    Input: Introduction Virtual environments offer a variety of benefits and may be a powerful medium with which to provide nursing education . The objective of this study was to compare the achievement of learning outcomes of undergraduate nursing students when a virtual patient trainer or a traditional lecture was used to teach pediatric respiratory content . Methods This was a r and omized , controlled , posttest design . A virtual pediatric hospital unit was populated with four virtual pediatric patients having different respiratory diseases that were design ed to meet the same learning objectives as a traditional lecture . The study began in Spring 2010 with 93 Senior I , baccalaureate nursing students . Students were r and omized to receive either a traditional lecture or an experience with a virtual patient trainer .  Students ’ knowledge acquisition was evaluated using multiple-choice questions , and knowledge application was measured as timeliness of care in two simulated clinical scenarios using high-fidelity mannequins and st and ardized patients . Results Ninety-three students participated in the study , of which 46 were in the experimental group that received content using the virtual patient trainer . After the intervention , students in the experimental group had significantly higher knowledge acquisition ( P = 0.004 ) and better knowledge application ( P = 0.001 ) for each of the two scenarios than students in the control group . Conclusions The purpose of this project was to compare a virtual patient trainer to a traditional lecture for the achievement of learning outcomes for pediatric respiratory content . Although the virtual patient trainer experience produced statistically better outcomes , the differences may not be clinical ly significant . The results suggest that a virtual patient trainer may be an effective substitute for the achievement of learning outcomes that are typically met using a traditional lecture format . Further research is needed to underst and how best to integrate a virtual patient trainer into undergraduate nursing education Objective . To determine whether using 3-dimensional ( 3D ) technology to teach pharmacy students about the molecular basis of the interactions between drugs and their targets is more effective than traditional lecture using 2-dimensional ( 2D ) graphics . Design . Second-year students enrolled in a 4-year masters of pharmacy program in the United Kingdom were r and omly assigned to attend either a 3D or 2D presentation on 3 drug targets , the β-adrenoceptor , the Na+-K+ ATPase , and the nicotinic acetylcholine receptor . Assessment . A test was administered to assess the ability of both groups of students to solve problems that required analysis of molecular interactions in 3D space . The group that participated in the 3D teaching presentation  performed significantly better on the test than the group who attended the traditional lecture with 2D graphics . A question naire was also administered to solicit students ’ perceptions about the 3D experience . The majority of students enjoyed the 3D session and agreed that the experience increased their enthusiasm for the course . Conclusions . Viewing a 3D presentation of drug-receptor interactions improved student learning compared to learning from a traditional lecture and 2D graphics Objective : This study examined the independent effect of a patient 's weight on medical students ’ attitudes , beliefs and interpersonal behavior toward the patient , in addition to the clinical recommendations they make for her care . Design : A total of 76 clinical -level medical students were r and omly assigned to interact with a digital , virtual female patient who was visibly either obese or non-obese . Methods : Interactions with the patient took place in an immersive virtual ( virtual reality ) clinical environment that allowed st and ardization of all patient behaviors and characteristics except for weight . Visual contact behavior was automatically recorded during the interaction . Afterward , participants filled out a battery of self-report question naires . Results : Analyses revealed more negative stereotyping , less anticipated patient adherence , worse perceived health , more responsibility attributed for potentially weight-related presenting complaints and less visual contact directed toward the obese version of a virtual patient than the non-obese version of the patient . In contrast , there was no clear evidence of bias in clinical recommendations made for the patient 's care . Conclusion : Biases in attitudes , beliefs and interpersonal behavior have important implication s because they can influence the tone of clinical encounters and rapport in the patient – provider relationship , which can have important downstream consequences . Gaining a clear underst and ing of the nature and source of weight bias in the clinical encounter is an important first step toward the development of strategies to address it Virtual reality ( VR ) simulation provides a means of making experiential learning reproducible and reusable . This study was design ed to determine the efficiency and satisfaction components of usability . Previously , it was found that first year medical students using a VR simulation for medical education demonstrated effectiveness in learning as measured by knowledge structure improvements both with and without a head mounted display ( HMD ) but students using a HMD showed statistically greater improvement in knowledge structures compared to those not using a HMD . However , in this current analysis of other components of usability , there were no overall significance differences in efficiency ( ease of use ) , nor in satisfaction , within this same group of r and omized subjects comparing students using a HMD to those not using a HMD . These types of studies may be important in determining the most appropriate , cost effective VR simulation technology needed to achieve specific learning goals and objectives 
    Output:
    
Several systems such as Second Life , VisCube and Oculus Rift provide the users with an opportunity to don the role of a virtual avatar and enable users to respond to different situations and circumstances in a virtual world .
This provides an opportunity for the users to gain knowledge and experience specific situations that , under normal circumstances , might not always be possible .
VRE offers several advantages , especially in healthcare professional education .
For example , the simulation of a virtual disaster site could help medical trainees experience the intricacies and difficulties faced during a disaster and can help prepare them in a virtual world .
Study ing anatomy structures in a VRE could help trainees underst and and appreciate the structural complexities of certain organs such as the inner ear .
