Document Summary

General objective: at the end of the unit trainees will be able to describe human development: introduction to human development. Reflection: start the lesson by review questions from their previous experience. Development vs growth: we use these two terms interchangeably. More often we use growth to mean an increase in body size. Average growth rate during prenatal stage of development is shown below. At 4 weeks the embryo is one- fifth of an inch. At 8 weeks the embryo is 1 inch. At 28 weeks the fetus is 16 inches. At 38 weeks the fetus is 20 inches. Development is a more general term indicating changes physically, mentally and socially. It also, explains possible causes of changes in all areas. Example: motor development: 2 months an infant raises his head, 4-7months shows improvement in hand and eye coordination. 7 months_____ can sit up and stand up holding or a chair: development is irreversible. It does not switch back and forth.
