Flushing DNS Cache In OS X

From time to time, when changing DNS configurations you will need to flush the local DNS cache on your computer. On a Mac, this can easily be done from terminal. Just run the following commands for your respective version of OS X…

Mavericks (10.9)

dscacheutil -flushcache;sudo killall -HUP mDNSResponder

Mountain Lion (10.8) and Lion (10.7)

sudo killall -HUP mDNSResponder

Snow Leopard 10.6 and Leopard 10.5

dscacheutil -flushcache

Tiger (10.4) and Panther (10.3)

lookupd -flushcache

Socrative 2.0 Releases Tomorrow

logoSocrative is a great way to get real-time responses and assessment from anyone with a computer, smart phone or other mobile device. It gets its name from the Socratic Method, and is a great way to engage students in the classroom or lecture hall.

Socrative 2.0 is coming out Monday, October 7, 2013. This new version will include student quiz navigation, which allows them to skip questions and move to any question in student-paced quizzes, and the ability to include images in any multiple choice or short answer questions.

I am looking forward to participating in their Fall Partnership Program, providing detailed monthly feedback and being a part of forming this up-and-coming student response system.

There is an app for teachers and a separate app for students for iOS.

Did You Win?

Now that the school year is in full swing, there is a lot of action going on in the lives of students, parents, and teachers. Unlike in the summer, activities students do now are graded, judged, or critiqued—as it should be to a degree, but as adults we must always be mindful of how that can create a lot of pressure and can discourage a child.

One way this can occur is in the area of athletic competition. Now I am not going down the road of anti-competition where everyone wins (if you follow the previous link, please understand that it is satire), but we need to be careful, thoughtful, and encouraging.

Competition is good. Winning is good. Losing is good. Yes—losing is good.

Losing is good if a lesson can be learned from it. One of the most important things you can teach a child from losing is that their value is not tied to winning or losing. Rather than asking, “Did you win?”, try something different—”Did you have fun?” or even “How did you do?”—with the you being the singular, second-person pronoun.

These allow for conversations without a focus on the win or loss. You can talk about certain plays, personal improvement, and follow the conversation where it goes—giving you a chance to connect. Give it a try after the next game.

The Flipped Classroom Explained

One of the more recent buzzwords in education is the “flipped classroom.” It seems that in most conversations I have heard it in, people use it as a synonym for some kind of new technology in the classroom when in fact it is almost the opposite. While technology can—and should be—a component of the flipped classroom, it is not the pièce de résistance.

For example, knowledge and comprehension are often the focus within the classroom. We lecture, provide definitions, and assess the student’s comprehension through tests and quizzes. Application, analysis, synthesis, and evaluation are often left for students to work on independently outside the classroom in the form of projects and research papers.

When the classroom is flipped, the low-order thinking tasks take place outside the classroom through reading—or better yet—watching videos and online (or inline) assessments. This frees up time in the classroom for students to engage in the high-order thinking activities with direction and guidance from the teacher.
