The purpose of this experiment was to comprehensively examine whether innovative Brain-Based Learning and Treffinger learning was effective for developing mathematical creative thinking ability at junior high school. The research design was a quasi-experimental non-equivalent control-group design. The population was all grade VIII students at Junior High School in the 2019/2020 school year. The samples were two classes determined by a randomized class. Data collection techniques with tests. Data analysis were using the z-test and the t-test. The results of this study were the percentage of students in the class that applied the Treffinger learning achieved classical completeness and the mean of creative thinking ability of students in the class that applied the Treffinger learning was more than the mean mathematical creative thinking ability of students in the class that applied Problem-Based Learning. The percentage of students in the Brain-Based Learning class achieved classical completeness and the mean mathematical creative thinking ability of students with Brain-Based Learning was higher than the students with Problem-Based Learning. There is no significant mean difference between the students’ mathematical creative thinking ability in the class that apply Brain-Based Learning and Treffinger learning. This research concludes that innovative learning Brain-Based Learning and Treffinger learning is effective for developing mathematical creative thinking ability at junior high school.
Banyaknya masalah dikarenakan limbah tekstil mendorong industri untuk menerapkan eco fashion. Langkah yang potensial adalah dengan teknik ecoprint. Ecoprint adalah proses pentransferan warna dan bentuk ke kain melalui kontak langsung. Ecoprint dalam penelitian ini menggunakan teknik steam medium print dengan beberapa zat warna alam, yakni secang, tingi, tegeran, kulit manggis dan merr. Tujuan penelitian ini untuk mengetahui pengaruh zat warna alam terhadap kualitas hasil ecoprint pada aspek warna dan motif. Penelitian ini menggunakan metode eksperimen. Observasi dilakukan melalui uji laboratorium dan uji organoleptik dengan sampel Klaster Batik Kota Semarang. Teknik analisis data menggunakan statistik deskriptif dan inferensial. Analisis arah warna pada latar menunjukkan bahwa zat warna secang memperoleh warna peach-punch, tingi memperoleh warna tangerine-ginger, tegeran memperoleh warna blonde-lemon, kulit manggis memperoleh warna egg nog-sand, dan merr memperoleh warna daffodil-mustard. Uji grey scale menunjukkan bahwa tidak ada pengaruh yang signifikan. Sedangkan uji staining scale dan estetika motif menunjukkan ada pengaruh yang signifikan. Hasil uji grey scale dan staining scale terbaik diperoleh zat warna kulit manggis dengan ratarata 4,17 (baik) dan 4,25 (baik). Sedangkan estetika motif terbaik diperoleh zat warna tegeran dengan rata-rata 3,97 (cukup baik).
This study aims to validate that measurement methods in early childhood are very important, but many institutions do not apply this method. We are trying to use the medium of stacking to prove that the teaching of early childhood measurement is important to them. The main point of his research is children with problem solving, and also accurate donuts media as a teaching medium for measurements related to the size of the donut itself. And also the arrangement of such donuts from the largest to the smallest. The method we use is the class action method and the results of the research show that children aged 4-6 years are able to learn and understand the size of the stacking donut media, while for children aged 1-3 years still need direction and guidance on the commands from the stacking donut media.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
