Investigating Pre-Service Elementary Mathematics Teachers’ Perception of Integral

The purpose of this research study is to examine the perceptions of the pre-service elementary maths teachers who attended a teaching application enriched with the modelling activities toward integral concept within the context of anxiety, attitude, and daily life usage awareness. while the quantitative data of the research were obtained from the perception scale for the concept of integral that was developed by the researchers and whose validity and reliability studies were conducted, the qualitative data of the research were gathered through the semi-structured interviews. at the end of the study, it has been seen that the teaching application enriched with the modelling activities decreased the anxiety levels of pre-service teachers toward the integral and increased their attitude and awareness levels regarding its usage in daily life.
