The table reports the number of questionnaire items, mean (M), standard deviation (SD), minimum observed value, and maximum observed value for teaching style, ChatGPT usage, digital literacy, motivation, foreign language classroom anxiety, and creativity based on responses from 280 participants.
Common Method Variance Bias
Common method variance (CMV) bias refers to spurious covariance among variables attributable to the measurement method rather than the constructs being measured. Because this study used a self-reported survey, both procedural and statistical approaches were employed to assess the potential influence of CMV bias. Procedurally, participants were assured of anonymity and confidentiality to minimize social desirability bias and encourage honest responses. In addition, questionnaire items adapted from established instruments were presented in a randomized order to reduce response patterns that could artificially inflate CMV bias. Statistically, Harman’s single-factor test was conducted by entering all measured variables into an exploratory factor analysis (EFA) without rotation. The analysis showed that the first unrotated factor explained 32.7% of the total variance, which is below the recommended threshold of 50%, indicating that CMV bias was unlikely to substantially influence the study findings (Table 3).
| Statistic | Value | Threshold | Interpretation |
| Total number of factors extracted | 7 | N/A | Multiple factors were extracted, indicating that the measured items represent distinct constructs. |
| Variance explained by the first factor | 32.70% | <50% | Below the commonly accepted threshold, indicating that common method variance (CMV) is unlikely to be a serious concern. |
| Cumulative variance explained (first three factors) | 62.10% | N/A | Indicates that the first three factors account for a substantial proportion of the total variance. |
| Kaiser–Meyer–Olkin (KMO) measure of sampling adequacy | 0.89 | >0.80 | Indicates excellent sampling adequacy for factor analysis. |
| Bartlett's test of sphericity (p value) | <0.001 | p < 0.05 | Significant result indicating that the correlation matrix is suitable for factor analysis. |
Table 3: Harman’s single-factor test and sampling adequacy results. The table summarizes the results of Harman’s single-factor test, the Kaiser–Meyer–Olkin (KMO) measure of sampling adequacy, and Bartlett’s test of sphericity. Harman’s single-factor test was performed to assess the potential influence of common method variance (CMV). The KMO statistic and Bartlett’s test were used to evaluate the suitability of the dataset for factor analysis.
Table 3 presents the results of Harman’s single-factor test, indicating that the first unrotated factor accounted for 32.7% of the total variance, which is below the recommended 50% threshold and suggests that common method bias is not a substantial concern in this study. The Kaiser–Meyer–Olkin (KMO) measure of sampling adequacy was 0.89, indicating that the data were suitable for factor analysis. In addition, Bartlett’s test of sphericity was statistically significant (p < 0.001), confirming that the correlation matrix was appropriate for factor analysis. Collectively, these findings support the suitability of the dataset for subsequent structural equation modeling analyses.
Measurement Model
The measurement model was evaluated to assess the reliability and validity of the study constructs using PLS-SEM implemented in SmartPLS 4, following the recommendations of Hair et al.60 Indicator reliability, internal consistency reliability, convergent validity, and discriminant validity were assessed. Indicator reliability was evaluated using outer loadings, with items exhibiting loadings greater than 0.70 retained as reliable indicators of their respective constructs. Items with loadings between 0.60 and 0.70 were retained only when their removal did not improve the internal consistency of the corresponding construct. Internal consistency reliability was assessed using Cronbach’s alpha and CR. Convergent validity was evaluated using the AVE, with all constructs demonstrating AVE values greater than 0.50, indicating that each construct explained more than half of the variance in its indicators. Discriminant validity was assessed using the HTMT ratio, and all HTMT values were below the recommended threshold of 0.85, supporting the empirical distinctiveness of the study constructs (Tables 4 and 5).

