This study aimed to develop diorama learning media in social learning for grade IV elementary schools and to determine the feasibility of diorama media. This research used research and development (R&D) methods using the model 4D (Define, Design, Develop, Disseminate). This development produced a product that has been adapted to the basic competencies used, namely identifying economic activities and their relationship to the field of work. Data were collected through questionnaires and trials. The feasibility of diorama learning media was obtained from the validation results and students' and teachers' responses. The validation was carried out by media experts and material experts. The trial conducted was limited to 23 grade IV elementary school students. The trial results by material experts were in the very feasible category, and the validation by media experts was in the very feasible category. Similarly, the validation from media experts obtained a very feasible category. The results of this research showed that the diorama media was very feasible for social studies learning at grade IV elementary schools.

The use of the first language (L1) in the English as a foreign language (EFL) classroom is becoming an on-going debate. A newly growing view to the use of L1 in the foreign language (FL) classroom called translanguaging views that by utilizing the L1 along with the TL in FL classroom is considered as functional practice of languages rather than an impediment in FL learning. Accordingly it is necessary to find out the functions of teachers' practice of translanguaging in the EFL classroom since this view has not been much researched yet. Related to this, the current study was intended to find out the functions of the EFL teachers' translanguaging and to find out the teachers' reasons for the use of translanguaging. This study followed qualitative descriptive interactive research design, and the subjects consisted of three English teachers at the 7 th grade classes at two junior high schools in Singaraja. The data were collected through observations and interviews and were analyzed descriptive qualitatively. The results of this study showed that there were 3 functions of translanguaging. The most frequent function was related to knowledge construction, followed by classroom management, and interpersonal relations. There were 9 reasons for the teachers' use of translanguaging, namely: to facilitate students' understanding, to provide L1 and TL comparison, to elicit students' responses, to attract students' attention, tomanage students, to promote discipline, to develop deeper personal relationship, to create secure classroom atmosphere, and to make the class more interesting. In sum, the use of translanguaging plays a number of functions in the EFL classroom but it should be considered also the 'optimal' use of it in EFL learning process because the overuse of L1 might bring negative impact.
