Good Passwords

Internet Security
Internet Security

A good reminder about passwords is important from time to time:

1) Passwords should be six characters or longer.

2) Incorporate random capital letters, swaps letters for numbers (like vanity license plates) and includes a symbol or two. The password “password” (which you should not use) is much stronger as “r1Va’5paZZw8rD.”

3) Don’t use names of pets, children or streets. It’s better to use a phrase, song lyric or line from a poem as the base. “Hey Jude, don’t make it bad” could become “d9n’Tmak%6aad.” Base the password on the first letter of each word, turning the lyric into “HJ,dmi6.”

For more, read Microsoft’s advice.

For those of you with Macs, get 1password, it is a program that saves all your passwords and backs them up.  That way, you will never forget a password.

To make things easier, use the same username for everything.

And the security wonks aren’t going to like the next thing I’m going to say:  Here’s the main thing.  If what you are doing isn’t about money, use the same password for everything.  It’s not worth trying to remember.

But with 1password you don’t have to.  I use an independently generated 26 alfa-numeric  password for everything.  1password is a beautiful thing.

25 Digital Things All Teachers Should Know – Updated

25 Digital Things all Teachers should knowThanks to those folks who sent in suggestions on improving this list. Your comments are welcome.

1) Mozilla Firefox is a “nondenominational” web browser.  Microsoft‘s Internet Explorer browser pushes users toward Microsoft products.  Google Chrome browser pushes users toward Google products.  Apple’s Safari browser is very light on features when used on a windows machine, but pushes people toward Apple when used on an iPhone and mac.  Mozilla Firefox is superior to all in that it does not push users toward specific products and is feature rich.

2) Delicious Social Bookmarking is the best way to manage website links.  This links to a page which explains social bookmarking, How to Social Bookmark.  Social Bookmarking has fallen out of favor for possibly two reasons.  First, nobody could find a way to monetize it so sponsorship is really not available.  Second, folks are just not storing bookmarks to specific pages as they once did.

3) Blogs are Internet resources which are great for publishing and managing student work.  This links to a page which explains blogs, What’s a Blog.

4) Wikis are Internet resources which allow multiple users to edit documents, make lists, and coordinate information.  This links to a page which explains wikis, What’s a Wiki.

5) Twitter is a “micro blogging” site. It is one of the best ways for teaching teams to maintain instant and ongoing communication throughout a busy day.  Twitter has the benefits of instant messaging, while maintaining a record of what is communicated so the information can be read whenever a team member has a free moment.  Here’s a short video explaining twitter.

6) Tagging is the new way of organizing digital items online.  Tagging is a way of putting multiple lables on items such as documents, photos, audio files, etc.  One can then pull similarly tagged items.  The truly interesting thing is in most online environments tags are not centrally organized.  Users choose which labels they place on digital objects.  The distributed nature of this organizing tool creates a more social form of organizing large amounts of data.  This links to a page which explains tagging, Wikipedia on Tagging.

7) Snagit is a product which can be purchased and downloaded to a user’s computer. SnagIt is a screenshot program that operates under the Windows operating system contains most features needed (scrolling page screenshots and automatic ‘trim edges’ function, for example). SnagIt Accessories extends its features. For example, Flickr Output enables the user to upload screen capture onto one’s own Flickr account. The ease of use, comprehensive features makes it one of the best cut and paste software packages available.

8) Flickr.com online photo storage allows photos to be shared and organized with tags.  One can also search thousands of copyright free photos organized by tags.  Here’s a link to a page that explains social photosharing.   Here’s a link to the flickr site for the National Zoo, www.flickr.com/nationalzoo. Two other important source of photos are Wikimedia Commons and the Morguefile.

9) Audacity is a free program that allows anyone to easily make digital audio recordings.  Digital recordings can be rendered in MP3 files (like what are used on iPods).  Any digital recording can be called a “podcast” even if it is only stored on a computer or website.  Here’s a short video explaining podcasting.

10) PhotoStory3 is a free program that allows anyone to easily make a presentation out of digital photographs.  PhotoStory3 allows users to add titles, narration, background music and different focusing and other effects on the photos and transitions between the photos.  Digital photo stories can be rendered as windows media video.  A wmv digital video file can be posted on a website, inserted in a blog, wiki and/or PowerPoint.

11) Photos can be edited with any number of photo editors.  There are rudimentary photo editors within free resources such as Flickr.com, PhotoStory3 and commercial software packages for photo editing such as Adobe Photoshop, Adobe Photoshop Elements and even in some children’s educational software such as Imageblender.  There are also some free online options including Picnik (http://www.picnik.com) and Photoshop Express (http://www.photoshop.com/).

