The content validity was ensured by experts by comparison to the outcomes included in Turkish eighth grade curriculum. After the biotechnology subject was taught, the BKS was administered to a sample of 155 eighth grade students in three groups in Ankara in 2019-fall semester. The Cronbach alpha reliability coefficient of the BKS was calculated to be .770.
