New research on an old idea
Co-author: Amanda Valenti
Of the 100 or so physics professors that we (Amanda and Elissa) have met over the years,Almost everyone believes that physics should be the first science class every high school student takes.. If you ask our fellow biology, chemistry, and geography teachers, they agree: physics concepts are foundational and prepare ninth-grade students for later success in other science subjects. This article looks at: (a) why physics should come first, (b) why more schools still don't practice it, and (c) what we can do about it.
So let's start with (a) why physics should come first. This is not a new idea:The Committee of Ten proposed a first model of physics130 Years Ago For context, science classes in American high schools (unlike in other countries) are generally taught as one subject per year. In the last hundred yearsThe most common order in high school was biology first, then chemistry, then physics. this episode islargely arbitraryand possibly the opposite of what makes sense. Biology content is based on students' mental models of chemical processes and energy flows (chemistry), which in turn are based on physical and electrical interactions and energy transfer (physics). But the fundamentals of physics can be taught without relying too much on biology and chemistry. In fact, the high school physics we teach today—key topics like motion, forces, energy, and electromagnetism—was universally discovered.before the end of the 19th century, while much of the content in high school chemistry and biology classes dates back to the last 150 years.
By studying physics first, students learn to build models to explain and predict phenomena and then apply their model building skills to the sciences that follow. In contrast, chemistry and biology are too complex for students to build strong mental models without physical assumptions, and therefore students resort to memorization rather than conceptualization. As a result, chemistry and biology students who have not previously studied physics often learn their sciences in a hands-on rather than a systemic way. This prevents them from making predictions and testing them, a practice fundamental to science. (October 2021 Update: Many thanks to Mohammed Ashraf Aziz of Howard University and Barbara Dunn of the NIH for discussions that strengthened this paragraph.)
The most common argument we hearfirst against physicsis that math is too high. We strongly disagree: physical concepts go hand in hand with introductory algebra, making sense of potential meaning.dry and disorienting theme. Also, physics is a great opportunity to introduce math concepts to ninth graders. Our ninth graders learn the physical meaning of the slope of a graph, or the area under its curve, and are able to apply these concepts to countless applications in school and life. However, there is a non-algebraic mathematical concept that comes up in a typical high school physics class: trigonometric functions (used to manipulate vectors). Honestly, trigonometry is not fundamental to the basics of physics - you can remove this part of the syllabus or just teach it.SOH-CAH-TOAto their ninth-grade students. (We did both.)
So physics first is good for students: it goes well with algebra and prepares them for modeling and conceptualization in later science courses.But physics first is also good for schools.When surveying school principals, we have anecdotal evidence that offering physics first makes schools more attractive to potential students. Physics degree programs indicate that a school believes in rigorous science education beginning in grade 9 and that the school is innovative (althoughThe movement has been growing for 30 years). In states that have a standardized summative biology assessment (such asworld rulersin upstate New York), students' grades may increase when they take the tenth-grade test, both because they are older and because they took physics the year before. (Note that we have only anecdotal, not systematic, quantitative evidence so far.) Physics also creates a school community when all ninth graders take physics together, rather than relying on the science courses they took in high school to divide it up. them. in different sciences.
The next logical question is (b) why don't more schools offer physics first? About27,000 high schools in the US, only2000 first adopted some version of physics(according to the most recent data we could find).As of 2013, 84,000 US students participatedPhysics first, which accounted for only 6% of high school physics enrollment.The best people to talk to about this are our school principals, because they are the ones who design course offerings and teacher plans for their schools. We conducted a small survey of 17 school principals from the 5 boroughs of New York City. (Our next step is to expand the survey and its reach.) Two-thirds of school leaders surveyed had a background in math or science, but less than 20% of them had ever heard of physics. Not surprisingly, the vast majority of their schools started with biology, with physics, if any, being offered to Grade 12 students. When we asked principals if they thought it was a good idea to teach physics first, only a few said yes and half weren't sure. In general, they answered that they had not thought about this before.
The other main reason principals said they didn't offer physics first was that they couldn't find enough physics teachers to be effective in the ninth-grade classroom. Principals may be willing to revise their course schedules and deal with a few years of deadline stress, but only if there are teachers who are eager and willing to have meaningful experiences in a ninth-grade physics class. There are many potential first physics teachers, but our teacher preparation and professional development programs must promote this opportunity and nurture aspiring physics teachers.PhysTEC NYwork with these challenges.
We now turn to (c) what we can do about it. There are two approaches that need to be taken in parallel: getting school leaders to experience physics first and getting more people to become physics teachers first. School principals are aware of this.Access to physics classes is unfair, and counties with a high level of poverty are less likely to offer physics classes.. As teachers (especially those who teach low-income or underserved students), we can show our managers the importance of physical education and how relevant and impactful a 9th grade physics course can be. Therefore, it is up to directors to find teachers.Physics professors are in high demand.. And teaching 9th grade requires different skills and interests than teaching 12th grade. First, we need to attract more people to specific physics classes, perhaps from other courses or other disciplines. Teaching ninth grade physics is not an impossible task. In fact, there are many resources for ninth grade physics teachers, includingactive physicsit's himAMTA. It's fun and it's our favorite class we teach.
If there's a high school in your community that doesn't teach physics to all ninth graders, try asking (politely) why. Worth the try!
