In our rapidly moving culture, special education students, diagnosed with ADD or ADHD (Attention Deficit Disorder or Attention Deficit Hyperactivity Disorder) are an ever-increasing challenge for teachers. Having taught in some capacity for nearly 40 years and being a parent of an active little boy, I have studied these conditions with immediate personal interest.
Holding Their Attention
Early in my work with the attentionally challenged, I observed that if the learning activity were engaging enough, many of these students could hold attention for long periods. Special Education students diagnosed with ADD or ADHD often have the ability to attend for long periods working with computers or video games. I wondered, could the problem lie more in the pace of the learning activity?
Give Them What They Need
Subsequently, I began to provide activities in my classroom that had some of the same qualities of the immediate response achieved in those computerized attention-holders. One of the most successful of these was the excavation of fossils.
Fossil excavation was a 6-week class – more of a club, really in which students excavated a real fossil fish from a soft rock matrix. This time the class was made up of many special education students with various learning challenges, especially ADHD. The outcome of the class was remarkable.
Getting Their Interest and Attention
We started with a sort of guessing game involving fossils hidden in velvet bags and moved quickly into individual excavation of the fossils. Within minutes, my work was done; the students worked independently for the remainder of the two-hour class. My hardest work that day was to enforce clean-up-the students simply didnt t want to stop working.
Tools And Supplies
The only tools needed for this activity were small screw drivers-the sort that are available from any hardware store in a set of increasing sizes beginning with an eye-glass tool . I also provided magnifiers of varying types. The most sought after were the dissecting microscopes, which gave the individual the best view of the fragile fossil. However, much of the work could be easily accomplished using the naked eye or a magnifier in a stand, just to leave the hands free.
And Then There Are the Behavioral Challenges
I was presented with a new challenge about halfway into the second class: a behaviorally disruptive student who had been removed from another class. I did what I could to introduce him to our work and bring him up to speed. His initial work was little more than digging a hole through his rock, paying little attention to the fossil it contained.
Then a wonderful thing happened. Another boy, a challenging special education student who generally had little academic success, began to teach. You see, this boy was enthralled with digging out the fossil and he was having incredible success. He single-handedly took over and my work was done.

On Monday, Symbian Foundation discontinued Symbian OS, as a result of its lost popularity since Android came to market. The Finnish telecommunications company Nokia, being one of the few hardware manufacturers who use the system on some of the models, announced that it has taken over the operating system’s development.
Nokia had acquired Symbian Foundation in 2008. Now, the foundation refused to continue the project, because this smartphone operating system had lost its popularity when Android came to market. During the next several months, most Symbian Foundation employees, who were completely governing the project previously, will retire. By April 2011, only the licensing team will stay to oversee the project.
The executive director of the Symbian Foundation Tim Holbrow explained the change, saying that “There has since been a seismic change in the mobile market but also more generally in the economy, which has led to a change in focus for some of our funding board members. The result of this is that the current governance structure for the Symbian platform — the foundation — is no longer appropriate.”
Instead, Nokia takes over the development of the system. This is possible because the Symbian OS is currently open source and freely redistributable. In an interview with ZDNet, the head of Nokia smartphone business Jo Harlow said that the takeover was in significant part because Nokia hardware was the major one using the OS. The development environment would be switched to Qt framework for the system to support cross-platform applications use and development. It is unclear whether the licensing of the future releases of the system would remain open-source.

Fifty James Logan High School seniors are scheduled to take the California High School Exit Exam today and tomorrow, while an Oakland judge is preparing to strike down the law requiring would-be high school graduates to pass the high-stakes test.
Alameda County Superior Court Judge Robert Freedman said Monday that he will make his final decision today at 2 p.m. PDT on whether to issue an injunction against the enforcement of the law requiring the exam’s passage, citing “equal protection” concerns.
The ruling would affect about 47,000 California high school seniors, and dozens at James Logan High School, who have yet to pass the exam and would be barred from being graduated if they don’t.
Last week, state schools Superintendent Jack O’Connell released new statistics showing that 46.768 seniors, or 10.7 percent of the class of 2006, still haven’t passed the test.
Sixty-one percent of those students are poor, and 44 percent are English learners.
Of the 50 James Logan students taking the test today and tomorrow, 35 speak English as a second language. Eight are special education students. Of the five black students taking the test, four are special education students. Of the three white students taking the test, two are new to the district and the other is a special education student.
One, an Asian immigrant, has a 3.67 grade-point-average.
O’Donnell wrote the law requiring the test when he was in the state legislature in 1999.
In a statement to the press, O’Donnell said “Recognizing that today’s ruling is not final, I intend to do everything in my power to ensure that at the end of the legal day we maintain the integrity of the high school exit exam,” O’Connell said.
Gov. Arnold Schwarzenegger said “delaying the exam’s implementation does a disservice to our children by depriving us of the best tool we have to make sure schools are performing as they should be.”
He said he was “disappointed.”
The attorney who sued the state Feb. 8, Arturo Gonzalez of the San Francisco law firm Morrison & Foerster, “felt strongly that the state should not deprive a student of a diploma unless the state can say that every student has been fairly and properly prepared for that test,” he said. “There is overwhelming evidence that students throughout the state have not been taught the material on the test. And many students have been taught by teachers not credentialed in math and English.”
The suit, was brought on behalf of lead plaintiff Liliana Valenzuela, a Richmond High senior who maintains a 3.84 grade-point average and is ranked 12th out of 413 in her class. Valenzuela has passed the math portion of the exam, but not the part on English, which she speaks as a second language.
Gonzalez contends the test is unfair, particularly to English learners, because students who have failed the test repeatedly are more likely to attend overcrowded schools with less-qualified teachers.
Judge Freedman said he was persuaded by that argument, but wanted to give the state a chance to change his opinion.
He asked lawyers on both sides to come prepared to talk about how conditions in the schools can be equalized.
Gonzalez urged seniors who still need to pass the test to keep going to classes and studying. “It is absolutely critical for students to understand that even if the order is made final, only those students who passed their classes will get a diploma,” he said.

