The Trouble with Grading

By Joe Bower

“A mark or grade is an inadequate report of an inaccurate judgment by a biased and variable judge of the extent to which a student has attained an indefinite amount of material.”

--Paul Dressel

When I share with others that I assess my students everyday without ever grading them, the responses are often thick with bewilderment. While it is true that some congratulate me in a kind of envious tip of the hat, most teachers and parents struggle to rationalize how a classroom could even function without grading. Some like the idea - others don't - but almost no one can begin to conceive an alternative. This inability to conjure an alternative to grading scares me because nothing is more dangerous than an idea when it’s the only one we have.

Alfie Kohn (1999) writes:
There is a time to admire the grace and persuasive power of an influential idea, and there is a time to fear its hold over us. The time to worry is when the idea is so widely shared that we no longer even notice it, when it is so deeply rooted that it feels to us like plain common sense. At the point when objections are not answered anymore because they are no longer even raised, we are not in control: we do not have the idea; it has us (p. 1).
Kohn was referring to behaviorism, and yet such thought-provoking words can be used as a warning for any idea or practice we mindlessly implement.

Grant Wiggins (2012) reminds us that "when practice becomes unmoored from purpose, rigidity sets in." Reflecting upon one's beliefs can be a very productive use of time, and I can think of no better time to do so then when we have come to accept something as a given truth. When questions are no longer answered because questions are no longer being asked, it's time to pause and reflect. The mark of a true professional is one that spends just as much time asking why as asking how. Teachers can, and do, fill conferences with session after session on how we can better grade. However, the real issue with grading is not how but why (Kohn, 1994).

Below are three common reasons I have heard used to justify grading:

1. Motivation: Grades induce a kind of artificial, extrinsic motivation to strive for the reward of a high grade, or to avoid the punishment of a low grade. This view assumes we need grades to make kids learn.

2. Rank and Sort: Grades place students nicely on a fabricated hierarchy so that we can order those who are more worthy for post-secondary admissions and job placement. This view assumes grading indicates who is qualified and who is not.

3. Feedback: Grades provide students and parents with knowledge of student progress. This view assumes grades communicate to students and parents useful information.

While these three goals are common, using them to justify grading is problematic. That is, if we accept the above goals, grading is not necessarily the best means to promote the goals. Below, I discuss why grading doesn’t “make the grade” when it comes to achieving these goals.

First, we must fully grasp the chasm that exists between what science knows about motivation and what we typically do in schools. My thinking has been greatly influenced by Alfie Kohn's Punished by Rewards: The Trouble with Gold Stars, Incentive Plans, A's, Praise and Other Bribes. The first 300 pages completes an autopsy on the idea of using extrinsic manipulators to achieve compliance, while the final 100 pages of notes, references and citations drive the final nail in the coffin. The key idea I have taken from Kohn’s work is that the two different kinds of motivation, intrinsic and extrinsic, are inversely related; meaning, that if one grows, the other is likely to diminish. Because grades can only ever be experienced as a reward or punishment they, by definition, are likely to diminish a student’s love for learning.

Second, when it comes to sorting, the issue isn't that we are not sorting children well enough, rather the issue is that we spend time sorting them at all. We could be using our time and effort to help them improve. Ranking and sorting, bickering over grade inflation, rigid criteria and higher standards do little to help children become better people. As Kohn (1994) succinctly notes, “What grades offer is spurious precision, a subjective rating masquerading as an objective assessment.”

Third, reducing something as messy as real learning to a symbol, letter or number provides little useful information. Grades simply cannot help a student know what they have done well or how they could get better. Moreover, several researchers note that numerical grades can have a negative impact on student learning (Black et al., 2004; Butler, 1988; Pulfrey et al., 2011). Grading is a primitive form of feedback that is at best unhelpful and at worst harmful, and in many cases it can be argued that the best kinds of feedback actually requires the absence of a grade.

