“Easy to Use”

Funny how every app claims that. But how do you really know? Answer:

A stopwatch.

A great app helps you work more efficiently, while a clunky one takes a few extra seconds each step. What’s the big deal? Teachers do thousands of clicks per day, so thousands of extra seconds makes your work week an extra hour longer!

This video shows screen captures of each LMS and how much time it takes teachers to do common tasks.

Task 1:  Grading Assignments

25 students turned in writing assignments. Insert 4 comments and enter a grade for each student.

Rank Time* Speed
#1   Jupiter 275
#2   Canvas 400
#3   Schoology 550
#4   Google Classroom 579

Task 2:  Create Quiz

Create a new quiz with 10 questions.

Rank Time* Speed
#1   Jupiter 16
#2   Canvas 23
#3   Schoology 32
#4   Google Classroom 48

Every Second Counts

Teachers do thousands of clicks per day, so every extra second adds up:

Fast App 1000 clicks/day
Slow App 2000 clicks/day


1000 extra clicks/day

5 Days 5000 extra clicks/week

Work Week

1.4 hours extra work


Here’s the fine print on how speed was measured:

We counted each step as 1-2 seconds:
1 second per click or double-click (2 clicks for menus)
1 second to type a number
2 seconds to type brief text
Time was not counted to read assignments or type test questions, since that depends entirely on you, not the app.
Speed graph = 1 / time
Only required steps were counted, not optional steps.
Any available shortcuts were used.
Although some apps had noticeable server lag times, that was not counted.
Trials were conducted on a laptop computer in Sept. 2020.
Task 1 required inserting 3 common corrections and 1 unique comment.
Task 2 required 6 multiple-choice questions then 4 short answer questions, all 1 point each.
