Abstract

The aim of this study is to (1) develop a web-based e-module based on the Van Hiele Learning Phases and (2) assess the validity, practicability, and effectiveness of an e-module based on the Van Hiele Phases of Learning to enhance creative thinking skills. The research method was R&D by using ADDIE (analysis, design, development, implementation, evaluation) model. The students in this study have been from SMP Negeri 21 Semarang's VII grade. The Discovery Learning approach is used to implement e-modules in learning. And, according to the evaluation of the implementation of this e-module, the value of improving students' creative thinking capacity reveals that the average percentage improvement in the experimental class is 47% greater than the control class, which is 39%. The results of the classical completion test revealed that the average creative thinking capacity of students who took the Van Hiele e-module was greater than 75. (KKM) The comparison test results showed that the average gain in students' creative thinking skills in the experimental class was greater compared to the control class with a sig 0.037<0.005, indicating that the implementation of the e-module with the Van Hiele phase satisfies the effectiveness requirements. This study suggests that teaching materials be improved with more complete material, questions focused at higher order thinking abilities, and other mathematical skills.

Abstract

Kemampuan spasial mempunyai peran untuk membantu mengingat, berkomunikasi, memahami, dan bernalar tentang hubungan antar objek yang direpresentasikan dalam ruang. Salah satu usaha untuk memudahkan mahasiswa dalam memahami kemampuan spasial yaitu materi harus dikemas dengan baik dan pembelajaran dilaksanakan secara daring dan luring. Tujuan dalam penelitian ini adalah mengetahui pengaruh dari penggunaan pembelajaran blended learning terhadap kemampuan spasial mahasiswa. Penelitian ini merupakan penelitian kuantitatif jenis eksperimen semu. Metode pengumpulan data dilakukan dengan tes. Instrumen yang digunakan untuk mengumpulkan data adalah instrumen tes kemampuan spasial. Analisa data yang digunakan adalah independent sample t-test. Uji prasyarat dengan melakukan uji normalitas dan uji homogenitas. Hasil penelitian menunjukkan implementasi pembelajaran blended learning materi geometri menghasilkan kemampuan spasial yang lebih baik daripada pembelajaran konvensional. Hal tersebut dibuktikan dengan kemampuan spasial mahasiswa pada kelas eksperimen dikategorikan tinggi dengan skor rata-rata sebesar 70,93. Sementara pada kelas kontrol lebih rendah dengan rerata skor sebesar 53,79

Abstract

Penelitian ini bertujuan untuk mengetahui model hubungan kecerdasan emosional, kecemasan matematis, self efficacy dengan kemampuan penalaran statistik. Untuk mendapatkan model hubungan digunakan uji analisis jalur dengan self-efficacy sebagai variabel moderator. Teknik pengambilan data menggunakan angket dan tes. Angket digunakan untuk mendapatkan data kecerdasan emosional, kecemasan matematis, dan self-efficacy. Tes digunakan untuk mendapatkan data kemampuan penalaran statistik. Hasil analisis jalur diperoleh bahwa kecerdasan emosional berpengaruh secara signifikan terhadap kemampuan penalaran statistik baik secara langsung maupun melalui self-efficacy dengan pengaruh total 0,494. Sedangkan kecemasan matematis tidak berpengaruh secara signifikan terhadap self-efficacy maupun terhadap kemampuan penalaran statistik. Perlu pembiasaan aktifitas yang mendorong kecerdasan emosional dan self-efficacy mahasiswa. Harapannya dengan kecerdasan emosional dan self efficacy yang semakin baik akan mendorong kemampuan penalaran statistik.

Abstract

This research aims to investigate 1) students’ understanding of mathematical literacy. 2) Mathematical literacy level based on the mathematical reasoning of students with special needs (SSN) 3) Influencing factors. 4) learning process. 5) problems experienced. 6) Solutions to improve it for SSN This research was qualitative research. Data obtained through interview, quesionaire, test and documentation. The analysis techniques were data gathering, presentation, reduction, and conclution drowing or veryfiying. The data validity used triangulation techniques and sources. The findings show that 1) 3 regular students catagorized good, 1 regular students and 1 SSN were less good. 2) regular students were able to present statments, manipulate mathematics, and conclude logically while the SSN were not. 3) students’ understanding level, motivation and assitance. 4) motivation building, exercises, lecturing method. 5) no inclusive teacher, students’ low understanding, motivation and literacy level. 6) teacher traning, special assistance, exercises, lecturing method and giving trick and easy way.

Abstract

This study aims to see how the influence of the profile of Pancasila students in seventh grade junior high school students on numeracy literacy skills related to mathematical literacy. The samples in this study were students from SMP Negeri 2 and SMP Negeri 4 Cirebon City class VII totaling 56 students. The type of research used is a quantitative methodology. Data analysis in this study used descriptive statistics and inferential statistics with Pearson correlation analysis. This study uses the independent variable, namely the ability of numeracy literacy and the dependent variable, namely the character profile of Pancasila students. For data collection using questionnaires and test questions. The questionnaire contains 18 statements with 6 indicators of the Pancasila student profile and 6 test questions with 3 indicators of numeracy literacy. The results of this study indicate that the ability of numeracy literacy has a positive effect on the character profile of Pancasila students

Abstract

Abstract. Numerous research has established the impact of mathematical self-efficacy on an individual's ability to successfully solve mathematical tasks. However, according to the need for cognition paradigm, the element of difficulty in mathematics is also connected to both high and low degrees of cognitive function participation. This study intends to evaluate the contribution of one's need for cognition to one's degree of mathematical self-efficacy. 40 students studying at Mathematics Education Department in Sebelas April University Sumedang, Indonesia, participated in this study. The need for cognition and mathematical self-efficacy questionnaires, which used Likert scale scoring, were used to gather the data, which was then analyzed using correlational and regression methods. The findings revealed a significant and strong correlation between student need for cognition and mathematical self-efficacy. In addition, the need for cognition has also been shown to have a significant and positive impact on students' mathematical self-efficacy. This means that a higher level of student needs for cognition will lead to a higher level of mathematical self-efficacy.
