Max Mahoney (Chemistry) is working on printing SpecPhone, a 3D-printed smartphone spectrophotometer develop by Dr. Adam W. Smith’s lab at the University of Akron. From the developer:
The SpecPhone is a 3D-Printed smartphone spectrophotometer for research and education. The device can make analytically accurate measurements of concentration and can be used for teaching analytical chemistry and DIY science projects.
After some sketchy results and strange print decisions by the Ultimaker, it seems that the model doesn’t quite sit flat. That is, the legs don’t seem to be the same height. Using Netfabb Basic, I dropped in a Z plane to visualize:
Taking that plane up, it seems that it’s not just the bottom of the model, but that the skew continues all the way to the top:
With support structure enabled in Cura, we were able to print it after a few botched attempts, so it’s not a deal-killer, just a bit awkward. Now we just need to find an iPhone 5s…
Field day with Jason Pittman’s (Geosciences) mapping class yesterday. We flew the 3D printed picavet for the first time. After we worked the wetlands, two student volunteers agreed to walk the balloon up into campus, as I wanted to get shots of the garden. That little patch of green in the dry area (above) is the garden. Image below from a different flight for comparison.
The entire dataset can be found at the project blog (DoLookDown.org), as well as the images from our 2014 and 2015 flights of the same area. When I find the time, I plan to redesign and 3D print the picavet from the ground up, shaving some additional weight.
With the accreditation team visit scheduled for the week ending October 9, 2015, the information below might help to jog your memory if visiting team members ask about DE issues, including Regular Effective Contact and Accessibility:
Regular Effective Contact/Regular Substantive Interaction
- Title 5 defines REC, and stresses the importance of “instructor initiated” contact with students in DE courses.
- REC is the thing that distinguishes DE courses from correspondence courses. FLC does not offer correspondence courses.
- REC is required in both hybrid and online courses. That is, the face-to-face time you spend with your students in a hybrid course does not count as “contact” for the purposes of REC, and you should also maintain contact with your students for the online parts of your course.
- The college has a set of guidelines for online, hybrid and web-enhanced instruction: https://docs.google.com/document/d/1E2fpEQx5kY_lJ3EDf7OJaZv1F8qEjBc-DA7if-hjTzA/edit?usp=sharing
- The district “audited” REC in online and hybrid courses last semester, using the metric of 1 contact per unit per week. For a 3 unit, 100% online course, this would be a minimum of 3 contacts per week. In most courses audited, the contact was evident. In some, contact occurred but was not visible to the auditors, and DO requested additional information from faculty teaching those courses.
- REC can be accomplished in a variety of ways and using a variety of tools, including but not limited to email messages to students, responses to discussion postings, news items, and other forms of feedback.
- The DE course checklist linked below might help you assess REC in your course: https://docs.google.com/document/d/1WdCY14pQ0w-eqlwFl6t4E8i3xEQk1oQ52Z8NIVR7mwk/edit?usp=sharing
- @One offers a very much more in-depth rubric entitled “Standards for Quality Online Teaching” that you may find helpful: https://dl.dropboxusercontent.com/u/60279976/%40ONE_SQOT.pdf
- While it isn’t perfect, D2L as a platform is considered generally accessible to students with disabilities.
- The law states that all video files in your online and hybrid courses should be captioned.
- The law states that you should provide a transcript for all audio files in your online and hybrid courses.
- If you have content in your online or hybrid courses that doesn’t meet accessibility guidelines, it’s important to be aware of and work toward compliance.
- For more information about captioning, you may wish to view this desktop seminar from @One: http://www.3cmediasolutions.org/node/17912
- 3C Media Solutions has a grant-funded captioning service, and you can request captioning for videos that you upload: http://www.3cmediasolutions.org/sites/default/files/How%20to%20Request%20a%20DECT.pdf
- The college will soon be hiring a .6 Education Media Design Specialist, a permanent position working out of the DSP&S office to assist with accessibility issues.
Greg Beyrer (CRC) created this great resource about using Outlook rules to document Regular Effective Substantive Contact when sending emails from D2L. Check it out:

Here’s the view by county.
Here are the D2L usage figures for Fall 2012:
D2L Sites = 350
Graded Components (FLC course sections linked to D2L Sites above) = 426
Faculty Using D2L = 150
Student Enrollments = 12,643
The difference between D2L Sites and Graded Components indicates that some faculty maintain a single D2L site for multiple sections of the same class. For instance, if a faculty member teaches 3 sections of Nutrition 300, they might choose to set up a single D2L site for all three sections.
Here are charts showing FLC’s D2L usage across the above four dimensions from Summer 2008 (when D2L first became available) to the present:
