The use of varied learning models by history teachers will facilitate teachers and students in implementing and following the learning process. This study aims to determine the learning process and the use of learning models used by history teachers. This study uses a qualitative methodology with an observation and interview approach conducted at two high schools, Dian Didaktika High School and SMA Negeri 2 Depok. From the results of the study it can be seen, that the history teacher at the two schools has carried out the learning process using a scientific approach. There is no difference in the selection of learning strategies, both of them use the contextual teaching learning model. The difference between the two is in the selection of learning methods, where the history teacher Dian Didaktika uses the method of learning project base learning and the history teacher of SMA Negeri 2 Depok uses a method of learning outside the classroom by visiting museums.

Currently the 2013 curriculum applies scientific approach in learning activities to develop self-potential by sharpening the mindset of students to be more active and creative. To realize these goals, learning methods and media must be carefully selected. This research will produce an e-module based on a scientific approach with probing and prompting questions for hydrocarbon material. The probing and prompting questions are used to familiarize students with answering questions so that the development of students' thinking patterns can be maximized. Research Development (R D) is a type of research that is used with 4-D as a development model.  The 4-D stages include: define, design, develop and disseminate. The disseminate stage was not carried out due to time and cost limitations. The research was only carried out until the develop stage, namely the validity and practicality test. Validity and practicality sheets were used as data collection instruments. The e-module validation was carried out by 5 validators, while the practicality of the e-module was carried out by 3 chemistry teachers and 30 students of SMAN 12 Padang. The research data processing used the Kappa Cohen formula. The e-module validity values obtained were 0.87 and the practicality values by teachers and students were 0.88 and 0.83.  Based on these three values, the hydrocarbon e-module based on a scientific approach with probing and prompting questions is declared valid and practically used in the learning process. Saat ini kurikulum 2013 menerapkan tahapan saintifik dalam kegiatan pembelajaran  untuk mengembangkan potensi diri dengan mengasah pola pikir siswa menjadi lebih aktif dan kreatif. Untuk mewujudkan tujuan tersebut, metode dan media pembelajaran harus dipilih dengan cermat. Penelitian ini akan menghasilkan e-modul berbasis pendekatan saintifik dengan pertanyaan probing dan prompting untuk materi hidrokarbon. Pertanyaan probing dan prompting digunakan untuk membiasakan siswa dalam menjawab pertanyaan sehingga pengembangan pola pikir siswa dapat dioptimalkan. Research development (R D) merupakan jenis penelitian yang digunakan dengan 4-D sebagai model pengembangannya. Tahapan 4-D meliputi: define, design, develop dan disseminate. Tahap disseminate tidak dilakukan karena keterbatasan waktu dan biaya. Penelitian hanya dilakukan sampai tahap develop, yaitu uji validitas dan praktikalitas. Lembar validitas dan praktikalitas digunakan sebagai instrumen pengumpulan data. Validasi e-modul dilakukan oleh 5 orang validator, sedangkan praktikalitas e-modul dilakukan oleh 3 orang guru kimia dan 30 orang siswa SMAN 12 Padang. Pengolahan data penelitian menggunakan formula Kappa Cohen. Nilai validitas e-modul yang didapatkan sebesar 0,87 dan nilai praktikalitas oleh guru dan siswa sebesar 0,88 dan 0,83. Berdasarkan ketiga nilai tersebut, maka e-modul hidrokarbon berbasis pendekatan saintifik dengan pertanyaan probing dan prompting dinyatakan valid dan praktis digunakan dalam proses pembelajaran.

The ability to play the piano with a variety of timbres requires a performer to have advanced pianistic skills. Little is known about how these skills are acquired and developed in piano lessons and what the role is of elements such as concepts, technique, sonic outcomes, and bodily movements. To investigate the teaching and learning of piano timbre, the lessons of three pairs of university-level teachers and students (two teachers and three students) were observed, during which they behaved as usual in the first two lessons and were asked to use a dialogic teaching approach in the third lesson. Verbal communications of teachers and students about timbre were coded and analyzed, aiming to gain insight into the teaching/learning process of piano timbre and the roles of embodiment and teacher–student interaction in the context of higher music education. The results suggest that piano timbre is not learned through imitation or as “fixed” and objective knowledge, but as a co-constructed conception between the teachers and the students. The meaning of timbre goals in piano lessons is enacted through “in-the-moment” bodily experience and embodied through performance actions. This study contributes to the understanding of piano timbre as a multifaceted phenomenon and illustrates the teacher's role in developing the student's mind–body integration involved in tone production.