Mars rover engineers have built a test bed simulating the condition of the Mars Rover Opportunity, which became stuck in a Martian sand dune on April 26. The test bed uses a combination of materials including play sand for children’s sandboxes, diatomaceous earth for swimming pool filters, and mortar clay powder.
Opportunity dug into soft sand to wheel-hub depth as it drove over a dune about one-third meter (one foot) tall and 2.5 meters (8 feet) wide. “We’ve climbed over dozens of ripples, but this one is different in that it seems to be a little taller and to have a steeper slope, about 15 degrees on part of its face,” said Mark Maimone, a Jet Propulsion Laboratory (JPL) rover mobility engineer. Tests will be conducted using an Earth-bound twin of the rover and the simulated Martian dune to determine how to best maneuver Opportunity out of the predicament before transmitting commands to the actual vehicle.
“We choose to proceed cautiously, so we don’t expect to begin actually driving out of the dune before next week, possibly later,” said Jim Erickson, rover project manager at JPL. “Both Opportunity and Spirit have already provided many more months of scientific exploration than anyone expected. By taking good care of them, we hope to keep them exploring for more months to come. Tests so far have sustained our optimism about Opportunity’s ability to drive out of this dune, but we have more testing ahead to understand how robust that capability is.”
Engineers constructed a simulated dune last week using sand that was already at JPL’s rover testing facility and put a test rover into a similar dug-in position. The test rover had no difficulty driving away, even when sunk belly-deep. However, that sand offered better traction than the finer, looser material that appears to make up the surface at Opportunity’s current position. “We needed to do tests using material more like what Opportunity is in, something that has a fluffier texture and cakes onto the wheels,” said JPL rover engineer Rick Welch, who is leading the tests.
Based on images of wheels and wheel tracks from Mars, Dr. Robert Sullivan of Cornell University, a rover science team member, working with engineers in the JPL test bed, helped match the properties of the test sand as closely as possible with those of the sand beneath Opportunity, “We found that when the wheels dig in, the material we’re using does stick to the wheels and fills the gaps between the cleats, but it doesn’t stick when you’re just driving over it. That’s good because it’s the same as what we see in the images from Opportunity,” Sullivan said. Experiments show that the test rover, after some initial wheel-spinning, can drive out of the more powdery material.
The team went to several home supply and hardware stores to find enough bags and boxes of the ingredients to make more than 2 tons of the simulated Mars sand for the more realistic mobility tests, according to JPL rover mobility engineer Jeff Biesiadeckia.

Pichilemu, Chile – Last Saturday, Chile was hit by a 8.8 earthquake. Many coastal towns were also hit by a tsunami, and Pichilemu was one of them. Its inhabitants were surprised by the giant waves that destroyed the most of the costanera and that reached the city square.
Pichilemu, that means in Mapudungun language small forest, is one of the most famous Chilean resort towns in the central zone of Chile. It is recurrently visited by surfers from all the world, because the Punta de Lobos beach is considered one of the best for surf practice worldwide.
Central Pichilemu was not severely damaged by the earthquake, but the tsunami caused significant destruction. The Fishermen Creek, located in front of the beach, was completely destroyed, and its machines are now unusable. Most of the Agustín Ross architecture that characterized the city, three of them being National Monuments of Chile, were damaged. The Agustín Ross Mirador, a famous location in front of the beach, located less than 200 meters from the Fisherman Creek, was completely destroyed. Its famous balustrades were washed away or thrown asunder. Many restaurants, kiosks and a circus were affected by the tsunami.
The rural parts of Pichilemu, like Ciruelos, Rodeillo and Espinillo feature houses constructed from adobe. Many were more than 100-years old, and were destroyed or are now uninhabitable.
The most powerful aftershock was produced almost 40 kilometers in front of the coast of Pichilemu, at the 03:10 local time (07:10 UTC) in March 2, with an intensity of 5.5 in the Richter scale, according to the USGS.
The Intendant of the O’Higgins Region, Juan Núñez, had a meeting with the Governor of the Cardenal Caro Province, Loreto Puebla, the Mayor of Pichilemu, Roberto Córdova, and naval and military authorities, juntas de vecinos representatives. They decided to leave the Carabineros police force to maintain the security of the city.
The Arturo Prat square was severely damaged by the earthquake and later by the tsunami. In the left picture, can be seen some kiosks, all of them were destroyed, as can be seen on the right picture.Image: Diego Grez.

