uture is not out there to be "discovered": It has to be invented and designed.

Learning is a process of knowledge construction, not of knowledge recording or absorption. Learning is knowledge-dependent; people use their existing knowledge to construct new knowledge. Learning is highly tuned to the situation in which it takes place. Learning needs to account for distributed cognition requiring knowledge in the head to combined with knowledge in the world. Learning is affected as much by motivational issues as by cognitive issues.

previous notions of a divided lifetime-education followed by work-are no longer tenable.

at least 45 percent of undergraduates demonstrated "no improvement in critical thinking, complex reasoning, and writing skills in the first two years of college, and 36 percent showed no progress in four years."

What good does it do to increase the number of students in college if the ones who are already there are not learning much? Would it not make more sense to improve the quality of education before we increase the quantity of students?

students in math, science, humanities, and social sciences—rather than those in more directly career-oriented fields—tend to show the most growth in the areas measured by the Collegiate Learning Assessment, the primary tool used in their study. Also, students learn more from professors with high expectations who interact with them outside of the classroom. If you do more reading, writing, and thinking, you tend to get better at those things, particularly if you have a lot of support from your teachers.

We should be very careful in thinking about whether we’re working on the right problems. If we don’t, that ties into the problem that we don’t have experimental evidence that could move us forward. We're trying to develop theories that we use to find out which are good experiments to make, and these are the experiments that we build.   We build particle detectors and try to find dark matter; we build larger colliders in the hope of producing new particles; we shoot satellites into orbit and try to look back into the early universe, and we do that because we hope there’s something new to find there. We think there is because we have some idea from the theories that we’ve been working on that this would be something good to probe. If we are working with the wrong theories, we are making the wrong extrapolations, we have the wrong expectations, we make the wrong experiments, and then we don’t get any new data. We have no guidance to develop these theories. So, it’s a chicken and egg problem. We have to break the cycle. I don’t have a miracle cure to these problems. These are hard problems. It’s not clear what a good theory is to develop. I’m not any wiser than all the other 20,000 people in the field.

I’m still asking myself the same question that I asked myself ten years ago: "What is going on in my community?" I work in the foundations of physics, and I see a lot of strange things happening there. When I look at the papers that are being published, many of them seem to be produced simply because papers have to be produced. They don’t move us forward in any significant way. I get the impression that people are working on them not so much because it’s what they’re interested in but because they have to produce outcomes in a short amount of time. They sit on short-term positions and have short-term contracts, and papers must be produced.

The field that I mostly work in is the foundations of physics, which is, roughly speaking, composed of cosmology, the foundations of quantum mechanics, high-energy particle physics, and quantum gravity. It’s a peculiar field because there hasn’t been new data for almost four decades, since we established the Standard Model of particle physics. There has been, of course, the Higgs particle that was discovered at the LHC in 2012, and there have been some additions to the Standard Model, but there has not been a great new paradigm change, as Kuhn would have put it. We’re still using the same techniques, and we’re still working with the same theories as we did in the 1970s.

Do I have First Amendment rights in school? You have the right to speak out, hand out flyers and petitions, and wear expressive clothing in school — as long as you don’t disrupt the functioning of the school or violate school policies that don’t hinge on the message expressed. What counts as “disruptive” will vary by context, but a school disagreeing with your position or thinking your speech is controversial or in “bad taste” is not enough to qualify. Courts have upheld students’ rights to wear things like an anti-war armband, an armband opposing the right to get an abortion, and a shirt supporting the LGBTQ community. Schools can have rules that have nothing to do with the message expressed, like dress codes. So, for example, a school can prohibit you from wearing hats — because that rule is not based on what the hats say — but it can’t prohibit you from wearing only pink pussycat hats or pro-NRA hats. Outside of school, you enjoy essentially the same rights to protest and speak out as anyone else. This means you’re likely to be most protected if you organize, protest, and advocate for your views off campus and outside of school hours. You have the right to speak your mind on social media, and your school cannot punish you for content you post off campus and outside of school hours that does not relate to school.

Can my school tell me what I can and cannot wear based on my gender? Public schools can have dress codes, but under federal law dress codes can’t treat students differently based on their gender, force students to conform to sex stereotypes, or censor particular viewpoints. Schools can’t create a dress code based on the stereotype that only girls can wear some types of clothes and only boys can wear other types of clothes. For example, your school can require that skirts must be a certain length, but it cannot require that some students wear skirts and prohibit others from doing so based on the students’ sex or gender expression. That also applies to pants, ties, or any other clothing associated with traditional gender roles. Dress codes also must be enforced equally. For example, rules against “revealing” clothing, such as bans on tank tops or leggings, shouldn’t be enforced only or disproportionately against girls. All students should be allowed to wear clothing consistent with their gender identity and expression, whether they identify as transgender or cisgender. This also applies to homecoming, prom, graduation, and other special school events. Schools shouldn’t require different types of clothing for special events based on students’ sex or gender identity — for example, requiring tuxedos for boys and prom dresses for girls.

Can my school discipline me for participating in a walkout? Because the law in most places requires students to go to school, schools can discipline you for missing class. But schools cannot discipline you more harshly because of the message or the political nature of your action. The punishment you could face will vary by your state, school district, and school. If you’re planning to miss a class or two, look up the policy for unexcused absences for your school and school district. If you’re considering missing several days, read about truancy. Also take a look at the policy for suspensions. If you are facing a suspension of 10 days or more, you have a right to a formal process and can be represented by a lawyer. Some states and school districts require a formal process for fewer days. You should be given the same right to make up work just as any other student who missed classes.
