Free Stuff for Teachers, Homeschoolers, and Students - 2011
An Educators' News Feature
August 23, 2011

This is page 2 of a look back at the freewares, free web sites, open source applications, and a few other goodies that have appeared on Educators' News over the last twelve months or so. If you somehow wandered into the middle of this column, it may make more sense to start with page 1.

November, 2010

National Archives DocsTeach

National Archives Docs TeachThe National Archives opened a new web site, DocsTeach, last fall. According to New online tool helps teachers use primary source documents, the site helps "educators teach with primary-source documents...explore documents in a variety of media from the National Archives holdings," and has "online tools to help teachers combine these materials and create engaging history activities for students."

Washington's annotated draftExamples of documents from the news story include George Washington’s annotated draft of the Constitution (shown in part at left), the canceled check for Alaska, Chuck Yeager’s notes on the first supersonic flight, and President Richard Nixon’s resignation letter.

I poked around the DocsTeach site a bit and found it fairly easy to navigate. Being a bit of a history buff (my college major was U.S. and World History), I got pleasantly sidetracked several times from writing this post while exploring some of the activities provided. While I was a bit put off that I had to register (free) to see the full list of activities for each subject, I had a good time exploring Assessing Richard Nixon’s Presidency and Comparing Civil War Recruitment Posters. I did have to follow a number of links before finally arriving at JPEG and PDF versions of the recruitment posters shown (and linked) below.

Images for Classroom Use

Royalty-free and hassle-free images for the classroom used to be hard to come by. Even with the fair use principle, teachers wondered if they were inviting trouble by using a copyrighted image on their web page or site. The emergence of several free image sites along with greater use of Creative Commons licensing has greatly eased the job of finding free images to use in the classroom.

Pics4Learning

My Pics4Learning PageSpiderI seem to mention Pics4Learning about every six months or so on this site, usually just after I've uploaded something to them like the spider shot at right. Pics4Learning is an excellent "copyright-friendly image library for teachers and students." While there are lots of photo sharing sites online, I especially like Pics4Learning's clear, no nonsense statement about the use of photos posted to their site: "Unlike many Internet sites, permission has been granted for teachers and students to use all of the images donated to the Pics4Learning collection."

While their growing collection of free photos for classroom use isn't the largest repository around, it has a lot of useful images that can be browsed by subject or searched for by keyword. All uploaded photos are screened for acceptable content, making the site safe for student use.

One nice wrinkle about Pics4Learning is that if you upload your own images or know the photographer's name, you can search for them by name. Above left is the first page of my listing of photos contributed to Pics4Learning.

Photos8.com

Photos8.comA link on Mrs. Smoke's Making Teachers Nerdy: Top 20 Websites No Teacher Should Start the 2010-2011 Year Without led me to the Photos8.com site last June. Photos8 is a free stock photo site, but it's a bit unusual in that it doesn't seek photo contributions. All of the photos are the work of Sam Mugraby, who shares them for folks to use commercially, on web sites, in the classroom, as wallpapers, and so on with minimal restrictions. The last time I checked, the site showed 13,314 photos available for download! Do note that you have to hunt through some advertising to find the download link for each photo.

Skindiver from Photos8.comI looked at some of Sam's flower, insect, and people photos from a photographer's point of view and was impressed with his work. The composition, exposure, and color are excellent in most photos, and they are offered at a size and resolution that allows one to work with large or small printed images. The skin diver shot at right downloads at 2850 x 1900 pixels (reduced here to 400 x 267 pixels).

Nerdy Photographer Comment (and some sneaky embedded advertising): Sam works with a Canon EOS 40D camera. I was pleased to see one of his many lenses is one that I use and really like, the Canon EF-S 17-85mm f/4-5.6 IS USM.

Creative Commons Licensing

Creative Commons licensing has grown in popularity over the last few years. It allows a photographer or photo owner to set less restrictive rights on work than a blanket copyright does. Probably the best place to get a feel of what one can and can't do with images licensed via Creative Commons License is the Flickr Explore/Creative Commons page. The Creative Commons Search page can quickly get one going on finding the right image to illustrate student handouts, Powerpoints, or even feature stories about free stuff for homeschoolers, students, and teachers. It took me just a few minutes to locate a shot by Mel Silvers of the flooding caused by Hurricane Katrina using the Creative Commons Search and Flickr.

Desktop Photos and The Cutting Room Floor

Several years after launching Educators' News, I decided to share some of my better photos for others to use as wallpapers or Desktop Photos on their computers. In July, I added another free photo download page, Desktop Photos: The Cutting Room Floor. I use it for photos bumped from the main Desktop Photos page when I add new stuff and for photos awaiting placement on the main page (have to have several at a time to fit our table format).

For Earth Day this year, I decided to share some of the shots available on our Desktop Photos page on Educators' News...and here.

