Convincing Reluctant Teachers

This question was posted to Twitter today:

Question: how do you convince teachers who are ADAMANT that they teach to the rigor required by CCSS that they really don’t?

(CCSS means Common Core State Standards)

This is a great question. I think it applies to a wide range of situations. You can replace “CCSS” with the Next Generation Science Standards, the new AP Physics 1 and 2 course, or any curricula du jour. It all boils down to showing these teachers that traditional teaching methods do not lead students to a deeper understanding of the concepts.

Some folks may suggest showing the reluctant teachers sample test questions from the new assessments. I say stay far away from that. These teachers will likely look for tricks to game the assessments so students can be successful without the in-depth understanding these teachers think they are teaching.

My suggestion is to have the reluctant teachers administer a basic conceptual diagnostic test to their students. The questions are so basic, so easy, the teachers will say “Of course my students can ace this!”

And then wait for the results to come in.

In all likelihood, the students (on average) will do poorly. Amazingly poorly. Even worse than if they had simply guessed randomly.

To which the reluctant teacher responds, “What happened? They should have known all this!”

Now’s your chance. I think now they’ll be more receptive to what you have to say about how students learn math and science and why interactive engagement techniques work.

Here’s Erik Mazur (Harvard physics professor) explaining what happened when he gave his students a conceptual diagnostic test:

(The video is an excerpt from Mazur’s longer “Confessions of a Converted Lecturer” talk.)

Extensive lists of concept inventories can be found at FLAG and NC State. Remember, many of these tests have been painstakingly developed and refined by researchers. Be sure to abide by the developers’ rules with administering the tests to students. You should not post them to the internet or discuss the answers with students.

You Are What You Assess

I found this near the copy machine yesterday while I was running off end-of-quarter reassessments. It was a wakeup call to the disconnect going on between what I value and what/how I assess in my own classroom.

Physics Teaching 2.Uh-Oh

My first talk! Given at the STANYS 2011 Physics Breakfast on November 8th, 2011 in Rochester, New York

A huge thank you to Gene Gordon for inviting me to speak at the breakfast. It was great to share my passions and meet my virtual colleagues face-to-face!

I’d love any feedback you have, positive and negative. Thanks!

Grading and xkcd

Today’s xkcd comic nails the problem with averaging customer ratings. The connection to grading is pretty obvious.

Couple this with parachute packing:

And do we really need anymore reasons to convince people we need to switch to Standards-Based Grading?

Also see these two articles from ASCD (in case blog posts don’t fly with your audience):

Khan vs. Karplus: Elevator Edition

Exhibit A: Sal Khan on elevators


Exhibit B: My students on elevators
Framed around the Karplus learning cycle (Exploration, Invention, and Application) my students construct the conceptual and mathematical models themselves.

1. Exploration Phase:

2. Invention Phase: 

  • Draw a motion diagram for the object attached to the scale when the scale is stationary, then being pulled up and then stops.
  • Draw a force diagram for the object attached to the scale when the scale is stationary, then being pulled up and then stops. Decide whether the force diagram is consistent with the motion diagram. How is the force diagram related ot the reading of the scale?
  • Use the force diagram and the idea under test to make a prediction of the relative readings of the scale.
  • Observe the experiment and reconcile the outcome with your prediction.

(Video and questions for this phase taken from Eugenia Etkina’s awesome site Physics Teaching Technology Resource which has many more video experiments.)

3. Application Phase:

Instead of showing our students a better lecture, let’s get them doing something better than lecture.

My Teaching Conditions Are My Students’ Learning Conditions

As a science teacher, I need my union to ensure I can do my job properly and give my students the best possible learning experiences.

My union ensures I am evaluated fairly.

I use inquiry methods with my students whenever possible. They devise their own experiments, collect and analyze their data, and share their results with the rest of the class. We problem solve on whiteboards. Students must construct their own knowledge. My students are frequently talking and moving around.

