You can evaluate students' individual or group work using the following three-point rubric: Three points: unified, coherent, and age-appropriate text; subject-appropriate pictures; error-free grammar, usage, and mechanics Two points: mostly unified, coherent, and age-appropriate text; some subject-appropriate pictures; few errors in grammar, usage, and mechanics One point: text lacking unity and coherence; insufficient or inappropriate illustrations; many errors in grammar, usage, and mechanics You can ask your students to contribute to the assessment rubric by determining what makes a text unified and coherent. |

A Time Line of Word Domination From understanding our first words as a baby to the acquisition of more than 60,000 words by age 18, we must reach various milestones in both our physical and mental development. Direct students to reference books that deal with stages of physical and mental development: babbling, pointing, mimicry, questioning, experimenting, achieving syntactic maturity—and other stages. Have students create one or more visual time lines that show language milestones. Suggest that students illustrate the time line—perhaps with photographs from magazines or with photos of themselves at different stages and ages. Born to Speak? Linguists and neuropsychologists have debated the question of whether language is an inborn, genetically preprogrammed behavior or a learned response. Ask students to read reports about research into this debate. Students should look for sources that discuss, in lay terms, the following kinds of studies:

"Baby Talk: How Infants Learn Language" Rick Weiss, Washington Post Health magazine, March 4, 1997 This article explores how parents sing and coo to their babies as instinctive language-teaching techniques, and studies the possibility that babies learn language even before they are born! |

Click on any of the vocabulary words below to hear them pronounced and used in a sentence.
Context: At six weeks, the voice box is disengaged.
Context: Babbling, repeating syllables over and over, is a workout for the vocal cords.
Context: It's an imperfect form of communication.
Context: Words are joined by a definite set of rules--a primitive grammar.
Context: This kind of mimicry has a serious purpose. |

This lesson plan may be used to address the academic standards listed below. These standards are drawn from Content Knowledge: A Compendium of Standards and Benchmarks for K-12 Education: 2nd Edition and have been provided courtesy of theMid-continent Research for Education and Learningin Aurora, Colorado. Grade level: 6-8 Subject area: life science Standard: Understands the genetic basis for the transfer of biological characteristics from one generation to the next. Benchmarks: Knows that the characteristics of an organism can be described in terms of a combination of traits; some traits are inherited and others result from interactions with the environment. Grade level: 6-8 Subject area: life science Standard: Understands how species depend on one another and on the environment for survival. Benchmarks: Knows that behavior is one kind of response an organism may make to an internal or environmental stimulus, and may be determined by heredity or from past experience; a behavioral response requires coordination and communication at many levels including cells, organ systems and whole organisms. Grade level: 9-12 Subject area: technology Standard: Understands the nature of scientific knowledge. Benchmarks: Knows that because all scientific ideas depend on experimental and observational confirmation, all scientific knowledge is, in principle, subject to change as new evidence becomes available; in areas where data, information or understanding is incomplete, it is normal for scientific ideas to be incomplete, but this is also where the opportunity for making advances may be greatest. Grade level: 6-8 Subject area: behavioral studies Standard: Understands that interactions among learning, inheritance, and physical development affect human behavior. Benchmarks: Understands that all behavior is affected by both inheritance and experience. Grade level: 6-8 Subject area: behavioral studies Standard: Understands that interactions among learning, inheritance, and physical development affect human behavior. Benchmarks: Understands that the level of skill a person can reach in any particular activity depends on a variety of factors (e.g., innate abilities, amount of practice, the use of appropriate learning technologies). Grade level: 6-8 Subject area: behavioral studies Standard: Understands that interactions among learning, inheritance, and physical development affect human behavior. Benchmarks: Understands that even instinctive behavior may not develop well if a person is exposed to abnormal conditions. |
