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.
The Montessori approach emphasizes nature, creativity, and hands-on learning with gentle guidance provided by the teachers. The goal of the Montessori method is to develop a child's senses, character, practical life skills, and academic ability.
