Book Review: a Calculus book for Mathephobes

Today’s book review comes from my office manager at NVTS, Deb Haynes, who is comfortable with bookkeeping but horrified by Calculus!

The Calculus Diaries: How Math Can Help You Lose Weight, Win in Vegas, and Survive a Zombie Apocalypse

By Jennifer Ouellette

Many a parent has heard the lament “I’ll never need <algebra/calculus/fill in the blank> in real life!” Before you take the bait, why not hand your mathephobe this entertaining book instead?

Author Jennifer Ouellette is a science writer and self-confessed mathephobe. Her profession brought her to this realization: “I think scientists have a valid point when they bemoan the fact that it’s socially acceptable in our culture to be utterly ignorant of math, whereas it is a shameful thing to be illiterate. We could all be just a little bit mathier.” (p. 9).

The Calculus Diaries recount her year of exploring calculus in real life. As it turns out, calculus is lurking under activities such as watching the mileage in our spiffy hybrids, contemplating calories consumed versus calories burned, and wondering why the house always wins in Vegas. Not to mention observing the financial markets and learning to surf!

As Ouellette tackles each subject, for instance the application of vector calculus in Disney Land’s Space Mountain roller coaster, she painlessly explains the math concepts in a narrative that includes the colorful history of pertinent mathematicians and scientists. The result is that – even for an English major like me – this never reads like a math book.

Given the very real presence of cholera in Haiti and the omnipresence of zombieism in entertainment, the chapter devoted to disease is riveting. See Appendix 2 “Calculus of the Living Dead” for how to use differential equations to determine at what point your band of survivors is hopelessly outnumbered by zombies.

Great Books or Great Jobs?

This article appears in today’s online edition of The Chronicle of Higher Education. It is an interesting look at the role of the community college in our system of higher education. Is that role, as President Obama has suggested, to train and prepare people for the workforce in an increasingly globalized economy? Or, should the role of the community college be to educate individuals in the liberal arts? This question has been bantered about for at least a quarter century and maybe since the community college system emerged in the post-World War II period.

I have taught at Northern Virginia Community College for 28 years and have seen the value in both approaches. My view is there is a place for both because of the varied needs and goals of community college students – some four-year college bound, some seeking terminal degrees and training for the job market. I certainly cover much theory and “academic” topics in my sociology classes, but I also spend plenty of time providing practical training for students who seek to enter the job force – writing skills, public speaking skills, critical thinking skills, problem-solving skills – through group presentations and individual oral presentations. There is no reason why an academic approach and a more practical approach need to be mutually exclusive.

Parents…Chill Out!

How Can Students Be More Realistic and Parents Reduce Their Anxiety Level?

I am often asked this question when I give presentations and workshops. This may be the ultimate question for college-bound students and their parents. Parents wrestle with it constantly and kids pick up on parental “vibes,” which only exacerbates the problem. The most important thing to remember is that your child will be successful in spite of himself!

Most of the short-term, seemingly insurmountable obstacles facing your child as he or she progresses through elementary, middle, and high school will, in most instances, fall by the wayside as they grow to adulthood. After all, your child has caring, educated parents who will do whatever it takes to help them succeed, right? The likelihood of failure is slim, particularly in families where both parents are college educated. Research supports this assertion.

In addition, keep several things in mind. First, all of life’s decisions do not need to be made by the age of eighteen. Second, failing occasionally is not a bad thing. In fact, if you study some of the most successful individuals in history, failure was the norm for them before they achieved success. I have heard students in my sociology classes at the college state that their parents never let them fail and that they were always cautioned to avoid situations where they may not succeed.

When applying to colleges, students are told to prepare applications that make them seem perfect. This is not necessarily what an admissions officer is seeking. In fact, many admissions officers have written and spoken about the fact that they seek students who have experienced adversity, only to overcome it and go on to succeed. The ability to rebound from adversity is something we all admire – including college admissions officers. No one is perfect at any age, and certainly not at the age of eighteen.

Third, if the college of first choice does not accept your child, is that such a bad or catastrophic thing? You know that next year they will be studying in some college somewhere. There is a college for every student in America, and if your child applies himself to his studies, that college will be a good choice to launch him on to his career. The “first choice” college will seem an irrelevant distant memory in five years. And, let’s face it, when your daughter calls home a month after arriving on campus and tells you she loves college, finds her classes motivating and inspiring, and enjoys living with her roommate and, oh, by the way, has to run because she is supposed to meet a study group in ten minutes, is that not exactly what you wanted to hear?

