For improving the survey: I don't have the sources (a few hundred papers / articles) anymore, rather this was for my own research in designing surveys for companies garnering feedback from IT Director (mostly) levels. For buy-in, Saliency of Questions and Subject Matter is key to engagement (finishing the survey). Assume that respondents will fade towards the end of the survey. Your most important bits of information that you want to get from respondents should be towards the beginning after a few "warm up" questions, so you get the data you want without the drop-off. Assume each question that is not open ended is ~ 1 minute:1 question. This will help you determine length. Most engagement drops off ~10-15 minutes. These questions INCLUDE Name, email, etc. (also, you may want to drop the name req., as other commenters are pointing out). Surveys of 20 minutes can be very "long" and have a much higher chance of not finishing the survey without interest-engagement (video, graphics, saliency of questions). Research showed that length doesn't necessarily drop engagement, but poor questions (relevance / saliency) does. You will want to tighten up the questions, reduce the # of open-ended questions (how are you going to compare all of those?) You could instead make radio-text boxes (seeing you are using Google Forms), such as: What did you first make the computer do: Option 1,2,3,4,5, Other (as a text line). What language could also be radio-boxes (to shorten respondents time to type). You are also requiring random open-ended questions to be completed (red asterix), or the form will not submit. You will lose much engagement this way. Also note why you are gathering this (I assume for schooling), which would perchance help with privacy concerns (though you don't need anyones real name).
