The monotonicity of a function plays an important role in the general mathematics curriculum in Vietnam, because it is considered as an effective tool for solving mathematical problems involved with the monotonic intervals of functions, their extreme, absolute maximum value and absolute minimum value. Normally, students commit errors in solving these problems because of their complexity and difficulty. In addition, specific characteristics of knowledge also make children make mistakes. The sample consisted of 362 students, and they had the task of identifying errors in false assumptions. From the results of the survey, it was found that when dealing with the monotonicity of the functions, students were still misled.

Exploring Students" Image Concepts Of Mathematical Functions Through Error AnalysisStudents do not necessarily use the definitions presented to them when determining examples or non-examples of given mathematical ideas. Instead, they utilize the concept image they carry with them as a result of experiences with such examples and non-examples. Hence, teachers should try exploring students" images of various mathematical concepts in order to improve communication between students and teachers. This suggestion can be addressed through error analysis. This study therefore is a descriptive-qualitative type that looked into the errors committed by senior high school students in dealing with mathematical functions, explored the underlying reasons for such errors, and provided recommendations on how students could learn to manage their errors and how teachers could realize how to manage students" errors. Initial findings showed that the students generally demonstrated mathematical, logical and strategic errors. Mathematical error was generally exhibited in their inability to use properties and operations properly. Logical error was exhibited in their false arguments, rearranging concepts, improper classifications, arguing cyclically, and using equivalent transforms. Strategic error was manifested in their not being able to distinguish patterns, lack of integral concept, and not being able to transform a word problem into symbols. Errors prevailed despite the students" positive view and confidence in mathematics not only because of poor image concepts but because of lack of exposure to certain important mathematical tasks. Further investigation on the other sources of these errors is therefore necessary.

Identification of Mathematical Errors Committed by Senior School Students in CalculusThis study aimed to identify mathematical errors committed by senior school students in calculus. Specifically, this study analyzes the various types of errors committed when solving problems involving calculus. The study is a descriptive study that employed a mathematics performance test on calculus (MPT-C) as the research instrument. The study considered two independent variables which are: error type and gender. The research sample for the study comprised all senior secondary school three (SS III) students. A random sampling technique was used to select the participating schools. A total of 300 senior secondary school students were involved in the selected schools. All research questions were answered using mean gain difference while all research hypotheses were tested using chi-square. All the research hypotheses were tested at a 0.05-significance level. The results of the analysis indicated that: there were no significant differences in the frequencies of structural, suppositio...

A case study of misconceptions students in the learning of mathematics; The concept limit function in high school2017 •
This study aims to find out how high the level and trends of student misconceptions experienced by high school students in Indonesia. The subject of research that is a class XI student of Natural Science (IPA) SMA Negeri 1 Anjatan with the subject matter limit function. Forms of research used in this study is a qualitative research, with a strategy that is descriptive qualitative research. The data analysis focused on the results of the students' answers on the test essay subject matter limit function with the number of students by 16 (sixteen). Data collection techniques used are shaped test methods essay, interview method to students who have misconceptions, and methods of documentation of the test answers. Examination of the validity of the data using a triangulation technique that compares the data written test results with data from interviews. The results of this study can be described as follows; (1) The level of misconceptions experienced by students belonging to the category of low, amounting to 12.18%. However, students who do not understand the concept quite high at 40.38%, and the others are students who understand the concept that is equal to 47.44%. (2) The misconception most experienced students lie in subconcepts explain the meaning of limit function at one point through the calculation of values around that point, that is equal to 20.51%. The tendency misconceptions experienced by students is located on errors and operating concepts that misconceptions students that there should be no limit in the completion of the writing of the emblem and misconceptions about the limit students to conclude if the limit value of 0 is no limit to the value of the function.

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
In this paper some common mistakes are investigated, referred to linear mappings and to the solution of algebraic equations, with reference to High School students (students aged 16-19 years). We conclude that pupils sometimes improperly extend «simple» rules, and this is caused by algebraic weakness and by affective elements, too. As regards strategies against misguided generalisations, we underline that the effect of counterexamples with pupils is frequently weak, since often they are not able to interpret counterexamples in an adequate way.
