The attitude of students towards computer programming learning is a subject which is not widely researched in the current literature. In fact, there is little generally accepted scale, which is tested and accepted in terms of reliability and validity in literature in order to measure the attitude of students towards computer programming learning. The aim of this study is to develop a valid and reliable scale. The development process consists of two phases that utilize two different sample groups. The sample group, in the first case, consists of 496 students and it consists of 262 students in the second case. In order to detect the validity of the scale, exploratory and confirmatory factor analyses, item factor total correlations, corrected correlations and item discriminations were conducted. The reliability of the scale is justified using the internal consistency level and reliability level. ASCOPL is a 5-point Likert-type scale, consisting of 20 items, grouped under three factors. The results indicate that ASCOPL is a reliable and valid scale in order to measure student attitudes towards computer programming learning.
