Physics Education and Failures in Conceptual Understanding

For decades, physics professors in universities and colleges in the US have known there is something wrong with physics studies in their schools. Their own physics majors have a poor understanding of basic concepts in mechanics, electricity and magnetism, and quantum mechanics.

Journals like The American Journal of Physics (devoted to teaching and pedagogy at the university level) and Physics Teacher (the same for high school and lower) bring up these issues, with a variety of proposed changes and solutions both at the individual classroom level and at the higher theory-of-ed level. D. Hestenes at ASU and his colleagues have done work in this area, both in questioning the failures of pedagogy and developing some solutions. First, the problems.

D. Hestenes wrote in "What Do Graduate Oral Exams Tell Us?" (Am J. Phys. 63:1069 (1995)) of finding a quote from physicist W. F. G. Swann, in "The Teaching of Physics", (Am. J. Phys. 19, 182-187 (1950)):

"Much can be said about oral examinations for doctor’s degrees, and in my judgment not much can be said that is good. I have sat in innumerable examinations for Ph.D. at very many different universities, sometimes as a member of the permanent faculty and sometimes as a visitor. In almost every case the knowledge exhibited was such that if it represented the true state of mind of the student, he never should have passed. However, after the examination is concluded there is usually a discussion to the effect that: "Well, So-and-so got tied up pretty badly, but I happen to know that he is a very good man," etc., etc., and so finally he is passed."

Hestenes goes on to quote Swann as saying [A student] "passes his tests frequently [including graduate comprehensive exams], alas, with very little comprehension of what he has been doing."

Hestenes diagnoses the problem as this:

It seems not to have occurred to the faculty that dismal oral exams may be symptoms of a severe deficiency in the entire physics curriculum. I submit that there is good reason to believe that they are symptomatic of a general failure to develop student skills in qualitative modeling and analysis.

These general failures mean that even students who have the grades to appear to have excellent mastery of the material do not understand basic elements of the material they have "learned".

It also suggests that college students who fail to understand the material may end up there because their confusion prevents them from attaining the mastery the "good" students have.

Of course, the errors didn't just start in college. Generally speaking, proper physical intuition is lacking in students who took high school physics, even in those who did well. Hestenes writes in "Force Concept Inventory", (Physics Teacher, Vol. 30, March 1992, 141-158)

"it has been established that1 (1) commonsense beliefs about motion and force are incompatible with Newtonian concepts in most respects, (2) conventional physics instruction produces little change in these beliefs, and (3) this result is independent of the instructor and the mode of instruction. The implications could not be more serious. Since the students have evidently not learned the most basic Newtonian concepts, they must have failed to comprehend most of the material in the course. "

Hestenes et. al. wrote the Force Concept Inventory, a multiple choice test whose aim is to "to probe student beliefs on this matter and how these beliefs compare with the many dimensions of the Newtonian concept. " It poses questions that force a choice between the correct Newtonian answer for an explanation of a given system, and other commonsense explanations that are actually misconceptions. After the test, interviews are done to determine students' reasoning.

Here's an example of a misconception that the FCI aims to tease out of a student:

[The misconception of "impetus":]
The term "impetus" dates back to pre-Galilean times before the concept was discredited scientifically. Of course, students never use the word "impetus"; they might use any of a number of terms, but "force" is perhaps the most common. Impetus is conceived to be an inanimate "motive power" or "intrinsic force" that keeps things moving. This, of course, contradicts Newton’s First Law, which is why Impetus in Table II is assigned the same number as the First Law in Table I. Evidence that a student believes in some kind of impetus is therefore evidence that the First Law is not understood.

