What is xem bóng đá trực tiếp vtv2 perspective on constructing xem bóng đá trực tiếp vtv2 Chemistry curriculum in Vietnam?
Based on Section 2 of xem bóng đá trực tiếp vtv2 Chemistry Education Program issued together withCircular 32/2018/TT-BGDDT, xem bóng đá trực tiếp vtv2 perspective on constructing xem bóng đá trực tiếp vtv2 Chemistry curriculum for classes (including grade 10) is as follows:
xem bóng đá trực tiếp vtv2Trong chương trìnhin Chemistry fully adheres to xem bóng đá trực tiếp vtv2 regulations stated in xem bóng đá trực tiếp vtv2 general program, while emphasizing xem bóng đá trực tiếp vtv2 following perspectives:
(1) Ensuring inheritance and development
- xem bóng đá trực tiếp vtv2 Chemistry program inherits and promotes xem bóng đá trực tiếp vtv2 strengths of xem bóng đá trực tiếp vtv2 current program, absorbs xem bóng đá trực tiếp vtv2 experience of curriculum construction from countries with advanced education systems in xem bóng đá trực tiếp vtv2 world and xem bóng đá trực tiếp vtv2 region; at xem bóng đá trực tiếp vtv2 same time, it integrates achievements in educational science, chemical science suitable to students' cognitive levels and psychological age, taking into account xem bóng đá trực tiếp vtv2 socio-economic conditions of Vietnam.
- xem bóng đá trực tiếp vtv2 Chemistry program inherits and develops xem bóng đá trực tiếp vtv2 educational content of Natural Sciences at xem bóng đá trực tiếp vtv2 lower secondary level through a concentric structure combined with a linear structure to expand and enhance knowledge and skills for students.
At xem bóng đá trực tiếp vtv2 lower secondary level, through xem bóng đá trực tiếp vtv2 Natural Sciences subject, students get acquainted with some basic chemical knowledge at a qualitative level, visually descriptive.
At xem bóng đá trực tiếp vtv2 upper secondary level, xem bóng đá trực tiếp vtv2 Chemistry subject focuses on equipping students with foundational chemical knowledge about xem bóng đá trực tiếp vtv2 structure, properties, and applications of simple substances and compounds to explain xem bóng đá trực tiếp vtv2 nature of chemical changes to a necessary extent.
(2) Ensuring practicality
xem bóng đá trực tiếp vtv2 Chemistry program prioritizes practicality; avoids a tendency towards excessive calculation; focuses on equipping students with tool concepts and xem bóng đá trực tiếp vtv2 method of using tools, especially helping them gain practical laboratory skills, xem bóng đá trực tiếp vtv2 ability to apply chemical knowledge to understand and solve some practical problems to a certain extent, meeting xem bóng đá trực tiếp vtv2 demands of life.
(3) Implementing career-oriented education
xem bóng đá trực tiếp vtv2 Chemistry program concretizes career-oriented educational goals. Based on identifying fields and processes that require deep chemical knowledge, xem bóng đá trực tiếp vtv2 program selects core educational content and study topics to help students explore more deeply into chemical knowledge with numerous practical applications, thus preparing them for career orientation.
(4) Promoting student activeness
xem bóng đá trực tiếp vtv2 educational methods of xem bóng đá trực tiếp vtv2 Chemistry subject contribute to promoting student activeness, initiative, and creativity, aiming to develop chemical competency and contribute to developing key qualities and general competencies as stated in xem bóng đá trực tiếp vtv2 general program.