So, relax, be the best, most supportive parent you can be, but do it in a non-intrusive manner that is “acceptable” to your teenager. In most instances, any advice you offer will be rejected outright, even if you do have a doctorate in counseling psychology – because you are their parent! At some point in their adult life, they will realize you actually do have a brain and they will then ask for your advice. Until then, advise discreetly from the sidelines. That is the first step toward reducing your anxiety level – and theirs.❖

The disconnect between employment and education sectors of the economy

This article points to an obvious disconnect between employment and education. I had two immediate reactions to the article. First, the role of the community college in addressing this matter is critical. It is the gateway for millions of Americans to enter (or re-enter) the middle class. President Obama seems to recognize this reality through his endorsement of community colleges as a major player in addressing the current and future employment picture in America.

The second thing that came to mind as I read the article is the value we place on education and our unwillingness to compensate teachers to reflect their market value. Is it any wonder that a young adult would choose a career in, for example, technical writing in the private sector at a starting salary of $65,000+ rather than a K-12 teaching position starting salary of $45,000 or less? America simply has not connected the dots between the value of an educated workforce, our future economic stability and global competitiveness, and fairly compensated, highly trained K-12 educators. We have never come to grips with the fact that we simply do not value the work of teachers nor do we compensate them in accordance with their value to society, but expect them to perform miracles for our children. In fact, rather than compensate (and respect) teachers in a manner commensurate with their value to society, America seems to have declared open warfare on teachers and public education, not to mention public employee teacher unions.

So, when Jeffrey Bergstrand states “But education is the key to the U.S. being able to take advantage of this opportunity One of the biggest issues that I hear from managers and executives is that they need to hire workers, but can’t find those who have the educational skills to be productive. This condition alone will lead to a permanently higher unemployment rate”, we should all take note of this critical factor in solving our long-term employment dilemma.

Gender Inequality or Motherhood?

This is a fascinating article. The thought that came to mind immediately was the sociology inherent in this issue, not the physical science. It seems that systemic gender bias and inequality in STEM areas of academia has been reduced but certainly not eliminated. Women have made strides in these fields, but are not yet on par with men in the percentage represented in the workforce.

However, the sociological reasons for the lack of women in STEM areas is far more intriguing. Motherhood (nature) seems to be an intervening variable that few anticipated thirty years ago when the push to get women into the fields of math, science, and engineering commenced. So, what do you think? Does this confirm what the sociobiologists have been saying for generations – that there is a biological difference between men and women and the roles they play (nature). Or, is it nurture – women and men are simply gender socialized to be what a culture determines is the appropriate roles for them to play and biology has nothing to do with it? And if so what, if anything, should government and industry do to address the issue?

Too much tech in teaching?

This is an interesting article on the use of technology in the classroom. I see it at the college often – young professors who use technology to try to either “fit in” and be cool with their students, or, worse yet, use technology as a crutch for limited instructional and interpersonal skills. I use technology in multiple forms in my classes (BlackBoard, Discussion Board, Youtube, on line instructional videos, PowerPoint, etc.) and believe there is a real benefit to it, if used judiciously. However, the author’s comment about “the bond between professor and student” is the crucial variable in the teaching process. Students need to see you as human first – a compassionate communicator – then the use of tech tools can supplement that greater quality. Some things just never will change. People, including students, need and want human connectedness.

Is a College Degree Worth the Expense and Effort?

Michelle Singletary has written an interesting article in today’s Washington Post on the issue of matching college majors with the job market (see attached). Ms. Singletary makes some very good points. She very accurately points out that there needs to be a balance between the desire to seek an education and to become marketable and prepared for the job market in a very difficult economic environment. I, too, have written about this issue as recently as last year when I published “Matching College Degrees With the Job Market” (see our web site, www.nvtutoring.com and click “Articles” to access this essay). All parents and students need to keep practicality in mind as they pursue a college degree. In a globalized economy where competition in all fields has become a critical issue, not at least considering the marketability of a degree may be a decision that will have significant consequences in the future.

Is it nature, or is it nurture?

This article that appears in today’s online issue of The Chronicle of Higher Education sheds some new light on an age-old controversy – is nature or nurture more at play when examining the disparity between men and women in the area of math aptitude and achievement.

My anecdotal observation (certainly not scientific, by any means) is that women have made enormous strides in the fields of math and science during the past several decades. When I began my business 17 years ago, it was virtually impossible to find a female who could tutor higher level math or science. Now, easily half, if not more, of the math and science tutors I have hired during the past 5 years are female. This study questions the validity of gender bias in math and science and at least implies that there may be more to the alleged inequity than can be explained by gender stereotyping. You be the judge. I welcome your comments.

The Cost-Effectiveness of E-Textbooks

The cost of textbooks is particularly acute at the community college where I teach. Students attending community colleges are often struggling financially and are working one or two jobs, juggling family responsibilities, and commuting by bus to school. It is a tough slog for many of my students just to get enough money to pay tuition, let alone $150 for a textbook – and for that price, the books are paperback! Will e-texbooks be the solution? Like most innovations in the digital world, the answer is unclear. Issues as complex as pricing and as simple as user-friendliness complicate the issue. It is not as simple as downloading a book and going off on one’s merry way. Many of my students also tell me that they like a physical copy of the textbook that enables them to write in it, highlight it, and otherwise engage in the textbook. The technology apparently is not there yet to permit that in the e-textbook world.

This article addresses some of the issues associated with this issue:

Early Decision

I have published an article on the topic of early decision and have attached it here. I welcome your comments and responses!

Early Decision: Whose Interests Are Being Served?

By Dr. Ralph G. Perrino

 What is Early Decision?

Early admission programs are not all the same. Variations such as early decision and early action confuse students and parents alike. Students seeking early decision generally apply in November and receive an answer within a month. Under this scenario, applicants submit only one application to one school. Acceptance by the college is binding. Binding typically means applicants promise they will attend the school if their application is accepted. Schools expect admitted students to honor their pledge. Colleges share their early decision lists of admitted students and follow the practice of eliminating them from further consideration. If a student does not honor an early decision, it is unlikely competitive schools will accept the student. This differs from early action where a student is accepted by mid-December but is not bound to acceptance to the school. Unlike early decision, there is no penalty for not attending the college that has admitted the student. This article focuses mainly on binding early decision programs.

 Early Decision: Student Readiness and Family Income as Determinants

Some students and parents think early decision applicants have a better chance of getting into some of the most selective colleges. This notion is controversial and not everyone agrees. Part of the perception about early decision evolves from the small number of schools that use early decision. Approximately 400, or three percent, of colleges offering four-year degrees have early decision programs. These schools are concentrated in the Ivy League and very selective and expensive private colleges. Since early decision often applies to a group of schools that tend to be ranked among the “best” schools by U.S. News & World Report, the connection between early decision and elite schools may be enough for many people to see it as an advantage.

A November 5, 2011 article in the The Huffington Post offers some of the advantages and disadvantages to students of early decision. Among the advantages are: they just want to get the college application process completed so they can enjoy the second semester of their senior year; early decision may afford priority housing preference for incoming freshmen; and early decision demonstrates commitment to a school and may facilitate acceptance of a student who may be a borderline candidate.

Some of the disadvantages of early decision to a student are:  they think they know their major, but realize later in the year that their goals may have changed; a student may simply change his or her mind about where they would like to attend college (for example an urban school may have seemed like the right thing to do until a student visits a small, liberal arts college in a rural setting); and the possibility of financial aid may be impacted because a college that knows you are committed to their institution may not give a student as much money compared to a situation where the school is trying to attract the student.

Christopher Avery and several others have studied and documented some of the early decision process in their book The Early Admissions Game, Joining the Elite. (Cambridge, Mass: Harvard University Press, 2003) Colleges that use early decision usually argue it is not an advantage for admission. However, Avery’s research indicates that applying early decision does, in fact, increase an applicant’s chances by as much as a 100 point increase in their combined SAT score. For some students, that doubles or even triples the chance of admission. Even vocal proponents of the fairness of early decision, like Princeton, admit two to three times as many applicants under early as opposed to regular admissions.

Students and parents would do well to remember that early admission implies decision-making for both the student and the institution. Completing the process early is more appropriate for some students than others. Early admission can be revoked if a student’s GPA drops precipitously, so an early decision is not a free pass to coast through the rest of senior year.

A major disadvantage for some students, states the Chronicle for Higher Education, is that, “A common criticism of early decision programs is that they hurt students from low-income families, who often decide to forgo early applications so they can compare financial-aid offers from multiple institutions during the regular admissions process.” The fact is that early decision programs limit choices for any family in need of financial aid. This inevitably widens the gap between the privileged and the underprivileged, or at least the privileged and the middle class, and impacts campus diversity.

In a study that appeared in the American Economic Review (December 2010), Christopher Avery and Jonathan Levin stated that early decision by elite colleges “tends to be captured by students who are well off and well informed” and that “some prominent academic leaders have argued that early admissions should be curtailed.” Recognizing the inherent inequalities associated with early decision, Yale and Stanford Universities changed from early decision to early action in 2003-2004. During the fall of 2006, Harvard University announced plans to end its early decision policy entirely. In 2007-2008, Princeton University followed Harvard’s lead. Harvard’s Dean of Admissions and Financial Aid, William R. Fitzsimmons, stated “Early applications tended to be disproportionately white and affluent, and there was a growing perception that early admissions was becoming an exclusive club, to which somehow only a few were invited. That worked against the whole idea of access.” Given the visibility and reputation of Yale, Stanford, Harvard, and Princeton, these developments have encouraged other colleges to reevaluate their own early decision programs.

 The Dilemma College Admissions Officers Face

That was 2003-2008. Fast forward to 2009, in the midst of one of the most serious economic downturns in American history. The picture has changed significantly. The October 21, 2011 edition of the online higher education publication Inside Higher Ed reports that, “The recession appears to have been very good for the practice of ‘early decision’ in which applicants must commit to enroll if admitted. Not only are many colleges reporting increased interest from applicants in applying early, but 2009 saw a jump in the proportion of colleges reporting that they were increasing the number of students admitted this (early decision) way.” The economic pressure is clearly on colleges to admit a larger percentage of early decision applicants than regular applicants (70% vs.55%). Inside Higher Ed has also reported that “47% of colleges reported an increase in the number of early decision applications they received, about the same proportion as the previous two years.” Further, according to Inside Higher Ed, 65 percent of colleges that actively apply early decision policies reported that they admitted more students in 2009 than in 2008 through the early decision process.

So, although many admissions officers readily agree that early decision favors wealthier students, the economic tug associated with filling classes early in the year is too tempting to resist during economic hard times. Time is money, in the opinion of college admissions officers who are increasingly under pressure to eliminate the uncertainty of freshman class size as the academic year approaches. According to Insider Higher Ed, “”Many admissions officers say they agree with the critics (of early decision), yet can’t resist a tactic that allows them to fill a larger share of their classes earlier in the year.”

 Why Colleges Like Early Decision

Colleges like early decision programs because it is a good way to compete for the most talented students. Early decision eliminates some of the guesswork for college admissions directors. Colleges lose half or more of their admitted students to other schools so early decisions help smooth out the budget process. After all, in the end, operating a college efficiently and effectively is all about business management.  In the eyes of many college admissions officers, an early decision student is a low risk investment.

In an interview with writer James Fallows and Bruce Poch, Admissions Director at Pomona College, Mr. Poch reported that early decision for them becomes a measure of commitment. “It’s worth something to the institution to enroll kids who view the college as their first choice,” he says. “Fewer people are whining about transferring from day one. They turn out to be a lot of the campus leaders.”

College admissions officers are less likely to talk about the U.S. News & World Report rankings but there is suggestion that early decision can improve a school’s statistics. The US News rankings procedures have changed over the years of publishing their national rankings lists of the nation’s best colleges. The statistical measures that matter here are a college’s selectivity and its yield.

Selectivity measures how difficult it is to get into a school. A school that accepts one applicant out of four is more selective than one that accepts two out of three. A college’s yield is the proportion of students offered admission who actually attend. In practice yield measures “takeaways”; if one school gets a student that is admitted to several other universities, it scores a takeaway from each of the other schools. The higher the yield and the larger the number of takeaways, the more desirable the school is thought to be. Under this process, early decision provides a way to improve a college’s selectivity and yield simultaneously, thereby elevating the school’s national ranking. This, in turn, attracts more of those low risk students a college can count on to graduate from their school.

So, while it is admirable that administrators like Harvard’s William Fitzsimmons see the inherent inequality of the early decision process, economic forces often force elite schools to balance principle with practicality.

 A Final Thought

Despite Harvard’s decision in 2006 to drop their program, and Princeton, Yale, and Stanford’s decisions to follow suit, early decision is probably not going to disappear anytime soon, particularly during a period of serious economic decline. Possible reforms would assure more consistent aid packages and limit the number of students accepted. While early admission can help the bottom line of colleges and universities, it holds the inherent risk of creating a two-tiered higher education system that excludes those of lower socioeconomic status. This cannot serve the greater interests of a fair and equitable higher education system predicated on merit, not wealth and privilege.
