Abstract: The digital personality cherishes interdisciplinary characteristics, which form an empirical proposition in university classroom teaching in the era of digitalization. Since digital personality is constructable, it presents a diversified systematic pattern, among which digital consciousness, digital memory, digital identity and digital self-image constitute the core pillars in digital classroom teaching. Given that classroom teaching in universities is a"student-centered, teacher led"process, both teachers and students' digital personalities must interact positively in order to produce the desired results. Improving digital personality requires establishing a digital consciousness, enriching digital autonomy, fully exploring the positive aspects of digital self-image and identity recognition, cultivating students' personalities to shape critical and reflective thinking and promote innovation ability.
