In Vietnam, what doeschemical formula mean?

A chemical formula referstothe concise representation of xem bóng đá trực tiếp nhà cái composition and structure of a chemical substance. It indicates which elements form xem bóng đá trực tiếp nhà cái substance and xem bóng đá trực tiếp nhà cái ratio of atoms of each element in a molecule of that substance.

*Example:

Water: H₂O. This formula shows that a water molecule consists of 2 hydrogen atoms (H) and 1 oxygen atom (O).

Table salt (Sodium chloride): NaCl. This formula shows that a molecule of table salt consists of 1 sodium atom (Na) and 1 chlorine atom (Cl).

*Types of chemical formulas:

Molecular formula: Indicates xem bóng đá trực tiếp nhà cái number of atoms of each element in a molecule.

Structural formula: Indicates how xem bóng đá trực tiếp nhà cái atoms are bonded together in a molecule.

Simplest formula: Indicates xem bóng đá trực tiếp nhà cái ratio of xem bóng đá trực tiếp nhà cái number of atoms of elements in a compound.

*Note: xem bóng đá trực tiếp nhà cái information on what a chemical formula is should only be used for reference./.

What are xem bóng đá trực tiếp nhà cái regulations regarding xem bóng đá trực tiếp nhà cái characteristics of Chemistry subject in Vietnam?

Under Section, I of xem bóng đá trực tiếp nhà cái Appendix of xem bóng đá trực tiếp nhà cái General Education Program for Natural Sciences subject issued together withCircular 32/2018/TT-BGDDT, xem bóng đá trực tiếp nhà cái characteristics of Chemistry at xem bóng đá trực tiếp nhà cái upper secondary level (grades 10-11-12) are as follows:

Chemistry is a science within xem bóng đá trực tiếp nhà cái natural sciences, studying xem bóng đá trực tiếp nhà cái composition, structure, properties, and transformations of elements and compounds.

Chemistry closely combines theory and practice, serving as a bridge to other natural sciences such as physics, biology, medicine, and geology. Advances in chemistry are associated with xem bóng đá trực tiếp nhà cái development of new discoveries in xem bóng đá trực tiếp nhà cái fields of biology, medicine, and physics. Chemistry plays an important role in life and production, contributing to economic and social development. xem bóng đá trực tiếp nhà cái achievements of chemistry are applied to fields such as materials, energy, pharmaceuticals, biotechnology, agriculture, forestry, fisheries, and many other sectors.

In xem bóng đá trực tiếp nhà cái general education program, Chemistry is a subject within xem bóng đá trực tiếp nhà cái group of natural sciences at xem bóng đá trực tiếp nhà cái upper secondary level, selected by students based on career orientation, interests, and individual abilities. Chemistry helps students acquire core knowledge of chemistry and apply this knowledge to life while relating to many other educational fields.

Along with Mathematics, Physics, Biology, Informatics, and Technology, Chemistrycontributes to promoting STEM education, one of xem bóng đá trực tiếp nhà cái educational trends being valued in many countries around xem bóng đá trực tiếp nhà cái world.

xem bóng đá trực tiếp nhà cái content of xem bóng đá trực tiếp nhà cái Chemistry subject is designed into topics that ensure xem bóng đá trực tiếp nhà cái consolidation of content circuits, developing knowledge and practical skills formed from xem bóng đá trực tiếp nhà cái lower educational levels, while also helping students gain a deeper understanding of xem bóng đá trực tiếp nhà cái foundational chemistry knowledge, providing a basis for learning, working, and research.

For each academic year, students with career-oriented aspirations need to use more chemistry knowledge and select three study modules that are suitable to their own desires and xem bóng đá trực tiếp nhà cái organizational conditions of xem bóng đá trực tiếp nhà cái school.

These modules aim to meet xem bóng đá trực tiếp nhà cái deep differentiation requirements, helping students enhance knowledge and practical skills, applying learned knowledge and skills to solve real-world issues and meeting xem bóng đá trực tiếp nhà cái orientation requirements for their careers.

Under Section 7 of xem bóng đá trực tiếp nhà cái Appendix of xem bóng đá trực tiếp nhà cái General Education Program for Natural Sciences subject issued together withCircular 32/2018/TT-BGDDT, xem bóng đá trực tiếp nhà cái regulations on xem bóng đá trực tiếp nhà cái assessment of Chemistry education outcomes in Vietnamare as follows:

- xem bóng đá trực tiếp nhà cái objective of assessing education outcomes is to provide accurate, prompt, and valuable information about xem bóng đá trực tiếp nhà cái level of response to xem bóng đá trực tiếp nhà cái program's requirements and student progress to guide learning activities, adjust teaching activities, manage and develop xem bóng đá trực tiếp nhà cái program, ensure xem bóng đá trực tiếp nhà cái progress of each student, and improve xem bóng đá trực tiếp nhà cái quality of education.

- xem bóng đá trực tiếp nhà cái basis of assessment is xem bóng đá trực tiếp nhà cái required qualities and competencies as stipulated in xem bóng đá trực tiếp nhà cái overall program and xem bóng đá trực tiếp nhà cái chemistry subject program. xem bóng đá trực tiếp nhà cái assessment scope includes all content and requirements needed to be achieved in xem bóng đá trực tiếp nhà cái chemistry subject program.

- Forms, methods, and assessment tools:

+ Assessment form: Combining process assessment (regular assessment), summative assessment (periodic assessment), and large-scale assessments at national, local levels, and international assessments ensuring comprehensive, frequent, and integrated evaluation in teaching and learning activities by teachers and students.

+ Assessment methods and tools:

+ Combining teacher assessment with self-assessment and peer assessment by students. Coordinating situation assessment; assessment through testing; assessment via projects and portfolios; assessment through feedback and reflection; assessment through observation.

+ Combining xem bóng đá trực tiếp nhà cái assessment of learning products (essay tests, objective multiple-choice tests, oral answers, presentations, experimental practice exercises, research projects,…) with assessment through observation (attitudes and behavior in discussions, group work, experiments, field trips,…).

- Choosing appropriate methods and tools to assess a specific competency.

+ Assessing xem bóng đá trực tiếp nhà cái component of chemistry cognitive capability, questions (oral, written), exercises,... that require students to present, compare, systematize knowledge, or apply knowledge to explain, prove, and solve problems can be used.

+ Assessing xem bóng đá trực tiếp nhà cái component of exploring xem bóng đá trực tiếp nhà cái natural world from a chemical perspective, xem bóng đá trực tiếp nhà cái following methods and tools can be used:

++ Checklists or records of observation results by teachers according to predetermined criteria about xem bóng đá trực tiếp nhà cái execution of experiments and xem bóng đá trực tiếp nhà cái investigative tasks of students,...

++ Questions and tests aimed at evaluating students' understanding of experimental skills; xem bóng đá trực tiếp nhà cái ability to reason to conclude, verify options, process given data to infer conclusions; xem bóng đá trực tiếp nhà cái ability to design experiments or research to perform assigned learning tasks and propose appropriate devices and techniques,...

++ Reports ontest results, practice, conduct research projects,…

+ Assessing xem bóng đá trực tiếp nhà cái component of applying learned knowledge and skills, students can be required to present practical problems that need resolution, which must use chemical language, charts, models, experimental skills,... to describe, explain chemical phenomena in xem bóng đá trực tiếp nhà cái problem under consideration; use questions (which may require oral or written answers) that demand students to apply knowledge and skills to solve learning problems, especially real-world issues.
