Algebraic thinking is important for developing students' mathematical generalization abilities, and identifying patterns, shapes, and symbols. This study uses a qualitative descriptive approach that aims to describe the profile of students' algebraic thinking in solving modeling problems. The subjects of this study were 158 fifth-grade students in two private schools in Surakarta, Central Java. The data collection instrument used was six test questions related to the modeling component adopted from Ralston. Prior to use, the instrument was validated by 3 elementary school mathematics learning experts and tested on 10 students who were not the subject of the study. Based on the test results, there were 12 students who scored in the high category. This study focuses on analyzing the algebraic thinking profile of students with high categories. The results showed that high-category subjects were able to demonstrate understanding related to modeling indicators in algebraic thinking, namely understanding the meaning of the equal sign (=) as an equivalence relationship, using variables to solve problems in the form of equations, and understanding the relationships between arithmetic operations. However, a small number of subjects still experience calculation errors and understanding errors in algebraic operations. Hence, it can be concluded that subjects with high categories are able to demonstrate algebraic thinking skills in the modeling component

Algebraic thinking plays an essential role in increasing mathematics problem-solving abilities. In this study, the pre-service mathematics teacher’s (PMTs) ability of algebraic thinking is explored based on a systematic-intuitive cognitive style. This study aims to reveal students' algebraic thinking abilities regarding systematic-intuitive cognitive style. Three components of algebraic thinking were analyzed: arithmetic generalization, functional thinking, and generalization and justification. The research approach is qualitative with a case study method. The subjects were 31 PMTs at one of the private universities in Surakarta District, Central Java, Indonesia. Data collection methods were algebraic thinking tests, the Cognitive Style Inventory (CSI) questionnaires, and interview protocol. Four subjects, two PMTs for each cognitive style category were interviewed to reveal their algebraic thinking abilities. The results showed that all subjects were able to solve the functional thinking problem correctly. However, for the generalization arithmetics and justification problems, the PMTs abilities are varied. In addition, the finding also showed the different strategies of systematic and intuitive subjects in solving the problems related to algebraic thinking components. PMTs with a systematic cognitive style solve problems systematically and represent the pattern verbally in the form of a table or word, whereas the PMTs with an intuitive cognitive style solve the problem briefly and visually using pictures pattern. In conclusion, there is a relationship between algebraic thinking ability and cognitive style.

The algebraic thinking is very important for students to be able to abstract and generalize a mathematical problem. The purpose of this research is to reveal students' algebraic thinking processes in solving math problems based on reflective-impulsive cognitive styles. The method used is a qualitative with a case study approach. The research subjects consisted of 55 students who were then selected six students based on the reflective-impulsive cognitive style. The research instrument used consisted of an algebraic thinking test that adopted from TIMSS (Trends in International Mathematics and Science Study), MFFT (Matching Familiar Figure Test) and an interview guide. In this paper, researchers are focus on the exploration of students' algebraic thinking ability in solving problems on generalization and abstraction components. The finding showed that the reflective subjects and impulsive subjects are able to solve generalization and abstraction problems. The reflective and impulsive subjects are able to use patterns to solve problems related to generalizations. In addition, reflective and impulsive subjects are able to use symbols as an abstraction of the relationship between concepts and mathematical properties. However, the reflective subjects used the solution problem steps more systematic than impulsive subjects. The implication of the finding is that the individual differences such as cognitive style should be facilitated by the teachers so that students are more successful in learning mathematics.

In the era of independent learning, there was a low interest in and understanding of Natural Sciences (IPA) subjects among students. The project-based learning model emerged as an alternative to overcoming these constraints. So researchers want to know the impact of project-based learning in primary schools. The method used is pre-experimental quantitative, with the design as follows: taking samples, pretest, providing guidance, post-test after guidance, looking for the average value of the pretest and post-test, and T test results. The research was conducted at Surakarta Basic School with a 30th grade student. Types of bound variables are the values and understanding of students in the V class of Natural Sciences (IPA) and project-based free learning variables. Collecting techniques with post-test and post-test as well as data analysis with pairs of T tests. Research finds that project-based learning models have an influence on elementary school students in the fifth grade in natural science subjects (IPA). Based on the analysis, results show that t hitung > t table (2.977 > 1.6991) means there are significant differences, so the project-based learning model has an influence on value and understanding.