The FCI has been given to thousands of college and high school students. The above paper details the results on the FCI, given as a pre and post test to both high school and undergraduate physics courses, with tremendous detail on similarities and differences across classrooms in the country. More, it provides strong evidence that traditional college physics pedagogy isn't doing anything to teach physics to the students who take it:

"The pretest/post test Inventory scores of 52/63 for [The Regular Physics Mechanics course at Arizona State University] are nearly identical to the 51/64 scores obtained with the Diagnostic for the same course...we have post test averages of 60 and 63 for two other professors teaching the same course. Thus, we have the incredible result of nearly identical post test scores for seven different professors (with more than a thousand students). It is hard to imagine stronger statistical evidence for the original conclusion that Diagnostic posttest scores for conventional instruction are independent of the instructor. One might infer from this that the modest 11% gain for Arizona State Reg. in Table III is achieved by the students on their own. "

Which brings us back to the state of physics majors going to graduate school:

One of us (Hestenes) interviewed 16 first-year graduate students beginning graduate mechanics at Arizona State University. The interviews were in depth on the questions they had missed on the Inventory (more than half an hour for most students). Half the students were American and half were foreign nationals (mostly Chinese). Only two of the students (both Chinese) exhibited a perfect understanding of all physical concepts on the Inventory, though one of them missed several questions because of a severe English deficiency. These two also turned out to be far and away the best students in the mechanics class, with near perfect scores on every test and problem assignment. Every one of the other students exhibited a deficient understanding of buoyancy, as mentioned earlier. The most severe misconceptions were found in three Americans who clearly did not understand Newton’s Third Law (detected by missing question 13) and exhibited reading deficiencies to boot. Two of these still retained the Impetus concept, while the other had misconceptions about friction. Not surprisingly, the student with the most severe misconceptions failed graduate mechanics miserably, while the other two managed to squeak through the first year of graduate school on probation.

Is it just that the Chinese students who manage to get into US physics grad schools are such creme de la creme that they are perfect? Or is Chinese instruction vastly superior?

(And for those who wonder about American instruction in other subjects, read this and weep:)

One disturbing observation from the interviews was that five of the eight Americans, as well as five of the others, exhibited moderate to severe difficulty understanding English text. In most cases the difficulty could be traced to overlooking the critical role of "little words" such as prepositions in determining meaning. As a consequence, we discarded two interesting problems from our original version of the Inventory because they were misread more often than not.

And yet, those who make it through physics graduate school to professordom mostly correct these errors, at least in mechanics. (Though not necessarily. In quantum mechanics, new professors are notorious for teaching elements of the material incorrectly. In special relativity, David Mermin, prof at Cornell, believes many professors teach the entire subject wrong. (He discusses this in a paper called something like "how to teach Special Relativity.") Hestenes suggests this is due to the realities of post quals grad school: the day in, day out teaching and researching refine one's intuition over and over again.

I think this implies something else as well. Error correction in intuition can only occur and stick if the mastery of the manipulation of the equations is so strong that you (correctly) believe what they tell you. If you can be forced to do the math on the board, and forced to read and think about what it says, then you can learn the truth counter to what your intuition tells you, but only if you are utterly sure you did the math on the board correctly.

If instead, you doubt yourself, doubt your manipulation of equations, doubt your application of the laws as you understand them, then you will get confused, doubt your answer, default to your intuition, and scrap learning the correct way to think.

That means you need a tremendous amount of mastery. How in the world to achieve that?

Hestenes' answer --changing how physics is taught in high school and in college--will be explored in a week or so.

Richard on proof by obfuscation

re: TERC on Establishing Truth in Geometry

Oh really .... I don't know where to begin!!!!

"establishing the validity of ideas is critical to mathematics"

I know straight away that my blood pressure will need to be checked by the time I get to the end of this!!!

But wait, there's more!!!

"Most mathematics instruction and textbooks, however, lead us to believe that mathematicians make use only of formal proof -- logical, deductive reasoning based on axioms."

Of course, that should read "Most mathematics instruction and textbooks AND ALL MATHEMATICIANS ..."

"evidence for its validity in the form of a proof"

By this stage, it's pretty obvious to me that the author isn't a mathematician. "Validity in the form of a proof" ..... what other type of validity is there??

Of course, the trained mathematician should have their 'proof by obfuscation' alarm bells ringing by now.

