Abstract

This study aims to increase students' interest in mathematics. Students can use number card learning media as an alternative method of learning integers (addition and subtraction). In mathematics, the material on integers (addition and subtraction) discusses abstract properties in mathematics. Based on this study, the study was conducted through observation of class VII students at MTs Altihadul Wathoniayah. This research takes the type of quantitative research through an experimental approach and uses a Pretest-Posttest Design. This research involves all class VII MTs Al Ittihadul Wathoniyah, both class VII-A and VII-B. However, the sample used randomly is type VII-A which consists of 30 samples used in this study to conduct tests to collect data on reasoning skills and mathematics learning outcomes. After testing with the hypothesis that the calculated value is greater than the table's t value. The results of the data show that the use of number cards in conducting research on mathematics learning media is effective in increasing students' interest in learning mathematics subjects and achieving satisfactory results.

Abstract

A student's ability to solve math problems is very, very low because in solving math problems, the learning process does not accustom students to think more creatively. This is because the learning process in the teacher's class still applies conventional methods, and the students in the class have not yet achieved scores above the KKM. This study aims to see the Creative Problem Solving learning model as a series of learning in solving and solving problems systematically based on student creativity to produce effective solutions. This research is a quasi-experimental research using purposive sampling technique. The instrument used in this research is a test of the ability to solve mathematical problems in the form of a written test, a result test and an observation sheet on the implementation of the learning process. The data analysis techniques used are descriptive statistical analysis and inferential statistical analysis. The results of the study show that the mathematics learning of students using the CPS learning model on the ability to solve mathematical problems of students is better than the results of mathematical learning of students who have followed conventional learning which means that there is an influence of creative problem solving learning on the ability to solve mathematical problems of high school students regarding linear inequalities .

Abstract

Penelitian ini bertujuan melihat apakah ada peningkatan hasil belajar siswa menggunaan Pendekatan Saintifik. Pendekatan Saintifik merupakan pendekatan yang digunakan dalam pendidikan lewat proses ilmiah yang dicoba lewat kegiatan mengamati, menanya, berupaya, menalar, serta mengkomunikasikan. Siswa yang memiliki nilai hasil belajar rendah umumnya disebabkan karena ketidak mampuan mereka mengerjakan matematika bagaimanapun usaha mereka. Semakin mereka berusaha untuk menjawab pertanyaan guru atau soal yang diberikan mereka semakin mereka merasakan pusing. Sehingga ketika menghadapi soal mereka lebih memilih untuk melihat pekerjaan teman, atau bahkan tidak mengerjakan soal tersebut sama sekali dan mempersiapkan diri untuk menerima hukuman atau sanksi dari guru. Populasi yang digunakan dalam penelitian ini adalah siswa kelas VIII SMP N 2 Bila Hulu. Mengetahui seberapa besar peningkatan kemampuan siswa dalam representasi menyelesaian soal setelah menggunakan pembelajaran dengan Pedekatan Saintifik.Rata-rata nilai hasil belajar siswa sebelum dan sesudah adanya penerapan dimana nilai rata-rata pre-test eksperimen adalah 42.56 dan pre-test kontrol adalah 50.56% menjadi 79.16% untuk post-test eksperimen dan 71.44% untuk post-test kontrol. Kesimpulan hasil penelitian ini adalah nilai hasil belajar siswa dengan menggunakan pendekatan saintifik lebih baik, dari kemampuan siswa saat melaksankan pembelajaran konvensional siswa SMP VIII Negeri 2 Bilahulu. Dengan hasil presentasi  pembelajaran eksperimen menggunakan pendekatan saintifik 36.60% dan kelas kontrol adalah sebasar 20.88%.

Abstract

Students’ scientific literacy remains low due to the continued use of conventional learning methods that are less contextual and interactive. This study aims to determine the effect of context-based and creative digital teaching materials on students’ scientific literacy. A quasi-experimental pretest-posttest control group design was used involving 60 seventh-grade students divided into an experimental class (n = 30) and a control class (n = 30). The instruments included scientific literacy tests, questionnaires, and observation sheets. The results showed that the average posttest score of the experimental class (30.03) was significantly higher than that of the control class (24.50), with t(58) = 2.38, p = 0.021. The N-Gain value of the experimental class was 0.21 (low category), which was higher than the control class at 0.004 (low category). These findings indicate that context-based and creative digital teaching materials are effective in improving students’ scientific literacy, although the level of improvement remains low.

Abstract

This study aims to analyze the effect of implementing the Inquiry Cooperation assisted by GeoGebra software on students’ mathematical critical thinking skills. This research employed a quantitative approach using a quasi-experimental method with a pretest–posttest control group design. The sample consisted of 60 students who were divided into an experimental group and a control group. The research instrument was a multiple-choice test consisting of 15 items that had met the criteria of validity and reliability. Data were analyzed using both descriptive and inferential statistics, including normality tests, homogeneity tests, paired sample t-tests, independent sample t-tests, and N-Gain analysis. The results showed that the average score of students’ mathematical critical thinking skills in the experimental group increased from 6.60 to 7.67, while the control group showed only a minimal improvement. The independent sample t-test yielded a significance value of 0.006 (< 0.05), indicating a significant difference between the two groups. Furthermore, the experimental group achieved an N-Gain score of 56.26% (moderately effective category), whereas the control group obtained 15.20% (ineffective category). Therefore, it can be concluded that the implementation of the Inquiry Cooperation Model assisted by GeoGebra has a positive and more.   Keywords: Mathematical Critical Thinking, GeoGebra, Inquiry Cooperation Model.

Abstract

This study aims to examine the effectiveness of applying time management techniques in self-directed mathematics learning. A quasi-experimental method with a pre-test and post-test control group design was employed. The subjects were 60 seventh-grade students of SMP Negeri 5 Bilah Barat, divided into an experimental group (n=30) receiving the Pomodoro technique intervention and a control group (n=30) engaging in conventional self-study. Data were collected through learning achievement tests, a time management habits questionnaire, and learning logs. Data analysis utilized descriptive statistics, prerequisite tests (normality and homogeneity), and an Independent Sample T-Test at a 5% significance level. Results revealed that the experimental group's post-test mean (84.17) was significantly higher than the control group's (72.30) with t = 6.971 and p = 0.000. The mean N-Gain of the experimental group was 0.62 (moderate category) and the control group 0.34 (moderate category), indicating a greater improvement in the experimental group. Most students (86.7%) fell into the high and very high categories in applying time management techniques. Thus, the application of time management techniques proved effective in improving mathematics learning outcomes in a self-directed learning context.
