) and self- assesment from X = 7.75 to X 8.75 (t = -9.06, df = 69, valor crítico de t dos colas= 1.99 p=2.65-13). The students got 83.69 (+9.28) basic math skills, they considered that the course assist to increases their peformence in a 4.11 (+0.83), on Likert ́s scale; becasues it enables to remember basic knowledge.
