using the Exploring the Environment® (ETE) modules and activities will
become competent in a number of technological and thinking skills.
students collect, analyze, generate, and transmit information through
computers. They use e-mail to communicate their findings to ETE students
at other schools and to contact scientists for answers to questions. Students
also learn specialized software products and interpret remotely-sensed
images. Students use computers to search the Internet for information
that will help them to develop satisfactory solutions to the problems
they are trying to solve. Finally, students use word-processing software
or hypertext mark-up language (html) to create a report to present their
findings, solutions, or recommendations.
Learning in Collaborative Learning Groups
online series emphasizes problem-based learning (PBL) and collaborative
learning groups for student-directed inquiry into Earth systems education.
The modules encourage students to think, to solve problems, and to write
and speak clearly. The emphasis in this PBL model is for students to take
responsibility--and a more active role--in the learning process. And as
in real ife situations, the goal is not necessarily in answering questions
correctly, but in asking them. To learn more about using PBL and cooperative
learning, there are useful tips in the Teacher Pages.
and associated agencies hold terabytes of remote sensing data in databases
that can be effectively used to support educational activities over the
Internet. The purpose of the ETE series is to develop and provide middle
school and high school environmental Earth science modules that feature
NASA's remote sensing information.
satellite images used in ETE modules are images of the earth taken from
NASA satellites or aircraft, which students download from the Internet.
The images, however, are not taken by ordinary cameras, and they may
vary from traditional photographs in many ways, especially in color and
scale. Interpreting them may involve physical manipulation (cropping,
rotating) or mathematical manipulation (processing) of the digital data
stored in the pixel array of the image. These manipulations are done in
the classroom by students using image processing software. Students access these software
products by following instructions in the ETE modules.
