Correlation of the student’s group and individual performance in a diffraction experiment

Abstract

Group dynamics has a strong influence on group members. This dynamics can merge in a cooperative learning group. In this study, we focus on the factors in group dynamics that can be linked to the increase and decrease of an individual’s performance in a laboratory experiment. The general increase in the item response pattern (IRP) of the upper and the lower 27% can be accounted to the group dynamics’ rate of productivity. Based on the Hake factor, the improvement in the individual performances of the upper 27% is greater than that of the lower 27%. Interaction, interdependence, structure, cohesiveness and goals are factors that link group dynamics and the individual performance.
