Using evidence and reasoning to support claims: Students’ identification of acids and bases



Jana Jensen, Melanie Cooper
The purpose of this study is to investigate students’ ideas about acids and bases as part of a larger study on the how students develop the ability to determine chemical and physical properties from molecular structure. This study builds on previous acid-base research by investigating students’ ideas about acids and bases in two different general chemistry course: a reformed course called Chemistry, Life, the Universe, and Everything (CLUE), and a more traditional course. Students from both courses completed open ended questions about acids and bases, and their responses were analyzed using qualitative research methods. Results will be reported including the evidence and reasoning students use to back up their claims about the strength of acids and bases.
