For instance, how often do most adults encounter a situation in which they need to solve a quadratic equation? Do they need to know what constitutes a “group of transformations” or a “complex number”? Of course professional mathematicians, physicists and engineers need to know all this, but most citizens would be better served by studying how mortgages are priced, how computers are programmed and how the statistical results of a medical trial are to be understood.

Imagine replacing the sequence of algebra, geometry and calculus with a sequence of finance, data and basic engineering.

Traditionalists will object that the standard curriculum teaches valuable abstract reasoning, even if the specific skills acquired are not immediately useful in later life. A generation ago, traditionalists were also arguing that studying Latin, though it had no practical application, helped students develop unique linguistic skills. We believe that studying applied math, like learning living languages, provides both useable knowledge and abstract skills.

In math, what we need is “quantitative literacy,” the ability to make quantitative connections whenever life requires (as when we are confronted with conflicting medical test results but need to decide whether to undergo a further procedure) and “mathematical modeling,” the ability to move practically between everyday problems and mathematical formulations (as when we decide whether it is better to buy or lease a new car).

more efficient way to shepherd students through basic general-education requirements—particularly those courses, such as college math, that disproportionately cause students to drop out

That fall, with little debate or warning, it placed 4,700 students into computerized math courses. Last year some 50 instructors coached 7,600 Arizona State students through three entry-level math courses running on Knewton software. By the fall of 2014 ASU aims to adapt six more courses, adding another 19,000 students a year to the adaptive-learning ranks.

Petabytes allow us to say: "Correlation is enough."

There's no reason to cling to our old ways. It's time to ask: What can science learn from Google?

We have to keep developing our capabilities and avoid falling behind.

no matter how well prepared people are in their formative years, few can achieve and maintain their best performance on their own.

outside ears, and eyes, are important

For decades, research has confirmed that the big factor in determining how much students learn is not class size or the extent of standardized testing but the quality of their teachers.

California researchers in the early nineteen-eighties conducted a five-year study of teacher-skill development in eighty schools, and noticed something interesting. Workshops led teachers to use new skills in the classroom only ten per cent of the time. Even when a practice session with demonstrations and personal feedback was added, fewer than twenty per cent made the change. But when coaching was introduced—when a colleague watched them try the new skills in their own classroom and provided suggestions—adoption rates passed ninety per cent. A spate of small randomized trials confirmed the effect. Coached teachers were more effective, and their students did better on tests.

they did not necessarily have any special expertise in a content area, like math or science.

The coaches let the teachers choose the direction for coaching. They usually know better than anyone what their difficulties are.

teaches coaches to observe a few specifics: whether the teacher has an effective plan for instruction; how many students are engaged in the material; whether they interact respectfully; whether they engage in high-level conversations; whether they understand how they are progressing, or failing to progress.

must engage in “deliberate practice”—sustained, mindful efforts to develop the full range of abilities that success requires. You have to work at what you’re not good at.

most people do not know where to start or how to proceed. Expertise, as the formula goes, requires going from unconscious incompetence to conscious incompetence to conscious competence and finally to unconscious competence.

The coach provides the outside eyes and ears, and makes you aware of where you’re falling short.

So coaches use a variety of approaches—showing what other, respected colleagues do, for instance, or reviewing videos of the subject’s performance. The most common, however, is just conversation.

“What worked?”

“How could you help her?”

“What else did you notice?”

Good coaches, he said, speak with credibility, make a personal connection, and focus little on themselves.

“listened more than they talked,” Knight said. “They were one hundred per cent present in the conversation.”

coaching has definitely changed how satisfying teaching is

It’s teaching with a trendier name. Coaching aimed at improving the performance of people who are already professionals is less usual.

modern society increasingly depends on ordinary people taking responsibility for doing extraordinary things

coaching may prove essential to the success of modern society.

We care about results in sports, and if we care half as much about results in schools and in hospitals we may reach the same conclusion.

It’s an attitude that Dr. Khurana first saw in M.B.A. programs but has migrated, he says, to the undergraduate level.

Second, in management and marketing, no strong consensus has emerged about what students ought to learn or how they ought to learn it.

Gains on the C.L.A. closely parallel the amount of time students reported spending on homework. Another explanation is the heavy prevalence of group assignments in business courses: the more time students spent studying in groups, the weaker their gains in the kinds of skills the C.L.A. measures.

The pedagogical theory is that managers need to function in groups, so a management education without such experiences would be like medical training without a residency. While some group projects are genuinely challenging, the consensus among students and professors is that they are one of the elements of business that make it easy to skate through college.

“We’ve got students who don’t read, and grow up not reading,” he says. “There are too many other things competing for their time. The frequency and quantity of drinking keeps getting higher. We have issues with depression. Getting students alert and motivated — even getting them to class, to be honest with you — it’s a challenge.”

“A lot of classes I’ve been exposed to, you just go to class and they do the PowerPoint from the book,” he says. “It just seems kind of pointless to go when (a) you’re probably not going to be paying much attention anyway and (b) it would probably be worth more of your time just to sit with your book and read it.”

“It seems like now, every take-home test you get, you can just go and Google. If the question is from a test bank, you can just type the text in, and somebody out there will have it and you can just use that.”

This is not senioritis, he says: this is the way all four years have been. In a typical day, “I just play sports, maybe go to the gym. Eat. Probably drink a little bit. Just kind of goof around all day.” He says his grade-point average is 3.3.

concrete business skills tend to expire in five years or so as technology and organizations change.

History and philosophy, on the other hand, provide the kind of contextual knowledge and reasoning skills that are indispensable for business students.

when they hand in papers, they’re marked up twice: once for content by a professor with specialized expertise, and once for writing quality by a business-communication professor.

a national survey of 259 business professors who had been teaching for at least 10 years. On average, respondents said they had reduced the math and analytic-thinking requirements in their courses. In exchange, they had increased the number of requirements related to computer skills and group presentations.

what about employers? What do they want? According to national surveys, they want to hire 22-year-olds who can write coherently, think creatively and analyze quantitative data, and they’re perfectly happy to hire English or biology majors. Most Ivy League universities and elite liberal arts colleges, in fact, don’t even offer undergraduate business majors.