However, these methods are sometimes met with resistance from parents, students, and even some administrators. By having a fair and standard evaluation system which was negotiated by my union, I know that I am an effective teacher.

My union ensures my students are safe.

Class sizes in science are capped at 24 students. I can effectively manage the transitions from whole class discussion to small group discussion to laboratory work. Students are not overcrowded in lab. I can easily and efficiently monitor the progress of all the lab groups.

My union ensures my students are assessed in a variety of meaningful ways.

With 24 students maximum per science class, and a maximum of 5 sections, I can assess my students’ understanding in more meaningful and authentic ways. I can give my students timely feedback. I can implement standards-based grading without it becoming a bear.

My union ensures I grow professionally — and I help my colleagues grow, too.

We have options for professional development — time for self-directed PD during staff days, the ability to offer after school courses to my colleagues, the option to take graduate courses on campus or online. It is only through continuous reflection and growth that I become a better teacher.

I support my union because without it, there would be 50 students in each of my classes sitting quietly in rows, reading their textbooks (instead of doing labs) in preparation for their next multiple choice exam which will be graded by the Scantron machine.

SBG: Keeping Track of it All

“How do you keep track of everything in your standards-based grading system?”

Both the students and I are responsible for tracking scores. Here’s how it works.

My Google Docs Gradebook

I use Google Docs for my SBG gradebook. Since each course I teach has different standards, I have a separate file for each course. Multiple sections of the same course are in the same file. Here’s how the files are set up:

[1] Each assessment has its own sheet in the gradebook file.
[2] One column for each standard on the assessment, in order of appearance (question order). This makes transferring scores from quiz paper to gradebook much easier. Even easier if the quiz papers are alphabetized.
[3] Cells have color-coded formatting rules. I can easily see that everyone rocked standard BF.1, while CV.4 will need reteaching. Student A did well on the whole, while Student Y should come for extra help.

Once the scores for the assessment are recorded, I copy/paste them to the master sheet.

[4] The master sheet keeps track of the most recent scores for all of the standards.
[5] The standards are ordered by level. This make determining quarter grades easier. (See my grading policy sheet below.)
[6] The columns from the most recent assessment (in this case BF Quiz 2), are copied from the assessment sheet and pasted to the master sheet, one-by-one. Most recent scores replace old scores.

The master sheet allows me to see at a glance where everyone currently stands. (You cannot do this with the SnapGrades online gradebook.) I can see the date and assessment name for when each standard was last scored. And since each assessment has its own sheet, I do not lose the prior scores for the standards. The scores for students who reassess on their own time are entered directly into the master sheet and are annotated.

What I cannot do is see, at-a-glance, a student’s progress over time for each standard. This is why I also have…

Student Learning Folders

Each student has a 2- pocket folder with prongs. The prongs hold hole-punched pages. The first page explains my SBG grading policy.

The subsequent pages in the folder are tracking sheets for the learning goals.

When students get a quiz back, they record the name of the assessment, the date, and their scores on the corresponding standards on the tracking sheets. Students can store the quizzes in the pockets, if they wish. With their folder, students can easily see, at-a-glance, their progress on each standard over time. According to Marzano, student gains are higher when students track their progress.

At interims and end-of-quarter time, students fill out a progress report. They take the most recent score for each standard and record it under the corresponding level. This makes it easier for the student to determine their grade for the interim or quarter. Folders and progress report sheets are sent home to parents.

I then meet with students individually to discuss their grade, making sure my Google Docs gradebook reconciles with their progress report sheet.

This system works really well for me. While there are more scores to enter for each assessment, it takes the same amount of time as it would to tally up all the points earned if the quiz was scored traditionally.

Be sure to read “Improving the Way We Grade Science” for more background on standards-based grading. (It’s where I picked up the tip to color-code the scores in the spreadsheet.) You can also check out my SBG bookmarks at http://bit.ly/SBGlinks.
