We all know how just the right lighting can set "the mood" -- whether you're aiming for a romantic ambiance, an energizing workout environment, or a dimly lit atmosphere to relax in. Now, a new study published in the journal Optics Express this week, suggests that dynamic lighting can support students' performance in classrooms. Researchers in South Korea found that lighting can be optimized for many various activities, from test-taking to recess to reading, and they characterized lighting by measuring their CCTs -- or different correlated color temperatures -- from "warm" to "cool" using the Kelvin scale. While the Korea Advanced Institute of Science and Technology research findings may seem obvious, they provide more evidence to support the argument that lighting can influence our well-being and that we can manipulate lighting to help improve our well-being, study co-author Dr. Hyeon-Jeong Suk, an associate professor at the institute, told The Huffington Post on Thursday. "Besides improving human performance, variable lighting CCTs also exert a great influence on both the physical and mental conditions of humans," Suk said.
This fall, as I have for nearly 29 years as an educator and academic advisor, I'll face freshmen engineering students who are certain of what they're going to do with the rest of their lives. Then they take a few classes, join some clubs, look around – and some will realize this is not what they expected and may not be what they want. Suddenly, all their preparation to follow a single, narrow path has done them more harm than good. Today's high school students are expected to decide on a life path early, and dedicate everything to pursuing that track. This is especially true for teens considering a STEM field, such as engineering or science, as they often use their high school experience to take all the STEM courses that will prepare them for college.
Students could sidestep traditional schools completely, though a report last year raised concerns about the performance of full-time virtual students. The report by the National Education Policy Center found that only about 37 percent of full-time virtual schools in the U.S. received acceptable performance ratings, and the average graduation rate was 43 percent.
This issue keeps plenty of online teachers up at night. It's an ongoing challenge to keep learners interested, on track, and motivated to complete their courses. And there are many strategic ways to do that. Each of these approaches can certainly make a difference. Many can actively reduce the drop out rate in your online training courses – over the long term.
The College Board made substantial changes in its redesign of the SAT. The exam still tests critical reading and math skills, but the essay portion is now optional. The redesign focuses more on areas of math that matter most for college and career readiness and shifts away from obscure vocabulary words that don't typically find their way into most high school or college classrooms.
