Abstract
Developmental Anatomy Integration into Clinical Anatomy Education using Online Embryology Resources

Clinical anatomy pedagogy was traditionally taught through wet specimens and is now supplemented by a range of videos and other online resources. Clinical embryology was also traditionally taught as "micro-anatomy" using models and/or histological sections from key stages of development. This methodology was always limited in both scope and accessibility. This presentation will demonstrate how dynamic events in embryology can be integrated into new developmental anatomy educational methods.

In 1996 online embryology education at UNSW began with histological sections and a small number of other support resources. In 2004, a new Medicine program began that “blurred” the discipline approach to clinical anatomy teaching, now being integrated into broader cross-discipline “scenarios”. This also provided an opportunity to redesign embryology lecture and practical resources that students could access during and outside of face-to-face teaching times. In 2009, these integrated resources were moved to a new “Wiki” platform, allowing student contributions and knowledge assessment through quiz format items. Pedagogy now is a broad mixture of educational resources classified by anatomical systems and integrated into developmental timelines including: text, histology, normal and abnormal anatomy images, scanning electron micrographs, animations, ultrasound, magnetic resonance imaging, research materials, links and online textbook access. Content can be easily updated in response to student feedback and accessed from anywhere with internet access, opening the possibility of MOOC teaching. Students can now relate both normal and abnormal development to the clinical adult anatomy.

About these collapsible tables
Mark Hill.jpg
Ever wanted additional information to be available to the reader, but want the the online material not to be cluttered with your useful (but long winded) explanation? Along comes collapsible tables. Yes all those important remarks, links, pictures, movies, or expanded explanations can be hidden and await the reader clicking "show". Just as quickly the information can be collapsed away again by clicking "hide". A very useful tool, don't forget to give the table a name that hints at its content.

Movies

  • Here is a real human conceptus in the first week of development.
  • The actual movie page has a full timeline text description of the developmental events occurring in the video, as well as some labelled images.
  • It can be displayed in full screen mode and stopped, started and dragged both forwards and backwards to demonstrate specific events or features. Also
  • All movies are available in both Quicktime and Flash formats (flash will not play on iPhones or iPads).

Categories

  • Note at the bottom of the actual actual movie page a list of related topic categories.
  • Clicking a topic will open a category page listing or related pages and media. Try.
  • Categories can be added to any page or uploaded file to help identify and organise related content.

File usage

  • Any uploaded file (image, movie, audio file, PDF, XL spreadsheet, Word document) when opened by itself will also show the pages where the file is used on the site.
  • For example open File:Human_blastocyst_day_1-6.jpg and scroll down to the "file usage" section, at the time of writing this will show "The following 9 pages link to this file."
  • These 9 pages can also be opened directly from the list.

Medicine

Medicine Student Projects

  • Part of the Medicine undergraduate program allows for individual students to work on research or educational projects related to medicine.
  • The projects are academically supervised and are described as an "Independent Learning Project" (ILP).

Science

Science Student Projects
  • Since 2009 undergraduate science students have been preparing online group projects as part of their ANAT2341 Embryology course.
  • Student group (4-5 students) selects a specific topic within the main theme that they then research and work collaboratively on that topic throughout the semester.
  • Project is discussed online.
  • Assessed by peers, before being finally edited for submission as their group assessment component for the course.
  • Group and Individual contributions can also be monitored.

Concluding Remarks

  • Model for developing online education resources in embryology (1,731 Content pages , 8,066 Uploaded files, other academics and institutes can develop their own resources here).
  • Can be accessed and edited from anywhere with internet connection (including iPhone and iPad through browser or Application)
  • Parallel pathways in learning, many different ways of explaining specific developmental concepts (Medicine | Science | Movies | Embryonic Development | Human System Development | Human Abnormal Development | Histology | Categories)
  • Relates (and accesses) historic and current research findings and directions.
  • Allows content linked Quizzes.
  • Allows easy student online project work.

Educational Links


Help me, please....
Mark Hill.jpg
Lost, confused? There are many Help Pages designed with the novice user in mind, describing or providing online tutorials in navigation, editing, copyright issues, tables, images, referencing......

I did not get the opportunity to cover all the online topics in my talk. If you are looking form more look in Animals or Explore in the lefthand menu (on every page) or simply use the search window at the top of the page for your topic of interest.

I am always happy to receive feedback on your educational experience, errors or omissions on the site.

Finally, and most importantly, I thank all my Contributors who have helped make this a site so rich in embryology content.
