Abstract

Mathematical representation is the ability to express ideas or definitions raised by the students when solving problems. At now, most students have difficulties in the ability of mathematical representation. The difficulty of this mathematical representation needs to be analyze the causes, including analysis based on gender differences. This type of research is a qualitative study which aims to systematically describe the ability of mathematical representation based on gender differences. The subjects of the study was grade IX students at SMP Negeri 4 in Natar, South Lampung. Research subjects numbered 31 people, consisti of 16 boys and 15 girls. Data was collected through tests and observations, and data were analyze descriptively based on 3 indicator levels, namely visual representations, mathematical expressions or similarty, and written words or texts. The results showed that there were differences in representation when viewed regarding gender, where girls make more representation than boys.

Abstract

In general, solving the two-fold integral of trigonometric functions is not easy to do analytically. Therefore, we need a numerical method to get the solution. Numerical methods can only provide solutions that approach true value. Thus, a numerical solution is also called a close solution. However, we can determine the difference between the two (errors) as small as possible. Numerical settlement is done by consecutive estimates (iteration method). The numerical method used in this study is the Romberg method. Romberg's integration method is based on Richardson's extrapolation expansion, so that there is a calculation of the integration of functions in two estimating ways I (h1) and I (h2) resulting in an error order on the result of the completion increasing by two, so it needs to be reviewed briefly about how the accuracy of the method. The results of this study indicate that the level of accuracy of the Romberg method to the analytical method (exact) will give the same value, after being used in several simulations.

Abstract

Spatial material was material that was very useful in everyday life. Students often had difficulty in imagining spatial objects. Students would had no difficulty in imagining spatial objects if they had good spatial ability. Resilience was needed to learn spatial ability. The purpose of this study was to determine whether there was a relationship between resilience and spatial ability and how many the coefficient correlation was, and to find out dominant indicators of resilience so that there was a relationship between resilience and spatial ability in students in the upper, middle, and lower groups. This research was a qualitative-quantitative mixed research. The research instrument was used a test of spatial ability in distance and resilience scale material. The data analysis technique was used the correlation test and data triangulation method. The conclusions of this study were (1) there was a relationship between resilience and spatial ability of 56%, (2) indicators of resilience 'willing to socialize, easy to provide assistance, discuss with peers, and adapt to the environment' were dominant in the upper, middle, and lower groups , resilience indicator ‘use failure experiences to build self-motivation’ was dominant in the upper group, resilience indicators ‘show curiosity, reflect, examine, utilize a variety of dominant sources in the upper group, indicators of resilience perseverance, confidence, work hard, not easy to give up facing problems, failures and uncertainties' were dominant in the lower classes.

Abstract

Problem solving mathematics error in a matter of story on ratio material worth and turn around values still often occur, so we need a remedial program to minimize these errors. For this reason, this study aims to determine the types of errors, remedial program steps and types of errors after the remedial program. This research is a qualitative descriptive study with the data collection method uses tests, interviews, and personal documents. The study was conducted at eighth grade of SMP Pangudi Luhur 1 Yogyakarta. This study applies a layered validation strategy in the form of triangulation techniques, Focus Group Discussion (FGD) and the involvement of resource persons and experts. The results showed that the dominant error in the form of an error did not understand the command problem with a percentage of 43%, the error shown if every step taken by students was correct but the final result given was not a solution done with a percentage of 80% and a calculation error with a percentage of 20%. After the results are obtained remediation efforts are made. Based on the remediation results that have been made, there is a decrease in 2 categories of dominant student errors, namely mistakes not understanding the question command to a percentage of 31%, errors that are shown if each step taken by students is correct but the end result given is not a completion done to 60%. Thus, the remediation program makes fewer types of mistakes made by students than before remediation.
