Abstract

The article presents a marginal region mathematics teachers' perception of ICT as learning media and the type of ICT media used in mathematics classrooms. A survey was designed including two domains:  the usability and the importance of ICT. A questionnaire was administered to 84 mathematics teachers in marginal regions. The respondents were chosen conveniently based on their accessibility and availability. About 50% of marginal region mathematics teachers do not use ICT in teaching. The most common media used is Microsoft Office software to present teaching materials from internet or digital sources. Using the Rasch model, the data show that mathematics teachers' perception of the usage and importance of ICT as a media of mathematics learning can be categorized as 'medium' level. Mathematics teachers in the marginal regions consider ICT as mathematics learning media to be fairly important.

Abstract

Masalah tentang kemampuan pembuktian matematis telah banyak dikaji oleh para ahli pendidikan matematika baik di dalam maupun di luar negeri. Studi pendahuluan ini untuk memetakan kemampuan pembuktian matematis mahasiswa yang sangat berperan penting dalam mempelajari mata kuliah Analisis Riil dan menganalisis learning obstacle yang dihadapi. Penelitian ini menggunakan pendekatan kualitatif yang lebih menekankan pada kajian interpretative namun dalam hal tertentu akan disajikan secara deskriptif kuantitatif. Data penelitian ini diperoleh melalui tes diagnostik terkait pembuktian matematik bentuk langsung, contrapositive, tidak langsung/ kontradiksi, dan counterexample. Subjek penelitian ini merupakan mahasiswa yang mengikuti mata kuliah Analisis Riil yang dipilih secara purposive sampling. Hasil penelitian ini menunjukkan bahwa: (1) kebanyakan mahasiswa tidak ingat tentang bentuk-bentuk pembuktian; (2) mahasiswa tidak mampu membuat pembuktian matematika bentuk kontrapositif dan kontradiksi; dan (3) dominan mahasiswa tidak mampu mengaplikasikan pembuktian bentuk counterexample. Salah satu faktor penyebab rendahnya kemampuan pembuktian matematis mahasiswa tersebut menurut hasil wawancara dengan mahasiswa, bahwa mereka lupa dan belum terbiasa dalam membuat pembuktian matematika dan belum banyak memahami tentang pembuktian matematika.

Abstract

Manipulative tool is one of the learning media most likely to be used by teachers, including those in marginal regions. This study aimed to determine the perception of mathematics teachers in marginal regions toward using manipulative tools as learning media. This study used surveys designed with two domains: the use of manipulative tools as learning media and the importance of manipulative tools as learning media. The sample for this study comprised 81 teachers who were either currently teaching or had previously taught at the elementary, middle, and high school levels in marginal regions. This study found that the manipulative tools mostly used by mathematics teachers in marginal regions are objects obtained from the surrounding environment (used cans, paperboard, coins, rulers, stones, and sticks). This study revealed that the mathematics teacher's perception of manipulative tools as learning media and the importance of manipulative tools as learning media are generally in the medium category.
