So many great ideas, so little time…
November 30th, 2008

This evening I checked through my feedreader, I use NetNewsWire. As I scan through the blog posts and the various news feeds I select those items that I would like to explore further. I prefer to read the full post in a browser. Clicking on the feed title opens each post in a browser with a new tab. I then quit NetNewsWire and begin reading the relevant posts in Firefox or Safari for example.

Tonight I earmarked about 50 items. There is a variety of content. Book reviews, inspiration, video, links, resources, technical tips, sites I feel that may benefit my colleagues and so on.

Fifty great ideas. Tap twice to begin, tap once to stop.

I will read through a number of the items this evening, comment here and there, and continue with the rest during the week. I may even add a few to Diigo (and Delicious by default).

At other times I may note 60, 70, 80 or more posts or items to read. It is overwhelming at times. There is so much great stuff out there. So many great ideas, so little time…

Google Maps: World’s largest liquid paper correction?
November 23rd, 2008

This morning I posted about Google Maps and some of the interesting discoveries made by users of the tool in the past. I just made one of my own. I was exploring the town of Pasir Ris in Singapore and discovered a strange white blotch near the intersection of Pasir Ris Drive 1 and Pasir Ris Drive 4.

What is this?

What can it be? A massive liquid paper spill? A horrendous bird dropping?

Google Earth discoveries
November 23rd, 2008

Google Earth and its browser based cousin Google Maps fascinate. This morning I read that a possible meteorite crater has been discovered in western New South Wales. The report in the Sydney Morning Herald tells the story of opal miner Mike Fry and how he spotted the crater via Google Earth. Mr Fry had been using Google Earth to explore terrain for possible opal mining sites. The site requires further geological investigation to confirm it is the result of an meteorite impact. The western rim of the site is visible. The eastern rim has been significantly eroded and is no longer visible.

Earlier this year another potential impact crater was discovered in Western Australia by Dr Arthur Hickman, a government geologist with the Geological Survey of Western Australia.

If you are interested in similar discoveries and meteorite craters around the globe this Google Earth Hacks site, Craters [scroll down], and this Google Maps site, Meteor Craters may interest you.

It fascinates that both of these geological ‘discoveries’ were made whilst seated in front of a computer display.

Have you ever made a ‘discovery’ while exploring Google Earth or Google Maps. Some time back I was exploring some of the towns where my wife and I had lived while we were living in Singapore. To my surprise I ‘discovered’ that a group of trees that were located in a park that was adjacent to our estate spelt out the name of the town, Pasir Ris. We had walked through and around the park many times yet we never realised that the trees had been so planted.

In the classroom I like to use Google Earth to support the teaching of history. It is particularly useful when teaching students the history of the Persian Wars. Sites for battles such as Marathon, Salamis, Thermopylae and Artemisium are all accessible. Of course the terrain and coastlines have altered to some extent yet the maps provide an invaluable viusal for the students and it makes the events all the more tangible.

Both the Battle of Thermopylae and the naval battle of Artemisium were fought in this region.

The Battle of Salamis was fought in the narrows between the island of Salamis and the coastline of ancient Attica

So, have you made any “discoveries” using Google Earth? What do you think are some of the more interesting locations visible via Google Earth? How do you use Google Earth in the classroom?

Teach the past or teach the future?
November 17th, 2008

Presently watching a documentary on television entitled “Where’s My Robot?“. Will not go into too much detail. Essentially the presenter went on a quest around the world looking for the robot that he had wanted as a child. Robots of varying capabilities in laboratories around the world were investigated. Researchers still have a long way to go. I wonder if this area of research is useful. Robots that can function in hazardous environments will be practical. Yet I wonder, are we spending money in the right places?

Given the challenges that the human race face with global climate change, for example, I wonder if I should change tack and begin teaching students about the past, the present and also the future. As a child I was so looking forward to the future. Well, the future has arrived and it has not matched my youthful expectations.

Growing up I had an interest in astronomy, space exploration and the future. I enjoyed reading books that provided glimpses into the future. When I turned 10 my father gave me a book entitled “Our World In Space and Time“. It was published in 1959. I have scanned a couple of images from the book in order to illustrate my thoughts. The book was essentially an overview of the the planet earth, its place in the universe and mankind. It was anglo-centric and written with an “imperial” view of the globe and its residents.