"For a mathematician, often this internal testing can take the form of proof as one attempts to perform the socially accepted criticism of one's argument."

Is this even English? [ed.: I've been asking myself the same question. When I finally learn how to diagram sentences, I'll be able to answer it.]

"However, does proof convince students? Do they see it as a way to establish the validity of their ideas or, as Hanna (1989) suggests, as a set of formal rules unconnected to their personal mathematical activity?"

They'd better see it as (ahem) "a way to establish the validity of their ideas" or their teacher hasn't really communicated the difference between Science and Mathematics too clearly.

Worthy of mention is the desire to "convince students" .... you may accuse me of semantic nitpicking here, but it's important!!

"Ironically, the most effective path to engendering meaningful use of proof in secondary school geometry is to avoid formal proof for much of students' work."

Which roughly translates as "In order to save the village we had to destroy it!"

---------------------------------

I think Melanie Philips (British author) summed it up best in her book 'All Must Have Prizes':

"A fundamental shift in emphasis from knowledge transmitted by the teacher to skills and process 'discovered' by the child has undermined the fundamental premises of mathematics itself. The absolutes of exactness and proof on which the subject is based have been replaced by approximation, guesswork and context."

In reality, no one can teach mathematics. Effective teachers are those who can stimulate students to learn mathematics. Educational research offers compelling evidence that students learn mathematics well only when they construct their own mathematical understanding (MSEB and National Research Council 1989, 58).

TERC on Establishing Truth in Geometry

No one would deny that establishing the validity of ideas is critical to mathematics, both for professional mathematicians and for students. But how do people establish "truth"; how can they prove things? According to Martin and Harel (1989), in everyday life, people consider "proof" to be "what convinces me." Most mathematics instruction and textbooks, however, lead us to believe that mathematicians make use only of formal proof -- logical, deductive reasoning based on axioms.

But mathematicians most often "find" truth by methods that are intuitive or empirical in nature (Eves 1972). In fact, the process by which new mathematics is created is belied by the deductive format in which it is recorded (Lakatos 1976). In creating mathematics, problems are posed, examples analyzed, conjectures made, counterexamples offered, and conjectures revised; a theorem results when this refinement and validation of ideas answers a significant question. Hanna (1989) argues that because mathematical results are presented formally by mathematicians in the form of theorems and proofs, this rigorous practice is mistakenly seen by many as the core of mathematical practice. It is then assumed that "learning mathematics must involve training in the ability to create this form" (pp.22-23). The presentation obscures the mental activity that produced the results.

In fact, according to Bell (1976), personal conviction grows out of internal testing and forming a judgment about whether to accept or reject a conjecture. Later, one subjects this judgment to criticism by others, presenting not only the generalization formed but evidence for its validity in the form of a proof. For a mathematician, often this internal testing can take the form of proof as one attempts to perform the socially accepted criticism of one's argument.

In sum, formally presenting the results of mathematical thought in terms of proofs is meaningful to mathematicians as a method for establishing the validity of ideas. However, does proof convince students? Do they see it as a way to establish the validity of their ideas or, as Hanna (1989) suggests, as a set of formal rules unconnected to their personal mathematical activity?

Let me guess.

No?

No, students do not see proof as a way to establish the validity of their ideas?

Is that it?

Conclusion

Ironically, the most effective path to engendering meaningful use of proof in secondary school geometry is to avoid formal proof for much of students' work.

I had a feeling.

By focusing instead on justifying ideas while helping students build the visual and empirical foundations for higher levels of geometric thought, we can lead students to appreciate the need for formal proof. Only then will they be able to use it meaningfully as a mechanism for justifying ideas.

Dobbs Ferry adopts Singapore Math

District adds new program to Springhurst

Robyne Camp, who was elected to the board in May, has asked the district to pilot Primary Mathematics in 2 first grade classes next fall and to give parents the choice of enrolling their child in the pilot class or in a class using Trailblazers.

