Abstract

In this study, it was aimed to develop an analytical rubric that measures performance levels for Science/Chemistry Laboratory Applications and to examine its reliability with generalizability theory. The study group consists of 18 grade 5-6 secondary school students in formal education, taking science or chemistry laboratory courses in a science and art center in the 2020-2021 academic year. In addition, the laboratory performances of students were scored simultaneously by three expert raters, using an analytical rubric. In addition, during the development process of the rubric, opinions of eight experts were obtained when determining and arranging performance indicators and performance levels. It was determined that the scale developed with the findings obtained as a result of the performance scale development study yielded valid, reliable, and generalizable results in determining the performance of students who attended to science / chemistry laboratory practices. In this context, it is thought that the use of this scale, which was developed to evaluate the performance of students in secondary school science/chemistry laboratory practice courses, will provide valid and reliable measurement results and will make the evaluation process more objective.
