An Experimental Study On Cognitive Development Of Senior High School Students Under CTCL Paradigm

Based on the research paradigm of Learning Technology(CTCL),this study takes the content of "the nature of logarithmic function" in senior high school mathematics as an example,and takes the cognitive state as the breakthrough point to carry out the experimental teaching of technology promoting learners' cognitive development.This study focuses on the following three questions:(1)whether the "cognitive state" of learners in the process of classroom learning can be measured;(2)whether the "cognitive state" of learners in class can be intervened through technology to improve their academic performance;(3)how the technology intervention in class can change the cognitive state of learners and promote the cognitive development of learners.Based on the above three research questions,this study carried out the following five parts through questionnaire survey and quasi experimental research methods: first,a group of learners were used to test and classify the cognitive state before class,and the corresponding information was collected for the preparation of pre-test and post-test;second,the other two groups(experimental group and control group)were used to carry out the pre-test and obtain the learning results.At the same time,the homogeneity of the subjects is tested;third,according to the data obtained from the test and pre-test,the possible cognitive states of the experimental group and the control group are predicted,and a group of homogeneous learners are used to verify the prediction.At the same time,the author choose the technology needed in the experimental teaching,and design the learning resources;fourth,implement the experimental teaching for the experimental group and the control group,and implement the post-test after the end of the teaching.The experimental group will receive additional real-time intervention based on the cognitive state in class,while the control group will not;fifthly,the data will be processed and comprehensive analysis will be conducted to draw research conclusions based on all the research problems.Through the research of the above five parts,the author finds that based on the research paradigm of Learning Technology(CTCL),adding in-class test(hereinafter referred to as "in-class test")aiming at learners' current cognitive state in the teaching process and real-time intervention can promote learners' academic performance and cognitive development.Three conclusions are obtained in this study:(1)The cognitive state in the process of classroom learning can be measured by technical means.(2)Real time intervention for learners' cognitive state in class can improve their academic performance.(3)The technology intervention in class has consolidated the development trend of cognition and promoted the cognitive development of learners.
