Development of Three-Tier Test Instrument Based on Scientific Literacy in Electrolyte and Non-Electrolyte Solution Topics

Abstract

The scientific literacy is very important for students as a provision to face the challenges of the 21st century. The scientific literacy of students in Indonesia is low. One of the factors which causes students' scientific literacy tend to be low is that students have not been trained in answering questions with typical as on PISA. Efforts to train students to be familiar with scientific literacy include developing test instruments based on scientific literacy. This study aims to examine the feasibility and characteristics of the scientific literacy test instrument for electrolyte and non-electrolyte solutions; besides, examine the profile of students' scientific literacy abilities. The type of this study was Research & Development with a 4D model which includes the stages: define, design, develop, and disseminate. The research subjects were students of class X Science SMAN 1 Sragen. The results of the study show that (1) the scientific literacy test instrument which is developed is feasible and valid to be used with a validity of 34 of 35 questions which is declared valid and reliability of 0.86; (2) the characteristics of the test instrument is that using three aspects of scientific literacy in one question at once and can be used to determine the student's scientific literacy profile well; (3) the profile of students' scientific literacy skills is in a fairly good criterion with a percentage of 59%. The profile of students' scientific literacy abilities from the aspect of scientific competence is obtained as much as 57.21%; 59.72%; and 60.46%.
