First, I start with my question:

slide12

Follow-on Questions:

* What about NC breweries?

* What about ENC breweries?

Females?

Took ACA?

Males?

Minorities?

Non-Traditional?

Fall-to-Fall?

Nursing?

Cosmetology?

Fall-to-Spring?

Used AS?

Applied?

Transfer?

GOT?

slide15

A little closer to home…

What’s up with DL at CCC?

Do DL students drop as much as traditional/seated students?

Related but separate question: Do DL students succeed as much as traditional/seated students?

If NO, then what’s going on?

dl @ ccc fa 08

now what about triangulation
Now, what about Triangulation?

Now, what about Triangulation?

Nothing wrong with Qualitative Data-

Surveys, Evaluations, Focus Groups

What do you think about online courses?

Where have you succeeded with online?

Where have you struggled online courses?

Where have you succeeded with this course?

Do you prefer Hybrid or Full Internet?

slide26

Rate these assignments from easiest (1) to most difficult (5).

    • _ Word
    • _ Excel
    • _ Powerpoint
    • _ Access
    • _ Integration
    • _ Theory
slide27

In Sum…

  • Think about your question(s)…Outcomes?
  • Where’s the data?
  • How can you aggregate it for meaning?
  • How can you dis-aggregate it for usefulness?
  • How can you triangulate it for validity?

The Important Stuff

Was this what you expected?

Suggestions for improvement?

Would you attend follow-up sessions (on drilling deeper)…(or something else)?
