TechTalk4Teachers - Security Questions and Holiday Tech Gift Ideas

12/16/2013

Episode 160 – TechTalk4Teachers Podcast

In this Holiday edition of the TechTalk4Teachers podcast we discuss the need to choose security questions wisely so that only you know the answer. Just like passwords, security questions also need to be guarded with care to protect yourself (and others) from unwanted account compromises.


In our Technology Picks of the Week segment the TechTalk4Teachers crew will share some stocking stuffer ideas that range from customized personal gifts to an affordable educational computer science project for those wanting to learn more about computing.

Creating a 3D Bulletin Board with some Holiday Cheer

Creating a 3D Bulletin Board with some Holiday Cheer

12/11/2013

I recently had a couple of my graduate assistants refresh the bulletin board in the ITC. We try to do this at least monthly to give visitors to the ITC ideas for their classrooms. I always stress to our pre-service teachers that bulletin boards are an effective communication tool and you should not limit bulletin board designs to two dimensions. Since it is winter time we had the idea of making a Snowman scene with 3D snowflakes hanging from the ceiling to make it look like it was snowing. 

Learning is an attitude and having a pleasant learning environment is an important component for making students feel welcome in their learning space. Bulletin Boards provide information but they also can help set the atmosphere for learning. How welcoming is your classroom? 


Here is their accounting of how they did it.

Katy and I work here in the ITC and one of our tasks is to create bulletin boards for others to learn from.  This month we wanted to do a Holiday board because we are entering winter break.  First, we searched ideas through Pinterest.  I don’t know if many of you have an account, and I am sure you do not need one to look through photos.  However, Pinterest is a great source for educational ideas.  Once we narrowed our search down to the picture we wanted, we got to work. 

The ITC has a lot of great supplies to help create the perfect bulletin board from die-cutters, to backdrop paper, markers and construction paper.  We measured out our bulletin board and got the appropriate amount of backdrop paper to get started.  Once you have that positioned the rest is a breeze.  Katy worked with the die-cutters in cutting out many snowflakes.

If you have not already been in to the ITC, come in and take a quick look around.  The die-cutters are a great source for cutting out letters and different shapes and pictures.  Once the snowflakes were cut out, Katy took two at a time, folded them at 90* and taped two together to form a 3-D illusion of a snowflake.  While she was working hard on that, I cut off some white paper and began working on the snowman.  I personally think it looks best whenever it is freehand because it makes it look more authentic. 


For this particular bulletin board, we wanted the snowman to look like he was sticking out off the bulletin board, having a little extra paper on the sides to make that possible helps.
  Katy took another yard of white paper and began working on the “snow slopes” that would be in the background of the bulletin board.  Once again, I think it is best if you try to freehand this.  Just cut out a flowing landscape, it doesn’t have to be perfect! 

Once you have the snowflakes, snow slope, and snowman cut out you can begin putting it together using a layered approach.  First we stapled up the snow slopes in the background.  Once that was done, Katy got to work stapling the snowflakes on the backdrop like they were falling.  Next, we began putting the snowman up.  We wanted to have him look like he was a 3-D figure. We stapled the bottom first and somewhat up the sides to leave some room in the middle.  Once that was done I took the left over paper that we used and crumpled it up into balls of paper.  We took that and stuffed it in the snowman’s belly to make him “pop” out.  Katy picked out a green boarder to go around the outside of our bulletin board to hide any of the messy side parts and to make it look like a wintery scene.  We took left over construction paper and began making the buttons that go down the snowman’s outfit, and the coal shapes for the eyes, and mouth.  Katy made a nose out of left over construction paper.  If you try this yourself, maybe making the nose look like it is sticking out, to make it 3-D would be a nice effect. 

Katy got busy working on the snowman’s top hat; once again, we freehanded all of this to make it look fun and artsy.  After that, Katy created from left over construction paper the berries on the hat and the leaf.  I used the letter die-cutters to spell out “Happy Holidays From The ITC” as a festive touch. 

The die-cutters in the ITC are a lot of fun to work with.  They’re simple and make any project easier and more enjoyable.  We took brown construction paper to make the arms of the snowman by cutting it in half, width-wise.  Then we took each half and twisted it to give it a “stick” look and stuck them into the sides of the snowman. 

Katy found little light bulb shapes die-cutters and made a bunch in assorted colors to put along the outside of the bulletin board.  It added some flare in making it look more festive! Then we took a permanent marker and traced the light bulbs as if they were on a string of lights.   Once all of that was put together, I took fishing line and a hole-punch and went to work on the left over 3-D snowflakes we had.  I punched a single hole in the tops of the snowflakes, then I snaked through some fishing line just enough on each to make them look like they were falling at different lengths.  Tie the end of the fishing line to a paper clip and then attach to the ceiling tile tracks above to hang the snowflakes. 

