Objective: This study aims to review group learning method effect compared to individual learning method on dyslexic students of second grade in elementary school and it evaluates whether their problem will be solved in group and by other`s help? Thus, two methods of learning- Jigsaw I and Jigsaw II methods -were used to review their effects on improving learning and reading of children. Methods: Pretest-posttest design was selected due to semi-experimental method topic. Kessler and mental scale was used to gather data and a test for recognizing reading called Shirazie test was used to determine disorder amount of students reading, also data resulted from pretest, posttest, follow up and delayed tests were used to gather information. Validity coefficient was estimated .87 and reliability coefficient was .96 for total scale, .94 for class scale, and .91 for practical scale during one month that reliability coefficients’ median was reported .75. 30 students were delivered learning services in learning disorders center by one mentor, and in two shifts, preferentially 60 students were under learning services, in this study, 30 students of first shift was selected randomly as experimental group and 30 students of second shift was selected as control group. Gathered information was used for statistical tasks with the use of independent groups` t-test and SPSS software in order to compare performance of two independent groups of experimental and control. Results: Study findings indicate that group learning method effect compared to individual learning method on reducing the problems of dyslexic students of second grade in elementary students of Qazvin city. It is deduced from hypotheses that group learning compared with individual learning is effective in no addition and/or removing words in text, group learning compared with individual learning method is effective in no addition and removing letter or syllable, group learning compared with individual learning method is effective in no substitution of words in text, thus it can be concluded that students that are learned by group method are enjoyed better performance in reading skill.
