Abstract

The objectives of this study are: (1) To compile a test construction to measure scientific literacy skills of integrated science-based high school MIPA program students by referring to the achievements of scientific literacy according to the 2015 PISA standard, (2) Conduct validation of test items using Rasch modeling. The research design uses ADDIE procedural models (Analysis, Design, Development, Implementation, Evaluation). There are three types of validation in the development of instruments namely content validation, psychometric aspects validation and extract validation with Rasch modeling. The instruments were tested on class XII students of the MIPA Program from Tegal City 2 High School and Tegal City 3 High School involving 112 students. The construction of the test consisted of 17 integrated science cases presented in the form of tests each consisting of three questions referring to scientific literacy competencies according to PISA standard 2015. Test items have fulfilled the validity of the content aspects and psychometric aspects. Extract validation using Rasch modeling gives the following results: (1) The level of item difficulty is in the range of -3 to 3, (2) There are 16 items that are compatible with modeling, (3) There are 97.32% of student responses suitable with modeling, (4) There are 2 items containing DIF. Based on consideration of all aspects of validity, there are 14 items worthy of being used as items for scientific literacy tests.

Abstract

The purpose of this study was to determine the effectiveness of the implementation of Project-based Multi-Representation Discourse model in improving students’ science process skills. The method used was the quasi-experiment with pretest-posttest control group research design. The population in this study was VII graders of SMP N 17 Tegal. The sample was selected using the cluster random sampling techniques. The data were taken through tests, questionnaires, and documentation. The results showed that the students learning using the Project-based Multi-Representation Discourselearning model had an average N-gain percentage of 72.27%. The percentage score was higher than the students studying using the Multi-Representation Discourse (MRD) learning model which had an average N-gain percentage of 42.50%. The results of the data analysis showed that the Project-based Multi-Representation Discourselearning model is effective enough to be applied and has an effect on improving science process skills.
