This study of person fit in attitude surveys was undertaken in order to investigate the influence of the inclusion of misfitting persons on item parameter estimates in analyses using the Partial Credit extension of the Rasch measurement model. It was hypothesised that the inclusion of misfitting persons in data sets used for the calibration of attitude survey instruments might compromise the me...
A method is proposed for the detection of item bias with respect to observed or unobserved subgroups. The method uses quasi-loglinear models for the incomplete subgroup x testscore x item 1 x x itek k contingency table. If subgroup membership is unknown the models are Haberman's incomplete-latent-class models. The (conditional) Rasch model is formulated as a quasi-loglinear model. The parameter...
This study elaborates the Rasch differential item functioning (DIF) model formulation under the marginal maximum likelihood estimation context. Also, the Rasch DIF model performance was examined and compared with the Mantel–Haenszel (MH) procedure in small sample and short test length conditions through simulations. The theoretically known relationship of the DIF estimators between the Rasch DI...
It is shown that application of the Rasch model for equating grades at Basic and Higher Level of Mathematics at General Matura exam in [Hauptman, Metodološki zvezki 7 (2010) 167-181.] is not justified.
A blog quality model has been proposed for bloggers to promote readers satisfaction. However, the model does not determine whether readers consider some quality criteria important, particularly with respect to different blog categories. In this paper, we employed a Rasch analysis to rank the importance of blog quality criteria for the Personal Diary, Socio-political Commentary, Humor/Entertainm...
This study investigated whether mobile learning via Short Message Service (SMS-learning) is accepted by the students enrolled in the distance learning academic programme in the Universiti Sains Malaysia. This study explored the impact of perceived usefulness, perceived ease of use and usability of the system to their acceptability. The survey was constructed using a questionnaire consisting of ...
BACKGROUND Measurement scales seeking to quantify latent traits like attitudes, are often developed using traditional psychometric approaches. Application of the Rasch unidimensional measurement model may complement or replace these techniques, as the model can be used to construct scales and check their psychometric properties. If data fit the model, then a scale with invariant measurement pro...
This study explored the students’ acceptance of Mobile Learning via Short Message Service (SMS-Learning) amongst distance learners in the Universiti Sains Malaysia. This study aims to examine the student’s acceptance towards the language use in SMS-Learning content, the cost of communicating and also the navigation of the system. The study employed the qualitative methodology where data were co...