My "use" statement at the top of the Desktop Photos page is pretty clear:

All photos on this page are copyrighted, but may be used for desktop photos without permission or payment. All other use requires prior consent, massive royalty payments, your left pinkie finger... (Actually, I'm a pretty soft touch on non-commercial use of my photos. Just , please.)

But if you're not going to publish your classroom stuff and need to use one of my images, I'll never know. Smile

Free Computer Training

A posting on the HECC listserv led me to GCFLearnFree.org, which offers free computer training, including reading and math online tutorials for adults.

Scienceman

Scienceman.comEarly in November, I was delighted to discover that Scienceman Joe Martha was once again regularly posting online. His long-running Scienceman.com site now serves as a jumping off point to his Scienceman's Blog, Scienceman Video Channel (on YouTube), Reviews and Articles, and tweets.

I think the first time I linked to Joe's site was in 2001. He had done a review of some then, cutting-edge technology: a microscope that could display its view on one's computer and even project it in the classroom. I'd commented at that time on Educators' News:

 

This is the kind of classroom technology that gives "throwing money at the problem" a good name! I can remember trying to get a class of 25 sixth-graders to each take a quick peek at a euglena through a microscope before it swam out of view. Joe says, "The best part of this camera is the tremendous images it creates, and it's slick ability to get those images onto your computer screen via an integrated USB port."

We've obviously come a long way since those early, exciting days of computer technology in the classroom.

From Joe's Twitter page, I quickly found myself jumping to a page about burning water in homes in the Rosebud River Valley, east of Calgary. After that, I got lost in the Rally to Restore Sanity and/or Fear: A Comprehensive List of Signs. From the extensive list, I'll share just five of my favorites.

  1. Fight illegal migration: demand Canadian geese show us their papers
  2. Abalish the Dapartmint of Edukashun
  3. Everything on this sign is spelled correctly
  4. Facts have a well known Liberal Bias
  5. I already regret choosing to carry this sign all day

Science Girl

Scientific ExplorerScientific ExplorerSeveral months after discovering the rebirth of Joe Martha's Scienceman site, I read his tweet about Science Girl's new Scientific Explorer site. Science Girl, of course, turned out to be Joe's wife, Gale. She states on the site, "My goal is to bring you the most up-to-date ideas in science in an understandable format. I start big with my first series: The Universe. Have fun exploring!"

The first posting I read, The Northern Lights, was chock full of gorgeous photos and illustrations of auroras. Other postings are pretty much text only, such as Very Hot, Very Cold - Superfluids Demonstrate the Strangeness of Atoms. Another series, Secrets of the Solar System begins with Mercury and goes on from there.

PBS Student Reporting Labs

An eSchool News article, PBS NewsHour launches student reporting website, tells of PBS NewsHour's Student Reporting Labs site that "connects students with professional mentors at their local public broadcasting station to produce original news reports on important national issues." Beta tested with just six schools last year, PBS is opening up the program to other schools this year, offering "technical instruction on the use of cameras and editing equipment...meaningful focus on understanding the role of journalism in society and developing broader communication skills, including listening, asking questions, public speaking, and finding, analyzing and evaluating the quality of information."  

February, 2011

I apparently got wrapped up in all the political stuff going on in education during January and February, so there's only one freebie item from that period!

Free Letter Tracing App

ABC Letter TracingCritical Matter's ABC Letter Tracing – Free Writing Practice for Preschool iconmay have more use for your preschool children or grandchildren than for in the classroom. It's a free, new app for iPhones, the iPod Touch, and the iPad that gives an audio pronunciation of letters along with the opportunity to trace both upper and lowercase letters.

I thought the audio on the app was broken until I realized my iPhone was on vibrate! I also thought the app was just so-so...until one of my granddaughter's tried it and loved it.

March, 2011

What Was That Bright Light in the Sky?

NASA All Sky Fireball NetworkI spent a good bit of time on our back porch on an unseasonably warm night in March enjoying both the warmth of the winter night and an incredibly clear view of the constellation Orion. While watching the night sky, I saw a faint meteor move through the constellation. I thought, "Wow! A meteor!" I continued looking for another thirty minutes and saw two more vary faint streaks near Orion.

When I came inside, I began googling for "minor meteor shower" and the like. I could hardly believe I'd been fortunate enough to see three meteors in a little over a half hour. While there wasn't a major or minor meteor shower going on that night, I did find an appropriate page on Science@NASA, What's Hitting Earth? On that page, Dauna Coulter begins the piece, "Every day about 100 tons of meteoroids -- fragments of dust and gravel and sometimes even big rocks – enter the Earth's atmosphere."

