Elementary school children still face cognitive limitations: Lack adults’ broad base of knowledge. Sometimes have trouble using a particular skill of set of skilsl as part of larger problem-solving system. Cannot reason maturely about abstract hypothetical problems.

Conservation Concepts By age 10, most children understand conservation of physical quantities such as: number length area mass displaced liquid volume Copyright © 2004 The McGraw-Hill Companies, Inc. Permission required for reproduction or display. Culture and the Emergence of Conservation Concepts 1. In traditional cultures that lack formal schooling, a lag of 1-2 years is frequently found. This does not suggest their people have major cognitive deficits, and depending on the culture they may be advanced in some conservations. 2. Researchers conducting studies in other countries may encounter communication problems. 3. Cultures lacking formal schooling do not provide the same opportunities to learning about some conservation concepts or test taking. Contingent truth: Knowledge that depends on empirical observations, on information gathered through the senses. Necessary truth: Knowledge that is based on logical necessity, apart from information gathered through the senses. Copyright © 2004 The McGraw-Hill Companies, Inc. Permission required for reproduction or display. An Information-Processing Approach to Conservation Information-processing theory offers an explanation based on changes in mental procedures (rules) children follow to arrive at their solutions. Problem solvers do not consciously follow these rules. They use them implicitly. Copyright © 2004 The McGraw-Hill Companies, Inc. Permission required for reproduction or display. Classification Skills Hierarchical classification: A classification system in which items are categorized using a hierarchy of subordinate and superordinate classes. Matrix classification: A classification system in which items are categorized simultaneously along two independent dimensions, such as shape and color. Copyright © 2004 The McGraw-Hill Companies, Inc. Permission required for reproduction or display. Classification Skills Children begin to classify early in life. Not until middle childhood do they use classification effectively to organize information. Performance on classification tasks improves because they overcome centration. Elementary school children still do not entirely grasp the logical necessity of classification structures. Copyright © 2004 The McGraw-Hill Companies, Inc.

Information-Processing Abilities Memory Abilities Memory development during middle childhood involves changes in: memory capacity knowledge memory strategies metamemory Copyright © 2004 The McGraw-Hill Companies, Inc. Permission required for reproduction or display. Memory Capacity Memory capacity involves the amount of information that can be held in the various memory stores. Long-term capacity is virtually unlimited. Short-term and sensory registers both have limited capacity, which increases from early to middle childhood. The increases are best described as increases in functional capacity. Copyright © 2004 The McGraw-Hill Companies, Inc. Permission required for reproduction or display. Memory Strategies Mnemonic strategies Intentional, goal-directed behaviors designed to improve memory. Rehearsal The mnemonic strategy of repeating information over and over. Organization The mnemonic strategy of arranging information to be recalled into meaningful categories. The mnemonic strategy of creating a meaningful connection between items to be remembered, either verbally or visually. Elaboration Copyright © 2004 The McGraw-Hill Companies, Inc. Permission required for reproduction or display. Metamemory Metamemory: Knowledge about memory and memory processes. Once children realize mnemonic strategies improve recall, they are more likely to use them. Many 5- and 6-year-olds can think of only one strategy; older children think of more.

Children and adults all predict they will remember more items than they actually remember. 2. Younger children are particularly optimistic. By age 10 to 12 years predictions correlate with actual performance Copyright © 2004 The McGraw-Hill Companies, Inc. Permission required for reproduction or display.

Didactic learning experience: Situation in which a knowledgeable teacher who has already mastered a problem teaches a particular solution to a learner. Cooperative learning experience: A situation in which learners at about the same knowledge and skill interact, share ideas, and discover solutions on their own. Copyright © 2004 The McGraw-Hill Companies, Inc. Permission required for reproduction or display. Didactic learning experiences can be provided by either adults or more knowledgeable peers. Children become increasingly effective at teaching one another with age. Learning among peers is not always as effective as learning from an adult. Piaget’s theory applies more to cooperative learning situations, focusing on what happens inside the individual. Vygotsky’s theory applies more to didactic learning situations, focusing on what happens between individuals. Copyright © 2004 The McGraw-Hill Companies, Inc. Permission required for reproduction or display. Several factors facilitate cooperative learning among peers: Task should be concrete, rich in relevant information, not too complex. Information available must support at least two different conclusions. Peers must see reaching consensus as a goal. The children should know each other and have smooth system of interaction.

