Retraction: Factors Affecting the Effectiveness of English-Medium Instruction Program in Mathematics Education: An EFA–CFA Study

This article has been retracted by the editorial board of TEFLIN Journal.

After publication, concerns were raised regarding the accuracy and verifiability of several references cited in the article. The journal conducted an editorial assessment and contacted the authors for clarification. During this process, some cited sources in the published version could not be independently verified, and replacement references later provided differed from those originally cited. Consequently, the editorial board was unable to confirm that the cited literature supports the claims presented in the paper.

Because these issues affect the reliability of the work and cannot be resolved through correction of the version of record, the article has been retracted to preserve the integrity of the scholarly record.

This notice addresses the reliability of the publication and does not represent a determination of the authors’ intent. The article will remain available online with a clear retraction watermark indicating its retracted status.
