Early algebra: Repeating pattern and structural thinking at foundation phase

Algebra , Computer Algebra , and Mathematical Thinking

Mathematical symbolism in general—and symbolic algebra in particular—is among mathematics’ most powerful intellectual and practical tools. Knowing mathematics well enough to use it effectively requires a degree of comfort and ease with basic symbolics. Helping students acquire symbolic fluency and intuition has traditionally been an important, but often daunting, goal of mathematics education. ...

Crowding by a repeating pattern.

Theinability to recognize a peripheral target among flankers is called crowding. For a foveal target, crowding can be distinguished from overlap masking by its sparing of detection, linear scaling with eccentricity, and invariance with target size.Crowding depends on the proximity and similarity of the flankers to the target. Flankers that are far from or dissimilar to the target do not crowd i...

Early Islamic Architecture and Structural Configurations

Islam spread rapidly after its founding, encompassing much of North Africa, the Middle East, and Southeast Asia. The art of this vast region draws its distinctive character both from Islam itself and from the diverse cultural traditions of the world’s Muslims. Because Islam discouraged the use of figurative images, particularly in religious contexts- unlike Christian art- Islamic artists develo...
