У статті розглядається міжпредметна компетентність як невід’ємна складова професійної компетентності. Названі функції компетентностей у навчанні. Наведені приклади суміжних начальних дисциплін з елементарною математикою та відповідні теми занять. Сформульоване означення та класифікація міжпредметних завдань, наведено приклади.
The article focuses on interdisciplinary competence as a separate component of a future teacher of mathematics professional competence. The functions of competencies in education are enumerated. The attention is drawn to the fact that interdisciplinary competence is formed at the junction of two or more subjects. The examples of the related disciplines of elementary mathematics and the corresponding topics are given. The article emphasizes that completing interdisciplinary tasks directly affects interdisciplinary competence forming. The above mentioned tasks should be an approved curriculum construction of two or more subjects. It also should be worked out when general educational goals as well as the goals determined by a particular subject are taken into account. The examples of interdisciplinary tasks classifications are given; the examples of interdisciplinary problems in elementary mathematics of linear algebra, analytic geometry, mathematical analysis, computer science are also displayed. The software training is offered. The author states that it allows to solve a wide range of mathematical problems of different content and different difficulty levels and is aimed at using it in teaching mathematics and other subjects of natural and mathematical cycle.
