Abstract

Until now, there have been many studies conducted on mathematical reflective thinking skills presented using problem-based learning models. This study aims to analyze published research on the effectiveness of problem-based learning models on mathematical reflective thinking skills. The method used is meta-analysis. The data analyzed were 8 journal articles that were used to determine the effect size. Data collection was carried out using a variable coding sheet as a coding instrument. The collected data were then analyzed using meta-analytic statistical techniques. The results of the analysis showed that the average effect size of the 8 articles was 2.63, which was included in the high effect size category. Of the 8 articles analyzed, 6 articles (75%) showed a high effect size category, while 2 articles (25%) showed a medium effect size category. The article with the highest effect size, which reached 5.29, shows that the problem-based learning model can provide a very significant increase in students' mathematical reflective thinking skills in learning mathematics.

Abstract

The ability to think logically in mathematics is a skill that must be developed through instruction. One strategy for developing this ability is the use of high-quality instruments. Therefore, this study aims to analyze the quality of a mathematical logical thinking ability test instrument in terms of its validity, reliability, difficulty index, and discriminating power using SPSS and Microsoft Excel. This research employed a quantitative method with an evaluative analysis approach. The subjects in this study were students of class VII.6 and VII.8 at SMPN 26 Bandarlampung. The instrument used was a descriptive test consisting of ten items, developed based on four indicators of logical thinking ability, namely the ability to interpret information, the ability to predict, the ability to solve problems, and the ability to draw conclusions. The results of this study indicate that: (1) the quality of the logical thinking ability test instrument meets the criteria for 100% validity; (2) the reliability of the logical thinking ability test instrument is 0.775, categorized as reliable; (3) the difficulty level analysis shows that nine items fall into the moderate category and one item falls into the easy category; (4) the discrimination power analysis shows that four items have good discriminating power and six items have fair discriminating power.

Abstract

The integration of computational thinking in mathematics learning is essential to support 21st-century skills; however, assessment practices in schools still inadequately measure students’ thinking processes. This study aims to analyze the quality of a test instrument designed to measure junior high school students’ computational thinking ability on ratio material. A quantitative descriptive-evaluative method was employed involving 64 seventh-grade students. The instrument consisted of five contextual essay items developed based on computational thinking indicators: decomposition, pattern recognition, abstraction, generalization, and algorithmic thinking. Item analysis was conducted to examine validity, reliability, difficulty index, and discrimination power. The results indicate that all items were valid and the instrument showed high reliability (α = 0.81). The difficulty levels ranged from easy to moderate, while the discrimination power was categorized as sufficient to good. These findings demonstrate that the instrument is valid, reliable, and appropriate for measuring students’ computational thinking ability in mathematics learning at the junior high school level.

Abstract

This study aims to analyze the quality of an essay test instrument measuring students’ mathematical representation ability on eighth-grade statistics material, which was administered to ninth-grade students at SMP Negeri 1 Bandar Lampung. The analysis covers item validity, reliability, difficulty level, and discrimination index. This study employed a quantitative approach with a descriptive method. The research subjects were 27 ninth-grade students, while the object of the study consisted of six essay items on statistics that were developed based on indicators of mathematical representation ability. The results show that only three items (numbers 2, 4, and 6) meet the validity criteria, while items 1, 3, and 5 are invalid. The reliability coefficient of the instrument is 0.685, which falls into the moderate category and is therefore acceptable. All items are categorized as easy based on the difficulty index analysis. However, the discrimination index analysis indicates that all items have low discrimination power and thus fail to distinguish between high- and low-ability students. These findings imply that the instrument requires comprehensive revision, particularly in terms of difficulty level and item quality, in order to more accurately measure students’ mathematical representation ability in statistics.
