I rushed to new campus after conducting 45 minutes of my Design Aesthetics class this morning.
After settled down in the Lab 4 in IT Centre, I began to learn what is Rasch Model with the facilitation of Dr Ong Yoke Mooi and Dr Sharon Lee Leh Hong.
Herewith my personal ILOs:
- to explain what is Rasch model
- to elaborate the usage of Rasch model and analysis
- to depict how Rasch model can be applied in my field of research.
Lessons of the day:
1. Rasch Model can be used to balance games, i.e., balancing the difficulty level of in-game challenges over time.
2. The concepts of infit and outfit can be borrowed and used in Csiksentmihalyi's flow channel, in which outfit are in-game challenges that are beyond the flow channel, which could either be too easy (that leads to boredom) or too difficult (that leads to anxiety).
3. For items tested through Likert scale (i.e. more than "yes" or "correct" and "no" or "incorrect"), dichotomous model still relevant because we can code the outcome of each item to either 1 or 0.

Up to this moment, I think I can use Rasch Model to design, develop and test questionnaire items, specifically to examine whether a item is appropriate to be included in the questionnaire or now.
