Middle Childhood: Body, Mind, and School

This is Unit Seven, part three, on learning disorders, ADHD, disability law, language, and how reading is taught. Part two closed on mindset theory, weighed with both halves. Part three opens with specific learning disorders, then turns to language and reading. Carry one question through this part: what does the evidence actually support about learning differences and teaching? Myths about letter reversals, sugar and bilingual brains all get tested. At the entry on the reading wars, the part shows a case where the record is lopsided, and popularity is not evidence. By the end you will be able to define specific learning disorder and its three common forms. To name ADHD's presentations and correct two myths about it. To match three disability laws to what each does. To state what the research supports in the reading wars. And to name four programme types for English learners.

Two entries on specific learning disorders, and on a common myth about dyslexia.

Specific learning disorders.

HGD 0958 Specific Learning Disorders

A learning disability is difficulty in a specific academic area that is not due to intellectual, physical or sensory impairment; the current diagnostic manual calls it specific learning disorder, a neurodevelopmental disorder. Dyslexia is difficulty with reading, affecting about seven percent of people, a rate that varies by country and writing system, from about eleven percent in Nigeria to two in Slovakia. Dysgraphia is difficulty with writing; dyscalculia, with mathematics. Diagnosis looks for difficulty that persists despite adequate teaching and targeted intervention; the older IQ-achievement gap approach lacks empirical support. Interventions help.

A common myth about dyslexia.

HGD 0959 Dyslexia and Letter Reversals

Dyslexia centres on difficulty connecting the sounds of language to the letters of words, not on seeing letters backwards. The misconception is that dyslexia means seeing letters backwards. Confusing b and d, even mirror-writing a letter, is common and typical among beginning readers and writers.

Three entries on ADHD: how common it is, how it presents and is treated, and a myth about sugar.

ADHD, and its rising diagnosis.

HGD 0960 ADHD

ADHD is a neurodevelopmental disorder of inattention, hyperactivity and impulsivity, and the CDC estimates nearly twelve percent of US children aged three to seventeen have a current diagnosis: boys at thirteen percent and girls at seven, partly because girls' symptoms are more often internal. The misconception is that rising diagnoses mean rising cases; better awareness and screening likely explain much of it.

Presentations, causes and treatment.

HGD 0961 ADHD Presentations, Causes and Treatment

ADHD has three presentations: predominantly inattentive, predominantly hyperactive-impulsive, and combined. It often persists into adulthood and can be first diagnosed there. It is not an intellectual disability, but executive-function difficulties can lower grades and raise the risk of retention and dropout; a child may be unable to sit through a lesson yet stay hyper-focused for hours on a rewarding video game. Causes include genetics tied to dopamine, preterm birth, prenatal exposures and a less-developed frontal lobe. Treatment includes stimulant and non-stimulant medication and behavioural therapy, and opinions differ on stimulants for children. The course describes treatments; it never recommends one.

Sugar and hyperactivity.

HGD 0962 Sugar and Hyperactivity

Sugar does not cause hyperactivity; a critical review of the research found the common belief to be a myth, as when parents blame a child's excitement at a birthday party on the cake rather than the party. Food additives show only a very small effect in research.

One entry on the three US laws that protect children with special learning needs.

Three laws, and what each does.

HGD 0963 Disability Law

Three US laws protect exceptional learners, children with special learning needs. Section five hundred four of the Rehabilitation Act, from nineteen seventy-three, requires accommodation in any federally funded programme. The Americans with Disabilities Act, from nineteen ninety, bars disability discrimination and extends protection to employment and public facilities. The Individuals with Disabilities Education Act guarantees a free appropriate education from birth to twenty-one, in the least restrictive environment, and every child served under it has an individualized education program, an IEP. On the exam: accommodation in a funded programme is Section five hundred four, the education guarantee is IDEA, broad protection is the ADA.

Five entries on language at school age: more words, thinking about words, harder grammar, and using language in context.

Vocabulary growth.

HGD 0964 Vocabulary Growth

Vocabulary grows dramatically in middle childhood and supports reading, language processing and even recognizing emotions in others. It grows more during the school year than in summer, a difference largest for lower-income children, and it tracks reading and family income through the amount and variety of language children hear.

Thinking about language itself.

HGD 0965 Metalinguistic Awareness

Metalinguistic awareness is thinking about language itself, which lets children grasp synonyms, words with several meanings, puns and later sarcasm, like a nine-year-old laughing at a joke that turns on duck, the bird and the action. Puns depend on noticing that one word has two meanings.

Complex grammar.

