The final version of the test was reviewed by two science teachers and an academician whose expertise is in science education. Anyproblematic items were revised. The reliability of the achievement test was calculated based on the data obtained from the pilotimplementation. If the Cronbach’s Alpha coefficient is between 0.00 � α < 0.40 interval, the scale is not reliable; if it is between 0.40 �α < 0.60 interval, the scale’s reliability is low; and if it is between 0.60 � α < 0.80 interval, the scale is quite good (Doymus¸, 2009). Asthe achievement test’s Cronbach’s Alpha value is 0.678, it can be accepted as reliable
