This paper describes the output and processes involved in the development and validation of instrument as a tool for assessing students’ experiences in the field study subject consisting of three phases; (1) construct definition and item development, (2) face validity and (3) pilot testing of the instrument. By reviewing related literature and models of experiences of students on their field study, constructs or latent variables were defined operationally as basis for item development. For construct validation, factor analysis was used to assess the internal structure of the instrument and reliability was assessed using Cronbach’s alpha coefficient as measure of internal consistency of the items. Factor analysis of the students’ responses yielded a four – factor solution accounting for 70.38% of the total variance in the responses. Based on initial classification and nature of items, these 4 dimensions of the students’ experiences of field study course were identified as follows: (1) orientation, (2) instruction, (3) experience, (4) evaluation. The findings suggest that the final version of the questionnaire can be utilized in attaining the purpose, and the information derived from experiences of students’ may be used as a basis for more informed decision concerning field study subject for both basic education and field study teacher.
