Instrument Development in Measuring the Scientific Literacy Integrated Character Level of Junior High School Students

The objectives of this study were to develop the scale called the student test of scientific literacy integrated character (SToSLiC), to analyze its validity and reliability, and to portray the primary profile of scientific literacy integrated character of junior high school students in Mataram. The scale was developed in four steps include identifying indicators, developing pool items, checking items validity and reliability, and improving items quality. The scale consists of two parts that are the SToSLiC-A and the SToSLiC-B. The primary pool items of the SToSLiC-A consist of 42 multiple choice items, and 40 Likert-scale items for the SToSLiC-B. The scale was administered to 222 eight graders student in Mataram city. Seven items were eliminated from the initial SToSLiC-A because of the item total correlation were < 0.05 or invalid. Based on item total correlation of the 35 remaining items, the SToSLiC-A was classified as valid (item total correlation coefficient > 0.05), and it has good internal consistency (Alpha-Cronbach coefficient of 0,63). All 40 items of the SToSLiC-B were valid (item total correlations > 0.05) with good internal consistency (Alpha-Cronbach coefficient of 0.87). Based on these values, it can be concluded that the SToSLiC developed in this study provide an objective measure of acquisition of scientific literacy and character of junior high school students.
