実務実習事前教育に向けたテキストマイニング手法の活用

抄録

  We developed a new survey analysis technique to understand students' actual aims for effective pretraining prior to clinical practice. We asked third-year undergraduate students to write fixed-style complete and free sentences on “preparation of drug dispensing.” Then, we converted their sentence data in to text style and performed Japanese-language morphologic analysis on the data using language analysis software. We classified key words, which were created on the basis of the word class information of the Japanese language morphologic analysis, into categories based on causes and characteristics. In addition to this, we classified the characteristics into six categories consisting of those concepts including “knowledge,” “skill and attitude,” “image,” etc. with the KJ method technique. The results showed that the awareness of students of “preparation of drug dispensing” tended to be approximately three-fold more frequent in “skill and attitude,” “risk,” etc. than in “knowledge.” Regarding the characteristics in the category of the “image,” words like “hard,” “challenging,” “responsibility,” “life,” etc. frequently occurred. The results of corresponding analysis showed that the characteristics of the words “knowledge” and “skills and attitude” were independent. As the result of developing a cause-and-effect diagram, it was demonstrated that the phase “hanging tough” described most of the various factors. We thus could understand students' actual feelings by applying text-mining as a new survey analysis technique.
