Penelitian ini bertujuan untuk mengetahui efektivitas virtual lab berbasis STEM sebagai media praktikum alternatif dalam meningkatkan literasi sains siswa dengan perbedaan gender. Penelitian ini menggunakan desain one Group pretest-posttest yang terdiri dari kelas 7B dengan jumlah siswa 29 orang perempuan dan kelas 7D dengan jumlah siswa 30 orang laki-laki. Teknik pengambilan data menggunakan metode observasi, angket, dan tes. Efektivitas virtual lab berbasis STEM dianalisis dengan Independent-samples t test kemudian dihitung nilai effect size. Hasil penelitian menunjukkan bahwa terdapat perbedaan hasil peningkatan literasi sains siswa kelas perempuan (7B) sebesar 0,46  dan kelas laki-laki (7D) sebesar 0,29 dengan keduanya dalam kategori sedang. Nilai effect size penggunaan virtual lab berbasis STEM pada domain konten dan kompetensi sains sebesar 0,39 dengan kategori sedang dan domain sikap sebesar 0,75 dengan kategori tinggi Kata kunci: virtual lab, STEM, literasi sains, gender Stem-Based Virtual Lab Effectiveness in Improving the Scientific Literacy of Students with Gender Differences AbstractThis study aimed to know theeffectiveness of STEM-based virtual lab in improving the scientific literacy of students by gender differences.The design of this research one group pretest-posttest consisting of class 7B by the number of students 29 women and 7D class by the number of students 30 men.The data Ade collected through questionnaires, observations, and tests. The effectiveness of STEM-based virtual lab was analyzed through Independent-samples t test then calculated the value of effect size. the results showed that there are differences the resulting increase inscientific literacy class students women (7B) of 0.46 and a class of men (7D) of 0.29 with both of them in the medium category.The value of effect size using STEM-based virtual lab on the science content domain and competencies of 0.39 with the moderate category and attitude domain of 0.75 to a high category.Keywords: virtual lab, STEM, Scientific literacy, gender

The difference between learning using one sensory ability (e.g. reading text or hearing or looking at the pictures only) and two or more (e.g. reading text equipped by sound and visualized by animation; and even allows children to get involved directly in the process of learning) was that the low ability in memorizing. MESE (Multimedia in Education for Special Education) was a multimedia application developed for reading for children with intellectual disability. This research aimed to find out MESE effectiveness in learning related to reading skills and memorizing. MESE was very attractive and had interactive ability that provided opportunity to learners for independent study. The method used was SSR (Single Subject Research). The results showed that learning by using MESE application enhanced reading skill and memorizing. The analysis of the student’s worksheet of reading ability and memorizing showed positive result though several sessions showed a decline and or a stable.

The rapid development of digital technology has stimulated teachers with the number of competencies called digital literacy. The purpose of this study was to describe gender differences in digital literacy among prospective physics teachers. This research was conducted using a descriptive method involving 71 prospective physics teachers at a university in Tasikmalaya. They consisted of 31 males and 40 females with age 19-21 years old. Data was collected using valid digital literacy tests and interview. The collected data was processed by determining the average score of male and female students then analyzed through interview. The results showed that the mean of male’s digital literacy was higher than female. The males had a mean 57 (moderate category) and the females had a mean 53 (low category). There was a difference in digital literacy between males and females prospective physics teachers. These distinctions were influenced by their tendency in using digital technology. Some recommendations were delivered to prospective physics teachers, especially for females. They should effectively increase their digital technology use and appropriate training in the use of digital technology is needed to achieve a higher level of digital literacy.
