Blogging Software

In a previous blog we showed how you could publish your presentations to the web. But, what happens when you want to organize your presentations in one site? Of course, you can get someone to build you a web page to put all your videos and presentations in, but this will cost you not only money but also you will depend on a webmaster to update your content.

If you don't want to depend on webmasters you can put up and update your site using blogging software.
The two best known are Blogger and WordPress. Both are not only free but you also get free hosting.

WordPress also has a free downloadable version that you may install in a server. In this case you will need to pay for installing and hosting, but once installed you will be able to update your site without depending on a webmaster.

For a start you may use one of the two previously mentioned hosted blogs. Should you need more power, you can move to the WordPress self hosted version.

This "Technology for Teaching and Learning" blog uses Blogger. Our new "Video and Lecture Center" uses the self hosted version of WordPress. Click on the image to visit the site.

Communicating with Google Wave

Communication Software: Google Wave

Communication software is a very important tool when using asynchronic e-learning. It is also critical when building collaborative teaching projects.

There are many types of software you can use to communicate, such as email, wikis, forums and chat.

Each of them has a distinct and unique set of main features.

E-mail is used by almost everybody. Conversations can be kept together and tracked. Wikis are documents that can be edited by more than one person. Forums keep messages and discussions together and allow editing by a coordinator. Chats allow real time discussion of two or more people.

Google has developed now a new tool that combines all of these in one application: Google Wave.

Every time you want to start a discussion you start a Wave. As with e-mail, you can add people you want to participate in the discussion. As in a wiki, everybody can edit the main post, as in a forum you may respond to the main post or individually to an answer. As in a chat, if two or more people are connected to the Wave, everybody can watch what the other persons are writing.

See below a Wave started by me:

Following is Gaby's answer:

Now I have added (edited as a wiki) inside my first post something Gaby will want to comment on: “Gaby: Tomorrow we are leaving at 6,30 am because I must arrive early to the hospital. “

So she adds her comment directly inside my post : “Can we leave at 7,30”

Something very useful about inserting comments is that you can collapse them clicking on the blue balloon where the comment was inserted. See the collapsed comment in the next image:

Digital Books

By Eduardo Mayorga.

Keeping up to date on knowledge has many pathways such as meetings, courses, journals, and books. Living in the digital era, digital books are one more option we have.

Digital books have 2 main advantages over paper books: 1) you can carry a whole library on your notebook or reading device, and 2) they are usually less  expensive than their counter part on paper. More important, for those of us that live in countries that have to pay for shipping, electronic books usually save us from 30 to 50% percent of the complete cost of the purchase.

One place to search for these books is the well known Amazon store and specially the Kindle edition.

Kindle is a reading device from Amazon that you can use to buy, download, store and read all the digital books you buy at Amazon. Until recently, you could only buy from the US, but know you can buy from abroad.

You can watch a video on Kindle here.

If you don't want to use a special reading device, you can also manage your Kindle account from your notebook or computer using a Kindle's PC software that you can download form here.

Posting Powerpoint Presentations to the Web

By Dr. Eduardo Mayorga
In past blogs, we have showed you ways to give a lecture to your students when you are away from the place they are, using synchronous communication tools.

But, what happens if you cant't be online at the same time as your students? In this case, there are ways you can deliver your lectures using software that will convert your PowerPoint presentation to a web compatible format.

One of many resources you can use is AuthorStream, a web based software that allows you to upload, convert and store PowerPoint presentations, with or without audio, and view it on the web as the following.

         Classroom vs web based teaching

AuthorStream has a free version (as the one we used above), and paid versions that may add more features.

If you need to post your presentations with more sophisticated controls, notes, search capabilities and quizzes integration, you can look at software such as Articulate. Of course this software is not free and you need a web site to upload your presentations. Articulate can provide this, but you get charged for this also.

The following presentation was built with the Articulate Suite. View the presentation

See you next month!

Social Bookmarking: Sharing Knowledge in the Web

By Helena Filippe   
According to Wasserman and Faust (1994) social networks are defined as a set of socially-relevant nodes, each representing a network member, tied to each other by several types of relations. Relations must always be defined in a relational context. A clinician’s life is all about building relations with others as in a network, with patients centered in our attention.

The learning process happens in a certain social context according to the constructivist paradigm of teaching and learning developed by Vigotsky.

The contemporary educator must bear in mind that he no longer detains the whole control over knowledge but more and more the role of a facilitator for the others around to build knowledge.
In this context it is not difficult to envision us doctors (educators and students) connected to each other thus defining the connectivism paradigm.

Social bookmarking consists in searching, storing, organizing, managing and sharing a data of bookmarks of web pages by tagging or labelling them in a collaboratively facion. A folksonomy or social tagging is then built.