Broadening the Definition of Intelligence Academic intelligence: Intellectual capacity as measured by performance on tasks typically encountered in school or on standard IQ tests. Practical intelligence: Intellectual capacity as reflected in successful performance in natural, everyday, nonschool settings. Copyright © 2004 The McGraw-Hill Companies, Inc. Permission required for reproduction or display. Gardner’s Theory of Multiple Intelligences Linguistic Understanding & using language. Musical Skill in the creation of music. Logicalmathematical Spatial Logical thinking & reasoning about quantities. Understanding how patterns & objects are laid out in space. Skill in anything involving complex body movement Bodilykinesthetic Intrapersonal Interpersonal Understanding one’s own feelings & motives. Understanding feelings & behaviors of others.

Sternberg’s Triarchic Theory Whereas Gardner focused on types of intelligence, Sternberg analyzed factors that contribute to making a behavior intelligent or not. Componential element Information-processing skills using in solving problems. Experiential element Prior knowledge that affects how a person approaches a problem. Contextual element The set of circumstances in which a choice is made or an action is taken. Copyright © 2004 The McGraw-Hill Companies, Inc. Permission required for reproduction or display. Explaining IQ Differences There is evidence for both genetic and environmental influences on IQ. The hereditary influence involves many genes. Reaction range refers to the range of possible outcomes from a set of genes, depending on the environment. Some evidence for genetic influences comes from adoption studies. IQ reaction range seems to be about 2025 points. Copyright © 2004 The McGraw-Hill Companies, Inc. Permission required for reproduction or display. The Stability of IQ Stability of IQ increases with age, probably reflecting relatively stable influences of both genes and environment. By elementary school years, intelligence tests seem to measure relatively stable aspects of cognitive functioning. As children grow older, IQ tests become increasingly good predictors of adult IQ. Copyright © 2004 The McGraw-Hill Companies, Inc. Permission required for reproduction or display. How Meaningful Are IQ Scores? Ever since IQ scores were introduced, people have debated their value. The controversy centers on issues of cultural bias and the question of just what an IQ score can predict. Copyright © 2004 The McGraw-Hill Companies, Inc. Permission required for reproduction or display. The Issue of Cultural Bias Cultural bias can affect IQ tests many ways: language fluency knowledge of cultural references cultural differences in definitions of intelligence setting in which test is given Copyright © 2004 The McGraw-Hill Companies, Inc.

Attempts to develop these have not generally succeeded. IQ tests offer effective comparisons within the same culture or subculture. Copyright © 2004 The McGraw-Hill Companies, Inc. Permission required for reproduction or display. What IQ Scores Can Predict In general, IQ tests are fairly good predictors of success in school. Childhood IQ may predict long-term success in occupations that require abstract thought. Adult IQ scores are good predictors of success in job-training programs but not of actual job performance.

The transition to formal education is not always easy. Many have difficulty applying their informal knowledge to more formal classroom tasks. Decontextualized thought: A cognitive skill needed to solve problems that are abstract, self-contained, and removed from any immediate context. Copyright © 2004 The McGraw-Hill Companies, Inc. Permission required for reproduction or display. Cultural Mismatch The format of social interaction expected at school may be unfamiliar to children from different backgrounds. White middle-class preschoolers are accustomed to being asked questions at home, test questions to which the adult knows the answers (“What color is that?” “What do cows say?”). A study found that black lower-class preschoolers heard more functional questions at home: analogy questions (“What’s that like?”) story-starter questions (“What happened to him yesterday?”) accusation questions (“What’s that all over your face?)

Cultural Differences in Math Achievement United States children do worse than children in many other countries on math & science measures. No one suggests American children have learning deficiencies compared to children in other countries. Researchers and teachers assume cultural differences in values & classroom practices must be the cause. Copyright © 2004 The McGraw-Hill Companies, Inc.
