Mission Statement EnGauge gives students a platform to anonymously and immediately give feedback to professors, and allows professors to address this feedback during the lecture.

Tasks Task 1: Gauging speed of class Task 2: Asking good questions Task 3: See which topics confused students

Choosing Interfaces

Student Interfaces

Selected Interface: Student Interface Less cluttered with words. Different size of questions makes it clear which ones are popular. Separate submit screen: big font, less distracting.

Professor Interfaces

Selected Interface: Professor Interface Bar rather than dial: can fit as toolbar at top of screen. Changes color rather than showing meter: easier to glance at, less distracting. Results shown in line graph rather than separate pie charts: easier to compare topics to each other.

Who?

Who? Stanford students: 2 section leaders 1 regular student

Who? First section leader performed as student, then teacher Next section leader paired with the student

Method (Fake class) Task 1: Gauging speed of class Task 2: Asking good questions Task 3: Viewing report

Method (Fake class) Task 1: Gauging speed of class Student: Use gauge to speed up and slow down Task 2: Asking good questions Student: Ask and upvote questions Task 3: Viewing report

Method (Fake class) Task 1: Gauging speed of class Student: Use gauge to speed up and slow down Professor: Change pace of lecture given feedback Task 2: Asking good questions Student: Ask and upvote questions Professor: Answer top questions Task 3: Viewing report Professor: View post-class report

Method: Looking for

Method: Looking for How long it took for user to interact with the app for the first time.

Method: Looking for How long it took for user to interact with the app for the first time. How frequently they looked at or were distracted by the app.

Method: Looking for How long it took for user to interact with the app for the first time. How frequently they looked at or were distracted by the app. How ‘students’ submitted questions and ‘teachers’ answered them.

Overall Results

Overall Results All users interacted with the app within 30 seconds of the ‘class’ starting, spent first couple minutes only interacting with the speed dial.

Overall Results All users interacted with the app within 30 seconds of the ‘class’ starting, spent first couple minutes only interacting with the speed dial. Students distracted by questions, professors not very distracted.

Overall Results All users interacted with the app within 30 seconds of the ‘class’ starting, spent first couple minutes only interacting with the speed dial. Students distracted by questions, professors not very distracted. The option to ask questions encouraged students to come up with questions, professors answered questions immediately.

Task 1: Gauging speed of class

Task 1: Gauging speed of class (Student) Wondered why arrows?

Task 1: Gauging speed of class (Student) Wondered why arrows? Found yellow unnecessary.

Task 1: Gauging speed of class (Student) Wondered why arrows? Found yellow unnecessary. Understood red meant confused, but did not guess it meant slow down.

Task 1: Gauging speed of class (Professor) Thought yellow meant slow down rather than a good pace.

Task 2: Asking good questions

Task 2: Asking good questions (Student) Didn’t understand that Ask button meant Ask your own question until clicking on it.

Task 2: Asking good questions (Student) Didn’t understand that Ask button meant Ask your own question until clicking on it. Understood upvotes

Task 2: Asking good questions (Student) Didn’t understand that Ask button meant Ask your own question until clicking on it. Understood upvotes Did not understand how to get to question page at first

Task 2: Asking good questions (Professor) Answered questions immediately

Task 3: Viewing Report

Task 3: Viewing Report Liked the dots and questions but would not immediately think to press them.

Task 3: Viewing Report Liked the dots and questions but would not immediately think to press them. Understood the graph, most interested in clicking on low or high dots.

Suggested UI Changes

Task 1: Gauging speed of class

Task 1: Gauging speed of class Get rid of yellow

Task 1: Gauging speed of class Icons rather than arrows (Tortoise and Hare?)

Task 2: Asking good questions

Task 2: Asking good questions Clearer distinction between ‘?’ on first page and the red arrow.

Task 2: Asking good questions ‘Ask New Question’ rather than ‘Ask’

Task 3: Viewing Report Icons instead of simply dots
