What year do your students start using graphing calculators? In my high school, a few students in Y11 and some students in Y12 use graphing calculators. Also our Y11 Algebra test is a non calculator test which causes a few upsets, especially to lower able students who relied on it to work out fraction problems and similar. <br />Does your high school use external assessments as well? If so, how dies your "asking conceptual questions approach" relate to assessments not created by you or your department?

I have always assumed no-calculator questions encouraged the students to prove they could solve it without help, but I really like the idea of changing the question to one that they can't answer with technology such as having them create a problem that has a specific answer rather than find the answer. With technology become such an important part of our world and students wanting to use it more and more, I do agree that telling them they are not allowed to could feed a negative view of math. I think it would be good to have questions that the students couldn't use technology to answer, but to design them in such a way that a "no-technology" statement is not needed.

I found your post very interesting, but there are some points I disagree with. My main concern is twofold:<br /><br />1) Technological solutions can show a limited degree of understanding - showing only that the student knows how to use the technology, not apply the mathematical concept. For example, many of the graphing calculators can also do direct solutions, using syntax such as solve(). <br />2) If questions are designed such that a direct technological solution (such as using solve() or simultaneous solution graphing), it is difficult to determine the reason that a student was unsuccessful. Were they unable to use the mathematical technique? Were they unable to interpret the question context?<br /><br />Finally, facility with solving mathematics on pen and paper has a (theoretically) greater potential of developing mathematical fluency.CyberChalkynoreply@blogger.comtag:blogger.com,1999:blog-386409393041651040.post-7382313461286661772016-02-02T19:01:32.183-06:002016-02-02T19:01:32.183-06:00Thanks for your comment Jim.

But an issue than we can continually adapt our assessments to be more technology friendly. But I know that this issue is not going away.

I would be concerned that in a lot of classrooms, the ability to always have a calculator would mean less work for students and less understanding.Jimhttps://www.blogger.com/profile/11393959087289778865noreply@blogger.comtag:blogger.com,1999:blog-386409393041651040.post-57175534163455410372016-01-30T09:01:39.176-06:002016-01-30T09:01:39.176-06:00I completely agree with you as well!

My classes consist of all skill levels, so I can't say to my advanced students you can't use it and to my struggling students you can. Therefore, I let them all use it and like you said, change the way I ask the question. The ONLY class I may have no calculator questions on a test is for Precalculus, in order to prepare them for AP Calculus and college courses. Until this changes, I do feel I have to prepare them for what's to come.Tyra Frederickhttps://www.blogger.com/profile/13797034973341494147noreply@blogger.comtag:blogger.com,1999:blog-386409393041651040.post-68150350391891234912016-01-27T21:27:12.299-06:002016-01-27T21:27:12.299-06:00I understand the fear.

I hope that their use of technology will give them good problem solving skills for when they get to those classes. I want to do my best for my students right now. However, I worry too.

Having said that, I keep coming back to the fact that many colleges and universities are not allowing calculators on tests (this is what I hear from many of my former students). I worry that my kids are not going to be prepared for that. Thoughts?JimPa23https://www.blogger.com/profile/13383534345522824846noreply@blogger.com
