Articulated science teaching and balanced emphasis

The set of scientific thinking tools described is based on dramatized, exaggerated patterns of logical structures. What these patterns have in common is an overall invariance relationship that makes something true even though the details may differ in different situations¿ and a knowledge of that relationship leads to simple solutions of apparently complex problems. Articulated science teaching is defined as a method of getting the invariance concept across to the student by using selected puzzles and games as exercises in logical thinking. The end result should be to improve rational reasoning ability both in science and in everyday life.
