Paradoxes and Dissolution of Big Data Empowering Educational Evaluation—An Analysis Based on the Perspective of Media Theory
From the perspective of media theory,an analytical framework is constructed to identify the triple dilemmas of cognition,technology and media characteristics in educational evaluation.The cognitive paradox reveals the contradiction between enhanced perception and weakened understanding;the technological paradox demonstrates the conflict between the extension of intelligence and cognitive overload;and the media characteristic paradox reflects the contradiction between the depth of cold media and the superficiality of hot media.The reasons for the emergence of the paradox include the sensory imbalance caused by the supremacy of vision,the non-linear tension between technological development and cognitive adaptation,and the defect of data as a"hot medium".In order to solve the triple dilemma,three paths are proposed to change from technological governance to good governance:first,deepen the information screening and improve the information literacy of the subject of educational evaluation;second,build a technologically integrated educational culture to create a balanced teaching and learning ecosystem;and lastly,innovate the concept of governance,insisting on the unity of instrumental rationality and value rationality.
