innovative and transformative, they are more motivated to adopt it meaningfully (Bonzanini
                  et al., 2020; Kottara et al., 2024). From the above arguments, the following hypothesis is
                  proposed:
                        H6: Perceived digital innovation positively affects teaching quality.
                        2.4. Research methodology
                        This study employed a quantitative research design to examine the factors influencing
                  the teaching quality of accounting lecturers in the context of digital transformation. The
                  target population consisted of accounting lecturers working at universities, colleges, and
                  other educational institutions offering accounting programs in Ho Chi Minh City. However,
                  due to the absence of a comprehensive sampling frame and practical constraints in
                  accessing respondents, a convenience sampling method was adopted through professional
                  networks and academic communication channels. While this approach is appropriate for
                  exploratory research, it may limit the generalizability of the findings. The questionnaire was
                  designed using Google Forms and distributed via email and other relevant communication
                  channels. A total of 159 valid responses were collected and used for the final analysis. This
                  sample size is considered adequate for PLS-SEM analysis and consistent with previous
                  studies in accounting education research.
                        The research model includes six independent variables: attitude toward technology,
                  technology experience, perceived digital innovation, perceived ease of use, perceived
                  usefulness, and institutional support. The dependent variable is teaching quality. Teaching
                  quality was measured using lecturers’ self-reported perceptions of their teaching
                  effectiveness in technology-enhanced environments. Although this approach is widely used
                  in behavioral research, potential self-report bias is acknowledged. Future studies are
                  recommended to incorporate multiple data sources, such as student evaluations or learning
                  outcomes, to improve measurement validity.
                        The measurement scales were developed based on the Technology Acceptance Model
                  (TAM) and the Theory of Planned Behavior (TPB), and adapted from prior studies related to
                  digital technology and accounting education, including Rodrigues (2022), Dangi et al. (2023),
                  Bonzanini et al. (2020), Hruska (2018), Fachrurrozie et al. (2025), Abdo-Salloum and Al-
                  Mousawi (2025), and Alshammari and Alkhwaldi (2025). All constructs were measured using
                  a five-point Likert scale ranging from 1 (strongly disagree) to 5 (strongly agree).
                        Data were analyzed using SmartPLS with Partial Least Squares Structural Equation
                  Modeling (PLS-SEM). This method was selected because the study aims to predict and
                  explore relationships among latent variables, and it is suitable for models with multiple
                  constructs and moderate sample sizes. The analysis procedure included descriptive statistics,
                  measurement model evaluation, and structural model assessment. The measurement model
                  was evaluated based on reliability, convergent validity, and discriminant validity, while the
                  structural model was assessed using path coefficients, coefficient of determination (R²),
                  effect size, and predictive relevance.
                        The sample size satisfies the commonly recommended ten-times rule for PLS-SEM.
                  Since the dependent variable is influenced by six structural paths, a minimum of 60
                  observations is required (Hair etal., 2019). With 159 valid responses, the sample size is
                  considered adequate for the analysis. Furthermore, the use of PLS-SEM is appropriate for
                  exploratory research in the context of accounting education in Vietnam, where empirical
                  studies on digital transformation remain limited.

                        3.1. Sample characteristics
                        Among the 159 respondents, 40.9% were male and 59.1% were female. The largest
                  age group was 30–40 years old, accounting for 49.1% of the sample, followed by
