The “Idea Wall” – Installing A Whiteboard Wall – On The Cheap.

Crossposted from my EdTechTeam Teacher Leader Portfolio.

As a part of the EdTechTeam Teacher Leader course we had to look at redesigning our learning space to make it more conducive to meeting our students’ needs. We looked at seating, arrangement and choice of furniture, and how we used our wall space.

I decided to use one of my walls to put up a 5.5ft wide, 8ft tall whiteboard. When I ran the idea by my principal he immediately dubbed it an “Idea Wall”. I installed it for about $45

On a lark I decided to also extend my whiteboard at the front of my room to the ceiling so that I could use it as a giant screen. This added a third sheet of panel board to my project and increased the cost to about $60 total.

Be Careful What You Click On — Man-in-the-middle attacks disguised as Twitter “branding”.

This is something that we educators need to teach our students as a part of Digital Citizenship.

A disturbing trend on Twitter.

In the last several weeks I have become aware of an insidious, disturbing “service” called Linkis. Linkis.com man-in-the-middle attacks your browsing to inject their content into your stream. This violates your privacy allowing Linkis to track your browsing and modify what you see on pages  you visit.

Wikipedia describes man-in-the-middle attacks:

 “In cryptography and computer security, a man-in-the-middle attack (often abbreviated to MITM, MitM, MIM, MiM attack or MITMA) is an attack where the attacker secretly relays and possibly alters the communication between two parties who believe they are directly communicating with each other.”

When contacting the people who have been using this “service” I found a disturbing trend, none of them knew that they were using it. That is right they had a service linked to their Twitter account (and possibly Tumblr) that was changing their posts without their knowledge.

How does this happen?

Linkis spreads like a virus. One person gets it but doesn’t notice the symptom of the changed link in their post. After all, with Twitter using link shortening sometimes the link changes for a valid reason. Then another unsuspecting person opens the link and when it opens it looks exactly like what they expected to find except for the URL and a box on the side of the webpage.linkis callout.png

 

Linkis then pops up a window that looks like this that can make you think that you need to click it to see the content you planned to view. If you click connect then it links to your Twitter account and you have caught the Linkis bug.

Once you have caught the Linkis bug then when you post a link in your tweets Linkis will replace the links in your tweets with their link. Anyone that clicks this link goes to Linkis’ site instead of the place you intended to send them and is vulnerable to accidentally adding Linkis to their account.

I figured out that I caught the Linkis bug, how do I fix it?

In order to stop Linkis you have to go into your Twitter, Tumblr, and other sites to deauthorize their access to your account. I also recommend that you report them to Twitter. The gif below shows how to do it and here are links to how-to videos on my YouTube channel. Remove Linkis from Twitter and Tumblr. Edit: 7/13/16 Videos embedded at the end of the post.

Remove Linkis

Please share this with everyone you know so that we can block Linkis from spreading. You might also think about contacting or tweeting to the Electronic Freedom Foundation (@eff) about Linkis and its man-in-the-middle attacks. The EFF is an organization that champions people’s privacy and security on the internet.

#GAFE4littles Archived

Shortly after I started my new Twitter handle for education (@mcarlingoldberg) I ran across Christine Pinto’s feed (@PintoBeanz11) she is an educator who teaches Transitional Kindergarten (TK) and is successfully using Google Apps For Education (GAFE) with her students. I have found my interactions with her to be very awesome and the resources that are starting to be shared around #GAFE4littles, the hashtag she started, are going to be very useful to primary teachers.

In order to save all of that wonderful information in a usable format I started archiving the #GAFE4littles hashtag as of today.

A searchable archive of the tweets can be found here: https://bit.ly/GAFE4littlesArchive

Please share this resource with all of your colleagues who teach primary grades they will get a lot from what everyone is sharing.

Unfortunately I wasn’t able to archive the tweets prior to 6/12/16. If you know how to archive older tweets containing a specific hashtag, please let me know, I would love to get everything.

UPDATED 6/21/2016:I forgot to include Christine’s site. Tech With Pinto.
Also, I managed to use Twitter advanced search to find all of the old tweets and Snagit to get a picture of it. Still looking for a way to pull the actual tweets to make them searchable.

(Crosspost) Digital Citizenship – Strong, Memorable Passwords

(Crossposted from my EdTechTeam Teacher Leader Certificate Portfolio  https://mcarlingoldbergtlcportfolio.wordpress.com)

It is 2016, as educators it is no longer enough to teach our kids how to keep themselves safe on the streets because so much of all of our lives takes place on the internet. Internet safety is one aspect of Digital Citizenship in which we must make sure that our students and children are fully fluent. One aspect of internet safety that I think is incredibly important for everyone, child or adult, to get behind and understand is the need for strong, memorable passwords.

Strong, memorable passwords that are unique to every situation are an absolute necessity in today’s world. Having weak passwords, especially if you reuse them in different places, is like asking someone to steal your identity, your money, even your safety as they get access to all of your personal data and accounts online.

Generally, most people do passwords very badly. Even those who actually try to have good passwords. One aspect of this is illustrated by the XKCD comic.

First Post – Mirrors: Self-reflection and communication.

As of today this blog has existed more than six weeks, with no posts, and no title. This morning I found both snuggled up together. Please read to the end to find out where I found them.


Two months ago I had an experience that opened my eyes and changed my teaching forever. What was this experience? I attended my first (but not my last!) Google Apps For Education Summit (GAFE). It was hosted by EdTechTeam at Windsor High School on April 9-10, 2016. I am super excited about attending the next Sonoma Summit in October.

Why did the GAFE summit have such an effect on me?

There were two reasons. The first was all of the incredibly awesome information, resources, and connections that I made at the summit. It revitalized my teaching mid year and reenergized me enough that Monday, though I was tired, several people mentioned that I seemed much more upbeat. That high energy boost lasted all the way through the end of the school year.

The second and probably more far reaching reason can be summed up in one word. Twitter.

I have been on Twitter since the beginning of 2008. I followed the same people that many Twitter users follow. My personal friends, actors, celebrities, athletes, a couple of politicians, the President of the United States (@POTUS), etc. My feed was closed and it even updated my Facebook profile so I didn’t have to go to FB if I didn’t want to.

How did Twitter change me at the summit? I noticed that every single presenter had their name and their Twitter handle on their presentation. Not their email address. The GAFE Summit organizers encouraged us to tweet about what we saw and what we learned at the summit using the #GAFEsummit hashtag and to share it with the @edtechteam Twitter account. This is when I discovered Twitter as a Professional Development (PD) model.
