Pratiwi, Merina; Fitri, Dewi Yuliana; Cesaria, Anna – Mathematics Teaching Research Journal, 2022
This study induced the students to be more active and able to design discovery activities so that they can communicate the material's concepts well. Students can use their activities to find a solution to problems with inquiry-based learning materials that were supplemented with a guided note-taking model. For this reason, a valid, practical, and…
