Abstract

Mathematical literacy is very important for the society in the 21st century. An individual is able to see literate not only understands mathematical concepts or materials but can also apply his understanding in solving problems according to the context of the real world. However, mathematical literacy skills at junior high school level are still relatively low, this is obtained from PISA results and initial observations (field). One solution that can be done to overcome the low mathematical literacy is to design a mathematics textbook to support these literacy skills. This research aims to develop junior high school mathematics textbooks that can support mathematical literacy skills. This research is part of a development study that uses a 4-D development model. The 4-D model development stage consists of 4 steps: (1) define, (2) design, (3) develop, and (4) disseminate. This product was validated by 5 experts, namely 2 design experts, 2 material experts, and 1 instrument expert. This Research Instrument consists of a validation sheet of design experts, materials, and instruments (tests of mathematical literacy capabilities). The validator’s suggestions and comments on the mathematics textbook of teaching junior high school were analyzed descriptively, while the data in the form of scores were analyzed descriptively and quantitatively. The results of this study indicate that the design validation of the first and second validators met the valid criteria of 80.53% and 81.58%. The material validation of the first and second validators met the valid criteria, namely 79.31% and 80%. The instrument validation also met the valid criteria of 81.82%. So it can be concluded that the product in the form of junior high school mathematics textbooks meets the valid criteria and is feasible to apply
