EDCI 337

While I ran the WAVE accessibility report on my Module 1 blog. I found out that there were several errors and alerts that I didn’t find when I was posting it. The report highlights 7 features, including a figure, form labels, skip links, and language specification. These are positive indicators of accessibility. I expected the accessibility to be relatively good since the contents are text-based with straightforward formatting. However, issues like contrast errors and skipped heading levels are overlooked but are common accessibility pitfalls. The most surprising finding might be the contrast errors, the contents are text-based with straightforward formatting, I never expected to have 11 errors like this. Another unexpected aspect might be the skipped heading levels, I never thought that part was missing, this can impact the navigability for users relying on screen readers, highlighting the importance of a well-structured heading hierarchy.

I have used text-to-speech tools before. We were learning about what disability people’s daily life looks like, and my assignment was to try to use these tools to experience people with hearing impairments’s daily life. I found that IOS does way better on accessibility compared to android. I don’t think it had different choices for voice at that time. I think they are super useful for people with disabilities. I personally think that the original robot soud voice ( from Read Aloud) sounds emotionless and stiff, which makes me less want to use them. But the new generation, the more human sound voice sounds way more comfortable and makes me want to use it more.

To me, Inclusive design means creating products, experiences and environments that can be accessed, used and enjoyed by as many people as possible, regardless of their abilities, background or any disabilities they may have. It’s about recognizing that people have diverse needs and making intentional choices to ensure everyone can engage meaningfully without facing barriers.

H5P

WEBER’S LAW

Weber’s Law is a principle in psychology that helps explain how we perceive changes in stimuli, such as light, sound, or weight.The “just noticeable difference” (JND) is the smallest detectable change (∆𝐼) in a stimulus (𝐼). The JND is the smallest detectable difference between two sensory inputs. For example, if you are holding a weight, Weber’s Law tells us how much heavier an object must be for you to notice a difference.

The JND is proportional to the magnitude of the stimulus :

(∆𝐼/𝐼) = K

where K is the Weber fraction.

Examples in Real Life: If you’re listening to music at a high volume, you might not notice a slight increase in the volume, but at a low volume, the same increase would be more obvious.

My experience of trying out H5P:

I used the multiple choice and drag and drop features in H5P. I think it’s a very convenient tool that allows me provide better interactive learning experience. . It allows me to incorporate quizzes directly into the learning process. It perfectly fits Merrill’s first principles of instruction where “Learning is promoted when learners are required to use their new knowledge or skills to solve problems”. Learners uses what they have learned to solve quiz which enhances their understanding of the materials.
I think I’ll use the interactive video and interactive presentation the most. Both allow me to pause the material at specific points, present a quiz, and then seamlessly continue with the learning material.  I think they makes the learning experience more complete. If I use other testing contents like multiple choice or drag and drop content or true or false and I want to continue the learning material afterward.I would need to create multiple sections and intersperse the quizzes between them. I wanted try the interactive presentation feature but my WordPress was missing some necessary  plugins.
I think the interactive video requires most resources. Compare to the others, it not only requires images, texts and tests, it also requires audio which means that the presenter in the learning material must be prepared and clear.

I feel the audience for this screencast consists of people who have some interest in basic study or experience in coding or computer science. That’s why I didn’t mention too many details on fundamental coding knowledge, like what coding and datasets are, what coding language I’m using, or how to run the code. So, for people with no basic understanding of computer science, the content might be confusing. However, for those with some basic understanding or experience in coding or machine learning, the content should be very simple and clear.

Limited capacity (Cognitive Load Theory) is the most intuitive one. When I attended the face-to-face course in UVIC, I found that there are reasons that the course is designed to this length. One of the reasons is that as the time reaches the end of the course, I find that it’s getting harder for me to keep concentrating. And I found out that even though some courses have longer lecture lengths, the amount of time that I can focus on does not change much. The most surprising one is the Image Principle. I found it surprising that having the presenter onscreen during a presentation doesn’t enhance learning and might even be distracting. I found it makes sense to relate to the online courses. I sometimes ended up staring professor’s face and got totally lost in the lecture.

Hi, I’m Miya. I’m a second-year student living in Victoria. I love doing academic work during the night. My major is psychology. I usually prefer Zoom or video call as the mode of remote communication. Being good at listening is my communication strength. I do not often express my opinions and thoughts because I’m an introverted person.
I found this course interesting for several reasons, largely because it fundamentally transforms how we approach education and knowledge acquisition. Multimedia learning provides multiple avenues for understanding, making education more inclusive. It also allows us to control the sequence, pace, and depth of learning, giving them autonomy and making learning more personal. It also gives us feedback from peers and makes connections more easily. Also, there is a lot of teamwork that I can figure out with my team together.
