Abstract

This study aims to determine the mathematical habits of students and students' mathematical literacy skills in solving 4c ability-oriented math problems. This research was a descriptive research with a qualitative approach. Data collection techniques were questionnaires, tests, and interviews. The sample of this research was eight grade students of MTs Negeri 1 Pacitan in academic year of 2021/2022. The total samples were 32 students by using purposive sampling technique. The instrument that used in this research were a mathematical habits of mind's questionnaire and 4c ability-oriented mathematical literacy test. The data analysis technique used the Miles and Huberman model. The results of this study indicate that students of MTs Negeri 1 Pacitan produce data, namely 31% of students have high mathematical habits of mind, 31% of students have average mathematical habits of mind and 38% of students have low mathematical habits of mind, then the total number of participants in the low category was higher than in the high and medium categories. Based on the analysis of the results of the answers and interviews, it can be concluded that one sentence has not accomplished by the students were mathematical literacy to interpret the situation mathematically, the use of variables, and symbols, mathematical concepts, facts, procedures, and the reason in answering questions correctly. At low Mathematical habits of mind students were able to use communication skills and collaboration skills. Sstudents with average and high mathematical habits of mind were able to use critical thinking skills, mathematical communication skills and collaboration skills

Abstract

This study aims to explore and analyze the implementation of e-flipbook learning media on vector material in 10th-grade students at SMK Negeri 1 Pacitan. The research method used is qualitative with a case study approach. Data were collected through observation, interviews, and documentation. The findings indicate that the use of e-flipbook as a learning medium can enhance students' understanding of vector concepts, motivate them in the learning process, and provide variety in teaching methods that are more interactive and engaging. However, there are some technical challenges that need to be addressed, such as limited access to technology and the digital media skills of teachers and students. Overall, the implementation of e-flipbook has great potential to support an effective and efficient learning process.

Abstract

The scoring of multiple choice test items with the conventional model causes disparities in the interpretation of the scoring results. This causes unfair scoring, because the scoring does not pay attention to the characteristics of the items attached to the test. To overcome this problem, the purpose of writing this article is to apply the IRT model to make scoring more fair, so that multiple choice tests are able to provide a more precise and objective interpretation of scores. The multiple choice test used in this study is a math test on Algebra content of 15 items. The test was piloted on 65 grade 8 junior high school students. This data was used to calibrate test items using IRT. Model fit is determined by the M2 method. The instrument is compatible with the Rasch, 2PL and 3PL models, but only the Rasch and 2PL models used in this article. The number of items that fit in both models is the same as the number of multiple choice test items. Furthermore, the item parameters are used as the basis for scoring. The comparison results show that the IRT model is able to provide a more objective and precise scoring, based on the characteristics possessed by the test items. Model 2 PL is able to provide the most fair scoring than the Rasch and conventional models. The characteristics of the discriminant parameters in the 2PL model make it possible to distinguish students' abilities. especially for students who have the same number of correct answers, but the pattern of answers is different

Abstract

The complexity of the IRT analysis makes it difficult to perform manually, therefore requiring easy-to-use software. While many software options exist for IRT analysis, the high cost of paid software can make it inaccessible for many students and lecturers in Indonesia. While the mirt package provides a complete, free option for IRT analysis, it requires proficiency in the R programming language to use. This study aims to develop an R package for IRT analysis, equipped with a user-friendly interface based on the mirt package, designed to be easy to use for beginners in IRT analysis. The System Development Life Cycle (SDLC) model is used for development, which includes five stages: Planning, Analysis, Design, Implementation, and System. The resulting package is named irtawsi and includes functionality comparable to paid software. This package can calibrate both test and non-test instruments using various IRT models, such as the Rasch, 2PL, 3PL, 4PL, GRM, PCM, and GPCM model. The irtawsi package functionality includes (1) an easy-to-use user interface, (2) automatic interpretation of analysis results, (3) a guide for IRT analysis, (4) recommendations when assumptions are not met, (5) an HTML report format for analysis results,(6) support for two languages (Indonesian and English), (7) it’s free, and (8) can be installed on Windows, macOS, and Linux operating systems.

Abstract

Mathematical literacy is one of the components that is of concern to the Minimum Competency Assessment (AKM). This policy is an effort by the Ministry of Education and Culture to overcome the low literacy skills of students, and the faktors that cause it. Multistage Adaptive Test (MSAT) is used as an assessment method in AKM. The MSAT was developed with the IRT concept. The purpose of this article is to apply Item Respons Theory (IRT) to calibrate mathematical literacy instrumens and utilize the calibration result item parameters to estimate scores for mathematical literacy skills. Many items in the instrumen used are 15 multiple choice items. Respondents were used as many as 66 grade 8 junior high school students. After going through the construct validation process using Confirmatory Factor Analysis (CFA), 2 items did not meet, because they had a low loading factor, and 13 items were used for the calibration process. The grain calibration and scoring processes were carried out using the R package Mirt program. The calibration results show that the instrument matches the Rasch model. All assumptions of unidimensional IRT are proven to be met, so there is no violation in estimating item parameters. The item parameter is the level of difficulty where there is one item that does not fit, namely item 3. The intersection of the information function and the standard error shows that the instrument will provide accurate information if it is used by students with abilities of -2.965 to 1.085. The resulting item parameters can be used to estimate the algebra content math literacy score.

Abstract

This research aims to determine the influence of independent learning and structure sense abilities on mathematical connection abilities in students at SMK Negeri 2 Pacitan. The research method used is a quantitative approach with an ex-post facto type of research. Data was collected through questionnaires and test instruments. The data analysis used is simple linear regression analysis and simple linear analysis. The results of the research show that independent learning has no effect on students' mathematical connection abilities, while structure sense abilities have a significant effect on students' mathematical connection abilities. However, together independent learning and structure sense abilities influence students' mathematical connection abilities.

Abstract

The research aims to determine the characteristics of mathematical literacy instruments in geometry and measurement content reviewed from the perspective of item response theory. The type of research used is quantitative description. The study subjects were 235 students in grade VIII of junior high school in Pacitan Regency, with details of 108 male students and 127 female students. Item analysis was carried out using IRT. The calculation uses the R program with the help of the mirt package. The study results showed that the mathematics literacy instruments, geometry content, and measurement characteristics were by the 1 PL model. Furthermore, from 8 question items, 7 items were fit and 1 item was not fit. One item that is not fit is item number 7, so the item must be removed. Mathematical literacy instruments in geometry and measurement content consisted of 14.29% of medium category questions and 85.71% of difficult category questions. The instrument is suitable for measuring students who have abilities ranging from -0.78 to 2.85.
