A Google Form is the first step in the data collection process. It can be a survey, a quiz, a questionnaire, a reflection, preassessment, a sign up ~ whatever you need it to be.
A form needs to be understood. It has three major parts, the 'creation/edit mode', the live view and the collection/spreadsheet view.
Start by creating a simple survey. Ask name, email and one multiple choice question. Or don't even ask for name and email, make it anonymous. Give an audience the link to take the survey and the results come to a spreadsheet.
I will show you how it works.
