Developing an Assessment Instrument for Indonesian EFL Teachers Performance Based on the Students Perceptions

The absence of an instrument specifically usable to measure Indonesian EFL Teachers performance has inspired the researchers to develop a valid and reliable instrument based on the students perceptions. A two-phase research activity has been conducted to reveal a newly developed instrument. The first research has been conducted to identify the qualities an effective Indonesian EFL Teacher should possess, and the weak points an ineffective Indonesian EFL Teacher performs during his or her classroom teaching. A think-aloud technique of data collection was used, whereby 86 first year semester students of English Department were asked to report their educational experiences in learning English with favorable and unfavorable EFL teachers. A number of qualities for an effective EFL teacher and a number of weak points for an ineffective EFL teacher were identified from their reports through a coding process. Based on the identified qualities and weak points, a questionnaire draft is developed. The draft was then scholarly validated and, then, tested to 100 senior high school students to find out its reliability index. Finally, the researchers successfully reveal a 44 item-questionnaire with reliability index of 90.4. This indicates that the newly developed instrument is valid and reliable to measure Indonesian EFL Teachers performance. With this instrument, school management is recommended to use the instrument to assess their Indonesian EFL teachers performance.
