Abstract

This study aims to describe statistical literacy skills based on the field of expertise and curiosity of grade XII student of SMK Komputama Jeruklegi. The type of research used is qualitative descriptive research. Sampling was done by purposive sampling technique. The study took four subjects from each category in each field of expertise in SMK Komputama Jeruklegi. Data collection using questionnaires, statistical literacy tests, and interview guidelines. The validation test used is a technical triangulation test. The results showed that of the two fields of expertise taken, students achieved two to four indicators of statistical literacy. For students of information and communication technology with curiosity is very high can meet all indicators of statistical literacy ability. Students with high curiosity meet indicators understand the data, present the data and draw conclusions. Students with curiosity are meeting indicators understanding the data and drawing conclusions. While students with low curiosity meet the indicator presents the data and draws conclusions. Then the results of students in the fields of business expertise and management show that students with very high curiosity and high meet indicators of understanding data, presenting data, and drawing conclusions. Students with curiosity are meeting indicators understanding the data and presenting the data. Whereas students with low curiosity meet the indicators understand the data and draw conclusions. This research is expected to contribute to students' statistical literacy skills, so that they can provide an overview of future research.

Abstract

The inability of students to master the material concept of the advanced differential equation gives rise to internal and external factors that are formed in them so that it needs to require encouragement as effective use of learning media so that learning in the classroom becomes increasingly attractive to students. We used online learning media as zoom, offline or online learning videos, E-learning, and others. This research aimed to identify and describe students learning difficulties in advanced differential equation courses in terms of the use of learning media during the Covid-19 pandemic. The type of research used is qualitative research, with a descriptive approach. Results showed that students have great difficulty learning numerical methods to solve first-order differential equations from all three sub-chapters of matter. In this material, students are still less careful in answering questions (58,1%). Because students could not identify the type of methods used to solve problems, students need online learning media that are effective for math learning, such as offline learning videos (71%), as a solution to save internet quotas. So, this research is useful for educators/lecturers in observing the condition of student learning difficulties given the use of learning media used to motivate students to be active in learning advanced differential equation courses during the Covid-19 pandemic.

Abstract

This research aimed to describe students' mathematical reasoning ability viewed from spatialintelligence in SMP Negeri 3 Banyumas. This was conducted in Grade VIII A SMP Negeri 3Banyumas. The method of this research was qualitative descriptive. The sampling techniquewas purposive sampling. The subjects were divided into three groups; group with high spatialintelligence, group with medium spatial intelligence, and group with low spatial intelligence.The techniques of collecting data were test and interview. The result of this research showsthat: (1) Students with high spatial intelligence were able to master six indicators ofmathematical reasoning ability such as proposing presumption, finding the pattern to makegeneralization, drawing conclusion from the statements, proving the truth of a solution, doingmathematic manipulation, and checking the validity of an argument; (2) Students withmedium spatial intelligence were able to master four indicators of mathematical reasoningability such as proposing presumption, finding the pattern to make generalization, doingmathematic manipulation, and checking the validity of an argument; and (3) Students withlow spatial intelligence were able to master three indicators of mathematical reasoning abilitysuch as proposing presumption, drawing conclusion from the statements, and doingmathematic manipulation.KEY WORDS: Mathematical Reasoning Ability, Spatial Intelligence

Abstract

Tujuan dari penelitian ini adalah untuk menggambarkan penguasaan kemampuan matematika siswa pada materi fungsi, dan mendeskripsikan kemampuan penalaran dan komunikasi pada setiap skor dengan menggunakan rubrik penilaian unjuk kerja. Metode deskriptif kuantitatif digunakan dalam penelitian ini dikarenakan terdapat relevansi pada proses awal sampai kesimpulan yang tersusun. Adapun, sampel yang diambil adalah sebanyak 77 mahasiswa tingkat satu pada salah perguruan tinggi swasta tahun akademik 2014/2015. Berdasarkan hasil penelitian dapat disimpulkan bahwa: 1) kemampuan matematis mahasiswa secara klasikal telah mencapai ketuntasan yang ditandai dengan nilai rata-rata diatas Kriteria Ketuntasan Minimum (KKM), sebaliknya ketuntasan secara individual hanya mencapai 63%. 2) Kemampuan mengkomunikasikan gagasan ke dalam bentuk digram matematika secara keseluruhan hampir lengkap, jelas, efisien, dan tidak ragu-ragu. Sedangkan, untuk kemampuan menggunakan ide-ide dan prosedur penalaran matematika untuk menarik kesimpulan yang telah dibuktikan, secara keseluruhan sebagian besar adalah benar, walaupun, masih terdapat kesalahan perhitungan yang serius. Kata Kunci : penalaran matematis, komunikasi matematis.

Abstract

This study aims to determine the activities of students in learning subjects through True or False strategy of graph theory by media index cards. Observations show a more focused student activity because students already know the material of what will be learned through the index cards that they get in early learning, and they also know the form of matter or issue that they get when studying the learning material on which they will carry. Students focus on the material presented by the lecturers. At the end of the students' learning spirit in concluding that material has been obtained. Lecturers also seem satisfied when getting feedback from students on material that has been given to the student lecturer. Keyword: true or false, cards, graphs, media
