FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -How is effect size calculated? Effect size is calculated by taking the difference in two mean scores and then dividing this figure by the average spread of student scores (i.e. average standard deviation*). To be valid, the spread of scores should be approximately distributed in a ‘normal’ bell curve shape.

Detailed explanation-2: -Few would argue the importance of feedback to increase student achievement even without having read the research from John Hattie. With an effect size of . 73, Feedback is almost double that of the hinge point . 4, making it an effective instructional strategy that is applicable across disciplines and grades.

Detailed explanation-3: -The Origins of Jigsaw For example, John Hattie’s recent update to his list of influences on student learning indicates that the jigsaw approach has an effect size of 1.20.

Detailed explanation-4: -(For example, an effect size of 0.7 means that the score of the average student in the intervention group is 0.7 standard deviations higher than the average student in the “control group, ” and hence exceeds the scores of 69% of the similar group of students that did not receive the intervention.)
