Goddard and Hoy Six Term Scales
Partially in response to Irina's post, I also wanted to comment on response scaling. While perhaps very effective, I think 100 point scale system is cumbersome to work with. Likewise, a 1 to 5, is perhaps too simplistic. If you have not seen the teacher efficacy CE-scale created by Goddard & Hoy (2003), please have a look at it. Obviously adapted from a Likert type scale, using this six term scale, teachers were able to record levels of agreement ranging from strongly agree, agree, somewhat agree, somewhat disagree, disagree and strongly disagree. I don't know what it is about this particular measure, but it is visually very appealing and not to complex for respondents to record strength of beliefs or in turn to score. Please look it up and let me know what you think?

Mark,
ReplyDeleteIt's interesting that you mentioned this 1 to 6 scale. I don't know if it's better than 1 to 7 statistically, but it does seem easier psychologically because it is smaller than 1 to 7. The only difference I see between them is the mid-point, which is present in 1-7 but is absent in 1-6. I'm not sure if we need it or not.
If we follow 1-6 scale, then it can be phrased as follows:
Rate the following statements using numbers from 1 to 6, where
1 = not confident at all,
2 = not confident,
3 = somewhat not confident,
4 = somewhat confident,
5 = confident,
6 = highly confident.
When I think of that, I don't see the meaningful middle for our phrasing, so I like your idea!
I am interested in this! I wonder if it's better to allow participants to choose a neutral option or if it's better to force participants to decide if they're more/less confident.
ReplyDeleteI think this issues simply comes down to what Anna mentioned: Do we want to give the "neutral" option to those completing the scale? I think there are legitimate arguments for both....the more I think about it, the more I am attracted to the 1-6 scale. Now I'm doubting myself. Thanks Mark! No, seriously.
