摘要：It has been shown that mathematics achievement among K-12 students can be improved through quality after-school programs. At the same time, university mathematicians are being encouraged to partner with K-12 schools to improve teaching and learning in mathematics, and after-school programs provide a perfect context for that partnership. Yet few such partnerships exist. This study is a description of extracurricular activities in mathematics for high school students provided by universities and high schools in the Sumy region of the Ukraine, and an exploration of the cooperation between university faculty and high school faculty in providing those activities. In addition, evidence of student and parent satisfaction with those activities is presented. This study provides a positive model for cooperation between universities and high schools for the benefit of all students.
