To acquire knowledge, thought is a fundamental necessity -It must be "thought about" before any new ideas can be formulated (e.g., a student who is learning English as a second language must be competent in his primary native language before he can "think" or understand new concepts in another language) -Initial emergence of language and thought are separate from each other, until about the age of 3 when a transition takes place in the child from the external to the internal -Children practice private speech (self-talk) to become more competent ---The use of private speech helps children to self-regulate through organizing, guiding, and controlling their behavior ---Private speech is responsible for all higher levels of mental functioning Noam Chomsky Language Acquisition -Language learning is innate -Chomsky believes that children are prewired to learn language and that infants have a language acquisition device (LAD) built-in neurologically so that they can intuitively understand grammar -There is a critical period when children find it easy to learn language Language development milestones: Infant (0-12 months) -Early vocalizations are spontaneous sounds of cooing (vowels) or crying -Then babbling sounds (phonemes) begin with sounds more like patterned speech with consonant-vowel strings ("da-da-da-da")

The slope of the blue curve measures the plane's rate of descent. the unit of measurement for the slope of the curve is feet per minute. at point a, the slope of the curve is -2,500, which means that the plane is descending at a rate of 2,500 feet per minute. at point b, the slope of the blue curve is , which means that the plane is at a rate of feet per minute

Further explanation

As you are measuring altitude against time, the slope of the curve measures the plane's rate of climb or descent.

At t = 0, the plane is at an altitude of 11 kilometer. It is descending all the time until at t = 10 the plane reaches ground level.  At both points the plane is descending.  Whereas at point A, the tangent line shows the rate of descent as 2 km over 2 minutes = 1 km per minute.

At point B, the tangent line shows the rate of descent as 2 km over 4 minutes = ½ km per minute.
