peer-assessment papers, a test, and analytic scoring rubrics. They were all

equipped with a grid to aid validators in understanding the contents of the

examined instruments. All instruments should be presented in the appropriate

content, organization, and presentation to ensure students learn well (Nunan,

1989). Furthermore, the model implementation guidebook is a reference for

users to ensure proper model usage. This procedure must be followed for the

implementation objectives to be met. The process of validating the content

involved several experts

3. Validation of the Initial Model Design

This section elaborates on responses to a part of the third research problem,

emphasizing the product quality, particularly content validity, as evaluated by

experts.

a. Teaching-Learning Devices

The multipurpose assessment model seeks to improve teaching-

learning to enhance students' writing skills, particularly writing the

argumentative texts. Consequently, teaching-learning devices, such as a

lesson plan and student worksheets, are required to support the assessment

procedure. In addition, a protocol for observing the processes was

included.

In this study, the implementation of the model was incorporated

into the GBA-TBI and FCA learning cycles. The instructional plan was

developed considering the students’ writing issues raised in this study's
