Back to School: Enhance Your Knowledge of Physical Science Register to attend the NSTA Online Short Course: Energy For grades 3–9 teachers, Energy, NSTA’s online short course, offers a painless refresher in physical science concepts, available directly from your computer this fall. The short course combines asynchronous learning with live web sessions to help you master this science content. Beginning September 30, participants will meet on five consecutive Tuesday evenings (September 30, October 7, 14, 21, and 28) under the guidance of Don Boonstra, an educator with over 30 years of experience in providing professional development for science teachers. For an hour and a half each week, attendees will join online in the virtual classroom with the instructor and NSTA staff to ask questions and have discussions about the topic. Follow up weekly participation in the discussions posted on the course listserv, and self-paced completion of corresponding course materials (SciPack, SciGuide, e-book, and journal articles) all contribute to boosting your knowledge of the subject. An elementary teacher with 24 years of experience who attended from Florida said, “Being able to ask questions through the chat window throughout the presentations and having my questions answered so quickly was very helpful. I liked working with and learning from the other participants. The presenter was very knowledgeable both about energy and how to effectively present it to students.” A comment came from a first year, high school teacher from Wisconsin after completing the course. “This was a great opportunity for me. I'm a life science major and never learned the specifics of energy. [The online course] helped a lot in understanding [the physical science concepts] as well as my new area of teaching, Earth science!” Fees include all materials: Member rate: $322.50 Nonmember rate: $367.00 Two graduate professional development credits from the University of Idaho can be earned for an additional fee.
