#### 3.1.2 Exploratory Factor Analysis of Teaching Practice
These three items have high factor loadings, especially PD1 and PD2, which exceed 0.90, indicating that they are very strongly related to the factor. This factor may represent a clear and definite construct to which the items are strongly associated. PD3, although it has a lower loading (0.599), is still well-aligned with this factor, contributing to the same latent construct. Factor 2 \"Media\" is composed of items PD5 (0.901) and PD6 (0.838). This factor has two items with high factor loadings, indicating that both items are strongly aligned with the factor. Loadings above 0.80 suggest that these items measure the underlying construct represented by this factor very well. Given the high magnitude of the factor loadings, this factor is very well-defined by items PD5 and PD6. Factor 3 \"Student collaboration\" is composed of the items PD8 (0.589), PD9 (0.679), PD10 (0.731), and PD11 (0.595). The items associated with this factor also present high factor loadings, particularly PD10 (0.731) and PD9 (0.679), indicating that these items are strongly related to the construct represented by this factor. All items in this factor exceed a loading of 0.50, suggesting that they are adequately represented by this factor. Factor 4 \"Teaching process\" is composed of the items PD17 (0.589), PD19 (0.558), PD20 (0.722), PD21 (0.813), PD22 (0.640), PD26 (0.554), PD27 (0.625), PD28 (0.623), and PD32 (0.525). This factor has a greater number of associated items, all with factor loadings exceeding 0.50, indicating a good association with the factor. PD21 stands out with a loading of 0.813, suggesting a strong alignment with this construct. Other items such as PD20 and PD22 also have a strong relationship with the factor, indicating that this factor is well-defined and represents a clear construct. Factor 5 \"Teacher support\" is composed of the items PD33 (0.810), PD34 (0.780), and PD35 (0.513). This factor also has items with high factor loadings, especially PD33 (0.810) and PD34 (0.780), indicating a strong association with the underlying construct. PD35, although it has a lower loading (0.513), is still adequately represented in this factor. Beyond those, item PD18 was eliminated for not containing factor loadings greater than 0.30, item PD4 was eliminated for having a variance ratio of 1.07, item PD12 was eliminated for having a variance ratio of 1.08, item PD23 was eliminated for having a variance ratio of 1.43, item PD29 was eliminated for having a variance ratio of 1.23, item PD25 was eliminated for having a commonality of 0.352, item PD7 was eliminated for having a commonality of 0.363, item PD24 was eliminated for having a commonality of 0.376, item PD31 was eliminated for having a variance ratio of 1.39, item PD30 was eliminated for having a variance ratio of 1.05, item PD14 was eliminated for having a commonality of 0.381, item PD15 was eliminated for having a commonality of 0.379, item PD13 was eliminated for having a commonality of 0.378, and item PD16 was eliminated for having a commonality of 0.391. In total, 14 items were eliminated. The final results of the exploratory factor analysis for teaching practice show that the Kaiser-Meyer-Olkin measure (KMO) of sampling adequacy is 0.920, which indicates that the data are adequate to perform a factor analysis since a value greater than 0.9 is excellent. [PERSON]'s test of sphericity is highly significant (\(p<0.001\)), with an approximate chi-square value of 12,841.328 and 210 degrees of freedom (gl). These results suggest that the correlations between the items are not identifiable, so it is appropriate to perform a factor analysis. Table 5 shows the final commonalities of the items in the exploratory factor analysis of teaching practice. Higher values, as in items PD1 (0.806), PD2 (0.808), and PD5 (0.802), indicate that these items have a stronger relationship with the underlying factors and are better explained by them.