The overall impression it gave of the future was optimistic. There was no real hint that the resources of the planet were finite. In fact one of the chapters was entitled, “Forests that cover a quarter of the earth”. The chapter mentions that although there is a timber shortage in Europe and that “western Europe still needs more timber than it can easily come by.” Timber could be easily sourced from elsewhere. The image below faced the chapter. As you can see it shows forest clearing. It is depicted as a manly and exciting adventure.

Cut them down boys. Plenty more elsewhere.

The United Nations reports that about half of the world’s forests had disappeared and that most of that loss occurred during the three decades leading up to 1997. Afforestation projects are reversing the trends in some areas but it is not enough. ”Deforestation, mainly due to conversion of forests to agricultural land, continues at an alarmingly high rate – some 13 million hectares per year.” [Global Forest Resources Assessment 2005].

I live in Australia. It has the world’s fifth highest ecological footprint in the world. We are one of the greediest nations on the planet per capita. Shame. We need to do something.

The same book provided an optimistic view of space exploration as well. That dream has certainly not come to pass. The book and myself envisioned the 21st century with significant orbiting space stations, regular manned trips to the moon, bases on the moon, explorers on Mars and manned journeys making their way to the outer reaches of the solar system. Admittedly the text book was published in 1959 and Yuri Gagarin had not made the first manned space flight. But the vision seemed so possible.

The world in 2000

In 1973 I bought a book entitled Challenge of the Stars. It was published in 1972. It set out a series of predictions regarding the exploration of space by mankind. One of them was the establishment of a base on the moon by the 1990s. The illustration below sets out their ideas for life on the moon about 1990. It all seemed so easy back in 1973.

Moonbase 1990

I watched Stanley Kubrick’s 2001 A Space Odyssey as well during the evening. It presented a magnificent view of space travel in 2001 with regular space flights by Pan American Airways, massive space stations (that resembled a five-star hotel within), a moon shuttle, large bases on the moon, inter-planetary travel and so on. It was a grand vision. In 1968 it all seemed to be within our grasp. It seemed that all of that could be achieved. [I am not advocating that the human race attempt to achieve these goals now. More important matters are pressing.]

What has happened? The Clavius moon base illustrated in 2001 A Space Odyssey could not even be built on the planet earth in 2008 let alone on the moon. This planet is too busy building massive shopping centres while others starve. Nothing shits me more than seeing news reports about food eating contests, world record hot-dog consumption attempts and the like. I think that is obscene, particularly when one is likely to see images of starving or poverty stricken children during the same news bulletin. What is wrong with the human race?

In recent weeks wealthy nations around the world have raised nearly $USD5,000 billion to fight the global financial crisis. I am not an economist but one wonders if the planet’s economy was better managed in the first place surely that $USD5,000 billion could have been put to use preventing some of the woes that face us in the 21st century? Where did that money come from?

Governments around the world are tightening their budgets and going into deficit as well. Will they also reduce their proposed budget allocations originally designed to combat global climate change? Where do all of those promises stand now?

Imagine if governments no longer had to include the military in their budgets? The money could be spent on cleaning up the planet and feeding people. Of course, if that was to happen there would be military coups on every continent. The military would not allow it to happen.

There are times when I feel guilty. I have this laptop, a digital camera, a TV, etc. What is my ecological footprint?

The optimistic vision of the 21st century that I grew up with as a child is not coming to pass. The 21st century is beset with famine, poverty, climate change and a growing chasm between the rich and the poor.

I feel that we should be teaching students a range of values where materialism is not paramount. Community, resilience, sharing and giving. Positive values for the future. [I hope I do not sound like a politician. It sounds like something Kevin Rudd would say.] Yes, we share by example in our schools yet I feel that a more substantial slice of the curriculum should be devoted to teaching our students and ourselves how to really live on this planet.

It is the only planet that we have and given that by 2050 mankind will require the resources of 2 or 3 similar planets to satisfy the needs of the human race one wonders what will be left for the children of our current crop of students? Presently it is taking the planet 1.2 years to regenerate what is taken by mankind in a single year.

We need a new subject. It’s focus should be on the future. Not sure what to name the subject. But we need it. Maths, English, Music, History, Art, Science, Geography, and… Life.

Addedndum. I was exploring the ABC web site and discovered this interesting clip on their new Fora site. I am yet to watch all of it however it fits in with my thoughts here to some extent. The video consists of a debate between Harvard historian Niall Ferguson and futurist Peter Schwartz about which of the two disciplines is the better: Historian or Futurist?

