Development of Foreign Language Lesson Satisfaction Scale (FLSS): Validity and Reliability Study

In this research it is aimed to develop an instrument that could be used to measure university students' satisfactionwith foreign language lessons in a valid and reliable manner. The research was conducted on three separate studygroups consisting of 460 students in the spring semester of the 2017-2018 academic year. In the research, firstly, anexpert opinion was applied for the content and face validity of the scale prepared in accordance with literature review,student and expert opinions. In the final form, exploratory factor analysis (EFA) and confirmatory factor analysis(CFA) were applied. The EFA yielded a construct that consisted of 28 items and three factors that explained the59.97% of the total variance. These factors were named as follows: the Curriculum, Teaching Staff and PhysicalConditions. CFA was performed in the final application phase and the fit indexes were determined to be acceptable.For the criterion validity, the correlations of the factors with the total points of the scale were calculated and a highlevel of meaningful correlation was observed between these values. Internal consistency and split half test values forthe whole scale show that the scale is highly reliable. Based on these findings, it can be said that this scale is a validand reliable measurement tool for university students to measure their satisfaction with foreign language lessons.
