Two-tier tests are such as assessment tools that can make available for teachers/researchers to determine students alternative conceptions and whether a student gives a correct response to a question by understanding the related subject since the secondtier of a test asks for a reason for the first-tier response. The…

Science is taught as a core subject through schools around the world. While the content and subject sequences are more or less similar, every country has developed along different paths as a result of unique cultural and political influences. It is important to study not only the present international science educatio…

This study examines undergraduates' understanding of some concepts in solution chemistry such as unsaturated, saturated, and supersaturated solutions; physical properties of solutions; and gas solubility. A diagnostic test concerning these concepts was developed and administered to 107 participants. Nine students were…
