Local wisdom in Yogyakarta is very diverse, potential as a learning sources that can be integrated in the science learning process to develop the scientific literacy, which needed in 21st century learning. This research is to produce learning tools based on local wisdom to enhance the students’ scientific literacy. This study used the Plomp’s Model with several phases namely 1) Analysis, 2) Design, 3) Development, 4) Evaluation and 5) Implementation. The instruments used in this research were validation questionnaire of product and instrument for measure of scientific literacy. The result showed that (1) identification local wisdom in Yogyakarta which used in science learning and accordance with topic environmental pollution was utilizing waste batik as a result of the process of making batik in Yogyakarta, (2) learning toolkit based local wisdom have been produced namely lesson plans and students’ worksheet with excellent category of both, and (3) integrating local wisdom in science learning that was develop scientific literacy in very good category. It indicates that learning tools based on local wisdom was effective to use in science learning to develop scientific literacy.

The research aims to (1) produce a student worksheet based on problem based learning that has the potency to improve the 7th grade student's creative thinking skill based on assessment of expert lecturers and science teachers on the content business feasibility component, language and image component, component, and presentation graphics component, (2) know the student response toward the student worksheet based on problem based learning to improve the 7th grade student's creative thinking skills, (3) know the improvement the 7th grade student's creative thinking skills after using the student worksheet based on problem based learning. The design of this research was Research and Development model with 4 d development model which includes define, design, develop, and disseminate. The data analysis technique of appropriateness of the student worksheet and students responses to the student worksheet is quantitative score conversion to qualitative value with five categories, the data analysis technique of the implementation of the problem based learning model and student's creative thinking skill based on observation is a percentage calculation, while the data analysis technique of creative thinking skills pre test and post test is normalized gain score (N-gain score). Based on the results of the research, it can be concluded that (1) a student worksheet based on Problem Based Learning has the potency to improve the 7th grade student's creative thinking skill based on assessment of expert lecturers and science teachers on the content business feasibility component, language and image component, component, and presentation graphics component get score 105.75 of a maximum score of 120 with a value of "A" is categorized as "Very Good", (2) a student worksheet categorized as "Good" with a value of ' B "based on student response with score 66.09 of maximum score of 88, (3) the student's creative thinking skill improves after using a student worksheet based on Problem Based Learning with N-gain score 0.72 categorized as "High".

Since the indigenous knowledge of factual events in the scientific materials is often doubtful, it arises awareness for science investigation through integration of Inquiry Based Learning (IBL) and ethnoscience. This research is to reveal the effectiveness of Inquiry Based Learning (IBL)integrated with ethnoscience to enhance the students’ scientific skills and science literacy. This study used quasi-experimental research with implementation of pretest and posttest. The research samples were 64 students of the first grade junior high school in Yogyakarta. They were divided into two groups, namely experimental group with integration of IBL and ethnoscience and control group with scientific approach. The instruments were observation sheets on scientific skills and science literacy as well as of students’ cognitive test. The scientific skills and scientific literacy data were analyzed using N-Gain, while the testing data were using t-test at the level of significance of 0.05. The result of scientific skills and science literacy enhancement (N-Gain) were 0.73 and 0.69, respectively. On the other hand, the significant number of the given treatment was 0,000and the value was less than 0.05. It indicated that the integration of IBL and ethnoscience was more effective in enhancing the students’ scientific skills and science literacy than the scientific approach.

This study aims at producing an assessment instrument of the PISA model to measure students’ problem-solving skills and scientific literacy in junior high schools that are valid, practical, and having potential effects. This research employed the design of development studies. The analysis used the Item Response Theory (IRT) Rasch model based on the junior high school students' responses to the developed PISA assessment instrument on natural science subjects. The result of this study was a test set of PISA model for the material of Vibration, Wave, and Sound consisting of 40 items. The test was valid in terms of content, constructs, and language according to the expert assessment, and practical based on small group trials. It also had a potential effect based on the students’ answers and questionnaires results in the field test. The qualitative analysis showed that the developed test had several potential effects, i.e. the development of students' problem-solving skills and scientific literacy so that they gained a relatively high ability to solve a test with the PISA model. The results of quantitative analysis through field test trials showed that there was a significant effect from the application of the PISA model test to enhance students’ scientific literacy and problem-solving skills in the junior high school with the Sig. value of 0.000 which was less than the significance level of 0.05 (α = 5%).
