This research aimed to explore learning obstacles when students are given a Trigonometry problem in the mathematical understanding ability. Learning obstacles are constraints faced during learning and result in less than optimal learning. The given trigonometric material is just about the number and the difference of the cosine sinus. Trigonometry material given based on students' mathematical understanding ability. The ability of mathematical understanding based on 2 indicators is the ability of instrumental understanding and the ability of relational understanding. This research was conducted on students of class XI IPA 1MAN 3 Majalengka. This research method using qualitative approach by analyzing student answer result. The results of this study found some barriers to learning both are instrumental understanding and relational understanding.

Penelitian ini bertujuan memberikan informasi yang detail tentang proses validitas isi, validitas butir, dan reliabilitas instrumen evaluasi berbasis model Alkin sebagai alat evaluasi pelaksanaan blended learning mata kuliah Matematika Diskrit di STIKOM Bali. Penelitian ini menggunakan pendekatan penelitian pengembangan instrumen, dengan tahapan-tahapan yaitu: pendefinisian variabel, penjabaran variabel menjadi indikator, penyusunan butir-butir instrumen, uji coba instrumen, serta analisis validitas dan reliabilitas instrumen. Subjek dalam penelitian ini adalah seorang pakar pendidikan informatika dan seorang pakar evaluasi pendidikan yang menguji validitas isi instrumen, sedangkan sebanyak 50 orang mahasiswa dilibatkansebagai responden dalam penentuan validitas dan reliabilitas butir instrumen. Alat pengumpulan data berupa kuesioner dan foto dokumentasi. Analisis validitas isi instrumen dilakukan melalui perhitungan Gregory , analisis validitas butir instrumen melalui perhitungan korelasi pearson–product moment , dan analisis reliabilitas instrumen melalui perhitungan koefisien Cronbach Alpha . Hasil penelitian ini menampilkan validitas isi dan reliabilitas instrumen yang tergolong dalam kriteria sangat baik.

Kajian ini dilatarbelakangi dari hasil diskusi dengan guru, data awal berupa tes kemampuan kognitif dan pengamatan di kelas tentang masalah yang sering dihadapi dalam pembelajaran matematika terkait vektor. Masalah yang muncul antara lain: siswa kurang mampu memahami konsep matematika pada materi vektor. Siswa cenderung dapat mengerjakan soal sesuai dengan contoh yang diberikan namun kurang mampu mengerjakan soal yang berbeda dengan contoh. Hal ini disebabkan pembelajaran matematika materi vektor yang berlangsung di sekolah masih bersifat informatif dan abstrak, sehingga pemahaman konsep pada materi vector kurang dipahami. Penelitian ini bertujuan untuk mengembangkan desain pembelajaran materi vektor yang dapat meningkatkan pemahaman konsep matematika pada materi vector yang didasrakan pada hasil analisis hypothetical learning trajectory (HLT) terhadap kemampuan kognitif siswa. Penelitian ini bersifat deskriptif dengan jumlah sampel 30 siswa di SMA Negeri 2 Kabupaten Tangerang. Hasil penelitian memberikan informasi untuk kajian penelitian selanjutnya dalam upaya pengembangan desain didaktik yang dihipotesiskan dapat meningkatkan pemahaman konsep dengan kemampuan pemecahan masalah siswa pada materi vektor.

The research was conducted to learn about the effect of effective learning behavior on students' cognitive-psychomotor skills in class IX mathematics learning at MTs Ash-Shiddiqiyyah Sumber Cirebon. This method of research is quantitative research. The population of this research is composed of all students of class IX MTs Ash-Shiddiqiyyah, The sample of this research is class IX B with a total of 24 students taken from Cluster Random Sampling. The data collection techniques used are 2, ie questionnaires for effective behavioral data and test data for the cognitive-psychomotor skills of students. The technique of data analysis for hypothesis testing is a simple regression analysis technique. The result of this research shows that the result of t-count = 7.522 is greater than t-table = 0.404 so it means that there is an influence between an effective learning behavior towards the ability cognitive-psychomotor of the student in mathematics

The role of mathematics is very important in daily life, therefore the subjects of mathematics are taught in every level of education, from kindergarten to college. This study aims is to describe the mathematical communication ability of grade VIII students of MTs Fatahillah which amounts to 30 students in understanding triangular and rectangular materials. Another aims arevto know students learning osbtacle related to communication skills. Instruments of this study are written test. The results of this study is show that the students difficulties are they do not memorize the formula, interpreting solution mistakes because students does not pay attention to questions, and students difficult to understand about the problem that given to them.