Unfortunately, myths are often more satisfying than truth. In education, we are distracted by grading. We have been distracted by grades, honor rolls, achievement, winning, losing, test scores, data...the list goes on and on.

Let's refocus.

Assessment can be simplified into two steps.

1. Gather

2. Share

At first this may sound overly simplistic and rather benign, but here's the catch: you do not need to use tests to gather information about student learning, nor do you need grades to share student progress (Kohn, 2011).

So what can we do instead?

We have to abandon our mania for reducing everything to numbers. While we should have measures for learning, they do not have to be reductionist or competitive in nature, and they certainly do not need to be multiple choice.

Multiple choice exams can be very clever but they are not very authentic. You cannot gain as much insight into what a student knows and what they can do if they are not afforded the opportunity to generate a response. Students cannot construct meaning in a preconceived bubble. For the most part, multiple choice science tests end up being glorified vocabulary exams, and I am not prepared to end a year's worth of class that was filled with investigation and thought-provoking discussion with a simple vocabulary test. That is why I break from traditional exam format for my final exam in my middle school science course.

First off, I provide my students with zero questions. Instead, I have my students select a collection of science concepts that we studied throughout the year and ask them to show their understanding. Because this assessment does not resemble the traditional rules of a final exam, I prefer to call it a project. To complete this project, I have had my students typically use Microsoft Publisher, but keep in mind any program that allows kids to use text, simple drawing tools and import pictures will do. Importantly, the project can be done on paper so technology does not need to be a barrier (See Figure 1).

This is not a “take home” project. While students can plan and collect materials outside of class, they create the project during the final exam time. My students have done this project in the gym while seated in traditional rows of desks as well as in a computer lab. When in the gym doing this by hand, I allow students to bring in a folder of their “raw materials” which could include pictures, diagrams, and paragraph excerpts. The collection of these materials and planning serve as a very purposeful way of reviewing the course concepts.

When introducing the final project to students, I make clear that I am less interested in knowing if kids
can draw the changes of state triangle and more interested in knowing what they can do with that knowledge. Rather than wasting time drawing the diagram, I would rather they spend their time sharing with me what they think of changes of state. As you can see in Stephanie's example, she brought in a picture of erosion and used it with an old saying, a description, a real life example from a previous grade and a question.

I also help the students understand that simply cutting and pasting a picture or paragraph does not show much understanding. We agree that for everything they paste on their project, they need to do something with it. This could include summarizing, explaining, sharing thoughts, feelings and opinions, making connections to other concepts, asking questions, telling stories, describing experiments, making metaphors, labeling diagrams, remembering field trips, etc.

While some may wonder about the rigor of this final project, I concern myself more with its vigor. One year, Lizzie (a grade 8 student) was the first to finish her project. She chose to write for just over an hour. Alex was the last student to finish writing - she chose to write for just over two hours. In contrast, the other students, from other classes, who were writing a 60 question multiple choice test were all done inside of 45 minutes, and many were done inside of 30 minutes. On average, that's only 30 to 45 seconds per question!

On average, my students write for about 1.5 hours while showing their understanding for 10-20 concepts. When I gather feedback from students, I hear over and over again from them that this alternative to a multiple choice test requires far more time and effort on their behalf while actually allowing them to show their learning. Students have said to me, after writing for over an hour, that they actually had fun learning from this project. When was the last time you heard a student say that they had fun learning from a multiple choice exam?

A student’s love for showing their learning is not a fire we have to light, rather it is a flame we must be careful not to extinguish. Just as curiosity is the cure for boredom, the cure for curiosity is worksheets and multiple choice tests. Only after years of schooling does children’s thirst for sharing their learning dissipate, lay dormant or die.

At this point, I would wager you are wondering how I assess this project. If by assess you mean how do I calculate a mark or grade... I don't. I've been with my students for 10 months. By the time this final project comes around, I already know all I need to know to assess their learning. And because I abolished grading from my classroom years ago, I have no grades to average anyway. There is no substitute for what a teacher can see with their own eyes and hear with their own ears when observing and interacting with students while they are still learning.

