With the recent announcement of 54,000 extra sixth form places in this years budget, it is more important than ever that teachers have the necessary aids to ensure all students get as much as possible from their education.
The main purpose of audiovisual technology is to improve communications, improve the way you want to impart your information and the way you deliver that information to your audience. This is particularly beneficial in the education sector as it helps tutors and lecturers get their information across to the students in the most effective way possible. Audiovisual technology doesn’t mean flashy and expensive and it’s not limited purely to those with a never ending budget, like all technology, packages, can be tailored to make sure you only buy what you need and to help make sure it really does prove productive to both you and your students, from projection equipment, to interactive white boards through to plasma screens.
The primary benefits of AV technology is all down to good communication, AV is there to support what you say, it doesn’t distract from what you’re saying. The easier and more efficiently you impart your lesson, the easier and more efficiently your students can learn. This of course makes the whole teaching experience more effective and time productive, for example, if your lecture notes are displayed on a clear screen or overhead projector, your students may find it easier to take notes and you don’t have to keep stopping or repeating yourself.
Universities have been investing in AV technology for a number of years. A lecturer, lecturing to a room of 150 students cant just be done from a lap top, you need good quality audio visual equipment to enhance both the visual and audio impact. If it is made interactive, students are more likely to take it on board and engage in the lesson that much more. So it’s really a case of using audiovisual to assist the lecturer and for the students to enjoy it and learn more.
It’s not just universities and colleges that can benefit from audiovisual technology though, one of the key benefits of AV technology in primary and secondary schools would be interactive white boards. Over the last two to three years, the Government has recognised that AV technology is raising the standard of the classroom in terms of the equipment which can in turn, help the children learn more.
Technology is a huge part of children’s lives, they use it everyday from texting and using mobile phones to social networking sites, if they see this same level of technology in their classroom, studies show they are more likely to engage in their lesson.
Interactive style voting systems are becoming more and more popular and this is now being integrated into the classroom. It’s all down to engaging the student, a question can be put on a board and the pupils have an interactive voting system, the pupils can even give information. Traditionally, if a teacher asks a question to a class full of students, half may raise their hand, but only one can answer and the teacher has no way of knowing whether every student knew that answer or whether the student who was picked was the only one. An interactive voting system ensures every student has the chance to answer and even better, the teacher can see at a glance what percentage of the class knew the answer and this can help them gage whether or not they can move onto the next topic or whether they may need to spend some more time on it. This also means that no student is overlooked and the quieter students who are normally too shy to volunteer an answer can be equally assed by the teacher.
This is a much more effective than waiting for an end of week or end of term test, by the time the teacher gets the results it may be too late to go back to the topic and ensure all the pupils are up the required standard.

Help answer the question about technology
What technology or electronics could you do without in a recession?Since economic times are getting more difficult, what electronics or technology would you eliminate to save money? For example, cutting back on cellphone use, cable service, satellite radio, video games, internet usage, etc. Give a brief reason why you picked that item.
Technology is not bad.
It's how we use it and whether we consider all the consequences before we put it in place. We have not done that in the past. We can't do things that way anymore.
Technology is what we will use to solve the problems that our misuse of it has brought about.
At the same time, we have to realize that sometimes simple technology is the answer. For example, here's a company doing something to save fuel for ocean freighters. It is really low tech, and it works.
http://www.skysails.info/index.php?id=20&L=1
and an American company doing the same thing.
http://www.kiteship.com/
These are parasails for ships. The cost of retrofitting a ship is dirt cheap. About the cost of leasing a large cape size bulk carrier ship for 2 days.
http://www.pluginpartners.org/
Plug in Partners is an advocacy group for plug in hybrid cars. This is what we need now. The average American driver would get 100mpg overall, and could charge the battery overnight, during off peak electricity demand, for $1.
That would get the average commuter back and forth to work, using no gasoline. You would only use gasoline on longer trips.
Here's a new book that demonstrates what we can do to save our planet while benefitting economically from the positive changes.

"Krupp and Horn have turned the doom and gloom of global warming on its head. Earth: The Sequel makes it crystal clear that we can build a low-carbon economy while unleashing American entrepreneurs to save the planet, putting optimism back into the environmental story."

article on creative financing for solar, including what Berkeley is doing
http://www.greentechmedia.com/articles/solar-temblor-9-big-trends-page10.html
It takes the sting out of the up front cost of installing solar. This is also happening on a corporate level, with companies like Morgan Stanley setting up financing and power purchase agreements for corporations and other large businesses to install solar panels.
Power purchase agreements are how power companies in California, Nevada and Arizona are contracting for solar thermal power plants in the southwest. These PPAs are a very positive move in the right direction.
Here's what's happening on the cutting edge of thin film solar cells and panels
"Nanosolar’s founder and chief executive, Martin Roscheisen, claims to be the first solar panel manufacturer to be able to profitably sell solar panels for less than $1 a watt. That is the price at which solar energy becomes less expensive than coal."
“With a $1-per-watt panel,” he said, “it is possible to build $2-per-watt systems.”
"According to the Energy Department, building a new coal plant costs about $2.1 a watt, plus the cost of fuel and emissions, he said."

This article shows how we could have a 69% solar electric grid by 2050, building solar power plants in the southwest.
Scientific American A Solar Grand Plan
http://www.sciam.com/article.cfm?id=a-solar-grand-plan
I don't agree with all the specifics of this proposal, but it is generally a good idea, even if we only do half or a third of what they are recommending.
It's becoming apparent that solar thermal plants are a better idea than the concentrating solar photovoltaic plants that they are emphasizing. And molten salt for storing thermal energy to generate electricity at night from solar plants is looking like the better idea. They propose caverns filled with compressed air. Molten salt only loses about 1% of it's heat over a 24 hour period, and doesn't involve digging all those caverns.
"The same acre can produce 10 times as much energy from wind as it can from corn ethanol, 180,000 miles per acre per year. But both corn ethanol and wind power pale in comparison with solar photovoltaic, which can produce more than 2 million miles worth of transport per acre per year." http://www.ecogeek.org/content/view/1454/70/
"Solar thermal power plants such as Ausra's generate electricity by driving steam turbines with sunshine. Ausra's solar concentrators boil water with focused sunlight, and produce electricity at prices directly competitive with gas- and coal-fired electric power."
"Solar thermal power plants can store energy during daylight hours and generate power when it's needed. Ausra's power plants collect the sun's energy as heat; Ausra is developing thermal energy storage systems which can store enough heat to run the power plant for up to 20 hours during dark or cloudy periods."
" All of America's needs for electric power – the entire US grid, night and day – can be generated with Ausra's current technology using a square parcel of land 92 miles on a side. For comparison, this is less than 1% of America's deserts, less land than currently in use in the U.S. for coal mines."
"In recent months, PG&E has signed deals for more than a gigawatt of electricity — enough to light more than 750,000 homes — with solar power plant developers. Such power purchase agreements can take more than a year to hammer out and the permitting and construction of a solar power station can take another three to five years."
"The solar thermal industry is in its infancy but utilities like PG&E (PCG), Southern California Edison (EIX) and San Diego Gas & Electric (SRE) have signed several contracts for solar power plants and negotiations for gigawatts more of solar electricity are ongoing."

