This Little Piggy...Dissection with a Twist of Technology and Splash of Tradition

One portion of a biology curriculum that always faces questions is dissection. There are feelings of extreme support and extreme disapproval and everything in between.  Fortunately, I teach at an institution that fully embraces the exposure of students to dissection.  My syllabus includes a week long dissection study of the fetal pig. We use this organism because it gives students the best small size model of what their bodies look like on the inside. The fact that they can actually hold a four chambered heart is fascinating to them. Seeing and feeling all that we talk about is so much better than just accepting that these tissues and structures exist.  Knowing that not all of my students share the same enthusiasm for this type of lab, I do make sure I have parameters and options for all levels of interest. 

1. Knowing the anatomy and physiology is mandatory for the course; touching the pig is not. This is a real worry for some students that needs to be put to rest sooner than later. Virtual dissection is always an option for my students.




 2. Dividing kids into groups based on comfort level makes for smoother lab time. I have students fill out a questionnaire based on 1-3 scale; 1 being ready to "fly solo" and 3 being "I need oxygen to get through it" option. Honestly though by week's end, they are almost all at the "I want to do this again" level.

3. Providing virtual dissection options helps for at home review.  My favorite options for out of class study tools are the Pig Dissection App from Kids' Science  and the Whitman College VPD and Biology Corner Pig Review websites.

4. Requiring a comprehensive assessment gives a defined goal. I set up a practical test where kids rotate through stations to identify structures, functions and systems of selected organs. This gives them the feel of a "gross anatomy" exam and encourages groups to look at other specimens besides the one they are using for their work.

5. Having a relaxed atmosphere with fresh air is a definite bonus!  This may not apply to everyone, but it works for us (disclaimer: be ready for extra lab attire if the weather isn't ideal). We set up a tented area outside for dissections that allows kids to step away if needed, but also provides a great opportunity for all levels of science to be exposed to different organisms. Our life science students were studying worms, grasshoppers, squid, crayfish and frogs, while our advanced biology students were examining cats, sharks and rats, and our biology students were in the mix with fetal pigs.  It is always enjoyable to see our 7th, 9th, 11th and 12th graders all together in one place learning science!

Please DO Ask Questions and Make Comments During the Movie!

Today I used a new twist on the old... Today'sMeet. The old is watching a movie, and the new is being allowed to have a conversation while the movie is playing!  I learned about this website back in November from Shawn McCusker (gowhereyougrow.wordpress.com) and am finally putting it to use. 



By using Today'sMeet, I am looking at the "back channel" of my classroom. What are back channels you might wonder? They are the behind the scenes conversations and notes that students use to seek clarification during classroom activities. They are secondary conversations to what is primarily happening in the classroom.  

We started the movie, Gattaca, in biology today. If you haven't seen it, the plot consists of a society in the "not so distant future" that uses genomics and biometrics to create and organize society. Students have many questions about the movie, especially on the first day. Before class, I created a Today'sMeet url for each class. It is very simple and lasts for a set amount of time. I selected ours for one week. This url is then provided to students to join the chat.
 
When my students came to class, they used their assigned iPads to log on to the network. I then explained the "Rules of Theater 416." Your rules need to be well defined. Posts cannot be erased and are seen by all who participate. 

This is what the conversation looks like on the iPad screen.
 I kept the rules clear and simple:
1.       Only have the Today'sMeet page open on your iPad. All other apps are closed.
2.    Log-in using first name.
3.       Post an original comment or question during the movie.
4.       Respond to another student’s comment or question during the movie.
5.       Any unacceptable posts will result in a zero for the assignment.

So, how did it go? Check out this screen shot for the answer.  This is just a portion of a conversation during the first 30 minutes of the movie.


This is a screen shot of a portion of the transcript from one class.
I launched this idea today hoping that it just wouldn't crash and burn. Instead, I am marveled by the genuine interest and dialogue shared by my students. I can't wait to see what I will learn from them tomorrow.
