“…The sample used in this study were all students of physics education with a total of 80 people consisting of 40 people for class A and 40 people for class C. The sample used in this study was obtained using a simple random sampling technique. Simple random sampling is the simplest and most commonly used method where every member of the population has an equal chance of being selected as a subject and producing optimal data (Etikan & Bala, 2017;Pal et al, 2018;Sharma, 2017) The data in this study were obtained from quantitative data using a questionnaire. Questionnaires are a useful method for easily collecting data from participants in a study using a rating scale (Owusu-Fordjour, Koomson, & Hanson, 2020;Cagetti et al, 2020).…”

Mathematics physics is often considered by students as a very difficult subject to learn, one of the causes that makes this happen is the lack of learning media that supports students. In addition, most of the existing media use foreign languages, so that in this case Indonesian language learning media is needed, namely the mathematical physics e-module on vector material which is then seen from student responses based on gender differences. This study aims to analyze students' perceptions of the mathematics physics e-module and to analyze students' perceptions based on gender differences in the mathematics physics e-module. This type of research is survey-based research with a quantitative approach. The population of this study was physics education students who contracted mathematical physics with a sample of 80 students. The instrument used in this study was a student perception questionnaire with 15 questions and an interview sheet with 10 questions. The data analysis technique used in this research is descriptive statistical analysis and inferential data analysis using t-test. The results showed that overall students had a positive perception with a perception value of 60% in the very good category and 40% in the good category, whereas when viewed from the gender difference, male students had a perception value of 76.6% in the very good category and 23, 3% in the good category, for female students 50% in the very good category and 50% in the good category. That is, students with gender differences have striking differences in perceptions. Student perceptions can be used as a determining factor in the selection of open materials. From the results, it can be seen that gender differences can help in assessing the products made so that they will support the learning process and increase student learning motivation.

The use of simple random sampling is because researchers expect samples taken at random from each school to be able to represent all students in the school.…”

This research aimed at seeing how the level of perception, interest in learning, and the character of students' environmental care; this study also sees the difference after using the mangrove ecotourism e-module. This quantitative research used the variables of students' perceptions, interests, and environmental care. The sample used was 120 students in 3 different elementary schools, the sampling technique used was simple random sampling. Data analysis used descriptive statistics, ANOVA test, and correlation test. From the results obtained, it can be seen that the students of Islamic boarding schools have the lowest perceptions and interest in learning, namely 46.65 and 32.92. However, to protect the environment, the number of students in Islamic boarding schools is higher than in other students. In the Anova test, elementary school children had different perceptions and interests in learning, while for the character of caring for the environment between Madrasah and Islamic Boarding School children. Other results also showed that perception had a relationship of 20.6% with student interest in learning and 66% with concern for the student's environment. This study's conclusion showed that the e-module can increase the interest and character of students' environmental care.

Green spirituality is very important to do because it can foster good character development for each individual. The concept of caring for the environment and spiritual attitudes that are very closely related also have a significant impact on the character of students. This study aims to examine the spiritual attitude and character of students' environmental care and their effects. This type of research is a mixed method. The sample used is 35 high school students with the sampling technique used is simple random sampling. The instrument used is a quantitative instrument in the form of a questionnaire of students' spiritual attitudes and environmental care characters, while the qualitative instrument is an interview sheet for students' spiritual attitudes. The analysis technique used is descriptive statistical test and linear regression test. The results obtained in this study are that the sample has a fairly good category for each variable, while for the linear regression test, it shows that there is 50.3% of the influence of spiritual attitudes on the character of students' environmental care. These results indicate that there is a significant influence between spiritual attitudes on the students' environmental care character.
