Penalaran Kuantitatif, Gender, Quantitative ReasoningAbstract
Penelitian kualitatif deskriptif ini bertujuan untuk mendeskripsikan profil penalaran kuantitatif siswa SMP ditinjau dari gender. Untuk mencapai tujuan tersebut, digunakan tiga instrumen, yaitu tes kemampuan matematika untuk menentukan subjek penelitian dan tugas penalaran kuantitatif dan pedoman wawancara untuk mengumpulkan data profil penalaran kuantitatif subjek penelitian. Profil penalaran kuantitatif ditinjau dari gender adalah sebagai berikut: (1) subjek perempuan dan subjek laki-laki memahami informasi kuantitatif dengan berbagai bentuk; (2) subjek laki-laki merumuskan persamaan dari hasil interpretasi informasi kuantitatif yang diberikan secara implisit; (3) dari hasil interpretasi, subjek perempuan menyebutkan terdapat dua kuantitas sedangkan subjek laki-laki menyebutkan terdapat tiga kuantitas yang terlibat dalam masalah soal dan keduanya menyebutkan beberapa hubungan kuantitas-kuantitas tersebut; (4) subjek perempuan menggunakan metode geometri dengan menerapkan suatu sifat, sedangkan laki-laki menggunakan metode aljabar dengan menyusun dan menyelesaikan suatu persamaan; (5) keduanya memperkirakan jawaban dan memeriksa kemasuk-akalannya dengan berbeda sesuai dengan metode yang digunakan; (6) keduanya mengkomunikasikan informasi kuantitatif secara lisan maupun tulisan; (7) kedua subjek mengenali keterbatasan metode yang digunakan dalam menyelesaikan soal.
This research was a descriptive qualitative reseach. The research objectives were to describe profile of the quantitative reasoning of female and male junior high school students. To reach this objective, the reseacher employed three instruments, namely a mathematical ability test to determine participants and quantitative reasoning tasks and a interview guidance to collect data of profile of the quantitative reasoning of the students. Profile of the quantitative reasoning based on gender were: (1) the both of participants understand quantitative information given in various formats; (2) the male participant can formulate an equation as a product of interpreating quantitative information which given implicitly; (3) as a result of interpratation, the female participant said that there were two quantities, whereas the male participant said there were three quantities involved in a problem and both of them mentioned several relationships among the quantities; (4) the female employed the geometry method by applying the properties of parallel lines and a two-line intersection, whereas the male employed algebra method by formulating and solving an one-variable linear equation to solve a problem; (5) both of them estimated answers and checked its reasonableness in different ways appropriate to the method that each employed; (6) both of them communicated quantitative information in verbal and written ways; (7) both of participants recognised a limitation of each own method that they umployed to solve a problem.
