Authentic U-Fraction in Authentic Learning Environment

In this study, we developed a tablet-based application, namely Authentic U-Fraction to assist elementary school students in learning fractions with authentic contextual support. In this study, an experiment was carried out to investigate the effects of the students’ learning behavior toward the fraction learning achievements using Authentic U-Fraction. Three topics of fractions included are fractions concept, fraction simplification, and fraction addition/subtraction. Totally 54 fifth-grade students were assigned and divide into two groups, one experimental group, and one control group. The control group learned fraction using traditional teaching method and paper-based assignment, while the experimental group using Authentic U-Fraction in an authentic context. After the experiment, the result showed that the experimental group performed better than the control group, especially in understanding fraction and fraction representation. The reason was that by taking the picture, making fraction representation from the picture, and making annotation facilitated students to learn fraction using Authentic U-Fraction. Authentic U-Fraction also helped students to do more practice by themselves and fully explain their solutions, but it does not affect their learning achievement. Because besides students did more practice, they also need to make a complete annotation that includes three different representation: linguistic, logic mathematics, and visual representative. More students did practice with complete annotation higher their learning achievement. Application of three scaffoldings on students’ peer assessment also revealed that meaningful peer assessment could correlate to the students’ learning achievement that also strengthened by the teacher assessment score that also has a higher correlation to the learning achievement from the assessment of assignment side. A Multiple regression result shown that teacher assessment score could strongly predict the posttest score. Overall, students satisfied with Authentic U- Fraction because it is easy to use, easy to learn, and it facilitates the students to learn fraction in an authentic context. In the final, the result of this study contributes essential implications along with conclusion and suggestion for future research

One way to make this happen is by implementing Pawon Urip. Pawon Urip is the local wisdom of the Lumajang Regency which is bound by the concepts of kinship, mutual cooperation, empathy and also solidarity among residentsThe aim of this paper is to elaborate the ways Pawon Urip in Lumajang Regency, East Java uses and develops the local values of gotong royong and solidarity toward immediate circles of social connections to deal with stunting as their common problem. This paper is a qualitative research on Pawon Urip. The main data will be collected through interviews done with some Pawon Urip activists and also its members. The secondary data will be collected in the forms of news and reports on Pawon Urip activities, stunting statistical data, and other related data. The data will be analyzed thematically to formulate the golden thread of the local wisdom in dealing with common problem of stunting. The results of this study are the application of Pawon Urip in Kloposawit Village to help the community meet nutritional needs during the COVID-19 pandemic and can support sustainable food consumption and improve nutritional status. It is hoped that this paper might provide an example of a best practice in the mitigation of stunting using local wisdom

Pemanfaatan Saung Intelektual untuk Meningkatkan Kemampuan Belajar Anak Tidak Sekolah

Kecamatan Tanon Kabupaten Sragen terdapat Desa Tanon. Mayoritas masyarakat yang tinggal di Desa Tanoni bermata pencaharian di bidang pertanian sebagai petani, buruh tani, buruh harian lepas, dan dalam beberapa hal sebagai wiraswasta. Namun demikian banyak orang tua yang tetap menyekolahkan anaknya ke sekolah menengah atas meskipun sebagian besar dari mereka yang bekerja di industri dan berpendidikan SLTA atau SLTP. Anak-anak memang ditakdirkan untuk belajar, namun kenyataannya banyak orang tua yang terlalu disibukkan dengan bekerja, baik di ladang sendiri maupun sebagai buruh tani. Tujuan dari kegiatan ini adalah: 1) Meningkatkan pendidikan berbasis nonformal dengan mendirikan Saung Intelektual. 2) Mewujudkan saung intelektual yang berangkat dari permasalahan dan potensi masyarakat. 3) Penguatan P5 (program penguatan profil pelajar Pancasila) dalam mewujudkan generasi terdidik. 4) Pembekalan dan pencerdasan mengenai seks education dan penanaman nilai moral serta agama sejak dini. 5) Menyadarkan pentingnya digitalisasi dalam upaya peningkatan perekonomian masyarakat.
