I nevur Make misteaks.


My third year, my tenth year, and my eleventh year.


The third year was by far the worst incident of the three. About 20 minutes before the kids arrived, I turned on all nine sinks and sat down to get some work done. (Science teachers in my school had to do this every couple of weeks to keep some foul smell from making its way out of the drains). The sound of nine running sinks filled the room - loud, although somewhat relaxing. After about 7 or 8 minutes, I got up from my desk to shut them off...

My tenth and eleventh years involved incidents nearly identical to each other. A new project-based curriculum involved 7th grade science students growing basil hydroponically - without soil. (Pretty cool - learn more here). Plants were to be suspended in nutrient solution, which would flow from tank to tank via pumps. Anyway, I helped one of our 7th grade teachers set up her pumps just in time for her first class of the day...

Those were the three times I flooded classrooms.

The tenth and eleventh years were minor, as far as floods are concerned. They were cleaned up in a matter of minutes, although there were kids in the room both times. My third year was a very different story. Unbeknownst to me, a couple of the sinks had paper towels left in them, which clogged the drains. That year, I didn't flood one classroom - I flooded two. Mine was cleaned up and ready to use that day. The one below me was out of commission for about a week. (Did you know that ceiling tiles fall down, one by one, when soaked with water?).

I like to tell stories like these at the start of the school year.
"Hey kids, don't worry if you make a mistake in here. Listen to this."

Planning for Learning: A How-To

Bored Woman Studying
Middle school teachers have a special job.

I've discussed some of this in earlier posts. We have to wade through all of the middle school stuff and somehow facilitate 30 twelve year-olds in learning a new and specific concept or idea every day. In my 12 years teaching and observing (formally and informally) middle school teachers, here are four things I've learned.



1. Start with an OBJECTIVE!
I can't stress this one enough. While I like to allow for differences in style, objective-based planning is the only way to plan. You start with an objective - a measurable learning outcome that students need to know or be able to do by the end of the class. For newer teachers, this changes what can sometimes feel like the need to fill time into the need to have students learn within a limited time

Let's take as an example:
Students will be able to describe motion of particles in three phases of matter.

   -Specific? Yes.
   -Kid friendly? Yup.
   -Measureable? Sure.

Ok, we're ready to get to work.



2. Plan for Mastery
Now, the challenge is set. You, the teacher, have 45 (or 47, 50, 60, etc.) minutes to have every student meet your objective. In our example, this means you have 45 minutes for your students to learn and demonstrate a mastery of particle motion in three phases of matter. 

How in the world will you do it? If you're asking yourself this question, you're off to a great start. You've successfully changed your focus from filling time to using time. Answering this question is the reason you get a paycheck - this is your job. You are an expert in getting kids to learn. Not only that, but you need to continue to get better at it.

This step involves...
  • Planning Activities
  • Preparing Materials
  • Preplanning Questions (yes, preplanning) 

    and synthesizing everything into a smooth, focused lesson!


This is not to say that you need to do it alone! Hopefully, you have a strong, collaborative staff to help you. Discussing lessons with peers, asking others for feedback, and reflection (alone and in groups) are powerful tools that will foster improved teaching and learning.



3. Frame the Learning
The importance of framing is never better demonstrated than when seen from the student perspective. (Newer teachers, I urge you to seek out peers who excel at this and watch them in action)! This is an extremely powerful learning tool. Framing of learning involves explicitly communicating to students what they need to know or be able to do by the end of class.
In addition, it may involve...
-Explaining how you're going to help them get there. 
-Activating prior knowledge.
-Asking a question to help students begin to explore the topic.

In our example, this could be as simple as saying, "Please take a look at your objective. Today, by the end of class, you need to be able to describe how particles move in three different phases of matter. Are there any questions of what is expected of you by the end of class today?"

To me, this is so important that I use anywhere from 1-5 of my 45 minutes covering it each day. It may not sound like much, but 5 minutes is 11% of the time students have in class.
It's worth it - every day.



