COLUMBIA, Mo. In her 16 years teaching algebra, Amy Dwiggins has seen countless students struggle with the seemingly abstract subject.
But the creation of new, online professional development materials at the University of Missouri could help teachers like Dwiggins, who teaches Algebra 2 and Geometry at Macon High School in Macon, Missouri, teach their students more effectively. Algebra can be a tough subject to learn if the students don t find it applicable to their daily lives, Dwiggins said. But we use critical thinking and problem-solving skills all the time, and math is a big part of that. So we, as teachers, need to find creative ways to spark students interests in a way that makes them more motivated to learn.

Underground pipelines that transport oil and gas are very important engineering communications worldwide. Some of these underground communications are built and operated in earthquake-prone areas.
Seismic safety or seismic stability of underground pipelines began to be intensively studied since the 1950s.
Since then, a number of methodologies were proposed for calculating stress received by an underground pipeline during an earthquake. The purpose of these methodologies was to make an accurate prediction on the structural stress received by a pipeline during an earthquake, and thus it would allow to decide how resilient the pipeline must be made in the first place. It is important to find a right balance between pipeline cost and its stru
