This development research was aimed to produce
mathematics comics media which valid and practical. This research
was a research and development employing the 4-D model by
Thiagarajan & Semmel (1974). The model consisted of four
development stages, namely define, design, develop and disseminate.
The research instruments were validation sheets and practicality sheets.
The data were analyzed by grouping the data based on the product
qualification. The calculations were made to obtain mean scores
classified into categories in the Likert scale assessment. The validity of
product can be seen from the result of experts validation which show
that the product was valid (86.25%). The practicality of product can be
seen from the result of the teacher and students practicality assessment
sheet which show that the product was in a practical category (90.04%).
Thus, it can be concluded that the mathematics comics media on
linear equations and linear inequalities of one variable was valid and
very practical to be used as a medium of learning in mathematics.
