Displaying Tweets Real-time with PowerPoint Presentation: With or Without Moderation

Recently, our organization decided to implement real-time tweet displaying along with our PowerPoint based Base Camp and Leadership Summit training. We will be displaying the tweets at the training site on the big screens. Therefore, I investigated eight different tweet displaying services to determine what is the best option to do it.

My first intuition was to embed tweets directly inside of the PowerPoint presentations. Simply by Googling, I found the highest ranked tutorial for doing so by Liz Gross at her blogsite. Following her instruction, I tested out all the Tweet-displaying services listed in her post, plus three more: Twubs, TweetWall, Tweet Chat, and Hootfeed. I use the PowerPoint 2013 Pro. My testing result shows that among the eight choices, only three of them were able to be correctly displayed within the PowerPoint, which are: TwitterBeam, Hootfeed, and TweetFall. All the others show error messages such as “script error” or “Jason not defined”.

Since for PowerPoint 2013 users, in addition to the steps mentioned by Liz’ blog post, it took extra `steps for me to set up the tweet webpages so that they will display in the PowerPoint. I wonder whether this is the reason why more than half of the tweet services were able to correctly display within the PowerPoint. So I think it is worth to sharing the process for others to learn from.

First of all, the download link for the free LiveWeb Add-in is missing from the How-to Geek tutorial. It is easy to find, but just in case, you can go here: http://skp.mvps.org/liveweb.htm#.VEASLfldV8E

Second, for PowerPoint 2013, you will have to manually change the registry subkey for each computer that your PowerPoint would display the embedded Tweet feeds from. To do this, follow the instruction here.

Third, remember to save your PowerPoint as “.pptm” format (PowerPoint Macro-Enabled Presentation).

After doing all the above, only one commercial service and two free services fully support displaying Tweet feeds inside of Powerpoint (at least it is the situation for Powerpoint 2010 and PowerPoint 2013). They are:

TwitterBeam:

Hootfeed:

and TweetFall:

TweetFall claims not officially supporting PowerPoint embedding. However, their first layout design would work when embedded with PowerPoint, and their price is good:

Below is a table comparing the main features of these tweet displaying services:

Tweet Displaying service	Moderation	Pricing	Embed in PowerPoint	Adding Company logo
TwitterBeam	Yes	Contact them for price	Yes	Yes
TweetWall	Yes	$58 per day	only the first layout works	Yes
Twubs	Yes	$99 per month	No	Yes
TweetFall	No	Free	Yes	No
HootFeed	No	Free	Yes	Yes
TweetWally	No	Free	No	No
Visible Tweets	No	Free	No	No
Tweet Chat	No	Free	No	No

So after all these experimenting, we have decided to go with TweetFall using its first layout design.

ebook vs. web app

The SLIDER project I currently work on may want to publish their curriculum as an “eBOOK”. However, what my customer wants seem more than just a regular eBook like those you see on kindle or nook.
What is the difference between a traditional ebook (published with epub 3 etc.) and a web app? Shouldn’t that be much easier to just wrap a html(5) based website and publish it as an app then use it as an eBook? I decide to do some digging.
An interesting article read about it is: http://toc.oreilly.com/2012/10/ebooks-as-native-apps-vs-web-apps.html
More results will be reported and discussed here later.

Adding Open Badges to Your Moodle Course – Step 1: Install Moodle 2.5+

Picture retrieved from http://openmatt.org/2011/09/22/whats-your-elevator-pitch-for-badges/

Open Badges and their use for online informal or formal learning have been explored for a while. But it is not easy to hand-bake a badge and issue it manually. I tried to manually create one based on the instruction here: Open Badges: Want to Make Your Own Badges by Hand? Here’s How., but this post doesn’t include the process of Badge issuing and sharing. In general, to issue a Badge to certain learners with the set up of the criteria process of gaining a badge requires quite amount of coding, which is not an easy path. So, it is great news when I found out that Moodle finally released their newest version of Moodle 2.5 as of April 5th, 2013, and that includes the Open Badges function!

So here is the recorded process and tips during the installation of Moodle 2.5 and trying out the Badges function on my GoDaddy server:

Step 1: Download and Upload the Moodle Package

First of all, as of July 25th 2013, GoDaddy does not provide the latest version of Moodle installation. The version they have available right of this time is version 1.9.1. After finding out this, I had to remove the installed moodle and manually downloaded the version 2.5 pack from moodle.org.

