This study aims to develop and evaluate the validity of
MONORINGAN (Environmental Conservation Monopoly) as a learning
medium for IPAS instruction among fifth-grade elementary school students. The
study employed a Research and Development (R&D) approach based on the
Borg and Gall model, encompassing the stages of research and information
collecting, planning, and developing the preliminary form of the product. Data
were collected through product evaluation questionnaires administered to
subject matter experts and media experts. The validation data were analyzed
using quantitative descriptive analysis techniques. The results indicate that the
developed media achieved a high level of validity, with scores of 93.33% from
subject matter experts and 94.17% from media experts, both categorized as
highly suitable. These findings suggest that the MONORINGAN media is
feasible for use as an instructional tool and has the potential to enhance student
motivation and learning outcomes. In particular, the media promotes more
active and enjoyable learning experiences, thereby facilitating a deeper
understanding of the material. In conclusion, MONORINGAN represents a
valid and promising instructional medium for supporting IPAS learning in
elementary education.
