Classroom Exams Taken Online in Moodle

We have been receiving an increasing number of requests to have students take a test online in Moodle while in the classroom. In nearly all classroom cases, this will work without issue. The exceptions are our large lecture hall environments.

Wireless access in the large halls has been designed for normal Internet access. "Normal" means not everyone is actively accessing a web site, email or some other Internet service at the same time. When students are taking an online test, whether in Moodle or some other system, many more people are accessing an Internet service at the same time. In order for this to work, the density of wireless access points in the hall needs to be increased, and this increased density requires a change in the design of how the wireless access points communicate with each other.

This kind of work has been done in some of our large lecture halls, but many still need to be upgraded. ITSS is planning for this work, but in the short term we suggest you contact us if you are planning on doing online testing to make sure the hall you are in can accommodate this.

Other considerations include:

  • students have laptops or other mobile devices with them
  • battery charge is sufficient to make it through the exam

Please contact Bruce Reeves (breeves@d.umn.edu) if you are planning an online test in a lecture hall.

Email Etiquette

By Linda Deneen

You won't have far to go to find someone with a strong opinion about email. Email speeds communications, which can be a good thing and a bad thing. Certainly I don't want to return to the days of paper memos. I like being able to send out an email quickly and get responses efficiently. However, the speed of email also means that our mailboxes get clogged up with lots of email. Anything I don't want to see, I consider to be spam, no matter how well-meaning the sender.

Here are a few articles on email etiquette I found out on the web. Please take a few minutes to read one or two of these. Then think about your own email practices and consider modifications that you find appropriate.

Mobile Accessibility

Mobile accessibility generally refers to making Web sites and applications accessible to people with disabilities when they are using mobile devices. Traditional Web accessibility and its best practices are influencing mobile design and can result in universality.

Accessibility's Impact on Mobile

Traditional Web accessibility solutions are contributing to solving the types of problems that mobile experiences. Things such as on-screen keyboards and magnification have been staples in accessibility since the eighties. As Matt May, an accessibility evangelist, said in a video interview:

...what we've learned over decades of dealing with these issues in the field of accessibility is that the things that were needs for people with disabilities are now wants for lots of other people.

A transcript of the video, "Matt May talks about how accessibility has influenced mobile development and design," is available.

Overlapping Best Practices

Diagram: Mobile and disability significantly overlap in techniques. Disability's scope is slightly larger.

Many fundamental accessibility best practices apply to mobile interfaces and content. For instance, text and images need to meet relevant requirements for sufficient color contrast, screens need to be laid out in a way that permits intuitive navigation, and controls need to respond to multiple modalities of input.

A significant overlap exists in techniques for making a Web site accessible for a mobile device and for people with disabilities. As the W3C's Web Accessibility Initiative states:

Users of mobile devices and people with disabilities experience similar barriers when interacting with Web content. For example, mobile phone users will have a hard time if a Web site's navigation requires the use of a mouse...

They recommend addressing mobile and disability accessibility at the same time:

Following these two guidelines makes your Web content more accessible to everyone regardless of situation, environment, or device. Designing to the guidelines together, instead of separately, can make the process more efficient.

Universal Design

This all comes down to designing for the largest possible audience regardless of disability or ability and is known as universal design. It is an inclusive approach to design that honors human diversity. Matt May's "Wanted: Mobile Dev with 40 Years Experience" presentation slides detail its seven principles:

  1. Equitable Use
  2. Flexibility in Use
  3. Simple and Intuitive Use
  4. Perceptible Information
  5. Tolerance for Error
  6. Low Physical Effort
  7. Size and Space for Approach and Use

Universality and the Curb Cut Effect

Taking the lessons learned from accessibility and bringing them into the mobile space can contribute to universality and result in an "Electronic Curb Cut Effect." A multitude of benefits for other people can occur when developing technology products and services with accessibility in mind just as curb cuts for wheelchairs also help people with strollers, shopping carts, and wheeled luggage.

Severity of Problems
Bar graph: People with disabilities experience significantly more issues at more severe levels than mobile users.

However, curb cuts weren't put in for people with strollers, shopping carts, and wheeled luggage. They were put in for people with wheelchairs, because the of the severity of problems and consequences. People with disabilities have a moral, legal, and ethical right to access, which enables them as Matt May said in the video "to live a life unfettered.":

...you can solve people's problems by making things a little easier for them in their environment.

That carries over to everyone but it benefits people with disabilities most because you're integrating that problem. You realize if they can't do what they need to be doing they are actually being blocked from something. So it is more than a convenience. It is enabling someone to live a life unfettered.

Infrastructure Improvements

ITSS staff completed two major infrastructure improvements on January 5. On this Saturday, which coincided with OIT outages also planned for that weekend, we brought down most of our servers in order to do a major upgrade to our network. At the same time, we made improvements to our virtual server infrastructure in order to respond to problems that we experienced on December 19.

Both of these changes were very successful, and we expect that these changes will prevent a recurrence of problems that caused outages on December 19 and August 22. Both of these outages were traced back to errors in vendor-supplied software, but they were very frustrating nonetheless.

Setting aside the first Saturday in January was a very successful strategy for us to make these types of major changes with minimal impact. We anticipate taking similar action on January 4, 2014.