 

Thunderstorm across the Illawarra
November 14th, 2008

As I type the last few drops of rain are falling on the verandah. A storm just crossed the Illawarra coast. There was quite a great deal of lightning. I managed to capture one bolt. I left the shutter open for 10 seconds and narrowed the aperture.

Not too high tech or professional but it worked, at least for the photograph above. I have played around with the photography of lightning in the past. I am quite happy with the photograph below. After that shot was taken I went inside. The storm was too close for comfort.

Mathematics teachers have it too easy
November 14th, 2008

Each day I share a ride with three other colleagues on the way to school. We all live near each other. We take turns to drive to school, week on week. We estimate that our travel costs are about $7.00 to $8.00 a week. Car pooling is a good idea. We travel against the flow of the traffic as well. Every day we see all these commuters driving into town, occasionally banked up for kilometres. The last part of the drive is rather scenic as we pass by dairy farms.

Well, on the way home one of my car pool buddies marked the final examinations for his Year Nine Mathematics class. He has 28 students. The exam finished at 3.15PM and he began marking straight away as he waited for one of our colleagues to complete bus supervision duty. He continued marking as we made our way home in the car. It was my turn to drive this week. He had completed his marking before we reached his home. The drive is about 20 minutes. There were multiple choice questions and equations to mark. He finished them all. The entire class. He can relax this weekend.

I teach the same class. History. They did their final examination today as well. I will have essays and extended responses to mark. It will take up most of the next few evenings. I teach two other similar Year Nine classes. All up 87 students. That is 87 essays, and 261 extended responses. Then there is Year Eight History. More essays and extended responses. They did their yearly examination as well. The marking is part of the job. I accept that. That is fine.

I guess I sometimes wish I was a Mathematics teacher at marking time. Mathematics teachers have it too easy.

Think I will make my way to the fridge and grab a beer.

Remembrance Day
November 11th, 2008


Commonwealth War Graves, Kranji, Singapore

Today is Remembrance Day. Today many people around the world commemorated the sacrifices of soldiers and also civilians in times of war. The day marks the end of the First World War on the 11th November, 1918.


Commonwealth War Graves, Kanchanaburi, Thailand

The students at our school marked the day with a service at 11.00AM. It was at this time on the 11th November, 1918 when hostilities ceased. Myself and three students also attended a service at the Albion RSL Sub Branch Memorial Club. The service was led by Harry Spicer OAM.

The aim is not to glorify war. Simply to remember.

The end of the school year beckons…

Preparing for exams
[Source: Wikipedia: Factory farming]

This may seem premature yet the end of the school year is fast approaching. The last day of school is the 18th December. More than five weeks away. The students will probably complete their academic school year during the previous week. The final week is taken up with presentations, parent interviews and professional development.

This week our students in Years 7 to 10 are undertaking their final examinations. The weeks leading up to these examinations involved catch-up lessons, revision, summary notes, practice tests, and similar. It has been rather frenetic. This time of year always seems so far away yet it creeps up on you and the students are sitting for the final examinations.

The driven students seek additional trial tests, opportunities for revision and those elusive hints. Other students do not seem to have a worry in the world. Some of my students went on a holiday during the week leading up to the exams. How is that for a carefree, laissez-faire attitude? Have you witnessed that in your teaching career?

So, examinations for years 7 to 10. Only the students in Year 10 are sitting for an external examination. The NSW School Certificate. The majority of the Year 10 students were keen. Yet, a number of the students know that they will be returning to Year 11 regardless of the result that they achieve in the School Certificate. There is something fundamentally awry with that. What do you think? I suspect that the School Certificate will be no longer in the not too distant future.

After this week the teachers will be marking exams, writing reports and meeting deadlines. The students are aware that although the school year is not yet over the assessment programme has been completed. I see some of you have a wry smile on your face. Some educators have labelled this time of year “the silly season”. That does not sound too good. I know a number of the parents would not be too impressed to hear that. Particularly fee paying parents.

During this time of the year the teachers have to be really on their game. This is when you unearth the interesting lessons and the intriguing projects. That is awry as well. We should be engaging in the really creative and interesting strategies during the course of the year but the examinations act like a finishing line that we must cross at all costs. The examinations sometimes force us to adopt factory farming strategies to force feed the students. There are students and parents that almost demand it. “Fill up my brain with factual fodder so that I can get an A“.