Results of Hypothesis Testing (Structural Model)
The structural model was evaluated to examine the hypothesized relationships among teaching style, ChatGPT usage, digital literacy, motivation, FLCA, and creativity. The results supported all proposed direct and mediation hypotheses. Teaching style, ChatGPT usage, and digital literacy were positively associated with motivation. Motivation was negatively associated with FLCA, whereas FLCA was negatively associated with creativity. In addition, motivation mediated the relationships between teaching style, ChatGPT usage, and digital literacy and FLCA (Tables 6 and 7).

Table 7: Mediation analysis. The table summarizes the indirect effects estimated using partial least squares structural equation modeling (PLS-SEM). Reported statistics include the standardized indirect effect (β), t value, p value, 95% bootstrap confidence interval (CI), lower limit of the confidence interval (LLCI), upper limit of the confidence interval (ULCI), and the decision regarding hypothesis support. Statistical significance was evaluated using bootstrapping with 5,000 resamples.
Table 6 presents the results of the direct-effect analyses. All five hypothesized direct relationships were statistically significant (p < 0.001), supporting hypotheses H1–H5. Teaching style (β = 0.36), ChatGPT usage (β = 0.40), and digital literacy (β = 0.33) were positively associated with EFL students’ motivation, with ChatGPT usage demonstrating the largest standardized path coefficient among the three predictors. Motivation was negatively associated with FLCA (β = –0.27), indicating that higher motivation corresponded to lower levels of anxiety. In turn, FLCA was negatively associated with creativity (β = –0.26). The 95% bootstrap confidence intervals for all direct effects excluded zero, supporting the statistical significance of the hypothesized relationships. Table 7 presents the mediation analyses examining whether motivation mediated the relationships between teaching style, ChatGPT usage, and digital literacy and FLCA. The indirect effects were statistically significant for all three pathways (H6: β = 0.28, t = 4.56, p < 0.001; H7: β = 0.34, t = 5.02, p < 0.001; H8: β = 0.30, t = 4.68, p < 0.001). The 95% bootstrap confidence intervals excluded zero for all indirect effects, supporting the statistical significance of the mediation pathways. The positive indirect coefficients reflect the overall magnitude of the indirect effects through motivation, whereas the direct relationship between motivation and FLCA was negative, as reported in the structural model. Consequently, higher levels of teaching style, ChatGPT usage, and digital literacy were associated with higher motivation, which, in turn, was associated with lower FLCA (Tables 6 and 7). Overall, the structural model supported all hypothesized direct (H1–H5) and indirect (H6–H8) relationships. The findings indicate statistically significant associations among teaching style, ChatGPT usage, digital literacy, motivation, FLCA, and creativity, with motivation acting as the significant mediator evaluated in the structural model.
Dimensional Analysis of Teaching Style
A dimensional analysis was conducted to examine the relationships between the five teaching style dimensions and EFL students’ motivation, FLCA, and creativity. The teaching style dimensions included Authority, Expert, Personal Model, Facilitator, and Delegator. The structural model estimated the direct effects of each teaching style dimension on the three outcome variables to determine whether the observed relationships differed across teaching approaches (Table 8).

Table 8: Dimensional analysis of teaching style. The table reports the direct relationships between the Authority, Expert, Personal Model, Facilitator, and Delegator teaching style dimensions and the outcome variables of motivation, foreign language classroom anxiety, and creativity. Reported statistics include the standardized path coefficient (β), t value, p value, lower limit of the 95% bootstrap confidence interval (LLCI), upper limit of the 95% bootstrap confidence interval (ULCI), and the decision regarding hypothesis support.
