Abstract

Abstract: The research aims to know: 1) which learning model is better achievement LC 5E with scientific appraoach, PBL, or direct learning models : 2) the learning autonomy category giving a better achievement among the high, medium, and low level of learning autonomy; 3) the learning autonomy which yields a better achievement of each learning model ; and 4) learning model which yields a better achievement of each learning autonomy category. The type of the research is a quasi-experimental research. The research is carried out in Sukoharjo regency. The populations of research are all 10th students of in Sukoharjo regency in which  school based curriculum applied in the academic year of 2014-2015. The sampling technique uses Stratified Cluster Random Sampling. The data collecting techniques use documents, questionnaires, and tests. The data analysis technique uses two-way variant analysis with unequal cells. The research concludes that; 1) the LC 5E learning model with scientific approach gives a better achievement in mathematics learning; 2) the students with high learning autonomy get better mathematics scores. The indicator is the average  scores of students with high learning autonomy are better than those with low or medium level; 3) In each learning model, the students with high learning autonomy get  better achievements than those  with medium or low as well  learning autonomy in general,whereas in high learning autonomy category, the LC 5E learning with scientific approach shows a better math achievement than PBL; and 4) For the classification of learning autonomy between the high level and the medium one,  learning model  LC 5E with scientific approach shows better achievement mathematics learning than the one with PBL  or direct learning, whereas, the low learning autonomy has no different achivement LC 5E with scientific approach, PBL or the direct one.Keywords: Mathematics Learning Achievement, Learning Autonomy, Learning Model

Abstract. The aims of this research are to know: 1) which learning models between OEL learning model using scientific approach, PBL scientific approach, or direct learning, give better achievement in learning quadrangle, 2) what kind of creativity between high creativity, medium creativity, or low creativity give better achievement, 3) in each students’ creativity, which learning model gives better achievement in mathematics learning between OEL using scientific approach, PBL using scientific approach, or direct learning, and 4) in each learning model, which one gives better achievement in mathematics learning or mathematics learning achievement between the students who have high creativity, medium, or low. This research was a quasi-experimental study by using a 3 x 3 factorial design. The population of the research was the seventh grades of MTsN in Ngawi regency in the Academic Year of 2014/2015. The sample was taken by using stratified cluster random sampling. Consist consisting of 318 students: 108 students in first experiment, 102 students in second experiment, and 108 students in control class. This experimental used independent variables that were learning model and the students’ creativity, and dependent variable was achievement in mathematics learning or mathematics learning achievement. Moreover, the validity test of instruments (the mathematics test and questionnaire) was done by validator. Then, the reliability of test instrument used KR-20 formula, whereas, the reliability of questionnaire used Cronbach Alpha. The internal consistency test of questionnaire was done by using Product Moment Correlation of Karl Pearson. The prerequisite test consists of Normality Test done by Lilliefors and Homogeneity Test using Bartlett. Then, data was analyzed by using two-way ANOVA.The results of the research are: 1) the mathematics learning using OEL with scientific approach gives better achievement than using PBL with scientific approach or direct learning, and PBL with scientific approach gives better achievement than direct learning, 2) the students who have high, medium and low creativity have same/equally mathematics learning achievement, 3) each  creativity, the students who learn mathematics using OEL have better achievement than those who learnt mathematics using PBL and direct learning, while the students who learnt mathematics using PBL have better achievement than those who use direct learning, and 4) in each learning model, the students who have high, medium and low creativity have same/equally mathematics learning achievement.Keywords: Problem-Based Learning, Open-Ended Learning, Students’ Creativity.

Abstract

The regression model that can be used to model spatial data is Spatial Autoregressive (SAR) model. The level of accuracy of the estimated parameters of the SAR model can be improved, especially to provide better results and can reduce the error rate by resampling method. Resampling is done by adding noise (noise) to the data using Ensemble Learning (EL) with multiplicative noise. The research objective is to estimate the parameters of the SAR model using EL with multiplicative noise. In this research was also applied a spatial regression model of the ensemble non-hybrid multiplicative noise which has a lognormal distribution of cases on poverty data in East Java in 2016. The results showed that the estimated value of the non-hybrid spatial ensemble spatial regression model with multiplicative noise with a lognormal distribution was obtained from the average parameter estimation of 10 Spatial Error Model (SEM) resulting from resampling. The multiplicative noise used is generated from lognormal distributions with an average of one and a standard deviation of 0.433. The Root Mean Squared Error (RMSE) value generated by the non-hybrid spatial ensemble regression model with multiplicative noise with a lognormal distribution is 22.99.

Abstract

The blended learning was a learning model that combines offline and online learning. There are two types of blended learning models used in this research, namely the flipped classroom model and the station rotation model. In these models, the teacher would use WhatsApp as a media for online learning. The purpose of this research was to determine the effect of blended learning models on mathematical creative thinking skills and math anxiety of public junior high school students in Sukoharjo Regency, Central Java Province. The research method used was quasi-experimental by sampling using stratified cluster random sampling techniques. There were three schools selected as research samples, namely Mojolaban 1 Public Junior High School, Mojolaban 2 Junior High School, and Grogol 3 Public Junior High School. The data collection used a written test and questionnaires methods which were carried out after the treatment was given. The data analysis technique used a one-way multivariate analysis of variance. This research shows that the blended learning models were better than the direct learning model on mathematical creative thinking skills, but judging from the magnitude of math anxiety, the direct learning model was better than the station rotation learning model.

There  are  three  regions  of  rainfall  that  has  been  formed,  each  rainfall  regions has a variety of homogeneous and there is a correlation between rainfall stations. In  each  region  can  be determined  rainfall  prediction  model simultaneously.  The model  is  a  model  of  Vector Autoregressive  (VAR)  which  is  an extension  of  the autoregressive  model  (AR).  Based  on  this  research,  we  can  determine  the  VAR model by lag 1 or VAR (1) for each region. Region 1 (Anjatan and Sumurwatu), region  2  (Salamdarma  and  Gantar)  and  region  3  (Kedokan  Bunder  and Sudimampir), each of which has a Root Mean Square Error Prediction (RMSEP) of  3.93;  5:03;  4:48;  5.3;  2:18  and  3:53.  Correlation  value  of  observations  with predictions of rainfall respectively, 0.71; 0.62; 0:57; 0:59; 0.89, and 0.91.  Keywords: AR, VAR, RMSEP, correlation