Examinations. I have mixed emotions about them. Certainly professionals and students training to be in a role in which the lives and safety of individuals are at stake should pass through a testing regime of some form. Yet, students in an academic environment where progression from one year to the next is a given should not have to waste their time with a period of examinations not unlike those undertaken by my parents back in 1932. Surely their competencies and skills can be measured by other assessment methods.

I confessed I have mixed emotions about examinations. Quizzes and tests seemingly have their place in some contexts. A number of the students actually enjoy them. Others do not. Some students enjoy the competition. Others do not.

How do you feel about examinations? Does your school also experience a period during the academic year when all assessment is complete yet the students still have a few weeks of school to attend? Are your students assessed right up until the last day of the school year? If so when do you create your reports, etc?

What shall I be undertaking with my students during November and December? I hope to explore a few technologies with a number of the classes. Of course there are the students who take advantage of the situation and ‘play the game’. Who can blame them? Good luck to them. I shall endeavour to be one step ahead and make sure that they derive value during these last few weeks of the year. We have considerable latitude in what and how we teach during these weeks.

If you were I how would you be teaching the students during the coming weeks? 

Multiple choice test madness
November 11th, 2008

Our homestay student just arrived home from university. She completed a final examination in biology today. The examination lasted for 2 hours.

The examination consisted of 120 multiple choice questions. Each question had five options from which to choose. Not four options, five!

Think about it. On average each question had to be dealt with in 60 seconds. Each option needs to be considered in say 12 seconds. Less, when you think about it further.

That is madness. That is an abuse of the multiple choice question format. The lecturer is simply lazy in my estimation. Easy to mark, true. Fair on the students, not true.

120 multiple choice questions in 120 minutes for an examination that covered an entire annual course.

Which university? The University of Wollongong. Which faculty? Science.

That is not an education.

Pompeii and Herculaneum ~ resources and links
November 10th, 2008

Students undertaking the 2 Unit Ancient History course in the New South Wales Higher School Certificate are required to complete a compulsory study of Pompeii and Herculaneum. When they attempt the relevant section in the final examination they need to answer three questions as follows:

Question 1, which usually consists of several parts, requires the students to extract relevant information from some or all of the historical sources included with the question.
Question 2 requires the students to employ historical sources and apply their own knowledge to reconstruct aspects of life in Pompeii and Herculaneum.
Question 3 requires the students to refer to sources and apply their own knowledge to issues of investigating, reconstructing and preserving the past and related ethical issues.

My students are presently researching for a presentation on the life and society of the people of Pompeii and Herculaneum. They are permitted to use technology to faciliate their presentation. Each student has to collect a range of historical sources to augment their presentation. I hope to utilise a wiki or web site to collate all of their material.

I have updated a dedicated web site of links to research, resources and photographs of Pompeii and Herculaneum.

Links include the Soprintendenza archeologica di Pompei, The Forum at Pompeii, Mazois’ famous sketches of Pompeii, CyArk’s multimedia exploration of Pompeii, the excellent QuicktimeVR panormas created by Francesca Tronchin and Diego Bonilla, an extensive gallery of images at the University of Buffalo and John Hauser’s pictures of Pompeii. I have also added a set of links to relevant galleries on Flickr.

Sootie as a kitten
November 9th, 2008

Early one morning Sootie discovered himself in the mirror. He attacked himself for some time. This was a couple of years ago when he was a kitten.

 

This post was inspired by Maru, a Scottish fold cat that lives in Japan. My wife and I discovered Maru via Boing Boing. Maru has a blog and a YouTube page.

Sri Venkateswara Temple
November 3rd, 2008

Last weekend Shao Ping and I took our Taiwanese homestay student Jenny and her boyfriend Ho Yen for a drive. We went north across Sea Cliff Bridge via the Grand Pacific Drive and up to Bald Hill to take in the view of the Pacific Ocean. We then paid a visit to Sri Venkateswara Temple which is located south of Helensburgh.

It is a beautiful temple. I shall be posting more photographs over time. The temple’s history goes back to 1978. The temple’s web site has a gallery of excellent photographs. We also had our lunch at the temple. We ate some prata with a rather nice curry plus some masala tea. Very nice indeed. I took a few photographs.