HGD 0966 Complex Grammar

Complex grammar arrives in middle childhood, including the passive voice and conditional sentences such as if it rains, we'll stay in. Grammar timing reflects the language a child hears: Northern East Cree children, whose language uses the passive often, use it much earlier than English speakers, who master it late.

Pragmatics.

HGD 0967 Pragmatics

Pragmatics is using language appropriately in social contexts, for different purposes, listeners and written forms, following hidden rules of turn-taking, eye contact and gesture. In one comparison, children with ADHD scored lower on pragmatics than typical peers but higher than children with developmental language disorder.

Code-switching.

HGD 0968 Code-Switching

Code-switching is changing forms of language within a conversation or between settings, such as speaking with peers versus teachers, or a bilingual child moving between Spanish and English in one sentence at home. Multilingual code-switching requires competence in both languages and goes with a bicultural identity; it signals skill, not confusion.

Three entries on teaching reading: three approaches, the evidence on them, and where reading stands now. The opening question is answered here.

Three ways to teach reading.

HGD 0969 Phonics and Whole Language

Phonics teaches translating letters into sounds and blending them; whole language teaches reading in natural context; balanced literacy blends the two, including memorized sight words. English maps roughly forty-four sounds onto twenty-six letters, the code phonics teaches. Reading, unlike speaking, requires explicit teaching and practice.

The payoff: the reading wars, weighed.

HGD 0970 The Reading Wars

The reading wars are the long debate over how to teach reading. Phonics teaches children to translate letters into sounds and blend them into words. Whole language holds that children learn best meeting words in real books. Balanced literacy, popular from the early two thousands, blends the two. The research record is lopsided, and it answers this part's question. The National Early Literacy Panel found that phonemic awareness and phonics knowledge predict reading, and that phonics instruction improves reading scores; a major review by Castles and colleagues agreed. Balanced literacy is often presented as the settled compromise, but the evidence most directly favours systematic phonics. The misconception is that the debate is a matter of taste: early reading difficulty predicts later problems and dropout. A method's popularity is not evidence that it works. Stating the evidence is not advice to any family or school.

Where US reading stands.

HGD 0971 Reading Proficiency

In twenty twenty-four, thirty-one percent of US fourth-graders read at or above the NAEP Proficient level, two points below twenty twenty-two. Remote learning during COVID closures cut reading and maths performance most for low-income families; high-poverty schools, students with disabilities and English learners were hit hardest.

Four entries to close the unit, on children who speak more than one language, and on how schools teach them.

Multilingual children.

HGD 0972 Multilingual Children

About twenty-six percent of US children are multilingual, compared with ninety percent in Singapore, sixty-seven in Europe and fifty-five in Canada, and they speak more than one hundred languages. Simultaneous bilinguals learn two languages from the start; sequential bilinguals learn a second later, which takes longer.

The bilingual advantage, debated.

HGD 0973 The Bilingual Advantage Debate

Claims that bilingualism improves executive function and attention are contested; reviews find the advantage inconsistent, while social benefits are uncontested. Bilingual children may have a smaller vocabulary in each language than monolingual peers, a modest challenge. Two languages neither confuse children nor reliably make them smarter.

Programmes for English learners.

HGD 0974 Programmes for English Learners

US schools use four main programme types for English learners. Immersion teaches all subjects in English, with more loss of the home language. Developmental bilingual programmes start in the home language and add English. English as a Second Language pulls students out for English classes, with no home-language support elsewhere. Two-way immersion teaches equally in two languages, to English learners and native English speakers together, and it is more effective for learning English and supports heritage and home-language retention, though access is unequal and results by subject are mixed. The choice reflects a school's goal: assimilation or multiculturalism.

Learning a second language.

HGD 0975 Second Language and the Sensitive Period

Children learn new languages more easily than adults; learners who start before about ten are often indistinguishable from native speakers, a sensitive period rather than a critical one, and in one large study grammar learning stayed strong until about seventeen or eighteen. Only about twenty percent of US children study a second language in school; most European countries require one.

Look at what you can now do. You can define specific learning disorder, and name dyslexia, dysgraphia and dyscalculia, with dyslexia a matter of sounds and letters, not reversed letters. You can name ADHD's three presentations, and correct two myths: rising diagnoses do not mean rising cases, and sugar does not cause hyperactivity. You can match the laws: Section five hundred four for accommodation, the ADA for broad protection, IDEA for the education guarantee and the IEP. You can state what the reading research supports: phonemic awareness and phonics knowledge predict reading, and the evidence most directly favours systematic phonics. And you can name four programmes for English learners: immersion, developmental bilingual, English as a Second Language, and two-way immersion. Unit Eight turns to the social world of middle childhood.
