Hi everybody........
m looking for some clarification.
I am planning to conduct a study for my dissertation and this is what i have planned. There will be the following kinds of data
1. questionnaires on student motivation (will provide quantitative data)
2 questionnaire on school effectiveness ( -do-)
3. questionnaire on problems in school ( -do-)
4. interview on perceptions of school (qualitative data)
5. classroom observation. (qualitative data)

Now, i plan to convert the qualitative data from interviews and class observations into quantitative data by assigning scores to the categories.
Is this an accepted mixed method research.

Why????

It sounds like a mixed methods case study, though there is no need to do this:

"i plan to convert the qualitative data from interviews and class observations into quantitative data by assigning scores to the categories."

you can synthesis/interpret qualitative and quantiative data together without having to convert it to one type. Mixed methods allows this.