However, if you mean, “How do I observe my students' learning?”, let me address that question. I work with my students while always observing and listening. I don't labor over reducing their learning to a grade or a symbol - it's simply not a good use of my time (or theirs). While it is true that this project cannot be run through the bubble-sheet machine, we must remember not to allow our misguided obsession with counting and measuring to narrow the kinds of learning opportunities we provide children -- especially when one could argue that the most important kinds of learning are beyond measure.

Brain Rules

Here is a collection of media that can be used to work with and engage students around how the brain works. This is a part of a project focused on working with and engaging students in way that helps them make positive changes and/or informed choices in their lives.

I hope to add more content to this page. Please consider leaving a comment with your suggestions for more video, poetry, short stories, still images, quotes, music videos and lyrics, art and books.

Here are 12 videos from John Medina's book Brain Rules.

Explore each Brain Rule through illustrations, charts and video. These tutorials are designed to reinforce the concepts in the book; we recommend reading the corresponding chapter first.

Here's how I use Stickman Art to assess

Years ago I dedicated myself to drawing more with my students, so I searched the Internet for how to draw Stickmen. That's when I came across a college student's web site where they shared their stickman doodles. Here is a booklet that shares examples of how to draw stickmen doing all sorts of stuff.
Stickmen
Here is a booklet of stickmen pictures
that my students sometimes use to inspire
their projects.


Drawing is something I've never done very much of, and so it shouldn't be any surprise that I'm not very good. Because I am not very skilled at drawing, I make sure to draw in front of my students so that they see how I cope with doing something that I am not very skilled at.

I make a point of modelling patience and perseverance while drawing. I also make a point of never being ashamed or insecure about drawing. I want my students to see that I am pleasantly frustrated about learning to draw. Despite my modelling, many children are incredibly anxious about drawing in front of others. When it comes to their drawing skills, too many of them have what Carol Dweck would describe as a fixed mindset.

I provide my students with copies of the above booklet to help nudge and inspire them towards drawing something. Some kids don't need it while others are desperate for somewhere to start. For them, this little booklet of stickmen is a lifeline to doing something creative and original.

To integrate drawing into language arts, I often have my students try and draw new and challenging vocabulary that we encounter in our reading, viewing and writing.

In science, I've had students create comic strips that illustrate their understanding for concepts and vocabulary like buoyancy and density. I've often used these drawing projects as a substitute for the multiple choice tests that I used to think were necessary to assess student learning.

Here's an example of a project that two students collaborated on as a way to exhibit their understanding in science class. It was displayed on the wall as a mural in the hallway near my classroom door.

After missing a payment, the fish mafia
sent Mikey to "swim with the humans."

(Styrofoam, which is less dense than water, will float
because the particles are less dense, or crowded. It
has a low mass with high a high volume
making it buoyant)
Having children draw their understanding for what they are learning in school can provide them with the opportunity to create something from scratch that is their very own... or we can have them fill in 1 of 4 bubbles...

Unfortunately, I have to admit that some children would rather opt out of having to engage in doing something creative in favor of filling in a bubble sheet -- instead of seeing this as a learning style to be accommodated, I see this as a problem to be solved.

And stickmen are a great place to start.

Scantrons for Science

Dave Martin's witty post on Why we really do need scantrons finished by inviting others to share creative ways scantrons could be used to support real learning. Craig left this brilliant comment:

Drop a scantron off the school and time how long it takes to drift down to the ground. Next, poke all the holes out of the scantron sheet and re-time. Do you the holes make it fall faster? Slower?

Science labs are messy

I was reading an article from The Palm Beach Post called "Science teachers at Loxahatchee middle school strike back against hands-on labs, but I could have sworn I was reading America's Finest (and funniest) News Source, The Onion.

