Factors Affecting MERS-related Health Behaviors among Male High School Students

This study was aimed to develop teaching materials about chemical reaction rate which covered materials adapted to A-Level High School students of grade XI in Pioneer International Standard High School (RSMA-BI). The developmental research was adopting the instructional development model 4D which include four stages of development, namely define, design, develop, and disseminate. Instructional materials were written in English consist of seven topics titled: Reaction Rate Concept, The Exchange's Expressions, Rate Law and Reaction Order, Experimental Determination of a Rate Law, Reaction Mechanism, Theories of Reaction Rate, Factors Affecting Reaction Rate. Results of content validation from content experts obtained the average score of 3. 56 of 14 range of scores which means valid / good / decent. Test limited to high school students of RSBI obtained an average score of 3.35 (valid / good / decent). The results of the use of teaching materials obtained a score of 77.8 which is above the minimal passing grade (75). Therefore it can be concluded that the materials were feasible to be used in the classroom.Penelitian ini bertujuan untuk mengembangkan bahan ajar laju reaksi dengan cakupan materi yang disesuaikan dengan A-Level untuk siswa kelas XI Rintisan Sekolah Menengah Atas Bertaraf Internasional (RSMA-BI. Rancangan penelitian pengembangan mengadaptasi model pengembangan bahan ajar Model 4D yang meliputi empat tahap pengembangan, yaitu define, design, develop dan disseminate. Produk pengembangan adalah bahan ajar kimia RSMA-BI kelas XI materi laju reaksi yang ditulis dalam bahasa Inggris menggunakan pendekatan kontekstual. Bahan ajar terdiri atas empat bagian utama yaitu pendahuluan, materi, evaluasi dan penutup. Materi tersusun atas tujuh sub materi yaitu Reaction Rate Concept, The Rates Expressions, Rate Law and Reaction Order, Experimental Determination of a Rate Law, Reaction Mechanism, Theories of Reaction Rate, Factors Affecting Reaction Rate. Hasil validasi isi dari ahli materi diperoleh nilai rata-rata 3,56 dari rentang skor 1-4 dengan kriteria valid/baik/layak. Hasil uji terbatas pada siswa SMA RSBI diperoleh nilai rata-rata 3,35 dari rentang skor 1-4 dengan kriteria valid/baik/layak. Hasil uji penggunaan bahan ajar diperoleh skor sebesar 77,8. Skor ini diatas SKM (Skor Kelulusan Minimal) yaitu 75 sehingga dapat disimpulkan bahwa bahan ajar telah layak dan dapat digunakan dalam pembelajaran di kelas.

Writing Skill

This study aimed to determine the factors affecting writing skill quality and the level of their contribution to help language teachers to formulate more effective strategies using CAT to enhance writing skill. The correlating factors discussed in this research were students’ reading comprehension skill, vocabulary mastery, and attitude toward language. The study applied quantitative approach with simple and multiple correlation and regression techniques. The samples of the study were 100 students taken using stratified random sampling technique from a population of 2000 junior high school students in Surakarta City. The data were collected using multiple choice test for students’ reading comprehension skills and vocabulary mastery, writing assignments, and questionnaires for their attitudes toward the Indonesian language. The findings showed that there are positive correlations between the independent variables, either individually or simultaneously, with writing skill. The individual contribution levels is 44.75% of reading comprehension skill, 27.70% of vocabulary mastery, and 28.5% of attitude toward language. As for the simultaneous correlation of the three determining factors make up to 45.16%. contribution level to writing skill quality. Thus it can be concluded that reading comprehension has the most contribution to writing skill compared to vocabulary mastery and attitude toward language. The identified levels of contribution can be taken into consideration in formulating teaching strategies and materials to enhance writing skill quality.
