Expii.com is a free interactive website focused on math and science, where students, teachers, tutors, and enthusiasts are encouraged to add their voices and teaching styles to the canon of problem-solving lessons hosted on the site. Each topic on Expii is built to support multiple explanations to help learners build deep knowledge by connecting with others who offer explanations that make sense to them. The multiple-explanation feature not only allows and adapts to several different learning preferences but also encourages students to add their own voice to the discussion. The Expii Solve section of the site poses thought-provoking, interactive mathematics problems that relate to current events and pop culture. Students can select from a wide range of theme-related math sets, such as Oscars, March Madness, Pi Day, and Climate Change. Each set has five problems that vary in difficulty. Students can get instant feedback while they’re working on their solutions. If they need help, students can follow the links to tutorials at the bottom of the page. After solving a problem, students can see others’ solutions and share their own. Expii was founded by Po-Shen Loh, a mathematics professor at Carnegie Mellon University and national coach of the US International Math Olympiad team.
Since 1983 the Presidential Awards for Excellence in Mathematics and Science Teaching (PAEMST) have been recognizing excellent educators spanning all corners of the countryâfrom one-room schoolhouses in rural Montana to large school systems in the heart of New York City.
MathWorks Math Modeling (M3) Challenge spotlights applied mathematics as a powerful problem-solving tool and as a viable and exciting profession. Participating students are encouraged to explore and bolster their mathematical modeling knowhow to position themselves for success.
