Technology in use in Engineering

I have a Bachelor's degree in Aerospace Engineering from Worcester Polytechnic Institute and I worked for 10 years as an engineer before becoming an educator. I still do some consulting and keep up to date in the field. With all the talk about educational technology, I thought it would be nice to share some of the technology currently being used by engineers so that educators have an idea of what college students will be learning.

Engineers, like everyone else, use office productivity tools (MS Office, Google Docs), email, and the internet. In fact, the internet is one of the engineers' best tools. Research, online catalogs from vendors, online reference guides and calculators, and discussion groups and forums are all used on a daily basis.

Computer Aided Design (CAD) is the next major technology that engineers use. Products are designed in 3D on the computer, analyzed, fit checked, and simulated before prototypes are even built. Multi-physics simulation software, Finite Element Analysis, and Computational Fluid Dynamics software are critical to being able to design, analyze, and test products virtually before spending more money on manufacturing and live testing. They can analyze and simulate almost everything that a product would go through, virtually.

There is also Bill of Material (BOM) software to keep track of all the pieces and parts, Manufacturing software to help the engineers figure out the best way to build a product and then programming the equipment to do the work.

3D printers are used to make functional models of the product for early testing. They either strip away material, or lay down material (a plastic) to create the parts. These 3D printers can fit on a desktop. There are also 3D scanners that can be used to take a real part and turn it into a 3D model in the computer.

When I worked at Sikorsky Aircraft, we did everything on the computer. Design, analysis, simulation, manufacturing layout, communications, coordination, and more. Even our manuals and references were all online. If we printed something out, it had a watermark on it saying that the computer network should always be checked for updated information.

Computers and software have always been important in engineering, but as computers have gotten more powerful, so has software and the tools that can be used. Things change quickly, so engineers have to be able to learn new software and tools on their own.

As a high school physics teacher, I teach 90% seniors. This means that I am usually the last science teacher that they will have in high school (they may be taking two sciences). I try to expose them to project based learning (how WPI does things and how engineers work) and different types of software and systems that are out there for science and engineering. I try to teach them how to do their own research and how to learn things on their own, because I know that is what they will need to be able to do in college and in the workplace.

I also try to encourage students who are interested in and good at science to look at engineering as a career. Our world needs more engineers to solve the world's problems and continue with improving our standard of life.

Engineering is obviously not the only career field using technology - medicine, manufacturing, even retail, all use technology in ever increasing ways. This means that the more our students are exposed to technology, the better prepared they will be for college and the workplace.

College Necessities 1989 vs. 2009

I went to college from 1988-1992, at Worcester Polytechnic Institute, majoring in Aerospace Engineering. Technology has changed a lot since then and so have student needs at college. I thought it would be fun to compare the needs (and wants) of a college student in 1989 and now in 2009.

3.5" floppy disks for saving your work from the computer lab
notebooks - lots of them
3 ring binders to organize notes and handouts
graphing calculator
Tape recorder (record lectures)
Pens and Pencils
Post-it Notes
TV and VCR
Video Game console
Telephone for room
Books (leisure and reference)
Planner and Address book

Flash drive for backup
Laptop with CD/DVD drive and external speakers
Some notebooks and pens

That's all.

Think about it! The Smartphone is their phone, Walkman, graphing calculator, note taker, planner and address book, books (eReader), and lecture recorder. The laptop is their note taking tool and planner, DVD player, TV, eReader, reference, stereo, video game console and more. The notebooks and pens are for classes where the laptop doesn't work well for notes (like science and engineering) - however, a tablet PC with handwriting notes software would work for this.

Packing for college is much easier now. No more boxes of books and notebooks, stereo and box of CD's, boxes of VHS tapes, VCR, TV...ugh. Now, one backpack could carry everything but their clothes.

I'm jealous! I remember lugging multiple notebooks and textbooks around and a planner. Lots of floppy disks for my data, and more. And forget trying to organize a party or how to meet up with other students. Cell phones, Facebook, Twitter, and more have made things so much different now.

Lifehacker - tips and information for all of life

Lifehacker is one of those web sites that has so much stuff you don't know where to start.

Lifehacker features tips, shortcuts, downloads, and information to help you get things done smarter and more efficiently. Lifehacker has won many awards and accolades and I always find good ideas or resources on the site.

Software, web sites, products, tips and tricks, and other ideas are published each day (sometimes more than 20 articles per day). They range from web browser extensions, to how to maintain a computer, to how to best grill a steak to fixing things at home, and more. Chances are if you have a question, they have an answer.

I highly recommend subscribing to Lifehacker and browsing the site. There are always new jewels to be found.

Harvard WIDE World Online Classes

It is rare that I mention, let alone recommend, something that costs money, but this one is well worth it.

Harvard's Graduate School of Education has a great online program called WIDE World.
WIDE World offers online certificate courses for educators on topics ranging from Teaching for Understanding to Differentiation to Teaching with New Technologies.

They have courses of study, or you can take individual courses that you are interested in.

I have taken Teaching to Standards with New Technologies 1 and 2. I found the courses to be well designed and planned out. Each course had readings from books and web sites, online activities, research and assignments, and online discussions as part of the program. WIDE World emphasizes Understanding By Design and we used the UbD lesson format in our assignments.

There is a discounted fee for people who sign up as part of a group.

I recommend this program to my colleagues.

I would like to hear feedback from any readers who have taken courses through Harvard's WIDE World program.

Lovely Charts - Diagram service

Lovely Charts is a free online service that allows you to easily create charts, diagrams and more. Flowcharts, site maps, organizational charts and more are easily created on the site.

It is very easy and intuitive to use and Lovely Charts will suggest certain designs and components based on the type of chart you are trying to create. I found it much faster to use than Inspiration to create a site map to layout a new web site I am working on.

The built in graphics and functions are also very powerful and well done.

I recommend this to anyone needing to create charts or flow diagrams.

Below is an example of an organizational chart done in Lovely Charts.

Convert PDF files to Word Documents

PDFtoWord is a free site that converts PDF files into Word documents.

This comes in handy when you have a PDF file that you need to edit and change and you don't have the proper, and expensive, software.

It's very easy to use. Go to the site, select a file from your computer to upload and convert, and enter an email address where you want the Word document sent. That's it.

I used it to convert a 9 page, 3MB PDF file and it took about 15 seconds to upload. The converted file did not show up in my email inbox until later that evening. (it was graphic intensive too).

The converted file was pretty accurate with almost no errors, which I manually fixed in a few minutes. The quality of the conversion was really good.

Remember also that it will not be able to convert a file that was only an image, like a file that was scanned. It will simply put that image as an image in a Word file.

This is really handy for taking files that were created with a print conversion (like CutePDF) or from Acrobat and making them editable in Word. If someone created the PDF file by scanning a document, this will not convert it back since the scanning process converts everything into one image.

It's not bad for free. You definitely don't want to use this if you need the file converted immediately. You will want to plan ahead due to the delay in getting the file converted and the fact that you may have to do some manual editing of errors.

Free my PDF (from restrictions)

Free My PDF is a very useful site for those of us that deal with PDF files a lot. Many PDF files that are unlocked (you can open and read them) sometimes have restrictions on printing or copying text from the file. Free My PDF can remove those restrictions.

It is very easy to use. Go to the site, select the file you want modified, and click "Do It". You will then be able to download the unlocked file.

If you need a password to view the PDF file, you can not use this service. It also can not be used for illegal or immoral uses. In other words, you can't use this to violate copyright laws or take someone else's work.

Sometimes, these copy and print restrictions are in a file completely by accident because the person creating the file forgot to change the settings. Other times, you simply need to print or copy something for your own use. For example, a PDF file from a financial institution to me, with information about my account, would not let me copy or print. I wanted to copy part of it for my own records and print a hard copy for easy reference. I used Free My PDF to do that. No laws or ethics violated.

Try it out.

Here is the legal info at the bottom of the page:
An important note: There are many valid reasons to want to remove a password from a PDF (Ask your favorite lawyer about copyright and fair use, or Google it), but there are also many bad and illegal reasons. YOU MAY NOT USE THIS SERVICE FOR ILLEGAL PURPOSES. You also should not use this service for immoral puposes (it's not always the same). The owner of this site takes NO RESPONSIBILITY for the files processed on the site or generated by it, or anything else related to your usage (legal, technical or otherwise). Use it at your own risk.
The writer of this blog also takes no responsibility for your use of Free My PDF.

Palm Apps for Education

(Treo 755p, Treo Pro, Pre, Centro, Pixi)

The iPhone and it's apps always seem to be discussed on the web. I don't use an iPhone, and most of my colleagues and students don't have them either. There are plenty of Blackberry's, T-Mobile G1's and Palm smartphones around though. Since I use Palm phones, I decided to showcase some applications on Palm phones that are useful in education.

Palm's two new phones are the Palm Pre and Palm Pixi, which both run on Palm's new operating system, WebOS. One of the unique features about WebOS is the ability to multi-task using cards (similar to windows on a PC). While WebOS only has about 700 apps and another 350 homebrew (unofficial) apps, there is one application that is very useful. Classic allows WebOS phones to use most of the 20,000 PalmOS apps that exist.

PalmOS was Palm's older operating system that ran on the popular Palm Centro and Treo smartphones. There are millions of Centro's and Treo's out there and Palm's PDA's (TX, LifeDrive, and others) and there were tons of educational applications and lesson plans written for Palm devices.

Basic Applications: contacts, email, web browser, text messaging, camera, phone, tasks, media players, note taking, and lots more, including Evernote, Twitter, Facebook and Google.

Educational or useful in Education: (both platforms)
Docs to Go (Word, PowerPoint, and Excel)
Teacher and Student organizers

WebOS Resources: (Palm Pre and Pixi)
Precentral - single best resource for Palm Pre and Pixi and WebOS
Homebrew apps for WebOS - over 300 including conversion calculators, organizing tools, and periodic table.
World Factbook (information about countries)
Classtracker (student grade and assignment tracker)
Word of the Day - great resource for helping students learn new words and strengthen vocabulary
Unit Conversions - converts units

WebOS has hundreds of applications, many useful for education. Every week, more and more applications arrive in the app catalog, so there is always something new to check out.

The web browser in WebOS is excellent, rendering web pages like you were on a desktop computer. This allows teachers and students to access all of the great web pages and web based applications that exist for education. Adobe is also bringing Flash to WebOS soon so Palm Pre and Pixi owners will have the ability to see Flash content right on their device.

PalmOS Resources: (can run on WebOS with Classic installed on Pre or Pixi)
Centro, Treo, TX, T3, E2, Lifedrive
Listing of Palm educational applications - dictionary, unit conversions, calculators, translators, and more
Educational Applications for Palm - maps, productivity, games, and more
Due Yesterday - student organization, due dates, homework tracking and more
Student Mate - student homework and assignment tracking
K12 Handhelds - site has listings of Palm OS software for education, organized by category. The site also has ideas on how to use Palm OS devices in education.
Inspiration for Palm OS - graphic organizer and visual planner.
PalmGear - PalmOS applications
Handango - PalmOS applications
Teacher's HandyPack - includes time table, lesson planner, teacher planner, and student and class manager
Gradekeeper - electronic grade book. Sync's to desktop.

Applications for Palm OS range from calculators, conversions, periodic tables, study tools, flash card tools, quizzes, student organizers, teacher tools, language translators and much, much more.
Many of the PalmOS applications also have desktop counterparts (like Gradekeeper) and you can sync your handheld's information to the desktop. This acts as both a backup and it is easier to view and edit information on a desktop vs. a handheld.

This is only a small sampling of the thousands of applications available for WebOS and PalmOS. So you can see that Palm and WebOS have lots of applications that can be used in the classroom or for educational purposes. Android (Google's mobile phone application) and Blackberry do too.

I don't believe in schools requiring students to use any one product or software type because it becomes a defacto endorsement of the product and limits student choice. Instead, I think schools should use platform-independent tools (web based) or have lessons that allow student choice in which applications they use for class work.

Smartphones are a great educational tool. They are mini computers with the ability to do almost anything a student needs to do - write a paper, web research, graphing calculators, and much more. Schools shouldn't be outlawing cell phones and smartphones, they should be figuring out how to leverage them as learning tools.

nextSTEP magazine and site - after high school...

nextSTEP magazine is a great resource for high school students. The magazine itself is not free, although many schools get bulk subscriptions. Their website,, does have a lot of free resources for students.

Their tagline is "your life, after high school" and the magazine and web site have advice and information on careers, college planning and more. College search, college planning steps, career descriptions, articles on college life, careers, how to be successful in college, and much more are all on the site.

Our school has a bulk subscription, so the students can pick up a copy in the counselors' offices. Many of the students prefer to just go to the web site. The site has more detailed information than the magazine, along with videos and links to other resources. The site does has all of the articles from the print magazine.

This is a must have resource for high school students. - Free College service for students is a free service for students in high school applying to college. Students can connect with over 700 colleges that participate with Zinch, create a profile of themselves on the site for colleges to see, and even get information on financial aid.

Some of my students have used it before and found it easy to use and helpful in their college search and application process.

Readability - clean up web displays for better reading

Readability is a nice piece of free technology. It installs on your web browser as a bookmarklet and then will take a web page and get rid of all of the flashing ads and other distractions and just leave the text behind to make it easier to read. You set up a free account and you can select how you want it to display the text. It is very easy to use. It is not 100% perfect, but if it there are errors on the screen, just reload the original web page.

Below is an image of an article on my local newspaper's web site and then below it is the article after Readability was used.

(Thanks to my Twitter PLN for telling me about David Pogue's article in the NY Times about Readability).

What do you think? I think it makes reading things online much easier on the eyes and may prevent some people from printing things out to read them.

Web 2.0 Conquering Technophobia

Many teachers are intimidated by Web 2.0 technologies, or just don't know how to get started using them.

Discovery Education has a new free resource that can help these teachers. Web 2.0 Conquering Technophobia is great resource for teachers. It has lesson ideas, activities, explanations of Web 2.0 technologies, and more to help teachers learn how to use these resources in their classroom to improve teaching and learning and engage their students. Our students use a lot of these technologies already - why not use them in school?

There is also a downloadable PDF file with terminology, definitions and explanations.

The resources include lesson plans, activities, all about computers, links, and videos about different Web 2.0 technologies and how they are being used in the classroom.

You can also browse other free education resources while on Discovery's site.

iSpring - Free PowerPoint to Flash converter

I just learned about iSpring Free, a free PowerPoint to Flash Converter from the Connecticut Discovery Educator Network. It is easy to use and free. What a great way to share PowerPoint presentations on the web or in other applications. (once again, my PLN comes through with great resources).

It is a free download from the site. Install the software, open your PowerPoint presentation, click Quick Publish, and you will get a .swf file from your presentation. It will install a toolbar in PowerPoint. The toolbar has the Quick Publish button, as well as the ability to insert Flash and YouTube videos into your presentation.

I converted a 162 slide PowerPoint presentation (32 MB) to flash in 5 minutes. Not bad at all.

Converted file:
Very easy to use, quick, and FREE.


I recently heard that a college professor teaching a class for soon-to-be teachers had a class period devoted to educational technology. At first, I thought "Great - there is so much to share with these future teachers. They use technology now and he can show them how to adapt it to the classroom."

Then, I found out what he actually did. He told them about interactive white boards and Inspiration and told them that if they find something good, they should buy it. Then, he took them to a computer lab and had them search for "cool sites" and only gave them one as an example.

ARGH!!! This was so frustrating to hear. First, interactive white boards are all over the place and well known. Take a few minutes to talk about them and their use in class. There are many brands, so spending any time on one brand is not useful.

Second, Inspiration costs money. If a district doesn't already have it, teachers should use free versions like Xmind and Gliffy. ( and

Third, he said to buy things!! Schools are always short on money, especially in today's economy. There is so much available for free. Why pay for anything!?

He never gave them an ideas on using social media in the classroom or actual applications of technology in the classroom. This was very frustrating to hear. I did pass more information on to some of the students and I hope that things will change in that class in the future.

PBS Teachers Activity Packs

PBS Teachers has some great activity packs for teachers to use with their classes.

They have packs in arts, health and fitness, reading and language arts, science and technology, and social studies.

The activity packs have PBS resources, such as videos of PBS shows like NOVA, web links, and lesson plans for each topic. There are activities for different grade levels also.

These packs are great ways to have a multimedia, project based lesson for your class.

British Broadcasting Company - Education Resources

The BBC web site has clips from some of their shows, news, history and tons of resources for educators and students.

BBC Learning - information and resources for adult learners and children.

BBC School - games, video clips, classroom resources and lessons and much more. I very quickly found some great resources to use in my physics classes.
