The systematic review on the impact of blended learning on critical thinking, which included articles from 2018 to 2023, turned up 34 pertinent publications in 4 databases. A trend that can be detected in the review is as follows: First, blended learning is becoming more popular, according to the publisher. Second, rather than testing students' critical thinking dispositions, the majority of research focus on their critical thinking skills. Third, tests developed by researchers themselves are more frequently utilized to gauge students' critical thinking abilities. Fourth, from the perspective of TPACK (technological, pedagogical, and content knowledge), the use of technology in blended learning environments has been neglected and content knowledge has been limited to a few specific areas. In the ending part, several recommendations and suggestions for instructors and future research have been made.