4. Summarize the Learning
Ok, you've set an objective, framed learning for students, and planned and implemented a lesson for mastery. 
DO NOT let the lesson simply end with the bell - end the lesson purposefully by summarizing the learning with which students should be walking away!

Like framing, the power and importance of a good summary is most easily visible from the student perspective. Opening and closing the learning both work to focus students on the objective, and are well worth the time they require.

This blog post is by no means  meant to be comprehensive. The art of teaching takes years to develop, but I am a strong believer in the four ideas presented above. After observing them in action and consistently utilizing them myself, I feel safe telling you that they  
improve student learning.

I am a Sucker

I took a note the other day.

It doesn't happen often.
I don't know if that means that there aren't many kids passing notes, or if it means that they're way better at passing them than I am at spotting them. Either way, it doesn't happen often. Maybe four or five times a year.

But this note was a special one. The receiver REALLY didn't want to give it up. And this was a good kid. A rule-following kid. As I walked towards her, she quickly stuck both hands under her desk, confirming that she had the note. I stuck my hand out.

"Give it to me, please."
"What?"
"Give it to me, please."
"Give what?"

We were off to a great start. Normally (which I guess means the three or four other times per year), after the second, "Give it to me, please," the student presents a defeated face and hands the note over. I then stick it in my back pocket and forget about it until I'm emptying my pockets when I get home. But this time, she didn't.

"The note that's in your hand. Give it to me, please."
"What note?"
"The one that's in your hand." 
(Blank stare).

By now, my interest is piqued. This is a special note. Something she really feels she can't give to me.

"This will be much worse if you don't give it to me. Please give me the note."
"She gave it to me," pointing to her friend. So much for loyalty. 
"Give me the note, please."

Finally, it ends. I get the defeated face, and I'm presented with the note. 
I put it in my back pocket, as usual. And, as usual, by the time class ends, I forget about it.

Until I get home and empty my pockets.
I reach into my back pocket for a pad of sticky notes I had also forgotten about, and I feel the note. 

It is time.

I de-crumple the note. It's really small, written in pencil, and a little smudged after its day in my pocket. I can barely read it, but I hold it close to my face and decipher:

I will bring Just Dance and Just Dance 2 for Wii. It will be a great party! 

I am a sucker.

Gross! (and Awesome) Lab

One of the messiest, grossest, and BEST labs that I have - Oobleck!

With very simple materials, students can create this strangely behaving non-Newtonian fluid. It acts like a liquid when handled slowly, but solidifies when handled quickly! (I usually use it in my middle school classroom to teach about atomic/molecular motion in solids and liquids).

A day or two day ago, I uploaded the lab to my Teachers Pay Teachers store.
(See it here - there's a free downloadable preview).

Due to some curriculum and grade level changes, I haven't had the opportunity to do this lab with my classes in a couple of years, but looking it over reminded me what a great learning experience it is - I've had kids come back to me years later and still remember it.

Below are some videos (not of me or my class) showing Oobleck's strange behavior. 
Think you know how it works? The first three comments on this post get the lab and key for free! (Please leave your email address in the comment, or email it to me separately if you'd prefer).

Cool Science Tricks

Today, I wanted to share some of the cool science that my class has been doing. 
(Although these particular videos aren't from my classroom, they showcase the science).
Enjoy!



Egg in Vinegar
When the egg is dissolved in vinegar, the shell dissolves, but leaves the inner membrane in tact. Besides being cool in general, it's a great example of diffusion - Certain fluids (and small solids) can pass through the membrane.





"Blowing Out" a Candle
When baking soda and vinegar are mixed, they create and invisible gas - carbon dioxide gas (the same stuff you breathe out). This gas is denser than air, and can be poured just like water. 






Decomposition of Water
Electric current breaks water into hydrogen and oxygen gas! The salt is to help the mixture conduct electricity. (A lab similar to this is available in my Teachers Pay Teachers store). 


 

Please share any cool or interesting science from your class!
