The development of mathematics e-modules to support learning has
been widely conducted; however, e-modules designed with ICARE
components on the topic of triangles remain limited. This study aims
to develop mathematics teaching materials in the form of an ICAREbased e-module for the topic of triangles for eighth-grade students.
The research type used is development or Research and
Development (R&D) employing the ADDIE development model.
However, the implementation was limited to three stages: Analysis,
Design, and Development. The subjects of this study were two
mathematics teachers. The e-module was validated by content
experts and design experts. Instruments used to collect data included
interviews, validation questionnaires, and educator response
questionnaires. The analysis stage results indicate that students
require alternative digital teaching materials to support learning. In
the design stage, an ICARE-approach mathematics e-module on
triangles was developed to facilitate student understanding. The
development stage included validation tests by content and design
experts, yielding highly valid results. The e-module’s content
validity reached 91.35%, categorized as very valid, while its design
validity reached 87.21%, also categorized as very valid.
Additionally, a practicality test by educators yielded a result of
66.80%, categorized as sufficiently practical. Thus, this e-module is
expected to serve as an alternative digital teaching material that
effectively supports the mathematics learning process and acts as a
self-learning medium for students, thereby increasing student
motivation. It is also expected that future research will consider this
e-module as an additional learning resource for teachers that can
support differentiated instruction.
