TY - JOUR TI - Investigation of the Effect of Online (Web-Based) Formative Assessment Applications on Students' Academic Achievement AB - The purpose of this research is to examine the effects of providing resources for learning disabilities by the system and providing feedback regarding learning disabilities by the teacher within the scope of an online (web- based) formative evaluation application for 10th grade secondary school students in mathematics course quadratic equations on students' success. In the research, a quasi-experimental design was used. Pre-test - post- test achievement tests and follow-up tests were used. The research was conducted in the 2022-2023 academic year with a total of 302 students selected from 4 schools and 12 branches in Göksun and Andırın districts using the stratified, random cluster sampling method. Data were examined by one-way analysis of variance (ANOVA) and analysis of covariance (ANCOVA). According to the research results, it was determined that there was no statistically significant difference between the pre-test averages of the groups, but a statistically significant difference emerged in the post-test. Providing resources for learning disabilities by the system applied to the Experiment-2 group and Cognitive Diagnostic Modeling (CDM) for learning disabilities by the teacher. Providing detailed feedback according to the system, providing resources for learning disabilities by the system applied to the Experiment-1 group, and normal teaching applied to the Control group; It was determined that the system applied to the Experiment-1 group provided resources for learning disabilities and was more effective than the normal teaching applied to the control group. In addition, according to the results of the experimental process, Experiment-2 showed a higher level of improvement than Experiment-1 and Experiment-1 between the pre-post test averages of the Control group.