12) Windows Movie Maker is a video creating/editing software included in Microsoft Windows. It contains features such as effects, transitions, titles/credits, audio track, timeline narration, and Auto Movie.

13) Learn360.com is a subscription service which has a)full videos, b)video segments, c)high quality still photos, d)audio clips and other media elements organized by key word and grade level.

14) Gcast.com is a free Internet site for creating and posting podcasts.  Podcasts posted on Gcast can be linked to from any web resources (blog, wiki, etc.) and reviewed multiple times from any computer or handheld device with an internet connection.

15) Youtube.com has many useful and educational video resources.  They are searchable via keyword.

16) Teachertube.com is an educational resource of videos modeled on youtube but subject specific to education.

17) iTunes is a free product which one can download onto their desktop.  It allows digital audio files to be organized and shared with others.  Audio files stored on Gcast.com can be lists on iTunes for any iTunes subscriber to download and play on their computers, iPods and/or telephones.  iTunes begins to cost users money when they purchase items from the iTunes store.

18) RSS feeds can be found on almost all websites, blogs, wikis, photo sites, and other resources on the web.  Users can subscribe to the RSS feeds for Internet resources they wish to regularly track.  Updates to those internet resources are sent to the subscribers via the RSS feeds and organized in what are called RSS Readers.

19) Google.com has many features besides gmail, the search engine, and Google Classroom.

20) Internet safety focuses on four main concerns: 1) Internet bullying, 2) Internet predators, 3) Internet identity theft and 4) Internet negative identity profiles impacting college entry and career opportunities.  All four of these aspects of Internet safety can be covered with two safety principles.  The first is to keep one’s personal information secret.  This includes name, contact information, work and school information, family information and the names of associates.  The second is to never meet anyone in real life, who one has only met on the Internet.  With these two principles, students (and teachers) can protect themselves from the major Internet safety concerns.

21) Publishing on the Internet can be done professionally while maintaining the safety of students and colleagues by following APA publishing guidelines.  By combining the APA ethical guidelines (no student identifiers, no school identifiers) with the Internet safety principles of keeping the author’s identity secret, a great deal of professional practice can be shared in an online professional learning community without fear of breaching our professional ethics.  You can review APA Ethic’s Code here.  Clairvoy is dedicated to teachers publishing strategy.  See more here.

22) Students with different learning styles (visual learners, audio learners, etc.) can better explore Blooms Taxonomy of cognitive objectives by working with the curriculum using the different media available to them in a digital environment.

23) Copyright is important and must be respected at all times.  The copyright laws regarding special education do allow for materials being used in class (which have been purchased) to be adapted to meet the needs of student IEPs.  This can call for teachers to use all the digital tools at their disposal to adapt standard text, photographic and multimedia resources to meet the needs of student IEPs.  Anyone can do this adaptation for the teacher’s needs, including students inside and outside the classroom.  Here are a number of online resources on use of copyright in the classroom.

24) Evernote allows you to easily capture information in any environment using whatever device or platform you find most convenient, and makes this information accessible and searchable at any time, from anywhere.

25) Google Earth is a tremendous tool. Hardware such as Flip video cameras (under $100), student digital still cameras, color scanners, document cameras, transferring video from camcorders to computers (Firewire pcmcia card cost around $20  / some analogue to digital video converters cost less than $50), SMARTBoards and iPods are all things with which teachers should familiarize themselves and use in their teaching.

Inserting The Editorial Process into Clairvoy

Teachers trading strategy and the writing process.
Where We Came From:

Clairvoy (now Traditional Clairvoy) started out as a blog with five teachers giving advise to other teachers who submitted questions.  We still get messages from teachers all over the world. We’ve grown to a site with blogs, wikis, forums, articles and file sharing.  More than 1000 pages of different content and nearly 800 registered users.  We have a new site for teacher research called Education Study Group.  However, most of our visitors don’t sign in. People just read.

On commercial sites like YouTube and Wikipedia, less than 3% of users post content.  A much larger percentage (but much smaller number, of course) of our users contribute content.

For instance, as I write this 75 people are visiting Clairvoy (much the same as any time of day-even at 3am!). I can’t see who you are or what you’re doing (which drives me crazy) because most folks don’t login. Most just read.  But you all seem to be getting some benefit, and that’s great.

