The traditional face-to-face language school has been replaced with online schooling by virtue of the COVID-19 outbreak. However, recent studies have significantly covered teachers’ emotional attitudes toward online education. What is not yet clear is their cognitive attitudes toward online language education, particularly during the recent pandemic. To fill the current gap, researchers selected Innovation diffusion theory (IDT) as the main theoretical framework and explored 11 Iranian EFL teachers’ attitudes through semi-unstructured interviews. The findings of the deductive content analysis revealed that teachers had positive attitudes toward compatibility features of online education; however, they had negative attitudes toward complexity stemming from Computer Assisted Language Learning) CALL (illiteracy, power cut, and low internet speed. Furthermore, teachers prioritize traditional language learning over online ones. Among many pedagogical implications, this study suggests that pedagogical experts should run some teacher training programs and workshops for English teachers to escalate their pedagogical and professional needs to teach both receptive and productive skills through online platforms. Additionally, English teachers should escalate their CALL literacy to efficiently manipulate their online classrooms, culminating in integrating more online tools in their language classes and placing a premium on online teaching rather than traditional ones.
