The educational environment, in its entirety (ethos, environment, educational offer, teacher-pupil relations, pedagogical actions) is oriented towards meeting formally established quality standards in line with the educational needs of the direct and indirect educational beneficiaries. Ensuring the quality of teaching is a concern of teachers, and they are therefore interested in increasing the degree of professional efficiency and, implicitly, their perception and self-perception. This paper, based on qualitative educational research, presents a comparative analysis of ten case studies, based on specific teaching actions undertaken and self-monitored by primary school teachers in Romania, through the practice of self-analysis of teaching activity. In this paper we aimed to explore the triggers of teachers' higher-quality professional performance generated by the practice of self-analysis of teaching activity. As relevant aspects of teaching effectiveness, perceived by the participants in a focus group, following the practice of self-analysis of the teaching activity, we mention the following formative valences of it: use of critical thinking, knowledge of personal and professional identity, identification of answers to self-reflective questions, teaching self-regulation and awareness of dysfunctions in the educational process.
