This month under the guidance of Educational Technology Specialist Angela Minnick the students at Dahlgren School have become budding computer programmers. Taking part in the “Hour of Code” event, students at all grade levels took part in simple “GUI” or Graphic User Interface-based coding lessons that introduced them to the concept of programming. A GUI allows users to interface with a computer or other devices with graphical elements such as pictures or animations as opposed to using text based commands. This means a student doesn’t even have to be able to read yet to write simple programing, which was an important factor for Ms. Hibbeler’s kindergarten class who has just begun to learn sight words! The “Hour of Code” is a worldwide event that presents a one-hour introduction to computer science, designed to demystify code and show that anybody can learn the basics of computer programming. Non-profit organization “code.org,” along with
Computer Science Education Week, organized the event, now in its fourth year following their original online video that promoted computer science in 2011. That video became a YouTube sensation; it was the number one video for that day, and more than 15,000 schools contacted the organization for assistance to learn how to promote computer science and literacy for their own students of all ages. The goal of the program is not to create a computer phenom overnight, but to demonstrate that computer science is fun and creative and accessible to all regardless of age or background. “If we can plant that seed through this experience that programming is easily accessible and by both boys and girls of all ages, we have been successful,” Jeff Duncan, Dahlgren School principal shared. Duncan looked around the classroom at the sixth through eighth grade students each working on different programs, at different skill levels. “They are really excited about the program and it’s a perfect activity to introduce them to the concept,” he said. “Through the Hour of Code event, our students

Plus having the opportunity to create a program then have a classmate play the game is beneficial to them to see how this
could perhaps be a future career.” Minnick sees the Hour of Code event as a way to enhance the student’s sequential abilities and expand

Been Caught Speeding? By Barbara Wagner, staff writer If you have driven on Dahlgren road recently, chances are you have noticed members of Naval Support Activity South Potomac (NSASP) Security Forces training with a new piece of equipment — a LiDAR or LADAR, which is a Light or LAser Detection And Ranging handheld system. This new device will allow Police Officers to more accurately pinpoint individuals speeding on Naval Support Facility (NSF) Dahlgren and NSF Indian Head. “It was time,” Naval Support Activity South Potomac (NSASP) Chief Operations Officer Dave Frederickson said. “We have been utilizing analog technology in a digital world so to speak. Our old equipment was outdated; and it was becoming increasingly difficult to repair the units that were regularly breaking down. The new technology is much more efficient and accurate.” The new equipment is already in use on both facilities and tickets that

Dan Henderson shared. “We are utilizing it both on NSF Dahlgren and Indian Head and we have about 22 officers
trained to deploy the technology.” According to Sgt. Melvin Johnson, the officer in charge of training on the LiDAR, “Using the radar system wasn’t as accurate and you couldn’t pinpoint one particular vehicle. Using the LiDAR, drivers who have been caught speeding can’t use the excuse
that it was another car around them. Currently we have held two classes to train the officers on the equipment.” To be qualified to use the equipment the officers must take a class and pass a written test. Upon passing the test they must take part in a visualization exercise where the officers hone their skills at determining the speed at which a vehicle is traveling then check that with the new LiDAR equipment. To pass, the officers must be within three miles per hour of the actual speed. The officers must successfully estimate 25 vehicles in the daytime and 25 at night. Only then are they considered competent in the utilization of the equipment. “You have to be able to testify that you saw the vehicle speeding and confirmed the visualization with the LiDAR,” Johnson said, when asked why it is important for officers to be able to accurately assess speed by visualization.
