  • The Student Lab to top
  • Development of I.Q. and the Degree of Relatedness
  • Directions:  Using the diagram, I.Q. and the Degree of Relatedness, with resources  provided by your teacher, answer the following questions with your cooperative learning leam.  Be prepared to present your answers to the whole class for discussion.
  •  
  • 1.    What do the following values mean for the correlation coefficients? (-1) (0) (+1)
  • 2.    Based on the diagram, I.Q. and the Degree of Relatedness, compare unrelated persons raised together
  •         (such as two children adopted into the same family) with monozygotic twins raised together.  How
  •         might genotype account for the correlations of I.Q. phenotype?
  • 3.    Using a variety of resources, define intelligence. Are there different types of intelligence? explain
  •  
  • 4.    What does I.Q. (intelligence quotient) measure?  How and at what age is it calculated?
  • 5.    Do you feel I.Q. tests adequately measure a person's intelligence?  What criteria is used to measure
  •        intelligence?  How is the embryological development of the brain related to the  development of I.Q.?
  • 6.    Why might the genetic correlation between parent-child be the same as for siblings? explain your
  •         answer
  • 7.    Why might dizygotic twins resemble siblings more in their genetic correlation than monozygotic twins?
  • 8.    Account for the higher correlation of I.Q. in monozygotic twins reared together than those reared
  •        apart.
  • 9.  If environmental influence is important in I.Q. development, account for the low correlation in the
  •       foster parent-child group.
  • 10. Some current studies show the hereditarian argument to have more influence on I.Q. than the
  •       environment.  Based on this diagram, what do you think influenences a person's I.Q. more: their
  •       genotype or their environment in which they are raised?  Give specific examples.

    Methods of Evaluation/Assessment to top

     Various methods may be used for assessment depending on how the activity is used by the teacher.  Written answers to questions may be turned in by each individual student or the team for evalution.  Teachers may choose to use this for an introductory activity without individual assessment but might choose to give team points for completion.
