A data model explicitly determines the structure of data. Data models are specified in a data modeling notation, which is often graphical in form. A data model can be sometimes referred to as a data structure, especially in the context of programming languages. Data models are often complemented by function models, especially in the context of enterprise models.
The Association Montessori Internationale (AMI), founded by Maria Montessori in 1929, maintains Montessori educational principles and disseminates Montessori education throughout the world.
Children learn through their senses. Montessori saw that children built on their physical experiences of the world through their senses and that by carefully designing interesting materials which the children were drawn to experiment with, she could help them extend this understanding.
