What Do Teacher Candıdates Know About the Limits of the Sequences?

candidates. Research is a case study in which qualitative methods are adopted. The first phase of the study wasconducted with a total of 45 teacher candidates taking the course of Analysis III. At this stage, the "Limit KnowledgeTest in Sequences", which was developed by the researchers to investigate the concept knowledge of the sequenceconcept, was used as a data collection tool. At this stage, "Limit Knowledge Test in Sequences", which wasdeveloped by researchers to investigate the limit concept knowledge in sequences of the teacher candidates, included2 open-ended problems were used as data collection tool. In the second phase of the research, individual interviewswere made with 8 teacher candidates selected from the sample to conduct in-depth research. Content analysis wasused to analyze the obtained data. As a result of the analysis of the data, significant shortcomings were found in theknowledge of the concept of the limit topic in the sequences of teacher candidates. It is seen that the candidates donot know the importance of the concept of "accumulation point", which is indispensable to convergence.
