What do you do as a TA that helps students learn?
1. Write down your ideas (one per piece of paper)
2. Crumple up the paper and throw it up here
The research question:
Which of these actually matter?

Skills test
Observe all lab sections in the same week.
Setting: Physics 100 lab
• Large class: ~700 students in 16 lab sections
• Weekly 1.5 hour lab with 2 TAs
• Average of 39 students per lab section
Lab progression Intro and clicker questions
Extended period of students working in pairs (Observations during this period) Outro and clicker questions
Participants: The TAs of Phys 100
• 6 first-year grad students with no prior teaching experience
TA observations
• How do TAs adhere to and deliver the lesson plan? 1. Note TA behaviours outside of the standard script
• Examples: Using the chalkboard to discuss a point, playing music from YouTube, having a back-and-forth with TA partner during a class discussion
• How do TAs interact with students during the work session? 2. Number of TA-student interactions 3. Who initiates the interactions? 4. Length of interactions
TA observation form allows one to record a timeline of TA’s behaviour during the lab

Which TA behaviours contribute to student engagement and learning?
r = 0.56*
r = 0.52
r = 0.28*
(Frequency of interactions used for TA behaviours)
Discussion
• Frequency of interactions is correlated with engagement – Whether it’s a carrot or a stick
• Our opinion: frequent interactions (even just saying ‘hi’) allow and encourage student access to the TA – Be present in the room
(Student)
Discussion: 3 possible TA styles
As a lecture TA, I could: 1. Wait until a student puts up their hand. 2. Approach a single student, ask how they
are doing. 3. Ask an entire section of students how
they are doing.
Conclusions
1.
2. What TAs do in class matters.
