Introduction to computers QR code scavenger hunt
This task could be used to find out what students know, or to help students revise and understand key hardware terms. Students will need mobile phones with a QR reader app. Some students will need to work in pairs if they are without phones. You could set homework the previous week to download and use a QR reader onto their phones. 1) Print off the QR codes, cut them up and display them around the room. Click here for the codes. 2) Hand out the following questions to students or display them on the whiteboard: A1. Any piece of computing equipment you can touch. 2) Get students into pairs. They should jot down what they think the question is to each answer. Use a 5 minute countdown clock for this task. 3) Go through some random answers and get ideas for what some of the questions might be. 4) Explain to students that there are 20 questions around the room in the form of QR codes. Their job is to find and write down the question that goes with the answer. Explain that there are also 5 questions without answers. They also have to come up with suitable answers for those 5 questions, perhaps using books and the Internet. 5) Students who finish could find out how to make up their own questions and answers to test other students with in the form of QR codes and then make a few. 6) Bring the class together and go over the answers for the 5 questions where no answers were supplied.
