Aligning Metrics for Success

Stagnation

I need to make some changes in my classroom. I feel as though class performance is stagnating. Sure, I looked at last year’s data, took many opportunities to reflect on what worked and what didn’t, and revised for this year accordingly. I pre-assess, modify, post-assess, and adjust several times a week, if not several times in the same lesson. But it seems no matter what I do, within my current comfort zone there’s still a group of students I’m just not reaching, and I’m not seeing the level of improvement in results I would hope to as I continue to grow as a physics teacher.

So what’s going on? This is the question I’ve been struggling with for several months now. This year seems especially tough. I’ve been told by previous teachers of this class of students that they require a larger push than previous classes, but there’s more to it than that. I find many of my students are more interested in chasing points and grades than they are in learning. After every exam I hear requests for “make-up” tests or points for corrections, yet preparations for the initial assessment are lacking… homework doesn’t get done, and much of the homework that is done is incomplete. Students do the problems they’re comfortable with, and skip the ones they need practice with! I’ve tried grading homework, even though I’m not a fan of “points” as a motivator. This has pushed more students into my classroom for “how-to” help the moment before the assignments are due, but instead of working to truly understand the problem, the students push hard for just enough to answer the problem and then bolt out the door. Learning has taken a back seat to point gathering.

Many who are performing better on standardized assessments come into class bragging about how they didn’t know anything, crammed for a few hours the night before the exam, and then tell their peers (in front of me) that they’ve already forgotten the material. This isn’t building true understanding, and as we all know, physics builds upon itself. It’s a holistic science that takes years to understand. A solid foundation in all the different aspects and applications provides the framework toward making the connections that will later allow for truly understanding the world around us.

I’ve incorporated more hands-on work, practical applications, challenges, authentic assessments, projects, etc. than in any year previous. We’ve built catapults. We’ve modeled motion graphs with cars, with people, by hand, with motion detectors. We’ve investigated crime scenes to understand projectile motion. We’ve analyzed car crashes to understand momentum. We’ve launched a rocket to demonstrate Newton’s 3rd Law… but for many, these activities are becoming an effort in meeting the absolute minimum requirements as quickly and carelessly as possible.

Something has to change.

I feel as though I’m assessing constantly… and in many different ways. Students are given opportunities to demonstrate their learning in a model of differentiation across both interests, current skill level, and media. Want to do your lab report as a poster? A comic book? A rap song? A Powerpoint? A video? A skit? A conversation? A written exam? Sure, why not… Up for the challenge of going a bit beyond the basic expectations? I believe in you, let’s see what you can do. Having trouble nailing down where to start? Let’s talk about goals and work backwards to help you create a plan.

It helps, but something is still missing. I’m assessing work and projects. I’m assessing based on skill and, much as I try to avoid it, effort. I’ve believed that if students put the effort in, the learning will come, and my grading style has reflected this. But students have learned the game, so to speak, and attempt to demonstrate to me a large effort, by showing a large volume of sub-standard work. I want to encourage them to make their learning meaningful. I don’t want my students spending hours and hours each night on physics. I want them engaged and focused in the classroom. I want them spending a reasonable amount of time outside of class working productively to do what they need to in order to be successful. In short, I want them working smarter, not harder.

So then, why am I assessing work? I’m a firm believer after several years in engineering and industrial management that you set up your metrics to drive behaviors. With the right metrics in place, students and employees will work to meet those metrics. I spent more than 10 years at two different companies and in four different jobs preaching this to anyone who would listen. So what happened to change my thinking when I became a teacher?

It seems so obvious when I stop to think about it… especially when my metrics are so clearly defined. I even write my objectives at the beginning of each lesson, and usually share them with my students! I organize and plan my entire curriculum around learning objectives. The objectives, the standards, the proficiencies — these are my true metrics. These are my goals. These are what I need to be grading students on, not work or projects. Where do you go next? Welcome to standards-based grading (SBG). I don’t expect this to be a fix-all utopia of physics teaching. But it’s a step toward measuring and communicating goals and expectations clearly with my students, and that has to be a strong first step.

I don’t have the answers, I don’t even have the questions. But now I at least feel as though I’m on a path to finding the right questions to ask.

Is the gravitational constant really a constant?

Scientists have been measuring the universal gravitational constant, G, for hundreds of years.  But, how accurate are they in their measurements?  Is G truly a constant?  It’s a question physicists and astronomers continue to debate.  Due to variations in experimentally obtained values for G, a number of postulates have been proposed which note that G may vary with time, and could be dependent on orientation, surrounding masses, even the curvature of space time!