As a final touch we cut out a small pocket shaped piece of paper and taped it to the Snowman’s chest  that served as a pocket to hold a MP3 Player that we cutout and colored with a highlighter. We used real headphones and made it look like they were connected to the MP3 Player in his pocket. 


If you look closely the Snowman is listening to our TechTalk4Teachers podcast!

Organizing Files, Folders, and Backups – Tips & Tricks

Organizing Files, Folders, and Backups – Tips & Tricks

12/10/2013

Face it, we are all busy, wasting time trying to find that one file can be extremely frustrating.

Some say they are too busy to make regular backups of their files… that is until something goes wrong. If you regularly use a computer/device then you need to have an organizational strategy that makes things easy to find as well as having a backup/restore procedure for those “just in case” moments. This is one of those areas where an ounce of prevention is worth a pound of cure.

I recently completed a two part screencast about organizing files, folders, and backups and posted to the ITC Techshare YouTube Channel. In Episode 33 and 34 of ITC Techshare I explain how I organize my computer files by academic year and subfolders.


As an educator, filing things by academic year makes sense to me. If you are an accountant or in administration, maybe organizing by fiscal year will make more sense to you. Most importantly use a system that works for you. The electronic filing system structure that I use has worked very well for me over the years and has several benefits.

1)    Files are organized by academic year so they are easy to file and find. Having a file structure that works for you will make you much more efficient and productive. Even with the ability of most operating systems to quickly search a hard drive having a structure will save you from wasting valuable time looking for files.
2)    Files are easily archived from previous years, once an academic year is over you can make a complete backup for archival purposes. These files should not change as the year is over and this archive represents a snapshot in time. You will need to make a backup of all your archived folders and have them ready to restore if needed.
3)   Because older academic years are archived in their own separate folder you can concentrate your efforts on routinely backing up the current academic year files that routinely change. These represent your active work that may change daily. Since you have already archived previous academic years work on other backups you can concentrate backing up the much smaller and constantly changing current academic year folder.
4)    Remember, in the event of a computing/natural disaster you are only as good as your last backup that you have access to. You will need your last backup of archived files as well as your last backup of your current academic year files readily available if a disaster strikes, see the 3-2-1 Backup Rule below.
5)    It is not enough to just backup your files, you must also have confidence that you will be able to restore your files from a backup, if needed, in the event of a disaster. You will want to periodically test your recovery procedures to make sure your system will work in the time of need. Check with your IT department for assistance.

In Part 1 of this screencast I share the basic file structure I use to organize my files.



In Part 2 I share some backup strategies as well as the 3-2-1 Backup Rule that will maximize the protection of your data in the event of a disaster.




When should I backup my files?

I use the “Pain Theory” of backups. If it will be painful to re-create the work that I may potentially lose due to a computing failure then it is time to make a backup. Anytime I have done a lot of work that I do not want to lose... I make a backup. At a minimum the beginning, middle, and end of the semester are good times to make a backup as these are times of massive changes. Of course, I do this more often as necessary. Each backup is a snapshot in time, so as changes occur you need to regularly make backups. 

If you use a network drive your IT department may already make regular backups for you depending upon space limitations, many IT departments enforce quotas for network drives so be sure to understand what is and is not being backed up.


3-2-1 Backup Rule

In Episode 34 I briefly explain the 3-2-1 Backup Rule that states you need to have:

§         3 copies of anything you care about
§         2 different formats
§         1 off-site backup

I have also provided a link to the full blog posting by Scott Hanselman about the Computer Backup Rule of Three that is worth a read at:


Be sure to follow your organizations policies about making and storing backups. Just like your computer access, backups need to be stored in a safe and secure location behind locked doors. Also, be aware some organizations may not approve of “cloud storage” services like Dropbox, SkyDrive, Google Drive, iCloud, etc…

Cloud services have varying degrees of security and you should not store private/confidential information to personal accounts using cloud services that are not supported by your organizations IT department policies and procedures. These policies and procedures are put in place to protect data and confidentiality. Each organization will need to develop its own policies and procedures when it comes to using new devices and services. These services are evolving rapidly so a regular review will be necessary to keep up with the changing technologies.

Great for Students Too!

We are starting a new semester in January and it would be a great time to do some preemptive organizing for a new semester. If you are a student, imagine if you were to organize all of your courses by academic year, each in their own subfolder. At the end of your four years in college you would have a well-organized conglomeration of everything you did in college by course, by academic year. This will help in your future job search as you can refer back to examples of coursework you completed and makes it easy to put together a portfolio of your finest work.

Best of all, you will be able to find it!
