Term
| features of applied research (2) + eg |
|
Definition
1. solves real world problems
2. increases knowledge of basic phenomena and evaluates theories
eg eyewitness memory research
-IV - po trained in cognitive interview
DV - increased eyewitness info (real world)
-supported importance of context effects on eyewittness memory (basic phenomena) |
|
|
Term
| design problems in applied research (4) |
|
Definition
| 1. ethical issues (consent, debriefing, coercion) 2. decreased internal validity (confounding) 3. between subjects design problems (nonequivalent groups therefore selection/interaction/maturation problems, matching can cause regression) 4. within subjects design problems (no counterbalancing therefore uncontrolled sequence effects, attrition) |
|
|
Term
| examples of quasi-experimental research |
|
Definition
cant determine causation! no complete control over Vs
-single factor non equivalent groups
-nonequivalent groups factorial
-P x E factorial
-correlation
-archival data research |
|
|
Term
| threats in matching nonequivalent groups |
|
Definition
-threat of regression when matched on V in which they differ
-lower group: regression and T work opposingly
-higher group: regression raises scores |
|
|
Term
| def: interrupted time series designs + outcomes |
|
Definition
-program/treatment evaluated by mearsuing performance several times prior to T and several times after T
-general trend (no effect)
-short lived effect
-periodic fluctuation
-ideal outcome |
|
|
Term
| variations in interrupted time series designs (3) |
|
Definition
1. add a control group
2. add switching replication (introduce program in different locations at different times as a built in replication)
3. measure several dependent variables (some expected to be influenced by prog, others not expected to change) |
|
|
Term
advantages of archival research
(2) |
|
Definition
1. virtually unlimited amount of information
2. no P reactivity (hawthorne effect etc) |
|
|
Term
| disadvantages of archival research |
|
Definition
1. some info might be missing
2. experimenter bias (selecting only records that support H1, interpret content of records in biased fashion) |
|
|
Term
| program evaluation features (4) |
|
Definition
1. determine true need and who would benefit
2. whether program is run according to plan/changes to be made
3. evaluating program outcomes
4. cost analyses (weigh prog benefits and $ costs) |
|
|
Term
| needs analysis predictions |
|
Definition
1. population = sufficient size
2. if program would solve a clearly defined problem
3. whether members of pop would actually use the program |
|
|
Term
| needs analysis identification sources |
|
Definition
-census data
-surveys of available resources
-surveys of potential users
-key informants, focus groups, community members |
|
|
Term
| formative evaluation: purpose + procedures |
|
Definition
-monitor progress of program while it is in progress (program improvement)
1. determines if prog is being implemented as planned
2. clear + continuing data on how program is being used
3. pilot study |
|
|
Term
| summative evaluation: purpose |
|
Definition
| -overall assessments of program effectiveness |
|
|
Term
| cost-effectiveness analysis |
|
Definition
| monitoring the actual costs of a program and relating those costs to the effectiveness of the programs outcomes |
|
