2.1 Learning experience
2.1.1 Novel forms of assessment stimulate learning interest and increase learning engagement
The ER style of assessment was presented in the form of a game. Most of the interviewees reported a feeling of anticipation regarding the ER method of assessment. The fun and novelty of the assessment format motivated the nursing students. Respondent E commented that "the ER is a little bit more fun and newer than the regular assessment, and there is a certain degree of challenge." Respondent B expressed that "I like it more because it is full of unknowns, and I like games that are challenging." Respondents said that they would also spend additional time on prior review because the ER format aroused the desire to win. Respondent C: "If you want to win, you drive yourself to solidify some of your knowledge and be more prepared."
2.1.2 The new assessment format provides a relaxed atmosphere and diminishes the role of the invigilator
Most of the interviewees stated that the ER teaching method to evaluate the basic skills of nursing ensured a relaxed atmosphere. Thereby, it reduced the psychological pressure, which not only led to efficient use of the knowledge acquired, but also improved the students' motivation to review and consolidate their knowledge at the end of the examination. Respondent F stated that "participating in this is a little bit more relaxing than taking the regular examination. It is a little less tense and promotes the feeling and desire to participate more."
On the other hand, although the teacher was still involved in this assessment, the teacher's role changed. Thus, it weakened the role of the teacher as an invigilator during regular examinations, which also relieved the students' stress and tension. Respondent D remarked that "this way, you won't be so nervous that you forget all thee memorised knowledge."
2.1.3 Group work improves communication skills and collaboration
Narrating their experience, all 12 interviewees mentioned that the ER assessment format amplified teamwork and strongly tested students’ coordination and cooperation. Respondent H observed that "the members in a group need to work closely with each other during the assessment process." Some interviewees said that compared with the conventional assessment, the ER teaching method emphasised cooperation among group members, and this cooperation lasted from the pre-preparative phase to the assessment process. According to respondent D, "perhaps each of our group members has a different focus, and we may divide the work when reviewing and preparing."
2.1.4 Integration of theory and practice to enhance clinical thinking
When talking about the advantages of the ER teaching method, some interviewees reported that, compared with the conventional assessment method, applying the ER teaching method to the nursing operation assessment is flexible due to the combination of theoretical knowledge with practical application, which also led to a more comprehensive assessment. Respondent B expressed that "I think that the ER format promoted better combination." The ER style integrates theoretical knowledge with operational skills into cases, which simulated clinical scenarios and inculcated clinical thinking. According to respondent B, "I think that this format is quite good, and the assessment content is also richer; in addition to operational skills, it also involves a lot of theoretical knowledge. A few complete cases test our clinical judgment and resilience."
2.3 Learning feedback
2.3.1 Improvement of the clustering mechanism
The grouping method of this assessment was based on free combination. Some interviewees mentioned that such a grouping method was somewhat unreasonable, which failed to guarantee randomness of the groups and potentially affected the subsequent assessment of performance. In addition, some interviewees thought that the number of participants (4-6) in each group was more reasonable, and that too many or too few people might make it impossible to analyse individual performance fairly. Respondent H expressed that "in the groups, the number of participants might be higher, which prevented analysis of everyone's performance, and perhaps everyone's tasks would be distributed unevenly."
2.3.2 Process needs to be improved
The interviews revealed that most students had experienced ER games before, while some students never played them or understand the process. Students who lacked gaming experience spent longer to familiarise themselves with the game and process after the assessment started, which not only weakened the sense of participation of some students, but also dampened their motivation, and ultimately affected the results and learning outcomes. As respondent D stated, "because I haven't experienced it before, I was a little bit confused when I went in. "
