American Military University
American Public University
• Founded in 1991 as American Military University (AMU) by James P. Etter, retired Marine Corps Naval Flight Officer and instructor at the U.S. Marine Corps’ Amphibious Warfare School
• Focused curriculum on mobile military learners• Expanded into APU/AMU in 2002• HLC accredited, with +190 associate, bachelor’s, and master’s online
degrees and certificates

• Military students, spouses and dependents, especially those deployed, pose unique challenges
• Cannot participate in traditional, synchronous, F2F classroom events and schedules1,2
√ responsibilities √ schedules √ geography √ technology√ accessibility √ logistics
• Increasingly reliant on online education3
• This requires a subset of online teaching best practices4,5

• The lab experience likely plays the central role in science education6,7,8,9,10,11,12
• How can deployed military students feasibly receive a rigorous and authentic experience?
• How can they use physical manipulatives and equipment to generate their own data, analyze it, draw conclusions, and reflect critically on their work?
So What About Labs?
![Page 6: The Mobile Lab: Teaching Hands-On Science to Military Students](https://reader031.vdocument.in/reader031/viewer/2022012407/616a282f11a7b741a34f6b95/html5/thumbnails/6.jpg)

• Support for military student learning (and retention) should include multiple learning modalities3
• Online classroom not typically “hands-on”• “Hands-on” is a hallmark of science education!
What Does Researchand Best Practice Suggest?
![Page 7: The Mobile Lab: Teaching Hands-On Science to Military Students](https://reader031.vdocument.in/reader031/viewer/2022012407/616a282f11a7b741a34f6b95/html5/thumbnails/7.jpg)

• Should labs be part of all science classes?• What is the purpose of laboratory experiments in
undergraduate science education? What are the broader learning objectives?
• Do our assessments actually assess the purpose and objectives?
• Can these objectives and assessments be delivered at a distance (i.e. via an online course)? If so, how?
Let’s Take a Step Back

• Current research suggests it is possible to meet laboratory learning objectives using virtual or remote laboratory methods13
• Blending virtual labs with a traditional hands-on option caters more to the multi-modal needs of military learners
Why a Kit for Military Students?