Note: as of August 1st 2013, when I checked the latest stable version of Moodle package for download, there was a newer version of Moodle 2.5.1 which was made available right after I originally published this blog post. Oh well, this is technology, so we should not be surprised.

Step 2: Create a MySQL database for your moodle site

The next step was to create a MySQL database on your server. Moodle 2.5 requires the MySQL version of 5.5, so be aware of this. I named my database “moodlebadges”.

Step 3: configure your config.php file

After downloading and uploading the package to my server, I started to install it via the website interface. That was when I realized that this version 2.5 does not have the config.php file, which was vital for the installation. Hence I went back to the version 1.9.1 and copied a config.php file and then pasted it into the 2.5 folder.

The next step was to make sure everything inside of that config.php file is correct in terms of your Moodle database connection. This included setting up your database log info, and paths such as your dirroot, dirdoc correctly.

Step 4: Install your moodle site

And now if everything has been set up correctly, you should be able to go to your moodle web address and start installing with the web interface. For my moodle site, the address is blog.tech4teaching.net/moodle

You will first see a screen asking you to choose the language like this (or it could be slightly different depends on your Moodle version):

The next screen is something like this:

Then you will just have to follow the instructions on the screen and finish your installation.

At last, you will see a screen with the Navigation bar and Administration bar on the left, something like this:

Click to expand “Site Administration”, here is the place you set up the site appearance, choose the site theme, turn on/off certain functions.

In my next post, I will talk about how to turn on the Badge function on course level and how to config a course Badge.

Math Visualization Apps

Math visualization is vital for students to transform abstract math concepts and to explore math topics. Traditionally math teachers have been using hand-held graphing calculators to help with this type of activities. However, powerful mobile device apps seems to make everything possible. Here we will review several iphone/ipad/android apps that can perform functions that traditional graphing calculators, such as TI-nspire can do, or getting close to them:

Free Graphing Calculator

Typing the keywords of “graphing calculator” in the iPad app store, you will see the first result is Free Graphing Calculator by William Jockusch (as of July 24, 2013):

This app provides a very similar function to some of current hand-held graphing calculators, as shown below. You can tell that this app can do: general calculation, geometry graphing, tables and several shape solvers. It also have in-app references on a number of mathematics topics, such as Algebra, Calculus, Fractions, etc.

Quick Graph

Another free iPad/iPhone app is “Quick Graph“. It provides similar functions although no in-app curriculum related contents.

However, it does have one extra function of 3-D graphing. It is also very easy to save all 2-D, 3-D graphing into jpeg format images for future references.

Free Web-based Tools for Math Visualization

Mathematics is known to be a beautiful yet very abstract subject. It may be easy for mathematician to visualize complicate equations and functions in their brain, but sometimes can be challenging for students or starters to do this. However, with the advance of computer and graphing technologies. In the following i would like to introduce a few cool tools that are free for math visualization.

The first tool that I like is Wolfgram Alpha. It is a very cool “Computational Knowledge Engine” (that’s what they call themselves). You can type in questions you want to know from basic algebra to a country’s population. Here I typed in the question of “how many people are there in China” since I am from there. They it will search and collect all information about China’s population and then generate charts based on information it collects:

Ok I know, we are talking about MATH visualization. So here it is: if you type in a equation or a problem, Wolfgram gives you the chart based this. For example, typing in: plot r=cos(3*theta/5), you will get this:

Or, it will solve equations for you:

Wolfram Education Portal

Wolfram also provides an educational portal. The portal is currently in Beta version (as of July 2013), and you will need to create an account in order to use it. The content of Wolfram Educational Portal is based on the open book of CK-12 Algebra and it covers but not limited to topics such as equations and functions, real numbers, equations of lines, graphs of equations and functions, solving systems of equations, and polynomials. These contents can be demostrated directly on the Wolfram Educational Portal website. Or teachers can download them to computer and then view them in the Computable Document Format (CDF).

The second interesting online math visulization tool is desmos.com

Having a similar function of Wolfram Alpha, desmos provides on-screen math equation creation “keyboard” for easy creation of equations.

Desmos is great for graphing at the k-12 level because it has sliders, can handle implicit relations, and can handle inequalities. However Desmos can’t handle calculus, which some high school students take.

