Poll Title: A 0.5 kg rock travelling 20 m/s hits the windshield of a parked car, bringing it to a stop in 0.1 s. What is the average force acting on the rock to bring it to rest?https://www.polleverywhere.com/multiple_choice_polls/eQUwzUMDs12qoqH2
Force = mass x acceleration
Remember that: Acceleration (or deceleration) = change in velocity/change in time = (vfinal vinitial)/(tfinal tinitial)Force exerted on the rock = mass of the rock x acceleration (deceleration)A 0.5 kg rock travelling 20 m/s hits the windshield of a parked car, bringing it to a stop in 0.1 s. What is the average force acting on the rock to bring it to rest?

Take Away Concepts Whats it like to use an CRS? What is a CRS? Challenges in Teaching in a Traditional Classroom Benefits of Active Learning through Polling Clickers vs Mobile Devices, or Both Example CRS Systems Questions & References
Whats a CRS? A wireless system enabling students to answer instructor-posed questions. A system that compiles student input in graphical form (pie chart, histogram, word cloud, etc.) A system that can track student input individually behind the scenes (and add to a grade sheet in Canvas)
A set up that uses software and hardware to question (poll) a large group of participants, and display the results onscreen.
A set up where students are given handheld transmitters with which they can answer instructor-posed questions being shown on the screen by the instructor.
Student responses are received wirelessly by the instructor computer and specialized software, which compiles results into a histogram or pie chart, tracking individual responses behind the scenes.
Challenges in the Traditional Classroom Student-instructor interaction limited Students may be reluctant to respond The same students tend to answer all the questions
Instructors cant get a good read on the class Students are isolated within the audience
Having enough time
Student-instructor interaction limited with large class sizesStudents may be reluctant to respond to instructor questionsThe same students tend to answer all the questions, anywayInstructors cant get a good read on class understandingStudents are isolated within the crowd Peer discussion enhances understanding, leading to higher-order learning
Teaching by telling is replaced with teaching by questioning and peer discussion.
Graphs of aggregated responses can include time for students to compare viewpoints and possible revise their answers following apeer discussion.Classroom participation and duscissuion lead to higher-ordre learning.Clickers allow instructor to get a much broader sense of understanding.; clickers enable many more to participate. Can almost guarantee participation.Students reported they were twice as likely to answer a question if responses were submitted by clickers. Testing students often with low-stakes improves their performance ion later high-stakes exams.
Why Implement Active Learning Using Polling? Instructor gets broad class data Allows instructor to change the presentation More participation Immediate feedback Benefit from seeing other votes Good for flipped classroom model Peer discussion enhances understanding Constructivist vs exposition-centered learning Extra benefit for disadvantaged or female students
Constructivist: Ask, Dont Tell
Exposition Learning: Teaching is Telling9
Poll Title: In a review of 225 studies, comparing traditional lecturing with active learning across a broad range of STEM disciplines, the investigators found that:https://www.polleverywhere.com/multiple_choice_polls/TVBxwSAC8BSZ3q710
We have 4 sets of 45 clickers that can be checked out for 2 days or 1 week
UW Bothell Learning Technologies webpageClassroom Response Systems (informally known as "clickers") allow instructors to quickly conduct polling and question-and-answer sessions using PowerPoint or other Office applications. Students submit their responses through small hand-held devices, and the results are displayed immediately. Questions can be developed to guide students through class problems, check their understanding, and collect opinions. Through this type of interaction, instructors can increase participation and more effectively engage their class in discussions, activities, and lectures. Click one of the buttons above to get started. We use TurningPoint 5. We currently circulate four sets of clickers systems: 3 sets may be checked out for 2 days and 1 set may be checked out for a week. Each set includes 45 clickers and 1 receiver that are configured to work with each other.When setting up the system in a classroom, the receiver should be plugged into a USB port on the computer tower instead of the monitor in order to work properly.
Why Use Mobile Devices and Laptops? Cost: Clicker prices are still $30-$40, plus subscription Distribution/collection challenges Clicker receivers have to be set up in lecture rooms Limited clicker sets limit widespread use
However, Many students already own a phone, tablet or laptop Can use university wi-fi/internet or their own data plan Some polling software allows use of both clickers and mobile Issue: The digital divide; polls that rely on texting; reliability
Cell phone data connections seem to be less reliable than the univ. internet connection, so most used univ wi0fi. Clickers much more reliable since local radio frequency. Worry that may need to purchase a polling subscription as with Turning Point. Stowell, Jeremy. Use of clickers vs. mobile devices for classroom polling, Computers and Educaiton 82 (2015) 329-334.Some students found using mobile more distracting than clickers as they also contended with text messages, email, notifications, etc.
