Cooking Up a (Virtual) Laboratory: Discovery Education Science Delivers
These digital resources, from interactive glossaries to lab simulations, help teachers engage students. By Maya Payne Smart Click here to view the story on Edutopia.org. In an ideal world, teachers would engage students one-on-one and
foster a learning environment that's as dynamic and promising as the
kids themselves. They would present lessons with panache, assess
student comprehension along the way, and give kids a chance to apply
their newfound knowledge immediately. Classes would inspire students at
all levels to explore topics more deeply and allow them to pursue their
curiosity independently.
Some teachers say this Edutopia is now a little easier to implement in the classroom
thanks to Discovery Education Science for Elementary,
a digital service from the company behind the Discovery Channel.
Education experts have carefully vetted and organized the service's
e-books, reading passages, video clips, virtual labs, interactive
glossaries, and other materials. The result is a suite of resources,
available for a yearly subscription fee of $1,695 per school, that
teachers can use to engage students with diverse interests, knowledge,
aptitudes, and learning styles in the earth, life, and physical
sciences. A similar service, Discovery Education Science for Middle School, costs $1,995 per year per school.
Lessons for EveryoneEmma Haygood, a science and technology instructor at Berrien Springs
Middle School, in Berrien Springs, Michigan, says Discovery Education
Science levels the playing field for students, giving everyone an
opportunity -- and an enticement -- to learn. "We don't have a lot of
money for materials and supplies," she says. "The service offers a lot
of interactive labs the kids can work on that I wouldn't otherwise be
able to have in my classroom. And because it's on the computer, makes
noise, and is interactive, they think it's the greatest thing."
Haygood says the service reduces the pressure on students who have
disabilities, are slower to pick up new concepts, or have missed class
due to illness. Discovery Education Science has organized its reading
passages by grade level, so teachers may pull different reading
passages for special education or struggling students.
Its e-books have audio support as well, so students can listen to
the text as they read along. Many videos are closed captioned, which
helps hearing-impaired students. And if students are sick, they can log
in to the service from home with a teacher-provided password to cover
missed material. On the flip side, the service gives advanced students
access to selected middle school-level resources for additional
learning.
The service also helps teachers respond to the inevitable
assemblies, snow days, and other intrusions that cut class time short.
"I can say, 'Scrap what we were going to do, and let's do this
instead,'" Haygood notes. "You can go into it, and you don't have to
make any modifications."
Teachers can evaluate their students' mastery of key concepts via
online assessments that the service automatically scores and exercises
that teachers can grade with the help of a scoring tool.
Here's an introduction to some of the key features teachers can use
to supplement traditional classroom instruction, demonstrations, and
experiments in elementary-level science courses:
Interactive GlossaryKnowing vocabulary is critical to student performance in the
sciences, so Discovery Education Science for Elementary features an
interactive glossary that puts words into context. For example, it goes
beyond blandly defining the term mineral as a "natural,
nonliving solid crystal that makes up rocks." Accompanying images
reinforce the definition. An animation zooms in on a photo of a quarry
to focus on a granite rock before delving deeper to reveal its
constituent minerals: feldspar, mica, quartz, and hornblende. A video
takes the lesson further by repeating the basic definition and then
showing minerals in daily life -- the salt we eat, the gypsum in
building materials, the clay we mold, and the gold we wear.
MultimediaTracie Belt, a life science teacher at Shorecrest Preparatory
School, in St. Petersburg, Florida, says Discovery Education Science's
reading selections, image library, and video clips make it easier to do
integrated curriculum projects that connect language arts, history,
technology, and science. If her students are learning about American
colonial times in history class, for example, she might assign readings
and videos about diseases from that period. The students can then use
the service's movie clips to make an Apple iMovie,
read about the discovery of germs in articles and e-books, or write
papers or give presentations based on what they've learned.
"The new method of teaching is trying to get kids to think, and this
is the best tool I've ever used for doing just that," Belt says.
Discovery Education Science brings all of the digital resources
together in one place so students can navigate through them at their
own pace and make decisions about the information, images, or video
clips they will incorporate into their work. Moreover, they can do all
of this independently.
"I think it is really important, because twenty-first-century
teaching is all about collaboration," Belt explains. "I don't want collaboration to mean just group work; I need projects in which all students have a part,
but they are individually accountable."
Virtual Labs and ExplorationsVirtual labs allow students to explore and experiment. When they
change a variable in a digital simulation, they can see the results of
those alterations more quickly -- and in many cases, more safely --
than in a traditional lab. Without risk of injury, students can apply
what they've learned in class and test their hypotheses.
In one virtual lab, students can investigate how differences in
soil, water, and light affect the growth of various plant types.
Another lab makes students marine engineers and uses their knowledge of
shape, volume, and mass to explore what makes objects sink or float as
they design and build virtual submarines for exploration under the
ocean.
"In a lot of science classes, you can't do the lab, because it's too
expensive, you don't have the time, or you don't have the space," Belt
says. "The simulations still stimulate their thinking and allow them to
test their predictions."
However, the virtual labs and inquiry-based explorations of topics
are not meant to replace more traditional experimentation. "Hands-on
work is critically important," says Robert Onsi, vice president of
product management for Discovery Education. "But if you take hands-on
experimentation and marry it with digital resources, then you really
have something special." Many teachers agree.
