AbstrakPenelitian ini bertujuan untuk mengembangkan instrumen penilaian proyek berbasis model discovery learning yang layak digunakan dan sebagai salah satu inovasi pengembangan penilaian proyek secara lebih oprasional. Penelitian ini merupakan penelitian pengembangan dengan mengintegrasikan model 4-D dengan model pengembangan instrumen nontes. Subjek uji coba yaitu peserta didik Kelas VIII SMP Muhammadiyah 3 Depok, Kabupaten Sleman. Data dalam penelitian ini diperoleh melalui: (1) penilaian berdasarkan masukan para ahli, untuk menentukan validitas isi instrumen; (2) hasil uji coba terbatas untuk menentukan reliabilitas instrumen, instrumen pengumpulan data berupa lembar observasi penilaian proyek untuk mengukur keterampilan pemecahan masalah. Instrumen penilaian proyek berbasis model discovery learning yang dikembangkan dinyatakan valid dan reliabel sehingga layak digunakan serta terbukti dapat digunakan untuk mengukur keterampilan pemecahan masalah peserta didik.

This study aimed at investigating students’ digital literacy skill of students Grade X and XI in Senior High School in Yogyakarta. There were three steps of this research. First, we constructed the item format and aspect of digital literacy skill. Second, the administration of this research to 193 students of science class in Yogyakarta which were selected randomly. The last, analysis data of students’ digital literacy skill based on educational level. For the profile of students’ digital we used descriptive and quantitative statistics (frequency and percent). To determine the significant difference of the students’ level we also used independent sample t-test. Result of this study showed that the students’ digital literacy skill of all students was very low level. In addition, there was significant difference of students’ digital literacy skill based on educational level. The conclusion was students’ digital literacy skill in Yogyakarta was very low and there must an effort to force these skills. Recommendation for the future study is to develop a learning model that can enhance students’ digital literacy skill. For the policy makers, learning based on digital literacy skill must be integrated on the curriculum. ICT learning should be thought to students in Indonesia, especially in Yogyakarta.

This study aims to developing open-ended test for measuring digital literacy skills of students. There are three step of this study, it was defining the construc and formatting objectives, validity by expert review and item administration. The open-ended test was develop based on five components of digital literacy skill: information, communication, content creation, safety, and problem-solving. The open-ended test was initially piloted on four group of samples: interviews and validity by physics expert (2 Professor, 1 Doctoral), professional teachers (N=2), and college students of graduate school (N=2). Modification were made afterwards and the test was administered to a group of science students from high school in Yogyakarta province, Indonesia (N=129). Result of this study are: (1) The open-ended test instrumen proved valid and worthy of use to measure digital literacy skill; (2) Based on expert validation, the teset is valid with CVR value 1.00; (3) the average value and standard deviation of INFIT MNSQ is .83-1.21 (fit with rasch model/good item); (4) The item has a good degree of difficulty with range of difficulty level between (moderate level). The student's digital literacy skill test can also be used to measure student's skill with very low to excellent categories.

Digital literacy skills of students in Indonesia are still very low. This study aims to examining the effectiveness of Online Laboratory Simulation with Concept Mapping and Problem-Based Learning model in improving students’ digital literacy skills. The research objectives have been describing the significances of the difference between learned students using the PBL model, Online Laboratory Simulation with Problem-Based Learning (OLS-PBL) model, Online Laboratory Simulation with Concept Mapping and Problem-Based Learning (OLS-CMPBL) model. It is a quasi-experimental with pre and post-test design. The population of this research is students in Islamic State School Yogyakarta (MAN), Indonesia. The random sampling technique was used from the three schools of Islamic State Schools. There were 97 students of class XI science at Islamic State School 1 (MAN 1) as participant. The technique of data analysis was used the paired-sample t-test, comparative-descriptive analysis, and ANOVA mixed design using SPSS 24. The study reveals: (1) The OLS-CMPBL group has a significant difference in the level of digital literacy skills (sig .0000); (2) the OLS-CMPBL was most effective to improve the skills with gain score 0.207 (low). Learning with the OLS-CMPBL model can be an alternative for policymakers and teachers to solve the problems of digital literacy.
