Research of an online-offline blending teaching model for the post COVID-19 era—Using a C programming language course as an example

This paper aims to study the new changes in higher education in the post COVID-19 era and proposed an innovative Online-to-Offline (O2O) blending teaching model, named BOPPPS-SPOC by tracking a C programming language course. BOPPPS-SPOC indicates implementing BOPPPS mode for SPOC (Small Private Online Course). BOPPPS is an acronym for 6 components: Bridge in, Objective, Preassessment, Participatory learning, Post-assessment and Summary and it makes the classroom teaching arrangement more logic and rationality. The new changes are: (1) Teaching Methods: From separated online and offline teaching to an online-offline blending teaching. By adopting the new BOPPPS-SPOC method, the traditional offline and online independent teaching, implemented in a serial way, is optimized into offline and online blending teaching, implemented in a cross-parallel way, and it effectively expand the time and space scope of classroom teaching; (2) Course Evaluation: From single-dimensional evaluation to multi-dimensional evaluation. It focuses on the construction of a fusion evaluation system, mainly including the formative evaluation of teaching process and the sum. Finally, a survey from an authoritative research institution is conducted to 334 universities in China. It shows about 95% of students are able to adapt to an O2O blending teaching.
