Teaching First-Grade Students Addition Using Web-Based Interactive Digital Simulations

The dataset used in this study consists of quantitative and qualitative data collected during the implementation of web-based interactive digital simulations for teaching addition to first-grade students. The quantitative data include students’ pre-test and post-test scores, which were used to measure learning outcomes before and after the instructional intervention. The qualitative data comprise teachers’ and students’ responses collected through questionnaires administered after the use of the web-based interactive digital simulations. All data were collected for research purposes and anonymized to protect participants’ identities.
