PhET Lab experiments represent real interactive, and research-based simulations of physical phenomena from the PhET™ project at the University of Colorado. For teachers and students around the world, the PhET project provides interactive simulations that are based on extensive education research and support more effective science education. Going beyond traditional educational resources, PhET simulations offer an intuitive, game-like environment where students can learn through scientist-like exploration, where dynamic visual representations make the invisible visible, and where science ideas are connected to real-world phenomena. Unlike most educational software, PhET simulations are free, easily translated into multiple languages, and available either online or offline, especially important for areas with poor or no internet connectivity. With their flexible design, the simulations can be used in many ways - as demos, homework, or inexpensive yet accurate and realistic lab alternatives. Explore a few of the PhET Labs simulations on several Science disciplines:
ALEKS - Assessment and LEarning in Knowledge Spaces is a Web-based, artificially intelligent assessment and learning system. ALEKS uses adaptive questioning to quickly and accurately determine exactly what a student knows and doesn't know in a course. ALEKS then instructs the student on the topics she is most ready to learn. As a student works through a course, ALEKS periodically reassesses the student to ensure that topics learned are also retained. ALEKS courses are very complete in their topic coverage and ALEKS avoids multiple-choice questions. A student who shows a high level of mastery of an ALEKS course will be successful in the actual course she is taking. ALEKS is a web-based system used in determining the preparation, placement and assessment of in-coming students in Math for upper division courses. This online program can also be used in determining student's preparation for upper level courses in the science disciplines. The program is able to diagnose and adapt to a student's developing knowledge and skills, and provides precise feedback when mistakes are made. The student proceeds with learning a new topics when mastery is achieved from prior subject assessment. ALEKS is inexpensive - and no site-licensing is required - only an access code purchased by the student for a nominal fee. Explore the features of ALEKS.
