What is the final academic topic in the 11th-grade Physics curriculum in Vietnam?

Under Section 5 of the General Education Program for Physics issued together with Circular 32/2018/TT-BGDDT, the final academic topic in the 11th-grade Physics curriculum in Vietnam is defined as follows:

Topic 11.1. Gravitational Field

Concept of the gravitational field

- Provide examples proving the existence of the Earth's gravitational force.

- Discuss (through diagrams, multimedia materials) and indicate: All objects with mass create a gravitational field around them; A gravitational field is a force field created by a mass, existing around a mass and exerting gravitational force on a mass placed within it.

Gravitational force

- Indicate: When considering the gravitational field at a point outside a uniform sphere, the sphere's mass can be regarded as concentrated at its center.

- Apply Newton's law of gravitation F = Gm1m2/r² for some simple motion cases within the gravitational field.

Gravitational field intensity

- Define gravitational field intensity.

- From the law of gravitation and the definition of gravitational field intensity, derive the equation g = GM/r² for simple cases.

- Apply the equation g = GM/r² to evaluate some simple phenomena regarding the gravitational field.

- State that at each location near the Earth's surface, within a not-too-high altitude range, g is constant.

Gravitational potential and gravitational potential energy

- Discuss (through images, multimedia materials) to define the gravitational potential at a point in the gravitational field.

- Apply the equation ϕ = - GM/r in simple cases.

- Briefly explain the geostationary satellite motion and derive the formula for the first cosmic velocity.

Topic 11.2. Communication by Radio Waves

Modulation

- Compare amplitude modulation (AM) and frequency modulation (FM).

- List the frequencies and wavelengths used in different communication channels.

- Discuss to deduce the relative advantages and disadvantages of AM and FM channels.

Analog signal and digital signal

- Describe the advantages of transmitting data in digital form over analog.

- Discuss to deduce: the transmission of voice or music involves analog-to-digital conversion (ADC) before transmission and digital-to-analog conversion (DAC) upon reception.

- Provide a brief overview of the digital communication system regarding analog-to-digital and digital-to-analog conversion.

Signal attenuation

- Discuss the impact of signal attenuation on the quality of transmitted signals; state the signal attenuation in dB and in dB per unit length.

Topic 11.3. Introduction to Electronics

Operational amplifier

- Discuss, propose, select methods and implement the following project:

+ Classify sensors based on operating principles, scope of use, economic efficiency.

+ Operating principles of: light-dependent resistor (LDR), thermistor.

+ Operating principles of sensors using: light-dependent resistor (LDR), thermistor.

+ Basic properties of an ideal operational amplifier (op-amp).

Output devices

- Discuss, propose, select methods and implement the following project on three output devices:

+ Operating principles of op-amp relay circuit.

+ Operating principles of op-amp LED circuit (light-emitting diode).

+ Operating principles of op-amp calibrated meter circuit.

+ Design some simple application circuits using output devices.

Sensing devices

- Participate in field trips (or through multimedia materials), discuss to state some main applications of sensing devices and their operating principles.

Therefore, according to the regulation mentioned above, the final academic topic in the 11th-grade Physics curriculum in Vietnam is:

Topic 11.3. Introduction to Electronics

What are the regulations on manners and attire of upper secondary school students in Physics classes in Vietnam?

Under Article 36 of the Charter of Lower Secondary Schools, Upper Secondary Schools, and Multi-level Schoolsissued with Circular 32/2020/TT-BGDDT, manners and attire of upper secondary school students must be as follows:

- Students must have appropriate, respectful, friendly and cultured manners and language that suit the moral values and lifestyle of secondary school students.

- Student’s attire must be proper, clean, tidy, appropriate for their age and convenient for learning and other activities at school. Depending on the capacity of each school, the school principal may decide whether to let students wear uniform and seek approval from the parent committee of the school.
