Pretest Paper Prototyping Briefing Form

Background information on the User Interface: Clicker

The Clicker comprises of two components

-  The student response unit (figure on right)

-  The TurningPoint software.

When used in conjunction with ResponseCard® student response unit, creates a

wireless student response and voting system that enables lecturers to develop

and administer real-time assessments of student participants from within

Microsoft PowerPoint.

Current clicker

-  Used for collecting student responses to real-time MCQ quizzes

-  Individualized: tagged to the student’s matriculation numbers.

Purpose of our design

Since this new implementation serves to increase in-class participation in general, our new and

improved design hopes to increase participation i.e. ask questions and answer questions via the

usage of the [] button. Certain features of the original design are also changed in order to help

improve the feedback mechanism i.e. inclusion of a small screen, change in light colour and

frequency.

Some features of the software will be changed to help accommodate changes made to the student

response unit i.e. the toolbar on the lecture slides.

New functions

-  Participation: indication of wanting to answer verbally posed questions

-  Assessment: Participation frequency is recorded by software, which can be viewed on

Edventure-  Ask questions: indication that you have enquiries about concepts on slide

o  Current slide

o  Past slide

PRETEST

Greeting and introduction

“Thank you for coming. For our class in Lab in Human Factors, we’re working on Re-designingthe clicker for NTU users that will help In the using it as well as increase class interaction ingeneral. I’ll go over the main points in this form we sent you. The purpose of today’s session isfor you to help us figure out how to make this interface more user-friendly before we finishdeveloping it. But believe it or not, we aren’t going to use a computer. As you’ll see, we’veactually created paper versions of the clicker, and ______ will be playing the computer.”

Their role The two of you will be working together. We’ll give you some tasks that we think arerepresentative of what people might do in real life. Like answering questions using the clicker.Your job is to tell us what makes sense, what’s confusing, whether it works the way you’dexpect it to, etc. Do try to speak what is running through your mind aloud; this will help us

understand how you interact with it.

Social concernsWe’re not going to be videotaping.Keep in mind that we’re testing the interface—we’re not testing you—so if you run into anyproblems it’s not your fault and it means that there’s something we need to change. I’ll be sittingnext to you, and I can help you if you want. We really appreciate having you come and help usout.”

Set expectations“The prototype still has some rough edges—we’re still thinking through how it should work andsome parts of it are incomplete. Before we cast it in concrete, we want to get some feedback

about how well this design works. We’re doing several sessions like this one, so it’s likely thatthe final version of the interface will be different than what you see today. If you havesuggestions we’ll make note of them.“Do you have any questions about what we’ll be doing today?

TESTING

Paper prototype orientation“As I mentioned, here’s the paper prototype of the clicker you’ll be working with. We’ve assumedyou already turned it on and set the channel code. This is your starting point.”Interactions with the prototype and Computer“_____ will be playing the computer. ____may seem like a pretty smart computer, but she has

no speech recognition and no artificial intelligence. Since machines can’t talk, she’s not allowedto explain anything. If you want to do something, you’ll need to interact with the prototype just asyou would do with the clicker. Use your finger to press on the buttons.Please tell us what makes sense to you, what’s confusing, and any questions that come tomind. Your questions are especially valuable, but I may not answer them right away becauseour goal is to change the interface so it answers them.”They are in charge“Remember that we’re testing the interface—we’re not testing you. if you need to stop or take abreak before then, just let me know. Are you ready to start?”Begin first task “here’s the first thing we’d like you to do. Take a minute to read this and let me know if it makessense. If so, then whenever you’re ready please show us what you would do first.”
