of both items were further assessed using the Rasch model. In summary, all

instruments have been duly verified as being genuine and reliable tools for

aiding students in the process of evaluating their drafts and enhancing their

language skills.

C. The Quality of the Model and Users’ Voices

This part addresses the final research statements with three research questions about

how the students benefit from the implementation of the model, the students writing

profiles, and their perspectives on adopting the model. The perspectives of the

lecturers are also elaborated. The enhancements in the learning quality and student

learning outcomes, particularly the quality of the students’ argumentative writing

indicate that the developed and implemented model satisfies the criteria for

effectiveness and practicality (Plomp, 2013), which are elaborated in the following

sub-sections.

1. The Quality of the Model Implementation

The model's quality influences the ease of use by students and lecturers in

designed teaching and learning activities, the results of which can improve

the quality of student learning outcomes (Plomp, 2013). Similarly, Akker

(van den Akker, 2013) stated that the practicality of a product refers to the

degree to which users consider the product clear and usable. Widihastuti and

Suyata (2014) also stated that the practical analysis of the model could be

identified from the model's implementation, which was 76% (excellent).

According to this definition, operational practicality in this research can be
