Logical fallacy

I was sent an email containing the following statements. Politics aside, I like to comment on the logical fallacy committed by the sender.

Statement:

If any other of our presidents had doubled the National Debt, which had taken more than two centuries to accumulate, in one year, would You have Approved?

If any other of our presidents had then proposed to Double the debt again within 10 years, would you have approved?

Fallacy: Judging an action which asking the cause of the action. What else can Obama do when he inherited a situation that bad?

Statement:

If any other of our presidents had criticized a State Law that he admitted he never even read, would you think that he is just an ignorant hot Head?

Fallacy: How does one know if another person has or has not read something? "that he admitted he never even read" - What is the context when this admission was made?

Statement:

If any other of our presidents had pronounced the Marine Corps as if it were the Marine Corpse, would you think him an Idiot?

Fallacy: Diversion. What has the pronunciation have to do with an argument?

Statement:

If any other of our presidents had put 87,000 workers out of work by arbitrarily placing a moratorium on offshore oil drilling on companies that have one of the best safety records of any industry because one foreign company had an accident, would you have agreed?

Fallacy: Almost every policy will have winners and losers.

Statement:

If any other of our presidents had used a forged document as the basis of the moratorium that would render 87000 American workers unemployed,
would you support him?

Fallacy: "forged document" - proof needed. BTW, was it not that USA invaded Iraq based on false premise - the Iraq has weapon of mass destruction?

Statement:

If any other of our presidents had been the first President to need a teleprompter installed to be able to get through a press conference, would you have laughed and said this is more proof of how inept he is on his own and is really controlled by smarter men behind the scenes?

Fallacy: Good point. Just watch the following video.

A talk on TED:

Free energy

A basic principle in Physics, at least in the realm of our everyday size, energy is conserved. That means that perpetual machine is an impossibility. However, here are two videos on youTube which claims to produce free energy with over millions of views.



Power is not just voltage. Power is voltage times current. By increasing the number of turns in the rotor, we can get a higher induced e.m.f, ie voltage. But once a load is applied, there will be a current and the current will generate a force to oppose the motion and hence stopping the rotor. So far, no one has just demonstrably show a perpetual machine, not to mention extracting additional energy out of the machine.

Can you erase data on your hard drive using a magnet?

Neodymium Magnets are strong magnets. In an experiment by one of such magnets' seller, we would expect a positive result. Well, K & J Magnetics did an experiment trying to erase the data of a harddisk.

With the hard drive running, we were not able to disrupt the contents of the drive at all. 100% of the files were completely intact and accurate. This result completely surprised us!

My own explanation is that the metal case of the harddisk, being magnetic, acts as a magnetic Faraday cage protecting the media inside the harddisk.

Donald Bell at CNet wrote

More-concrete specs are now taking shape, including an ambitiously low power rating of 1 watt per hour (compared with the 5 watts per hour required by the OLPC laptop) [my emphasis]

"Watt" is a power unit. It is defined as 1 Joule per second. Watt per hour means nothing here. From the context, the new XO-3 tablet will consume only 1 watt or 3600J per hour.

As a senior editor at CNET, Bell should have at least an elementary knowledge of science to get the units right.

Food to life as computer to education

What would be your response when you received a notice from school something similar to the following email?

From: Margaret Bennett
Date: Friday 22 August 2009 3.40pm
To: David Thorne
Subject: computer room

Hello David
I tried to call you but your phone is off. Just letting you know that Seb bought a flash drive to school yesterday and copied a game onto the school computers which is against the school rules and he has been banned from using the computer room for the rest of the term.
Sincerely, Margaret

Here are some responses from the parent, taken out of context and order. You can read the actual transcript here.

I was not aware that my offspring taking software to school was in breach of school rules. Although the game is strategic and public domain, not to mention that it was I who copied and gave it to him, I agree that banning him from access to the computers at school is an appropriate punishment. Especially considering his enthusiasm for the subject.
Also, though physical discipline is not longer administered in the public school system, it would probably be appropriate in this instance if nobody is watching. I know from experience that he can take a punch.
[in next email exchange]
Also, if you happen to see Seb eating anything over the next few weeks, please remove the food from him immediately. He forgot to feed his turtle last week and I feel a month without food will help him understand both the importance of being a responsible pet owner and the effects of malnutrition.

Did the teacher get the message from the parent? Apparent yes,... but...

I have no idea what your point is. I will speak to the principal about the ban but you have to understand that only government approved software is allowed on the computers and Seb knew this rule.
Margaret

Here is the reply:

Subject: Re: Re: Re: Re: Re: Re: Re: computer room

Dear Maggie,
I understand the need for conformity. Without a concise set of rules to follow we would probably all have to resort to common sense. Discipline is the key to conformity and it is important that we learn not to question authority at an early age.
Just this week I found a Sue Townsend novel in Seb's bag that I do not believe is on the school approved reading list. Do not concern yourself about it making its way to the school yard though as we attended a community book burning last night. Although one lady tried to ruin the atmosphere with comments regarding Mayan codices and the Alexandrian Libraries, I mentioned to the High Magus that I had overheard her discussing spells to turn the village cow's milk sour and the mob took care of the rest.
Regards, David.

And finally:

David,
I have spoken to the principal and in this instance we will lift the ban.

