N2  - The low quality of mathematics education is a topic that is often discussed, as
evidenced by the large number of studies examining low learning achievement, interest in
learning, and problem-solving skills among students. Similar conditions are observed in
the field, namely low problem-solving abilities and learning interest among students,
influenced by the perception that mathematics is a difficult and uninteresting subject,
difficulties in solving word problems, and learning that still relies heavily on textbooks and
teacher explanations. The development of ethnomathematics-based instructional materials
rooted in Lampung culture using the CPA approach is expected to address these issues.
Research objectives: (1) to describe the product development procedure, (2)
product feasibility, (3) product practicality, and (4) product effectiveness in improving
students' problem-solving skills and interest in learning mathematics. This study adopted
the ADDIE development model with the following stages: analyze, design, development,
implementation, and evaluation. Furthermore, data collection techniques are divided into:
(1) pre-development: observation, interviews, questionnaires, and documentation, (2)
product development: expert validation, practitioner/teacher assessment, and student
response, and (3) testing: tests, questionnaires, and documentation. Data analysis
techniques are also divided into: (1) pre-development: descriptive analysis of preliminary
study results, (2) product development: feasibility and practicality testing, and (3) testing:
paired t-tests and N-Gain tests.
The results of the study indicate that: (1) the product development procedure
begins with needs analysis, creating a design or blueprint, realizing the blueprint into a
product for validation and testing, followed by implementation, and finally evaluation, (2)
the product's feasibility received an average score of 84.09% for subject matter experts,
83% for language experts, 86% for media experts, and 96.8% for cultural experts, all
categorized as highly feasible. (3) The practicality results obtained an average score of
88.6% for practitioners/teachers and 91% for student responses, categorized as highly
practical, and (4) the effectiveness of the product based on the results of the paired t-test
on problem-solving ability and learning interest showed a value of 0.000 < 0.05, indicating
a significant difference between the pre-test and post-test results, while the N-Gain test
results obtained an average score of 0.649 or 64% for problem-solving ability and 0.562
or 56% for learning interest. This indicates that the effectiveness of using teaching
materials in improving problem-solving ability and learning interest falls into the
?moderate? or ?sufficiently effective? category.
