What is trực tiếp bóng đá k+ grade whose Mathematics curriculum in Vietnam covers trực tiếp bóng đá k+ Cosine formula?
Under Section 5 of trực tiếp bóng đá k+ General education program in Mathematics issued withCircular 32/2018/TT-BGDDT, trực tiếp bóng đá k+ content in trực tiếp bóng đá k+ 9th-grade Mathematics curriculum is as follows:
*Trigonometric Ratios in Right Triangles
Trigonometric ratios of acute angles. Some relationships regarding sides and angles in right triangles
- Recognize trực tiếp bóng đá k+ values of sine, cosine, tangent, cotangent of acute angles.
- Explain trực tiếp bóng đá k+ trigonometric ratios of specific acute angles (30°, 45°, 60°) and complementary angles.
- Calculate trực tiếp bóng đá k+ trigonometric ratios of acute angles, either exactly or approximately, using a handheld calculator.
- Explain some relationships regarding sides and angles in right triangles (e.g., trực tiếp bóng đá k+ length of a leg is equal to trực tiếp bóng đá k+ hypotenuse times trực tiếp bóng đá k+ sine of trực tiếp bóng đá k+ opposite angle or trực tiếp bóng đá k+ cosine of trực tiếp bóng đá k+ adjacent angle; trực tiếp bóng đá k+ length of a leg is equal to trực tiếp bóng đá k+ other leg times trực tiếp bóng đá k+ tangent of trực tiếp bóng đá k+ opposite angle or trực tiếp bóng đá k+ cotangent of trực tiếp bóng đá k+ adjacent angle).
- Solve some practical problems associated with trực tiếp bóng đá k+ trigonometric ratios of acute angles (e.g., calculating segment lengths, angle magnitudes, and applying right triangle problems, etc.).
Therefore, according to trực tiếp bóng đá k+ above regulations, trực tiếp bóng đá k+ 9th-grade Mathematics curriculum covers trực tiếp bóng đá k+ Cosine formula.
What are trực tiếp bóng đá k+ regulations on assessingthe educational outcomes for 9th-grade Mathematics in Vietnam?
Under Section 7 of trực tiếp bóng đá k+ General education program in Mathematics issued withCircular 32/2018/TT-BGDDT, trực tiếp bóng đá k+ assessmentof educational outcomes for9th-gradeMathematics in Vietnam is as follows:
trực tiếp bóng đá k+ goal of assessing trực tiếp bóng đá k+ educational outcomes of Mathematics is to provide accurate, prompt, and valuable information on students' capacity development and progress based on trực tiếp bóng đá k+ requirements for each grade and level of education; adjusting teaching activities, ensuring each student's progress, and enhancing trực tiếp bóng đá k+ quality of Mathematics education in particular and overall educational quality.
Combine multiple assessment forms (process assessment, periodic assessment), multiple assessment methods (observation, recording trực tiếp bóng đá k+ implementation process, oral questioning, objective tests, essays, written exams, practical exercises, study projects/products, real-world task execution,...) and at appropriate times.
Process assessment (or continuous assessment) is organized by trực tiếp bóng đá k+ subject teacher, combined with assessments by other subject teachers, self-assessment by trực tiếp bóng đá k+ assessed student, and assessments by other students in trực tiếp bóng đá k+ group, class, or by parents. Process assessment goes hand in hand with trực tiếp bóng đá k+ learning activities of students, avoiding separation between teaching and assessment processes, and ensuring trực tiếp bóng đá k+ assessment goal of student progress in learning.
Periodic assessment (or final assessment) primarily aims to assess trực tiếp bóng đá k+ achievement of learning goals. Periodic and final assessment results are used to certify learning levels and recognize student achievements. Periodic assessments are organized by educational institutions or through national examinations and assessments.
Periodic assessments are also used to manage teaching activities, ensuring quality in educational institutions and supporting trực tiếp bóng đá k+ development of trực tiếp bóng đá k+ Mathematics program.
Assess student capacity through evidenced outcomes during trực tiếp bóng đá k+ execution of student actions. trực tiếp bóng đá k+ assessment process includes basic steps such as: determining assessment purposes; identifying necessary evidence; selecting appropriate methods and tools; collecting evidence; interpreting evidence and providing remarks.
Focus on selecting methods and tools to assess components of mathematical capability. To be specific:
- Assess mathematical thinking and reasoning skills: use methods and tools such as questions (spoken, written), exercises,... that require students to present, compare, analyze, aggregate, and systematize knowledge; apply mathematical knowledge to explain and reason.
- Assess mathematical modeling capabilities: select real-life situations that give rise to mathematical problems. From there, require students to identify trực tiếp bóng đá k+ mathematical model (including formulas, equations, tables, graphs,...) for real-world situations; solve mathematical problems within trực tiếp bóng đá k+ established model; represent and assess solutions in practice and improve trực tiếp bóng đá k+ model if trực tiếp bóng đá k+ resolution is unsuitable.
- Assess problem-solving capabilities in mathematics:
+ Use methods that require learners to identify situations, detect and present problems to be solved; describe, explain initial information, objectives, and expectations of trực tiếp bóng đá k+ context;
+ Collect, select, organize, and connect information with existing knowledge; use questions (which may require oral or written responses) that require learners to apply knowledge to solve problems, especially practical ones; use observation methods, observe learners during problem-solving; assess through learners' practice products; reasonably consider integrated assessment tasks.
- Assess mathematical communication skills: use methods such as requiring learners to understand, read, take notes (summarize), analyze, select, and extract key mathematical information in spoken or written texts; use mathematical language combined with regular language to present, express, ask questions, discuss, and debate mathematical content, ideas, and solutions while interacting with others.
- Assess theability to use tools and means for learning mathematics: use methods such as requiring learners to recognize trực tiếp bóng đá k+ name, usage, form, maintenance, advantages, and limitations of mathematical learning tools and means; present trực tiếp bóng đá k+ (appropriate) use of tools and means for learning mathematics to perform learning tasks or explain mathematical reasoning and proofs.
When preparing lesson plans, they mustset assessment criteria andmethods to ensure students achieve basic requirements based on given criteria before proceeding with further learning activities.