Since education has become a public good and most schools are funded from the public purse, the salary of the teachers have fallen to the point that any university entrant applicant would be considered irrational to apply for a place in the education faculty if this is not the last choice. How can we continue our prosperity with the coming under performing citizens?

Role-based E-learning: A Guide to Designing and Moderating Online Role Plays (Paperback)

A new book on role-based e-learning, from your truely, co-authored with Sandra Wills and Elyssebth Leigh will be available from Amazon from December 2010. From the Introduction:

This book offers an overview of a form of blended e-learning which provides students with authentic learning experiences through role-based activities. It describes a particular approach to learning design that places learners in roles requiring them to collaborate and communicate about actions and decisions within authentic scenarios created in online environments. The chapters offer advice, information and examples for educators moving role play into blended e-learning contexts and to those who are unfamiliar with role play. The book demonstrates in a practical ways how role-based e-learning builds on the pedagogical power of role play in face to face situations and shows how to add value to e-learning via wholly online and/or blended contexts.
Whilst this Introduction defines online role play in contrast to the more familiar mode of face to face role play, Chapter 1 Games, simulations and role plays positions this role-based e-learning alongside recognised learning designs such as problem-based learning and case-based learning and illustrates its connections with other online modes such as simulations and games. In addition it provides a more in-depth look at the educational rationale for role-based e-learning.
The three authors each have over twenty years experience with designing and researching role-based e-learning allowing them to describe examples of how role plays have developed over that period and been adapted as e-learning evolved. Altogether the book offers a comprehensive and non-technical introduction which is heavily informed by practice as well as research.

The book cites twenty-five examples, contributed by a network of international colleagues (listed in Appendix A). Examples cover a range of disciplines including: Education, Engineering, International Relations, Media, Journalism, Public Relations, Communications, Business, Environment, Health, Law, Language, Economics, History, Politics, and Geography. Many of these examples are described individually in Chapter 2 Examples of role-based e-learning to illustrate the possible similarities and differences and to compare the approaches of different role play designers from across the world.

Examples in Chapter 2 are referred to throughout the book and are labelled Example 2.1, Example 2.2 etc. In addition each chapter contains one or two examples relevant to the chapter’s theme and these are labelled according to their chapter number. The full description of Example 3.1 occurs in Chapter 3 but may be referenced in brief elsewhere in the book by citing its label (Example 3.1) in case the reader needs the full description again.

Appendix B contains a set of reflective questions for readers to use in reviewing each chapter. If this book is being used as a textbook in an education or design course, this appendix might lay the groundwork for group work and online discussion between learners. Appendix C describes a free role play available for educators to try with their classes.

A large part of the book is a practical guide to designing online role plays. Quality learning outcomes from this e-learning design depend on practical design choices. These decisions about design are overviewed at the conclusion of Chapter 2 and then described in detail in the next three chapters: Chapter 3 Designing online role plays, Chapter 4 Designing the problem and Chapter 5 Designing the roles and rules.

The design decisions that impact assessment are explored in Chapter 8 Assessing learning in online role play. Not all online role play designs require participants to be assessed however the learning design does provide unique opportunities to integrate powerful and authentic assessment tasks.

Meanwhile design decisions that affect the implementation and running of online role plays are explored in two chapters: Chapter 6 Moderating online role play and Chapter 7 Platforms for online role play.

A significant feature of role-based e-learning is that role play is a co-created learning activity. Once the educator has designed the initial scenario and roles, the remainder of the learning activity is further developed by the participants via typed dialogue in discussion forums. The success of this partnership between the learners and educators depends heavily on the experience and skill of the person running it, in this book called the Moderator.

Although cost-saving is not a primary reason for advocating online role play, co-creation also means that role-based learning can often be a low-cost educational technology, as outlined in Chapter 7, Platforms for online role play. Whilst the pioneering development of online role play has been text-based, and there are many advantages in this, online role play is now poised to engage with the exciting potential of Web 2.0 applications which support easy sharing of user-generated, multimedia content.

Innovation in teaching can be a time-consuming and risky venture therefore Chapter 9 Evaluating and researching online role play provides advice and support to educators needing to know that their design is effective, efficient, and easy to use. Examples and techniques in the chapter provide the evidence base for deciding whether it was worth the time and effort and what aspects could be improved next time.

The book concludes with a look at what impact current trends in e-learning may have on the future for role-based e-learning. While future development will of course be influenced by changes in the type of technology and how we use it, Chapter 10, Future trends for role-based e-learning, also looks at the potential impact of advancements, based on research, in both the way the learner-educator relationship is viewed and the role of educational institutions.

Converting classroom courses to online

Use a print-based framework for your finished product; however, augment the print-based material with short audio-video tutorials (created with Adobe Captivate) that show students the piece of software in action.

The context of why there is a need to convert from an existing instructor-led course to an online one is unclear, nor is the content and audience. It is very difficult to give a general advise on what is the best approach. However, in a training situation, we are not dealing with people who are 'blank slates". They are not here to "absorb information". "Using printed material and short audio-visual tutorials" is based on an information delivery model which seldom produces lasting changes.

This is a golden opportunity to rethink the kind of training which will produce lasting changes. The key to success in training is to utilise the existing expertise of the "learners" and generate an environment in which the participants can share, learn from each other and the new material to be discovered as they collaboratively work on tasks similar to the target situation when the training is completed. If someone can supply a concert example, I may be able to illustrate what I mean.
