The law of conservation of matter is a cornerstone in the development and advancement of modern chemistry. With this idea in mind, a test of four items was designed and used to determine students’ understanding about the conservation of matter in open and closed-system chemical reactions. The test was administered to…

Improving students’ conceptual understanding depends on the question types asked in exams by the teachers. In the related literature, in order to analyse the cognitive levels of the questions, Bloom’s Taxonomy has been mostly used. The aim of this study was to analyse and compare the chemistry questions asked in exams…
