NASA Launches Black Hole Hunter

NuStar

The space shuttle program may be discontinued, but that isn’t stopping NASA from plowing ahead with other space exploration initiatives. Case in point is the launch of the space agency’s Nuclear Spectroscopic Telescope Array (NuStar) high-energy X-ray telescope spacecraft.

The spacecraft’s mission is to get as close as possible to black holes and study them. Specifically, the NuStar will map radioactive material in supernovae remnants in an attempt to study the origins of cosmic rays and extreme physics surrounding collapsed stars.

The entire science community is eager to see the first high-resolution images that NuStar will take of the black holes, in addition to conducting a census.

Relevance--what's in it for me?

Greetings,

What's in it for me? That's a question we all ask when sitting in front of a teacher or speaker or someone who is taking upour time. It is also a question your students ask themselves constantly, and if you can't provide a strong answer, you can bet that you're going to have attention and discipline problems in the classroom.

So much of classroom discipline deals with keeping student in line through incentives, consequences and other techniques....

Should students be given weekly...

This week~ "Cooperative Learning 365~" an EducationWorld Facebook fan~ asks:


Should students be given weekly spelling tests?


ANSWER: First of all~ thank you for your question. Weekly spelling tests are a time-honored tradition in American elementary schools. For quite some time now~ however~ schools across the U.S. have elected to cut them out of their curriculum. Why? Because many education experts~...

Stopping the Fidgeting!

Being an observer in a classroom can be extremely enlightening or extremely frustrating. Students can be engaged in learning or engaged in what they are currently playing with in their desks. Unfortunately when a teacher is trying to teach 20 or more students at one time, that task may seem almost impossible because he or she is attempting to maneuver content, control large behaviors, and keep all students learning at the same speed.

Incentives in the Classroom. Do you use...

Some will say that teachers shouldn't offer incentives in their classroom, I am not one of them. I think just like adults appreciate being recognized for their efforts, it helps to have some type of incentive program in the classroom.

I used "Golden Tickets" which seemed to work well in my classroom. Students received 10 golden tickets for 90 above on quiz/tests), they received 3-5 golden ticket points for class participation ,3-5 points for...

Preparing Teachers for the Urban...

How can new teachers be prepared for the challenges of the urban classroom? College professor Dave Weiss, who taught for more than 30 years in Chicago, offers some personal suggestions in this week's Pulse blog post.
Some school districts have already instituted a one-year student teaching program. This allows the novice to experience the practicalities of beginning the first day of school and the end of the school year. This would be an excellent program if instituted...

Is it Time for a New Calendar?

Imagine, knowing that your birthday would always fall on the same day each and every year. Would it be helpful if you knew that all holidays would also be celebrated on the same day? Our current calendar, called the Gregorian calendar, has been used for 450 years. Two professors at John Hopkins University think we need a new calendar. Their calendar would eliminate all leap years, which are added ever 4 years to keep our 365.2422 day year from getting our calendar out of sorts. With the...

An Inexpensive Classroom Must-Have!

Starting off with something so simple, the first task to change your classroom to a haven of learning is to grab some Popsicle sticks from a craft store. It doesn't matter whether they are plain or colored. It doesn't matter whether they are skinny or fat. Your only purpose is to use them to write students' names.

Once you have your sticks, begin writing each student name on individual sticks until you have written down your entire roster. Be sure to include last initials of students...

Snowboarding Crow? Using current events...

Using current events in the classroom-new idea:
Love to snowboard? Seems a crow in Russia does, too. Caught on video, a hooded crow found a round plastic jar lid, perched it on a slope of the roof and repeatedly slide down. He didn't fly above the lid, he planted his feet on the lid and off he went, displaying play-like behavior.Scientists say crows are very intelligent and have great memories. On...

The More Things Change, The More They...

Editor's Note: This week's post comes from Dave Weiss, a college professor who teaches in the education department.
The title of this post can be applied to the state of teacher education today. When I did my teacher training, forty years ago, I was armed with Piaget, Bruner, Dewey, and other theories of learning. I found these theorists exciting and stimulating. I was ready to implement these theories when I would finally be given my own classroom. My goal was to teach in an...
