More Trouble: Challenges of Teaching English in China

Met today with someone who had come to China with a major program to teach English. Heard some pretty troubling stories. Heard that administrators of the program have not been to the majority of the schools where they place teachers, so they don’t really know if the housing is adequate, if the conditions are safe, if there is any heating, or if the food provided is edible. Teachers can be subject to grueling conditions in remote and difficult places, much longer teaching hours than promised, with random changes in schedules that wipe out personal plans.

If your program won’t tell you where you will be placed until you are here and can’t provide you references from people who have been to same place, be very worried. The numerous problems that young people face when they come to teach English in China are quite discouraging. Don’t come here without knowing what it will be like. Don’t go with a program that will put you in a remote situation without support, help, and structure.

Insanity in Seattle

I received email from a parent in Seattle about the battle many parents have been fighting with the school district there. These parents have pulled together a lot of information showing that the block schedule system in Seattle has fared poorly and needs to be changed. “The group is at an in pass with the Teachers and the District over the schedule which has been in place for 13 years. No
matter what facts we bring to the table – internal and external – they do not listen.”

Here’s my response:
Seattle? Isn’t that the school district that issued a crazy definition of racism that included “future orientation” and individualism? If so, you’re dealing with insane people that aren’t going to be persuaded by facts. But they are likely to respond to politics, so organize and get parents coming in to talk and pressure them. Get a big group to show up at a Board meeting. Write letters to them, publish letters to the editor, etc. I think the key will be getting parents to care and be involve and make their voices heard. Ditto for contacting state legislators.
Insane people don’t listen to facts. Very sorry about that!!

Thinking of a Career? Consider Geology

Surprising fact: there is a shortage of geologists for companies that do exploration and mining of natural resources like gold, silver, and oil. According to precious metals expert Jim Willie CB:

Don Lindsay, CEO of Teck Cominco, paints a bleak labor picture… Lindsay traced the origins of the labor shortage back to 1997. According to him, the feeder systems were disrupted by the Bre-X scandal, the Asian Meltdown, and the commodity bear market. He expects demand to remain robust from China. Keep in mind that over two thirds of geologists in the world hail from Canadian schools. So if professional shortages exist in Canada, we have a very large problem indeed. Mirroring the crude oil roughneck labor shortage is the mining labor shortage. Another parallel exists. Lindsay points out that within a decade, 60% of all Canadian scientists working the geosciences will be at least 65 years of age. The overall impact is surely that new mine deposits will take longer to find, longer to produce, and cost more.

This is great news if you’re willing to pursue a career in geology. Many of the leaders of mining and exploration companies had their start as a geologist. If you love the outdoors and believe in work that really creates wealth, consider geology.

For investing, the shortage in skilled labor for mining means lower production in the future, and that means that prices of commodities are going to face even more pressure to go up. This is a great time to be heavily invested in gold and silver bullion, energy stocks, precious metals stocks, and uranium stocks like Dennison Mines (DNN) or my favorite, Abaddon Consolidated Resources ( or ABN on the Vancouver exchange).

Title: Engineering with Mathcad: Using Mathcad to Create and Organize your Engineering Calculations
Author: Brent Maxfield, P.E.
Publisher: Elsevier, © 2006
ISBN-13: 978-0-7506-6702-9
ISBN-10: 0-7506-6702-8
Number of Pages: 494

Brent Maxfield’s Engineering with Mathcad is a valuable contribution to the engineering community that may do much to help those in engineering and the sciences in general jumpstart their efforts to learn and apply Mathcad, or to help long-time users strengthen their skills. The book is accessible, engaging, and written from the perspective of one who has dealt the practical aspects of Mathcad for many years. It comes with a useful CD having a handbook and all the examples in the text, allowing the users to easily follow along and work with the material being discussed. The CD also can be used to install Mathcad 13 for PC or Mac with a 120-day academic license.

The book covers a broad scope of material effectively, and should provide useful new insights even for power users. However, the book is not intended to provide a comprehensive guide to the functions and plotting features of Mathcad. For example, there is no significant discussion of solving differential equations. Indeed, many of the engineering applications covered are relatively basic, with the emphasis being more on how to use Mathcad effectively rather than how to tackle complex engineering problems. Given the burgeoning scope of Mathcad’s tool and the many powerful features it has that experienced users may have been missing, Maxfield’s approach represents a reasonable editorial decision to cover Mathcad broadly rather than to teach engineering mathematics or dive into the complexities of any of the numerous areas of interest in engineering.

The book may be especially valuable for those who are relatively new at Mathcad or who, like myself, have Mathcad experience but may not have used it for some time and need a refresher. But a carefully selected swathe of sophisticated aspects of Mathcad are treated that may be helpful to longtime Mathcad users who simply had no idea about some of the tools and capabilities they were overlooking.

With his years of Mathcad experience, Maxfield offers many tips, sometimes subtle, to guide users in creating worksheets, preventing errors, maintaining readability, selecting useful variable names, and so forth.

While the companion CD is useful and highly appreciated, advanced engineering students who are facing challenges with differential equations or other common topics would clearly benefit from additional more advanced sample worksheets. I think future editions of the book would do well to add additional workfiles on the companion CD. When I saw the entries on the CD for chapter 24, hinting at pages on seismic loads, beams and joists, etc., I though such examples might be there, but they are just placeholder pages for demonstrating the use of hyperlinks in a table of contents.

Indeed, for the future, not only would I recommend a more extensive set of examples on the CD, but also the addition of a Website where registered owners of the book or others could contribute solutions, discuss the text, and look at more detailed and complex examples, or receive additional tips from the author.

In general, I recommend Maxfield’s book as an easy-to-read, well organized guide to help a wide range of Mathcad users learn techniques useful for engineering and many other fields as well.

A few minor quibbles: The chapters entitled “Useful Information” could use more descriptive titles, or be added as sidebars or summary sections elsewhere. I think they create a confusing table of contents.

For engineering calculations, the precision of computations may be important. I did not notice a description of Mathcad’s limitation of 15 digits. “Precision” is not an entry in the table of contents (though the term is a paragraph header on page. 98). Pp. 102-103 would have been one good place to discuss this.

Some discussion of differential equations would be helpful.

Organizationally, I also think the first chapter might well contain a rapid-fire overview of some of the features of Mathcad to give those new to Mathcad but with advanced engineering and scientific skills a strong flavor of the power of this sophisticated tool.

And perhaps a list of additional online resources would be good – most preferably a reference to a Website prepared by or for the author that can be updated with the best online resources, additional worksheet examples, corrections of any weaknesses in the text, etc.

In general, I congratulate the author for an excellent book that I think will be helpful to numerous Mathcad users.
