Abstract

This study aims to determine the role of motivation by looking at the effect of emotional intelligence, lecturers' teaching style and learning media facilities on statistical understanding. The sample in this study was 239 respondents who were students majoring in Accounting at Prima Indonesia University. The data is processed using path analysis. Emotional intelligence, teaching style of lecturers and learning media facilities strongly support motivation to be better. In learning the teaching style of the lecturer is very supportive in growing student motivation, if the lecturer as the main actor in learning has good pedagogical abilities and uses effective learning media in teaching, it will be able to grow student learning motivation and will produce a high level of understanding in the subject. . Students who have good emotional intelligence will have good behavior and motivation in learning. Therefore, the influence of motivation can be seen from emotional intelligence, lecturer's teaching style and learning media facilities in understanding statistics.

Abstract

Communication skills and dispositions is very important mathematical owned by students to solve problems concerning mathematical concepts. In this study, analyzed the differences increase communication skills and dispositions given mathematical model of problem based learning and discovery. The method used in this research isquasi experiment and sampling techniques performed with simple random sampling.Inferential analysis of data performed by analysis of covariance, The results showed that increased communication abilities were given a mathematical problem based learning models larger than the discovery at 12.61. This is evident from the difference in value of the constant regression model of problem based learning is 31.89 and discovery that is 19.28, and increased by mathematical disposition of problem based learning models larger than the discovery of 12.41, This is evident from the difference score regression equation constant problem based learning models that 42.69 is greater than the discovery that 30.28,

Abstract

Penelitian ini bertujuan untuk mengetahui hasil belajar matematika siswa kelas VIII-2 MTs Cerdas Murni Medan T.P 2012/2013 sebelum dan setelah menggunakan metode pembelajaran Giving Question And Getting Answer. Jenis penelitian yang digunakan dalam penelitian ini adalah penelitian tindakan kelas yang terdiri dari dua siklus. Penelitian ini menggunakan tes hasil belajar matematika dalam bentuk pilihan ganda pada materi kubus dan balok. Tes ini dilakukan sebanyak tiga kali yakni tes awal (pre test), tes hasil belajar I (post test I) dan tes hasil belajar II (post test II). Subjek penelitian ini adalah siswa kelas VIII-2 MTs Cerdas Murni Medan yang berjumlah 29 orang. Berdasarkan hasil observasi pada setiap pertemuan, menunjukkan bahwa: 1) Berdasarkan tes awal (pre test) diperoleh persentase ketuntasan belajar secara klasikal sebesar 34,48% berjumlah 10 siswa. 2) Hasil belajar matematika siswa pada materi kubus dan balok setelah digunakan metode pembelajaran Giving Question And Getting Answer pada siklus I yakni siswa yang tuntas belajar secara klasikal 51,72% berjumlah 15 siswa. Pada siklus II diperoleh siswa yang tuntas belajar secara klasikal 86,21% berjumlah 25 siswa. Hasil belajar siswa dari pre test ke siklus I meningkat sebesar 17,24%, dari siklus I ke siklus II meningkat sebesar 34,49%. Dengan demikian, hasil belajar siswa semakin meningkat dan telah mencapai ketuntasan belajar. 3) Respon siswa setelah diajarkan dengan menggunakan metode ini mengalami peningakatan sebesar 0,5, dari siklus I bernilai 3,5 dan siklus II nilai 4. 4) aktivitas guru juga mengalami peningkatan sebesar 0,24, pada siklus I memperoleh nilai 3,76 dan pada siklus II mengalami peningkatan nilai menjadi 4. Berdasarkan hasil penelitian tindakan kelas di atas, maka dapat disimpulkan bahwa penggunaaan metode pembelajaran Giving Question And Getting Answer (GQGA) dalam pembelajaran matematika pada materi kubus dan balok dapat meningkatkan hasil belajar siswa dikelas VIII-2 MTs Cerdas Murni Medan T.P 2012/2013.
