Competency for training teacher to conduct the role has been emphasized to achieve the purpose and meaning of vocational training, and successful operation. To provide high-quality vocational training service, it needs to develop scale to be able to measure competency level of vocational training teacher methodically and systematically based on competency model. Although there is existing study on development of competency model to utilize it on vocational training field, the study up to scale development is not enough. According to this need, the study attempted to develop scale development of vocational training teacher and find the building blocks which are required for training teachers. The study attempted to develop a credible and reliable scale development of training teacher suitable for vocational straining field based on the training teacher competency model.
Three study questions were followed to achieve the purpose above. First, “How could a vocational competency development training teacher competency model be developed?” Second, “How could training teacher competencies be measured – in what way and by what criteria?” Third, “How could a training teacher competency scale be proven reliable and credible?” To solve these questions above, a scale of training teacher competencies were developed using three steps: definition of measurement concept and construction, selection of competency item pool & verification, and scale verification.
In the first step, a training teacher competency model was outlined by construction of draft competency model through preceding research analysis, verification of draft competency model through a focus group meeting of vocational training field experts, behavioral event interviews of field training teachers. Education experts reviewed the resulting competency model.
In the second step, to select and verify competency item pool, a competency item pool was developed by a focus group meeting of vocational training managers and field experts respectively. This was validated by education experts and further verified through a survey of 58 vocational training teachers. In the third step of scale verification, 620 field training teachers were surveyed using the verified item pool. Cross validity and reliability were verified by dividing the samples between group A and group B. Exploratory factor analysis was computed for group A and confirmatory factor analysis was computed for group B to finalize the scale.
The results of this study are as follows. First, the study expanded the range of subjects from restricted to qualified vocational training teacher on existing study to unqualified training teacher to develop training teacher competency model and scale. This training teacher competency model is developed reflecting hierarchy and multidimensional characteristic generally usable in vocational training field.
Second, competency model creation is followed by development of a validated competency scale. This training teacher competency scale is able to diagnose and evaluate area and blocks required to measure. This competency scale is consistent to extract and interpret the result of measurement, and also verified reliability by reproducability. Third, the training teacher competency model and scale could be utilized for selection, training, development, evaluation, succession plan to manage and develop human resource, and developing the foundation of workplace learning to manage human resource and enforce competency.
Empirical study should continue by training teacher scale 7 competency groups, 18 competencies, 75 item pools finally built by suggestion for follow-up research. It is expected for this scale to be utilized for the selection of training teacher, training and development, reward and coaching through evaluation, succession plan throughout the training center after applying the study results to further samples. It is also expected to be utilized for objective evaluation index of training center and training course throughout the nation.
