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' satisfaction with foreign language lessons in a valid and reliable manner. The research was conducted on three separate study groups consisting of 460 students in the spring semester of the 2017-2018 academic year. In the research, firstly, an expert 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 the 59.97% of the total variance. These factors were named as follows: the Curriculum, Teaching Staff and Physical Conditions. 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 high level of meaningful correlation was observed between these values. Internal consistency and split half test values for the whole scale show that the scale is highly reliable. Based on these findings, it can be said that this scale is a valid and reliable measurement tool for university students to measure their satisfaction with foreign language lessons.
