Hear Your Text: Benefits of Text to Speech

What happens when you get stumped while working on a piece of writing? Many writers, students, academics, and others choose to visit writing centers. More often than not, the first thing the writing center will suggest is to read the work aloud, and listen to what has been written. Why? Because your brain processes information differently based on how you receive it. Sometimes the key to writing is actually putting aside your pen (or keyboard) and taking a moment to listen to what you have written.

Therefore, many businesses are seeking e-learning tools that can help their lessons be more interactive and help bring the training to life. The content usually contains animations, quizzes, walkthroughs, games, annotated videos, etc. This blog will give a brief overview of some instructional design software that can be used to create eLearning Content.

Improve Your Video Lecture Production with Free Open Source Software

I’ve recently gotten into a “maker” mindset, becoming more and more interested in the concept of makerspaces, hackerspaces, and generally improving my ability to make, repair, or upcycle the things I use on a daily basis. Besides using my wife’s broken laptop charge port as a big impetus to learn to solder, or installing various Linux distributions on various old computers or single board computers I have, I’ve been spending time watching YouTube channels of various makers or Linux podcasts. One thing I’ve noticed is that the video production of these channels is often very good, even when they seem like shoestring productions.

Why don’t more online courses include podcasts?

graphic of RSS icon with headphonesWhen I was an undergrad, my “intellectual conversation crutch” was bringing up something from Jon Stewart’s Daily Show. After moving to Chicago, that crutch morphed into inserting something I read in The New York Times or New Yorker.

Now? “I was just listening to a podcast about that…” is something I say with annoying frequency.

Thankfully, I’m not alone, as I notice many other people parroting back something they’ve recently heard in a podcast. But even though it feels like most of us are listening to podcasts, and most of us are learning interesting things from podcasts, I still don’t see podcasts as a top option when faculty are designing online courses. Why might that be?

Digital Story Telling

Silhouette cartoon figures listening to a storytellerDigital story telling is an instructional practice that is used to tell stories by using computer-based tools. For example, individuals or groups may tell a story by using a variety of multimedia such as audio, graphics, voice, text, and video. For centuries, many people have learned messages from stories that were either passed down orally or written in a book. We now live in such a technological advanced society that learners can now comprehend an intended message by using technological products of the 21st century.

Ockham’s Razor and Online Learning

Rube Goldberg's Self-Operating NapkinI’ve always loved Rube Goldberg’s drawings. They lent a certain sense of the absurd to everyday tasks, creating a ridiculously complicated machine to handle something most of us could do without even thinking about it. Like many young people, I also delighted in building machines similar to Goldberg’s, using every toy at my disposal to produce something that, let’s be honest, may have been more satisfying to design and build than to actually deploy most of the time. A few hours’ work for ten seconds of payoff? Not a big deal, when you’re a kid.

Harnessing the Power of Audio

The other day I was talking to a colleague about developing a new program and how he could best deliver content, especially lectures, to his students who would be scattered around the globe. Naturally, we talked about video and presentation best-practices, but he pointed out his sympathy for students who work full-time and still have to carve out a period to visually focus on a lecture.

The instructor also told me how he balanced a busy schedule and keeping up-to-date on things by listening to podcasts. They are perfect for commuting on transit systems, flying around the world, and doing chores around the apartment and he wondered about how he could create podcast-like content for his students.

Is Video Right For Your Course?

When I’m contacted by faculty who want help creating video for their courses, one of the first things I ask is why they want to make a video. Most of the time it’s to add some instructor presence in an online or hybrid course, but often it’s to replicate a lecture they’ve given in the face-to-face version of the course.

I’m always a bit apprehensive as I tease out the reasons for the request. I don’t want to trespass on the instructor’s prerogative to teach the course as s/he wishes, but I do know that many of the videos I see don’t serve their intended purpose—assuming the purpose is to promote learning or add instructor presence.

Make Your Voice Heard, Part 2: Audacity Audio Recording and Effects

See Part One: Choosing the Right Microphone

Now that you have a good recording setup in place, the next steps are getting something recorded and making it sound good. There’s a huge variety of options for recording audio, but I’ll discuss using  Audacity in particular here. To be sure, there are much more powerful programs than Audacity, but they tend to be costly and very complicated to use—which won’t help people who aren’t interested in professional audio and just want to record something for people to listen to.

Here’s why I recommend Audacity to most people, especially beginners:

Make Your Voice Heard, Part One: Choosing the Right Microphone

The more we create and share resources with others online, the more important it is to make sure that our voices are heard…literally. Choosing the right microphones, recording room setup and techniques, and audio file formats can make a startling amount of difference. This article is the first in a series that will help you know what to look for, what to avoid, and how to get the best sound wherever you are. This time around, we’ll focus on microphones.

The first step in recording good audio is choosing the microphone that will be listening to you. Every microphone has a particular pattern in which it receives sound waves from an audio source, called a pickup pattern. The most commonly used types of microphones are omnidirectional, bidirectional, cardioid, and shotgun. Continue reading
