This study deals with determining the impact of the performance tasks in the social studies course assigned to the 4th grade students about helpfulness and solidarity on their attitudes and level of acquisition of helpfulness value among students. "Mixed method", which is formed as a result of using a combination of qualitative and quantitative research designs was employed during the study. The experimental and control groups consisted of 16 students in each group. The research data were obtained based on the student reports, Helpfulness Attitude Scale and the Form of Your Feelings. Descriptive analysis method was employed in the qualitative data analysis, while Mann-Whitney U Test was used in the analysis of quantitative data. The result of the analysis suggested that there was a significant difference in favor of the experimental group (U = 24.000, p less than 0.05). Moreover, the result of the qualitative data analysis showed that experimental group students displayed positive attitudes and they seemed happy to help each other. In addition, they were observed to consider assistance important and they seemed willing to continue helping each other after the task. These results suggested that the performance tasks assigned to improve assistance and helpfulness proved effective to help students develop positive attitudes and behaviors.
