I am an advanced mathematics instructor at a day and boarding school in England. My interest with Mathematica is for pedagogical improvement within my classroom (primarily calc I & II and linear algebra). My primary belief is that high level authentic mathematics learning happens without technology; moreover, technology, if not used judiciously, does more to subvert nuanced mathematical thinking in the classroom than to promote it.

comment Using an InputField to define a function to compose with a sequence
Leonid, Thanks for your help. I will study your solution. Also, I found your book and have begun reading through it. Thanks for leaving it open to all. I scheduled to attend a Mathematica intro at the end of the month. I've caught the bug.

comment Using an InputField to define a function to compose with a sequence
My students all have access to Mathematica so it is not essential that Manipulate be the outermost, but ultimately I want the choice to incorporate it into a cdf if the program seems to have real pedagogical value.

comment Using an InputField to define a function to compose with a sequence
I'm sorry, I was not clear before. I have considered your code and I am not sure how to incorporate it. This is an example of what I hope to achieve. A function input field appears with a default function, say (x^2 - 4)/(x - 2), below an input field to hold a default sequence say (2 + 1/n), and finally an input field that will determine at what natural number the sequence will start. Then I want the sequence of ((2+1/n)^2 -4)/((2+1/n)-2) to be computed and displayed. The goal is that a student can input some function and investigate its behavior for an some limit point with some sequence.

comment Upon opening my notebook, I must evaluate cell for code to work properly
I spoke too soon. Only the initialization code worked. Thanks kalewallace. I was experimenting in the same file, so the savedef code suggestion worked since the initialization code worked which I ran first.

This also worked, Thanks! What is the difference between putting the initialization inside the manipulate vs the savedefinitions->true?