This passage is one to cite often:

Dobbs Ferry isn’t alone in rethinking its approach to teaching math. In recent years, there has been a shift away from more traditional methodology, including so-called “reform” math programs like Trailblazers which have drawn criticism from some teachers and parents.

National Coalition Presents "Design Principles for K-12 Mathematics Standards and Assessments" and Seeks Seat at National Standards Writing Table

The United States Coalition for World Class Math, a new non-partisan organization of concerned parents collaborating with professional mathematicians, educators, and others to promote improvements in K-12 mathematics education, has just issued its "Design Principles for K-12 Mathematics Standards and Assessments." It is also asking to be included in the decision-making process for the national mathematics standards currently being developed by the National Governors Association and the Council of Chief State School Officers in concert with several other educational organizations.

"Extraordinary numbers of grassroots groups have formed in recent years to learn more about current issues in mathematics education and to promote improvements in K-12 mathematics curricula," says Coalition co-founder Timotha Trigg. "Many parents believe there is already a crisis in mathematics education and fear that poor standards, if adopted by states on a national scale, would make the situation even worse."

For example, the most recent Trends in International Math and Science Study (TIMSS) found that only 6% of U.S. eighth grade students perform at the advanced level in mathematics, whereas 40 - 45% of eighth graders in top-performing countries reach this level. The poor performance of U.S. students on these and other state, national, and international assessments has not only spurred interest in creating national mathematics standards, it has also motivated many parent groups to unite under a single banner and to design a document setting forth their own principles for K-12 mathematics standards and assessments.

Jill Gladstone, who helped to spearhead the Coalition, states, "This document is intended to help inform the Common Core State Standards Initiative, the 46-state effort that will result in K-12 mathematics standards and assessments for public school students in participating states." Key points of the Coalition's Design Principles, found at United States Coalition for World Class Math, include:

Top-rated mathematics standards (MA, IN, and CA) should be used as a model; University mathematicians must play a key role in establishing priorities and ensuring mathematical content is appropriate and clear in both standards and assessments; and The findings and recommendations of the National Mathematics Advisory Panel, which reviewed more than 16,000 research studies, must be followed.

Gladstone adds, "Our website is generating a tremendous amount of interest nationwide. Each week, at least one new state chapter is being formed by parents who are counting on us to make their voices heard. These parents have earned a seat at the decision-making table as a core of common mathematics standards and assessments is constructed. We look forward to participating as a full partner in the effort to create world class mathematics standards and assessments for our children."

Don't Get That College Degree

Here’s an alarming article by Jack Hough from the New York Post that states:

“The four-year college degree has come to cost too much and prove too little. It's now a bad deal for the average student, family, employer, professor and taxpayer.”

It tracks two 18 year olds who both save the same amount of money (about $16,000) for college. One gets accepted to a college, the other does not. Both spend their lives making average incomes for their respective conditions; one with, and one without a college degree. Both set aside the same % amount of their respective salaries for their entire working lives. The grad uses the set aside for 12 years to pay off the loans and then starts saving at the same rate as the non-grad (who has been saving already for 16 years). The high school grad has all the saved up college money and a 16 year head start on investing a lesser amount of money each year.

At age 65, one person has accumulated savings of $1.4 million, the other just $400 thousand. Read the article to find out who the millionaire is.

Lest you think it’s just about money, read on…

“It's crass, you might think, to reduce education to a financial decision. An educated citizenry is healthier, more tolerant, more politically engaged and more fulfilled than an ignorant one. But I refer above to degrees, not education. The two are not the same, even if policymakers talk as though they are.”

Employers want a degree because it indicates to them that applicants have learned the “foundations of human knowledge” but here is a sampling of what passes for courses that fulfill core degree requirements at major universities.

“History of Comic Book Art (Indiana University), History and Philosophy of Dress (Texas Tech University) and Campus Culture and Drinking (Duke University)”

Couple meaningless core courses with grade inflation and you’ve got degrees that don’t mean anything. Employers are being suckered. Hyperinflation of tuitions in an age where knowledge is incredibly accessible for free, means students are being suckered. And last but not least, colleges spend huge amounts of time now doing remediation so parents too are being suckered for the 13 years preceding college.

