The effectiveness of using e-modules in atomic structure material to improve scientific literacy ability of students
The purpose of this study is to determine the effectiveness of using e-modules to improve scientific literacy skills of students. This e-module is designed on atomic structure material. The used method is pre-experimental using one group pretest-posttest only design. Research instrument was involved in a scientific literacy ability test consisting of 10 description questions. Sampling technique was used purposive sampling. Data analysis technique was tested using a paired sample t-test and N-Gain value. From the sample testing, it was obtained a significance value of p<0.05 (p=0.000). This data showed that there was a significant difference between the scientific literacy abilities of students before and after using e-modules. The average value of N-Gain was found that the increase in students' scientific literacy skills was 0.74 with high category. This value is detailed as 0.87 (high) for the context aspect, 0.75 (high) for the knowledge aspect, 0.69 (medium) for the competency aspect and 0.73 (high) for the attitude aspect. Based on the data, it can be concluded that the use of e-modules on the atomic structure material was found to be effective in improving students' scientific literacy skills.
