A Tool for Assessing Individual Student Contribution in Performing STEM-based Group Tasks

STEM-based education, in parallel with its indisputable merits, poses a number of challenges to pedagogical specialists. One of them is related to the individual evaluation of students when performing group tasks. The article presents a diagnostic tool, through which, in an objective way, the individual contribution of each of the students who worked on a given group task can be established. This allows the assessment of the final group product to be transferred proportionally to each student according to their contribution. The presented tool was developed on the basis of Jacob Moreno‘s sociometrics and it is based on a rotating group assessment that students perform on their own. Thus, both the teacher and the students participate in the formation of the final individual assessment. The tool is intended for students in grades 8-12. The presented version of the tool is a prototype. Data on its construct and content validity were obtained through expert evaluation.
