The Alice Lee Centre for Nursing (ALCNS)
at NUS uses the problem-based learning
(PBL) approach for its undergraduate nursing
programme. ALCNS has been keen to integrate
simulation technology into PBL to provide
opportunities for nursing students to apply
theories learnt from the PBL session to real
life situations. The main focus is to develop
students’ clinical competency in providing safe,
competent, timely and appropriate patient care
during crises.
Nurses need to be competent in identifying
patients at risk and implementing immediate
interventions to manage crises. Although the
clinical laboratory and clinical practicum in
the preregistration nursing curriculum provide
nursing students with valuable learning
experiences, they may not be exposed to clinical
crises during such sessions. Technological
advancement in nursing education has allowed
the use of a human patient simulator, which is
able to simulate a variety of patient conditions
and create opportunities for students to learn
how to manage an unexpected situation in a
planned and prescribed way. One of the major
strengths of simulation-based learning is thatit provides students with hands-on practice in
solving ‘real life’ problems without the fear of
harming a ‘real’ patient.
With the support of CDTL’s Teaching
Enhancement Grant, a quasi-experimental
crossover study was conducted to evaluate
the use of a simulated learning activity in
teaching nursing students how to identify and
manage a crisis. It was hypothesised that the
clinical performances of nursing students who
had experienced a simulated learning activity
during PBL discussion would be superior to
those who had only completed conventional
PBL discussion.
First year nursing students in the Bachelor of
Science (Nursing) programme, who undertook
a nursing module on caring for patients with
respiratory and cardiovascular disorders, were
assigned to either a simulated situation with
problem-based discussion (SPBD) or problem-based
discussion (PBD) group for their PBL
scenarios on respiratory and cardiac cases.
Both SPBD and PBD groups worked on the
scenarios in a 2-hour brainstorming session
where students attempted to identify clinical problems and develop hypotheses and learning
issues through group discussion. Students then
had time for self-directed learning to research
their assigned ‘learning issue’. Group members
reconvened during the following week to
re-examine the scenarios. The PBD group
discussed their learning issues and information
to resolve the crisis presented in the scenarios.
SPBD students reconvened and went through a
hands-on session to manage the crisis using the
high-fidelity SimMan patient simulator. This
was followed by a debrief in which students
discussed findings from the individuals’
learning issues and how the situation might
have been managed more effectively.
Following the completion of each case
scenario, students were invited to sit for a test
on systematic assessment and management of
a simulated patient in a crisis. A total of 30
nursing students participated in the first test
related to a respiratory scenario and 33 nursing
students participated in the second test related
to a cardiac scenario. Their performances were
scored using validated checklists. The mean
scores of students who had gone through SPBD
was significantly higher than those who went
through the PBD (see Table 1).

group
The study supports the use of simulation
with problem-based discussion as a more
effective way of teaching students how to
identify and manage a crisis as compared to
the use of problem-based discussion alone.
There are several reasons the integration of
simulation into problem-based discussion
results in superior learning outcomes. One
is that simulation provides learners with an
opportunity to practise their clinical skills in a
realistic and non-threatening environment. This
allows them to review and practise their skills
as a whole and develop a systematic approach
to crisis management (Weller, 2004). Repetitive
practice is crucial for clinical skill acquisition
as it makes skill demonstration effortless and
automatic (Issenberg & Scalese, 2005). In this
study, students in the SPBD group were engaged
in repetitive practice after their clinical skills
laboratory.
In addition, simulation facilitates contextual,
constructive and active learning. The transfer
of learning from paper to a realistic clinical
situation through simulation enhances contextual
learning in PBL. The clinical experiences
gained from the simulation allowed students to
link these experiences to their discussion of the
problem. This enabled students to build more
personal interpretations of the problem and
thus, enhanced the problem-based discussion
(Mamede, Schmidt & Norman, 2006). Also,
the simulation, which involves a variety of
learning strategies such as role play, videos
and discussion, enhances the learning outcomes
in PBL by engaging students. Jeffries (2002)
stated that using a variety of learning strategies
in simulation can accommodate students’
diverse learning styles, which is an important
pedagogical principle of good teaching.
According to Hodgson (1997), learning is
deepened when learners are able to perceive the
meaning and intrinsic relevance of the subject
matter to their own purposes. Immersion into
the nursing role through simulation provides
students with more valuable insights on the
relevance of their clinical skills and knowledge
in their field of work.
