Challenges:
 Getting students engaged
 Getting students prepared
 Increasing confidence in the lab
 Students ran out of time

 Students didn’t do
the work
 First 15 minutes used
to catch up
 Labs became recipe
following exercise

Demonstration
Interactive practice
Quizzes

Demonstration activities HTML5
 Provide key information and concepts
 Videos and stepped calculations
 Gives students control

Practice activities HTML5
 Highly interactive
 Involve decision making and problem solving
 Hands on
 Setting up equipment, performing techniques
and working through calculations

Quizzes
 Test information from demonstration and
practice activities
 Pre-populated
 Create custom quizzes
