The relationship between the circadian rhythms and academic performance of female students in sixth grade of school

Everything in the world has a slow motion. Taking a look around, we find that life, in the form of periodic activity is orderly fashion. The purpose of this paper was to examine the relationship between circadian rhythms of the students and their academic performance.The research methods were correlation. The study population was formed of sixth grade school female students of Tehran 12th region using stratified random sampling method was adopted 70 persons.To assess the circadian rhythm of students of morning and evening time, Horne and ostberg questionnaire (1976) was used. Student’s academic performance was measured through toulouse pieron attention test, math test, a test of visual memory (visual) and verbal memory test (oral). To compare the circadian rhythms of students (morning and evening time) T-test is used and to compare the relationship between circadian rhythm and shifts in student’s assessment analysis of variance (ANOVA) was used. The results showed that there is a relationship between the type of circadian cycle and academic performance including verbal memory, mathematical performance and accuracy. But there was no significant(meaningful) relationship with visual memory. Also, there was a significant difference between the academic performance of students in the morning and evening time. Therefore, in order to optimize the processes of learning and teaching and useful planning, it is necessary directors and training officers be informed of high and low efficiency hours of students.
