The What Is Happening In this Class? (WIHIC) questionnaire is a
multidimensional measure for assessing the classroom learning environment based
on student perspectives. The purpose of this study was to validate an Indonesian
version of WIHIC and to assess the instrument’s psychometric properties by using
confirmatory factor analysis (CFA) and the Multidimensional Partial Credit Model
(MPCM), one of the family of Polytomous Rasch model. The Indonesian WIHIC
was administered to 962 high school students (368 male, 594 female), aged 14-18
years, in Jakarta, Indonesia. Results from the CFA model comparison showed that
the 7-dimensional factor structure of WIHIC was satisfactory. We performed
MPCM and found that this model fit the data of the Indonesian WIHIC reasonably
well. Moreover, the estimated Rasch person separation reliabilities of each
subscale showed that WIHIC has good internal consistency (0.87 to 0.96). The
Indonesian WIHIC questionnaire appears to be a valid and reliable tool for
assessing the classroom learning environment in Indonesian high school students.
