Vieta’s formulas have many applications in the general mathematics program in Vietnam. Indeed, they appear in many forms of mathematical problems, ranging from 9th, 10th and 12th grades. The complexity of the mathematical problems makes students commit many errors when using the Vieta’s formulas to solve them. The sample consisted of 246 students in grades 10 and 12, in which they addressed four questionnaires related to Vieta’s formulas. The results were quite unexpected because the errors of tenth graders also existed for 12th grade students for many different reasons.

Analysis of Cambodian Students' Errors in Solving Quadratic Function Problems Using Newman's Error Analysis2023 •
Errors and misconception in students' mathematics learning have become hot topics for teachers, educators and researchers for decades. Consistent errors may lead to misconception which ultimately affect the students' learning performance. This study centered on errors made by the students when they attempted to solve mathematics word problems. The objective of this study was to identify the errors the students made in solving quadratic function word problems. Qualitative method with students' test paper analysis and the in-depth interview using Newman's Error Analysis (NEA) framework were used to identify the students' errors and mistakes. Forty grade 12 students studying in a Cambodian public high school participated in the study. It was found that the students made the most errors in comprehension level (36.2%), reading errors accounted for 2.15% while transformation errors made up of 12.27%. Process skills errors made up of 19.94% while encoding errors (29.44%) ranked second among errors the students made. Failure to know or understand individual mathematical concept, for example vertex, symmetry line, interception point, range and domain of function etc. had hindered the students' comprehension of the problem and led to difficulties in solving math problems. This study suggested careful attention should be taken into account when introducing specific mathematics concept to students, especially at the early stage. Emphasizing the

Mathematical Representations: A Study in Solving Mathematical Word Problems at Grade 5 - Vietnam2019 •
The paper aims to: (1) present the types of representations in solving mathematical problems;(2) to find out the types of representation used in solving word problems in textbook “Toan 5” (Mathematics 5) of Vietnam; and (3) report the results of a survey on using representations of Grade 5 students in solving non-routine mathematical problems. The study results revealed that the students faced many difficulties and had errors sin using visual and symbolic representation.

Analysis of Student Errors in Solving Mathematics Problems at Muhammadiyah Senior High School Special Program of Kottabarat Surakarta City2021 •
Learning mathematics is a crucial part of education. Mathematics is one of the subjects feared by students. One of the problems in the object of mathematics study is the material for X class of Senior High School. Students of grade X are undergoing adaptation from the junior high school level to the high school level so that the findings of conceptual errors, calculations, and thinking patterns in problem-solving algorithms are often found. This also happened to the students of the Muhammadiyah Senior High School Special Program of Kottabarat Surakarta. In connection with the above problems, the author analyzes student errors in solving math problems at the Muhammadiyah senior high school special program of Kottabarat Surakarta.This study aims to find out errors, causes of error, and alternative problem solving related to students' errors in solving math problems. This research is qualitative descriptive research. The research subjects were taken by sampling purposes. they are ...
In Vietnam, secondary school students learn the equation of a circle in Grade 10. Based on how to present this equation in the textbook “Geometry 10” and types of task for students, we believe that some limitations happen to students when they solve problems related to the equation of a circle. This paper reports the investigation of 845 students from the Mekong Delta-Vietnam. The results show that our prediction is correct.

The research is a qualitative study conducted at ``Centro de Estudios Científicos y Tecnológicos``, Number 16 "Hidalgo", a high school belonging to the Instituto Politécnico Nacional. 16 "Hidalgo", a higher secondary school belonging to the National Polytechnic Institute; two years after having the face-to-face modality, there has been an increase in several mathematical errors implying a higher rate of failure or dropout; in the present return, the written evaluations (exams) were forced, with the analysis of the results of the new entrance groups of the school cycle 23-1 (August - December 2022) of the Algebra Learning Unit, showing a repetition of factors that affect the lack of previous knowledge of basic education (secondary level), besides that they come accustomed to bad study habits, copy and paste of concepts without the minimum interest in reading to know what they are talking about, plagiarism of activities and/or exercises, abuse of apps or web pages that solve tasks, disinterest, non-attendance, conformism, apathy, among others. These errors have become common among more students, a phenomenon that before the pandemic was not so visible and has aroused the concern of the teachers of the academy of Mathematics, since, of the ten and eight groups of new entrants, approximately forty students in each group, i.e. a population of 649 students was the sample of the analysis, with common results in errors such as: lack of mathematical spelling, correct application of properties, laws and mathematical axioms. These errors have become common among more students, a phenomenon that was not so visible before the pandemic and that has aroused the concern of the teachers of the Mathematics Academy, since, of the eighteen newly admitted groups, approximately Forty students from each group, that is, a population of 649 students, was the sample of the analysis, with common results in errors such as: the lack of mathematical spelling, correct application of mathematical properties, laws and axioms.

Solving mathematical word problems is a difficult, complex and intellectual activity. The formation of problem solving skills is much more difficult than calculation skills because the problems are related to many concepts and a lot of mathematical relationships. Therefore, students are inevitable to commit errors to deal with them. This study shows the errors of 160 3rd grade students regarding some kinds of word problems in Mathematics 3 in Vietnam. The results indicate that children commit many errors due to many different reasons such as: subjectivity, carelessness, wrong application of the calculation rules, incorrect identification of problem kinds and wrong calculation. Article visualizations:
With the continuous development of my country’s economy and society, the people’s requirements for education are getting higher and higher, and new curriculum standards have emerged as the times require, and mathematics education in primary school has also changed. To cultivate students' mathematical application ability, we need to implement the meaning and function of mathematical language to children to ensure that they can learn mathematical knowledge smoothly. Therefore, in our future work, we need to develop new skills It is an effective way to promote the continuous improvement of the teaching level of mathematics language.
