PurposeThe authors propose that a digital instructional delivery format of lesson study (LS) may have the potential to amplify particular aspects of traditional, face-to-face LS.Design/methodology/approachThis is a qualitative case study, using data triangulation, member checking and an inductive approach to open-coding utilizing grounded theory to identify codes and themes.FindingsDigital tools promoted LS and learning, allowing for rigorous collaboration, synchronous observations, data collection and feedback, leading to deeper understanding.Research limitations/implicationsDigital tools used in the online LS process changed how instructional planning can be researched, analyzed and written collaboratively and impacted the fluidity of a lesson, the ease of observation and reflection, student engagement and the researchers' and students' ability to share ideas in real time.Practical implicationsLS can be integrated into online teacher education programs to engage students in online learning and promotes engagement, peer interaction and student voice. The use of these digital tools is not restricted just to remote instructional contexts.Social implicationsLS reduces teacher isolation, builds a collaborative community of teachers and increases instructional motivation. Educators across schools, universities or districts can integrate online LS into remote teacher education programs and online courses.Originality/valueThis study is original work that has not been published elsewhere.
