E-Chemistry Magazine that has been developed is a teaching materials that utilizes the development of technology to improve the quality of a learning process. The objective of this research is to develop an interactive e-chemistry magazine for the acid-base course unit. The method used in this research is the Plomp model research and development (R&D) design. This research consists of three phases, (a) preliminary research phase, (b) prototype or development phase, and (c) assessment phase. The result of this research indicates that acid and base e-chemistry magazine is considered to be strongly valid by the content and media experts. The responses from teachers and students regarding the acid and base e-chemistry magazine are very good and very interesting. This suggests that the production of acid and base e-chemistry magazine meets the decent criteria to be used as interactive teaching materials in the learning of chemistry for the acid-base course unit.
E-module reaction rate based guided inquiry has been developed using the Kvisoft flipbook maker. The e-module is developed using the Plomp development model which consists of three phases namely, the initial investigation phase, the prototype making phase, and the assessment phase. The results of the material validation obtained an average percentage for the content aspects, presentation aspects, language aspects, and graphics aspects are 87.46%, 86.63%, 95.80%, and 81.5% with a very valid category. While the result of media validation obtained an average percentage for the cover design aspect, the content design aspect and the display aspect are 100%, 97.80%, and 85.6% with a very valid category. The result of t h e u s e r response test obtained average percentages are 88.34% and 86.25% with a very good category. Based on the result of the validation and user response test can be concluded that the e-module reaction rate based guided inquiry is feasible to be used in the chemistry learning process as independent teaching material.
Abstrak -Penelitian ini bertujuan mengetahui apakah model pembelajaran Creative Problem Solving tipe Treffinger dapat meningkatkan berpikir kreatif peserta didik pada pokok bahasan larutan penyangga di SMAN 9 Pekanbaru. Penelitian ini menggunakan rancangan penelitian Design Randomized Control Group Pretest-Posttest dengan instrumen pengumpul data berupa soal essay dan angket penilaian sikap kreatif peserta didik. Sampel penelitian terdiri dari 2 kelas, yaitu kelas XI MIA 4 sebagai kelas eksperimen dan kelas XI MIA 6 sebagai kelas control yang telah diuji normalitas menggunakan uji Liliefors dan uji homogenitas menggunakan uji kesamaan dua rata-rata. Hipotesis penelitian diuji dengan menggunakan uji-t pihak kanan. Hasil penelitian menunjukkan bahwa penerapan model pembelajaran Creative Problem solving tipe Treffinger dapat meningkatkan berpikir kreatif peserta didik pada pokok bahasan larutan penyangga dengan t hitung = 2,07 > t tabel = 1,67 dengan α = 0,05.
Abstrak: Penelitian ini bertujuan untuk mengembangkan Lembar Kegiatan Peserta didik (LKPD) Berbasis Hierarki Konsep pada Pokok Bahasan Hidrolisis Garam yang valid berdasarkan aspek kelayakan isi, kebahasaan, sajian dan kegrafisan. Jenis penelitian ini adalah penelitian pengembangan (research and development) dengan proses pengembangan mengacu kepada model pengembangan 4D. Objek penelitian ini adalah bahan ajar yaitu Lembar Kegiatan Peserta Didik (LKPD) berbasis hierarki konsep. Instrumen pengumpulan data adalah lembar validasi yang diberikan kepada tiga validator dan dari hasil analisis data diperoleh validitas pada aspek kelayakan isi, kebahasaan, sajian dan kegrafisan berturut-turut yaitu sebesar 89,28%, 91,67%, 93,75% dan 87,50% dengan kategori valid. LKPD yang telah valid menurut validator diujikan kepada 20 orang peserta didik dan mendapatkan hasil respon dengan persentase sebesar 91,07% dengan kategori sangat positif dan dinilai kepraktisannya oleh dua orang guru dan mendapatkan hasil respon dengan persentase sebesar 93,75% dengan kategori sangat praktis. Berdasarkan hasil analisis data dapat disimpulkan bahwa Lembar Kegiatan Peserta Didik (LKPD) berbasis hierarki konsep yang dihasilkan dinyatakan valid dan dapat digunakan pada mata pelajaran kimia SMA pokok bahasan hidrolisis garam.
