Abstract

This study aimed to produce cognitive instruments that could help teachers train students' literacy skills. The development of cognitive instruments based on scientific literacy on sound material was aimed at; (1) Describe the validity of the instrument being developed, (2) Describe the reliability of the instrument being developed, (3) Describe the level of difficulty of the instrument being developed, and (4) Describe the distinguishing power of the instrument being developed. This research was a research and development with research design using the development of Research and Development (R & D) adaptation of Borg and Gall (1983), namely potential and problems, data collection, product design, design validation, product testing, product revision, usage testing, and final product revisions. The resulting product was a cognitive instrument based on scientific literacy in the form of a description test with a level of C2 to C4 of 10 questions. The products were tested in Banjarmasin State Junior High School 4, Banjarmasin State Middle School 15, and Banjarmasin State Middle School 24. The data analysis technique uses item response theory, the Rasch model. The results showed: (1) the validity of the instrument developed was valid, (2) the reliability of the instrument developed was excellent with alpha Cronbach 0.86, (3) the difficulty level of the instrument developed was very difficult 20%, difficult 30%, easy 30% and very easy 20%, and (4) the differentiating power of the instruments developed was 80% good and 20% bad. The conclusion of cognitive literacy-based science instrument with good category was obtained so that it is feasible to use.