Desmos allows multiple equations and plots in the same time, therefore students can compare the change of the plots when the factors of the equations change:

Type in an equation, then change the values of each factor, the plot on the right will change:
The exploration function on Desmos allows students to choose a topic on the left and then interact with the graph or modify the expressions:

Lastly, Desmos has a nice gallery of math plots that were saved and shared by its community members, which may be easily adapted to your class:

Teaching Math with Interactive Whiteboard (IWB)

Before we start talking about teaching with IWB, it is important to introduce a bit about IWB related software and supporting materials. Interactive Whiteboard companies and many other companies and projects have developed numerous supplemental instructional materials to exploit the interactive features of IWBs. It is these software and supplemental materials that make the teaching with IWBs more meaningful and student-centered. Without these software and materials, IWB “is just a big monitor and mouse.” (Granger, 2008) IWBs allow teachers to demonstrate concepts and ideas in an easy and efficient way.

Since IWBs can be used in so many different ways, it can be used in a variety of ways to assist math teaching and learning. Most commonly, an IWB can be used as a projector and support “Consider” type of math activities. Students can watch information from video clips, animation, presentation or other information displayed on the screen. An IWB can also support a discussion on a topic by connecting to a Classroom Response System (Clicker) and showing the polling results.

Using the interactive features of IWBs, teachers can demonstrate concepts and ideas very easily and efficiently. The following video shows how the teacher can use the Notebook Math tool by Smartboard:

The video below shows how an Algebra teacher wrote a function on the IWB and then the graph of the function showed immediately on the board with the ability of changing the shape of the graph with the change of factors:

Appropriately using IWB can make the “Practice” type activities interactive and interesting with the support of related Software.

For example, SMART Exchange is the community where SMART technologies related resources are shared. Teachers can go to this online community and then search for lessons, manipulatives, question sets, activity packs and gallery collections by grade level and key words. Use the filter on the left side of the screen to narrow down your search results.

IWB is also a very good tool for students to demonstrate their understanding about a math problem solving process.

In addition, IWB can capture your your students’ handwriting. can be seen in many classrooms to be connected to the computer and used as a projector to show the content on the computer.

Clickers and its Alternatives
I am writing a Technology Tool Kit course for middle school and high school math teachers. Before I started writing, I interviewed some math k-6-12 experts and a high school math teacher to get some ideas about what this course should cover. In my conversation with the highs math teacher, she mentioned her school used Clickers last year and people loved it. However, the batteries died and nobody has replaced them. Therefore, the teachers haven’t been able to use these Clickers since the beginning of this year. This is a shame.

I decided to put introduction to both Clickers and its online alternatives to my course. I found it is very good learning method by writing a course – you would think that you know “something”. But you may find yourself not knowing much when you really dig into the topic.

So here is what I found: You have two choices – buying traditional Classroom Response Systems (Clickers), or use their alternatives.

For traditional Clickers, there are a number of major vendors on the market. Almost all of them require a single one-time initial purchase, then registration fee for each semester – please correct me if I am wrong. Some of them actually support the connection to cellphones, tablet, and laptops. One piece of Clicker costs from $20 – $70 dollars, depends on the brand and type you get. You will also have to pay extra for an additional receiver, if your class size exceeds the limitation. Clickers can get lost, broken, or run out of batteries like the high school math teacher said. – I probably am biased, but I don’t like this option.

I explored a few alternative online tools that can achieve the similar functions of Clickers, and I like them.

First of all, for me, Poll Everywhere is the one that requires the minimum of students’ investment. It requires the presenter to have a screen and a projector to project the questions, and then students only need to have to have a cellphone – it doesn’t have to be a Smartphone and it doesn’t have to have web-browsers installed on it.

Some other online tools, such as Socrative, Mentimeter, SoapBox, InfuseLearning, also claim themselves to be able to work with cellphones, laptops and tablets – but these cellphones have to be Smartphones, and will have to have Internet connection and web-browsers on them.

More or less, these online alternative tools support questions types of multiple-choice, short answer(open ended), true/false, rating, ranking. Most of them also support PowerPoint presentation embedding. You will have keep the limitation of voters in mind:
- For a Poll Everywhere free account, it is 40 people per poll question; You can choose to pay to upgrade your account in order to overcome this limitation.
- For Socrative, it is 50 people per poll question;
- Mentimeter claims to have no limitation on the number of voters per question. However, it currently only has multiple-choice question type for free account.
