Images, Text and Audio Part 1 LTEC 5220

After reading the prompt for this unit, I immediately thought about how a standard lecture in a modern-day classroom also has visual/ images/ auditory stimuli.  At least one with a well-designed PowerPoint presentation. Lecture has the added bonus of discussion, and allowing the teachers to adapt their lessons to their situation.  That isn’t necessarily a knock-on technology that can provide the audio/visual experience.  It is saying that the modern classroom also is evolving and bettering itself wither it be a chalkboard, an overhead projector or a PowerPoint presentation.
That being said, taking this completely online, grad school program, I see the benefits of having the technology to use images, text and audio.  Reading long articles in PDFs can be difficult.  The extra audio and images sense would help me understand it.  Not to mention be helpful to the blind and the dyslexic.   
While the reading of long PDF articles makes sense for a graduate school, for the average student, it isn’t.  Online classes have proliferated.  With the proliferation of online textbooks, even traditional students have the ability to hear audio when reading.  
That being said, is the excessive amount of interactivity preparing students for upper level courses? Moreover, there designing with images and audio can lead to sensory overload, or as mentioned in my cognitive psychology class, overloading the cognitive load.
As a teacher, I plan to add more images and videos to my PowerPoint presentations.  I have a lot of homebound students.  With the recording devices I have, maybe I can record something for the student for them to have at home. I have certainly moved in this direction with laboratory experiments. I have added videos and audio sections to my instructions. 
And while the teacher, should add more interactivity to their lessons, adding an audio component to a student project might also be something to help learning. As the old adage goes “the person doing of the work is the person who is learning”.  I certainly have found that reading my script over and over has helped me understand my topic of baking bread far deeper, than if I just used images and text.  Having students record parts to something like a poster presentation also would be beneficial.

In the end, technology continues to change.  Audio recording and interactive pdfs would have been unthinkable 20 years ago. I can image what something like 3D printing can do to engage not just the audio, or the visual, but the kinesthetic part of the brain.

LTEC 5510 Week 6

Week 6 Blog In your Blog reflect on the following items: You have begun putting together your full course. What has gone well? What has challenged you? What feedback have you received? What feedback have you given? What have you learned from the process of developing instruction in an LMS? Creating an online course has a bit of a learning curve.  Converting old lesson plans from my teaching days to online learning has been challenging.  My PowerPoint presentations turned screencasts are good examples of these differences. In a face to face classroom, it is good to have lots of questions while lecturing. This keeps the audience participating and interested. With video, that option is not available.  I also miss the verbal and non-verbal feedback I got from the classroom. Those cues helped me know what parts of the presentation to skip, and which parts to go in more detail.  Perhaps, using synchronous sessions could bring back that element of teaching. Writing ...

LTEC 5510 Week 13

Week 13 Blog: My course is pretty much complete. Additional feedback from peer reviews will be necessary, but I don’t plan on making any drastic changes.   I have a rough draft of my job aide done, and it should be finished after I get my feedback from my partner. I assumed that the Job Aide was going to be one of the more difficult parts of this course. I don’t like writing long papers. But when I started discussing how the class worked, I found it very easy to write. The only thing I have left to do is the presentation. While part of me thinks it won’t be that difficult, I know better than to believe that. I entered this course believing that my material as a biology teacher would have made the creation of the course simple. I predicted wrong. While it was nice to have old worksheets, PowerPoints, quizzes, and links to YouTube videos in my career, that in many ways slowed me down.   Having old material made me a little complacent.   As someone teaching the sa...

LTEC 5510 Week 11

Week 11 Blog By the end of this week, your full initial development must be completed. Were you able to finish according to your timeline? Why or why not? What technology challenges have you faced? What “people” challenges have you faced? How have you sought to overcome these difficulties? What have you learned about completing a major project within a professional deadline? What will you do differently next time? What were your strengths as a designer? What do you need to improve? What a difference a week makes. Due to COVID 19, I got furloughed for a few weeks.   Thus, I had a lot of free time this week, and I have been able to get a lot done. It is incredible how much I could get done when I don’t have a full-time job to worry about. There are a lot of challenges in this course. My old teaching PowerPoints had a lot of breakpoints where I could ask the class a question, do demonstrate something. I had to spend a lot of time rewriting my PowerPoin...
