Abstract 
Integration is one of the major domains in calculus and a fundamental
concept in secondary school and university. Its formulas are important in
solving application equations of almost all disciplines. Students have poor
performance in Integral Calculus and researchers have found that one of the
reasons is a failure to recall and apply the exact formulas of integration into
functions. Furthermore, they also could not integrate correctly caused to be
confused about many formulas and often interchanged the differentiation
and integration formulas. Therefore, IIntegration was introduced to minimize
studentsâ€™ difficulty in memorizing formulas; to hone studentsâ€™ study skills in
integration and to increase the positive attitude of students towards
integration with fun ways.
Two type sets cards are used for conducting 2 activities. Cards are named
as function cards and answer cards. Function cards have a function and QR
codes. QR code is the answer correspond to the respective function. Activity
1 was carried out to help students recall; memorize and identify the exact
formulas into different types of functions. Students integrate the function
cards and then, do selfcheck by scanning the QR code. Activity 2 is
considered as logic and strategy practice which assists the student in
practice; apply and distinguish the exact formulas. Students use their
function cards to remove the corresponding answer cards, which are
displayed in the pyramid layout.
Upon several practices, results of pre and posttest have shown that an
increment of using exact integrating formulas into different types of functions.
IIntegration offers new fun ways to engage students in studying integration
as well as provide an alternative way of teaching to educators.
