Geography and History Education

Here are two useful sites. The first site provides a fun way to review geography. The second is designed to help K-12 teachers improve American history education. Enjoy!


I haven’t played Tetris (here and here) in a long time, so I couldn’t resist trying Statetris.


You determine how well you know the geography of a particular region by playing this Tetris-like game. You begin by choosing an area such as Africa, Brazil, Europe, France, Germany, Italy, Japan, South Carolina, the USA, or others. Then you choose the difficulty level (easy, medium, or difficult).
  • easy level: labeled shape … non-rotating puzzle piece
  • medium level: name only … rotating puzzle piece
  • difficult level: no names … rotating puzzle piece
Shapes fall from the top and you have to navigate them into their correct locations before the shapes reach the bottom. It's fun and a good review at the same time.

This geography review tool would work well with an interactive whiteboard. Go to http://www.teachersfirst.com/single.cfm?id=9282 to read the TeachersFirst review of and suggestions for using Statetris.


The National History Education Clearinghouse is a central location for K-12 U.S. history education. This is a rich site, definitely worth using by both teachers and students.

Resource categories include: history content, best practices, teaching materials, issues and research, TAH (Teaching American History) grants, and professional development.

  • History Content includes access to pre-approved history web sites and primary source archives, information about historic sites for field trips, research tools, online history lectures, web site reviews, a list of organizations with resources for teaching and learning American history, and an “ask a historian” option.
  • Best Practices includes sections on using primary sources, examples of historical thinking, and examples of teaching.
  • Teaching Materials includes sections on lesson plan reviews, gateway to history lesson plans, state standards, and ask a master teacher.
  • Issues & Research includes sections on issue roundtable, research briefs, and special topic analysis.
  • TAH Grants includes sections on the TAH project database, project spotlight, lessons learned, and the TAH listserv.
  • Professional Development includes sections on membership organizations, online courses, grants & fellowships, workshops & lectures, conferences, and calendar of events.

Computer Maintenance and Security

Atomic Learning is again offering (for a limited time) a free tutorial series. This time it’s a workshop on computer maintenance and security. Although the series is designed for computers with the Windows operating system, those using Macintosh computers will also find useful information.

The tutorial series examines backup, cookies, firewalls, free virus scanners, junk e-mail filters, malware, phishing, pop-ups, safer web browsing, spam, spyware, storage, safer passwords, uninstalling unwanted applications, and wireless network security. This workshop is worth checking for both you and your students.

Google Maps + wiki = WikiMapia

WikiMapia (http://www.wikimapia.org) is a collaborative mapping tool that combines Google Maps with a wiki system. Users can add information for any location on the earth to this online map and satellite imaging resource. More than 150,000 users have added more than 7,000,000 locations at this point.

Alexandre Koriakine and Evgeniy Saveliev created WikiMapia, one of the top 1,000 web sites visited. Their goal was to describe “the whole world." You can view this world with satellite, terrain, or hybrid maps. More than 60 languages are supported.

To add a location, click on Add Place and follow the simple instructions. You draw a rectangle at the spot, provide a title and choose a location type (such as museum). You can include additional information as well as a photo and/or a YouTube (http://www.youtube.com) video.

An upcoming place is a new place that needs to be verified. Locations added by new or unregistered users must be verified. That is accomplished by the location’s receiving enough positive votes.

Basic tools for measuring distance and land area, and mapping IP addresses to locations are available from the GeoTools menu at the top of the page. A GPS receiver can be connected to WikiMapia using a plug-in program (Windows only). To connect WikiMapia with a GPS receiver download the software from the WikiMapia site. Unzip it, start it, and follow the directions.

A WikiMapia data layer for Google Earth is also available.

I added our local historical society (Lake Township Historical Society) museum to WikiMapia as I tested it. Here’s an embedded portion of the WikiMapia map that includes the museum:


And here’s a link to the same site:
http://www.wikimapia.org/#lat=40.9263986&lon=-81.4046359&z=18&l=0&m=a&v=2

Classroom uses for WikiMapia by both students and teachers include…
• history,
• geography,
• science: coastal resources, landforms, changes of earth's surface,
• mathematics: latitude and longitude, and
• literature.

How would you use WikiMapia in your classroom?

❒ Write a blog?

You’ll find tips to help with many of these ideas in previous entries in this blog. Use the search box at the top of the page or the labels on the right side of the page to help you search through the blog to find entries on specific topics.


CUSTOM GUIDES
If part of your summer plans are to learn a new application or two, you may be interested in what I learned from Constance Brown. She told me about the Custom Guides web site. You can download and print--for free!--useful reference guides from this site. You can use these printable quick references or distribute or share them.

Some of the applications these custom guides are available for include…
  • Acrobat
  • Apple Mac OS
  • Dreamweaver
  • Fireworks
  • Flash
  • Internet Explorer
  • Microsoft Access
  • Microsoft Excel
  • Microsoft Office
  • Microsoft Outlook
  • Microsoft PowerPoint
  • Microsoft Publisher
  • Microsoft Windows
  • Microsoft Word
  • Mozilla FireFox
  • Photoshop
  • Photoshop Elements

CLIP ART
I’m always on the outlook for quality, free clip art which is appropriate for school use. I am delighted with what I found at http://www.pppst.com/clipart.html. An artist created the clip art for use by teachers and students. It can be used in the classroom, for homework assignments, and for projects. You can see some of the clip art in the poster in this blog entry. Categories include language arts, science, social studies, mathematics, holidays, and other subjects.


BOOK TO READ
One of my plans for this summer is to read Wikinomics: How Mass Collaboration Changes Everything by Don Tapscott and Anthony D. Williams.

I’ve read a lot about wikinomics. It’s time to read the book! Wikinomics describes
how to prosper in a world where new communications technologies are democratizing the creation of value. Anyone who wants to understand the major forces revolutionizing business today should consider Wikinomics their survival kit.

WEB 2.0 TOOLS
This wiki describes web-based tools and how they can be used in school. Much of the information is based on a survey of more than 600 school media specialists about the use of web-based tools. If you plan to learn a new application this summer, you might want to check out this site.


GLOGSTER
Did you like the poster at the top of this blog entry? You can use Glogster.com to mix graphics, photos, videos, music and text into posters to illustrate an idea or topic. This site is fun and easy to use. However, you’ll definitely want to check out the tools and the users’ samples which are displayed before using this tool with students.

Tutorials for Microsoft Word and Google Docs

Which word processing application do you use?

Do you use Word, the Microsoft Office word processing application? Have you been using it for a while, but would like to add some new techniques? Or have you been using another word processing application and would like to come up to speed with Word?

Would you like to experiment with an online word processor such as Google Docs?

These are certainly not the only options; however, let’s look at some tutorials for these two for the moment.

Microsoft Word
The versions of Word (designed for Windows) most likely being used now are Word 2003 and Word 2007. For Mac users, it’s Word 2004 and Word 2008.

Word 2003 for Windows
Denise Etheridge’s free tutorial (http://www.baycongroup.com/word.htm) provides a simple introduction to Word 2003. The style is illustrations mingled with text. Topics covered include: introduction (toolbars, highlighting, menu commands, new paragraphs), basic features (delete, insert, bold, underline, italicize, opening files, spell check, fonts and font size, saving files), paragraphs (line spacing, indents, alignment), tabs, bullets, printing, and tables (creating tables, navigating, entering and aligning text, adding rows, resizing columns, sorting, deleting, merging cells, headings).

If you have access to Atomic Learning’s subscription-based tutorial series (http://www.atomiclearning.com), you will find introductory, intermediate, and advanced instruction for using Word 2003. Also available at Atomic Learning’s site are tutorials for mail merge and newsletters. Atomic Learning’s tutorials consist of a series of short video clips and are always well done.

TeacherTube has two videos for Word 2003. Creating and Editing a Word 2003 Macro (http://www.teachertube.com/view_video.php?viewkey=fed5d5e93a98dc968ac2) demonstrates how to create and edit a macro and how to customize a macro button. Creating Name Badges (http://www.teachertube.com/view_video.php?viewkey=ee3ea4f42c748980eda8) is a “silent” video which demonstrates how to create name badges using mail merge (with the help of Excel). YouTube also hosts videos that teach a variety of techniques for Word 2003. To see what’s available on YouTube, simply do a search for Word 2003 at YouTube’s web site.

Word 2007 for Windows
This free tutorial by Denise Etheridge (http://www.baycongroup.com/wlesson0.htm) provides an easy-to-understand introduction to using Word 2007. Topics covered include: introduction (document views, keyboard shortcuts, new paragraph, ribbon, scroll bars, toolbar), basic features (bold, italicize, and underline, clipboard, cut and paste, delete, find and replace, fonts and font size, insert, opening a file, saving a file, spell check), paragraphs and styles (alignment, indent, line spacing, opening a blank document, styles), and bullets, page layouts, printing documents (bullets, page size, margins, page numbers, page breaks, preview and print documents). The style in this Word 2007 tutorial is the same as Etheridge’s Word 2003 tutorial: text and diagrams.

If you have access to Atomic Learning’s tutorial series (http://www.atomiclearning.com), you will find introductory, intermediate, and advanced instruction for using Word 2007. Also available at Atomic Learning’s site are tutorials for mail merge and newsletters. Atomic Learning’s tutorials consist of a series of short video clips and are always well done.

Bullets and More in Word 2007 (http://www.teachertube.com/view_video.php?viewkey=cb72fd897dacff6e9add) is one of the videos for Word 2007 that are available at TeacherTube. This video for beginners demonstrates selecting words, line spacing, adding bullets, and working with headers and footers. Creating a Basic Table in Word 2007 (http://www.teachertube.com/view_video.php?viewkey=3d18fdba8f98bfc6ab42) demonstrates how to create a table when using Word 2007. YouTube also hosts videos that teach a variety of techniques for Word 2007. To see what’s available on YouTube, simply do a search for Word 2007 at YouTube’s web site.

Microsoft Word 2004 for Macintosh
If you already know the basics of using Word 2004, Giles Turnbull provides some techniques that you might want to add to your repertoire: audio notes, scrapbook, and paste options. Ideas for using other Office products are also discussed in 21.5 Things You Can Do with Office 2004 (http://www.oreillynet.com/pub/a/mac/2004/08/03/ms_office.html).

If you have access to Atomic Learning’s tutorial series (http://www.atomiclearning.com), you will find introductory, intermediate, and advanced instruction for using Word 2004. Atomic Learning’s tutorials consist of a series of short video clips and are always well done.

Microsoft Word 2008 for Macintosh
Mactopia is a Microsoft web site for Macintosh products. At this site (http://www.microsoft.com/mac/help.mspx?product=Word&app=4), you can find instructions for using Word 2008, access to forum discussions, and technical support. Explanations are done with text and diagrams and are easy to follow. In addition to learning how to use Word 2008, you can pick up techniques such as mail merge, adding captions to a picture, creating form documents, and turning off auto features.

This Microsoft site for working with Word 2008 (http://mac.microsoft.com/MacOffice/UARedir.aspx?MODE=pv&CTT=InContent&srcid=b1c44fbb-18bb-4a80-94d9-53a8dea237101033&ep=4&locale=en-US&usid=36579005-ea6f-40cb-b411-8f869ecef292&clr=99-4-0&target=5979c9cb-f1f9-4543-abe1-6ae2172c23151033) has instructions for creating a document by using a template, adding clip art and photos, and adding a cover sheet and a table of contents.

Google Docs
Google provides an online word processor, Google Docs (https://www.google.com/accounts/ServiceLogin?service=writely&passive=true&nui=1&continue=http%3A%2F%2Fdocs.google.com%2F&followup=http%3A%2F%2Fdocs.google.com%2F&ltmpl=homepage&rm=false), that is free, easy to use, and can be accessed anytime/anywhere that you have Internet access. In fact, a new feature allows you to work on your Google documents even if you are not online. One of the best features of Google Docs is the ease with which you and others can collaborate on the same document.

Google does a good job of teaching how to use their online word processor, Google Docs. At this site (http://docs.google.com/support/?hl=en) you can take a tour to get an overview of Google documents, spreadsheets, and presentations online or start with the tutorials to learn how to get started (account and settings), work with documents (editing, printing, collaborating, importing and exporting), and more (mobile, offline, RSS feeds, and privacy). Or take your choice of videos created by users at the Google Docs Community (http://www.youtube.com/GoogleDocsCommunity) at YouTube.

Web Sites to Help Teach Mathematics

Last week I shared some interesting mathematics and science web sites that teachers and students might enjoy examining and then trying some of the ideas offered. Sometimes, however, we just need some help with the everyday teaching and learning of the standards for mathematics and science. So, today I’m sharing some mathematics sites that you might find helpful… and next week I shall share some science sites. Many of these sites will work well with interactive whiteboards.

To find these resources, I searched three of my favorite sites that continue to add quality web sites to their collections: the Ohio Resource Center, TeachersFirst.com, and the Ohio Treasure Chest of Technology Resources.


OHIO RESOURCE CENTER FOR MATHEMATICS, SCIENCE, AND READING
http://ohiorc.org/
The Ohio Resource Center for Mathematics, Science, and Reading continues to add new resources to their collections, so even if you’ve visited previously, be sure to stop by to check the new additions! This is one of my favorite sites because their review process assures that their recommendations are worth considering.

Mathematics Problem Corner
http://ohiorc.org/for/math/problem_corner/default.aspx
One of the newest features for mathematics is the Problem Corner. It has rich problems for grades 3-12. Browse all the problems or browse by grade and topic.

Thinkfinity Web Site
http://www.Thinkfinity.org
The Thinkfinity site has been redesigned and now links to the ORC main page. It includes resources from Illuminations (National Council of Teachers of Mathematics) and Science NetLinks (American Association for the Advancement of Science). The site has lesson plans and teaching materials that are of high quality.

High School Mathematics Program Models
http://www.ohiorc.org/pm/math/math_intro.aspx
ORC, teachers, and teacher educators have created pacing guides for Ohio’s Mathematics Program Models (http://www.ohiorc.org/pm/math/math_intro.aspx). ORC describes the Guides as including “topics, teaching tips, links to best practice lessons, and problems that engage students” in mathematics and higher-level thinking. A sample is available at http://www.ohiorc.org/pm/math/math_pma.aspx.


TEACHERSFIRST.COM
http://www.teachersfirst.com/
TeachersFirst is another of my favorite sites because they thoroughly review all sites which they post. They also make suggestions for using these sites in the classroom. I’ve recommended this site previously, but--like ORC—they also continue to add new, quality sites to their collections.

RainForest Maths: Interactive Mathematics Activities K-6
http://www.teachersfirst.com/archives/newsource.cfm?id=7248
This site includes numbers and number systems, operations and calculations, strategies and processes, patterns and algebra, measurement, space and geometry, chance and probability, data analysis, and money… and good to use with an interactive white board.

A Mixed Bag of Mathematics, Science, and General Interest Web Sites

I remember a certain weather reporter who would talk about a “mixed bag” of weather conditions that were heading in our direction. Well, today’s tech tip is a mixed bag of mathematics, science, and general interest web sites that are interesting and even fun.



The Hundred Greatest Theorems http://personal.stevens.edu/~nkahl/Top100Theorems.html

Having spent many years teaching mathematics to students in grades six through twelve, I could not resist a list of the Hundred Greatest Theorems. The chart includes links to many of the theorems and the mathematicians associated with them. Dates are also included in the chart.

I have taught some of these theorems, but certainly not all of them. The inclusion of the theorems in the list is based on "the place the theorem holds in the literature, the quality of the proof, and the unexpectedness of the result." Archimedes’ Area of a Circle, the Pythagorean Theorem, and Godel’s Incompleteness Theorem are a few of those included in the list.


Anita’s Origami
http://www.ulster.net/~spider/diagrams.htm

Origami Now!
http://pem.org/origami/

Two origami sites provide instructions for folding many interesting creations. The instructions for the first site are a combination of words and sketches. The instructions for the second site are contained in videos.


Optical Illusions and Mind Tricks http://www.lovethosekids.com/illusions/aaillus.htm

Enjoy this list of optical illusions. Can you explain how or why they work? Could your students draw some original optical illusions?


Wired Science
http://www.pbs.org/kcet/wiredscience/
This PBS site has links to science features, videos, blogs, and education helps.


Science 2.0
http://www.sciam.com/article.cfm?id=science-2-point-0&sc=rss
The April 2008 Scientific American has an interesting article about Science 2.0. M. Mitchell Waldrop writes about a new practice by some researchers of posting raw results online. How will this practice affect science discoveries and the scientists who make those discoveries?

Adobe Photoshop Express... Disappointment, Surprise, Delight!

Adobe has published a free, web-based, image-editing application. Adobe’s Photoshop Express joins several other image-editors already online. As soon as it became available, I examined it to determine how it compares with the online image-editor that I currently use… and to determine which Photoshop-like procedures I would be able to use with this new application.

I chose not to share my experiences as a tech tip at that point due to the Terms of Service. I was not the one to initially discover that the Terms gave Adobe more control over users’ content than many users would like; however, when I reviewed the Terms, I agreed that they were not what I wanted to accept. Adobe has since modified the Terms and, consequently, I can now recommend the application.

My first reaction was one of disappointment. Since this application is Photoshop Express, I figured I would be able to use layers. However, there are no layers.

As I tried various editing functions, I was surprised to see preview thumbnails of my image. I can click on the different thumbnails to see which result I like best. With some of the editing functions a slider is also available to help me choose my preferred result. The thumbnails help me make my choices.

Another good feature is the ability to undo choices I make… and not necessarily in the order that I originally make those choices! That, too, was a surprise.

Two pages of FAQs provide helpful information when you’re first learning the application. Some of what I learned from the FAQs includes…
  • I can play without an account, but I can’t work with my own photos without an account.
  • Photoshop Express currently works only with JPEGs.
  • I can upload multiple files at a time from my computer.
  • Photoshop Express currently works with Facebook, Photobucket, and Picasa.
  • When I upload a photo from my computer, I can select it in My Photos, and then choose to edit it.
  • In order to download my edited and saved photo to my computer, I mouse over the photo. That makes the options menu visible and then I can choose to download the photo to my computer.
  • Functions that are available include: crop and rotate, resize, auto correct, exposure, red-eye removal, touchup, saturation, white balance, highlight, fill light, sharpen, soft focus, hue, black and white, tint, sketch, distort, and pop color.
Photoshop Express is easy to use. Although some features that I would like are missing—layers, tools for drawing shapes, the ability to add text—some nice features that are included are storage space for photos, the ability to share photos, and slideshow settings for albums.

What delighted me was that I can pop color! I can’t do that with my current image-editing application. My purple water lily looks great in blue!

Inventors and Inventions

A colleague asked me for some good sites about inventors and inventions. As I gathered the resources I realized that this topic could be used effectively to help teach science, history, writing, mathematics, and language arts. Students can invent musical instruments, conduct experiments or demonstrations that illustrate inventions, produce plays about inventions and their effects on society, write biographies of inventors, create and trade inventor trading cards, create videos to tell the stories of inventors and their inventions, conduct oral interviews of living inventors, produce podcasts of those interviews, or write stories about how an invention could change the future. The following list of resources (with comments) could help with those projects.

Encyclopedia Smithsonian: Engineering, Industry, and Invention http://www.si.edu/Encyclopedia_SI/science_and_technology/EngineeringandIndustry_Technology.htm interviews with leaders and inventors: Bill Gates, computer history, Don Wetzel (ATMs), Marc Andreesen (Netscape); Latin American inventors; invention at play; sewing machines; more…

Link Extractor Lists Web Sites

Would you like a quick way to list all the web sites that are mentioned on a web page that you’re reading? The Webmaster Toolkit’s Link Extractor does exactly that.

I tested it with the 1-800-GOOG-411 web site. I entered the URL of the site…






… and it found nine HREF links.











Then I checked for SRC links…






… and it found twelve more links.












That’s certainly faster and more accurate than going through the web site manually. And it’s a lot easier!

[I read about this tool in an edublog, but —unfortunately— neglected to note which one. I think it was one of Vicki Davis’ links in her Cool Cat Teacher Blog.]