Table 8 presents the results of the dimensional analysis of teaching styles. The Facilitator teaching style demonstrated the strongest positive associations with motivation (β = 0.34, p < 0.001) and creativity (β = 0.31, p < 0.001), together with the strongest negative association with FLCA (β = –0.28, p < 0.001). The Expert, Personal Model, and Delegator teaching styles were also positively associated with motivation (β = 0.30, 0.25, and 0.29, respectively) and creativity (β = 0.22, 0.24, and 0.27, respectively), while showing negative associations with FLCA (β = –0.18, –0.22, and –0.24, respectively). All of these relationships were statistically significant. In contrast, the Authority teaching style was not significantly associated with motivation (β = 0.12, p = 0.065). However, it showed a significant positive association with FLCA (β = 0.35, p < 0.001) and a significant negative association with creativity (β = –0.28, p < 0.001). Overall, the dimensional analysis demonstrates distinct patterns of association between individual teaching style dimensions and the measured learning outcomes. Taken together, the dimensional analysis indicates that the associations between teaching style and student outcomes vary across teaching style dimensions. Statistically significant relationships were observed for most teaching style dimensions, whereas the Authority teaching style did not demonstrate a statistically significant association with motivation.
Predictive Validity of the Inner Model Using PLS Predict
The predictive validity of the structural model was evaluated using the PLS Predict procedure to assess the model’s out-of-sample predictive performance. Predictive relevance was evaluated using the Q2 Predict statistic together with prediction error measures, including the root mean square error (RMSE) and the mean absolute error (MAE). The Q2 Predict values ranged from 0.32 to 0.48 across the endogenous constructs, indicating positive predictive relevance. Motivation and creativity demonstrated the highest Q2 Predict values (0.42 and 0.48, respectively). Prediction error values were also examined, with RMSE ranging from 0.54 to 0.63 and MAE ranging from 0.41 to 0.49 across the endogenous constructs (Table 9).
| Construct | Coefficient of Determination
(R²) | Predictive Relevance
(Q² Predict) | Root Mean Square Error
(RMSE) | Mean Absolute Error
(MAE) |
| Motivation | 0.45 | 0.42 | 0.61 | 0.48 |
| Foreign Language Classroom Anxiety | 0.38 | 0.32 | 0.63 | 0.49 |
| Creativity | 0.42 | 0.48 | 0.54 | 0.41 |
Table 9: Predictive performance of the structural model. The table summarizes the predictive performance of the endogenous constructs evaluated using partial least squares structural equation modeling (PLS-SEM). Reported statistics include the coefficient of determination (R2), predictive relevance (Q2 Predict), root mean square error (RMSE), and mean absolute error (MAE). Higher R2 and Q2 Predict values indicate greater explanatory and predictive performance, whereas lower RMSE and MAE values indicate lower prediction error.
Table 9 summarizes the predictive performance of the structural model. The coefficient of determination (R2) indicated that the model explained 45% of the variance in motivation, 38% of the variance in FLCA, and 42% of the variance in creativity. The Q2 Predict values for motivation (0.42), FLCA (0.32), and creativity (0.48) were all greater than zero, supporting the predictive relevance of the model. The RMSE values ranged from 0.54 to 0.63, whereas the MAE values ranged from 0.41 to 0.49, indicating the prediction errors for the endogenous constructs. Overall, the predictive performance measures support the predictive capability of the structural model.
Figure 4 illustrates the predictive performance of the endogenous constructs by presenting the coefficient of determination (R2), predictive relevance (Q2 Predict), and prediction error measures (RMSE and MAE). Among the endogenous constructs, creativity showed the highest Q2 Predict value (0.48) together with the lowest prediction errors (RMSE = 0.54; MAE = 0.41), whereas motivation demonstrated the highest explained variance (R2 = 0.45) (Figure 4). Overall, the PLS Predict analysis demonstrated positive predictive relevance for all endogenous constructs. The R2, Q2 Predict, RMSE, and MAE results collectively support the predictive performance of the structural model for motivation, FLCA, and creativity (Table 9; Figure 4).

Figure 4. Predictive performance of the structural model. The graph presents the coefficient of determination (R2), root mean square error (RMSE), mean absolute error (MAE), and Q2 predict values for the endogenous constructs of motivation, anxiety, and creativity. Bars represent R2, RMSE, and MAE values, and the line with circular markers represents Q2 predict values. Higher R2 and Q2 predict values indicate greater explanatory and predictive performance, respectively, whereas lower RMSE and MAE values indicate lower prediction error.
