Learning Anatomy through Collaboration, Part 1

We’ve been away from one another for far too long.

Talking over Zoom, email, feedback and peer edits on documents and drawings can only go so far.

Mink Intestines in Anatomy

Mink dissection – look at those intestines!

Most of the students in this Anatomy and Physiology class in our small rural school have been together for years, some since kindergarten. Some are related; in fact, this class of 14 students has two sets of twins.

To begin the year, we use the classic “Draw Yourself” lab, in which students pair up and one student traces the body outline of the second student on a large piece of posted paper. Students then label regions of the body, quadrants of the abdomen, and directional terms used for describing the body – anterior, posterior, dorsal, ventral, sagittal, for example.

The benefits of this work, as opposed to me lecturing and students memorizing:

  1. Students get acquainted, or re-acquainted, with one another.
  2. Students are actively working, that is, moving around and acquiring a kinesthetic introduction of the human body and the terms they will be using all year.
  3. While working on their creation, students see the terms in print, read the terms aloud, hear others say the terms, and write the terms. Over, and over.
  4. Students visit other groups to ask questions, give suggestions, and get ideas for their own work.
  5. And, importantly, students learn how others learn.

We will use these large paper bodies over and over, throughout the year.  Stay tuned.

End of Year Science Scavenger Hunts

A few decades ago, I wrote a scavenger hunt for my AP Chem students to do After The Test.                                                                                                      It’s gone through many iterations, and has been modified for a general chemistry class. A Biology version soon followed. It’s a great end-of-the-year activity as students must apply what they’ve learned all year and make connections among several concepts. The hunt can be done as an out of class assignment, or time in class can be given for students to plan the items they will use and write the index cards. I’ve had students work alone, in pairs, and in groups or 3.

Here’s how it works:

All Means All Part 3: Graphing our Learning Styles

This is the third in a series of blog posts summarizing my reflections on what it means to provide learning opportunities for every student, every day. Find the series here, at  #AllMeansAll 

 
Evaluating-learning-styles
Disclaimer: I’ve read a good deal of literature and opinion around the validity of learning styles. Nonetheless, at the encouragement of a colleague (this colleague) during some collaborative course design work, I pulled out the learning styles inventory* again this year, in Physical Science classes. The intent was to use the data gathered to introduce graphing, and that was a win.  The colleague suggested we share with students WHY we are interested in their learning styles. We are interested so that we can be sure to make learning available to all students in the modality each student best learns. We discussed this in both classes. The real win, though, was what I learned about my students, and what they learned about themselves.

All Means ALL, Part 2: Engineering Design

This is the second in a series of blog posts summarizing my reflections on what it means to provide learning opportunities for every student, every day. Find the series here, at  #AllMeansAll 

Created during Champions of STEM work with BSCS, who probably own the copyright. If asked, I will remove the image.

On the first day in Physical Science, we got into teams and built paper towers as an engineering design challenge. Our process followed the outlined by a group of district STEM teachers working together last school year.

The challenge was simple: Build the tallest tower you can with 4 sheets of 8.5 x 11: paper.

First, a little history on this class:

The Dollar Tree and The Scientific Method Poster

You log into Facebook, and there’s THAT friend, the grammar expert.  The well-meaning grammar cop who is on a personal mission to correct every grammar or spelling error, ever.  The friend who would bring together the programmers who created Autocorrect for a workshop.  We accept that person. We love that person, and sometimes we learn from that person.  Some of us may or may not recognize ourselves in that person. I am not that person. Oh, no. I have a far more nerdy mission.

STEM ?

STEM?

STEM?

I’ve been pretty amused by the mania to turn our science and math curricula into “STEM.”

My path to the science classroom was unconventional. I took my Bachelor’s degree in Animal Science from The Ohio State University straight to a chemistry lab. I used atomic absorption spectroscopy, gas chromatography, and Kjeldahl digestions to analyze everything from the protein content in alfalfa to pesticide residues in soil. I had to be creative. I had to invent things. I had to mess things up, to do things that didn’t work, and then I had to make them work. Then, I ran the quality control department in a food production facility (human, this time.) If someone had gotten sick or died from consuming our product, I would have been responsible. I got pretty good at creative troubleshooting. I left that job when our first son was born. A bit bored, I joined up with 3 other scientists and a salesman to start a company. We collected soil and crop samples from dairy and hog farmers, analyzed the samples for nutrients, and then manufactured custom fertilizer for the soils and nutritional supplements for the animals based on the feeds they grew. I remained a partner until Baby Number Last was ready for preschool. I was at work until about 4 hours before his birth. I returned to work with baby in tow when he was 5 days old. But I digress. And, by the way, was any of this STEM?

Candy 2013: A First Adventure into PBL

For years, my chemistry classes have made candy right before winter break. In years past, we spent a day investigating solutions, then I handed out a recipe and we made the candy. This year, with the blessings of  grant from NBPTS to investigate project based learning, I began to learn how to integrate content into a project. I’m working on using more true PBL instead of simply asking students to do projects. In addition to the integration of academic content into making candy, students blogged about their learning and their work. Some students worked in Evernote and when they finished, posted their work using postach.io.  Postach.io is now a paid app, and the features available for free may change before we use it again. Commenting must be done through Disqus, yet another sign-up and sign-in, so most students opted not to use it. I’m not going to lie – getting kids set up on Blogger through their school Google apps accounts was a challenge, and I’m on the hunt for something better. Next year, I will consider WordPress unless I find something better in the meantime.

EDIT: I’d love to know that information posted on the Internet is eternal. All links to student blogs and pages have been removed as they expired when students graduated.

The Paper Mill Project 2013

This post might well be titled “Adventures in Project-Based Learning.”

Students Working with Sludge

Sludge

You have to start somewhere.

It was an experience in jumping in feet first, and fortunately, also an experience in collaborative problem-solving. Based on the student excitement level, the student-initiated collaboration, and the chemistry-rich discussions involved, it was also a very successful experience.

I’ve learned that students find a final project more relevant than just a final exam. I’ve used either or both together as a final assessment.  One favorite in the past has been the scavenger hunt. Most of my Chemistry kiddos had done the biology version last year, so I wanted to provide them with a different experience in Chemistry.

Creativity and Science, Part 4

It’s been almost 2 years since we attended Learning and the Brain.

The first 3 posts are linked below.  I’ve had a while to implement some new ideas and process this topic. Anecdotal evidence from my own classroom began to show me that creativity in the secondary science classroom is different; in science, one must know something in order to create something new. I began to pay more attention to the push for creativity on social media. Here’s what I’m learning.

Creativity and Science, Part 3

From Learning and the Brain Conference, Day 2, Friday.

Souls of Pe bring water for purification.

It’s pretty clear to me, perhaps because I’m looking for it, that however one views creativity, one has to know something to be creative in a productive sense. Rigorous content is part of most models of PBL and creativity models. I’m not sure this is obvious to everyone, though. I’ve always known that before kids can create productively, they have to know something. Granted, some world problems appear to be solvable on the surface by 6th graders playing with plastic cups and sand models of water purification systems, and 6th graders should play with these things. At some point, however, rigor and expectations need to stretch. How can this be done? Read the rest of this entry »
