А FAMILY TREE AND THE BINARY NUMBER SYSTEM
The article describes an example of project and research activity of students, which widely use interdisciplinar y connections of informatics with biology, mathematics, history, drawing. A new way of building a family tree is given, its practical creation in the graphic editor is considered. It’s described how this method for constructing a family tree allows to visualize some aspects of the binary number system.
Keywords: project, project activity, research activity, interdisciplinary connections, biology, family tree, how to build a family tree, tree cut down, number system, binary number system.
LESSONS OF COMPUTER SCIENCE
