Inquiry to teach bone anatomy and design

31 Oct

Goal: In my anatomy and physiology class students need to learn about bone anatomy and have them understand the following:

  • Shape of a long bone
    • Hollow middle
    • Ends of long bones are wider
  • Discover that there are actually two types of bone *spongy bone and compact bone)
  • Location of spongy bone vs compact bone
  • How does the design of a bone accomplish the structural/support needs of humans

Previously this would have all been taught via a lecture and discussion where I would tell the students all of the information.  This year I decided to have the students discover how and why bones are designed the way they are.

Students move through a series of six stations that have 1-3 real bones. (human, deer, cow, and mastodon) While at these stations, students record observations on their iPads about each type of bone, including the shape, and the structural design. In addition students take pictures of the bone and in some cases place magnifying glasses in front of the camera to take pictures of the bones. Through these observations and just a little bit of research students discovered and learned for themselves all of the learning outcomes I had previously given them.  Take a look at some of my students work!  Pretty amazing!Intro to Bones

Students use iWork apps to produce more comprehensive lab reports

Creating More Comprehensive Student Lab Reports:

As we began looking at ways to incorporate the iPad into our science class we were not always looking to completely flip our already successful curriculum on its head, but rather ways we could enhance particular areas.  One way we did this was to have our students use the iWork apps to create media rich laboratory reports.  Having students create their lab repots within the Pages application allows them to incorporate both still images and videos directly into their reports allowing them to capture a greater picture of their learning then a typical printed version.

What we did:

  1. Created and distributed via Dropbox or WebDave a template lab created in Pages.  This template has a number of useful information.
    1. Directions for the lab are at the student finger tips
    2. We recorded video directions for some of our labs where students needed to see how to do something.
    3. Students could read the directions, answer pre-lab questions and watch the instructional videos before coming to class.  This saved precious class time needed to complete the lab and insured students had the necessary information before starting the lab.
    4. By creating a template for students to download and use we provided the overall layout of the lab including  prelab questions,  step by step instructions to complete the lab, analysis questions and predesignated areas for them to import images, videos, tables and graphs.
  2. Used the Numbers app to create a drop down menu template for students to use in our digestion and cardiovascular labs.  By creating a table with columns that have set choices in a drop down menu our students had to create a comprehensive table of biomolecules digested, the location of digestion, enzyme responsible for digestion and the products of that digestion.   (See images below)

What the Students Did:

  1. Students captured images and imported them into the free app called Skitch that allows them to label and annotate  their images before importing them into their lab report in Pages.
  2. Students used the Numbers template to fill in information about the enzymes involved in digestion
  3. Students captured video to record certain stations in the lab.
  4. Answered pre and post lab analysis questions
  5. Submitted their lab via WebDAV to our local network folder.  (If you don’t have WebDAV and you are using Dropbox you can use the website http://otixo.com/ to link the iWork apps to dropbox.
