Abstract

Abstract. The objective of this research was to investigate the effect of the learning models on achievement viewed from creative thinking abilities (CTA) of the students. The learning models compared were PBL, TGT and direct instruction (DI). The type of the research was quasi-experimental research with 3x3 factorial design. The population of this research was the students in grade X senior high school in Purbalingga on academic year of 2014/2015. The size of the sample was 277 students, which was taken by using stratified cluster random sampling technique. The instruments used for data collection were creative thinking test and achievement test. The hypothesis test used unbalanced two ways analysis of variance. The results of the research were as follows. (1) PBL gave better achievement than TGT and DI. TGT gave better achievement than DI. (2) The students with high and medium CTA had better achievement than the students with low CTA. The students with medium CTA had better achievement than the students with low CTA. (3) In PBL, the students with high CTA had better achievement than medium and low CTA, the students with medium and low had the same achievement. In TGT, the students with high and medium CTA had the same achievement, the students with high CTA had better achievement than low CTA, the students with medium and low CTA had the same achievement. In DI, the students with high, medium and low CTA had the same achievement. (4) At the students with high CTA, PBL and TGT gave the same achievement. PBL and TGT gave better achievement than DI. At the students with medium CTA, PBL and TGT gave the same achievement, PBL gave better achievement than DI, TGT and DI gave the same achievement. The students with low CTA, PBL, TGT and DI gave the same achievement.Keywords: Problem Based Learning, Teams Games Tournamnet, Direct Instruction, Creative Thinking Abilities , Achievement.

Abstract

Abstract — This research is the development of the Microsoft Excel VBA application to perform regression analysis between weather parameters in terms of data centering measures (PAMER11). The combination of parameters and data centering measures obtained 55 parameters that can be combined into 1,677,255,139,725 annual regression analysis outputs. The case study used in this study only calculates air humidity with temperature and air pressure observation variables, then the analysis results are compared with the results of the Excel Toolpak analysis data with the Anova. The development of this application method is carried out in 4 stages, namely: define, design, develop, adn dissemination. The defined stage includes analysis of the needs of researchers in the BMKG field, analysis coverage of the needs of BMKG in the form of regression analysis. The design stage includes format selection, application program selection, and initial design (prototype 1). The development stage includes validation (prototype 2) obtained a programming aspect value of 4.1325 valid criteria, comparison of Anova results from the output of the PAMER11 application and analysis of the Excel toolpak, the f-value is with a p-value of 99% which results in the two calculations are significantly equal, for the display aspect get a value of 4,8175 valid criteria, limited and field product trials (prototype 3), where a limited trial was carried out on all faculty lecturers getting a score of 4.2440 very good criteria. Field trials conducted on the BMKG Cilacap got a score of 4.8333 very good criteria and data analysis at each stage of development has been improved towards the application program. Keywords — Development; Microsoft Excel; Visual Basic for Application (VBA); Regression Analysis; Weather Parameters