The article proposes a fascinating concept, the ‘knowledge transcript’ to replace degrees. It’s sort of a tree diagram that describes all of the branches of knowledge components that a student has mastered as certified by standardized tests. It doesn't say a thing about how you got the knowledge, only that you've got it. Such a system would crush the elite college's ability to deliver crap at hyper-inflated rates.

I’d like to see knowledge transcripts in K-12 too. Maybe this is too much transparency to hope for but wow, does it make sense!

NCTE presents: Phonics Phacts

As risk-takers and decision-makers themselves, students make many choices about their own learning, within parameters established by the teacher.

Some Key Principles of a Whole Language Perspective on Learning and Teaching, courtesy of the NCTE

The writer is talking about elementary school children 'making a choice' about what materials will help them learn to read, write, do arithmetic, and learn science and history.

That's a risk, alright.


"Phonics Phacts"

under the banyan tree

from Paul:

Years ago, when I was an engineering manager, I had this Indian guy working for me. He was a graduate of IIT, India's equivalent to MIT or maybe Stanford. To qualify for IIT you have to be in the top 1-2% of applicants. He was incredibly smart and unlike a lot of young engineers he was also able to think out of the box. He could push the enevelope. Where his peers were better at just executing somebody elses plan, he could come up with the vision.

One day I asked him about his schooling. He said that except for IIT his entire education took place under a tree in the center of his village with a village elder/teacher/wiseman type of guy. I'm just guessing here because at the time I never thought to ask, but my bet is that this guy didn't go to a fancy ed school. We're not talking marble halls, olympic pools, or multimedia classrooms. There were no bulletin boards, reflections, projects, or discoveries. There was no group work, spiral curriculum, or state standards either. Just a smart man, a willing student, and the transfer of knowledge, probably not unlike what took place for the 10,000 years before we started education research.

Makes me go hmmmmmmmm?

I've been wondering for a while now whether you reach a tipping point: is there a point at which you're spending so much money on a school that quality declines?

I don't know the answer but the question relates to Gawande's article on The Cost Conundrum in medicine.

Vicky S asks:

What percentage of identified learning disabilities do you suppose is inadvertantly caused by our schools, their teaching methods, and curricula?

I've been trying to suss this out for a while now. This week I found an estimate of the percent of reading problems that could be prevented:

We estimate that the number of children who are typically identified as poor readers
and served through either special education or compensatory education programs (as well as children with significant reading difficulties who are not formally identified and served) could be reduced by up to 70 percent through early identification and prevention programs.

I have the impression that most kids identified as having learning disabilities are struggling readers but if palisadesk or Liz Ditz are around they can let us know whether that's correct.

from a longtime member of ktm, whose high school is as good as its ranking in U.S. News:

X. and I just returned from our local Barnes and Noble. Under a sign labeled "Required School Reading" were several copies of Animals in Translation. Other books on the table included For Whom the Bell Tolls, The Great Gatsby, Blink, Night, The Cannery, Of Mice and Men, Animal Farm, Romeo and Juliet (and lots more). We decided it was quite an honor to have one's book included with such famous titles.

I am thrilled!

Obi-Wan on what means 'teaching'

Personally, I find the whole thing deeply insulting.

For all the thousands of years of human existence, teaching has meant one thing, and one thing alone. 

For a few years, a bunch of hippies told us that "teaching" meant the exact opposite of that, and that we couldn't do that thing that used to be called teaching. We went through the motions of their BS while they were looking, and taught our kids the right way when they weren't.

Now, they've rediscovered teaching, think they need a new term for it, and my district thinks I need to attend a week's worth of in-services to know how to do it.

I've got two words for the whole educational theory crowd, and they ain't gonna like the first one.

