There have been several discussions on the educational evaluation methods, and various studies dealing the issue have been reported. In addition, there are several activities for enhancing the evaluation’s professionalism such as features of reliability, validity as well as the equity.
Among the evaluation methods, the Rubric is the evaluation method describing the evaluation standards. For the cosmetic subjects, the practical performance should be tested as well as the written test, so there are more difficulties in accurately and fairly evaluating the practice performance test than the existing written tests.
This study investigated the Rubric’s influence on the academic performance in the educational evaluation for cosmetic subjects. This study selected the units applying the Rubric method as the unit of ‘Skin-Care (2011)’, the national textbook for cosmetic high school, and the two units of ‘Cleansing Procedure and ‘Facial Mask and Finishing Care’(2012), which are the two subjects among common 7 subjects to be tested in the national beauty expert(skin care) certificate exam.
After developing the draft of Rubric, the 3 professors in the department of cosmetic education, and the content validity of was conducted by 3 teachers teaching the cosmetic subjects. And then the final Rubric model was developed, To verify the appropriateness of final Rubric model, the investigator conducted the survey asking ‘the instrument understanding’, ‘the instrument validity’, ‘the instrument reliability’, ‘the utilization easiness’, ‘the teacher’s preparedness ’ and ‘the result utilization’ targeting 30 teachers.
Also, in order to find out the Rubric’ influence on the academic performance at applying the test, the investigator divided some students in the 2nd-grade of high school in to the experiment group and the control group, and then conducted the pre-test and the post-test be fore and after the academic performancee valuation. Additionally, the investigator conducted the survey asking the Rubric’s influence on the results of educational evaluation targeting the experiment group who were tested by the Rubric model.
The findings of this study are as follows:
First, the results from the Rubric’s appropriateness evaluation are as follows. In the survey targeting the teachers asking the appropriateness of Rubric model, it was shown that the factors of ‘instrument reliability’ and ‘result utilization’ had the highest scores. The highest scores of ‘instrument reliability’ means that if the Rubric model would applied to evaluate the academic performance, the same student would have the same score despite being calculated by different scorers. The highest score of ‘result utilization’ means that the scores resulting from the application of the Rubric model could provide useful feedbacks to both the students and the teachers.
Next, the higher scores followed ‘the instrument validity’, ‘the instrument understanding’, and ‘the utilization easiness’ in order.
Meanwhile, the ‘teacher’s preparedness’ had the lowest score. The reason is considered as because the teachers felt some difficulties in applying the Rubric model without any additional training. So, it is considered as that any training for additional training relevant the Rubric model would be need in order to enhance the easiness of teacher’s utilization for the Rubric model.
Second, at applying the Rubric model, its influence on the academic performance produced following results.
In the pre-test before conducting the academic performance test, the both groups (experiment and control groups) did not show any difference in their scores (p>0.05).
For the control group, the results between the pre-test and the post-test (the unit of cleansing procedure) showed some significant enhancement in evaluation items of ‘cleansing-motion explanatory diagram’, ‘work attitude’ in the practice process and ‘practice attitude’ in the practice attitude The reason of significant differences is considered as because the twice classes provided for the pre-test and the post-test might partly enhance the students’ performance.
For the experiment group, the results between the pre-test and the post-test (the unit of cleansing procedure) showed some significant enhancement in all evaluation items of ‘cleansing-motion explanatory diagram’, ‘work attitude’ and ‘point cleansing-motion’, ‘tool using method’, ‘cleansing-motion technique’ in the practice plan, and ‘work outcome’ , ‘harmony’ in the practice outcome, the ‘practice attitude’ in the practice attitude. The reason attitude of significant differences is considered as because the provision of careful guidelines about the Rubric model might enhance the students’ academic performance.
True purpose of education evaluation is in improving educational activities, not in collecting, analyzing and reporting the data about the evaluation targets. Like that, it needs to help students to increase their academic performance by applying the Rubric model, not simply evaluating the students.
In addition, in the educational evaluation using the Rubric model, the students showed much positive result in the ‘instrument reliability’. That means that even though different scorers calculate the same item for a student, the score would be same. Besides, as the all other parts of Rubric model got positive results, so the Rubric model will be good in being expanded into other cosmetic subjects.
Based on the results of this study, it is expected for objective Rubric models to be developed in other cosmetic subjects.
