We introduce a new model for rill erosion. We start with a network similar to that in the Discrete Web** and instantiate a dynamics which makes the process highly non-Markovian. The behavior of nodes in the streams is similar to the behavior of Polya urns with time-dependent input. In this paper we use a combination of rigorous arguments and simulation results.

Kemampuan koneksi dan berpikir kritis adalah bagian dari kemampuan yang harus dimiliki siswa agar bisa memecahkan masalah di dunia nyata. Namun ditemukan bahwa kemampuan-kemampuan ini masih rendah. Kemampuan-kemampuan ditingkatkan sejak usia Sekolah Dasar, melalui dituangkan dalam soal cerita. Agar solusi diberikan tepat, maka penyelesaian dilakukan menggunakan tahapan Polya. Sehingga penelitia...

Fast-growing technology and the development of IT services have yielded idea founding a new application stochastic processes their properties. We give connection between electronic process management relatively named Non-central Polya-Aeppli process. This is applied as counting in mathematical construction given model, it has been introduced management.

What is the nature of expertise? This paper posits an answer to that question in the domain of geometry problem-solving. We present a computer program called POLYA which makes use of explicit planning knowledge to solve geometry proof problems, integrating the processes of parsing the diagram and writing the proof.

Kemampuan pemecahan masalah merupakan kecakapan matematika yang wajib dikuasai siswa karena tujuan pembelajaran matematika. Penting bagi seorang guru untuk mengetahui sampai di mana tahap penyelesaian dapat dilakukan siswa. Penelitian ini bertujuan melihat kemampuan matematis SMP Kecamatan Bantan serta kesulitan ketika memecahkan masalah. Tes diberikan adalah soal berbasis Hasil tes dianalisis ...

En este artículo se caracteriza una perspectiva de la resolución problemas como aproximación didáctica. Particularmente identifican aquellos aspectos comunidad aprendizaje que favorecen el desarrollo un con entendimiento, a partir las contribuciones diversos matemáticos y educadores matemáticos, entre los encuentran George Polya, Paul Halmos, Jaques Hadamard, Alan Schoenfeld, James Hiebert Rich...

Mathematicians study shapes, structures and patterns. However, there are shapes, structures and patterns within the body and practice of mathematics that are not the direct objects of mathematical study. Rather, they are part of the explanation of how mathematical study is possible, and thus demand the attention of epistemologists and phenomenologists as well as mathematicians. Partial philosop...
