Eye Tracking:The Gaining Lens of Exploring Teachers'Professional Vision
Eye tracking,as a new technology and method to study human's visual perception and cognitive processes,has become a lens for exploring teachers'professional vision due to its advantages and potential that cannot be achieved by traditional research methods.In order to explore what kind of gaining value eye tracking can achieve in the research of teachers'professional vision,and what complementary methods are needed to overcome its limits,the research uses well-known national and international databases as the retrieval source,through the retrieval of subject word and the method of snowballing,based on strict standard,and finally,an in-depth analysis of 54 literatures that met the requirements was carried out.The study found that eye tracking has two application modes in the research of teachers'professional vision,that is,the ON mode and the IN mode,and can produce the following gaining values.First,it can locate accurately in teachers'gaze distribution and have an objective analysis of relevant factors affecting teachers'visual attention.Second,it is an efficient way of revealing teachers'visual attention in depth.Finally,it captures the visual attention process of teachers comprehensively when they try to understand the classroom.Of course,the method of eye tracking is not a panacea.In order to understand the specifiic object and deeply analyze the reasoning process accompanying teacher's gaze,methods such as video analysis,cued retrospective reporting,retrospective thinking aloud and interview are used as the complementary lenses.
