||Mini-Labs: Teaching with Inquiry on a Budget
||Students everywhere love chemistry demonstrations -- especially if they involve explosions. But have you ever wanted to move beyond the "wow" factor and find a way to incorporate active student learning into your demos? What if you could get them to think more deeply about what they're observing, and then find out if they really understand what they’ve experienced? Those questions initiated our quest to create “interactive demos” at the US Air Force Academy Department of Chemistry. Over the past year and a half, this effort has evolved into inquiry-based learning activities. We now refer to these activities as “Mini-Labs”, because they also contain the additional dimension of a simple formative assessment of a student’s knowledge and awareness of chemical principles. The “Mini-Lab” was conceived of as an idea to help instructors easily add inquiry-based learning activities to their curriculum by providing an array of activities that are easy to implement and not supply-intensive and that are designed around sound pedagogical principles.
|Number of times to offer workshop:
||CHEM 280 & 283
||Thursday Morning [2010-08-05 07:40:00 - 10:30:00]
||2 lab spaces that can accomodate 50 people each would be ideal, but a large room with tables would be fine too.
||Not sure what this field is for.
We will be giving a few materials to the attendants:
- 3 grams of copper chloride dihydrate
- a 1" x 0.5" aluminum cylinder
- a generous amount of aluminum foil
- a plastic 50 mL graduated cylinder
- a 6" plastic ruler
||This workshop is appropriate for all levels of instructors, but is probably most appropriate for high school or first year college instructors.
Waste materials will be collected on site by the organizers and disposed of in coordination with the University of North Texas chemistry department. Waste will be primarily water, with small amounts of aluminum and copper.
||Supplies were priced and divided into a per-person cost for each item. Please let me (Dan Branan) know if you have any questions.
