Foreigns languages become the strength of the Vietnamese people, serving the progress of industrialization and modernization of the country [9] However, science teachers in general English and physics in particular are facing many difficulties, such as program-oriented issues, learning materials, methods and forms of organization To help teachers have an overview of materials search, composition, teaching and research for students, to effectively teach physics in high school curricula in English Starting from the above reasons, I chose the topic: “Design of English electronic lectures for teaching chapter “Electromagnetic induction”, Physics 11 grade to research Aims of the study Design of English electronic lectures for teaching chapter “Electromagnetic - th induction”, Physics 11 grade to develop foreign language skills for students Design of English lesson plans for teaching chapter “Electromagnetic - th induction”, Physics 11 grade - Design study card and consolidation exercise - Evaluate the quality of electronic lectures Research tasks - Research the theoretical and practical basis of the topic - Design of English electronic lectures for teaching chapter “Electromagnetic induction” Subjects and scope of the study th The content of the chapter “Electromagnetic induction” in Physics 11 grade and similar content in English - th Research scope: Chapter “Electromagnetic induction” in Physics 11 grade Methods of study - - Theoretical research method: Research related material to the topic - Practical research methods: Rubric Consult expert - th CONTENTS CHAPTER I: LITERATURE REVIEW AND PRACTICAL RESEARCH 1.1 Theoretical background of teaching the natural sciences subjects in English 1.1.1 Levels of teaching the natural sciences subjects in English Teaching science in English is beneficial to the development of the brain of students, helping them to have better memory, better concentration, and the ability to get rid of irrelevant information Where English is not the mother tongue, teaching science in English is carried out gradually by three levels: - Level 1: Teachers provide some Physics terms in English for students Then teachers teach in the classroom, communicate mainly in Vietnamese In this way, students will not be able to develop important skills in learning English, such as speaking, writing and communication skills - Level 2: Bilingual teaching - simultaneous 50% English and 50% Vietnamese This approach is often used in complex situations, which are too new for students to catch up and fail to grasp the content of the problem - Level 3: Teaching and organizing activities entirely in English.This method is often used when the level of students is the same and the content is not too complicated but relatively familiar with the students By maximizing the use of this method, students will have the opportunity to improve their English language skills [2] 1.1.2 The roles of teaching the natural sciences subjects in English English is an international language widely used in wide variety of fields including science, technology and education Therefore, English is a tool for us to access advanced education and modern science and technology Vietnam is a developing country and international integration which help us to improve the efficiency of education and training, exchange and apply advanced technologies in the world II THE PHENOMENON OF SELF-INDUCTION Light is immed iately light is lit slowly When the K is closed, i through branch increases suddenly, then the soleno id appeared i obstructs the increase of i through L Therefore light increase slowly II THE PHENOMENON OF SELF-INDUCTION Experiment 2: The K2 , K3 opened, when we closed K, why did the light brightens before it is put out? 10 88 II THE PHENOMENON OF SELF-INDUCTION  Ф  an When we closed K, i i appears in the solenoid with the same direction with the initial iL  i flows through the light, making the light brighten before it is put out 11 AI THE PHENOMENON OF SELF-INDUCTION Definition: Self-induction is the phenomenon of electromagnetic induction happening in an electric circuit The magnetic flux variation through that circuit is caused by the variation of the current in the circuit 12 89 II THE PHENOMENON OF SELF-INDUCTION When did the phenomenon of self –induction appear? In DC circuit: When the circuit is closed, opened In AC circuit: When I varies continuously over time 13 THE PHENOMENON OF SELF-INDUCTION SELF-INDUCED ELECTROMOTIVE FORCE BI IV AI SPECIFIC MAGNETIC FLUX OF A CLOSED CIRCUIT APPLICA TIONS SELF - INDUCTION I 14 90 SELF-INDUCED ELECTROMOTIVE FORCE BI What is the self-induced electromotive force? The electromotive force generated by the inductance phenomenon is called the self-induced electromotive force 15 BI SELF-INDUCED ELECTROMOTIVE FORCE c We have: and t c L it ∆Ф = L.