Apparently science teacher Greg Loumanis is "insulted" by some of the hands-on learning activities that are suggested to science teachers.

Why is he insulted?

According to Loumanis, he is a "data-driven" teacher who finds hands-on science experiments both inefficient and messy, so his science department at Osceola Middle School in Loxahatchee opted to get rid of hands-on science labs in their classrooms.

What data has convinced these educators to abolish hands-on science labs?

Test scores.

Since Loumanis convinced a couple colleagues to throw lab activities "out the window"in 2008 in favor of watching videos and Powerpoint lectures, they've experienced significant rises in standardized test scores.

Another common problem educators face is that they are inundated with a pre-fabricated, content-bloated, top-down mandated curriculum that is a mile-wide and an inch thick, and encourages teachers to cover  everything at break-neck speeds while uncovering almost nothing. This is precisely what Howard Gardner is referring to when he says:
The greatest enemy of understanding is coverage.
I thought reading about a science teacher who abolished hands-on labs experiments was weird enough, but then I read this quote from a professor of psychology named David Klahr:
There's little evidence to support hands-on learning.
Upon reading this, I was stunned -- I had no idea how anyone with any kind of education, let alone a psychology professor, could make such a claim, but then I realized what Klahr might have meant:
There's little evidence to support hands-on learning as the most efficient way to get through a curriculum while simultaneously raising standardized test scores.
Near the end of the article, it is made clear that there are systemic pressures being placed on teachers from outside the classroom that affect their teaching, including increased emphasis on test-based accountability, pacing guides, and merit pay.

When teachers are under intense pressure to teach specific content in a specific way with their salaries married to student test scores, it should be no surprise that teachers feel like the only tool they have is a hammer and every kid looks like a nail.

While it's true that educators who have come to see hands-on learning as a messy, inefficient inconvenience have lost the plot, it's important to realize that these educators tend to be the product of an education system that has come to see student achievement as nothing more than high scores on bad tests.

In this case, the goal is as misguided as the method, and school becomes a massive exercise in missing the point.

I thought David Wees summarized this entire mess up nicely when he tweeted:
If you measure understanding of science using only tests, you don't need to use labs.
If this is true, is the logical conclusion to challenge the labs or the tests?

I don't care what anybody tells me...

Saying "I don't care what anybody tells me..." is a conversation ender.

Rather than inspiring a rich dialogue around how we can improve, it further polarizes the professionals who need to collaborate, and will only encourage us all to further entrench our defensive positions.

Saying "I don't care what anybody tells me..." is really just another way of putting your hands over your ears and yelling "La la la la la".

For those who are are permanently married to their preconceived notions about how the world works, it's important to remember what Robert Pirsig once said:

The real purpose of the scientific method is to make sure mother nature hasn't misled you into thinking something that you don't actually know.

Here's how I teach variables in science

Here's one way I use to teach students about variables in a scientific experiment.

Because I believe in teaching students with projects or problems that are in-a-context and for a purpose, I needed to come up with something other than worksheets or direct instruction for teaching kids about responding, controlled and manipulated variables.

So, I wrote this fictitious research report and had the kids read and think about it:

Teachers' Institute of Action Research
Recommendation
After a yearlong study of students, it is our recommendation that grade 6 students be assigned 3 hours of homework per night with an additional 5 hours of homework on the weekends. 
Details of our Study
Our conclusion is based on an experiment conducted on students from Red Deer, Alberta. These students were split up into two groups. One group consisted of twenty grade 6 students while the other group consisted of twenty grade 12 students. 
For one year, each grade 12 student was assigned 3 hours of homework every night and 5 hours of homework on the weekend while the grade 6 students were assigned no homework. At the end of the year, both groups were given the same test based on math, social studies, science and language arts. 
The grade 12 students scored very high on the test, but the grade 6 students scored very low. 
Our research clearly shows that homework is necessary to make students smart.

