Abstract

The objective of this study is to analyze the difficulty of representation ability Mathematical extrovert students in class VII-D in solving math problems on algebraic material, as well as knowing the factors that cause difficulties experienced by students in meet the indicators of mathematical representation ability. The ability of mathematical representations is measured based on Its aspects include visual representation aspects, expression representation aspects mathematics, and aspects of the representation of words or written text. This is qualitative research using a descriptive approach. This is carried out at SMP Negeri 22 Jambi with 4 students from class VII-D. The results showed that SE1, SE2, SE3 and SE4 are students with extrovert personalities do not have difficulty in the visual aspect. On aspects of representation of mathematical equations or expressions of Students SE1, SE3, and SE4 having difficulty making mathematical models or equations. On that aspect word or written text students SE2, SE3, and SE4 have difficulty when determine what steps will be taken to solve the problem mathematical. Factors causing difficulties in the mathematical representation ability are on visual aspects, representational aspects of mathematical expressions, and aspects of word representation or written text is a non-cognitive learning factor

Abstract

This study was conducted at SMP Negeri 9 Jambi City to determine the effect of the Problem-based Learning (PBL) model on mathematical literacy skills in the Pythagorean Theorem material. The quasi-experimental design was used with a non-equivalent pretest and posttest control group design. The researchers collected the mathematical literacy ability data using a description test instrument. Furthermore, the visual-verbal ability data was collected using a visual-verbal ability questionnaire. This research was conducted on the seventh-grade students, with 69 students divided into two classes (experimental and control classes). A random sampling technique determined the sample. Based on the two-way ANOVA test, applying the Problem-based Learning (PBL) model on students' mathematical literacy skills was an effect. There was an effect of visual-verbal ability on literacy skills.
