This case study investigated the implementation of the delayed scaffolding strategy by the teacher using GeoGebra software in learning the topic of absolute functions. This strategy aimed to assist the vocational students to understand the representation of the expression of absolute function symbols in graphical form. The results of the study show that the implementation of delayed scaffolding using GeoGebra improved students’ ability to draw conclusions in understanding the representation of absolute functions in graphical form. This strategy has positive effects on students in the process of learning mathematics, especially for vocational students in Indonesia.


Keywords – Delayed scaffolding, GeoGebra, vocational students, draw conclusions, absolute functions.
