Oregon State University Study Documents Invasive Species Release by Science Teachers

Posted: Monday, October 1st, 2012

by Judith Aquilar

Oregon State University recently released their findings of a study conducted regarding the introduction of invasive species by science teachers. It was presented on August 7, 2012 at the National Meeting of the Ecological Society of America. The study surveyed 2000 teachers from Florida, New York, Indiana, Illinois, Oregon, Washington, California, Connecticut, British Columbia, and Ontario and included focus groups and interviews with teachers, curriculum specialists and biological supply house owners and managers.  The researchers found that one out of four educators who used live organisms in their classrooms released them into the wild after they were done using them. Some of the organisms included crayfish, elodea, amphibians, and mosquito fish.

For example, crayfish are often used to teach students about habitats and adaptation, and Elodea can be used to provide food and shelter for the crayfish. These organisms are popular to allow students to observe the behaviors of the crawfish as well as their structure and the function. It seems like a fantastic idea for inquiry-based learning in an elementary classroom.  Unfortunately, however, the study found that teachers in Oregon stopped using the native Pacific Northwest crayfish due to their high mortality rate and instead began to order their crayfish from Louisiana. If these non-native Louisiana crayfish are eventually released into the wild, this poses a problem because they are not an indigenous organism if released into a local Pacific Northwest lake or stream and the diseases or parasites they carry are unknown.

The NSTA Position Statement for the Use of Live Animals specifically states that if used teachers must “refrain from releasing animals into non-indigenous environs.” Unfortunately, though, sometimes teachers don’t give this issue much thought. Oregon State University expert on invasive species, Sam Chan, advises teachers and suppliers to become educated about the introduction of invasive species. So what should teachers do? The easiest answer is probably to rely only on reputable sources for organisms, and use native species whenever possible. Plan ahead for care or disposal of the organisms once you’re finished with them in the classroom. If in doubt, there are resources available to help you decide the best option. These include:

Finding My Student’s Motivation of Learning Through Engineering Tasks

Posted: Wednesday, July 12th, 2017

by Huda Ali Gubary and Susheela Nath

It’s 8:02 and the bell rings. My students’ walk in and pick up an entry ticket based on yesterday’s lesson and homework. My countdown starts for students to begin…3, 2, 1. Ten students are on task and diligently completing the work, twenty are off task with behaviors ranging from talking up a storm with their neighbors to silently staring off into space. This was the start of my classes, more often than not. My students rarely showed the enthusiasm for a class that I had eagerly prepared for. I spent so much time searching for ways to get my students excited about the concepts they were learning. I wanted them to feel a connection to the lessons and come into my class motivated about what they were going to learn next. I would ask myself how I could make my class memorable where the kids were in the driver’s seat of learning. Incorporating engineering made this possible. Learn More…

Teaching Science in the Time of Alternative Facts – Why NGSS Can Help (somewhat)

Posted: Wednesday, July 12th, 2017

by Peter A’Hearn

The father of one of my students gave me a book: In the Beginning: Compelling Evidence for Creation and the Flood by Walt Brown, Ph. D. He had heard that I was teaching Plate Tectonics and wanted me to consider another perspective. The book offered the idea that the evidence for plate tectonics could be better understood if we considered the idea that beneath the continent of Pangaea was a huge underground layer of water that suddenly burst forth from a rift between the now continents of Africa and South America. The waters shot up and the continents hydroplaned apart on the water layer to their current positions. The force of the movement pushed up great mountain ranges which are still settling to this day, resulting in earthquakes along the margins of continents. This had happened about 6,000 years ago and created a great worldwide flood. Learn More…
