What is the type of problem "Find m for the equation to have two roots x1 x2 satisfying a given condition" under the 10th-grade Mathematics curriculum?
This type of problem is common in the Mathematics curriculum at the upper secondary level, especially at the upper secondary level. It requires you to find the value of the parameter m so that the equation (often a quadratic equation) has two distinct roots x1, x2, and these roots satisfy a certain condition.

What are the regulations on assessing the learning results for 10th-grade Mathematics in Vietnam?
Under Section 7 of the General Education Program for Mathematics issued with Circular 32/2018/TT-BGDDT:
- The assessment of the learning results for Mathematics aims to provide accurate, prompt information of value regarding the development of competencies and progress of students based on the requirements needed to be achieved at each grade and educational level;
Adjust teaching and learning activities to ensure the progress of each student and improve the quality of Mathematics education in particular and education quality in general.
- Combine multiple forms of assessment (process assessment, periodic assessment), using various methods (observation, performance recording, oral examinations, objective tests, essay tests, written tests, practical exercises, project-based learning products, real-world tasks,...) at appropriate times.
- Process assessment (or frequent assessment) is organized by the subject teacher, in combination with assessments from teachers of other subjects, the self-evaluation of the students being assessed, and evaluation from other students in the group, the class, or parents.
Process assessment accompanies the learning activities of students, avoiding separation between teaching and assessment processes, ensuring the goal of assessment for progress in students' learning.
- Periodic assessment (or summative assessment) primarily aims to evaluate learning objectives achievement.
Results from periodic and summative assessments are used to certify learning levels and recognize student achievements.
Periodic assessments are organized by educational institutions or through national examinations and assessments.
- Periodic assessment is also used for managing educational activities to ensure quality at educational institutions and for the development of the Mathematics curriculum.
- Assess students' competence through evidence showing their achievements during actions taken by students.
The evaluation process involves basic steps such as: determining the evaluation purpose; identifying necessary evidence; selecting appropriate evaluation methods and tools; collecting evidence; interpreting evidence and providing feedback.
- Focus on choosing methods and tools to evaluate competencies and elements of mathematical competence. To be specific:
+ Assess mathematical thinking and reasoning skills: methods and tools like questions (oral, written), exercises,... that require students to present, compare, analyze, aggregate, and systematize knowledge;
Apply mathematical knowledge to explain and reason.
+ Assess mathematical modeling skills: choose real-life situations triggering mathematical problems.
From this, students are required to identify a mathematical model (including formulas, equations, tables, graphs,...) for the situation presented in the problem;
Solve mathematical problems within the established model; express and evaluate solutions within the real-world context and improve the model if the resolution is unsuitable.
+ Assess mathematical problem-solving skills: use methods like encouraging students to identify situations, highlight, and explain problems to be solved;
Describe and explain the initial information, goals, and expectations of the problem situation being considered; collect, select, organize information and connect it with existing knowledge;
Use questions (may require oral or written answers) demanding students apply knowledge to solve problems, especially real-life issues; observe methods (such as checklists with predetermined criteria), observe learners during problem-solving;
Assess through practical work products (for instance, learning project products); reasonably focus on integrated assessment tasks.
+ Assess mathematical communication skills: use methods like requiring students to listen, understand, read, record (summarize), analyze, select, extract the basic, focal mathematical information from spoken or written texts;
Use mathematical language combined with common language in presenting, expressing, questioning, discussing, and debating mathematical content, ideas, and solutions in interaction with others.
+ Assess competence in using mathematical tools and resources: use methods requiring students to recognize the names, functions, specifications, preservation methods, advantages, and limitations of tools and resources for learning mathematics;
Explain how to use (appropriately) tools and resources for learning mathematics to perform learning tasks or to express mathematical reasoning and proofs.
When the teacher plans lessons, it is necessary to establish criteria and evaluation methods to ensure that at the end of each lesson, students achieve the basic requirements based on the established criteria before proceeding to further learning activities.