Before I print this report, I modify the margins and double space the text to give students more space to show their thinking. Here's what it looks like:

Teachers' Institute of Action Research

For more on how I encourage them to show their thinking, check out this post. Basically, I have them record their thinking in the margin while they read. I encourage them to ask questions, make metaphors, share comments, express feelings, record memories and draw diagrams. 

During our class discussion, I had the kids share their feelings on the report. Everyone was critical of the study, but for different reasons. Some were emotional about it and thought evenings and weekends were better used for family time, sports or other personal interests - while others used logic to criticize the experiment's lack of fairness. 

For example, Terry thought that the experiment should be redone but this time only comparing grade 6 students to other grade 6 students. But even then, he wondered how the kids would be chosen - one group might be more intelligent and greater skilled than the other simply by accident. 

Jake questioned the experiment by wanting to know the difficulty level of the final test. As a class, we agreed that the report really didn't specify this - even though it would be important to know such information. I was pleased to see the kids reasoning that it is in fact their right to demand more information than the report offered.

When I asked the kids for the responding variable in this homework experiment, Lilly thought it was the report's last sentence "Our research clearly shows that homework is necessary to make students smart." This led to an interesting conversation about the difference between the responding variable and the conclusions drawn from the results. The kids had a hard time differentiating between the these two ideas.

The next project is for them to write up a fictitious study, as I did, and find creative ways to make the study fair or unfair. Then we will read each other's studies to see if we can identify how the variables may or may not have been designed appropriately.

Alternatives to multiple choice science tests

I have blogged about alternatives to multiple choice reading comprehension tests and now I want to offer an alternative to multiple choice science tests.

For the most part, multiple choice science tests end up being glorified vocabulary exams. I'm not prepared to end a year's worth of class that was filled with cool experiments and thought provoking discussion with a vocabulary test that asks students to fill in bubbles.

For my grade 8 science final exam, I break from traditional exam format. Step 1: I provide the students with zero questions.

I have my students select a collection of science concepts that we studied through out the year and ask them to show their understanding. Here is a sample from Matthew:

Matthew Science

Here is a sample from the example that I created:

Teacher Exemplar

Because this project does not resemble the traditional rules of a final exam, I prefer to call it a project.

To complete this project, I have had my students typically use Microsoft Publisher, but keep in mind this project can be done on paper too. Here is a hand written sample from Stephanie's project:

Stephanie Science



Last year, my students did this project in the gym while seated in traditional rows of desks. I allowed them to bring in a folder of their clippings which could include things like pictures, diagrams and paragraph excerpts (the collection of these clippings serves as a very purposeful way of studying) I'm less interested in knowing if kids can draw the changes of state triangle or even recognize it, and more interested in knowing what they can do with that knowledge. Rather than wasting time drawing the diagram, I would rather they spend their time sharing with me what they think of changes of state. As you can see in Stephanie's sample above, she brought in a picture of erosion and paragraph on states of matter and then filled the page with her thoughts, ideas and understanding.
As a class, we decided that on its own cutting and pasting a picture or paragraph does not show much understanding. We agreed that for everything they paste on their project, they need to do something with it. This could include summarizing, explaining, sharing thoughts, feelings and opinions, making connections to other concepts, asking questions, telling stories, describing experiments, making metaphors, labelling diagrams, remembering field trips, etc.

Last year, Lizzie was the first to finish her project. She chose to write for just over an hour. Alex was the last student to finish writing - she chose to write for just over two hours. In contrast, the other students who were writing a 60 question multiple choice test were all done inside of 45 minutes, many were done inside of 30 minutes. On average, that's only 30 to 45 seconds per question...

On average, my students write for about 1.5 hours while showing their understanding for 10-20 concepts. When I gather feedback from students, I hear over and over again from them that this alternative to multiple choice tests, while less stressful, requires far more time and effort on their behalf while actually allowing them to show their learning. I've heard with my own ears students say to me, after writing for over an hour, that they actually had fun learning from this project. When was the last time you heard a student say that they had fun learning from a multiple choice exam?