We’ve been focused from day one on the content, “Teachers Trading Strategy in Bite Sized Pieces” and that’s not changing.  But since we started (at a time when “what?” was the only response we ever got to a sentence containing the words ‘blog’ or ‘wiki’) we also functioned by default as a “sandbox” mashup of all the available technologies for teachers to learn how to use these new web2.0 thingamajigs.  Things have grown up around us.  With the right safety training, Wikispaces is great for teachers and students as are Google Sites, Blogger, and WordPress.com.  You all know more today than you did just a few years ago.  Even Twitter is now a household word.

Where We Are Going:

We are staying focused on trading educational strategy, The “what we do” and “our values” pages will not change.  Our strategy is to better harness contributions of our users and create more meaningful and useful content. As a result, we have made some improvements to Clairvoy which will be steps toward the goal of better serving your needs:

One: The first step is an improvement to the search function with Advanced Clairvoy Search.  It’s up in the right hand corner.  It’s simply Google’s engine focused and targeting Clairvoy’s sites, blogs and features. (I’ve never said we’re creating a new wheel here folks.)  There’s an even more advanced targeted and detailed search available on the main menu under “Search.”

Two: The second step is a stronger editorial process on the wiki.  Everyone will still be able to contribute. This feature has been implemented.  The details of how that works are below.

Three: The third step is we have introduced an “Articles” feature for documents and reviews of scholarly articles. These differ from wiki pages in that they will not be changing.  It is a process for educators to provide peer reviewed information in longer format. As well as to collect reviews of scholarly papers which could help educators. This feature has been implemented.

Four: The forth step will be making the Clairvoy Blogs more robust.  We have recently employed the same technology used by WordPress.com.  Over the coming months we will be adding all the features and functionality available.

The Editorial Process:

I wrote recently about the Writing Process and Open Collaborative Internet Tools.

MOZILLA, the folks behind Firefox browsers, use the same open source technology Clairvoy uses for their wiki: see http://support.mozilla.com.  Mozilla developed an easy to use editorial system which we are going to employ.  Any wiki page created or edited is not displayed to the public until it is looked over first.  The original page remains viewable until the updated version is approved and it is replaced.

If you login, you can see all the “sausage being made” with all the immediacy as always but with better labeling.  If you are not logged-in, you only see the finished product.  This simply will make a “drafting” area (for those logged-in) where contributions are welcome, but at the same time have the “published” knowledge base (for those not logged-in) that is extremely stable.  The difference being a day or two and, we hope, greater quality and better organized content.

We’re going to give it a try.  It means the pages you contribute to our wiki will be delayed for users not logged-in.

This new editorial process is just for wiki pages, not individual Clairvoy Blogs which have secondary logins for their owners to control more of the features within their own blogs.

Our values will not change and contributors who are unsure of the technology but have something to say will be helped through the process – not flamed.  That has been the case and will not change.

Contact Us:

The “Contact Us” function works now if you logged-in or not. We’ll try and be responsive to you (our readers and contributors) as we try to grow what we are doing to best serve you.  Let us know what  you think.

Best Tracking of Student Data (for Behavior Plans or Anything) for the Busy Teacher

Graphic of Google forms for data collection
Graphic of Google forms for data collection

This is a way to use Google Docs and an iPhone or any hand-held device that can hit the web to track student data.

Remember in Educational Research, APA ethical guidelines require no information be used which could be employed to identify the student.

1)In Google docs, open a new Spreadsheet.

2)Name columns with the items you are tracking; Disrupting Teacher; Disrupting Students; Absence of Bad Behavior for 30 minutes, for example.  This will be determined by the student’s Behavior Intervention Plan or whatever research question you are tracking.  Each entry you make will automatically be stamped with the time and date, so you don’t have to worry about that column.

3)On the “Form” menu of the same spreadsheet click on “Create form.”  Name the form something you can remember, but not the name of the student.  Then on the Form menu choose “Go to live form” which opens your form as a webpage.  Along the bottom of that window is the “You can view the published form here: url” which is the web address of your live form.  Make a shortcut to the live form and put that on your iPhone or whatever you want to use to enter data.

From that point on, everything you enter into the live form and save, will be entered into your spreadsheet as a row and saved for your later analysis.

On the way out, remember to Save your form, and choose File and Save your spreadsheet.Too Easy!

For extra credit, on the forms creation page, you can edit the questions and make them multiple choice or check boxes to make data entry even easier!

On Illustrating Life-Long Learning

To be a life long learner is a wonderful thing, to be shared.There is always time to show our students we are life-long learners and they should be as well.  It is a fundamental part of running a constructionist classroom.


“I didn’t learn until just now, simile is called a simile because it is “similar.”

from a second grade teacher shared with her class.


“It wasn’t till my 30s that I realized the “arbitrary” division symbol showed two dots DIVIDED by a line.”
