I have been a fan of Google Forms for quite a few years. Google has made some recent changes as to how the screens appear and where. This video is particularly good from the standpoint of its simple explanations. What you are seeing are screens following the recent changes.
Those who have attended my workshops will notice a slightly different approach. I create my spreadsheet first, listing my questions across the top of each column which then populate the form. This video shows creating the form first and then viewing the spreadsheet. Either approach works. I prefer to “begin with the end in mind,” and therefore start by constructing the spreadsheet into which my data will feed.
