Atensi Siswa Dalam Menyelesaikan Masalah Fungsi
No full textThis study aims to describe the students' attention processes in solving functional problems. This research is a qualitative descriptive study, with subjects of 2 students taken from 8 students of secondary school. The results show that the students' attention process in solving functional problems was based on attentional characteristics, namely when students who answered correctly in solving questions and interview process, before and after reflection had complete cognitive attention structures. While students who answer incorrectly in solving problems have incomplete attention to cognitive structures, characterized by a lack of concentration in seeing the relationship between one mathematical object and another mathematical object. Attention characteristics in this study begin with recalling previous information and responding or giving feedback to problems by linking previous information with existing problems. Next analyze by breaking down information into smaller parts and easy to understand. The next step looks at the relationship between the decomposition process to get ways that can be used in the settlement process to obtain the final results that are part of decision making.Penelitian ini bertujuan untuk mendeksripsikan proses atensi siswa dalam menyelesaikan masalah fungsi.

Analisis Kesalahan Siswa SMP pada Materi Perbandingan berdasarkan Perspektif Gender dan Analisis Kesalahan Newman.
No full textThis research was conducted to find out how the gender perspective affects the mistakes made by students in the ratio and proportion questions. Mindset’s differences between male and female will affect how they solve problems and it will also affect their mathematics learning outcomes. Errors made by students were analyzed using the Newman error analysis indicator. Error analysis indicators used are reading errors, misunderstanding errors, transformation errors, process errors, and error writing answers (encoding). This research uses descriptive qualitative research method. This research was conducted at SMPN 2 Cimahi. The instruments in this study were test and non-test questions. It can be concluded from this research that there are differences between male and female students when working on ratio and proportion concept questions based on the mistakes they’ve made. The most common mistakes made by male students are mistakes in the process of writing answers. This error occurs because they do not write down the complete answer details, it’s because male tend to be simpler in solving problems. The most common mistake made by female is an error in understanding. It’s because female tend to use logic-less when understanding the mathematical problems presented in the questions
AN INTRODUCTION TO THE RASCH MEASUREMENT MODEL: A CASE OF MATHEMATICS EDUCATION STUDENTS COMPREHENSIVE TEST
Full text linkMathematics assessments should be designed for all students, regardless of their background or gender. Rasch analysis, developed based on Item Response Theory (IRT), is one of the primary tools to analyse the inclusiveness of mathematics assessment. However, the mathematics test development has been dominated by Classical Test Theory (CTT). This study is a preliminary study to evaluate the mathematics comprehensive test. This study aims to demonstrate the use of Rasch analysis by assessing the appropriateness of the mathematics comprehensive test to measure students' mathematical understanding. Data were collected from one cycle of mathematics comprehensive test involving 48 undergraduate students of mathematics education department. Rasch analysis was conducted using ACER Conquest 4 software to assess the item difficulty and differential item functioning (DIF). The findings show that the item related to geometry is the easiest question for students, while item concerning calculus as the hardest question. The test is viable to measure students’ mathematical understanding as it shows no evidence of Differential Item Functioning (DIF). Gender has been drawn for each of the test items. The assessment showed that the test was inclusive. More application of Rasch analysis should be conducted to create a thorough and robust mathematics assessment
