Dataset for Differentiated Gamified Learning in Elementary Multiplication: Effects on Student Engagement and Learning Gains

This dataset accompanies the study entitled "Differentiated Gamified Learning in Elementary Multiplication: Effects on Student Engagement and Learning Gains." The dataset contains anonymized quantitative data collected from fourth-grade elementary school students participating in a differentiated gamified mathematics learning intervention. The dataset includes (1) learning outcomes consisting of pretest scores, posttest scores, and normalized gain (N-Gain), (2) student engagement questionnaire responses, and (3) game mechanics acceptance questionnaire responses. Item-level responses and calculated scores are provided where permitted by institutional research ethics guidelines. All participants provided informed consent, and all personal identifiers were removed prior to repository submission. The dataset was fully anonymized to protect the confidentiality of students, teachers, and the participating school in accordance with institutional research ethics guidelines. This dataset is intended to support research transparency, secondary analysis, and replication studies related to differentiated gamified learning, student engagement, and mathematics education at the elementary school level.
