Methods in my own Research
Preliminary validation of the survey instrument, data collection, data analysis and further validation of the instrument
progress in a cyclic fashion. Student responses to open ended questions are used both as qualitative data in their own right,
and to refine the questions for future use. See also my website on conducting rigorous educational research.
Ocean Literacy Data Collection
We collected quite a bit of data:
- Fall, 2005, 10 honors students completed and commented upon two preliminary surveys
- Janary, 2006, my 120 students completed open format survey
pre-test in class
- January, 2006, 20 students in E. Knowles distance-learning class completed
pre-test online
- February, 2006, 20 high school students competing in North Carolina Ocean Sciences Bowl completed
post-test
- April, 2006, My 120 students completed several surveys
- April, 2006, E. Knowles' 20 students completed open format survey as post-test
- August, 2006, 12 honors students completed 3 surveys
- December, 2006, 12 honors students completed revised survey
- post-test: Content, science attitudes, conservation attitudes
- January, 2007, 16 students in my First Year Inquiry Course pre-test
- January, 2007, 13 students in Ernie's course, pre-test

Data Analysis
Qualitative Data
- thematic content analysis
- what gets students interest
Validation and Reliability
- types of validity & reliability
- qualitative Vs quantitative data
- cognitive Vs affective domain
- iterative process
Validation and Reliability
Content Validation: Work with Experts
- Essential Principles and Fundamental Concepts from COSEE, 2005
- focusing on EP1 (size of ocean), EP4 (habitability), EP5 (biology) and EP6 (human connections)
Construct Validation: Work with Students
- choices from open ended questions: ocean depth, where learned
- whole class discussion of wording coriolis question
Criterion Related Validation
- Survey use in different settings => different types of responses
- correlate literacy scores with my grades & Ernie's
Reliability
- inter-rater reliability for ecosystem question
-
