Abstract

Monotonous learning makes students accustomed to receiving information without searching, evaluating, and processing information independently. This condition has an impact on students' low digital literacy skills. Digital literacy skills are students' abilities to access, understand, evaluate, and use digital information to support the learning process. One effort that can be done is to apply various methods and media in the learning process. A model that can meet these needs is the Reading, Mind Mapping, and Sharing (RMS) learning model. This study aims to examine the effect of implementing the RMS learning model assisted by flipbook media on digital literacy skills in biology subjects of grade XI students of SMAN 11 Samarinda. This study uses a quantitative method using a nonequivalent control group pretest-posttest design with a purposive sampling technique and a sample of 50 students. The instrument analysis technique used is the expert validation test, while the data analysis technique used is the N-Gain test and the independent sample t-test. The N-Gain test of the digital literacy questionnaire in the experimental class was 0.3 with a medium category, while in the control class it was 0.02 with a low category. Furthermore, the results of the independent sample t-test on the digital literacy questionnaire showed a p-value <0.001. Thus, it can be concluded that the flipbook-assisted RMS learning model has an effect on digital literacy skills in biology among eleventh-grade students at SMAN 11 Samarinda. These findings indicate that the flipbook-assisted RMS model is effective in improving students' digital literacy skills through reading activities, concept mapping, and collaborative information sharing.

Abstract

Seventh-grade students of SMP Negeri 37 Samarinda face problems in science learning, namely not achieving learning mastery. The learning process is still dominated by conventional teacher-centered methods that cause students to tend to be passive and learning media are less varied, so that learning activities are not effective. To overcome these problems, this study applies the Problem Based Learning (PBL) learning model assisted by LKPD Liveworksheets which encourages students to think critically and actively to be able to solve problems thoroughly and completely. This study aims to determine the effect of the problem based learning model assisted by LKPD Liveworksheets on the learning outcomes of seventh-grade students in science subjects at SMP Negeri 37 Samarinda. The type of research used is quantitative research with a quasi-experimental method using a non-equivalent control group design. The research sample was selected by purposive sampling consisting of classes VIIC and VIID with a total of 44 students. Data analysis was carried out using the independent sample t test and the N-Gain test. Based on the data analysis, the t-test obtained a significance value of 0.004 (p < 0.05), indicating a significant difference between the learning outcomes of students in the experimental and control classes. Furthermore, the N-Gain analysis showed that the experimental class obtained a score of 0.63, which is in the moderate category, while the control class obtained a score of 0.57, also in the moderate category. These findings indicate that the implementation of the Problem-Based Learning (PBL) model assisted by Student Worksheets (LKPD) based on liveworksheets has a positive impact on improving student learning outcomes in Natural Science (IPA) for seventh graders at SMP Negeri 37 Samarinda.
