Cultural Patterns of Growth
Influences
*
Should hormones be used to make short children grow?
*
Ask: What do you think? What contributed to your answer? In all instances? Under what conditions? Whose decision is it?
Artificial Hormones: Points to Consider
*
Growth hormones are released from the anterior pituitary gland. Pituitary adenomas can produce excess growth hormones. This can cause abnormal growth patterns called acromegaly in adults and gigantism in children. Excess growth hormones can increase blood pressure and blood sugar.
Individuals with resistance to growth hormones or known pituitary disease may not produce enough growth hormones. In children this can cause short stature. In adults, insufficient can lead to changes in muscle mass, cholesterol levels, and bone strength.
Nutritional Benefits
Benefits of Adequate Nutrition
Relationship to social and emotional functioning
*
Test of the speed and accuracy of response on problem-solving tasks given to children who did or did not eat breakfast skipping breakfast had an adverse influence on their performance on the tests (Pollitt et al. 1991)
Consequences of Inadequate Nutrition
Undernutrition is implicated in more than half of all child deaths worldwide
Undernourished children

Obesity
*
In the United States over the past 20 years, obesity has increased by 54 percent in 6 to 11 year old children and by 39 percent among 12 to 17 year olds.
Costs of Childhood Obesity
*
In fact, some scientists believe that an epidemic of obesity may be leading to a decline in life span in the U.S.
Figure 9-2 Obesity in Children
Obesity in children from ages 6 to 12 has risen dramatically
over the past three decades.
The other side of “fat”
*
Balanced Diet?
Recent studies have found that the diet of children is almost the opposite of that recommended by the U.S. Department of Agriculture,
a situation that can lead to an increase in obesity.
The typical 10-year-old is 10 pounds heavier
than a decade ago.

Asthma
About asthma
*
Asthma brings different challenges for school-age kids. A child might feel embarrassed using an inhaler at school, for example, or worry about having an asthma attack in front of friends.
There are two main types of medications available to treat asthma. Inhaled anti-inflammatories or "controller" medicines are used to prevent asthma flare-ups.
During an asthma attack, the muscles around the airways tighten, or "spasm" (like when you make a fist) and the lining inside the airways swell or thicken, and get clogged with lots of thick mucous. This makes the airways much skinnier than usual so it is harder to move air in and out of the air sacs. This makes it hard to breathe!
Other Health Risks
*
Figure 9-5 Injury Death Rates by Age
During middle childhood, the most frequent causes of accidental death are transportation-
related. Why do you think transportation-related deaths soar just after middle childhood? (Source: Borse et al., 2008.)

Sensory Difficulties: Visual, Auditory, and Speech Problems
*
Do you see what I see?
Difficulties in seeing
*
Visual impairment happens when there is a problem with one or more parts of the eyes or the parts of the brain needed to process the images sent from the eyes.
Although many people think blindness means a person can't see at all, this isn't always true. Some children who are considered blind can still see a little light or shadows, but they can't see things clearly.
The behaviors of children with CVI reflect their adaptive response to the characteristics of their condition
Say what?
*
People with hearing impairments communicate in a variety of ways, depending on several factors: amount of residual hearing, type of hearing impairment, language skills, age when the impairment began, speech abilities, speech-reading skills, personality, intelligence, family environment, and educational background.
Children Who Do Not Hear
*
A severe speech-language impairment may result in one or more of the following:
I Am Talking to YOU!
Definition
*
The language impairment may be manifested by one or more of the following components of language: morphology, syntax, semantics, phonology, and pragmatics;
Stuttering

Family dynamics
Learning Disabilities
Discrepancies Between Achievement and Capacity to Learn
*
LD is a disorder that affects people's ability to either interpret what they see and hear or to link information from different parts of the brain. These limitations can show up in many ways: as specific difficulties with spoken and written language, coordination, self control, or attention. Such difficulties extend to schoolwork and can impede learning to read, write, or do math.
The Brains of Children With ADHD
The brains of children with ADHD (in the top row) show less thickening of the cortex compared to the brains of typical children at the same age.

