Qualitative VS. Quantitative

I used both quantitative and qualitative data in my research. For my quantitative data I used a pretest and posttest. I used the scores from the previous week's comprehension test (without the treatment) and compared them to the comprehension test to a new story (with the treatment). This helped me determine if VoiceThread was useful in helping students comprehension level increase. Even though there was a small increase it was not significant enough to show that it helped their comprehension level. For Qualitative data I used a Self-Assessment survey and observation notes. I chose to do a self assessment survey based on time it was easier than interviewing 23 students. The self assessment survey was also better than written responses based on my grade level. Students were able to circle the smiley face based on how they felt about the question. There were five questions on the survey about VoiceThread and working as a group. The questions were: 
1. How did you feel about using the digital tool to retell the story?
2. How did you feel about working in a group?
3. How do you feel this helped you remember the story?
4. How do you fell you and your group did on retelling the story?
5. How would you feel about doing this again?
Students were also given a choice to write a sentence or two about why they answered the way they did. Only eight students responded with a sentence (one was not legible). This helped me determine if students enjoyed the using the tool and working in groups, and how it affects their intrinsic motivation. Question number 5 showed that almost half of the students did not enjoy using the digital tool. I also took observations and noticed that one group did not like working together and this showed their disinterest in the project.
