Exam 1 Flashcards
- What are the five different types of research designs
Descriptive Correlational Experimental Single subject design Quasi-experimental
Descriptive
Describes variables but does not make connections between variables, events, or conditions.
Socioeconomic status
- Socioeconomic status, relies on the educational level and occupation of family members rather than on their level income
Stereotype threat
- A situational predicament where people at risk of confirming negative stereotypes about their social group.
- They matter because they can affect the person’s behavior, their level of performance, etc.
Formative and Summative
Formative
- Enable teachers to plan for instruction and monitor student progress throughout a grading period. (homework, quizzes, exit sheet)
Summative
- Assess student achievement at the end of an instructional unit or grading period. (test, exam, cumulative projects)
- Name the four categories of standardized tests
Standardized achievement tests
Standardized aptitude tests
Career or educational interest inventories
Personality test
Standardized achievement tests
- Assess current knowledge, which can included learning outcomes and skills either in general or in a specific domain. Identify the strengths and weaknesses of individual students as well as school districts.
Standardized aptitude tests
- Assess future potential, used for admission or selection purposes to place a student in particular school, specific classrooms.
- What is a standard deviation (SD)? What does a large SD mean? What does a small SD mean?
Standard deviation
- The degree of variability in a group of scores
Large SD
- Suggests that the scores are more spread out
Small SD
- Indicates that most cores are close to the mean score of the group
- What is a frequency distribution? Describe skewness
- Is the simple list of all scores for a group
Skewness - Symmetry or asymmetry of a frequency distribution
- Negative skewness indicate that scores are piled up at the high end (liens right)
- Positive skewness indicates that scores are piled up on the low end. (liens left)
Measurement error & types
Measurement error
- Is the accumulation of imperfections that found in all measurements
Types of measurement errors
- Item selection – clarity in wording of question
- Test administration – harsh tone increase students anxiety
- Individual factors – illness, fatigue
- Test scoring – subjective, such as essay
Reliability VS validity
Reliability
- The test score or measurement, is measured on a continuum from high to low
Validity
- The extent to which an assessment actually measures what it is intended to measure
Types of validity
- Content – evidence provides information about the extent to which the test items accurately represent all possible items for assessing the variable of interest.
- Criterion related - evidence shows that the test score is related to some criterion, an outcome thought to measure the variable of interest.
o Concurrent
o predictive - Convergent – evidence shows whether the test score is related to another measure of the construct.
- Discrimination – evidence demonstrates that a test score is not related to another test score that assesses a different construct.
- Theory based – evidence provides information that the test scores are consistent with a theoretical aspect of the construct.
Hierarchical theories
(cattell and horn) – two separate general factors.
- Gc – general crystallized intelligence, individuals pool of knowledge and facts
- Gf – general fluid intelligence, individuals potential for learning
Multiple intelligences
Gardners
- Intelligences are independent of one another but interact and work together Intelligences are abstract but exist in a person’s interaction with objects and people in the world
- Linguistic – words to communicate ideas
- Logical/mathematical – reasoning, recognizing patterns
- Musical – recognizing musical components
- Kinesthetic – ability to use one’s body
- Spatial accurate perception of visual-spatial world
- Interpersonal – identification/responding to emotions of others
- Intrapersonal –knowing strengths/limitations
- Naturalistic - recognizing/classifying the natural world