The Basic Definition in Individuals with Disabilities Education Act (IDEA)
“Learning disability” = umbrella term
*
DISORDERS INCLUDED- Such term includes such conditions as perceptual disabilities, brain injury, minimal brain dysfunction, dyslexia, and developmental aphasia.
DISORDERS NOT INCLUDED- Such term does not include a learning problem that is primarily the result of visual, hearing, or motor disabilities, of mental retardation, of emotional disturbance, or of environmental, cultural, or economic disadvantage.
Developmental Reading Disability
Dylexia affects 2 to 8 percent of elementary school children
*
When you think of what is involved in the "three R's" -reading, 'riting, and 'rithmetic- it's astounding that most of us do learn them. Consider that to read, you must simultaneously:
Focus attention on the printed marks and control eye movements across the page
Recognize the sounds associated with letters
Understand words and grammar
Build ideas and images
Compare new ideas to what you already know
Store ideas in memory
Developmental Writing Disabilities
Writing involves several brain areas and functions (dysgraphia)
*
For example, a child with a writing disability, particularly an expressive language disorder, might be unable to compose complete, grammatical sentences
Developmental Arithmetic Disability
*
Problems with number or basic concepts are likely to show up early
Disabilities that appear in the later grades are more often tied to problems in reasoning.

ADHD Treatment Controversy
Ritalin or Dexadrine reduce activity levels in hyperactive children and are routinely prescribe
*
Overprescribing Ritalin?
The number of children being given drugs for psychological disorders has increased significantly over the last decade.
(Source: U.S. Surgeon General, 2000.)
*
Are there other treatments for ADD/ADHD?
Treatments
*
Keeping Children Fit
*
Make exercise fun. In order for children to build the habit of exercising, they need to find it enjoyable. Activities that keep children on the sidelines or that are overly competitive may give children with inferior skills a lifelong distaste for exercise.
Be an exercise role model. Children who see that exercise is a regular part of the lives of their parents, teachers, or adult friends may come to think of fitness as a regular part of their lives, too.
Gear activities to the child's physical level and motor skills. For instance, use child-size equipment that can make participants feel successful.
Encourage the child to find a partner. It could be a friend, a sibling, or a parent. Exercising can involve a variety of activities, such as roller skating or hiking, but almost all activities are carried out more readily if someone else is doing them too.
Start slowly. Sedentary children—those who aren't used to regular physical activity—should start off gradually. For instance, they could start with 5 minutes of exercise a day, 7 days a week. Over ten weeks, they could move toward a goal of 30 minutes of exercise 3 to 5 days a week.
Urge participation in organized sports activities, but do not push too hard. Not every child is athletically inclined, and pushing too hard for involvement in organized sports may backfire. Make participation and enjoyment the goals of such activities, not winning.
Don't make physical activity, such as jumping jacks or push-ups, a punishment for unwanted behavior. Instead, schools and parents should encourage children to participate in organized programs that seek to involve children in ways that are enjoyable.
Provide a healthy diet. Children who eat nutritiously are going to have more energy to engage in physical activity than those who have a diet heavy in soda and snack foods.

