In this study, an attempt was made to investigate the constraints encountered by student teachers during their practicum experiences at some selected colleges in Oromia, Ethiopia. Adopting a convergent mixed research design, a questionnaire was distributed to student teachers, and a semi-structured interview was conducted with supervisors and mentors. The data found from questionnaire were analyzed using a descriptive statistics, inferential statistics and One-Way ANOVA. Besides, the interview results were analyzed using content analysis method. In the findings, factors such as mentors’ lack of continuous follow up and support, interest to share experience, and friendliness were identified. In addition, follow up and support were not continuously provided by supervisors, and there was no coordination between supervisors and mentors. Further, Colleges engage large numbers of candidates to one school, allot many student teachers for one academic supervisor, opportunity given for practice was inadequate and there was lack of necessary facilities in the cooperating schools. Hence, it can be concluded that there were limitations from the side of mentors, supervisors, colleges and cooperating schools on playing their roles in teaching practice. Therefore, based on the findings of the study and the drawn conclusions; mentors and supervisors of the practicum should make continuous follow up and provide immediate feedback for their student teachers. In addition, they should collaborate while evaluating and equipping their student teachers with all necessary things. Besides, colleges should have good rapport with cooperating schools, try to fulfill necessary facilities, and strengthen to make them effectively produce qualified students. They should work on how to mitigate the number of student teachers with the number of supervisors and schools. Finally, cooperating schools should learn from spontaneous limitations and go further to fulfill their needs.

在这项研究中，试图调查实习教师在埃塞俄比亚奥罗米亚州一些选定的大学实习期间遇到的限制。采用聚合混合研究设计，向实习教师发放调查问卷，并对导师和导师进行半结构化访谈。使用描述性统计、推论统计和单因素方差分析对问卷中找到的数据进行分析。此外，采用内容分析法对访谈结果进行分析。在调查结果中，确定了导师缺乏持续跟进和支持、分享经验的兴趣以及友善等因素。此外，导师没有持续提供跟进和支持，导师和导师之间也没有协调。此外，高校一校招收大量考生，一名导师配备多名实习教师，实习机会不足，合作学校缺乏必要的设施。由此可见，导师、导师、学院及合作学校在教学实践中发挥作用存在局限性。因此，根据研究结果和得出的结论；实习导师和主管应持续跟进并为实习教师提供即时反馈。此外，他们应该在评估学生教师并为其配备所有必要的东西时进行合作。此外，高校还应与合作学校搞好关系，尽力配备必要的设施，加强合作，使其有效培养合格的学生。他们应该研究如何减少实习教师的数量以及导师和学校的数量。最后，合作学校应该吸取自发的局限性，进一步满足他们的需求。
