Interdisciplinary relations in teaching of programming
Vladimír Jehlička · 2010
The presented article describes one of the potential system approaches to teaching of programming. The focus is given on the interdisciplinary interconnection between physics, informatics and mathematics. First, a simple analysis of the researched process is carried out - that means the decomposition of the light into a colour spectrum on one side and the additive composition of colours on the other side. This is followed by a mathematical description of the composition of colours from three basic components - red, green and blue - on the screen of the computer monitor. The numerical code of the resulting colour is expressed in the binary, hexadecimal and decimal numerical systems. The final part of the paper presents a simple program which enables using a computer monitor for an analysis of the additive composition of colours. It simultaneously demonstrates also advantages and disadvantages of expressing the numerical code of the composed colour in various numerical systems.
