    2. Puberty The Biological Explosion Teaching Tip: Before students begin to read this chapter, have them write down thoughts about their own experiences during adolescence (physical, cognitive, and social/emotional). Compile their responses (no names attached) and use this list as a reference for the next two chapters. How typical were their experiences?Teaching Tip: Before students begin to read this chapter, have them write down thoughts about their own experiences during adolescence (physical, cognitive, and social/emotional).

    3. What Is Adolescence? Transitional period between childhood and adulthood G. Stanley Hall Proposed adolescence as separate stage Marked by Sturm and Drang Sigmund Freud Genital stage Anna Freud Turbulent period Current theorists Reorganization, not necessarily turbulent or stressful Teaching Tip: Divide the class into two groups and have the groups support or dispute the following statement: Adolescence is a time of emotional and physical upheaval and dramatic change for all adolescents. Teaching Tip: Divide the class into two groups and have the groups support or dispute the following statement: Adolescence is a time of emotional and physical upheaval and dramatic change for all adolescents.

    4. What Is Adolescence? Three Phases of Adolescence Early adolescence (11 or 12 – 14 years) Middle adolescence (14 – 16 years) Late adolescence (16 – 20 years) Tweens Earlier age for adolescence Emerging Adulthood Later age for adolescence Teaching Tip: Have students reflect on the various phases presented in this section. In their opinion, are these valid phases? Are there other phases that should be included, deleted, or changed?Teaching Tip: Have students reflect on the various phases presented in this section. In their opinion, are these valid phases? Are there other phases that should be included, deleted, or changed?

    5. What Is Puberty? Puberty is a biological concept Attaining sexual maturity and ability to reproduce Puberty is controlled by feedback loop Hypothalamus – Pituitary gland – Gonads – Hormones Sex hormones trigger development of Primary sex characteristics Secondary sex characteristics Teaching Tip: Nursing & Health: Have students dig a little deeper into the physical changes that occur during adolescence. What starts these changes? At what point are these changes complete? Students may share their findings in a class discussion.

    6. What Happens During the Adolescent Growth Spurt? Girls begin their growth spurt earlier than boys Reach peak growth in height about 2 years after spurt began Continue to grow at a slower rate for another 2 years Weight spurt begins about 18 months after height spurt Boys catch up to girls and eventually are taller and heavier Body shapes differ by sex Boys have broader shoulders Girls gain almost twice as much fatty tissue

    7. Spurts in Growth Figure 14.1 Spurts in Growth. Girls begin the adolescent growth spurt about 2 years earlier than boys. Girls and boys reach their periods of peak growth about 2 years after the spurt begins – at about 12 and 14 years, respectively.Figure 14.1 Spurts in Growth.

    8. Growth Curves for Height and Weight Figure 14.2 Growth Curves for Height and Weight. Girls are taller and heavier than boys from about age 9 or 10 until about age 13 since their growth spurt occurs earlier. Once boys begin their growth spurt, they catch up with girls and eventually become taller and heavier. Source: Kuczmarski et al. (2000, Figures 9-12).Figure 14.2 Growth Curves for Height and Weight.

    9. What Happens During the Adolescent Growth Spurt? Asynchronous Growth Exception to proximodistal growth Hands and feet mature before arms and legs Reversal of cephalocaudal growth Legs reach peak growth before shoulders and chest Secular Trend May have reached genetic potential In industrialized countries Middle-upper-class families – stopped growing taller Poorer families continue to make gains Nutrition and health care are factors Truth or Fiction Revisited American adolescents are growing taller than their parents. (TRUE and FALSE) Teaching Tip: Parenting & Family Studies: Have students interview their extended family members about the timing of puberty and their current height. Can they detect any patterns that are consistent with the secular trend?Truth or Fiction Revisited American adolescents are growing taller than their parents.

    10. Are We Still Growing Taller Than Our Parents? Figure 14.3 Are We Still Growing Taller Than Our Parents? Twentieth-century children grew more rapidly and grew taller than children in preceding centuries. However, it seems that children from affluent families are no longer growing taller than their parents. But children from the lower part of the socioeconomic spectrum are still doing so. Source: Tanner (1989).Figure 14.3 Are We Still Growing Taller Than Our Parents? Twentieth-century children grew more rapidly and grew taller than children in preceding centuries.

    11. Pubertal Changes in Boys Average age of 11˝ – first visible sign of puberty Growth of testes accelerates testosterone production Body hair growth Voice deepens – growth of larynx Acne Increase in penile erections Nocturnal emissions Gynecomastia – enlargement of breasts About age 20 to 21 – puberty ends Epiphyseal closure Teaching Tip: Nursing & Health: Have students find out more about gynecomastia. They should investigate whether any new treatments are available to adolescent boys who have that condition. Teaching Tip: Parenting & Family Studies: The physical changes associated with puberty can be alarming to both boys and girls. What advice do students think that parents should give adolescents to help ease the fear and answer the questions associated with puberty?Teaching Tip: Nursing & Health: Have students find out more about gynecomastia.

    12. Pubertal Changes in Girls Increased estrogen production Stimulates breast buds Promotes fatty tissue in hips and buttocks Production of androgen Simulates pubic and underarm hair growth Estrogen causes labia, vagina, and uterus to develop Androgens cause clitoris to develop

    13. Pubertal Changes in Girls Menarche May begin as early as 9 or as late as 16 Body weight may trigger menarche Hormonal Regulation of Menstrual Cycle Ovulate 12 to 18 months after menarche Average menstrual cycle is 28 days May be irregular during first 2 years Psychological Impact of Menarche Rite of passage Educated and prepared – more positive Truth or Fiction Revisited Girls are fertile immediately after their first menstrual period.

Teaching Tip: Social Work & Counseling: What impact do parental attitudes have on how a girl accepts the onset of menstruation and the other changes associated with puberty? If possible, have students interview women of different generations to see how their experiences differ. Discuss their findings in class.Truth or Fiction Revisited Girls are fertile immediately after their first menstrual period.

    14. The Decline in Age at Menarche Figure 14.4 The Decline in Age at Menarche. The age at menarche has been declining since the mid-1800’s among girls in Western nations, apparently because of improved nutrition and health care. Menarche may be triggered by the accumulation of a critical percentage of body fat. Source: Tanner (1989).Figure 14.4 The Decline in Age at Menarche.