Obi-Wan is a math teacher, by the by.

next time, try Core Knowledge

When it opened its doors in 2006, Philadelphia's School of the Future (SOF) was touted as a high school that would revolutionize education: It would teach at-risk students critical 21st-century skills needed for college and the work force by emphasizing project-based learning, technology, and community involvement. But three years, three superintendents, four principals, and countless problems later, experts at a May 28 panel discussion hosted by the American Enterprise Institute (AEI) agreed: The Microsoft-inspired project has been a failure so far.

wow

First Michael Jackson, now this. What a week. Who could have seen this coming?

"Microsoft chose to ... assign a team of educators and technologists to work in concert with the school system and the surrounding community to create a sustainable learning environment," said Mary Cullinane, Microsoft's lead on the project and one of the school's initial architects, in 2006.

By creating a general-enrollment school that was paid for, staffed, and operated by the public school system, project organizers aimed to create a model that could be replicated easily in other districts. (See "‘School of the Future' opens doors.")

The components of the school also were considered to be progressive. From alternative school hours to laptops for every student, from a customizable school portal to campus-wide wireless access, and from a panel to design 21st-century curriculum to a new teacher hiring model, the SOF was thought to be a sure winner.

"We naively thought, I guess, that by providing a beautiful building and great resources, these things would automatically yield change. They didn't," said Jan Biros, associate vice president for instructional technology support and campus outreach at Drexel University and a former member of the SOF Curriculum Planning Committee.

That's the difference between me and Bill Gates.

When I have a naive idea, the city of Philadelphia doesn't give me $63 million dollars to inflict it on other people's children.

Microsoft's expertise was based on what the company calls the 6 "I"s: introspection, investigation, inclusion, innovation, implementation, and--again--introspection. It was up to the Curriculum Planning Committee to design the underlying principles and goals for the school, based on this framework. 



However, these principles too often seemed unclear. 



You think?

Although the technology itself was not supposed to trump basic classroom practices, Microsoft and the school's planners had decided not to allow the use of textbooks or printed materials; instead, all resources were located online through a portal designed by Microsoft. 



Yet educators frequently encountered problems accessing the internet, because the school's wireless connection often would not work. 


"This vital part of the school's technology was never stable and robust enough to make it dependable," said Biros. "There was no safety net, and it seemed like a great leap of faith--faith that these teachers, amidst so many new circumstances, would be able to develop curriculum almost on the fly and store and distribute it electronically." 



Books are good.

Another problem was that the students--most of whom came from poorer families and neighborhoods--could not use or maintain their laptops properly. Students were either afraid to take their laptops home for fear of theft, or they didn't know how to access all the programs on the machines.

Again.

Books are good.

On another front, although Microsoft eventually sent someone to the SOF during its second year to try and foster community relationships, no one realized that school-community partnerships take time, perhaps even years, to mature--leading to uninvested partnerships with no long-term sustainability. 



I say forget the school-community partnerships and have the kids read some books. Also, math is good. You could teach kids math using a math book.

At one point during the discussion, an audience member asked: "All of your resources are online, and educators have to access [them] through this portal. However, your educators don't know how to work the technology. So, exactly what did the teachers teach in class? What were the students learning?" 



"Well, honestly, I'm not exactly sure," replied Biros. 



That's not an answer.

According to Biros, the creation of assessments was problematic. 



"We all agreed that students should be evaluated qualitatively, without customary grades and standardized tests, but we did not consider how colleges would use these assessments to determine students' acceptance into their programs," she explained.

They do what they do.

"It's been three years, only three years," said Hess. "I can't say it's a failure, and I can't say it's a success. Give it another three years, and then we'll be able to say for certain."

a definition of explicit instruction

Explicit instruction is instruction that does not leave anything to chance, and it does not make assumptions about skills and knowledge that children will acquire “on their own.”

For example, explicit instruction requires teachers to directly make connections between the letters in print and the sounds in words, and it requires that these relationships be taught in a comprehensive fashion. It also requires that the meanings of words be directly taught and be explicitly practiced so that they are accessible when children are reading text. Finally, it requires not only direct practice to build fluency, but also careful, sequential instruction and practice in the use of comprehension strategies to help construct meaning.
