Glossary of The Historical Perspective of Distance Education
Created by hbeezley
- Summative assessment
- occur at the end of instruction. examples: unit tests, projects
Goal - establish how well the learner has achieved the knowledge and skills associated with that unit - certify achievement, assign grades
- Formative assessment
- occurs throughout and during the unit of instruction.
Goal to help ensure high achievement at the end of instruction.
Can be informal
- degree to which a test measures what it is supposed to measure
- Sampling error
- occurs when there is a difference between responses provided by the sample and responses that would have been obtained had the entire population participated
- an approach used to evaluate sampling error.
- The four generations of distance education
- 1. single technology
2. multiple technologies (no computer)
3. multiple technologies with computer (no high bandwidth network)
4. multiple technologies with computer and high bandwidth
- Assessment issues introduced with single technology distance education
- Does learning achieved at a distance equal learning achieved face-to-face?
With learners at a distance, how does one achieve formative assessment?
With learners at a distance, how does one go beyond measuring declarative knowledge?
- Assessment issues introduced with multiple technologies distance education (without a computer)
- How can one validate the assessments? Construct and content-related approaches are the primary means of validation
- Assessment issues introduced with multiple technologies distance education (with a computer and no high speed network)
- With randomized questions, how can one ensure each student\'s tests is equally difficult when different sample of items are used with each administration?
Would decisions about a student\'s level of mastery be the same if a different sample of items were included in the test?
- Assessment issue introduced with multiple technologies distance education (with a computer and with high speed networks)
- How does one assess higher-level skills? Is the use of advanced media synonymous with assessing higher-level skills?
