New, deeper AP program
[This is my Local Living column for Jan. 28, 2010.]
If someone told you the College Board was about to rip apart the SAT and rebuild it, would that excite/surprise/aggravate/frighten you? Me too. It’s about to happen, not to the SAT, but to our nation’s second-most influential test, Advanced Placement, with large consequences for our high schools and colleges.
The AP program has such a tight grip on the school curriculums of suburban areas such as ours that it has come close to inspiring the same fear and consternation as the SAT and ACT. [See my new rankings of all Washington area schools, based on AP and International Baccalaureate test participation, this Monday on this blog and in the Post.]
I think that’s good. AP is better than the SAT or ACT. It is a challenging series of courses in three dozen subjects ending in three-hour exams, independently written and graded with many essay questions, that can earn college credit and encourage thought and analysis. Many experts say AP could be even better, and they are about to have their way.
The revised AP courses, beginning with biology, will put more emphasis on conceptual understanding and cut back on memorizing content, the designers say. AP will become more like the International Baccalaureate program, which is also popular in this area. Teachers may go deep into some topics and rush quickly past others. Essay questions will focus on concepts, so students will be able to use facts from the topics their teachers choose without having to master every detail in every subject category. Multiple-choice questions will test analytical skill, not memory.
Change means adjustment, and change in the angst-ridden college admissions process, of which AP is a vital part, can bring feverish resistance. Remember, they are tinkering with AP Biology, what some students and parents see as the first big step toward a top medical school.
Here is my question: What are the state universities going to do when they see AP abandon the fact-based, content-heavy approach of the standard college introductory courses that AP was designed to mimic? After biology and the other sciences, French language and culture, German language and culture and world history will change, and I expect other AP courses and tests will go the same route.
Spencer A. Benson, associate professor of cell biology and molecular genetics at the University of Maryland and co-chairman of the College Board panel leading the AP Biology changes, said he expects the shift will be welcomed by colleges that have switched to the conceptual approach. He hopes others will follow. Maybe, say I. But there are big state schools with huge Biology I classes where the final is a few hundred old-style multiple-choice questions. I am not sure they are going to change just because some high school program says they should.
Ready for some mental exercise? Here is an AP multiple-choice question of the old type I borrowed from Science magazine: Which of the following physiological effects would likely occur first in a volunteer who was breathing air from which CO2 was removed?
(a) Decreased blood pH,
(b) Decreased respiratory rate,
(c) Increased respiratory rate,
(d) Increased pulse rate,
(e) Increased blood pressure.
Here is the new type of question:
H+ + HCO3- [arrow pointing both left and right] H2O + CO2.
The equation shows a reversible reaction that occurs in blood. An Olympic marathoner training at a high altitude in Colorado feels dizzy and begins hyperventilating while taking a run. Her blood pH is elevated, resulting in alkalosis. How will normal blood pH be restored?
(a) An increase in O2 concentration in the plasma will lead to a decrease in H+ concentration,
(b) An increase in CO2 concentration in plasma will lead to an increase in H+ concentration,
(c) A decrease in sweating will lead to an increase in HCO3- concentration,
(d) A decrease in respiration will lead to an increase in plasma O2 concentration.
Hmm. I am told that both answers are B. The new style requires the student to understand the formula, not memorize a specific case. But that’s hard. Hard stuff is often unpopular. Will the new AP survive?
