Abstract

The purpose of this study was to confirm the factors that influence the sociomathematics norm. The method used in this research is the ex post facto. The subjects in this study were seventh-grade junior high school students in the city of Yogyakarta, Indonesia (264 students) taken by cluster random sampling. The instrument used was a sociomathematics norm observation sheet consisting of four factors are (1) the experience of mathematics, (2) the explanation of the mathematics, (3) mathematical differences, (4) mathematical communication. Data analysis using structural equation models with the Confirmatory Factors Analysis. The results showed that the modified path analysis obtained goodness of fit mostly in the fit category, so overall the sample covariance matrix is the same as the estimated covariance matrix.

Abstract

Tujuan dari penelitian ini adalah untuk mengetahui efektivitas model pembelajaran kooperatif tipe Team Games Tournament (TGT) dan Numbered Head Together (NHT) terhadap hasil belajar matematika ditinjau dari motivasi belajar siswa. Penelitian ini merupakan true experiment dengan subjek seluruh siswa kelas VII di MTsN 7 Sleman. Teknik pengumpulan data yang digunakan yaitu teknik angket, tes dan dokumentasi. Instrumen tes hasil belajar matematika yang digunakan, memenuhi validitas, tingkat kesukaran, daya beda dan reliabilitas, sedangkan angket motivasi belajar memenuhi validitas dan reliabilitas. Analisis variansi (anava) dua arah digunakan untuk menganalisis data dan dilanjutkan dengan uji pasca anava. Hasil dari penelitian ini adalah: (1) terdapat perbedaan hasil belajar matematika antara siswa dengan perlakuan TGT dan NHT; (2) terdapat perbedaan hasil belajar siswa bermotivasi tinggi, sedang, dan rendah dan (3) tidak terdapat interaksi antara model pembelajaran dan motivasi belajar siswa terhadap hasil belajar matematika siswa.

Abstract

Penelitian ini bertujuan untuk mengetahui persepsi mahasiswa terhadap perkuliahan online, untuk mengetahui bentuk-bentuk aplikasi yang digunakan dalam perkuliahan online dan untuk mengetahui keunggulan dan kelemahan perkuliahan online yang dilaksanakan di prodi pendidikan matematika. Penelitian ini menggunakan metode deskriptif kuantitatif. Penelitian ini dilakukan di Prodi Pendidikan Matematika FKIP UST Yogyakarta. Populasi penelitian ini adalah seluruh mahasiswa prodi pendidikan matematika pada semester genap sedangkan sampel penelitian ini adalah mahasiswa semester 2 Prodi Pendidikan Matematika  FKIP UST pada Semester Genap Tahun Akademik 2019/2020. Teknik pengumpulan data menggunakan angket dan wawancara. Teknik analisis data secara deskriptif kuantitatif. Diperoleh hasil bahwa perkuliahan di prodi pendidikan matematika dilaksanakan secara online dimana para dosen menggukan media yang mereka kuasai. Hal tersebut juga disepakati dengan mahasiswa, persepsi mahasiswa terhadap pembelajaran online di prodi pendidikan matematika pada aspek keterampilan paling banyak menjawab sering, aspek pembelajaran paling banyak menjawab sering sedangkan pada aspek sarana dan prasarana  paling banyak menjawab jarang, bentuk aplikasi yang digunakan oleh para dosen saat perkuliahan online adalah portal akademik, whatsapp group, youtube,  zoom, google meet, dan google classroom. Keunggulan perkuliahan online adalah waktunya fleksibel. Kelemahan perkuliahan online yaitu mahasiswa merasa bosan dan sulit memahami materi.

Abstract

This study aims (1) to determine the differences in problem-solving abilities of students who learn to use e-worksheets and do not use e-worksheets (2) to determine differences in problem-solving abilities between students who have low, medium, and high interests (3) to find out whether there is an interaction or not between the use of e-worksheet in terms of learning interest on students' problem-solving abilities. This research is a quantitative study with a quasi-experimental with a non-equivalent control groups design. The subjects of this study were students of class VII B and VII C of SMP Negeri 4 Sewon with 30 students each. The technique of taking the subject is using cluster random sampling. The instrument used in this research is a questionnaire of students' interest in learning mathematics and a test of problem-solving abilities. Data analysis in this study used factorial design analysis of variance. The results of this study indicate that (1) there are differences in the problem-solving abilities of students who learn using e-worksheets and do not use e-worksheets, (2) there are differences between students who have an interest high, medium, and low learning on problem solving abilities, (3) there was no interaction between the use of e-worksheets in terms of interest in learning to ability In solving students' problem solving, the results of the analysis showed that the results were not significant.

Abstract

This research is development research that was held on in August 2021 and aims to produce a circle learning media based on Geogebra Applets to reinforce the creative thinking ability of students in class XI of Senior High School. The development method used in this research is the first three steps in the 4-D development model consisting of: (1) define; (2) designs; (3) develop and limited to validity and practicality tests. Data at the define stage was collected using the documentation method, while at the development stage it was collected using a content validity questionnaire and student response questionnaires which were then analyzed descriptively by statistical analysis. This study gives the results that: (1) the circle learning media based on Geogebra Applet that was developed, is very valid with an average score of 3.83; (2) students gave a very good response with a percentage of 86.48% of the circle learning media. These results indicate that the circle learning media based on the Geogebra Applet that was developed is valid and practical. This research is expected to be a reference for further research related to the development of learning media based on Geogebra Applet.
