INTRODUCTION

1. Rationale

In the world, many countries have chosen English as their second language. In

keeping with the development of the times, in addition to implementing the project

of teaching and learning foreign languages in the national education system, the

Ministry of Education and Training encourages schools to have bilingual classes in

science subjects such as Math, Chemistry, Physic…

Improving English language skills in English for high school students will

help students improve their knowledge, research, make good use of opportunities

and be able to think scientifically.

Through advanced English teaching, the knowledge and teaching capacity of

upper secondary school teachers are increasingly advanced, with access to the

knowledge that advanced countries are teaching. Therefore, the project “Teaching

and learning foreign languages in the national education system in the period 2008 –

2020” was approved by the Prime Minister on 30/9/2013. This is to aim at

comprehensively renovating the teaching and learning of foreign languages in the

national education system, implementing new curricula and teaching programs at all

levels. It is expected that by 2015, a significant progress will be made in the level of

proficiency in the use of foreign languages in human resources, especially in some

priority areas. By 2020, most of Vietnamese youths graduating from secondary

schools, colleges and universities have the ability to speak foreign languages

independently, confidently in communication, learning, working in an integrated,

multilingual and multicultural environment; 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 11th

grade to research.

2. Aims of the study

- Design of English electronic lectures for teaching chapter “Electromagnetic

induction”, Physics 11th grade to develop foreign language skills for students.

- Design of English lesson plans for teaching chapter “Electromagnetic

induction”, Physics 11th grade

- Design study card and consolidation exercise.

- Evaluate the quality of electronic lectures.

3. Research tasks

- Research the theoretical and practical basis of the topic.

- Design of English electronic lectures for teaching chapter “Electromagnetic

induction”.

4. Subjects and scope of the study

- The content of the chapter “Electromagnetic induction” in Physics 11th grade

and similar content in English.

- Research scope: Chapter “Electromagnetic induction” in Physics 11th grade.

5. Methods of study

- Theoretical research method: Research related material to the topic.

- Practical research methods: Rubric.

- Consult expert

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.
