Navigating EFL Classrooms: A Functional Analysis of Code-Mixing and Code-Switching as Instructional Strategies

Ayang Winda Sri Widianingsih — 2026-05-29

This research investigates the phenomenon of code-mixing and code-switching used by a teacher and fourth-semester students in an English as a Foreign Language (EFL) speaking class at a university in Bandung. The study is grounded in the fact that while learning a new language influences communication choices, excessive reliance on code-switching (CS) and code-mixing (CM) may hinder the mastery of English grammatical rules. This study aims to identify the specific types of CS and CM that occur during classroom interactions. Using a descriptive qualitative case study design, data were collected through online observations via Zoom meetings and audio recordings, which were then transcribed and analyzed using Poplack’s (1980) and Muysken’s (2004) frameworks. The results reveal that only specific types of linguistic shifts occurred: intra-sentential and inter-sentential switching were the primary forms of CS used by the teacher to ensure student understanding. Meanwhile, CM was manifested through insertion—such as adding Indonesian affixes to English base words—and alternation. The findings and discussion highlight that students frequently reverted to Indonesian or their mother tongue during group discussions due to vocabulary limitations and a lack of direct teacher monitoring. The study concludes that while these phenomena facilitate material comprehension, teachers should implement strategic rules to limit dependency on non-English codes to optimize students' speaking proficiency.

Hasti Pramesti Kusnara — 2026-05-29

This study investigates the integration of Digital Service Innovation in dividend policy and its impact on firm value, measured by Tobin's Q, with firm size as a mediating variable. Employing Signaling Theory and Agency Theory as the theoretical underpinnings, this research addresses the "Dividend Puzzle" within the context of the digital economy, where investors consider not only payout ratios but also a firm's capacity for digital innovation. Using a sample of 45 digital-sector and banking companies listed on the Indonesia Stock Exchange (IDX) from 2021 to 2025, the study employs Structural Equation Modeling with Partial Least Squares (SEM-PLS/SmartPLS) to simultaneously test mediation and moderation effects. The operationalization of variables includes the Dividend Payout Ratio (DPR) for dividend policy, the natural logarithm of total assets for firm size, and a digital innovation index derived from annual report disclosures. Results indicate that: (1) dividend policy exerts a significant positive effect on firm value; (2) firm size partially mediates the dividend-firm value relationship; and (3) Digital Service Innovation significantly moderates and strengthens the positive effect of dividend policy on Tobin's Q. These findings contribute empirical evidence to classical financial theory (M-M Theory and Bird-in-the-Hand Theory) by incorporating a technological dimension, and provide practical guidance for digital business managers in aligning dividend policies with digital innovation strategies.
