SXP288 Elluminate for NMR: Intepreting spectra

Visible to anyone in the world
This second NMR Elluminate tutorial is the core of the NMR tutorial work - it covers interpretation or prediction of the NMR spectra from protons within simple organic molecules.

We were provided with a short PowerPoint presentation of eight slides showing the structural formulae of three organic molecules and the corresponding NMR spectra.  Colour-coded version matched up the lines within the spectra to the chemical groups responsible for them.

As I am not familiar with this subject (apart from the short period spent teaching this module last year) I worked through all of the relevant module material.  I then found that working out the spectral features was relatively straightforward.  There was one feature whose details did not match up clearly to the rules of the simple models we used. I asked for clarification on this from the topic specialists on our dedicated support forum, but did not receive a response before the tutorial. 

The material covered in the PowerPoint was not enough for a tutorial as students would probably not to be sufficiently familiar with the topic to work through these examples within a tutorial. I referred back to the presentation I used last year. I had provided a summary of the rules at the start of this presentation. 

I made a few minor changes to improve the clarity of these slides, including stretching the content and darkening the colours. Then I rehearsed the presentation via Elluminate on my Tablet PC, using the pen to annotate the screens, including writing out the working.

My intention was to get the students to apply the rules for the examples. Therefore I extracted key screens containing the rules and placed them on our group forum for students to print out before the session.

In practise the session ran well. The students, although again reluctant to speak, did contribute and successfully worked through the three examples. They seemed to appreciate the exercise (though I have not had any specific feedback). I provided a pdf version of the annotated whiteboard screens on the forum afterwards.

SXP288 Elluminate for NMR: Chemical structures

Visible to anyone in the world
To support the students' work on nuclear magnetic resonance in SXP288 (Practical science: physics and astronomy) we need to run two Elluminate sessions fairly close together.  I decided to offer these fairly early as the information I had from students indicated they were making rapid progress through the NMR topic.  I used two Doodle polls to let students indicate their preferred days of the week.

The first session covers valency and covalent bonds, functional groups, structural formulae, naming conventions and isomers for some simple organic molecules.  The module team provide a short PowerPoint presentation based around fifteen slides including a few test questions at the end requiring students to identify structures and to draw structural formulae.

I reviewed the PowerPoint I used last year and made a few minor changes. This file ran to twenty slides. I had already included additional slides reviewing the naming conventions and I also split the test questions over more slides to improve clarity. I also stretched some of the images to improve the readability in Elluminate.

I prepared a pdf file from the PowerPoint slides, and used PDF Annotator (along with my Tablet PC) to hand write my speaking notes onto the slides. I also included all the annotations I planned to provide with Elluminate via the Tablet PC.

After printing this out I ran through the presentation myself.  I still felt that students would find applying the naming rules difficult during the test questions unless they had easy access to the appropriate material. Therefore I extracted a few key slides into a separate PowerPoint, and exported this to a pdf file. This was then posted on the tutor group forum along with a suggestion for students to print it out ready for the session.

I posted this file and discussed it within Elluminate with my colleague Sye Murray.

Al this activity took nearly a day.