Complicating matters, experimental error in the determination of G is typically estimated at 1%, even with modern measuring equipment.  Is G really a constant?  Does it vary within this +/- 1% window?  Is Newton’s Law of Universal Gravitation complete, or is there more to it?  Recent studies continue to explore and debate these questions.

Building a Web Community


My goal with APlusPhysics is to create a friendly, coherent and dynamic online resource with a consistent theme; an integrated toolset which can be easily customized to meet the needs of a diverse student and educator constituency while incorporating best known practices in physics education research. The site is designed for easy integration with physics modeling strategies, standards based grading (SBG), mastery learning, and “alternate pathway” programs which support students who, for various reasons, aren’t able to fit into the standard classroom educational model.

It’s a work in progress. I’m learning as I go, refining, expanding, deleting and rebuilding. And then doing it all over again. I’m thankful for the support of the physics community as they provide feedback, ideas, opportunities, and constructive criticism that allow for continual refinement and growth from a variety of perspectives, and whose thoughts and ideas are the foundation of this online conglomeration. I hope you find APlusPhysics a useful web resource, and this blog an insightful journal of a developing teacher’s successes, failures, challenges, struggles, and achievements.

Welcome one and all!

WHO AM I?

I’m a high school physics teacher learning something new every day. I was an engineer in industry for more than 10 years, and an adjunct college professor for eight, yet after three years teaching standard introductory (Regents) as well as AP-B and AP-C physics classes, it is obvious to me that student learning styles are changing rapidly… the standard “by-the-book” pedagogy is no longer the optimal method for teaching all students. I need to find a way to differentiate across a wide range of abilities, interests, backgrounds and habits if I want to help each of my students grow to their maximum potential in the brief time I have with them.

I don’t have all (or many of) the answers — I don’t even have all the questions! What I do have is the energy and ability to learn, make changes, take risks, succeed, fail, and ultimately, grow. This blog details my journey.


WHY GO TO THE TROUBLE?

Writing is thinking. Writing forces you to organize your thoughts, to make mental connections — analyzing what’s worked, and what hasn’t. It forces you to think through your next steps, to reflect on why your experiments succeed and fail. It helps to recognize what you do and don’t know, providing a well-lighted path toward “filling in the gaps.”

No single text or resource completely matches the way you teach. Our class text is a wonderful resource for our students, and I was even lucky enough to serve on the committee which selected the book during my second year in the classroom. It’s accurate and thorough. It aligns nicely to our district outcomes and state standards. But it’s not designed specifically to the course I teach and the method in which I teach it.

Further, students are reluctant to learn and read independently from our text. This is troubling. The most important skill I can teach my students before they leave my classroom and go on to bigger and better things is the ability to teach themselves. Empowering them as learners requires technical reading, critical thinking, and discipline. I struggle with this throughout the entire year, and each year set a goal to extend my students’ independent learning skills through guided inquiry, discovery, and practice. Still, though, in many cases, even with our text, there are gaps.


BRIDGING THE GAPS

I have embarked on a project to create my own online physics resource, tailored specifically to course objectives, with as little extraneous information as possible, and consistent with the methods and organization I use in my classroom. I’m learning and changing every day, so this resource has to be dynamic. Problem solving practice with immediate and constructive feedback should be integrated into every unit. Most importantly, students should learn at their own pace. With a tremendous span of abilities, backgrounds, and learning styles, it’s obvious that one size and speed doesn’t fit all.

Key aspects of this resource, APlusPhysics, include online discussion forums promoting discourse about concepts, applications, and new developments in science; online homework help where students can assist each other (the best way to learn is to teach!); student and educator blogs for learning logs and self reflection; course content distilled down to the “need-to-know” facts with a variety of sample problems, designed specifically to meet course objectives; built-in quizzes to allow students to test their understanding; and resources for physics instructors focusing on student-centered active learning activities.

Many of these resources can be found, in whole or in part, elsewhere on the web. The Physics Classroom is a terrific online resource covering a wide variety of topics in physics; Cramster is a terrific resource for homework help and problem solving; Physics Forums is a terrific bulletin board system discussing physics developments and problems; Castle Learning offers students a tremendous repository for problem solving practice; and of course there are many others.

I’m not trying to rebuild or re-create any of these terrific resources… they all have tremendous potential for the students who take the time to learn and use them productively. However, the learning curve for this expanse of resources can seem insurmountable to the new physics student already exhibiting the classic “deer-in-headlights” shock I’m sure all physics teachers are familiar with. This project is an ongoing method of delivering, refining, and reflecting upon high school physics education.
