Abstract:

Objective To construct a virtual simulation teaching platform of placental abruption based on Jeffries’ nursing simulation teaching theory and implement it in nursing students to explore the effect. Methods A research team was formed，and the expert group discussion method was used to construct a virtual simulation experimental teaching program based on a typical case of placental abruption. Taking into full consideration of the factors of teachers and students，the platform started from three aspects，including simulation teaching design features，teaching practice activities and expected results. Using the convenience sampling method，54 nursing undergraduates of the class of 2019 in an institution were selected as the participants，and the placental abruption virtual simulation experimental teaching platform was applied in the practice and assessment of Obstetrics and Gynecology Nursing course，and data on the use of the teaching platform，the professional knowledge and skills assessment scores，and the evaluation of the students were collected. Results The experimental teaching platform built for premature placental abruption consisted of three parts，including practice training，knowledge mastery assessment and evaluation feedback，with 12 training modules and 20 assessment modules，in which humanistic care content was integrated into several modules. The average time consumed for the whole experiment was 43.39±6.91 min. The average score of the assessment results in the platform was 82.68±10.31 points. The scores for the dimensions of professional theoretical knowledge，operational skills，and humanistic care assessment of students were 4.03±0.64，4.20±0.70，and 4.30±1.13，respectively. A total of 54 questionnaires were issued for evaluation and 52 valid questionnaires were recovered. The scores of nursing students’ satisfaction with the use of the platform，self-confidence，and critical thinking ability were 4.27±0.61，3.89±0.52，3.92±0.59 points respectively. Conclusion Establishing a virtual simulation laboratory teaching platform based on Jeffries’ nursing simulation teaching theory and placental abruption learning syllabus can enrich the laboratory teaching resources for nursing students. Besides，the platform holds advantages in improving the professional skill level of nursing students，cultivating the ability of critical thinking，improving self-confidence in learning，and humanistic care.
