Bischöfliches Willigis Gymnasium is a general upper secondary school in the city of Mainz in the federal state Rheinland-Pfalz in West-Germany near the metropolis Frankfurt. This is a prosperous agricultural and industrial part of Germany with international orientation due to the closeness of the bank and trade centre of Frankfurt. The Bischöfliches Willigis-Gymnasium is one of two last pure boys' schools in Germany founded as a Catholic private school. After long years of a co-educational paradigm the special needs and efforts for boy-focused pedagogy are realized by research and guideline of the pedagogic practise of the school. Consequently, the education is based on the one hand, on the encouragement and development of boy-specific potencies, on the other hand, on the compensation of gender-specific weaknesses. Therefore, one of the school's focus is musical education. The clientele arises from the city as well as from the countryside. The school participates in a governmental programme for reduced school time, which means that the students have their final secondary school examinations in Grade 12 which is a general qualification for university entrance. With a staff of almost 100 teachers the Bischöfliches Willigis-Gymnasium offers a broad curriculum to its 1000 students including music, art, science subjects, mathematics, informatics and several foreign languages (English, French, Spanish, Latin) and is committed to adopting new methodologies for the improvement of the educational experience of our students. Thus, our students participate successfully in annual national competitions with outstanding results in sciences and maths. Internationally, the opportunity of interdisciplinary project learning has been established and has been supported by many international Comenius and Erasmus plus projects so far. Also, the digital equipment for the international exchange in the project is provided by various media (smartboards, internet, Ipads) used by our students and teachers in class.
