Calculus I - without a calculator

Click For Summary

Discussion Overview

The discussion revolves around the use of calculators in Calculus I courses, particularly in the context of exams and learning. Participants share their experiences and opinions on whether calculators should be allowed, the implications for learning calculus concepts, and the nature of problems typically encountered in calculus.

Discussion Character

  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants argue that real mathematics is about applying concepts rather than crunching numbers, suggesting that no-calculator tests can enhance understanding.
  • One participant notes that problems in calculus are often designed to yield simple answers, implying that complexity in answers may indicate an error.
  • Another participant mentions that the prevalence of graphical calculators capable of symbolic integration may contribute to the decision to prohibit calculators in exams.
  • Several participants express strong opinions against the use of calculators, claiming they can hinder learning and understanding of fundamental concepts.
  • One participant shares a personal anecdote about using a calculator for specific calculations, contrasting it with historical figures like Euler who performed extensive calculations by hand.

Areas of Agreement / Disagreement

Participants generally agree that calculators are not beneficial for learning calculus, but there is no consensus on the extent of their harm or the necessity of their prohibition in exams. Multiple competing views remain regarding the role of calculators in education.

Contextual Notes

Some participants reference personal experiences and anecdotal evidence regarding the impact of calculators on learning outcomes, but these claims are not universally accepted or substantiated within the discussion.

I'm taking Calculus I in the spring and the instructor sent out out an email outlining the course. He stated that he did not allow calculators on the final. Is this common? I did well in my precalc maths, but I like to be able to check my answers with a calculator - especially during a test. I have seen comments that you don't need a calculator for calculus.

Thanks,
Steve

Real math isn't done with a calculator. It's not about crunching numbers; it's about applying concepts.

No-calculator tests are actually to your advantage, for two reasons:

1. The problems should be simple to work out by just applying the concepts. No laborious long division or any such distractions, and

2. The problems will likely be designed such that the answers come out to nice, simple formulas (note that the idea of "simple" varies, of course). Therefore, you know that you're doing something wrong if your answer starts to get too complicated.
 
This is extremely common and I believe for the best as Ben Niehoff has noted.
Boo calculators!
 
I suspect the reason is the number of graphical calculators that can do symbolic integration - you rarely need to quote a decimal answer in a calculus class.
 
I like never use a calculator!

I still have my old HP-49G, but I don't remember how it works. :P

My calculator is made entirely of deceased trees!* If I need to crunch numbers I fire up Excel or Maple.

* In various states of processing and decay.
 
i never allow them. they are quite harmful to learning actually. most of my current calc 2 students were totally unable to find a simple plane area on my final due to not being able to even graph the region. i suspect they had been allowed to use graphing calculators on exams in high school.

nothing wrong with a calculator after you understand the material but when learning it, it is a large hindrance.
 
Calculators don't have their place in Calculus or Analysis.
 
well i used mine to calculate e to 9 or 10 places, from about 14 terms of the taylor series. i have a $10 "scientific" calculator, with all the bells and whistles i ever use.

then i noticed that euler listed about 100 places of pi done presumably by hand, (but he was off in about the 80th digit, unless his book has a typo).
