Spiro and Georgina Liacos: enhancing student skulls, oops, skills with outstanding video and print resources.

Hi everyone,

It’s fairly clear, if you browse our website, that we produce educational science videos and activity sheets which are designed to make learning easier for all students and which help teachers teach more easily and more effectively. The Shedding Light videos have been seen by literally millions of students and teachers around the world.

We’d prefer to let our videos and student activity sheets speak for themselves, but in case you’re wondering who we are, let me tell you who we are.

My name is Spiro Liacos and I’ve been passionately teaching Science, Physics, and PE for more than 30 years. I’ve presented at Physics teachers’ conferences and at Science teachers’ conferences, I’ve had articles published in LabTalk (the Science Teachers’ Association of Victoria’s magazine), in Science Education News (the journal of the Science Teachers’ Association of NSW) and in Teaching Science (the journal of the Australian Science Teachers Association). I produced a worksheet which NASA (yes, the NASA) distributed around the world to its various affiliate educational programs. (See the Space Shuttle activity on the Investigating Motion page).

Together with my wife Georgina, a qualified Primary School teacher who has a keen interest in film and photography, we formed LEM in 2011 after we produced our first video Shedding Light on Colour.

Since then, we have produced 9 Shedding Light series composed of 54 videos, which themselves are broken up into hundreds of sections. This allows teachers to tailor the way they use the videos. For example, the Heat Transfer video is broken up into individual sections that cover conduction, convection, and radiation. If a class gets through only, say, two sections in a lesson, they can use the third section in the next lesson! We’re making more series, because my own students love them, as do teachers and students around the world!

I still work part time in a secondary school in Melbourne, Victoria, so I test all the videos we produce with actual classes to make sure that the content is clear and interesting and that the accompanying activity sheets effectively guide students through their learning.

I am absolutely thrilled with how well my students respond to the videos. Sure kids can learn by reading textbooks and copying notes from a PowerPoint, but nothing beats watching a video to learn something, especially when the learning activities that follow are tailor-made to the video.

For example, Shedding Light on Atoms Episode 7: Covalent Bonding and Shedding Light on Atoms Episode 8: Ionic Bonding, cover the two types of bonding in clear detail using real-life footage and outstanding, no-nonsense animations. I remember trying to teach my students using the old ways and finding that many students struggled. When I used these videos and their accompanying worksheets to teach bonding, their test scores were through the roof compared with previous cohorts of students!

And, I didn’t have to work hard to explain stuff over and over! The videos did it all!

Teaching is a really tough job, so let us help you teach the topics of Light, Atoms (Chemistry), Energy, Heat, the Sun and Earth (Climate Science), Motion, Electricity, and Acids and Bases and let your students benefit both from your experience, and from ours!

    Most of our videos are also available on SAFARI Montage. Just log in and do a quick search. (we can’t provide links because SAFARI Montage uses a different web address for every school.)

    Don’t have these services?

    Watch the programs on Vimeo.

    Just join Vimeo (or sign in if you have already joined) and you’ll be watching in no time!!

    stream on any device…

    Schools may like to join Vimeo with a communal email address. Individual teachers can then sign in and bring the power of the Shedding Light programs to their classrooms!!

    Students (with their parents) may prefer to rent a series to give themselves a fantastic boost in the topics that each series covers.
