VIVAnews - Social networking sites like Facebook can help students to interact socially and academically, which ultimately improve learning outcomes. This conclusion was drawn from a study conducted by researchers from China and Hong Kong.
A group of researchers from the University of Science and Technology of China and City University of Hong Kong said their findings contradict the understanding of all this that the social networking site is a bully who divert the concentration of study.
Their findings, published in the International Journal of Networking and Visual Organizations, it was revealed that online social networking directly affect social learning and can positively affect academic learning.
"The pattern of social networks at up generally is in the form of the core mode and the periphery. Each individual has a close relationship with core friends and distant relations with many other friends, "said one researcher, as quoted by the media UPI, May 14, 2011.
To that end, social networking applications like Facebook offer an efficient platform for students social activities by expanding their network of friends and maintain intimate relationships.
In a survey conducted, it is known that Facebook allows students to relate familiar with the teachers and other students. They provide a platform to interact and share knowledge. Facebook also provides facilities for the students to join groups and discuss various topics, collaborate and use educational applications to manage learning activities.
"In the future, educational institutions may need to adopt active methods (but still controlled) like this to take advantage of social networking applications like Facebook for teaching and learning process,"said the researcher.
KOMPAS.com - The founders of startup, both the newly established "dream" and that began to develop his company, would require substantial capital to run and maintain what has been built. One way to get capital is to do the pitching to investors.
"Pitching is half exciting and nightmare," said Bernadus Sumartok, founder of Presentonomics.com when sharing his knowledge about the presentation in front of participants.
According to him, pitching could be a very cultivated because employers will meet the investors, but it would be a nightmare if his presentation was not optimal. Therefore Sumartok share how to build a simple slide presentation but can attract investor attention while pitching.
He divided the three major parts, namely: Mind of The Time (time division), Content is King (content presentation is king), and Visual (how visualization is very supportive presentation).
First, Mind in Time, or time sharing can be done by sorting what is not important, important, and most important. Then focus the discussion of the slide to the product, not the background or profile of the company. When explaining the product, better show than to say, because the audience is more interested in seeing the product directly compared heard the story. Ideally, within 15 minutes of presentation only consists of 12 to 20 slide presentation, then take advantage of the optimum.
Second, in terms of Content Is King. Ideal structure for startup when the pitching is discussing the contents starting from the introduction about the company and team, then continued by explaining the opportunities and competition in the industry, explain the business model, provides a question and answer, also gives the solution of problems that occurred in the vicinity of the user startup them. But the set of all essential information into simple, easily understood information audience. "Keep it simple slide," said Sumartok.
Third, the Visual. Sumartok suggested that a presentation using large images and high resolution, not the small picture and low resolution. "If it's necessary fill all the screen slides with images for clear," said Sumartok.
He added that the use of clip art in presentation means are not professional, so he suggested not to use clip art. Do not forget to provide enough white space on the image so there is space to enter text that reinforces the image. Then to type letters, on a slide, try to not more than two types of letters and for writing numbers should use Arial typeface because it is more clearly visible.
Two professional astronomers discover comet's orbit using the photos uploaded to the internet amateur observer.
By using the internet search engine Yahoo, Dustin Lang from Princeton University and David Hogg of the Max-Planck-Institut fur Astronomie in Germany discover unique photo comet 17P/Holmes 2476. Comet Holmes is the brightest object in the solar system and attract astronografer worldwide.
Lang and Hogg enter their photos into Astrometry.net who then recognize the image the sky and measure star pattern. Each photo has the information retrieval. When some photos taken together, the two astronomers can see the path the comet in the sky. Lang and Hogg then compare their orbit data with information from the Jet Propulsion Laboratory. The result, match.
Currently, astronomers are trying to trace the path of other comets, Comet Hyakatuke. They managed to get about 3,500 photos on Flickr alone Orion Nebula. These findings suggest that for science research can be done by digging the photos on the internet.
"Could make a survey of the sky with the pictures? answer is 'yes'," said Lang.
