Methods： A high-fidelity teaching simulation on clinical nursing practices using intelligent human analogues was conducted with 200 students, and The Simulation Design Scale, and the Student Satisfaction and Self-Confidence in Learning Scale developed by the National League for Nursing were used to evaluate the training effectiveness and its influencing factors. Results： For the high-fidelity teaching simulation, students gave scores of 4.36± 0.54 points for satisfaction and 4.33 ± 0.46 points for Self-Confidence. The students highly rated the five dimensions of teaching design, i.e., teaching objectives/information, assistance/support for students, problem solving, guided feedback, and fidelity. The teaching design was closely correlated with the satisfaction of the high-fidelity teaching simulation and self-efficacy, and the dimensions of teaching objectives/informa- tion and assistance/support for students were particularly strong predictors of teaching effectiveness. Conclusions： A high-fidelity teaching simulation based on Jeffries＇ theoretical framework improved student satisfaction with the simulation and their Self-Confidence. In planning simulations, teachers should take into account five characteristics, i.e., teaching objectives/information on simulation education, assistance/support for students, problem solving, guided reflection, and fidelity, to achieve better teaching effectiveness.展开更多

This violates the cultivation of communicative competence, and is not in conformity with the society’s requirements of applied foreign language talents. Cognitive linguistics theory, which links language form with semantic concept, reveals the internal relation of man’s thinking and language. If we can subtly apply cognitive linguistic theory into Japanese grammar teaching to explore the cognitive process in the speakers’ brain while expressing, we can get a good understanding of diffi cult points and “special case”.
