Evaluating education through big data
Radar charts, bar charts, data tables ... In Qingyang District, Chengdu, Sichuan, the report cards obtained by primary school students are no longer just score tables, but subject evaluation reports including knowledge application, skill application and ability tendency, as well as hundreds of data of 16 indicators. These data are generated by ACTS (Academic Quality and Ability Evaluation System) academic evaluation technology in Qingyang District, which can not only reflect the information that students have reached the standard, but also provide the information that students compare with groups and others. "The advantages and disadvantages of children's long and short boards are clear at a glance." Yao Min, deputy director of Qingyang Education Bureau, said.

"Even if the scores of the two children are exactly the same, the scores presented by ACTS are quite different." Wu, a mathematical researcher at Qingyang Academy of Educational Sciences, introduced that ACTS academic evaluation technology aims at "knowledge and skills, processes and methods, emotions, attitudes and values" proposed by the new curriculum standards in China, and combines the relevant research results of pedagogy and psychology to form a three-dimensional measurement and evaluation model of "knowledge, skills and abilities", which can comprehensively examine students' comprehensive quality. "Academic transcripts are like medical examination and diagnosis. Through data analysis, students' strengths and weaknesses can be accurately obtained, and the right medicine can be better. Chen Tao, a Chinese teaching researcher at Qingyang Institute of Educational Sciences, said.

Last September, Tian Migang, a Chinese teacher at Paulownia Primary School in Chengdu, took over a class. Through the configuration evaluation of ACTS, she found out the situation of each student. "For example, the problem of Li Xiaohui (pseudonym) is that the level of language understanding is not good enough and the comprehensive generalization ability is weak." Tian Mi prescribed the right medicine. When it comes to generalizations, Li Xiaohui or children with similar questions are chosen to answer first, and then other students add, "After such targeted training, Li Xiaohui will improve bit by bit and step by step."

ACTS detection can not only generate personal reports of students, but also reports of classes, schools and regions, which can not only reflect the advantages and disadvantages of students, but also see the advantages and disadvantages of teachers and schools, help teachers improve teaching research and schools improve teaching management.

In the traditional evaluation method of "three rates and one point", teachers can only evaluate teaching according to the average grade, excellent rate, qualified rate and unqualified rate of the class, but according to the data of ACTS class, they can jump out of the mode of "lack of data and experience" and "fuzzy judgment and experience-oriented".

"The class newspaper is like a mirror, which can show the gains and losses of my usual teaching." After analyzing the class report, Zhang Qianying, a Chinese teacher at Zhanqi Branch of Chengdu Experimental Primary School, found that "students' generalization ability is seriously polarized, and their overall expression ability is not very good. "Therefore, Zhang Qianying adjusted the teaching methods in time." Ask a group of children to talk about the main content, and other children will judge and evaluate it. It not only cultivates the ability of generalization, but also exercises the ability of expression. "

Through the analysis of grade data, we can also grasp the overall situation of the school. "Any teacher with special skills will invite him to class, publicize his characteristics and experience, help teachers learn from each other's strengths and enhance the overall strength of the school." Chen Jie, principal of Chengdu Paulownia Tree Primary School, said.

In 20 12, Qingyang Education Bureau officially launched the reform of education quality evaluation, took the lead in setting up an education quality monitoring center in Chengdu, introduced the third-party evaluation technology, completely changed the evaluation purpose, content and method, and improved the existing education ecology. Qingyang District has established a self-circulation system of "teaching management, teaching research and teaching" through reform. Dai Zhiyong, secretary of Qingyang District Party Committee, said that Qingyang District should take this as a breakthrough, gradually change the utilitarian tendency and score orientation in the evaluation of education quality, and constantly promote the transformation from "learning to teaching".
