aspectj.org: Crosscutting Objects for Better Modularity
AspectJ is a Java extension with aspect-oriented functions and programming technology. Continuing with the open source movement, the developers have made AspectJ free for download from this Web site. The software implements "the clean modularization of crosscutting concerns" like performance optimizations, debugging support, and more. The compiler, several accompanying tools, and example programs are all provided in the release. There is also extensive documentation and a tutorial to help new us
MIT Space Systems Laboratory
Massachusetts Institute of Technology (MIT) created the Space Systems Laboratory (SSL) in 1995 to engage in "cutting edge research projects with the goal of directly contributing to the present and future exploration and development of space." Users can find materials on current and past flight projects such as the Synchronized Position Hold, Engage, Reorient Experimental Satellites (SPHERES) and the Interferometry Program Experiment (IPEX). The website also features SSL's ground programs and re
Learning math : Measurement
This college level course, developed for elementary and middle school teachers, begins with the fundamentals of measurement, then examines standard units in the metric and customary systems. Online workshop sessions cover measurement of a circle, area and volume formulas, angle measurement, and indirect measurement encountered in trigonometry. The final session explores ways to apply these concepts to K-8 classroom teaching. Each of its ten sessions contains video programming, problem-solving ac
Looking at the sky through a glass ceiling : women in astronomy
This article looks at the involvement and acceptance of women in astronomy. Before introducing readers to three significant female astronomers from the 1900s and three from the present day, the article mentions the work of the first known female astronomer--Aglaonike from 200 B.C. Statistics are also provided concerning contemporary women's participation in astronomy. The three astronomers featured from the 1900s are Henrietta Swan Leavitt, Cecilia Payne-Gaposchkin, and Jocelyn Bell Burnell. Eac
Who Needs Algebra? Everyone! : Northwest Teacher, volume 6 number 1
Learning algebra doesn't have to be painful, and researchers are finding that the process is easier if children are introduced to algebraic reasoning early on. This issue of NW Teacher points out that students who begin learning algebra at the elementary level have a stronger foundation for higher-level mathematics. Algebra also helps pave the way for college and increased career opportunities. This issue helps schools explore new ways of bringing algebra to all students.
