Mathematical Concept Understanding of Middle School Students: An Experimental Study of the Discovery Learning Model
Open accessAbstract
The role of conceptual understanding is essential because it enables students to more easily comprehend and learn mathematics. Therefore, this study focuses on the impact of the Discovery Learning model on the mathematical concept comprehension of students at a public middle school. The research employed an experimental method with a posttest-only control group design. The study's population included all eighth-grade students at public middle school 8 Gorontalo. The sample consisted of class VIII-5 as the experimental group, which implemented discovery learning, and class VIII-3 as the control group, which used a direct instruction learning model. Data was collected through an essay test administered as a post-test at the end of the study. Data analysis was performed descriptively and inferentially using a t-test. The results of the t-test indicated a t-calculated value of 3.506 and a t-table value of 1.6779, confirming that the t-calculated value is greater than the t-table value. Thus, it can be concluded that the Discovery Learning model has a significant influence on the mathematical concept comprehension of eighth-grade students at public middle school 8 in Gorontalo.

In the Discovery Learning model, teachers act as facilitators, guiding students to independently discover principles or concepts through experimentation and observation.
“In this model, teachers act as facilitators, guiding students to independently discover principles or concepts through experimentation and observation (Ananda & Atmojo, 2022;Maghfiroh et al., 2023;Ranggoli et al., 2025).”

The indexed study description (unpaginated) says the experimental group used Discovery Learning, but it does not describe teachers as facilitators or students discovering concepts through experimentation and observation. Searches for those roles and activities returned no passage addressing them. (LLM, conf=0.72)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
