What do you mean by concrete representational abstract?
The Concrete – Representational – Abstract (CRA; also known as Concrete – Semiconcrete – Abstract) instructional strategy combines effective components of both behaviourist (direct instruction) and constructivist (discovery-learning) practices (Sealander, Johnson, Lockwood & Medina, 2012; Mercer & Miller, 1992).
How are concrete representations used to model problems?
Representational: In this stage, the teacher transforms the concrete model into a representational (semi-concrete) level, which may involve drawing pictures; using circles, dots, and tallies; or using stamps to imprint pictures for counting. In other words, this is the “seeing” stage, using representations of the objects to model problems.
What is the concrete representation of a device?
Observable's patented device allows for the establishment and maintenance of a concrete representation of normal device behavior, so that threats can be accurately and concisely identified as deviations from legitimate device behavior.
Which is the first stage of concrete representation?
The first step is called the concrete stage. It is known as the “doing” stage and involves physically manipulating objects to solve a math problem. The representational (semi-concrete) stage is the next step. It is known as the “seeing” stage and involves using images to represent objects to solve a math problem.
