Construction of digital network platform of morphology of laboratory medicine and its application on clinical teaching / 中华医学教育探索杂志

ABSTRACT

Objective:To explore the digital network platform construction of morpghology of laboratory medicine and its effects on clinical teaching.Methods:Laboratory morphological inspection pictures of peripheral blood, bone marrow slices, urinary sediments, parasites, secretions, cavity effusion, medical microorganisms and chromosome specimens were collected to build a digital network platform for online learning, practical training, and examination by applying Authorware multimedia software, Access database, and Web interface. Afterwards thirty interns on laboratory medicine were randomized into two groups traditional teaching group and software teaching group for morphological assay examination. The differences in theoretical scores, exam time, practical operation scores, and satisfaction rates between two groups were statistically analyzed by t test and Pearson Chi-square test using SPSS 13.0. Results:The software teaching group showed significantly higher theoretical and practical scores [(88.0 ± 6.4); (85.3 ± 7.1)] than traditional teaching group [(76.3±8.1); (80.3±7.9)] (both P=0.000 1), and its theoretical exam time [(93.7 ± 10.5) minutes] was significantly shorter than traditional teaching group [(115.8±16.2) minutes] ( P=0.033 8). The questionnaire survey results showed that software teaching group showed higher satisfaction rates in the aspect of teaching content systematization, diversity of teaching methods, clinical learning interest and fairness of assessment than traditional teaching group, with statistical significance ( P<0.05). Conclusion:The software teaching model could improve quality and efficiency in teaching morphological assay, enhance students' learning autonomy and professional skills, and provide a powerful platform to adapt to vocational innovation of laboratory medicine education.
