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, Physics Therefore, the project “Teaching and learning foreign languages in the national education system in the period 2008 – 2020” was approved by the Prime lu Minister on 30/9/2013 This is to aim at comprehensively renovating the teaching an n va and learning of foreign languages in the national education system, implementing significant progress will be made in the level of proficiency in the use of foreign gh tn to new curricula and teaching programs at all levels It is expected that by 2015, a ie languages in human resources, especially in some priority areas By 2020, most of p Vietnamese youths graduating from secondary schools, colleges and universities nl w have the ability to speak foreign languages independently, confidently in d oa communication, learning, working in an integrated, multilingual and multicultural an lu environment; foreign languages become the strength of the Vietnamese people, va serving the progress of industrialization and modernization of the country [9] u nf At the present, some schools in the whole country have implemented Physics ll and some other science subjects teaching in English However, that is difficult m oi Schools must learn how to implement this pilot program The two biggest z at nh difficulties are the lack of qualified English teachers and the lack of standardized, z uniform programs As for teachers, schools are passive, have to train them, foster or gm @ find sources of rent, contracts from the outside are the main Except for a few l schools, teachers are trained abroad, trained, and taught in English as Le Quy Don m co High School, Tran Dai Nghia High School, and the rest are having the same difficulty [10] an Lu To overcome the status of teachers who not reach the bilingual level, ac th n va Physics teachers are not good at English Conversely, teachers who are good at si English not teach Physics Teachers teaching in English, the University of Education - University of Da Nang has started to apply the standard output level according to the framework of foreign language skills from the enrollment level of 2013-2017 and apply later Bilingual teaching in some subjects specialized for students 2014-2018, 2015-2019 Physics teaching in English will create the premise, foreign language skills for children participating in the International Olympic Games, the international contest of science and technology The teaching of natural sciences in general and Physics in particular in English is necessary for us to soon integrate into the world and at the same time to create an environment of striving for both students and teachers, give opportunities to improve professional qualifications, adopt quickly of new lu an knowledge However, Physics teaching in English materials such as textbooks, n va exercise books, electronic lectures are very limited Therefore, it is necessary to tn to design of English electronic lectures for Physics teaching, which will help teachers Starting from the above reasons, I chose the topic: “Design of English p ie gh to have additional materials and lectures w electronic lectures for
