COGNITIVE DEVELOPMENT

Sensorimotor Stage (Infancy)

Pre-Operational Stage (Toddler to Early Childhood)

Concrete Operational Stage (Elementary)

Formal Operational Stage(Adolescence)

COGNITIVE DEVELOPMENT

Sensorimotor Stage (Birth – 2 yrs old)(Infancy)

In this period, intelligence is demonstrated through motor activity without the use of symbols.

Knowledge of the world is limited (but developing) because its based on physical interactions and

experiences. Children acquire object permanence at about 7 months of age (memory). Physical

development (mobility) allows the child to begin developing new intellectual abilities. Some

symbolic (language) abilities are developed at the end of this stage.

COGNITIVE DEVELOPMENT

Pre-Operational Stage (2 – 7 yrs old)(Toddler to Early Childhood)

In this period (which has two substages), intelligence is demonstrated through the use of symbols, language use matures, and memory and imagination are developed, but thinking is

done in a nonlogical, nonreversible manner. Egocentric thinking predominates

Can Not Think Of More Than One Thing At A Time!

PRE-OPERATIONAL STAGE

PK through 2nd GradeCentration

Tendency to Focus on One Aspect of a Situation and Neglect the Other Aspects

Focusing on Color Rather Than ShapeWhen Grouping Blocks or Other Shapes

PRE-OPERATIONAL STAGE

PK through 2nd GradeLack Conservation

Quantity, Length or Number of Items is unrelated to the arrangement or

appearance of items.

Nickel is more than a DimeBecause of its Size

COGNITIVE DEVELOPMENT

Concrete Operational Stage (7-11 yrs old)(Elementary)

In this stage (characterized by 7 types of conservation: number, length, liquid, mass, weight, area, volume), intelligence is demonstrated through

logical and systematic manipulation of symbols related to concrete objects. Operational thinking

develops (mental actions that are reversible). Egocentric thought diminishes.

Conservation & Reverse Thinking With Concrete Objects!

physical transformation.A Stack versus a Row of Coins

CONCRETE OPERATIONAL STAGE

2nd – 6th GradeClassification

When a child can name and identify sets of objects

according to their appearance, size or other characteristic.

CONCRETE OPERATIONAL STAGE

2nd – 6th GradeReversibility

Objects can be Changed and thenReturned to their Original State

Fact Families4 + 5 = 9 9 – 5 = 4

COGNITIVE DEVELOPMENT

Formal Operational Stage (11+ years old)

(Adolescence)In this stage, intelligence is demonstrated

through the logical use of symbols related to abstract concepts. Early in the period there is a

return to egocentric thought.

Only 35% of high school graduates in industrialized countries obtain formal

operations; many people do not think formally during adulthood.

C017-PROBABILITY AND STATISTICS

The Teacher Understands Concepts Related to Probability and Statistics

and Their Applications.

PROBABILITY

Probability is the likelihood or chance that something is the case or that an event will occur. Probability theory is used extensively in such areas of study as mathematics, statistics, finance, gambling, science, and philosophy to draw conclusions about the likelihood of potential events and the underlying mechanics of complex systems.

PROBABILITY

In mathematics, a probability of an event A is represented by a real number in the range from 0 to 1 and written as P(A).

An impossible event has a probability of 0, and a certain event has a probability of 1.

Outcome = any possible result Event = group of outcomes Combinations= list of all possible

outcomes
