Abstract

The purpose of this study is to examine how deep learning influences students’ mathematical critical thinking skills. In mastering mathematics—which requires reasoning, analysis, and systematic review—critical thinking is essential to address the challenges of the 21st century. This research employs a quasi-experimental design using a pretest-posttest control group model. The subjects of the study were eighth-grade junior high school students, divided into an experimental group and a control group. The main instruments used were a mathematical critical thinking skills test and a learning activity observation sheet. The findings indicate that students who participated in instruction based on a deep learning approach showed a significant improvement in critical thinking skills compared to those who received conventional instruction. Unlike students who underwent standard learning methods, those exposed to deep learning strategies experienced a notable enhancement in their critical thinking abilities. Based on these findings, the implementation of deep learning is recommended more broadly in mathematics classroom instruction.

Abstract

Learning mathematics, particularly in the area of solid geometry, is often perceived as difficult by elementary school students, which highlights the need for appropriate learning media to support their understanding. This study aims to examine the effectiveness of learning media based on the Amazing Geometry Augmented Reality application in introducing solid geometry concepts to students. The research employed a pre-experimental design using a one-group pre-test and post-test. The population and sample consisted of all fifth-grade students at SDN Margodadi, totaling 11 students, selected through saturated sampling. Data were collected using essay tests that had undergone content and empirical validation, as well as reliability testing. Data analysis involved descriptive statistics, a normality test, and a paired sample t-test using IBM SPSS 26. The results showed that the average post-test score was higher than the pre-test score. The paired sample t-test indicated a t-count value of 15.486, which was greater than the t-table value of 1.812, with a significance level (2-tailed) of less than 0.05. These findings demonstrate that the use of the Amazing Geometry Augmented Reality application has a significant positive impact on students’ understanding of solid geometry. Overall, this study suggests that integrating augmented reality into mathematics instruction can enhance the learning process, particularly in the introduction of spatial concepts, and offers valuable implications for the broader use of technology in elementary mathematics education.

Abstract

Reading is a fundamental part of language proficiency, especially in Indonesian, which is the national language. Therefore, mastering early reading skills is a prerequisite for mastering other language skills. Finding out whether the use of word card media has an impact on students' reading skills is the purpose of this study. This study used a quasi-experimental research design. Reading assessment was used to collect data. The reliability of the instrument was tested with the split-half method, while its validity was based on content validity. It is recommended that teachers use card media to teach beginning reading in grade two elementary school because the use of word card media can affect students' beginning reading ability. The results showed that the significance value (2-tailed) was 0.05 in accordance with the two means difference test with t-test using SPSS software with a significance level of 0.05. Since the sig value is 0.05, H0 is rejected for the test of the average difference in the final score of students' beginning reading ability, especially between two parties. This indicates that there is a difference between students who use word card media and those who do not use word card media. Keywords: Students' Reading Ability, Word Card Media

Abstract

The study assessed the numeracy skills of junior high school students. The participants of this study were eighth-grade students from SMP Negeri 01 BP Peliung enrolled in ANBK. The tools in this study were a numeracy proficiency assessment and an interview questionnaire. The numeracy skill assessment in this study was administered to students utilizing Google Workspace and comprised six questions. The numeracy questions administered to students consist of AKM-type inquiries, including multiple-choice, complex-choice, true-false, and descriptive questions. This research involved interviews with six subjects, categorized into high, medium, and low numeracy skills, with two subjects in each category. This interview was conducted to assess students' numeracy skills based on seven components encompassed within three indicators of numeracy skills. Individuals with high numeracy proficiency demonstrate that all three indicators of numeracy are satisfied. Those with moderate numeracy proficiency meet only two indicators, specifically the skill to formulate situations and employ mathematical concepts, procedures, facts, and reasoning. Conversely, individuals with low numeracy proficiency fulfil only one indicator, the skill to formulate the situation.
