be undertaken, encompassing the participation of students, lecturers, and

raters. The findings from both tests indicate that, following the

implementation of suggested improvements, all products of the model are

deemed suitable for usage. Subsequently, an initial trial was undertaken on

the model's product, encompassing the participation of students and raters, to

evaluate the fit of the items and the consistency among the raters. According

to the MFRM analysis, the instrument build is deemed appropriate based on

the MFRM criteria. Aside from that, there is no variation in how raters assign

grades to students' writing. This demonstrates that the raters have

comprehended the statements contained in the developed rubric.

B. The Results of Model Evaluation and Revisions

This section presents the result of the main field testing in addressing the questions

relating to the qualities of the construct of the assessment instruments for assessing

students argumentative writing (RQ 3b) and the consistency between raters in

giving the scores (RQ 3c). The main field testing was carried out through the cycle

of the CAR. Therefore, the researcher discusses the procedure for incorporating the

GBA-TBI Model and blended learning into the instructional framework

before empirically examining the qualities of the assessment instruments and the

inter-rater reliability.
