Abstract

The research aims to determine the effectiveness of cooperative learning model type Think Talk Write (TTW) and type Think Pair Share (TPS) toward the mathematic communication skill students of grade 8th in MTs N Godean. This type of research is comparative descriptive which aplies Pretest Posttest Control Group Design. An instrument used in this study there are two kinds of the instruments learning and instruments data collection. An instrument consisting of learning implementation lesson plans and sheets of student activity, instruments gather data consists of broad observation, questionnaire, a test (pretest and posttest) and documentation. Analysis of data on research use t test some help software Ms. Excel 2010 and SPSS 20. The results of research pretest and posttest show that experiment class with cooperative model type Think Talk Write (TTW) and control class with cooperative model type Think Pair Share (TPS) normal distribution, both classes are homogenous and both classes have the same initial capability. The cooperative learning model type Think Talk Write (TTW) is same effective with cooperative learning model type Think Pair Share (TPS) toward the mathematic communication skill students. The level of effectiveness cooperative learning model type Think Talk Write (TTW) is 0,30 with medium category and the level of effectiveness cooperative learning model type Think Pair Share (TPS) is 0,28 with low category. Cooperative learning model type Think Talk Write (TTW) is same effective with cooperative learning model type Think Pair Share (TPS) because the students are individually active role in group discussions and there is the same syntax for these two models namely stage think.Keyword: Cooperative learning model type Think Talk Write (TTW), cooperative learning model type Think Pair Share (TPS), mathematic communication skill students.

Abstract

AbstractThe purpose of this research is to analyze the competence of teachers as part of the teachers’ pedagogical content knowledge in applying scientific approach in Mathematics PLPG (in-service teacher education and professional training) program rayon 138 Yogyakarta, Indonesia, in 2014. The research method used is descriptive with quantitative approach. The subjects of the study consisted of 23 mathematics teachers including mathematics teachers of junior high school, high school and vocational school from Kebumen, Purworejo, and Magelang. Data was collected by filling in a questionnaire at the beginning and end of the training, observing microteaching activities, and documenting the learning material arranged by PLPG participants. Based on the analysis, it can be concluded that PLPG especially PLPG rayon 138 Yogyakarta, Indonesia, in 2014 gives benefits for the development of teachers’ PCK, especially in terms of teachers’ competence in applying scientific approach. Based on the analysis of learning materials arranged by the teachers and analysis of learning videos, it is known that the majority of the teachers have been able to construct a learning material using scientific approach and implement it properly.  Keywords: teacher’s competence, pedagogical content knowledge, scientific approach, PLPG

Abstract

The research objective is to produce a module by using a Macromedia Flash both content and presentation material, which is able to contribute comprehension of concept of students in the subject of development of instructional media. This refers to the development of research Thiagarajan there are four phases, definition (define), design (design), development (develop), and dissemination (dessiminate). The development phase of module of the 4-D (Four D Device) Thiagarajan Semmel and Semmel to design a module on the course development of instructional media. The process of developing this module starts from the stage of defining or analysis. The process of designing a module that was developed based on information obtained from the analysis phase of the open-ended, students, materials, tasks that support and then do the design stage or the design. And then the last stage is the stage of development. Development of modules on the course development of instructional media developed proven valid content with the results of assessment for an average of 85.5%. The results are based on votes of validator to provides good value and can be used with minimal revision. Keywords: development, module, macromedia flash

Abstract

A stock returns data are one of type time series data who has a high volatility and different variance in every point of time. Such data are volatile, seting up a pattern of asymmetrical, having a nonstationary model, and that does not have a constant residual variance (heteroscedasticity). A time series ARCH and GARCH model can explain the heterocedasticity of data, but they are not always able to fully capture the asymmetric property of high frequency. Integrated Generalized Autoregresive Heteroskedascticity (IGARCH) model overcome GARCH weaknesses in capturing unit root. Furthermore IGARCH models were used to estimate the value of VaR as the maximum loss that will be obtained during a certain period at a certain confidence level. The aim of this study was to determine the best forecasting model of Jakarta Composite Index (JSI). The model had used in this study are ARCH, GARCH, and IGARCH. From the case studies were carried out, the result of forecasting volatility of stock index by using IGARCH(1,1) obtained log likelihood values that 3857,979 to the information criteria AIC = -6,3180; BIC = -6,3013; SIC = -6,3180; dan HQIC = -6,3117. Value of VaR movement of the JCI if it becomes greater the investment is Rp.500,000,000.00 with a confidence level of 95% on the date of July 2, 2015 using a model IGARCH (1,1) is Rp7.166.315,00.

Abstract

The aims of this research is to improve students’ strategic mathematic ability. This research was conducted according to Class VII A Mathematic teacher’s explanation that students unable to find the mathematic relation from question and developing an effective solving method. It was supported by the Class VII A students’ mid test result, students found it difficult to solve a problem because 85% of 35 students unable to solve it. That means 30 students of Class VII A do not have the ability in strategic mathematic competence. This research is a Class Action Research (CAR) that conducted collaboratively. The subject of this research is Class VII students of SMP N 11 Yogyakarta that consists of 35 students. The object of this research is mathematics learning using Metaphorical Thinking approach to improve students’ mathematic strategic competence ability. This research consist of 2 cycles, there are 3 meetings for every cycle. Research data obtained from learning observation sheet, interview result, field note, written test and documentation. The result of this research show that students’ strategic mathematic competence is improving according to first and second cycle last test’s score. Average score pre-research which taken from mid semester test of Class VII A students is 66,22 with students’ KKM achievement percentage is 25,71%, while in the end of first cycle the average strategic mathematic competence ability test result improved into 74,14 with students’ KKM achievement percentage is 57,14%. Students’ strategic mathematic ability average score achieve the KKM on the second cycle with average score 84,74. The percentage of students’ which achieve KKM on second cycle is 77,14%. Keyword: Metaphorical Thinking, Strategic Mathematic Competence
