The future competence of the 21st century requires students to be able to utilize Information and Communication Technology (ICT). One of ICTs used by students is smartphone. To get the smartphone benefits used by students, a medium of learning is needed in the form of modules on smartphone operating system. Hopefully, it can make the students feel more interested and motivated in learning biology. The purpose of this study was to develop multimedia mobile learning modules based on android operating system which contains biodiversity material for senior high school students of class X. The research was conducted in September 2015 to January 2016. The research method used was a research and development. The validation test results of subject expert, a linguists and media experts testing obtained scores of 84%, 80.57% and 63%. The trial test results of initial and primary use of students was 81,41% and 81,15%. Next result was a trial test from biology teachers with 87.50%. Pre test obtained an average score 83.98 while the post test gained an average score of 87.23. The conclusion of this research and development was the multimedia mobile learning modules of biodiversity material based on android operating system for senior high school students of class X has been developed, got a good interpretation score and increase student learning outcomes.
The purpose of this study was to measure student knowledge and attitudes in conservation of mangroves and coral reefs, introducing and applying Environmental Education Community Network (EECN) to students in wider scale. The method used in this research is a descriptive method and used a survey for gathering data. Samples were selected with simple random sampling in several schools and Jakarta State University. The results showed Average score of knowledge students from all levels were with low category. Average score of attitudes students from all levels were with high category. Students' knowledge was still low and attitudes in terms of mangroves and coral reefs were high. This result showed that students need a model that could enhance knowledge and attitude to conserve mangroves and coral reefs. EECN is one model that have the potential to empower students' knowledge and attitude in protecting the environment.
Penelitian ini mengkaji motivasi belajar siswa selama pandemi dalam proses belajar dari rumah. Dalam proses belajar, motivasi sangat dibutuhkan. Motivasi dapat timbul dari intrinsik (dalam diri individu) maupun ekstrinsik (luar individu). Kedua faktor ini sangat penting dan berkesinambungan dalam meningkatkan motivasi siswa. Selama pandemi COVID-19, proses pembelajaran dilakukan dari rumah, sehingga motivasi belajar dapat berpengaruh dari beberapa faktor. Dari hasil penelitian yang didapat, banyak faktor-faktor yang tidak mendukung proses belajar siswa selama pandemi. Faktor-faktor tersebut, diantaranya; kemampuan teknologi, koneksi akses jaringan internet, media pembelajaran yang digunakan, kapasitas siswa untuk pembelajaran online, dan lain-lain, sehingga motivasi belajar siswa berubah menjadi menurun. Dengan demikian, dapat disimpulkan bahwa motivasi belajar siswa selama pandemi dalam proses belajar dari rumah mengalami penurunan.
The analytical thinking skill is a part of the higher order thinking process. The analytical thinking skill is needed to solve a problem in learning process. The analytical thinking has 5 process, there are matching, classifying, analyzing errors, generalizing, and specifying. Group Investigation (GI) model is applied in learning to improve the analytical thinking skill of students in environmental pollution. This research aimed to determine the influence of applying Group Investigation (GI) model on student analytical thinking skill in environmental pollution. This research was held on second semester of academic year 2015/2016 on April until May 2016 in Labschool Kebayoran Junior High School. The kind of this research is a quantitative research with quasi experiment methods. The subject of this research is students in Class VII-B and VII-F Labschool Kebayoran Junior High School. The instrument which used are essay post-test with 15 questions and carried out-learning observations sheet. Based on the result of research, obtained the mean of the analytical thinking skills score test in experiment class is higher than control class, that is 78,46 > 69,43. The prerequisite test shows that data normally distributed and class groups derived from a homogenous population. The hypothesis test uses t-test on 0,05 significant level shows that there is an influence of applying Group Investigation (GI) model on student analytical thinking skill in environmental pollution.
Lab work has become one of the most important activities in learning Biology. Urinalysis requires special treatment because urinalysis using urine as a sample to be analyzed. There have been limitations in implementation of the lab work of urinalysis at high school level. Learning media such as virtual lab work of urinalysis was expected to overcome the limitations. The aim of this research was to develop virtual lab work as learning media of Biology. The research was held at Senior High School 4 Tangerang, using research and development method. Research and information collecting, planning, product development, and try-out and revision were the steps in this research. Instrumen used were questionnaires for need assessment for students, interviews guide for Biology teacher, and questionnaires of feasibility for media expert, material expert, Biology teacher, and students. In the try-out and revision steps, media expert and material expert were involved in feasibility testing, meanwhile Biology teacher and students grade XI at Senior High School 4 Tangerang were involved in field testing. The average percentage of all test products scored 81,76%. The result of this research showed that the virtual lab work of urinalysis could be utilized as one of learning media of Biology for Senior High School grade XI.
