Active Learning ≡ Interactive Engagement
……….heads-on (always) and hands-on (usually) activitieswhich yield immediate feedback through discussion with
peers and/or instructors...
Socio-cultural perspective

Talk in Lectures - 3 Perspectives:
1. Quantitative analysis of talk: (Framework for Interactive Learning in Lectures).
2. Lecturer-Student interactions.
3. Peer-discussions.

Part 2: Lecturer-Student interactions
Part 2: Lecturer-StudentInteractions
Research Questions
1) What are the purposes of lecturer-student dialogue?
2) What is the nature of the dialogue? (e.g. dialogic vs authoritative)

Example 1
Lecturer:
Ok, so what did you say, so here’s what we said (shows graph), that’s an 80% win for option B and roughly equal for A and C as well there. So option B, 7 Joules , 7 Joules work done during that expansion.

● Dialogic or Authoritative?
Dialogic Interaction:
More than one voice is heard and there is an exploration or ‘interanimation’ (Bahktin 1935) of ideas.

Example 1 (continued)
Lecturer: Why is it 7 Joules, how did you
calculate that?
Student: area under the graph …..
Lecturer: yep,

● Example 2
Lecturer:
Why might someone say option C? What led you to think there is no heat transferred in this situation?

● Example 2
Lecturer:Why might someone say option C? What led you to think there is no heat transferred in this situation?
Lecturer:
Anyone disagree with that, anyone agree with it? ….What do you think?

● Dialogic or Authoritative?
‘Ideologically Dialogic’
Equal social relationships, intellectual openness and opportunities for creative thought. But can be discursively monologic.

1. Feedback
2. Involving Students in Sense Making (Peer-Instruction)
3. Guided Expert Thinking/Problem Solving

● Lecturer-Student Conclusions4 purposes of dialogue in large lectures
classes identified
Dialogue can be technology mediated
Interactions predominantly ‘authoritative’ …..
….but overall these are ‘ideologically dialogic’

Part 3: Peer-Discussions
Peer-Discussion Conclusions
● Peer discussions help students to:• Activate knowledge connections• Make links to other ideas• Try different approaches to problem solving
● Student-student discussions are more than just ‘one student teaches another’
![Page 43: It's good to talk especially in lectures!final2](https://reader035.vdocuments.net/reader035/viewer/2022070516/5875040e1a28ab29208b5f09/html5/thumbnails/43.jpg)
Course Design
Part 3: Peer-Discussions
Final ThoughtsStudying the way talk is used in active learning lectures:
Highlights the importance of lecturer talk used in combination with student-centred activities
Shows the variation in lecturer-student interactions (and the challenges of generating productive talk)
Gives insights into the thinking processes during peer-discussion
