Less Smog, More Design

odd sculptureElegant Embellishments has created some groovy tiles that clean the air and add some aesthetic flair in cities. The tiles are still being developed, but this idea is really cool. The tiles are modular and can be mounted as a stand alone sculpture or attached to a building.

The technology behind the tiles is still being tweaked. Essentially, the tiles absorb pollutants that are generated from cars that lead to smog, while letting other gasses float on by. The tiles need to be located near the pollution source in order to be the most effective of course.

“The tiles provide councils, developers, and designers with an easy way simultaneously to improve the air quality and visual appeal of urban spaces. A London- and Berlin-based, interdisciplinary collaboration between innovators and materials manufacturers, architects and city councils, Elegant Embellishments produces lo-tech, interactive tiles in all shapes and sizes together with Millenium Chemicals TiO2. The tiles are modular and can thus be assembled to cover any surface or create any shape desired.”

No More Homework?

If research is to be believed, your kids may start coming home with less homework.  For younger students, a few schools are reducing the number of repetitive exercises given, and replacing them with assignments designed to engage the mind. 

Years of research supports the idea that there is no link between grades and the amount of homework assigned.  In a study covering 50 countries, students with the highest grades (such as Japan and Denmark) did very little homework, compared to children with the lowest grades (such as Greece and Iran), who did lots of homework.  Due to various research reports, some teachers and parents now see no need to assign a lot of afterschool work in the early and middle grades. 

Harris Cooper, one of the leading researchers on homework in the United States, firmly believes in extra schoolwork.  “Kids at all grade levels are going to benefit from practice,” he states.  “…If it’s practice that gets you to Carnegie Hall, homework’s going to help.”

However, he acknowledges that too much does not mean better grades.  His rule of thumb: children shouldn’t do more than 10 minutes of homework for each grade.  For example, a Grade 2 student should have only 20 minutes of homework; a Grade 7 student, 1 hour and 10 minutes.

At Vernon Barford Junior High in Edmonton, teacher Judy Hoeksema now assigns half the work she did last year.  “We’ve all been under this illusion that lots of homework creates good study habits for the future,” the math teacher of 26 years says.  “Now, we’ve realized it isn’t making much difference.”

As a bonus for scaling back homework, many families are seeing  increased quality time for children and parents , less household stress, and less physical stress on their kids due to less books being carried.
