Abstract

The differences in individual’s personality create diversity in communication. This study is aimed to describe the students’ written mathematical communication patterns based on personality types. It is a qualitative descriptive study in X grade vocational high school students of SMK N Tengaran, Semarang Regency in 2019/2020. The data were obtained by documenting the results of students’ mathematical communication tests and interviews. The research findings show that there is no unique pattern for each personality type in the mathematical communication patterns associated with sequence of working on questions. However, in mathematical communication patterns that are related to the type of error performed, the Introvert - Neurotic personality type makes the most types of errors in using incorrect variables and calculation errors.

Abstract

This study aims to describe students' problem-solving abilities by considering their curiosities. The subjects in this study are determined based on the analysis of the results of the Curiosity Inventory in class VIIIA students of SMP N 1 Bandungan, Semarang Regency. Students are grouped into two types, namely the type of Epistemic Curiosity (EC) and the type of Perceptual Curiosity (PC). The EC group are taken by two students, namely a weak (Lemah) EC (ECL) and a strong (Kuat) EC (ECK), as well as the PC group taken by two students, namely a weak PC (PCL) and a strong PC (PCK). This research is a mixed method research with a sequential explanatory design. The data collection techniques use questionnaires, tests and interviews. The effectiveness is analyzed based on (1) the average similarity test; (2) completeness test and average difference test. Based on data analysis, the results of tests and interviews show that the ECL type students are able to understand problems, plan solutions and carry out the completion plans, but are unable to check again. ECK type students are able to understand the problem until it checks again properly. The PCL type students are able to understand the problem but are less able to plan solutions and carry out the completion plan and are unable to check again. The PCK type students are able to understand problems, plan completion plans and carry out completion plans but are less able to check again.

Abstract

Learning with a teacher-centered model had not been able to optimize students’ higher-order thinking ability. It made the students’ metacognition were not maximum especially dealing with the mathematical representation ability. This research aimed to describe the mathematics representation ability based on the metacognitive categories. This research applied a combination method of sequential explanatory with regression test for the quantitative data. The results showed the metacognition influenced mathematics representation ability. Students with reflective use categories could identify and analyze the questions properly. They could also evaluate the answers although some of them did not write the questions into correct mathematics sentences. Students with strategic use categories could identify and analyze the questions properly but they did not evaluate their answers. Students with aware use could identify but they were a lack in analyzing and evaluating. Then, students with the tacit use category were not found. Teachers should direct the students with more development and counseling in a personal manner to overcome the gaps.
