Abstract

Module constitutes one of material teach applicable to increase learning quality. Largely student most constraint studies mathematics because terminological they that mathematics abstraction. Berdasakan it is developed module which concern material with student real life. One of approaching in mathematics that gets bearing with student real life is REACT'S approaching (Relating, Experiencing, Applying, Cooperating, Transferring). To the effect this research is develop module that valid and paktis on Line and Line material with REACT'S approaching. This observational type constitute development research with model developmental ADDIE who covers five subject steps, which is analysis, design, development, implementation, and evaluation. Instrument that is utilized is sheet validate material pro, sheet validates media pro, and student response questionnaire. Subjek is this research is SMK'S student Ile Boleng's Country brazes X. Kevalidan module reaches score percentage average 77%. Seen from practicability aspect, practical stated module with score percentage average 95% by pretty good categories.

Abstract

Creative thinking in classroom learning needs to be optimized so that students have more skills in dealing with and solving problems that arise, especially those related to mathematics. The purpose of this study was to describe the ability of students to think creatively when solving pythagorean theorems in learning with the learning model of Submission and Problem Solving (JUCAMA). This research method is qualitative research. The subjects of this study were 6 eighth grade students of SMP Negeri 2 Laboya Barat, which consisted of 2 students with high mathematics abilities, 2 students with moderate mathematics abilities, and 2 students with low math abilities. Data taken through tests, interviews and documentation. Then the data is analyzed and described. Analysis of creative thinking tests refers to three indicators of creative thinking namely fluency, flexibility, and novelty. The results showed that students who have high math skills can fulfill three indicators of creative thinking based on Siswono theory because they can show fluency, flexibility, and renewal. Students with mathematical abilities are able to fulfill two indicators and cannot fulfill happiness. Meanwhile, students with low mathematical abilities do not fulfill three indicators based on Siswono theory because they are not fluent, not flexible and not renewable in solving the problem.

Abstract

Mathematics learning achievement is the learning outcome/ability achieved by students during and after completing mathematics lessons where the results are expressed in the form of numbers or other symbols. Learning achievement is influenced by several factors including family economic background and parental support. This research is quantitative research, the study population was all VII grade students of Boawae 1 Junior High School totaling 101 students. Sampling using simple random sampling, where researchers about 24% of the population to be selected as samples, so that the study sample amounted to 24 students. The stages of this research are data collection using a questionnaire then analyzing the data using Pearson product moment correlation. The data collection process uses questionnaire techniques. Research data were analyzed using Pearson product moment correlation. Based on this study, it can be concluded that There is an insignificant relationship between the family's economic background on the mathematics learning achievement because the value of rcount is 0.242 smaller rtable at a significant level of 5% that is 0.404 and there is a relationship between parental support for mathematics learning achievement because the rcount of 0.747 is greater than rtable at a significant level of 5% which is 0.404 and there is a jointrelationship between the family's economic background and parental support for mathematics learning achievement because the Fcount value of 14.701 is greater than Ftable at the 5% significance level of 3.47.

Abstract

Teori estimasi/penaksiran memiliki dua pendekatan yaitupendekatan statistika klasik dan pendekatan statistika global(Bayesian). Statistika klasik adalah statistika dimana tatacarpengambilan keputusannya didasarkan hanya pada data sampel yang diambil dari populasi. Sedangkan statistika Bayesian dalampengambilan keputusannya didasarkan pada informasi baru dari data yang diamati (sampel) dan pengetahuan sebelumnya. Padtulisan ini Analisis Regresi Cox akan diambil sebagai contoh penaksiran parameter dengan pendekatan statistika klasik danAnalisis Survival Bayesian sebagai contoh pendekatan statistikglobal (Bayesian). Estimasi parameter Survival Bayesiamenggunakan algoritma MCMC karena model yang komplek/rumitsehingga sulit diselesaikan sedangkan model Regresi Coxmenggunakan metode partial likelihood. Hasil yangdiperoleh dari estimasi parameter tersebut tidak close form sehingga perldilakukan dengan metode iterasi Newton-Raphson.
