RT Journal Article T1 A digital tool designed to support secondary education teachers’ professional development and to develop students’ oral language competence A1 Gràcia Garcia, Marta A1 Alvarado Izquierdo, Jesús María A1 Vega Llobera, Fàtima A1 Jarque, Maria Josep A1 Castillo Mardones, Pamela A1 Adam Alcocer, Ana Luisa AB Digital tools can guide and support teachers in professional development programmes. 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.
