Teaching does not imply learning. If we comparare traditional face to face courses with online asynchronous courses we will see that traditional face to face courses usually only focus on the ‘transference” phase. This means the teacher speaks the learners listen with little or no interactivity. For learning to happen our courses should also focus on the “processing” phase, where learners incorporate, process, store, retrieve and practice, applying the new knowledge or skills to real life scenarios.
Online asynchronous courses allows us to change a teaching experience into a learning experience by adding activities and resources that favor the “processing” phase such as pretests, multimedia presentations, documents with text with graphics, mind maps, discussion forums, scenarios, assessments and continuity over (time because learners can come back to the course as needed after they finish it.)
In this post, we will show an inexpensive way to build your own DIO (Digital indirect Ophthalmoscope) with parts you can order online.
The DIO is a useful tool for teachers to video record what they see in the fundus and then show and explain it to their learners. Also for learners to record what they see on their own, and then show it to their teachers.
The DIO has been described by several authors in the past. References can be found in the poster published by Guillermo Monteoliva, Gabriela Saidman, and col., which you can find in this link.
The main problems Guillermo and Gabriela had building the prototypes were the flexible arm and its attachment to the helmet and the camera.
Based on these needs, their previous experiences and some parts I use when recording GoPro videos, we came up with the prototype you can see in the video below.
The GoPro arm and attachments can be bought in any GoPro store. The phone holder can be ordered at this link. Phone holder
Google is one of the most used search engines. Even sometimes discredited for academic work, it can really be of great help, especially if you use it to build upon what you look for with other “more academic” search engines.
Many of us forget, that as any other search engine, searches can be refined using operators. Take a look at this infographic that will help you review in an easy to read format some of the operators and search strategies you can use.
Many times, during a PowerPoint presentation you may want to show a live web page.
What we usually do is create a hyperlink that opens a browser and you must leave the PowerPoint presentation to show it.
A more elegant way to do this would be to embed the website in your presentation.
The standard PowerPoint does not allow this. For embedding a web page, you need to download an add-in from the Microsoft App Source. I use “Web Viewer”. You can get it clicking here
Watch the video below to see how to do it. Then, keep on reading.
Some tips to remember:
Make sure you embed only a secure site (https://) and that all the pages you are going to navigate to are secure. Test it all at home.
Make sure you will have an Internet connection where you will be presenting.
Be prepared for the Internet connection failing. For this,
a. capture screen images of the pages you want to show and add them to your presentation
b. Hide the pages so they will not show in case everything goes well
c. If things fail when you test on site, hide the slide with the embed site and unhide the screen captures.
