The number of club officers reporting strong

The number of club officers reporting at least some knowledge of parliamentary procedure increased from 5 (63%) to 8 (100%).
50% of the 8 participants reported an increase in their knowledge of parliamentary procedure.
Self-reports of knowledge of parliamentary procedure on a scale from 1=minimal to 4=very strong averaged 2.375 before the training and 3.0 after.



Rate your knowledge of parliamentary procedure : 1=minimal 2=some 3=strong 4=very strong

in detail and description.
Data often in a narrative format
Data

often collected by observation, open-ended interviewing, document review
Analysis often emphasizes understanding phenomena as they exist, not following pre-determined hypotheses

Слайд 25 Focus group sample
Q. How are the arts/comm. Activities

Focus group sampleQ. How are the arts/comm. Activities different from other

different from other projects?
When I was little, fair was

never that exciting to me. I didn’t realize how much else there was to do. It’s shown me how many different things you could do and get money for it, so you can’t go wrong.
Art projects are more personal. It’s more of an expression of yourself. Where with an animal, you just show the animal off. With art, you show you can do something good.
(lots of agreement with this).
Q. What about A&C helps with communication?
You’re forced into the situations. A lot of clubs require demonstrations. The first year, everyone encouraged me just to talk.
To have someone push you along the way helps.
In a 4-H Club, you get to be friends. It’s more like family.
If you’re ticked off at your family, you can go up to your room and draw. Feel better.
It feels more comfortable because you’re not the only one. People at school say, “she’s an arts nerd.” You can relate to them. And even they’re so diverse. You cram people in and say you’ve got to get along.
With school, you only go part of the year. With 4-H, it’s all year a few times a month. At school, it’s every single day. It’s too much.
Q. How have you been changed?
Entering art in fair has made me not worry so much about what other people think about my work. I’ll take into consideration what they say, but most of it’s opinion. They can have their own style through photography and I can have mine through sketching.
I think it depends on the suggestion. I usually consider it a lot and it might help me or it might not.
It’s always there in the back of your mind at least.
It’s your own style. If people say, you could change this, I can say thank you for your input, but I’m not worried.
Q. How is 4-H different from other school and community experiences?
Working with people from all over the state and bring their ideas back. Also, how they’re doing the Madison cow parade. I wouldn’t have even heard about that. This year I have one of the micro-cows that was selected.
School is an assignment. You have to do that project. Where 4-H you can do any kind of art, any way you want to do it.
But at school, you can also exhibit. You can get opinions from an art teacher like from a judge. It’s not that different except that you can do what you want.
Although you do learn a lot of techniques from school that you might not learn from 4-H.
