Why are probes valuable tools?
• displays immediately data that one normally can’t see with another device (sonar ranger displays velocity and acceleration)
• collects data faster than normal devices (sometimes over thousands of times per second)
• records and displays data collected over long periods of time (some even up to a year)
• displays simultaneously on the same graph combines the collection from multiple probes
• uses the results of two or more different probes to provide a derived display (for example, electrical power being displayed from data collected from a voltage and current probe)

Ideal Learning Environment
• Dynamic nature of atomic/molecular systems not easily conveyed with text and static images.
• Animations help, but don’t allow students to construct knowledge. Student is passive learner.
• Models which are computed in real-time allow users to probe the simulation by changing parameters. Student becomes an active learner.

Other reasons to like models
• Help to provide a concrete scaffold for new abstract concepts.
• Can be used in guided inquiry mode.
• Promotes reasoning and supporting ideas with evidence.
• Can link to macro-scale phenomena.

A Couple of Quotes“A concise summary of the last 100 years of science is that atoms and molecules are 85% of physics, 100% of chemistry and 90% of modern molecular biology.”
- Leon Lederman
“... all things are made of atoms — little particles that move around in perpetual motion, attracting each other when they are a little distance apart, but repelling upon being squeezed into one another.”
- Richard Feynman

• Going deeper can simplify science• Most scientific phenomena can be explained by fundamental ideas of the atomic nature of matter, conservation of energy, Nature’s tendency toward equilibrium.
• Science through this lens is more connected - less individual facts to “memorize”.
• Conceptual understanding is the goal.
• Utilize interactive models, to allow inquiry at the atomic level.
• Teachers are essential for inquiry approach to work.
Inquiry Is Key

Research Findings
• Modeling software that is sufficiently flexible and thoughtfully applied results in deep learning.
• Interactivity creates the rich, highly associated mental network of concepts that we know contributes to lasting understanding.

Research Findings
• Interactive models are visually engaging in a way that makes them accessible to students with different learning styles.
• Student explorations can lead to an understanding of connections between atomic-scale events and those events that they can observe at the macroscopic scale.

Technology is Not a Magic Bullet
• Tech is just a tool
• Can be used poorly or to better engage students
• At the student level - primary use is to improve inquiry
• For teachers - more efficient management and communications
