Abstract

Penelitian ini bermaksud membandingkan kemampuan berpikir kreatif siswa yang diajar dengan model pembelajaran problem posing berbantu video animasi dengan siswa yang diajar dengan pembelajaran langsung pada materi lingkaran. Riset ini merupakan riset kuantitatif dengan mempergunakan metode eksperimen dengan rancangan penelitian Statistik Group Comparison. Populasi riset ialah siswa kelas VIII SMP Ma'arif 1 Metro. Chuster random sampling adalah teknik pengambilan sampel yang dipakai dalam riset ini. Sampel diambil dari dua kelas yaitu kelas VIIIA (kelas eksperimen) dan kelas VIIIB (kelas kontrol). Data riset ini dikumpulkan menggunakan tes dengan instrumen berupa soal uraian serta dokumentasi. Analisis data yang digunakan dalam riset ini adalah uji-t dua sampel independen. Analisis data dengan mempergunakan uji-t pada SPSS menghasilkan nilai signifikansi 0,000 < 0,05, menolak dan menerima H1, menunjukkan bahwa model pembelajaran problem posing berbantu video animasi lebih efektif digunakan dibandingkan pembelajaran langsung dalam meningkatkan kemampuan berfikir kreatif siswa.

Abstract

Mathematics is a subject that exists at all levels of study and requires the ability to think logically, organize, and demonstrate. One of the materials that require this ability in mathematics is the limit function material. The boundary functional material becomes the basis for mastering the next material, namely derived material. The fact that students do not have a solid understanding of the limit function literature indicates that students do not do well academically at this level. This is because students have difficulty and make mistakes in understanding concepts, facts, and procedures in the limit function literature. Vygotsky's theory can be applied to the matter of limit functions. Vygotsky applies the Zone of Proximal Development (ZPD) which is a level of development slightly above a person's current level of development. When children have learning difficulties, Vygotsky suggests that teachers can use scaffolding as support or assistance through someone who is more proficient in mastering the material to help solve problems, problems for people with higher levels of cognitive development.

Abstract

The purpose of this study was to determine students' written communicative competence in solving key problems of SPLDV in everyday life. This study uses descriptive qualitative research. These data are determined by testing. Subjects in this study consisted of her three undergraduates from UTS results. The three students were made up of representatives of high, middle and low ability students. In addition, students are given test questions supported by the SOLO taxonomy of SPLDV materials, which are analyzed according to indicators of mathematical communicative competence. The bottom line is that students with good math skills are able to give correct and correct answers, but have not yet reached the level of extended abstraction. A student with moderate writing ability can demonstrate the correct procedure, but still has problems using and processing the information, so the answers are wrong and only reach the polystructural level. Students with low mathematics ability do not solve problems, only part of the problem is presented, so they only reach the monostructural level and most of the answers are wrong.
