Abstract

This research has aims to determine the effectiveness of learning model Think-Talk-Write (TTW) and determine whether the learning TTW modelis more effective than conventional learning to improve student mathematical communication. The research is a quasi experimental research. The populationin this research were all students ofthe second semester in Mathematics Education department. They are divided into four parallel classes. Samples were IIA2 class as the control class and the IIA1 class as a class experiment in Number Theory lesson. The instrument in this researcsh was test of mathematical communication. The analysies of data use SPSS 16, the proportion test of one population, and t test. The hypotesis tests use the proportion test of one population and t test. Based on the results of this research were concluded that : (1) The mathematical learning by learning model Think-Talk-Write is effective to improve the mathematical communication students. It can be proved fromthe results of proportion testonan experimental class of mathematical communication valueis 1.87 > z table with a significance level 5%. Z table is 1.64. (2)The learning model Think-Talk-Write more effective than conventional approaches. It can be proved from the results of t test. The value of mathematical communicationis 2.07 >t table with a significance level 5%. t table is 1.67.

Abstract

This paper will discuss the randomness and normality tests of the data collected by splittingthe interval [a,b] into several subintervals [xi,xi+1] (i = 0, ..., n-1) with x0 = a and xn = b for verifyingthat the optimization problem constitutes a Wiener process. Furthermore, the data can be used toevaluate the efficiency of probabilistic algorithm as proposed in this paper in determining the bestsubinterval to be explored by Newton’s method for searching the optimal point of global optimizationproblem.

Abstract

Anak jalanan adalah sekelompok anak-anak yang menghabiskan sebagianbesar waktu mereka di jalan. Mereka menjual koran, bernyanyi atau hanya memintabelas kasihan untuk memenuhi kebutuhan mereka. Pendampingan belajar yangdilakukan berupa pendampingan anak jalanan dalam belajar matematika. Tujuandari kegiatan ini adalah untuk meningkatkan motivasi belajar, keterampilanmatematika bagi anak-anak jalanan , dan penyediaan media pembelajaran bagikelompok belajar di bantaran sungai Winongo. Peserta pendampingan terdiri dari 40anak-anak, yang berusia sekitar 7-9 tahun. Kegiatan dilaksanakan mulai bulan Juli2016 sampai Oktober 2016. Hasil kegiatan ini: 1) Pendampingan belajar dengan carayang menyenangkan dapat meningkatkan motivasi belajar anak matematika jalanandi pinggiran Winongo; 2) Pendampingan belajar dengan cara yang menyenangkandapat meningkatkan ketrampilan matematika anak jalanan di pinggiran Winongo; 3)Pengenalan matematika dasar untuk anak-anak membutuhkan bahan ajar dan mediayang menarik bagi anak-anak belajar.
