EXPLORATION OF LEARNING OBSTACLE BASED ON MATHEMATICAL UNDERSTANDING OF ALGEBRA IN JUNIOR HIGH SCHOOL. The difficulty of students related to algebra arises from the lack of students' mathematical understanding and Learning Obstacle (LO). One of the LO's experienced by students is the epistemological obstacle in the form of the limited knowledge possessed by students in mathematical concepts related to algebraic form. The purpose of this study is to explore LO related to algebra material. This research method is qualitative with the consisted of 15 students of 7th grade. The results showed that the common students could not interpret concepts and clarify the elements of algebraic forms related to variables, coefficients and constants and students could not operate and simply algebraic forms. The teacher can make pedagogical and didactic anticipations to overcome the LO.
Difficulties that Students Face when Learning Algebraic Problem-Solving
Universal Journal of Educational Research, 2020
Algebraic problem-solving is a way of thinking and reasoning that allows students to create models, study relationships, and solve problems. However, students only have a little understanding of formulating and solving algebraic problems. This study aims to determine the predominant difficulties that Year Six students face when learning algebraic problem-solving. This study used a quantitative research design involving 80 students selected by purposive sampling. The instruments used in this study include criterion-referenced tests consisting of word and diagram algebraic problem-solving items. Data were analysed using GNU PSPP software. The descriptive statistics showed that the predominant difficulty that Year Six students faced when solving algebraic word problems was text difficulties and unfamiliar contexts. For diagrammatic algebraic problem-solving, students encountered the most difficulty with visual-spatial awareness. The Chi-Square test was used to identify the statistical correlation coefficient between gender and difficulties in solving algebraic problems. The result showed a positive association between gender and recognition difficulties and gender and sign substitution error. The findings of this study may encourage students to better learn algebraic problem-solving skills. Moreover, this study also provides important information for teachers to better teach algebraic problem-solving to Year Six students.
Algebraic Thinking Profiles of Junior High Schools’ Pupil in Mathematics Problem Solving
International Journal of Trends in Mathematics Education Research
Algebra is one of concept that must be learned by pupils. It is because the algebraic concept can be used in all areas of mathematics. One of the ways that is used to develop pupils' algebraic abilities is to think algebraically. While one of the ways to develop pupils' algebraic thinking skills is to adapt pupils with mathematical problem solving. The purpose of this study is describing algebraic thinking profiles of junior high school pupils in mathematical problem solving. The description of pupils' algebraic thinking profiles is explained based on six indicators namely generalization, abstraction, analytic thinking, dynamic thinking, modeling and organization. This research is a qualitative study using test and interview methods.

The results showed that there were differences in algebraic thinking of junior ...
The study was conducted on selected students of the University of Southern Mindanao from July to August 2013 and included 34 respondents. The main objective of the study was to identify the challenges encountered by students in solving Algebra word problems. Descriptive method was used. A prepared assessment tool was administered to the respondents who were conveniently chosen. Data were analyzed using mean frequency and percentage. Result of the study shows that the students encountered challenges were difficulty in translating the word problems in mathematical phrase. With this dilemma, students usually opted to give up than find ways to answer the problem. Students look for numerical values in the problem and apply any of the fundamental operations where they think would work. This can be call Guess and Check method but students usually misused it because they disregard the conditions given in the problem. Students cannot combine learned rules and principles into mixed or combination of using those rules and principles. Students lack the skills needed to solve word problems such as understanding the language of algebra; concepts of LCM, decimals, percentage; and simplifying algebraic expressions. Based on the results of this study the researcher conclude that failure to solve algebraic word problems is due to lack of prerequisite skills, haven’t understand the concepts of rules and principles in algebra , that’s why they cannot apply their learned rules and principles into complex conditions that needs combinations of those rules and principles. Students memorize the process of their teacher in solving the problems that’s why when they encounter parallel problems they cram and blame the teacher because for not teaching about it. They don’t understand the concept deeply so they say their teacher hasn’t taught it where in fact it’s a parallel problem. To sum up the findings, challenges encountered by the students were difficulty in translating the word problems to mathematical phrase because they have not learned the language of algebra and in simplifying algebraic equation.

STUDENTS' DIFFICULTIES IN SOLVING MATHEMATICAL PROBLEMS
The purpose of this study is to analyze the ability and students' difficulties in solving mathematical problems. This study is a qualitative research with the number of participants-32 students consisting of 16 male students and 16 female students with an age range of 12-13 years. Data were collected by observation, interviews, and tests of social arithmetic problems. The results showed that junior high school students have low ability in solving mathematical problems. The low ability of students' mathematical problem solving is caused by several factors, namely (1) students can not understand the keyword of social arithmetic problem; (2) students can not develop problem solving strategy based on problem in question; (3) students easily give up in the face of every difficulty and error; (4) students do not like to read long and unclear questions in reading questions; (5) students are not careful in the calculation process; (6) the student is wrong in taking and determining the concept or strategy of completion; and (7) the students did not verify either in terms of concepts, strategies, calculations, and answers. In subsequent research, our objective is to focus more on student activities in solving mathematical problems.
