Abstract

To improve the quality of learning, learning evaluation has an important role. One of the learning evaluations that is often carried out is daily assessments to see the achievement of particular material. The aim of this research is to describe the quality of mathematics questions in statistics material for junior high school students. The method used in this research is quantitative descriptive research assisted by the AnBuSo program and R studio software. The data collection technique used documentation techniques, with data sources in the form of mathematics questions on statistics material. Question items analysis is applied to prove validity, estimate reliability, level of difficulty, discrimination, as well as analyzing the factors that cause the question items to be difficult and have poor discrimination. The respondents in this research were 200 students taken from three junior high schools in DIY. Meanwhile, qualitative data analysis is used to explain the difficulty index and discrimination of the test items. The results of this research show that the Aiken value is valid, and the reliability estimates are quite good. The results of analysis based on the CTT and IRT approaches obtained a good mean index of difficulty and discrimination. These findings imply that the validated and reliable question items can be used as a reference for developing higher-quality assessments to improve student learning outcomes.

Abstract

Many senior high school students have difficulty in understanding Linear Equation Systems (LES). The Contextual Teaching and Learning-Deep Learning (CTL-DL) approach is one of the current solutions. This study aims to describe the effect of the CTL-DL approach on students' critical thinking skills and self-confidence in the material of Linear Equation Systems. This quasi-experimental study with a pretest-posttest control group design used a population of class X students of SMA Negeri 2 Yogyakarta in the 2024/2025 academic year. Sampling was carried out by purposive sampling. Data were collected using observation sheets, critical thinking ability tests, and self-confidence questionnaires, then analyzed using the Multivariate Hotelling's T² statistical test and the independent t-test at a significance level of 0.05. The results of the study showed: 1) there was an influence of the CTL-DL approach on students' critical thinking skills and self-confidence, 2) the CTL-DL approach was significantly superior to the expository approach in improving critical thinking skills, and 3) the CTL-DL approach was significantly superior to the expository approach in improving students' self-confidence

Abstract

This study aims to analyze the quality of daily test items and non-test instruments (questionnaires) on Two-Variable Linear Equation Systems in junior high school, in terms of validity, reliability, discrimination power, and difficulty level. The method used was descriptive analysis with 64 eighth-grade students (academic year 2024/2025) as subjects. The findings show that all instruments are valid (essays are very high, multiple-choice questions and questionnaires are high), but the reliability of exam questions (essays and multiple-choice questions) is still in the moderate category. Further analysis of multiple-choice questions shows a predominance of easy difficulty levels (92%) and a number of items (25%) with poor discrimination power, indicating the need for item revision.
