  • University, Community College, and High School
  • What is the benefit of technology in the classroom?
  • Now we want to talk a bit about classroom response system. Here is how they work.
  • And these are the types of exercises that are enabled by these systems, start with simple multiple-choice questions, and more to more complex digital ink questions
  • Need to make it clear why you are showing this slide
  • Pedagogy relies on aggregated results and discussion with neighbor Used for attendance and keeping people awake (these are wrong reasons).
  • Showed that their technology was preferred to raising hands or cards in class
  • Whole Slide and Post-It can be used for ? Asking, Short Answer, Numeric, and Multiple-choice. This just shows the primary types of exercises that they are used for.
  • Whole Slide and Post-It can be used for ? Asking, Short Answer, Numeric, and Multiple-choice. This just shows the primary types of exercises that they are used for.
  • Brecht  41 Activity Patterns (Question Posing, Multiple Representations, Simultaneous Annotation, Image Mapping) DiGiano  Moon Phases Pattern (partial knowledge), mostly deals with communication in small groups I am interested in patterns of activities styles based on the information that instructor wants to gain from the activity.
  • Transitions to next slide: Let’s look at some of the dimensions that we need to consider for our device First input, Also, screen size
  • Multi-device data to test on
