What a wonderful story. Thanks for sharing!

Caculus is the foundation of everything, isn't it? Earth, star, rocket, motion, statistics, etc, etc...

Thanks, Hong, and yes, calculus offers the mathematical foundation to describe and often explain many otherwise mysterious natural phenomena. I try to encourage all high school students I encounter to get their mathematics sequence done as soon as possible. That sequence represents a "long pole" upon which all the higher level courses depend. For example, engineers rely on differential equations to explain vibrations. Differential equations rely on calculus. Calculus relies on precalculus. Precalculus relies on algebra and geometry. You get the idea.

One can make the same observations about the hierarchy of other disciplines.

Anyone with college ambitions needs to understand this and take productive action on the understanding.

Just for giggles, I share here the "innovative" (read "hodgepodge") schedule of NCSSM during my years there. The basic idea (I think) was to prevent unduly creating a "rut" for students and teachers. I have no idea what studies, if any, corroborate or refute the merits of this approach. But the school still employs it.

Luke,

You do offer good advice in maximizing student value/dollar, but for some students I think that's sort of missing the point. The reason to go to college/university in the first place is to provide an intellectual foundation for the rest of your life. At my college, even people with 5's on the Calculus AB and Calculus BC exams didn't necessarily get entrance into multivariable calculus first semester if they didn't pass the college's own placement exams administered on entrance and there were people with no formal AB or BC coursework or exams who did place out if they did well enough on the placement exam. Also, would you really want to tackle Stokes' and Green's theorem and Jacobian matrices in all their glory without the requisite foundation?

Jim

I just saw the NCSSM schedule. It looks like they devoted a lot of time to science labs which I would consider to be a very good thing if done right.

The story of the elder Mr. Brown is really cool. It must have been interesting to have a math teacher from Exeter. 3 hour long classes is a challenge for BC Calculus. I remember my own visiting professor for Calculus who wore the same University of Michigan sweatshirt to lecture every day :-).

After all that education and struggle, I managed to place into Calculus II as noted in the blog entry. I earned a B in that course and a B in Calculus III the next term. The following year, I earned only a C in Differential Equations.

I talked to a high school AP Calculus instructor recently about AP versus dual enrollment (DE). The latter involves students taking actual college courses for college credit. These are usually taken online or at a local community college. To me, this makes much more sense than merely "hoping" for a good score on a placement test after a year of intellectual flogging.

The AP teacher swore up and down that her AP students could "run circles around" the DE students. My response to that is, "So what?" I do not recall ever signing the dotted line for any agreement to "run circles around" anyone.

Calculus AB spreads one semester of calculus across two semesters. Calculus BC squeezes three semesters of calculus into two semesters. Again, this is senseless. Why not just take one semester of calculus in one semester?

(I want to clarify that last paragraph. The Massachusetts Institute of Technology (MIT) teaches single variable calculus in one semester and multivariable calculus in one semester. Most other colleges spread those two courses over three semesters. So Calculus AB focuses on single variable calculus while Calculus BC also includes multivariable calculus. I do not want to quibble over course content but simply observe that the student can find less onerous ways to earn calculus college credit in high school.)

Moreover, there is this whole issue of writing pages of proofs in calculus. Unless one plans to become a mathematics major, this is a complete waste of time. I recall the story of the engineering professor who told his students: "Do you remember those pages of proofs you had to do in calculus? We use calculus in this course but you will not be doing that here." Ha!

In my ideal world, the student completes the foundation courses for his career at the local community college using online tools from the comfort of his recliner in his parents' home -- no commuting, no fighting traffic, no costly and cramped dormitories, no overpriced and nutritionally dubious meal plans, and no "public master debating" sessions with boorish classmates and overbearing professors. The MathXL tool offers so many advantages over live instruction that I hardly know where to begin. I can say the same for its companion tools in the other disciplines.

But I am an extreme introvert so many people will turn from my attitude in disgust.

Still, having gone through all this, I maintain this firm conclusion:

The excellent is the enemy of the adequate.

Having watched some of my NCSSM classmates drop out of college due to a "burnout" that started at NCSSM, and witnessed other dubious outcomes over the years, I think the facts support my "slacker" attitude.

On the plus side, I could well have done worse in college without the solid foundation NCSSM provided. One of my classmates from my old high school got an A in the standard non-AP, non-honors calculus course there. She earned a D+ in calculus as a college freshman. Ouch!

Today, though, I would definitely select DE over all other options.

Jim, did you do any paid internships while in engineering school?

I ask because the issue of cash flow has not been discussed yet.

One excellent incentive (beyond saving time and tuition money) for earning college credit in high school involves the acceleration toward employment both before and after graduation. I have said many times on this forum that cooperative education (co-op) was the best thing ever to happen to me. Getting those foundation classes out of the way in high school opens the door to starting a co-op job after just a semester at the university. Moreover, motivated students can use the free time outside the day job to prepare for upcoming courses using standardized reference manuals for the Fundamentals of Engineering (PE) and Professional Engineering (PE) examinations. Finally, frugal students can use the income earned from these experiences to finance (at least partially) their educations.

I have an easy workaround for that. It requires a summer free prior to the college freshman year, however. Register at MathXL for $44 and work the relevant Calculus III problems (basically the last five chapters) in Hillsborough CC: Thomas' Calculus, 11e with Precalculus to get familiar with those concepts. This tool offers the complete textbook online along with lecture videos, animations, and interactive examples to help users solve the online problems. In addition, Massachusetts Institute of Technology (MIT) OpenCourseWare (OCW) offers free video recordings of actual campus lectures on multivariable calculus to supplement the MathXL material.

Not sure which of these books at Amazon represent "Hillsborough CC: Thomas' Calculus, 11e with Precalculus"

Steve, purchasing the book is not necessary since the tool includes the electronic version of the book online. The book in question is a variant of Thomas' Calculus Media Upgrade plus MyMathLab Student Access Kit (11th Edition) with the first chapter enhanced to include the equivalent of a full course in precalculus. As the title suggests, the Hillsborough Community College faculty had it built especially for them though anyone can use it.

The reviews for the hard copy textbook do MathXL (or its MyMathLab equivalent) no justice. I rarely refer to the textbook when using MathXL, preferring instead to watch the videos and follow the interactive examples. It really is a life saver for students struggling with mathematics.

Luke,

Good suggestion. A bunch of us used H.M. Schey's  div, grad, curl and all that as almost a supplementary text to the vector calculus portion of multivariable calculus. Also,  college students in technical disciplines should learn quickly about Schaum's Outline Series and work  problems that help you get things conceptually.

You asked if I had done any paid interships. No, despite being from a family of relatively modest financial means my father set up a trust in his will that when executed when he died at 34 and invested allowed for me to attend a private college and 1 year of graduate school no strings attached. Knowing about his foresight and caring in this regard gave me huge amounts of motivation in my studies to do the very best I could. I doubt that I would have been able to afford private college at today's rates without some sort of scholarship or work/study.

I do agree that Co-op programs are very valuable. One of the most valuable parts of Co-op are the interviewing skills you acquire when applying for the job. Making sure a student goes through the process of interviewing at several companies before it is the high stakes of applying for a full time position, even if he doesn't land the Co-op assignment, will assure that he has begun preparation to be gainfully employed upon graduation.
