The COVID-19 pandemic is a huge challenge to the world. It has interrupted many aspects of lives, especially education settings. Emergency remote education was put into practice to ensure the continuity of education while learners are physically out of universities, schools and institutes. The purpose of the present study was to investigate the effect of learners’ attitude using Adobe Connect on their final course scores in synchronous online teaching. 75 participants from Qazvin University of Medical Sciences and Health Services participated in this study. Data were gathered by means of a questionnaire and final course exam. A one-way ANOVA was used in order to analyze the data. Results revealed that the attitude level significantly affected the participants’ final scores (F = 18.503, p < .01). The participants who had higher attitude levels had higher final scores.
