This research aimed to develop a model of a collaborative blended learning (CoBl) to develop learning achievement and thinking ability of undergraduate students in the Institute of Physical Education. The research is divided into three phases using the blended learning model via collaborative learning with thinking abilities approach as follows: Phase 1 consists of the development of the collaborative blended learning model; phase 2, the effects of implementing from the model to develop thinking abilities; phase 3, the presentation of the developed model to a group of experts for accepting the developed model. The findings showed that: there are four components in the model of collaborative blended learning namely principles, objectives, procedures and instructional activities, and measurement and evaluation. The instructional processes are divided into 3 phases, namely, preparation, learning management, and measurement and evaluation. The experimental group of students showed gains in learning achievement and thinking abilities as a whole and in each subscale from before learning with the developed model at the 0.05 level of significance. They showed greater learning achievement than the control group of students (p = 0.001). However, the two groups of these students did not statistically indicate different thinking abilities (p = 0.501). In addition, the students showed their opinions about learning with the developed model at the high agreed level. Also, the experts assessed the developed model at the most appropriate level.
