Ch. 7 - Body and Mind Flashcards
Reaction time
The time it takes to respond to a stimulus, either physically or cognitively
Childhood Overweight
In a child, having a BMI above the 85th percentile, according to the U.S. Centers for Disease Control’s 1980 standards for children of a given age.
Childhood Obesity
In a child, having a BMI above the 95th percentile, according to the U.S. Centers for Disease Control’s 1980 standards for children of a given age.
Asthma
A chronic disease of the respiratory system in which inflammation narrows the airways from the nose and mouth to the lungs, causing difficulty in breathing. Signs and symptoms include wheezing, shortness of breath, chest tightness, and coughing.
Concrete Operational thought
Piaget’s term for the ability to reason logically about direct experiences and perceptions.
Classification
The logical principle that things can be organized into groups (or categories or classes) according to some characteristic that they have in common.
Seriation
The concept that things can be arranged in a logical series, such as the number sequence or the alphabet.
Knowledge base
A body of knowledge in a particular area that makes it easier to master new information in that area.
Control Processes
Mechanisms (including selective attention, metacognition, and emotional regulation) that combine memory, processing speed, and knowledge to regulate the analysis and flow of information within the information-processing system. (Also called executive processes.)
English Language Learners (ELLs)
Children in the United States whose proficiency in English is low—usually below a cutoff score on an oral or written test. Many children who speak a non-English language at home are also capable in English; they are not ELLs.
Immersion
A strategy in which instruction in all school subjects occurs in the second (usually the majority) language that a child is learning.
Bilingual Education
A strategy in which school subjects are taught in both the learner’s original language and the second (majority) language.
ESL (English as Second Language)
A U.S. approach to teaching English that gathers all of the non-English speakers together and provides intense instruction in English. Students’ first languages are never used; the goal is to prepare them for regular classes in English.
Hidden Curriculum
The unofficial, unstated, or implicit patterns within a school that influence what children learn. For instance, teacher background, organization of the play space, and tracking are all part of the hidden curriculum—not formally prescribed, but instructive to the children.
Trends in Math and Science Study (TIMSS)
An international assessment of the math and science skills of fourth- and eighth-graders. Although the TIMSS is very useful, different countries’ scores are not always comparable because sample selection, test administration, and content validity are hard to keep uniform.
