||Differentiation and integration are two major domains in calculus. Their
formulas are important in solving application equations of almost all
disciplines. Students find calculus difficult especially in course of MAT 183,
MAT 235 and MAT 238; it is often because of a failure to recall and apply the
exact formulas of differentiation and integration of transcendental functions.
Furthermore, they could not differentiate and integrate correctly caused to
be confused about many formulas and often interchanged the differentiation
and integration formulas. With these, QR Differentiation and Integration (QR-
Di & In) was introduced to minimize students’ difficulty in memorizing
formulas; to hone students’ study skills in calculus and to increase the
positive attitude of students towards calculus with fun way.
Two different sets of cards for each differentiation and integration functions
were used for practice. One set card name as a function card and the other
set call an answer card. The function card consisted of function is on the top
of it and QR code as the answer to the function is on the bottom of it. A total
of 70 basic functions were selected included functions of the polynomial;
exponential; logarithmic; and trigonometric. Students practice differentiation
and integration by using the function card and do self-checking by scanning
the QR code. Moreover, the student can have logic and strategy practice by
matching the function card to the answer card which is displayed according
to the pyramid layout.
Results of the pre and post-test have shown that there was an increment of
mastering the differentiation and integration formulas. QR- Di & In offer new
fun ways to engage students in studying differentiation and integration as
well as provide another way of teaching to educators.