Regional U.S. telephone giant SBC Communications is one step closer to offering cable television to the 18 million households in its 13 state coverage area. The company announced a $195 million contract with Scientific-Atlanta Thursday to provide a video operations center and regional hubs for the new service. Under the brand name, U-verse, the SBC’s television rollout is set to launch in 2006 after field trials begin later this year.
The company is seeking the so-called “triple play,” where a telecommunications company offers voice, data and video in one bundled package. Local telephone companies like SBC have been losing business to cable TV companies, which have added telephone and Internet services in recent years.
In a slew of recent deals, SBC is looking to stop that trend. Within the past six months it has signed alliances with various technology firms to build out a fiber network to the home strategy. For instance, SBC has a $1.7 billion deal with Alcatel to build out its fiber optic network and a 10-year, $400 million, pact with Microsoft to license its IPTV technology to allow multi-channel television to stream over its Internet backbone.
In most of the U.S. only cable TV companies like Comcast have been able to offer the “triple play” of voice, video and data services. But traditional phone companies like SBC and Verizon have been upgrading their copper wire telephone networks to fiber optic. SBC says it plans to spend billions of dollars to overhaul its telecommunications network, saying the aging and brittle copper wires which were originally laid in the early 1900s do not have enough bandwidth to allow television capability.

Basics Of Microwave Ovens
Microwave ovens or microwaves are kitchen appliances that using the technique of dielectric heating for cooking or heating food. Most microwaves of today have features like grill and convection system, toaster slots, defrosting facility, steam-cleaning features, child safety lock, power-saving features and the like.
Advantages Of Microwave Ovens
These days, microwaves are becoming an important part of every kitchen. It has started replacing many other appliances due to its versatility. Microwave has its own merits that make them the most preferred choice. These features are:
They help to retain the flavor and taste of the food cooked.
They are quite cost efficient and safe to use.
Microwave ovens do not require being pre-heated unlike the traditional ovens and can be used for cooking without any delay once switched on.
Cooking in microwaves avoid the heating up of the surroundings as with gas stoves which makes the kitchen area hot.
Microwave cooking helps to overcome the odors produced while cooking.
The stains caused by food spills on the kitchen table and walls are prevented when using microwave ovens for cooking.
Microwaves do not need to be washed regularly as gas stoves. They can be just wiped with a damp cloth to remove dirt and food particles.
Cooking food is faster and requires less effort especially if using dual ovens which have the features of a conventional and microwave oven.
Disadvantages Of Microwave Ovens
Like with any other kitchen appliance, microwaves too have some demerits. However, the merits definitely outweigh the demerits.
There are chances of the food getting over cooked or unevenly cooked.
All types of utensils cannot be used for cooking in microwave ovens. Microwave-safe containers and vessels should be used for cooking.
Certain kind of food cannot be used for cooking in a microwave oven.
Since microwaves heat things quickly, it is not safe to heat liquids as they can be superheated leading to explosions.
There is a high risk of steam blasts in the microwaves which is caused due to tight covering of containers.
Tips For A Safe Microwave Cooking
Following some tips that ensure safe cooking with the microwave ovens:
Never cover the containers used for microwave cooking tightly as it causes pressure to build up inside the containers leading to steam blasts.
Never open containers immediately after cooking.
Never take out heated containers soon after cooking from the microwave. This helps to cook the food properly and also allows the steam to escape. Allow them to cool for sometime before removing.
Never heat liquids for more than two minutes. When heating liquids, it is advisable to put a wooden stick in the container to prevent super heating of the liquid.
Never reheat a warm liquid again in the microwave as it can lead to faster super heating.
It is advisable to read the instructions on the microwaves manual before cooking. They provide the necessary details regarding safe cooking with microwave ovens.
Never allow children to operate a microwave by themselves. Proper adult supervision is required to prevent any accidents.
are durable kitchen appliances that serve as a fast and healthy mode of cooking. There are several
microwave oven uses
that make it an indispensable proposition for food enthusiasts.

Israeli military forces today seized a ship claimed to be carrying weapons bound for the Gaza Strip.
The ship, a German-owned and Liberian-flagged freighter named Victoria, had departed from a port in Syria before travelling to Turkey, from where it departed for Alexandria, Egypt. A French company had chartered the vessel, which was intercepted and boarded by Israeli commandos about 200 miles from shore while in international waters.
Victoria was reportedly boarded without incident, and is being taken to Ashdod, a port city in Israel. Three containers of weapons were found on board the ship, though the type or total number are unknown. A further inspection of the cargo will be carried out once the ship reaches Ashdod.
According to Benjamin Netanyahu, the Israeli prime minister, “[o]n the boat we discovered many weapons destined for terror groups in the heart of Gaza.” He also claimed that Iran was responsible for shipping the weapons, saying that “[t]he only certain thing is the source of the weaponry was Iran, and there was a Syrian relay station as well.”
