Abstract
Facing the challenges of the 21st century, it is essential for students to have basic knowledge of science. The ability of scientific literacy relates to how students conceive the environment, health, economy, and problems of modern society which are more concerned to technology, advancement, and science development. Therefore, it is necessary to develop a scientific literacy test instrument that intends to measure students' scientific literacy skills. The objectives of this study were (1) to examine the feasibility of online scientific literacy test instrument in acid-base material, (2) analyze the level of validity and reliability of online scientific literacy test instrument in acid-based material, and (3) examine the profile of students' scientific literacy skills toward the test instrument. This Research and Development (R&D) 4D model which adapted by Thiagarajan (1974) shows the feasibility and validity of the scientific literacy test instrument with score 0.414 and 0.782, respectively. The profile of students' scientific literacy skills was in good criteria of 67%. The profiles of students' scientific literacy skills of competence aspects were 66%, 63%, and 72%, respectively.
Highlights
The rapid development of science and technology in the 21st century requires students not to continue to think conventionally (Rahayu, 2019)
Indonesian students' low scientific literacy skills are caused by various factors, including education, which is still oriented to tests and exams (Gherardini, 2016)
In the observation stage, which was supported by preliminary interviews, it was known that many teachers did not understand scientific literacy, and the assessment instruments used still did not fulfill the aspects of scientific literacy
Summary
The rapid development of science and technology in the 21st century requires students not to continue to think conventionally (Rahayu, 2019). Another challenge in facing the 21st century is the importance of students having a foundation in science (Suma et al, 2018). The scientific literacy ability of Indonesian students based on PISA and TIMMS shows that they are still in the lower stage. Indonesian students' low scientific literacy skills are caused by various factors, including education, which is still oriented to tests and exams (Gherardini, 2016). Based on the Republic of Indonesia, Joko Widodo, education in Indonesia is expected to increase, especially in literacy, mathematics, and science skills. No more Indonesian students would be left behind (Widodo, 2020)
