Abstract

In mathematics, students usually experience errors in solving word problems. Previous studies found that students’ skills in solving word problems were not good enough. Therefore, exploring students’ errors to be a consideration in designing efforts to minimize these errors is necessary. This study aimed to describe the errors made by students in solving word problems in exponential numbers based on Newman’s theory. Based on Newman’s view, there are five stages of student error: reading errors, comprehension errors, transformation errors, process skill errors, and encoding errors. This research is a descriptive qualitative study involving grade nine with two students in each category, namely high, medium, and low levels of mathematics ability. The data collection was conducted through documentation and interview. The study’s data analysis involved data reduction, display, and conclusion drawing. Based on the data analysis, it could be concluded that: 1) students with high mathematical ability still committed errors in the transformation, process skill, and encoding stages, 2) students with moderate mathematical ability were still experiencing errors in the transformation, process skill, and encoding stages, but one of the subjects also made errors at the reading and comprehension stages, 3) students with the low mathematical ability experienced quite a lot of errors in solving the word problems, namely at the comprehension, transformation, process skill, and encoding stages but one of the subjects also made errors at the reading stage. These findings could be used as consideration in planning teaching and learning activities to minimize the occurrence of similar errors in students with various levels of mathematical ability.

Abstract

Congestion is one of the few issues that has always been the center of attention at crossroads. One of them is at the intersection of Tuanku Tambusai, Nangka and Soekarno Hatta road. This congestion can be reduced by optimizing the duration of pauses at road intersections and collecting a compatible traffic flow when a red light occurs. The two traffic flows are said to be compatible if the two flows are running together without anyone crashing. A compatible graph is a graph that has two sets in which the object to be arranged is indicated by its points, and the corresponding pair of objects is indicated by its sides. This study obtained the optimal pause duration, which assumes a left turn following a red light for 75 seconds, by applying a compatible graph. Furthermore, the optimal duration of the pause assumes that the left turn does not follow the red light for 45 seconds. The pause duration is smaller than the duration now used on Soekarno Hatta Road, which is 115 seconds, using the assumption of following the red light to turn left. So obtained, the duration of the pause is much more optimal when compared to the duration of the pause used on the current Soekarno Hatta road

Abstract

Research in both ICT and RME is expanding at a breakneck pace. The growth of research in engineering can be tracked by one type of analysis known as bibliometric analysis. This analysis can be used to identify the number of scholarly publications on ICT and RME. This study is of a quantitative and descriptive nature. Researchers are interested in examining the development of ICT and RME, as well as the distribution pattern of publications in Scopus, which is based on research affiliations, research themes, and scientific journals. For the goals of data analysis, reduction, visualization, and mapping, respectively, Bibliometrix R-tool and BiblioShiny were utilized throughout the course of this research. Scopus bibliometric study finds that between the years 1999 and 2022, there was a shift in the number of research articles that could be located in the Scopus online database that were associated with ICT and RME. The year 2020 was the year that this publication - Journal on Education and Information Technologies - reached its zenith. In terms of the quantity of documents generated, research in the fields of ICT  is dominated by writers from the Czech Republic and the Netherlands.

Abstract

This study aims to describe the cognitive processes and knowledge dimensions that are measured on exam questions for junior high school mathematics in the Subrayon 05 Semarang Regency for the 2021/2022 academic year. This study uses a qualitative approach with content analysis techniques. Data collection is carried out through documentation. For further analysis of the contents of the data in the form of school exam questions. The research instrument includes a question review guide that is determined based on the dimensions of cognitive processes and the dimensions of knowledge. The results showed that the dimensions of cognitive processes and the dimensions of students' knowledge as measured through school exam questions for Mathematics subjects in Sub-Rayon 05 Semarang Regency ranged from understanding facts to creating which procedures; on questions that measure understanding facts, students are asked to classify facts in the form of notation, on questions that measure understanding of concepts, students are asked to classify related to certain mathematical concepts; on questions that measure applying concepts, students are asked to use or implement certain mathematical concepts in order to solve problems; on questions that measure applying procedures, students are asked to use or carry out certain mathematical procedures in order to solve problems; In questions that measure the ability to create procedures, students are asked to generate/hypothesizing specific skills and algorithms.

Abstract

This article describes the instruments that can measure students' higher-order thinking skills in learning mathematics for low, medium, and high difficulty levels. This study aims to estimate the validity and determine the reliability of the higher-order thinking test assessment instrument in Mathematics learning based on the Rasch model. The research was conducted through a quantitative descriptive approach in two SMP Negeri 1 Gebang, which had 100 respondents. The research development model used is the ADDIE model. This article describes the stages of development. The instrument used is a high-level mathematical thinking test assessment instrument which contains 20 questions and expert validation observation sheets. Mathematical higher-order thinking test questions were presented to three material experts. The validity used is content validity and construct validity. Reliability was tested through the Rasch model approach. The results showed that the HOTS assessment instrument in the form of HOTS test questions consisting of 20 items of description from the material, construction, and linguistic aspects and the appearance was declared to be constructively valid and suitable for use. The validity results can be seen and analyzed with the Winsteps program in the Out fit order table to see the suitability of items that function in the normal category to measure student misconceptions. The results showed the content validity through the Rasch model approach using Winstep software, where the peak of the graph approached the value 0, the item reliability value was 0.88, the item separation was 1.16, and the response separation was 2.65. The 90% of test questions with moderate criteria

Abstract

The students' relational understanding by applying blended learning is described in this study. The research method is descriptive quantitative that was performed by pre-experimental with a one-shot case study design. This study involves 33 class VIII students in one of the Karawang State Junior High Schools, which was selected by purposive sampling. There are five questions on the post-test that use as instrument tests. The quantitative data analysis is based on the statistical descriptive and statistical tests. The results show that students who have a high category are six students (18%), the medium category is 25 students (76%), and the low category is two students (6%). The average of all students in the sample class is 61.36, still below the KKM=76. The median test obtained 0,149 ≥ 0,025, such that it is rejected or accepted. It suggests that at the 95% confidence interval, the median student's relational understanding ability after applying the blended learning method could not reach the KKM.
