This study was to determine the effect of the use of internet-based learning media in improving the scientific literacy skills of PGSD students. The method used in this study was pre-experimental with the research design of one group pretest-posttest. The population in this study were all IKIP Siliwangi PGSD students in the fourth semester of regular classes and non-regular classes with a total of 300 students. The sample in the study was regular class students with 38 students. The instruments used included tests, validation sheets and observation sheets. Research results show that the sig value. (2-tailed) 0,000 <0,05, it can be concluded that H0 is rejected and H1 is accepted. Thus there is a difference in the average scientific literacy ability between pretest and posttest and it can be concluded that the use of internet-based learning media can improve students' scientific literacy skills. Student observation data shows that learning using internet-based learning media can increase student activity with the percentage of 53.75% of active students and 46.25% of fasive students in learning.

This research is motivated by a change in learning methods that were initially face-to-face to online learning that resulted from the COVOD-19 outbreak. The purpose of this study was to analyze the mathematical resilience of elementary school students during learning during the COVOD-19 pandemic. The method used in this research is descriptive method with 36 elementary school students as subjects in one of the primary schools in Majalengka district, West Java, Indonesia. The results of this study, mathematics resilience of elementary school students is in the medium category. The findings related to mathematics resilience of elementary school students namely resilience is not only influenced by the complexity of the material and changes in learning methods. However other factors such as the packaging of learning by the teacher, the media used by the teacher, and the communication used by the teacher also affect the mathematics resilience of elementary school students.

This study aims to determine the effect of the learning media and the ability to think creative of to the ability to science literacy student of elementary school. The study was conducted at the grade V SDN Manangga and SDN Tenjonagara Kabupaten Sumedang. Research design using experiment method with treatment by level 2 x 2. Data analysis is the two way anava. The results of this study indicate that (1) There were differences in the ability to science literacy of student of study by using ICT media with education aids. (2) There was an interactional of the learning media and the ability to think creative of the ability to science literacy student of elementary school. (3) The ability to science literacy student who have high the ability to high think creative by using ICT media  more high compare who have the ability to high think creative by using education aids.(4) The ability to science literacy student who have low the ability to low think creative by using ICT media  more low compare who have the ability to low think creative by using education aids

This study aims to determine the effect of the STEM approach on mathematics literacy abilities of elementary school teacher education students. The method used in this research is pre-experimental with One-Group Pretest-Posttest Design with a population of semester 2 PGSD students with a total of 188 students. The sample in this study was 50 students. The instruments used include: mathematics literacy ability tests, interviews, and observation instruments. The results showed that: 1) there was an effect of the STEM approach on the mathematics literacy ability of elementary school teacher education students; 2) to further optimize learning it must be prepared more thoroughly and planned, 3) the role of educators or lecturers in applying models or approaches must be adapted to the demands of 21st-century skills.

This study aimed to determine the communication skill profile of Elementary Teacher Education (ETE) students enrolled in natural science online learning-based STEM. Pre-experimental research with a one-shot case study design was used in this study. The study's sample consisted of 25 ETE students from a university in Cimahi. Observation and documentation were the techniques used in this study. The paired sample t-test was used to analyze the data. The descriptive analysis and hypothesis testing with the t-test were used to check the data validity. The findings of this study revealed that (1) there is an effect of STEM-based online science learning on ETE students' communication skills, (2) that most students are still in the Intermediate category for written communication and "does not meet the Standards" for oral communication skills, and (3) that students' communication skills in STEM-based science online learning still need to be optimized. The study's findings suggest that ETE lecturers in Indonesia should broaden their knowledge and perspectives in STEM-based learning and communication management. Second, ETE lecturers in Indonesia must take the assessment of communication skills more seriously. Last but not least, the government, with the help of researchers, must devise an excellent assessment system to overcome time constraints. The results of this study revealed that STEM-based online science learning is being implemented.
