Kruteskii's work on the mathematical abilities of school children is a seminal work on the nature of mathematical ability. However, the task of developing methods for the practical application of his work is still a significant problem in mathematics education. The authors have developed a practical application of Kruteskii's approach to the…

This article reports the development and refinement of science and mathematics integrated activities for middle school students. The expectations of the National Council of Teachers of Mathematics that students develop an understanding of mathematics and an ability to apply it gave birth to these activities. The expectations of the National…