A students love for showing their learning is not a fire we have to light, rather it is a flame we must be careful not to extinguish. Just as curiousity is the cure for boredom, the cure for curiosity is worksheets and multiple choice tests. Only after years of schooling does a kids thirst for sharing their learning dissipate and die.

If I were to stop now and ask if you had any questions, I would bet the farm you are all wondering how I assess this project.

If by assess you mean how do I calculate a mark or grade... then no, I don't. I've been with my students for 10 months. By the time this final project comes around, I already know all I need to know to assess their learning. And because I abolished grading from my classroom five years ago, I have no grades to average anyways. What we see with our eyes daily is more important than what students bubble in on one day of the year. To fully understand my perspective on grading, I suggest you take a look at this page of blog posts.

If by assess you mean how do I observe the students' learning... then yes, I do. I work with my students while always observing and listening to their learning. I don't labor over reducing their learning to a grade or a symbol - it's simply not a good use of my time. While it is true that this project cannot be ran through the bubblesheet machine, we must remember not to allow our misguided obsession with counting and measuring to narrow the kinds of learning opportunities we provide children, especially when it is easily arguable that the best kinds of learning are in fact immeasurable.

If we are to design authentic learning enviornments for students, we must resist the urge to alter our focus from the learner to the teacher too quickly. Asking how something might be properly assessed is not a bad question, but if it dominates our thinking, we may justify not providing students with projects that they would love to do and love to learn from, but hard on us to assess. If we are not mindful of all this, assessment, ironically, can become a sabateur of learning.

Remember that no project or exam is the end-all-be-all for assessment. Could you imagine the size and complexity of a project or exam that actually assessed all a student had learned in a year? It's important to remember that the best any project or exam can do is provide a sample of the student's learning at that particular time.

This alternative to multiple choice exams provides my students and me with a far more authentic sample of their learning. Next year, I plan on going even further and have my students actually perform a series of experiments or projects to exhibit their real learning. How will I assess that? I will work with my students while always observing or listening.

Remember, friends don't let friends grade, but they do let them learn.

Grades are Distracting

In grade 8 science, we are learning about life. We are examining animal cells, plant cells, human body systems, diseases and anything else the students feel like learning about. They have a lot of autonomy and choice in selecting what they want to learn about.

Some students are learning about Leukemia while others learn about the organelles that make up the cell. Sarah approached me and asked* if she could do a poster project showing what she can learn about breast cancer. I said, "that's up to you."**

She began her research and poster during class, and come lunch she asked me if she could work on her project during her lunch hour. Again, I said, "that's up to you."

As she continued to glue new information on her poster, she turned to me and asked something very peculiar. "Mr. Bower, will I get an A on this?"

This was very odd because it was March, which means she hadn't recieved a grade from me on any project for six months.***

Another student overheard Sarah's question and replied, "Why are you asking Mr. Bower that? You know nothing is for grades!"

I too looked at her in confusion and said, "Why are you asking me if your project will get an A? You know I won't grade it."

I asked, "Why are you doing this poster?"

She look perplexed and said, "I want to get an A."

I asked her to stop working on her poster so I could ask my next question, "Sarah, why are you really doing this poster?"

She stopped and looked at me. She started to tear up a little, and said, "my aunty has breast cancer."

I was moved by her honesty and sincerity. It was very clear to me that she cared deeply for her aunty. I said, "Sarah, I couldn't think of a better reason for you to do this poster project. You do this poster and share it with your aunty."

Two days later, Sarah and her mom came in for student-led portfolios. I started to share this story with Sarah's mom when she started to cry. Then Sarah cried. I didn't cry, but I was close. Her mom shared with me that Sarah was reading more at home and showed more interest in learning than in past years.