In 2003 Delicious (www.Delicious.com) initiated tagging and the designation social bookmarking came up.

We lately decided to start social bookmarking in our residency group making use of this tool

to search, store, organize and share interesting ophthalmology websites that each one finds

We can very easily access anytime, anywhere the data selected, as a social network. Helpful and useful websites are continually being added thanks to the whole group contribution, in a collaborative way.

We save time, learn more, and strengthen our residency group both in intellectual and human sides.

There is an interesting video explaining how to sign up this Web 2.0 tool that can be accessed clicking here

Being at two places at the same time

By Dr. Eduardo Mayorga

Imagine this scenario: The head of the eye department has asked you to give, tomorrow, the lecture to the residents he was supposed to give at 7,30. You had promised your wife you would take her to buy new carpets for your house at 9. You live 4o miles from your hospital. No way you can make it back in time. What do you do?

Some time ago Karl Golnik told us about Synchronous e-learning. Today we will talk about 2 more tools that can help us with this task: Being at two places at the same time. We will learn to combine Skype, a communications software and Google Docs Presentation, a presentation tool.

Why combine if, as Karl showed us, there are tools that already have these two functions incorporated? I personally like this combination because they work better than any other, when you are not on a high speed connection.

Skype offers excellent audio and video and Google Doc's Presentation offers faster screen synchronization between teacher and students because it does not use screen sharing, as other collaboration software. When using Google Docs, teachers and students are synchronized in the same web page.

If you are not familiar with Skype you can find help on how to use it here. If you are not familiar with Google Docs Presentation you can find help here

Once you are familiar with connecting audio and video with Skype and you have uploaded you PowerPoint presentation to Google Docs you arrange your desktop to look like this.

Remember to activate the "View together"  function, at the right bottom corner,  to take control of the screen of all who are watching.

Questions from the audience can be done using audio or you can have the students write them using the chat area and answer all questions at the end of the lecture.

At this time, Skype only allows 5 connections at a time. You only need one to connect to the lecture room where your residents are listening to the audio from one computer , so you could have 3 other residencies attending or an invited professor from other place. There is no limit as to how many connect to the presentation area, so you could have in the same room, several residents watching their own screen and asking questions through the chat area.

If you need help using this combination or any other software mentioned in our blog, please contact us at elearning@icoph.org

Internet Resources for Teaching Evidence-Based Medicine

By Dr. Gabriela Palis

Evidence-based Medicine (EBM) is the practice of Medicine in a way that integrates the best research evidence with clinical expertise and patient values. This competency is widely recommended to be taught during residency, as a strategy residents should master for finding, appraising and assimilating the best available evidence from studies, and using it for their patients’ care.

Teaching EBM in Ophthalmology can be a challenge for many reasons:

• pre-graduate medical schools not always include EBM in their curricula, so residents’ first contact with this model occurs during residency;
  
• faculty are sometimes not familiar with the concept;
  
• ophthalmologists who are knowledgeable of the theoretical concepts that sustain EBM, and who will teach them to residents, are difficult to find for every residency program;
  
• EBM concepts are difficult to learn and assimilate, so teaching them can be time consuming.

Fortunately, there are some Internet resources that can help teaching EBM. I will describe three free resources I have found very useful:

• Understanding Evidence-based Healthcare: A Foundation for Action (by Kay Dickersin and Musa Mayer).This web course, created by the United States Cochrane Center, was originally designed to help consumer advocates understand the fundamentals of evidence-based healthcare concepts and skills, and is very good as a first introduction to the concepts of EBM. The topics it develops include, among others, what is EBM and why is important; the research questions; research design, bias, and levels of evidence; acquiring, appraising and applying the evidence, etc.

• PubMed^® Online: Excellent resource for teaching how to search and find the evidence. It includes PubMed Tutorial (based on the NLM’s one-day PubMed Training Course, in text format with animations, exercises, etc.) and the Quick Tours, animated tutorials with audio for learning how to search PubMed or how to optimize the use of MyNCBI, for example.

• CAT maker at the Center for Evidence Based Medicine (University of Oxford): This software tool helps create Critically Appraised Topics, or CATs, for articles about therapy, diagnosis, prognosis, aetiology/harm and systematic reviews of therapy. The software includes calculators for clinically useful measures and their 95% confidence intervals. With the calculator for therapy studies, for example, you can load the control and experimental event rates, and you automatically get the relative risk reduction, the absolute risk reduction, and the number needed to treat.

In summary, although daily practice and modeling of EBM are essential for learning how to practice EBM, some theoretical concepts are needed in order to understand the process and put it into practice. EBM resources available in the Internet are useful and easy to use tools that could help faculty teach the basis and practice of Evidence-based Medicine
