assessment, concept inventories, misconceptions, inquiry learning in the laboratory, and children learning chemistry

Assessment of Student Learning. We develop instruments to measure cognitive and affective dimensions of learning. We are interested in students' misconceptions (particularly regarding representations) and metacognition (learning how to learn). concept inventories focused on multiple representations acid-base reactions atomic emission, flame tests, & energy level diagrams covalent and ionic bonding representations enzyme-substrate interactions organic acid strength oxidation-reduction reactions cross-validation studies of published instruments to reduce assessment fatigue Inquiry & Laboratory Learning. We investigate learning in the laboratory and design guided inquiry experiments for analytical, inorganic, organic, and biophysical chemistry courses. measuring meaningful learning in the laboratory faculty cognitive, affective, & psychomotor goals for learning in the laboratory concepts and inquiry as pathways to learning chemistry for at-risk students inquiry experiments: spectroscopic properties of metmyoglobin polymerized monolithic columns for HPLC microwave synthesis of liquid crystals symmetry elements & symmetry operations retention mechanisms in LC extraction and TLC of anthocyanidins Students in the Bretz CER Group co-design their research projects, and in doing so, have the opportunity to learn a wide variety of research skills and techniques: survey design and item development statistics, classical test theory, and item response theory semi-structured interview and observation protocols qualitative data analyses human subject protocols software packages such as SPSS, NVivo, Livescribe