∆i The self-induced electromotive force has the magnitude proportional to the variable speed of the current in the circuit 16 91 BI SELF-INDUCED ELECTROMOTIVE FORCE When a current I flows through a self-induced solenoid, the solenoid gathers an energy: W L.i2 L : inductance ( H) i : Speed of the current through the solenoid (A) W : The magnetic field energy (J) 17 IV APPLICATIONS Transformer Inductor 18 92 SUMMARY (C) have the current i Specific magnetic flux = Li Self-induced electromotive force SUMMARY Choose true or false for the following statements: TRUE a L only depends on the structure and size of the closed circuit (C) b Self-induction is the phenomenon of electromagnetic induction happening in an electric circuit c In DC circuit, there is always appear a phenomenon of self-induction d In AC circuit, there is always appear a phenomenon of self-induction 3.2 The rubric to evaluate the quality of electronic letures 93 FALSE QUALITY ASSESSMENT FORM OF ELECTRONIC LECTURES With the aim of improving the quality of teaching science in English, we have conducted the topic "Design of English electronic lectures for teachingẾT th KEEchapter Electromagnetic induction", Physics 11 grade" We hope the teacher will help us complete the quality assessment of the delivered eLearning Teacher marks "X" in the boxes Teacher’s name: ………………………………………… Work in school: ………………………………………… Evaluation level: Very good/ Very suitable Criteria of the content Criteria Lesson 1.1 Ensuring standard of knowledge, skills of the program 1.2 Ensuring the accuracy of the content of knowledge, in accordance with the subject and method of teaching The slide is not too much, the content between the slides are logic and tight 1.3 Provide vocabulary and syllabus accordant with the content of the unit 1.4 Presentation of core knowledge, The opened questions appropriate to the content of the lesson Exercises are reasonably designed 1.5 The lecture has visual and animated images in accordance with the lecture content, creating excitement and impression for students 1.6 The English videos demonstrate the lively content of the lesson, clarify the focus of the lesson and help students to practice listening 94 Criteria of the form Criteria 2.1 Beautiful and intuitive presentation, highlighting knowledge Pictures are clear, sharp, text large enough to see 2.2 The interface is friendly, aesthetically pleasing, suitable for the student age, creating a sense of excitement in learning Technical criteria Criteria 3.1 Use of Video, Audio, Image, Flash, Embed, Link,… 3.2 The teacher mastered manipulation smoothly, the presentation did not malfunction 3.3 The pace of the presentation and the delivery of the unit is moderate, consistent with the ability of the majority of students Students follow and write the lesson on time Effective criteria Criteria 4.1 Implementing teaching objectives 4.2 Students are active and interested in learning 4.3 Students are improved the skills of listening, speaking, reading and writing in English 4.4 Promote the outstanding effect of IT which black boards and other teaching materials are difficult to achieve the technique, 95 CONCLUSION AND RECOMMENDATION Conclusion: Theoretically, through the process of finding and researching the subject "Design of English electronic lectures for teaching chapter Electromagnetic induction", Physics 11 th grade, I have obtained some pedagogical conclusions as follows: - Teaching Physics in English will help students to learn both English and Physics at the same time - Successfully design lesson plans, electronic lectures, study card in English for th lessons in chapter “Electromagnetic induction”, physics 11 grade: + Magnetic flux Electromagnetic induction + Induced electromotive force + Self-induction In fact, I watched and got two lessons include "Magnetic flux Electromagnetic th th induction" physics 11 grade and "Structure of matter" physics 10 grade tought by Tran Thi Anh Dao, teacher in Le Quy Don gifted high school in Da Nang In the teaching process in English, teachers and students interact well with each other, is the integration between the knowledge of physics and the knowledge of English The knowledge is sequenced, examples are illustrated concisely and condensed, and orientation questions help students find their own answers with clear and fluent English expressions Thus, teaching English in physics is going in the positive direction However, in order to have such good teaching hours, teachers need to improve their listening and speaking ability and in particular maximize the role of English electronic lectures for teaching activities in order to improve quality education Recommendation: Through the process of research I have some recommendation as follows: 96 - Teachers need to find effective learning methods to become teachers teaching physics in good English - Teaching English as a second language in the university aims to train teachers in both physical and linguistic specializations 97 REFERENCES Tiếng Việt [1] Nguyễn Thị Trúc Nguyên (2014), Nghiên cứu phương pháp dạy học hóa học tiếng Anh trường THPT (Áp dụng cho chương trình hóa 11), Luận văn thạc sĩ khoa học Giáo dục [2] Dương Lệ Hồng (2014), Nghiên cứu phương pháp dạy học hóa học tiếng Anh trường THPT (Áp dụng cho chương trình hóa 10), Luận văn thạc sĩ khoa học Giáo dục [3] Pham Kim Chung (10/2017), Tổ chức dạy học môn khoa học tự nhiên tiếng Anh cho học sinh trường trung học phổ thơng, Tạp chí Khoa học Giáo dục [4] Nguyễn Thị Hộp (2017), Thiết kế giảng điện tử song ngữ Anh -
