“…Therefore, this research aims to determine the effect of worksheets on students' critical and creative mathematical thinking abilities on linear equations in one variable. Although previous researchers have carried out worksheets on equations and inequalities of one variable, such as worksheets based on Realistic Mathematics Education (Gustin et al, 2020), worksheets based on brain learning (Pramagda & Sari, 2021), worksheet-based problems with wetland environmental context (Azizah et al, 2023), and worksheet based scientific approach (Halimah et al, 2023), but worksheets on the same material as the Tri-N approach have not been carried out by many researchers so far. Hence, this includes added value and differences with previous research.…”
