The aim of this study was four-fold: (1) to explore changes introduced in classroom methodology by secondary school teachers during their participation in a professional development programme, using the digital tool EVALOE-DSS, based on conversational methodology; (2) to analyse the impact of introducing conversational methodology in the development of students’ oral competence; (3) to determine the relation between students’ self-perception of oral competence and self-perceived emotional competence; and (4) to find out the teachers’ opinion about their experience in the programme. The instruments used were the digital tool EVALOE-DSS, the Test of Self-Perceived Oral Competence, the Self-Report of Emotional Intelligence, the Trait Meta-Mood Scale, and a satisfaction questionnaire. The study was developed in four phases: initial intensive training, intervention using the digital tool for four months, students’ assessments and teachers’ evaluations. The results of teachers’ self-assessments using the EVALOE-DSS showed that their self-assessment of classes significantly improved throughout their participation in the programme. In addition, students whose teachers participated in the programme were self-perceived as more competent at oral language, and this had a positive influence on their self-perception of emotional competence. Finally, teachers were positive about their participation in the training process using the EVALOE-DSS. In conclusion, this study seems to suggest that a professional development programme using a Computer Assisted Language Learning (CALL) tool could provide an important strategy for increasing teachers’ oral language teaching quality and improving student learning.engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/journal article0958-8221https://doi.org/10.1080/09588221.2023.2197963https://www.tandfonline.com/doi/full/10.1080/09588221.2023.2197963open accessOral language competenceDigital toolEmotional competenceProfessional developmentSecondary schoolPsicología de la educación (Psicología)6104.02 Métodos Educativos
