Appendix 6. Flowchart of utilization MUSTe method

The MUSTe assessment process commences with the collection of users’ demographic information using the ‘Pre-test Questionnaire’ via the MSUTe tool (see Appendix 3). Pre-test Questionnaire is followed by the VE training. In this training stage, users will gain firsthand experience of interacting with variety of I/O devices and interfaces. Users should be able to operate the VE to perform simple tasks and practice with more complex tasks. ‘Self-efficacy Questionnaire’ will be distributed to the users to report their self-efficacy beliefs about their ability to perform tasks in the VEs. This follows a training assessment of users task performance. As marked “1”, this assessment of user performance is software and application based, and a logging tool will record each user’s performance in detail. All the relevant objective measures in this regard will be used as inputs to the VE efficacy assessment. A ‘Perceived VE efficacy Questionnaire” will then be distributed to the user, to rate their perceptions of interaction and learning experience as well as how well system facilitate their learning. Finally, ‘Memory Test Questionnaire’ will be used, after a gap of approximately two weeks time, to assess the memory performance of the user. This objective measure tests users’ ability of recognition and recall based on their interaction and learning experience with the VE. Gathering of critical data will proceed to the decision of ‘assessment depth’ by the evaluator.

It is noticeable that the evaluator plays a minor role in the MUSTe evaluation. As marked in “2”, the evaluator could observe user performance in the VE and note down any usability problems he/she found. However, the evaluator’s observation notes and feedback will not be used in the final stage of system efficacy determinates. Therefore, if the time and budge is limited for the evaluation this step can be omitted.

Once, all required evaluation data is obtained, MUSTe tool can perform data analysis on quantitative and/or qualitative data (if coded) and determine cognitive, skill-based and affective learning outcomes, depending on the purpose, time, cost and the depth required. When assessment based on quantitative data is satisfactory, the MUSTe tool will enable variety of quantitative and statistical analysis and determine the system efficacy, and produce an efficacy score. This often refers to an ‘Analytical evaluation phase’. On the other hand, if in-depth assessment is preferable and a single score is considered unsatisfactory, the evaluator can analyze qualitative data, as marked “3” in the flowchart, to achieve a more in-depth assessment.This analysis will yield deeper understanding of user experience and interaction with the VE, and enable the evaluator to provide detailed analysis of problems identified. The evaluator can transfer the analysis result on the qualitative data to the MUSTe tool. When combined with the quantitative results, the system efficacy can be determined with great detail referring to the ‘Holistic evaluation phase’. As addressed before, the data analysis can stop at either of the ‘Analytical evaluation phase’ or the ‘Holistic evaluation phase’ determining VE’s efficacy, depending on the purpose, time, cost and thoroughness.

Appendix 7. MUSTe: The Software Engineering Tool


MUSTe supported a wide range of data collection and analysis at varying levels of complexity. MUSTe tool supports data entry and data analysis, as well as produces variety of evaluation results. An example of a MUSTe window, screen shot (a) shows a pre-test questionnaire screen, where users could quickly enter their demographic information via this tool. Similarly, other MUSTe user perception measures can also be collected quickly and electronically during experimentation or user testing, without any interpretation to the evaluation process. Screenshot (b) gives an example of a utility function of a post-VE questionnaire, which enables the evaluator to check missing data of a specific user or gain an overall view of the completeness of the data collection. The utility functions also enable an evaluator to check the completeness of video recorded. It is also possible and easy to associate a user input data with his/her video recorded task performance (c).