INTELLECTUAL DEVELOPMENT
*
What are advances and limitations, in thinking during childhood?
Approaches
*
Intellectual Development: Piaget
Concrete operational stage
*
Routes to Conservation
After being told that the two cars traveling on Routes 1 and 2 start and end their journeys in the same amount of time, children who are just entering the concrete operational period still reason that the cars are traveling at the same speed.
Later, however, they reach the correct conclusion: that the car traveling the longer route must be moving at a higher speed if it starts and ends its journey at the same time as the car traveling the shorter route.
*
How does preoperational thought emerge?
Shift from preoperational thought to concrete operational thought does not happen overnight
*
Conservation Training
Rural Australian Aborigine children trail their urban counterparts in the development of their understanding of conservation; with training, they later catch up. Without training,
around half of 14-year-old Aborigines do not have an understanding of conservation.
What can be concluded from the fact that training influences the understanding of
conservation?
(Source: Based on Dasen, Ngini, & Lavallee, 1979.)
Piaget Was Right…Piaget Was Wrong
*
Information Processing
Increasing ability to handle information
*
Thinking about Memory: Metamemory
*
Can children be trained to be more effective in use of control strategies?
*
Vygotsky's Approach
Cognitive advances occur through exposure to information within zone of proximal development (ZPD)
*
WHAT IS IT? Reciprocal teaching refers to an instructional activity that takes place in the form of a dialogue between teachers and students regarding segments of text. The dialogue is structured by the use of four strategies: summarizing, question generating, clarifying, and predicting. The teacher and students take turns assuming the role of teacher in leading this dialogue.
LANGUAGE DEVELOPMENT
*
Mastering the Mechanics of Language in Middle Childhood
*
Assertions about early grammar acquisition: Grammatical elements are innate; Syntactic rules are used in early “sentences;” Grammar learning is implicit.
Semantics = meaning of morphemes and words. Syntax = grammar conveyed through word order. Grammar = syntax + inflectional morphology. Two ways linguistic information stored:
Lexicon = individual “words” & information;
Rules = generalized procedures.
Two types of grammatical information: categories in lexicon; terminal elements (e.g. N, V), non-terminal elements (e.g. NP, VP); “rewrite” rules
Grammar = arranging elements using rules; Semantics is irrelevant.
Chomsky (1959) demolished behaviourism:
language is unpredictable;
language is creative.
Use a special kind of rule:
requires competence-performance distinction;
Gold's theorem – language unlearnable.
Psychologists – initially sort evidence support linguists’ claims, but increasing conflict.
Examine two proposals which arose from the linguistic perspective: Grammatical elements are innate.
Syntactic rules are used in early “sentences”.
Pinker (1984):
grammatical elements are innate;
grammar acquisition involves mapping words onto these elements .
Mapping achieved via semantics:
learn very general semantic categories = thematic roles (e.g. theme, goal);
innate linking rules maps roles to elements.
Bowerman (1990):
theory predicts some verbs hard to learn;
if theme maps to subject easy (e.g. fall), if elsewhere (e.g. lose) hard;
but, acquired at same time.
Braine (1988):
if learn thematic roles why not grammatical units? – Semantic Assimilation Theory.
Construct grammatical units from semantics.
Early language is agrammatical.
Nouns = things, adjectives = attributes, verbs = actions – but McShane (1991):
abstract nouns (e.g. sleep, truth, love);
verbs “states” not actions (e.g. want, think, like).
Can not be semantic analysis alone (e.g. states are verbs expect “I hungries”).
Where do grammatical units come from?
Innate principles are not necessary or even useful.
Semantics may also be of little help.
Probably learn through patterns in language – syntactic + morphological:
turns Gold's theorem on its head;
false assumptions – e.g. learning is not rule based induction.
Early Grammar
Up to three years:
language use inflexible (Tomasello, 2000);
lexically based around individual verbs (Pine & Lieven, 1997);
no grammatical rules – acquisition statistically.
No grammar module at birth:
context & social factors crucial (Messer, 2000);
develops during childhood (e.g. Kim et al., 1997)
Metalinguistic Awareness
One of most significant developments in middle childhood is children's increasing understanding of their own use of language
*
In early years learn and comprehend these rules implicitly, during middle childhood come to understand them more explicitly
Help achieve comprehension when information is fuzzy or incomplete

The Diversity of Language Other Than English Spoken in the United States
These figures show the number of U.S. residents over the age of five who speak a language other than English at home. With increases in the number and variety of languages spoken in the United States, what types of approaches might an educator use to meet the needs of bilingual students?

Educational Trends in the Next Millennium

Cultural Assimilation or Pluralistic Society?
Multicultural education developed in part as a reaction to a cultural assimilation model in which the goal of education was to assimilate individual cultural identities into a unique, unified American culture
Figure 9-13 The Changing Face of America
Current projections of the population
makeup of the United States show that
by the year 2050, the proportion of non-
Hispanic whites will decline as the proportion
of minority group members increases.
What will be some of the impacts of changing
demographics on social workers?
(Source: U.S. Census Bureau, 2000
As the U. S. population has become more diverse, elementary schools have also paid increased attention to issues involving student diversity and multiculturalism. And with good reason:
