Science Revision – What Is …..?

Science revision - what isAs a teacher I get increasingly frustrated with the amount of time my students waste searching for answers on the Internet. It’s hardly surprising, given the volume of information available. I liken it to putting a student in the middle of the largest library in the world, asking them a question, and then expecting them to come up with an answer in minutes from a suitable book.

Even Google, with all its massive search potential, is proving relatively ineffective at throwing up the needles in the haystack. In a recent copy of ‘Wired’ magazine the legendary Will.i.am talked about the need for information filters – we need to make searching smarter and less of a hit-or-miss process.

As a result of recent experiences I have decided to start putting together a range of simple videos to answer specific questions. I’m calling the video series ‘Science Revision – What Is …..?’, and the first video simply describes the difference between speed and velocity – how many times do students fail to understand this?

When asking questions on the internet students are invariably directed towards sites such as Wiki Answers – sometimes the responses given are appropriate, but at other times the responses are completely at the wrong level or utterly lame.

I am hoping that my short videos will answer many of the basic questions being asked by students – in fact, I’m hoping that they will be asking me questions and so giving me the opportunity to respond!

Science Revision Videos In The Top 30!

Revision Universe

Recently I’ve been looking at a website – Revision Universe - produced by Arnav Rawat.  Arnav really has been doing his homework, and he has put together an excellent list of revision resources, in subjects ranging from Biology and Chemistry through to History and Geography.  I know that my students often get overwhelmed by the sheer quantity of information available on the internet, and it’s really useful to be able to point them towards a site that has many quality resources.

Revision Universe also has an active blog, and there are some excellent articles from Arnav, and also some guest bloggers.  I particularly like the ‘Top 30 Educational Websites’ blog post.  Arnav has used his own judgement to put together a list of websites that he considers to be amongst the best available.  The ‘big hitters’ such as BBC Bitesize are not included in the list, but there are some well known ones such as S-Cool and Planet Science.

I’m really excited because one of my sites, Science Revision Videos (http://www.sciencerevisionvideo.com/) appears at number 17!  I developed this site a little while ago to showcase some of my biology and chemistry revision videos, and it’s proved to be very popular with students preparing for their exams.  I’ve also done some work for the site ‘Education Quizzes’ and I’m really pleased to see the site at number 11.

Arnav has done a great job with the educational website survey, and I do recommend that you have a look at it (and that’s not just because my site is listed!).  To visit the Revision Universe website just click on the image at the top of this blog or the link below.

Better Memory Retention With Spaced Learning

Spaced learning

Do your students find it difficult to take in and retain the facts that you’re teaching – I’ll bet they do!  Schools invest a lot of time and money encouraging their students to effectively revise.  As a teacher I find it frustrating that even though I may have flagged up a forthcoming test over and over again, I can guarantee that only a handful of my students will actually make any effort to revise.

Throughout my teaching career I have looked for better ways to encourage revision, and I’m still in search of that holy grail.  Recently I came across a reference to ‘spaced learning’ so I thought I should investigate in more detail and give it a try.

Blended Learning – Education In The Future?

Blended learningIn a recent issue of ‘Wired’ magazine, Daphne Koller (cofounder of the online-learning platform Coursera) expressed concern about the lack of educational capacity in many countries.  For example, it has been estimated that India will need 1,500 universities to accommodate its growing population.  A major stumbling block in any planning towards this goal is the fact that India is short of 300,000 faculty members.

Daphne Koller’s solution to the problem is a rapid expansion in online education.  In particular, she advocates the development of a blended approach, where students watch lectures at home and use the classroom for discussion.  It has been shown through research studies that blended learning is superior to purely face-to-face or online teaching.

Welcome To Online Science Teaching!

online science teaching

Hi, and welcome to my first post on this new blog.

The ‘About’ page gives you a brief outline of who I am, what I do, my family and my interests.  Suffice to say here, I am a science teacher and have been so for over 30 years (I stood in front of my first class in January 1983!).  So I have vast experience of teaching, and have been leading successful science departments since 1991. 
I decided to develop ‘Online Science Teaching’ following many months of hard work and late nights.  Let me give you the background……
