Abstract

This research aims to determine the effect of Adversity Questions (AQ) on junior high school students' numeracy abilities in solving Minimum Competency Assessment (AKM) questions and analysis of students' numeracy abilities in terms of their Adversity Quotient. The research was carried out at SMP Negeri 4 Semarang with a sample size of 157 class VIII students. This research is a combination research (mix method) type The Explanatory Sequential Design. The research results show that there is a significant influence between AQ on junior high school students' numeracy abilities in solving AKM questions. This is proven by testing two variables which shows that the significance value of the AQ variable is less than α with a value of 0.000 (0.000 ≤ 0.05). The simple linear regression equation obtained is Ŷ = 20.731 + 0.318X. This states that for every additional unit of AQ value (X), the student's numeracy ability value (Y) increases by 0.318. The coefficient of determination obtained was 0.342, which means that the influence of AQ on students' numeracy abilities was 34.2%, while survival was 65.8% influenced by other variables. The numeracy abilities of students in solving AKM questions in each AQ category obtained the following results: 1) The numeracy abilities of students in the Quitter category only reached the cognitive understanding process well, but the standard cognitive process was not optimal, so Quitter students did not reach the on cognitive reasoning processes. 2) The numeracy abilities of students in the Camper category have reached the understanding process well, as well as the cognitive process of application, but the reasoning process has not been maximized. 3) The numeracy abilities of students in the Climber category in the understanding, application and reasoning process are maximal.

Abstract

The low level of students' understanding of mathematical concepts is a crucial problem in education that has an impact on academic achievement in general, so innovation in learning methods is needed. This study aims to compare the effectiveness of video-based learning (VBL) and game-based learning (GBL) in improving students' understanding of mathematical concepts. This study adopted a quasi-experimental design with two experimental classes, each using the VBL and GBL methods, and a control class with traditional learning methods. The research instruments were pre-test and post-test essay tests that were validated and reliable. The results of data analysis using One Way ANOVA proved that there were significant differences between the 3 groups. The VBL and GBL approaches proved to be more effective than the traditional approach in improving students' mathematical understanding of mathematical concepts. This study suggests the use of video and game-based learning methods as innovative alternatives to improve the quality of mathematics learning in schools.

Abstract

This study aims to examine the effectiveness of the STEM-based Gallery Walk learning model on improving students' mathematical reasoning at MTs NU Al-Hidayah Kudus. The method used was a pseudo-experiment with a Pretest-Posttest Control Group Design. Cluster random sampling was applied in sample selection, where class VII B was the experimental class and class VII A was the control class. The research instrument was in the form of description questions based on mathematical reasoning indicators, and had been tested for validity, difficulty level, distinguishing power and reliability. Data analysis used binomial testing, Mann-Whitney U, and N-Gain calculation. As a result, the experimental class achieved classical completeness of 86%, more than the set limit of completeness (75%). The Mann-Whitney U test showed that the average value of mathematical reasoning improvement of the experimental class was more than the average value of mathematical reasoning improvement of the control class. The N-Gain calculation shows an increase of 76.5% which is categorized as effective. This means that the STEM-based Gallery Walk learning model is proven effective in improving students' mathematical reasoning skills. Thus, this model can be recommended as an alternative innovative teaching strategy to improve mathematical thinking skills.
