The objectives of this research are: 1) to find out the quality of existing

writing materials for office administration students and 2) to describe the

development of WEFO E-book in teaching writing for Office Administration

students. 

This study was a Research and Development (R&D) study adapted the

R&D model proposed by Borg and Gall (1983) as cited in Sugiyono (2015) with

some modifications consisting of exploration stage and product development

stage. Exploration stage describes: (1) the quality of existing writing materials in

the textbook used at Office Administration study program and (2) the Office

Administration students’ needs toward writing materials.  Meanwhile, the product

development stage informs: (1) the prototype development process, (2) the result

of expert judgment toward the prototype, and (3) the result of the prototype tryout.

The data in the exploration stage were obtained by conducting theoretical review,

interview, questionnaire, observation, and document analysis. Meanwhile, the data

in the model development stage were obtained by conducting observation, Focus

Group Discussion (FGD), questionnaire, and expert judgment. The data of

questionnaire were analyzed quantitatively using frequency and percentage. The

data from document analysis, interview, observation, and FGD were analyzed

qualitatively using interactive model which consists of data collection, data

reduction, data display, and conclusion drawing. 

The finding in exploration stage showed that the existing textbook is not

closely concerned with the aims of Office Administration study program in

Vocational High School. The book is not composed based on Office

Administration students’ need.  The material, situations, topics, and vocabularies

of the book provide general English which are not suited to teaching and learning

situation in Vocational High School. Based on the data of need analysis, the

students need the writing materials which are suitable for their study program so

those materials can be useful in their future career after graduation. 

The product of this study is supplementary writing materials entitled

“WEFO (Writing English for Office) e-book” for eleventh grade students of

Office Administration study program in Vocational High School. WEFO e-book

was developed by considering several aspects: aim, content, material organization,

design, and accessibility. WEFO e-book consists of four chapters, “Business

Letters”, “Application letter and CV”, “Personal Letter”, and “Memo” which are

based on the Office Administration students’ need toward writing materials. Each

chapter consists of pre-writing, drafting, responding, editing, and reflection

activities. The prototype was validated by the content expert and instructional

expert. The prototype was tried-out and revised to get the feasible product. After

going through three trials, it could be concluded that the prototype is feasible for

teacher to teach, for students to study, and for developing the indicators of

writing.
