A Study On The Curriculum Design Of Artificial Intelligence "Speech Recognition" In Junior High School

The era of artificial intelligence is gradually accelerating,and it has had a strong impact on our production,life,learning and other aspects.Looking at the world,developed countries such as the United States,Britain,France,Japan,and Germany have paid special attention to artificial intelligence.The training of professional talents to ensure that they occupy an advantage and dominant position in the global and market-oriented technological competition.my country also proposes to train high-end artificial intelligence talents to prepare for my country's transformation into a technological power.The young generation is not only the leader and main force of the country's economic and social development,but also the foundation of talent training.Therefore,the research and opening of artificial intelligence courses in the basic education stage is of vital importance.In recent years,the Ministry of Education of my country has successively issued a number of related documents to actively promote the popularization and development of artificial intelligence education in primary and secondary schools.At this stage,the information technology curriculum standards implemented in primary and secondary schools in my country have also added artificial intelligence-related modules to guide the development and practice of artificial intelligence education-related courses.Under the call of national policies,schools and educational institutions all over the country have launched the practice of artificial intelligence courses and the development of teaching materials,and artificial intelligence education in primary and secondary schools has begun to flourish everywhere.At present,although many achievements have been made in artificial intelligence education in primary and secondary schools in our country,it is still in the preliminary exploration stage on the whole,so some problems are inevitably exposed,such as:the curriculum content does not meet the characteristics of students' cognitive development and the orientation of curriculum goals There are deviations,lack of systematic design,single and inefficient course evaluation,and traditional teaching methods are backward.In general,there are still many difficulties in the establishment of artificial intelligence courses in primary and secondary schools in my country.There is a lack of experience in curriculum construction and practical application.What should artificial intelligence courses teach?How to teach and how to test?These difficult issues have yet to be resolved.This thesis adopts literature survey,questionnaire and experimental research methods.The main research contents are as follows:1.Investigation of the status quo of artificial intelligence education in junior high school and analysis of existing problems.The author first analyzes the current situation of artificial intelligence education in primary and secondary schools from four aspects:curriculum standards,curriculum implementation status,research trends and research hotspots,and existing textbooks,and then summarizes the existing problems of artificial intelligence education in junior high schools in my country based on the current situation analysis.2.Based on the five core concepts of artificial intelligence proposed by the American AI4K12 education action,design the knowledge distribution and learning goals of artificial intelligence courses in the junior high school stage,and put forward new strategies in the construction of artificial intelligence courses in junior high schools.The AI4K12 education initiative in the United States proposes to divide the artificial intelligence knowledge that needs to be learned at the k-12 stage into five themes:perception,representation and reasoning,machine learning,human-computer interaction,and social influence.The relevant teaching content and graded learning goal design in this action have a good reference and promotion for the development of artificial intelligence curriculum education in primary and secondary schools in my country.The author first interprets the connotation of the five concepts,and then summarizes and screens the corresponding key knowledge under the five concepts Finally.combined with the description of the learning goals under the five concepts of the junior high school stage,design the knowledge distribution of the artificial intelligence curriculum at the junior high school stage and the curriculum goal decomposition table.3.The selection and design of the evaluation content and evaluation methods of artificial intelligence teaching in junior high schools,and choose the appropriate evaluation methods according to different types of knowledge.In this research,teaching evaluation is divided into three aspects:concept understanding,practical application,and concept awareness,and different evaluation methods are designed for different types of knowledge content.For conceptual understanding knowledge,multiple choice questions,fill-in-the-blank questions,true judgment questions and other test questions can be used.For practical application,test questions that combine analysis questions,error correction questions,and connection questions can be used and combined.Submit project works,group presentations and other forms.Conceptual awareness can be evaluated in the form of questionnaires,scales,and debate competitions.The evaluation part of the case design is designed by a combination of multiple question types.After the course is practiced,the scores of the students'test papers are analyzed.The results show that this design can accurately analyze the students'understanding of artificial intelligence concepts and programming.The level of practice and learning attitudes and values.4.Design a junior high school artificial intelligence curriculum teaching model based on the PBL teaching method.Based on this model,carry out the case design of the junior high school artificial intelligence curriculum,and carry out classroom practice to test the effectiveness of the PBL teaching method in the junior high school artificial intelligence curriculum.Based on the current status and problems of the teaching methods of artificial intelligence in junior high schools,the author puts forward the teaching method of artificial intelligence in junior high schools based on PBL teaching method in combination with related research,designs the teaching mode of artificial intelligence courses in junior high schools,designs case based on teaching mode and conducts teaching practice to test the teaching The effectiveness of the model.