Honestly, I can not think of a better reason for Sarah to learn about breast cancer. And yet, if I graded students, this whole experience might have ended when she said she was doing this poster to get an A. Another teacher might have smiled and thought to themselves good for you, Sarah. You are such a good little student.

Can you see how ultimately distracting grades can be? They run interference on our motivation and learning all the time. We owe it to our students and our own learning to abolish grading as much as we possibly can so all students can find more authentic reasons for learning.

If you give grades, and your students are uninterested or disengaged, might it be because they are searching for a more intrinsically motivating reason to give-a-shit? It's easy to blame the kids, but it takes more than a little guts to look at our own practices and make changes to how we have done things for so long.

I could choose to use grades in order to artificially induce my student's learning, but to be honest, I'd rather help them find a real reason for learning.

Grades seem so utterly uninspiring compared to Sarah's reasoning. I abolished grading 5 years ago, and I won't ever go back. When will you?

For more on abolishing grades check out this page.

*Yeah, that's right, my students ask me if they can do projects - no, they aren't freaks - rather, their intrinsic motivation is a by-product of the autonomy and extrinsic-free learning environment that I provide them with.

**You'll notice I didn't give her permission. You see, I don't want to say 'yes' or 'no'. I want my students to make decisions without having to look to me for permission to learn. It's a slow and painful process to wean them off of the "teacher's teet" but it's a worthy endeavour as I begin to see them make decisions about their learning because they feel ownership over their own learning. It's damn cool!

***The only time my students ever receive a grade from me is on their report card. In March, they receive their second of three report cards. It is possible that this latest 'hit' knocked Sarah off the 'bandwagon' and might explain her 'relapse'. Remember, friends don't let friends do grades.

Follow Instructions vs. discovery

What rubric did Frederick Banting follow when he discovered insulin?

What blueprints did Larry Page and Sergey Brin read when constructing Google?

What mandate did Gutenberg adhere to when he invented the printing press?

Now, I'll grant you that each of these people received some kind of guidance and mentoring by others. Each of their inventions were influenced in some way by some other product or idea. However, each of their ideas were in some way unique and creative. They each had to divert from the status quo.

Also remember that often really cool things, like bubble wrap, were invented unintentionally.

We do a disservice to our students when we make science more about following instructions and formal write-ups than about playing and discovery.

Learning vs. Achieving

It takes an a extraordinary educator to understand that learning and achieving are not the same thing, and this understanding can go a long ways in arguing for the abolition of grades.

When my students conduct science experiments in class, they do so with the understanding that the number one priority is that they learn. Whether they actually produce a successful, working experiment is entirely secondary.


Here's an example:

My students were planning and conducting buoyancy experiments. One group wanted to make a brick float inside a large plastic tub. They figured they could add oil to the water to make it thicker and therefore more dense - and this would help them make the brick float.


This line of thinking is flawed in a couple ways. Firstly, density and viscosity are two different concepts - a fluid with a high viscosity does not guarantee that it will have a high density. A real life example: oil is more viscous than water but water is more dense; therefore, adding oil to water will actually reduce the average density of the fluid, making it harder to float the brick.

After about 15 minutes of experimenting, the students figured out that something was wrong with their idea. I had been observing all the experiments, including this one, without interfering - however, class was almost over and I wanted to help this group learn from their mistakes.

After a 5 minute discussion, and some guidance from me, my students understood viscosity, density and buoyancy quite well, but that didn't change the fact that their experiment looked like an utter failure. They had a hell of a mess to clean up.

In a traditional classroom, the teacher may have judged their final product as a failure. The irony is that this group, despite their lack of achievement, may have learned more about buoyancy than the groups who did get their brick to float.

I use this experience all the time to show how students can achieve or produce very little while still learning a lot. Needless to say, when it came to assess these students, I had to report that they had a very strong understanding for the science concepts we were focusing on - even though they had nothing but their learning to show for it.
