Health and Sickness
1. Middle childhood is a time of steady growth and few serious illnesses, thanks to genes and medical advances.
2. Physical activity aids health and joy. However, current social and environmental conditions make informal neighbourhood play scarce, school physical education less prevalent, and sports leagues less welcoming.
3. Childhood obesity and asthma are increasing worldwide. Although genes are part of the cause, public policies (e.g., food advertising, pollution standards) and family practices also have an impact.
Cognition in Middle Childhood
4. According to Piaget, middle childhood is the time of concrete operational thought, when egocentrism diminishes and logical thinking begins. School-
5. Vygotsky stressed the social context of learning, including the specific lessons of school and learning from peers and adults. Culture affects what children learn and how they learn.

7. Memory begins with information that reaches the brain from the sense organs. Then, selection processes allow some information to reach working memory. Finally, long-
8. Selective attention, a broader knowledge base, logical strategies for retrieval, and faster processing advance every aspect of memory and cognition. Control processes, including metacognition, are crucial.
Language Advances
9. Language learning advances in many practical ways, including expansion of vocabulary and understanding of metaphors.
10. Children excel at pragmatics, often using one code with their friends and another in school. Many children become fluent in the school language while speaking their first language at home.
Teaching and Learning
11. Experts agree that primary education should be universal. Reading is assessed internationally with the PIRLS, and math and science with the TIMSS. On both, children in East Asia excel.
12. In Canada, where education is a provincial/territorial responsibility, the Pan-
13. IQ tests are designed to quantify intellectual aptitude. Most such tests emphasize language and logic and predict school achievement. Critics contend that traditional IQ tests assess too narrowly because people have multiple types of intelligence.
14. Achievement tests measure accomplishment, often in specific academic areas. Aptitude and achievement are correlated, both for individuals and for nations.
Children with Special Needs
15. Many children have special educational needs. Among the more common causes are attention deficit hyperactivity disorder (ADHD), in which children have problems with inattention, impulsiveness, and overactivity; bipolar disorder, characterized by marked mood swings; specific learning disorders; and autism spectrum disorder.
16. All special needs are partly genetic, but family and school factors can make the problems better or worse. Treatments include medication, targeted education, and family training—
