A Pedagogical Case Study Of Digital Laboratory Teaching To Develop Students’ Data Literacy

With the advent of the information age with sensor and computer technology as the core,information technology has entered the field of education,and digital experiments have also entered the physics classroom.Physics curriculum cultivates students’ core literacy on the basis of experiments,and cultivates students’ scientific inquiry ability through physical experiment inquiry.Data acquisition and processing,as a part of the scientific inquiry ability in the core literacy of physics discipline,plays an important role in the cultivation of students’ scientific inquiry ability.Under the background of the information age,high school students are required to have certain data literacy.Therefore,the author studies the case of digital sensor assisted physics experiment teaching in high school around data literacy.Firstly,the research background,domestic and foreign research status,research purpose and significance,as well as the used research methods of digital sensor experiment and data literacy are described.This paper defines related concepts such as data literacy from the perspective of digital information system and scientific inquiry,and takes constructivism learning theory and information processing learning theory as the theoretical basis.Through questionnaire survey,the implementation status of physics experiment and the use of digital sensor experiment in high school in County,Chifeng City were investigated.The investigation found that physics experiment was not paid attention to,digital experiment was less applied,and students’ data literacy was lacking.Secondly,from the perspective of cultivating students’ data literacy,data literacy is divided into three dimensions: data awareness,data processing and data interpretation.The digital sensor experiment process is determined according to the corresponding experimental process of each dimension,and several teaching strategies are proposed.They are: pay attention to the selection of data to obtain and process difficult content;Scientific use of digital sensor experimental data processing advantages;Using sensors to design experiments,training students to generate awareness of data;Use digital system to collect and describe data,develop students’ ability of data collection and description;Analyze and interpret data according to the results of digital system,and cultivate students’ ability of data analysis and interpretation.Finally,taking "Free Fall Motion" and "Exploring the Relationship between Acceleration,Force and Mass" as specific cases,according to the content of this section,the difficulties in acquiring and processing data,combined with the teaching strategy of digital sensor assisted high school physics experiment with data literacy,the digital sensor experiment process is set up according to the dimension of data literacy.The digital sensor experiment is integrated into the physics experiment teaching for teaching design to achieve the purpose of cultivating students’ data literacy.
