## What is an Interactive Lecture Demonstration?

Interactive Lecture Demonstrations introduce a carefully scripted activity, creating a "time for telling" in a traditional lecture format. Because the activity causes students to confront their prior understanding of a core concept, students are ready to learn in a follow-up lecture. Interactive Lecture Demonstrations use three steps in which students:

**Predict**the outcome of the demonstration. Individually, and then with a partner, students explain to each other which of a set of possible outcomes is most likely to occur.

**Experience**the demonstration. Working in small groups, students conduct an experiment, take a survey, or work with data to determine whether their initial beliefs were confirmed (or not).

**Reflect**on the outcome. Students think about why they held their initial belief and in what ways the demonstration confirmed or contradicted this belief. After comparing these thoughts with other students, students individually prepare a written product on what was learned.

## Why Use Interactive Lecture Demonstrations

Research shows that students acquire significantly greater understanding of course material when traditional lectures are combined with interactive demonstrations. Each step in Interactive Demonstrations--Predict, Experience, Reflect--contributes to student learning. Prediction links new learning to prior understanding. The experience engages the student with compelling evidence. Reflection helps students identify and consolidate that they have learned.

## How to Use Interactive Lecture Demonstrations in Class

Effective interactive lecture demonstrations require that instructors:

- Identify a core concept that students will learn.
- Chose a demonstration that will illustrate the core concept, ideally with an outcome different from student expectations.
- Prepare written materials so that students can easily follow the prediction, experience and reflection steps.