Biomass to methane power also has big potential.
Sewage treatment plants, landfills, farms etc can all use anaerobic digesters to gather methane for power. This methane would eventually develop as things decompose and become greenhouse gas adding to global warming. This kills two birds with one stone. Check out what Environmental Power Corp is doing in this area.
Wind power
"In the US, the American Wind Energy Association forecasts that installed capacity could grow from 11,603 MW today to around 100,000 MW by 2020. In Canada, Emerging Energy Research predicts that installed wind capacity will expand from around 1,500 MW today to around 14,000 MW by 2015."
{from an article at altenergystocks.com by Charles Morand}
We now have a fledgling bioplastics industry which can make plastics from plant material like corn or non food plants like switchgrass. We now use 5-10% of our oil to make plastics, which create huge environmental problems, especially in the oceans.
Most plastic floats near the sea surface where some is mistaken for food by birds and fishes. Plastics are carried by currents and can circulate continually in the open sea. Broken, degraded plastic pieces outweigh surface zooplankton in the central North Pacific by a factor of 6-1. That means six pounds of plastic for every single pound of zooplankton."

Oh, come on, it's just GOTTA be the transporter.
Very glad to see your message making it across traditional borders that surround the academy.
And nicely done, too!
Good one Dave, what you say starting at 10 minutes was critical I think.
well if you think about it, technology makes experiments easy to be tested. You don't really want to wait all day to prove that your hypotheses was right, so technology really helps science. If your trying to prove something or test something, technology makes you life way easier. They're different because technology deals with making life easier and then there's the technical stuff about machinery and ya da ya da. Technology deals with more broader scale than science, it's like more hands on. Technology is cool too. While science is much cooler, Science is been around than technology. But anyway, science deals with everything, from testing an experiment to finding a cure for a disease. Science deals with explanations and experiments.
Establishing budget must be the first step in my opinion. Do you want proprietary hardware and kit in terms of that technology cul de sac that often occurs. What are the requirements in terms of users, is it that boardroom to boardroom type of scenario or is it more about groups / teams not just the management ? To get the best value from the type of activity "video conferencing" you're looking at – think along the lines of – what kit is required (hardware, bandwidth, quality, user interface) what financial foot print from an ongoing point of view. Desktop to boardroom – multipoint video and browser independence for future proofing your solution will address the flexibility aspect of "all" of your company and perhaps everyone your company deals with. The legacy issue is one of the biggest problems companies find themselves in.. who supports your hardware… and how much will that cost?

Oh, there was that bit in the bible where Jesus turned dihydrogen monoxide into ethyl alcohol… or the part where he walked on surface tension… oh wait… its just a story…………….. P.S. please learn how to use grammar correctly.
You are correct: it is black light (ultraviolet light).

I see big advancements in material sciences nanotechnology and the usual advancements in computers for the next 30 years or so: lighter planes, better medical treatments, cheaper stronger structures, faster and faster computer, etc…
One hundred years is a long ways off. I'm not sure but I think the whole doubling processing speeds every1.5 years will breakdown by then and we will be turning to quantum computers that uses the states of subatomic particles instead of binary. Moon bases, American flag on Mars, trans Atlantic subway, space vacations for the wealthy (not super wealthy), more renewable energy power sources, no ice caps, and a Starbucks in everyones hourse =)
It's worse, some people cannot even spell "the" online without screwing up.
Thanks to my trusty companion, Hot Rod (an MX-400 Logitech mouse)
I never misspell when I post because of the auto-spellcheck and correction click and I am wise enough to know what word to use.
Poor education and texting is in my mind, the evil source of all this illiteracy. The phone companies should boost the memory capacity of their phones for typing in coherent english or parents should lecture their kids that this is not how you should write a book report and take their phones off them for a month or two.
On the other hand,
New words like "smart phone" "quantum computing" and "fanboy" are entering our language (I do not consider internet gibberish to even qualify for a dictionary EVER)
Communication is faster than ever, you can make friends who live in another country and tell them what hobbies you are into and they send a response in seconds.
I'm holding out hope for voice recognition software to replace the keyboard so that the computer types what you dictate in correct punctuation and spelling with a touch screen manual override in case you are sick with laryngitis or just don't feel like talking to a machine.
The english language is at a crossroads and it is up to us to decide if keeping it "pure" or letting slang and pop culture interact with it is for the best.
