Principies for an effective informatics curriculum
The committee performed a comprehensive review of the considerabie existing material on building informatics curricula, including among many others the (UK) Royal Society report, the CSPrinciples site, the Computing at Schools Initiative, and the work of the CSTA. Two major conclusions follow from that review.
The first is the sheer number of existing experiences demonstrating that it is indeed possible to teach informatics successfully in primary and secondary education. The second conclusion is in the form of two core principies for such curricula. Existing experiences use a wide variety of approaches; there is no standard curriculum yet, and it was not part of the Committee's mission to define such a standard informatics curriculum for the whole of Europe. The committee has found, however, that while views diverge on the details, a remarkable consensus exists among experts on the basics of what a school informatics curriculum should (and should not) include. On the basis of that existing work, the Committee has identified two principies: leverage students' creativity, emphasize quality.
Leverage student creativity
A powerful aid for informatics teaching is the topic's potential for stimulating students; creativity. The barriers to innovation are often lower than in other disciplines; the technical equipment (computers) is ubiquitous and considerably less expensive. Opportunities exist even for a beginner: with proper guidance, a Creative student can quickly start writing a program or a Web Service, see the results right away, and make them available to numerous other people. Informatics education should draw on this phenomenon and channel the creativity into useful directions, while warning students away from nefarious directions such as destructive "hacking". The example of HFOSS (Humanitarian Free and Open Software Systems) shows the way towards constructive societal contributions based on informatics.
Informatics education must not just dwell on imparting information to students. It must draw attention to aspects of informatics that immediately appeal to young students, to encourage interaction, to bring abstract concepts to life through visualization and animation; a typical application of this idea is the careful use of (non- violent) games.
Foster quality
Curious students are always going to learn some IT and in particular some programming outside of informatics education through games scripting, Web site development, or adding software components to social networks. Informatics education must emphasize quality, in particular software quality, including the need for correctness (proper functioning of software), for good user interfaces, for taking the needs of users into consideration including psychological and social concerns. The role of informatics education here is:
• To convey the distinction between mere "coding" and software development as a constructive activity based on scientific and engineering principies.
• To dispel the wrong image of programming as an activity for "nerds" and emphasize its human, user-centered aspects, a focus that helps attract students of both genders.
Breaking the teacher availability deadlock
An obstacle to generalizing informatics education is the lack of teachers. It follows from a chicken-and-egg problem: as long as informatics is not in the curriculum, there is Iittle incentive to educate teachers in the subject; as long as there are no teachers, there is Iittle incentive to introduce the subject.
To bring informatics education to the levei that their schools deserve, European countries will have to take both long-term and short-term initiatives:
• Universities, in particular through their informatics departments, must put in place comprehensive programs to train informatics teachers, able to teach digital literacy and informatics under the same intellectual standards as in mathematics, physics and other Sciences.
• The current chicken-and-egg situation is not an excuse for deferring the start of urgently needed efforts. Existing experiences conclusively show that it is possible to break the deadlock. For example, a recent New York Times article explains how IT companies such as Microsoft and Google, conscious of the need to improve the state of education, allow some of their most committed engineers and researchers in the US to pair up with high school teachers to teach computational thinking. In Russia, it is common for academics who graduated from the best high schools to go back to these schools, also on a volunteer basis, and help teachers introduce the concepts of modern informatics. Ali these efforts respect the principie that outsiders must always be paired with current high-school teachers.
(Excerpt of ' Report ofthe joint Informatics Europe & ACM Europe Working Group on Informatics Education April 2013')
According to the text, it is correct to say that:
Brazilian exports have tripled in the last ten years and now the country requires huge investments in port infrastructure. Investment projects in the coming years are likely to exceed R$19 billion.
The Brazilian infrastructure sector is gearing up to sup- port the strong growth of the country’s foreign trade. In the last 10 years exports have more than tripled, while imports have more than doubled. In order to handle the trade boom Brazilian ports – which handle 95% of the country’s trade by volume and 85% by value – have been receiving significant public and private investments.
At the same time, large-scale projects in transportation logistics (railroads, highways, waterways and airports) are now underway or will be starting in the short or medium term and will promote greater integration with the country’s ports system.
For its part the federal government has made the rules _______________ the ports sector more flexible _______________ the recent publication of Decree 6,620, which allows Brazilian and international private companies ________________ build and operate new public ports under concession. Ports Minister Pedro Brito said he hopes Brazilian ports will receive investments totaling R$19 billion through the coming years.
Investments are needed to expand and modernize Brazilian ports to handle the growth of foreign trade. From 1998 to 2008 Brazil’s total trade flow, counting imports and exports, jumped from US$108 billion to an estimated US$400 billion, of US$281 billion in 2007.
Brazil is also expanding the number of countries with which it trades. From January to September of 2008 Brazil exported to 224 countries and imported from 109. While Brazilian exports still include a strong element of commodities (petroleum, iron ore, soy, grains, coffee and sugar as well as newcomers such as ethanol and bio-diesel) they now also include high-value- added items such as airplanes, vehicles, engines, auto parts, processed meat and steel products.
The sentence:
“The Brazilian infrastructure sector is gearing up to support the strong growth of the country’s foreign trade.” can be correctly translated as:

Solar System’s Water is Older Than the Sun
Next time you’re swimming in the ocean, consider this: part of the water is older than the sun.
So concludes a team of scientists who ran computer models comparing the ratios of hydrogen isotopes over time. Taking into account new insights that the solar nebula had less ionizing radiation than previously thought, the models show that at least some of the water found in the ocean, as well as in comets, meteorites and on the moon, predate the sun’s birth.
The only other option, the scientists conclude, is that it formed in the cold, intersteller cloud from which the sun itself originated.
The discovery, reported in this week’s Science, stems from the insight of lead author Lauren Ilsedore Cleeves, a doctoral student at the University of Michigan, who realized that planetforming disks around young stars should be shielded from galactic rays by the strong solar winds, dramatically altering the chemistry occurring inside the disks, said Conel Alexander, with the Carnegie Institution of Washington.
“The finding... makes it quite hard for these regions in the disk to synthesize any new molecules. This was an ‘aha’ moment for us – without any new water creation the only place these ices could have come from was the chemically rich interstellar gas out of which the solar system formed originally,” Cleeves wrote in an email to Discovery News.
“It’s remarkable that these ices survived the entire process of stellar birth,” she added.
The finding has implications for the search for life beyond Earth, as water is believed to be necessary for life.
“If the sun’s formation was typical, interstellar ices – including water – are likely common ingredients present during the formation of all planetary systems, which puts a wonderful outlook on the possibility of other life in the universe,” Cleeves said.
In addition, it’s not just water that likely survived the solar system’s birth.
“The same must be true for the organic matter that we know is present in molecular cloud ices. So I think this strengthens the case that we have interstellar organic matter in meteorites and comets too,” Alexander wrote in an email to Discovery News.

Building a Practical College Degree for the New Economy
This is not a great time to be a recent college graduate.
Average student-loan debt is $29,400. The underemployment rate is 44 percent for graduates ages 22 to 27, meaning they are holding jobs that don’t require bachelor’s degrees. And the average age of financial independence for college graduate these days is 30.
Such statistics have given rise to the narrative that a college degree is no longer worth it, although volumes of economic studies on lifetime earnings prove otherwise. Even so, given the number of college graduates struggling to launch their careers, a wide gap has emerged between what the workforce needs in employees and what colleges are producing in graduates.
Part of the problem is that we have high expectations for the bachelor’s degree today. Thirty years ago, when fewer people required a higher education to get ahead in life, the bachelor’s degree was seen as a vehicle for broad learning. The training part came later by going to graduate school or getting a job where the new employer trained you.
Now we demand that skills training move in tandem with broad learning, and expect both to be completed in the four years of an undergraduate education. For too many students, however, the bachelor’s degree is not providing that dual experience – high-impact, in-classroom learning and out-of-theclassroom, experiential, and hands-on learning necessary for success in today’s economy.
Because of student loan debt, graduate or professional school is no longer an option for many recent college graduates. They’re searching for quick and cheap addon boot camps that give them what they’re missing. And a whole new set of providers are emerging outside of the traditional higher-education ecosystem to provide that lift.
Last year, General Assembly, which offers courses of a few hours to a few weeks in everything from digital marketing to web development, expanded to Washington, DC, where it is selling out of nearly all of its offerings. Its average student is in his mid-20s and just a few years out of college.
According to the text,
I. colleges are not producing in graduates what the workforce needs in employees.
II. nowadays, the bachelor’s degree is seen only as a vehicle for broad learning.
III. nearly 44% of graduates ages 22 to 27 hold jobs that require bachelor’s degree.
IV. colleges are expected to give students not only skills training, but also broad learning.
V. economic studies on lifetime earnings prove a college degree is no longer worth it.
The correct assumption(s) is(are)
Since the 1950’s, some athletes have been taking anabolic steroids to build muscle boost their athletic performance. Increasingly, other segments of the population also have been taking these compounds. An anual survey of drug abuse among adolescents showed a significant increase from 1998 to 1999 in steroid abuse among middle school students. During the same year, the percentage of 12th-graders who believed that taking these drugs causes “great risk” to health, declined from 68 percent to 62 percent.
Studies show that, over time, anabolic steroids can indeed take a heavy toll on a person’s health. The abuse of oral or injectable steroids is associated with higher risks for heart attacks and strokes, and the abuse of most oral steroids is associated with increased risk for liver problems. Steroid abusers who share needles or use non-sterile techniques when they inject steroids are at risk os contracting dangerous infections, such as HIV/AIDS, hepatites B and C, and bacterial endocarditis.
Anabolic steroid abuse can also cause undesirable body changes. These include breast development and genital shrinking in men, masculinization of the body in women, and acne and hair loss in both sexes.
[...] We hope that this compilation of scientific information on anabolic steroids will help the public recognize the risks of steroid abuse.
