About

Questionnaire App

Read full description

Questionnaire is an educational tool made for increasing teacher and student in class engagement. One of the advantages of Questionnaire is that the teacher does not need to prepare questions prior to class. Questionnaire allows the teacher to freely engage the students with a question anytime. The students can answer the questions by clicking a response. The students can also engage the rest of the class by asking a question and the teacher can support the question by suggesting ABCD choices or true/false then let the class respond. In this way, Questionnaire opens up the opportunity for students to ask questions and also 'game' their scores.
