In Vietnam, what does electromagnetic wave mean?

Electromagnetic waves are the combination of oscillating electric and magnetic fields that are perpendicular to each other, propagating through space-like waves. To put it simply, electromagnetic waves are the propagation of electromagnetic energy through space.

*Main Characteristics of Electromagnetic Waves:

Transverse waves: The oscillation direction of the electric field and the magnetic field is perpendicular to the direction of wave propagation.

Propagation speed: In a vacuum, electromagnetic waves propagate at the speed of light (approximately 3 x 10^8 m/s).

Propagation without requiring a medium: Electromagnetic waves can propagate in a vacuum, unlike mechanical waves.

Attached energy: Electromagnetic waves carry energy and can transmit this energy to other objects.

Polarization: Electromagnetic waves can be polarized, meaning the oscillation of the electric field occurs in a specific direction.

*Examples of Electromagnetic Waves:

Light: Visible light is a form of electromagnetic waves.

Radio waves: Used in radio communication, television, mobile phones.

X-rays: Used in medicine for X-ray imaging.

Gamma rays: Have very high energy and are used in cancer treatment.

Ultraviolet rays: Present in sunlight, causing tanning.

What is the grade in which students will study electromagnetic waves in Physics in Vietnam?

Under Section 5 of the general education program for Physics issued with Circular 32/2018/TT-BGDDT, the content framework of the new Physics program is as follows:

Electromagnetic Waves

- State that in a vacuum, all electromagnetic waves propagate at the same speed.

- List the wavelengths of major radiations in the electromagnetic spectrum.

Magnetic Flux;

Electromagnetic Induction

- Define magnetic flux and the unit weber.

- Conduct simple experiments to illustrate the phenomenon of electromagnetic induction.

- Apply Faraday's law and Lenz's law on electromagnetic induction.

- Explain some simple applications of electromagnetic induction.

- Describe the electromagnetic wave model and apply it to explain the formation and propagation of electromagnetic waves in the electromagnetic spectrum.

- Discuss and design a plan (or describe a method) to create alternating current.

- State: the period, frequency, peak value, effective value of alternating current and voltage.

- Discuss to state some applications of alternating current in life, the importance of adhering to safety rules when using alternating current in life.

Thus, according to the above regulations, the 11th-grade students in Vietnam will study electromagnetic waves in Physics.

What are the educational methods for the 11th-grade Physics program in Vietnam?

Under Section 6 of the general education program for Physics issued with Circular 32/2018/TT-BGDDT, the educational methods for the 11th-grade Physics program in Vietnam are as follows:

* EDUCATION METHODS

- General Orientation

The teaching methods of Physics are implemented according to the following general orientations:

+ Develop essential qualities, general competencies, and Physics abilities for students through practical activities, experiences, exploration, and understanding physical phenomena and processes in the natural world; apply knowledge and skills to identify and solve problems in practice.

Emphasize organizing students to self-study according to the plan and guidance of teachers, suitable to the psychological age and abilities of each student.

+ Flexible application of methods, techniques, and forms of teaching to promote positivity, initiative, creativity, and the students' knowledge and life experience in learning; avoiding one-way imposition, rote learning. Besides the main form of learning in classrooms or laboratories, organize experiential activities outside the classroom such as fieldwork, in production and business facilities, craft villages by class or student groups.

Emphasize the use of information and communication technology advantages and experimental devices in organizing learning activities for students.

+ Implement integrated education, especially integrating science, technology, engineering, and mathematics (STEM education); integrating environmental protection education, using energy efficiently, disaster prevention, adapting to climate change, meeting the sustainable development requirements of society.

- Orientation in forming and developing key qualities and general competencies

Physics significantly contributes to forming and developing the scientific worldview for students, creating opportunities for students to appreciate the beauty of nature through the system of physical laws, while educating students on civic responsibilities in respecting natural laws, knowing how to appreciate, preserve, protect, and interact with nature, in accordance with sustainable development requirements.

In practical activities, experiments, scientific exploration, along with the opportunity to acquire knowledge and practice skills, students also cultivate and develop many virtues such as carefulness, diligence, honesty, responsibility...

Self-management and self-learning capacities are formed and developed in Physics through practical activities, projects, designing and conducting physical measurements; especially in carrying out scientific inquiry activities.

In Physics, students are regularly required to carry out study projects, practical assignments, internships in groups.

When performing these learning tasks, students exchange, present, share ideas, and learning content. These are good opportunities for students to develop communication and cooperation skills.

Problem-solving and creativity are unique to scientific inquiry activities. In Physics, these capacities are formed, developed in proposing problems, planning, and executing plans to explore the natural world from a physical perspective - contents spanning from primary to high school levels and realized through practical and experiential circuits at different levels.

These abilities are also formed and developed through the application of Physics knowledge and skills to solve real-world issues.

- Orientation on developing Physics competence

To develop the capacity for understanding Physics, teachers need to create opportunities for students to use their existing knowledge and experience to participate in forming new knowledge and skills. Pay attention to organizing activities where students can express or describe in their own way, analyze, explain, compare, systematize, directly apply acquired knowledge and skills to successfully solve learning situations, problems; thereby, connect new knowledge and skills with previously acquired knowledge and skills.

To develop the ability to explore the natural world from a physical perspective, teachers need to employ some advantageous teaching methods such as: visual methods (especially practical, experimental...), problem-solving instructional methods, project-based learning methods... creating conditions for students to ask questions, identify issues to be explored, find evidence to analyze information, test predictions, hypotheses through conducting experiments, or searching for information from books, the Internet...; as well as focusing on exercises requiring critical thinking, creativity (open exercises with multiple solutions...), exercises with content related to reality reflecting the essence of Physics, reducing computational exercises...

To develop the capacity to apply learned knowledge and skills, teachers need to create opportunities for students to actively interact through the process of identification, proposing ideas, and solving problems by: making predictions and building hypotheses; planning implementations; searching for information through print and multimedia materials; collecting, storing data from experiments in the laboratory or observation in nature; analyzing, processing, evaluating data based on simple statistical parameters; comparing results with hypotheses, explaining, drawing conclusions; writing, presenting reports, and discussing; applying Physics knowledge and skills to provide reasonable feedback or successfully solve new situations, problems in learning and life.
