Is it immoral to show new students how to use Wolfram Alpha? Currently, I'm working as an assistant at the mathematics department of my university. My job consists of sitting for 20 hours a week in an office to which students come with doubts regarding all the basic math courses.

Today, for example, I was solving a limit in a class full of engineering freshmen. After I solved it, I checked the answer in Wolfram in front of the students and I recommended the website, as well as other useful sites such as Desmos, or Khan Academy.

My afterthoughts were: "what if they start using it when they're not supposed to? (i.e. exams and such)". Does the act of recommending such a site carry any moral consequence?
I always like to show the students Wolfram Alpha in freshman math courses. (Many will already know about it, whether you show them or not.)

There are several reasons for this. The first is that it's a useful tool, both for checking solutions to homeworks, and also for later in life.

But the more important reason is that many students are skeptical of why they have to take a course in calculus. I double down on their skepticism by demonstrating to them that a computer can solve most computational questions on a calculus exam in about 0.05 seconds, and can even "show its work". Having gotten their attention, I now have a good opportunity to make my case for the value of a math education.

As far as exams go, I recommend prohibiting the use of all electronic devices. Some students will cheat on their homework, but that will be true no matter what and in the end they are cheating themselves.
