Dataset for "Building Digital Literacy Through Augmented Reality: A Problem-Based Mobile Learning Intervention for Non-Formal Adult Community Learners"

De-identified datasets supporting the associated study. The archive contains four tables for N = 30 non-formal adult community learners: (1) Phase III AR knowledge test (10 binary items, parallel forms: pretest = Form A, posttest = Form B); (2) Phase III self-reported digital-literacy scale (16 items, 5-point confidence, four domains); (3) Phase II website usability/satisfaction (10 items, 5-point Likert); (4) Phase II mobile-application usability/satisfaction (10 items, 5-point Likert). Participant identifiers (P01–P30) are arbitrary codes; no names, demographics, location, or institutional data are included. The data reproduce the reported results: AR knowledge 2.93→6.00 (Cohen's dz = 1.52), digital literacy 2.87→3.52 (dz = 1.18), website M = 4.23, application M = 4.43. A README sheet provides a full data dictionary.
