This study aims to determine whether learning assisted by YouTube learning videos can improve student learning outcomes in the material of composition functions and inverse functions. This research is a Classroom Action Research conducted at Madrasah Aliyah Negeri 1 Indramayu. The subjects in this study were students of class X MIPA 1, totaling 23 students. The instrument used in this research is a formative test given every cycle to measure the increase in student learning outcomes in mathematics. The data processing learning outcomes obtained an average of 49.02 in the first and76.82 in the second. Likewise, from the increase in the number of students who achieve mastery learning, namely from the first cycle, as many as 5 of 23 students or 21% with shallow completeness criteria, in the second cycle, 20 of 23 students or 91% withvery high completeness criteria. Based on these results, it can be said that the learning outcomes of the composition function and inverse function material can be increased with the help of learning videos from youtube.This study aims to determine whether learning assisted by YouTube learning videos can improve student learning outcomes in the material of composition functions and inverse functions.

IIMPLIKASI STRATEGI CREATIVE PROBLEM SOLVING (CPS) DALAM UPAYA PENINGKATAN KEMAMPUAN REPRESENTASI MATEMATIS DAN DAMPAKNYA TERHADAP MATHEMATICS ANXIETY SISWA SMP

Rendahnya kemampuan representasi matematis dan terlihatnya kecemasan matematika siswa SMP Nusantara Bandung merupakan permasalahan yang menuntut pendidik untuk dapat menciptakan dan menerapkan suatu strategi baru dalam pembelajaran. Penelitian ini merupakan metode campuran (Mixed Method) tipe Embedded Desain dengan jenis Embedded experimental model dengan desain penelitian berbentuk pretes-postes control grup design. Tujuan penelitian ini untuk melakukan studi yang berfokus pada penggunaan strategi Creative Problem Solving (CPS) yang diduga dapat meningkatkan kemampuan representasi matematis dan dampaknya terhadap kecemasan matematika siswa. Populasi dalam penelitian ini adalah siswa kelas VII SMP Nusantara Bandung. Pemilihan sampel dilakukan dari populasinya secara purposif (purposive sampling) yaitu kelas VII A yang diberi perlakuan dengan strategi CPS dan VII B dengan pembelajaran ekspositori. Instrumen yang digunakan dalam penelitian ini adalah tes kemampuan representasi matematis, angket kecemasan matematika, lembar observasi, dan wawancara. Berdasarkan analisis data diperoleh kesimpulan bahwa (1) Peningkatan kemampuan representasi matematis siswa laki-laki dan perempuan yang memperoleh strategi CPS sama dengan siswa laki-laki dan perempuan yang memperoleh pembelajaran ekspositori, (2) Siswa laki-laki dengan perempuan yang menggunakan strategi CPS mempunyai kecemasan matematika (Mathematics Anxiety) yang berbeda, siswa perempuan yang menggunakan strategi CPS mempunyai Mathematics Anxiety yang berbeda dengan siswa laki-laki yang menggunakan pembelajaran ekspositori, (3) Terdapat pengaruh negatif kemampuan representasi matematis terhadap kecemasan matematika dari kategori jenis kelamin siswa, (4) Guru terbiasa menggunakan strategi CPS dari pertemuan ketiga dan aktivitas siswa dalam mengikuti proses CPS rata-ratanya naik dari kriteria sedikit sampai menjadi banyak. Hasil respon siswa menunjukan bahwa strategi CPS lebih menarik dan lebih baik jika dibandingkan dengan pembelajaran ekspositori

The potential of mobile augmented reality as a didactic and pedagogical source in learning geometry 3D

The COVID-19 pandemic in Indonesia requires teachers and students to perform learning activities online. Meanwhile, teachers use a variety of technology products in the classroom without paying attention to the didactic, pedagogical, and content aspects. This is due to time constraints and short learning adjustments that should be flexible to this pandemic. Therefore, this research provides an alternative by exploring the potential of augmented reality as a didactic and pedagogical source in learning geometry. An exploratory case study design was used to reveal this potential, while three mathematics teachers and twenty-six students from three schools in Indramayu Regency, Indonesia, participated in the research. Data from observations and documentation were checked, extracted, entered verbatim, and coded. The results of the interview data were analyzed using the content analysis method, while those from the geometry understanding test and student response questionnaires used descriptive analysis. Consequently, the research results showed that augmented reality was useful as an alternative didactic and pedagogical source of learning geometry during the COVID-19 pandemic. This conclusion was based on the reason, first characteristically augmented reality technology can be integrated with textbooks or certain learning methods. Second, the results of the geometry understanding test showed that there were more students who answered the questions correctly than the students who answered incorrectly. Third, the results of questionnaires and interviews showed that students had a positive attitude during the geometry learning process. Therefore, the researcher believes that the use of augmented reality is worthy of being an alternative didactic and pedagogical source and has the potential to be applied to other subjects both during the COVID-19 pandemic and after the COVID-19 pandemicPeer Reviewe

Analysis of Mathematics Literation Capability in Cube and Beam Materials on Mts Students Reviewed from Dependent and Independent Field Kognitiffield Style

This research is a descriptive qualitative research which aims to describe the mathematical literacy skills of the material of cubes and beams of class VIII A students at MTsN 2 Indramayu that it be seen in terms of cognitive styles of dependent fields and independent fields. Data will be whereas to describe the ability of mathematical literacy using observation; interview test; documentation. Data from this study were analyzed using Miles and Huberman (2007) data analysis which consisted of data reduction,datapresentation,andconclusiondrawing.Theresultsofthisstudyindicate that students in the Field Dependent cognitive style use the concept and the steps of the test work are still not appropriate. While students in Field Independent cognitive style use the right concepts and work steps. The advice given is that the teacher should provide balanced proportions in giving individual and group assignments to students (more conical).     Keywords: Mathematical literacy ability, Field Dependent, Field Independent
