The Relationship between Problem-Solving Ability (Visual-Spatial) and Handedness Among high school students in Ghorveh city

The purpose of the study was to examine the relationship between problem-solving ability (visual-spatial) and handedness in first-grade male students of the high school in Qorveh. The study was applied in terms of the purpose and correlational with the structural equation modeling (SEM) in terms of method. The population was all male students in the first grade of high school Qorveh in the academic year 2014-2015, who were 830 people, according to the announcement of the education administration of Qorveh. The sample size was determined as 220 people using Cochran's formula. Chapman Handedness Inventory and Kohs block test were used to collect data. For data analysis, SEM was used in SmartPLS. The reliability coefficient of variables, according to Cronbach's alpha, was 0.916 for handedness and 0.665 for problem-solving, showing acceptable reliability. The reliability coefficient of the variables for composite reliability was 0.929 for the handedness and 0.669 for solving the problem, showing acceptable reliability. The average variance extracted for the handedness was 0.611 and 0.475 for problem-solving, showing acceptable validity values. The findings indicated that handedness had no direct effects on students' problem-solving.