Coulter goes on to tell about a new effort and web site, NASA’s All Sky Fireball Network. The site asks and attempts to answer the question, "What was that bright light in the sky last night?" The network is in the process of deploying 15 "specialized black and white video cameras with lenses that allow for a view of the whole night sky overhead." Three cameras are currently in service. They have overlapping fields of view, so the same fireball can be detected by more than one camera. That allows NASA scientists to calculate the height, speed, orbit, and sometimes the source of the meteor. 

I gave the site a try, only to realize that the meteors I'd seen were not bright enough to be recorded by the All Sky Network. They were about the fourth magnitude, while the network records meteors at or greater than the magnitude of Venus (-4.89 at its brightest). So while my sightings weren't confirmed by the site, it was a cool web exploration. And it's one more tool that could prove useful to teachers.

Sites of the Week

GeoGebraArcademic Skill BuildersOne of the places I frequently visit in search of good educational web sites is the eSchool News Site of the Week page. I found a couple of items there in March that might prove useful in the classroom. Free math software helps students from elementary school to college tells about the GeoGebra site and application "that joins geometry, algebra, tables, graphing, statistics, and calculus in one easy-to-use package." GeoGebra is available as a web app, an applet, or a downloadable application that "can do constructions including points, vectors, segments, lines, and conic sections as well as functions, which can be altered dynamically by mouse afterwards." Broken Airplane's 7 Steps to Interactive Math with Geogebra: The Basics adds to the considerable online documentation available.

A second goodie comes from Arcademic Skill Builders releases free educational video games that tells of a bevy of "web-based video games that help students practice basic math, language arts, vocabulary, and thinking skills while in the classroom or at home." The Arcademic Skill Builders games include good directions embedded in each online application.

Finding the Fun in Immunology

Sorry, but I just couldn't resist using one of the catch phrases for the Immune Attack (IA) learning game for a headline. In this free learning game, students "must navigate a nanobot through a 3D environment of blood vessels and connective tissue in an attempt to save an ailing patient by retraining her non-functional immune cells." The creators of IA seem to be continually looking for classes of middle and high school students to play and evaluate the game to help guide the development of version 2.0. "A small compensation...is offered" for classes participating in the test. And while the title Find the Fun in Immunology is a bit geeky, FAS's Melanie Stegman does make her case for it well:

 

Immunology is fun. Immunology involves watching cells identify and destroy other cells. These cells appear to be very similar to every other cell in the universe. These cells have outer membranes, nuclei, DNA and proteins that are almost indistinguishable from every other cell.

The questions are why this particular cell kills bacteria. Why doesn't this cell kill all types of bacteria? Why does this cell in some people, not kill bacteria? The answers involve making endless comparisons between healthy and sick patients, between pathogenic and non-pathogenic bacteria, between humans and mice and between mice and flies.

So, Immunology is a puzzle.

I sent Melanie an email that prompted some good news. Since my newest PC is too old to run Immune Attack (I tried.), and I work primarily on a Mac, her prompt response was welcome: "You will love Immune Attack 2.0. It will be PC, Mac and Browser based. :-)."

Resource Site Bonanza

Instructional UnitsAn eSchool News article in February drew a lot of great comments from teachers about their favorite educational resource sites. I finally got around to chasing some of the sites down in March and found, not surprisingly, that teachers may have a lot better handle on what may be helpful to them than we online writers. The TeachersFirst site was recommended by Fran Lo (francesblo). From the intro page:

 

TeachersFirst is a rich collection of lessons, units, and web resources designed to save teachers time by delivering just what they need in a practical, user-friendly, and ad-free format. We offer our own professional and classroom-ready content along with thousands of reviewed web resources, including practical ideas for classroom use and safe classroom use of Web 2.0. Busy teachers, parents, and students can find resources using our subject/grade level search, keyword search, or extensive menus.

TeachersFirst.comAs I dipped into the site, I first took a look at their TeachersFirst Instructional Units page. I selected two titles to explore further, and like Dorothy in the film, Jerry Maguire ("You had me at hello."), I was hooked when I saw the listing of People with Dreams (and their obstacles) in the lesson, They had a Dream Too: A Project on Overcoming Obstacles for Grades K-4. It's a well developed unit that actually could stretch far beyond the grade K-4 parameter.

The second unit explored suffered a bit from too much time spent on the first, but was still a welcome exercise. Study Activities for Harry Potter and the Half-Blood Prince reminded me of the many novel groups we used to teach in sixth grade where we replaced the basal reader with high interest, level appropriate novels for our kids. We spent hours preparing our units. Such activities on TeachersFirst could be a real time saver for teachers. The Harry Potter unit appears to be a good one.

One can get lost in this site and occasionally frustrated finding things. After the Harry Potter study guide, I searched for similar study guides, but the listing was all over the place. A page of study guides for novels would be helpful.

The site includes a weekly Featured Sites page, Resources by Subject & Grade, and a delightful Question of the Week for teacher discussion. From the Question Archives, I pulled up the question, "Many strategies are being discussed to improve student achievement and/or balance budgets. Would you be willing to teach larger classes (35-40+) for higher pay? Why or why not?" The responses are something our President and SecEd should read before they continue suggesting that larger class sizes are a viable option for America's classrooms.

TeachersFirst isn't one of those "pretty sites" that have spent a ton of time and money on page design at the expense of content. I was overwhelmed with all of the good, free resources there. I've left out lots, but I've got to sneak in their Tools to Use "In the Trenches" listing. It's practical stuff that can make your day (or school year).

Teachers First has revamped their site since my original review of it. Some of the links above are to their legacy site.

BTW: The same writer who did the resources piece has published another for mobile devices, Ten of the best Droid apps for education. It's another good attempt at an idea, but any top ten that focuses two of its top ten on student gradebooks, which most teachers already have to use via their schools' required use SIS software, is pretty lame.

A Good Video Resource Site

WatchKnow.orgAs I worked through all the sites recommended in the comments to Jenna Zwang's Ten great sites with free teacher resources towards the end of March, I was repeatedly disappointed to find that many of the sites suggested were merely come-ons for commercial sites. One truly free site that had lots of recommendations is WatchKnow, a site dedicated to organizing in "one, super directory the hundreds of thousands of good videos currently available on the Internet." All videos are reviewed for appropriate content before being categorized using a wiki framework and philosophy. "The videos...cover all major educational topics from elementary to secondary schools (or age range 1 – 18), and are Kid Safe!"

Click, Clack, Moo, Cows That TypeI sampled several of the videos, including the delightful Click, Clack, Moo, Cows That Type- In American Sign Language. As an ex-farmer, I wondered how the cows could go without milking, but it's fantasy. Right? A favorite from the old Electric Company, the Silent E Song (Who can Turn a can into a Cane?), brought back pleasant memories of my classroom teaching days.

Some videos, such as NOVA's The Embryo Takes Shape, take the viewer off site (which could present a problem with school filtering software). And others like The Stages of Mitosis were choppy because our home satellite connection was just too slow to handle them. One, the Helping Verb Song, which I really wanted to see, simply wouldn't play due to our slow connection.

The cataloging and organization of the site is excellent, if a bit unusual at times. When I looked for American History, I found what I was looking for under History of the United States. Declaration of Independence - Remember this includes quotes from Thomas Jefferson followed by present and former NFL players reciting the Declaration.

The commenter to the article wrote, "WatchKnow.org has over 23,000 free, educational videos vetted by teachers for teachers in a super-convenient and intuitive directory covering every topic imaginable." I've got to agree.

Science Fair Intro

March generally isn't the time of year you'd introduce a science fair to your students, but I'll definitely forget this resource if I don't put it in print right now!

A Chris Dawson posting on his ZDNet blog, Oh, that's how you do a science fair project, led me to Prepare for the Science Fair on YouTube. The fifteen minute animated video by Kevin Temmer, a high school student in Florida, is designed for use with middle school students. It pretty well covers the basics of doing a good science fair project. Chris also did an interesting email interview with the creator of the video.

Memidex

A press release in March reminded me of a site I first covered in our The Freewares of 2009 feature story. Since publication of that story, the free Memidex online dictionary and thesaurus has grown up quite a bit. Memidex still uses its own definition derived from the WordNet database developed by Princeton University, but now adds definitions from lots of other sources. They also offer some tools which might be helpful for some users, and thankfully, provide audio pronunciations for those of us who haven't fully memorized a pronunciation key.

Note: I find myself using Memidex more and more. I like its listing of multiple definitions and sites.

Something a Bit Different

The Khan Academy is a not-for-profit site that provides free ten minute video lessons and exercises "especially purposed for viewing on the computer." This unique site covers "K-12 math, science topics such as biology, chemistry, and physics, and even reaches into the humanities with playlists on finance and history."

Khan AcademyThe intro video at left relates that Sal Khan got into creating educational materials while tutoring his nephews. Part of the video shows the graphic at right, which relates that Sal is the author of all the materials on the site!

One of the things I really liked about Khan Academy lessons is that the videos are really sharp, but still optimized so as not to be choppy on a slow internet connection. I even loaded some other web pages while viewing several lessons to try to make them choppy, but found most of the lessons played smoothly, even under a slow or crowded connection.

Login at Khan Academy requires either a Google or Facebook account and password. Students log in and may select a "coach" that can be a parent, tutor, or even their teacher (if they've set up an account). Teachers can see stats of student progress on the site as well. Since all the lessons I sampled were YouTube videos, teachers also have the option of embedding the YouTube video in online lessons of their own creation on their web site or a Blackboard or Moodle site.

I didn't test the teacher stat features, however, as I'm pretty guarded with my usernames and passwords.

For balance, you might want to look at Mike Doyle's evaluation of the Khan Academy in his No Khan Do posting.
