Abstract
Abstract The aim of this study is to describe the formal thinking process of students in solving algebraic problems. This study is descriptive qualitative, with two 7 th grade subjects taken using a purposive sampling technique. The main instrument in this study is the researchers own judgment, Test of Logical Operations instruments, and algebraic problem-solving tests. The data were collected from various sources using the think-aloud approach. Data were analysed, classified based on students’ cognitive development types (concrete, transitional, and formal) and transcribed into data presentation. The study found that, at the stages of understanding the problem and implementing the plan to solve the problem, the subjects successfully carried out the process of thinking assimilation and abstraction. On the other hand, at the stages of planning and re-examining answers, the subjects able to perform the assimilation process of thinking.
