摘要: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.
