dc.description.abstractProblem Statement: Research has shown that attitudes have important role to estimate and develop achievement. Therefore, attitudes should be measured in valid and reliable way. As literature show, attitudes towards science can be measured in two ways: general science attitude and attitudes towards physics, chemistry and biology. When previous psychometric studies in measuring attitudes towards science examined, it is seen that exploratory factor analysis is used to analyze construct validity generally. However, after performing exploratory factor analysis, confirmatory factor analysis needs to be used to test whether models estimate expected theoretical constructs. This study used exploratory as well as confirmatory factor analysis in order to fill a gap in the literature while examining attitudes towards specifically biology course instead of general science attitude. Objective: The purpose of this study was to develop Likert type scale for measuring attitudes towards biology course while examining construct validity and testing the fit between independence model and the hypothesized model through confirmatory factor analysis after performing exploratory factor analysis. Methods: Data were collected from three different high schools in Edirne. The questionnaire was administered to two hundred and seventy students, but 32 subjects were not included in the sample because of missing value and double filling on answer sheets, decreasing total number of subjects to 238. 148 of students were male, 98 were female. Students were between 15 and 19 years old (M = 16.42, SD = .57). Results: It was considered that the scale of attitude towards biology course had unidimension construct as the result of exploratory factor analyses and confirmatory factor analysis was performed to analyze validation of theoretical construct for further analysis. Results show that the scale had unidimension construct. Accordingly, internal consistency reliability analysis was performed. Cronbach alpha was .94 which indicates a high internal consistency. Finally, psychometric results of 'Biology Course Attitude Scale' showed that scale had construct validity and reliability. Recommendations: It is recommended that 'Biology Course Attitude Scale' be used in different studies by different researchers to analyze the validity and reliability of the scale for further contribution to the field.en_US
