Abstract

This study investigates mathematical abstraction, answer methodology, and student application of derivatives. qualitative investigation. Children in class XI SMA PRIVATE AN - NIZAM Medan were exposed to science and PBL. This study investigates the PBL mathematical abstraction model. This study comprises student response sheets from a mathematical abstraction exam, subject interviews, and field notes. 4 students had a ^high^ level (21%), 11 students had a ^medium^ level (58%), and 5 students had a ^low^ level (5%). Students utilized GeoGebra Software to reformulate concepts, formulate the problem mathematically, and solve it. 19 students properly explained the question 1 dilemma. 17 (89.5%) students comprehended questions 2. Two students (10.5%) were unable to be recognized. 12 students (63.2%) explained question 3^s difficulty. 7 students (36.8%) failed the recognition test. 8 students (42. 1%) explained question 4^s difficulty. 11 students (58.9%) failed the recognition test. 18 pupils responded to question 1. Students can compose and demonstrate these concepts. 14 students mathematically modeled the second question. Also, students can overcome problems. Ten students responded to Question 3^s representation level, while only eight responded to Question 4. 15 students utilized derived concepts and principles to complete the structural abstraction for issue 1. Twelve students responded to question 2. 8 students employed structural abstraction principles to question 3 and 6 to question 4. Geogebra Software and Problem-Based Learning evaluate abstract mathematics: Abstract mathematical theorems Students are able to paraphrase, model, and solve problems. Mathematically abstract children are unable to complete puzzles on time. Students are unable to describe problem solving. An integer. Mathematicians summarize in a way that is moderately abstract. The difficulty of concept linking, mathematical modeling, and problem solving increased. Previous math topics may present difficulties for students. Geogebra problems enhance understanding. If children neglect math, problem-based learning and Geogebra will be ineffective. Students with a low level of mathematical abstraction cannot articulate concepts, model queries, or answer problems.
