Since the impressive works of Talagrand, concentration inequalities have been recognized as fundamental tools in several domains such as geometry of Banach spaces or random combinatorics. They also ...turn out to be essential tools to develop a non-asymptotic theory in statistics, exactly as the central limit theorem and large deviations are known to play a central part in the asymptotic theory. An overview of a non-asymptotic theory for model selection is given here and some selected applications to variable selection, change points detection and statistical learning are discussed. This volume reflects the content of the course given by P. Massart in St. Flour in 2003. It is mostly self-contained and accessible to graduate students.

An engagingly-written account of mathematical tools and ideas, this book provides a graduate-level introduction to the mathematics used in research in physics. The first half of the book focuses on ...the traditional mathematical methods of physics – differential and integral equations, Fourier series and the calculus of variations. The second half contains an introduction to more advanced subjects, including differential geometry, topology and complex variables. The authors' exposition avoids excess rigor whilst explaining subtle but important points often glossed over in more elementary texts. The topics are illustrated at every stage by carefully chosen examples, exercises and problems drawn from realistic physics settings. These make it useful both as a textbook in advanced courses and for self-study. Password-protected solutions to the exercises are available to instructors at www.cambridge.org/9780521854030.
The development of information and communication technology has an impact on the need for innovative resources and is able to solve problems properly. This makes education an important thing to pay ...attention to and one of them is with mathematics subjects. One of the focuses in mathematics is the HOTS problem where in its application and work, each student is different. The purpose of this study is to describe the ability of mathematical literacy in solving HOTS problems. The method used in this study is qualitative with data tringaluation. The stage of this study is the collection of data as a whole using two questions that are shared with all students and supported by interviews. The results of this study show that overall mathematical literacy skills in students, the use of HOTS-type mathematics problems in mathematics learning is able to achieve mathematical literacy indicators. However, the mathematical literacy ability in students is different, namely male students have better literacy than female students in solving HOTS problems. Male students can solve problems completely and in sequence, while female students are less coherent in doing the questions.

The team teaching method is a teaching method that is carried out by more than one teacher in a group of similar students by distributing their tasks, watching over them with one and another, ...evaluating the lesson, and complimenting each other to increase the learning outcomes of the students. The aims of this research was to analyze the implementation of the team teaching method in mathematics learning at ABC Christian High School in Sukoharjo. Mathematics aims to deepen students' understanding of God's creation and how it helps them to fulfill their calling. The research was conducted from July 18, 2016, to November 4, 2016. The subjects were the vice principal, mathematics teachers, and 29 students. This research was a case study research about the implementation of the team teaching method in mathematics learning at ABC Christian High School in Sukoharjo. The research instruments used were interview and documents. The results showed that the implications of the team teaching method were a semi full team teaching, where the teacher teaches with a division of tasks, materials, and hours in learning mathematics. The team teaching method with material distribution and teaching hours helped to overcome the teachers' situation and the learning needs of mathematics at the school, but students found it difficult to follow the teaching team's method as they were studying two different topics in a week.BAHASA INDONESIA ABSTRAK: Metode team teaching adalah metode pembelajaran yang dilaksanakan oleh lebih dari satu orang guru pada sekelompok siswa yang sama dengan cara membagi tugas, bersama-sama mengamati siswa, mengevaluasi pengajaran dan saling mendukung untuk meningkatkan hasil belajar siswa. Tujuan penelitian ini untuk mengetahui penerapan metode team teaching dalam pembelajaran matematika di SMA Kristen ABC Sukoharjo. Matematika bertujuan untuk memperdalam pengertian siswa tentang ciptaan Allah dan bagaimana pengertian itu membantu mereka untuk memenuhi panggilan mereka. Penelitian dimulai sejak tanggal 18 Juli 2016 sampai 4 November 2016. Subjek penelitian yaitu wakil kepala sekolah bidang kurikulum, guru matematika sebanyak empat orang, dan siswa sebanyak 29 siswa. Penelitian ini merupakan penelitian kualitatif studi kasus tentang penerapan metode team teaching dalam pembelajaran matematika di SMA Kristen ABC Sukoharjo. Instrumen penelitian yang digunakan adalah wawancara, observasi sebanyak tujuh belas kali dan dokumen. Hasil analisis data menunjukkan bahwa metode team teaching yang diterapkan di SMA Kristen ABC Sukoharjo merupakan semi full team teaching, dimana guru mengajar dengan pembagian tugas, materi dan jam pada pembelajaran matematika. Metode team teaching dengan pembagian materi dan jam mengajar membantu mengatasi keadaan guru dan kebutuhan pembelajaran matematika di sekolah tersebut, namun siswa kesulitan mengikuti penerapan metode team teaching karena mempelajari dua topik yang berbeda dalam seminggu.

Jenis penelitian ini adalah penelitian eksperimen semu yang menggunakan desain dua factorial. Jumlah populasinya adalah seluruh siswa kelas XI MA NW Palapa Nusantara Tahun Pelajaran 2017/2018 dengan jumlah 180 siswa. Teknik pengambilan sampel menggunakan teknik cluster random sampling dengan kelas XI IPS 4 sebagai kelas eksperimen dan kelas XI IPS 3 sebagai kelas kontrol. Instrumen pengumpulan data menggunakan angket minat belajar dan tes prestasi belajar matematika. Metode pengujian hipotesis yang digunakan Uji-t dengan taraf signifikansi 5%. Hasil penelitian ini menunjukkan bahwa: (1). nilai t hitung > ttabel yaitu thitung = 4,430 lebih besar dari pada ttabel 0.05 = 2,00484 maka H0 ditolak, yang artinya terdapat pengaruh model pembelajaran kooperatif tipe inside-outside circle (IOC) terhadap prestasi belajar matematika siswa yang memiliki minat belajar tinggi (2). nilai thitung < ttabel yaitu thitung = 1,703 lebih kecil dari pada ttabel 0.05 = 2,00484 maka H0 diterima, yang artinya tidak terdapat pengaruh model pembelajaran kooperatif tipe inside-outside circle (IOC) terhadap prestasi belajar matematika siswa yang memiliki minat belajar rendah.
The use of interactive multimedia has a big influence in the world of education, especially mathematics learning. This development research aims to produce interactive multimedia product on learning ...rectangles and triangles for grade IV to facilitate and motivate students in understanding and mastering mathematical concepts. Media development uses the Alessi & Trollip development model which has three stages, namely planning, design, and development including alpha testing and product beta testing to determine its feasibility.
