Refocusing my research questions

Having revisited and then categorised the data from the seven interviews, I've rewritten the my original research questions (submitted within my 17 December Research Proposal). On reflection, questions 2 and 3 from my Research Proposal cover too much of the same ground. Also, the questions ignore the conditions that promote/discourage multimodal approaches to assignments, which has been one of more interesting themes to emerge from both the data and my lit review. I think the new combination of questions are also more able to directly address my overarching question posed within the dissertation. Anyway, I have gone...

From this:

The focus of my research will be upon the experiences and attitudes of tutors towards multimodal assessment. Although it is expected that research questions will emerge and evolve during the literature review, I anticipate considering the following themes:

1. What rationale do tutors apply when choosing to make use of multimodal assessment?
   
2. What are the implications in terms of interpreting the quality of a multimodal assignment? In particular, how are assessment criteria defined in order to judge the quality of a multimodal artifact?
   
3. How does a shift towards multimodal assessment reframe the role and experience of the marker? 

...to this:

The overarching question I set out to investigate within this dissertation was how the growing the potential for students to present ideas across a range of modes impacts upon tutor approaches to assessment in digital education. To explore this topic I investigated three research questions:

1. What are the reasons or factors that encourage tutors to take a multimodal approach within summative assessment exercises?
2. What are the conditions that promote or discourage students from taking a multimodal approach in the response to summative assessment tasks?
3. How do tutors approach the marking of multimodal artefacts submitted for assessment, in particular, what are the implications for measuring the quality of work in relation to established assessment criteria?
