The visibility of the teaching and learning process implies the active involvement of teacher and student. The teacher must approach teaching through the filter of how the student learns. The student, in his turn, has to become his own teacher. The relationship of interdependence between the approach of teaching and that of learning is managed by the teacher, who helps the student to learn by the used training and evaluation strategies. This study aimed to find out teachers' opinion about the visible teaching and learning, through a survey based on a questionnaire. The respondents are teachers, who have voluntarily accepted to participate in the survey. The research instrument is a questionnaire designed by researchers and applied online. The obtained results highlight the importance given by the respondents to the careful planning of the didactic activities so that the intentions, the decisions, the strategies and the evaluation practices could be justified to the students in order to be understood and accomplished/implemented by them. However, most of the respondents express their agreement about the necessity of using evidence and argumentation as a basis for the teacher's actions and decisions and about the importance of providing and collecting feedback and formative assessment practices for the efficiency of teaching-learning process. The present research suggests, based on favorable appreciation given by respondents to visible learning, the necessity of curricular revisions.
