Abstract

This study aims to examine the development of an interactive learning model using Visual Basic Application for Microsoft excel with ethnomathematical content on fractions, to improve primary school students’ mathematical reasoning abilities. The research method used is development through the stages of conducting preliminary studies and literature, designing interactive learning models, conducting FGDs, producing initial designs of interactive learning models, conducting limited trials in one primary school, making revisions, conducting extensive trials in four primary schools, producing trial in another primary school. The last obtaining a final model and conducting socialisation. The last, it provides a test of mathematical reasoning ability. The research subjects were teachers and students in six primary schools. The research instruments were interviews, validation sheets, documentation, learning observation sheets, questionnaires and mathematical reasoning ability test.  The assessment criteria for the developed learning model include syntax, social system, principle of reaction, supports system and instructional impact. The results showed that 1) Development of VBA-assisted and ethnomatematically-loaded interactive learning models go through two major stages, namely product development and validation  2) The Interactive learning model was declared very valid; 3) The responses of teachers and students were generally positive; 4) The achievement of students’ mathematical reasoning abilities after gave learning with an interactive model using VBA for Microsoft Excel with ethnomathematical contents better than using ordinary learning.

Abstract

Penelitian ini bertjuan untuk menelaah bagaimana hubungan antara kemampuan berpikir kreatifmatematis dengan motivasi belajar siswa dalam pembelajaran yang menggunakan pendekatanCreative Problem Solving (CPS). Metode penelitian yang digunakan adalah metode kuasieksperimen, dengan cara mengambil dua kelas yang berbeda, kemudian kelas pertamamendapatkan pembelajaran dengan CPS dan kelas kedua menggunakan pembelajaran biasa.Populasinya adalah seluruh siswa SMP di Kota Cimahi, dengan sampel diambil dua kelas. Keduakelas diberi pretes agar mengetahui kemampuan awal mereka, selanjutnya kelas eksperimendiberi pembelajaran dengan CPS dan kelas kontrol diberi pembeljaran biasa, dan terakhir keduakelas diberikan postes dan angket motivasi belajar yang mana data tersebut akan diolah dandianalisis korelasinya menggunakan Product Moment Person. Hasil penelitian menunjukan adanyahubungan yang signifikan antara kemampuan berpikir kretif matematis dan motivasi belajar siswadalam pembelajaran matematika

Abstract

The process of learning mathematics is determined by cognitive aspects and requires an affective domain. The affective domain is essential in developing mathematical abilities to solve mathematical problems. This study aims to analyze the effect of mathematical resilience (RM) and habits of mind (HOM) on socio-mathematical norms (SMN) in mathematics learning. The research method used is quantitative, with survey techniques and structured inquiry models. The sample in this study was 100 high school students in the DKI Jakarta area. Data analysis was performed using the structured equation model (SEM) using SmartPLS software. This research uses eight items of mathematics resilience instrument, ten items of habits of mind instrument, and 12 items of socio-mathematical norm instrument. Each instrument has four alternative answers with a Likert scale. The results of the study concluded: 1) there is a positive impact of mathematical resilience on socio-mathematical norms; 2) there is a positive impact of habits of mind on socio-mathematical norms; 3) there is a positive impact of mathematical resilience on habits of mind; 4) there is a positive impact of mathematical resilience on sociomathematical norms mediated by habits of mind.
