Assessing Students' Conceptual Understanding of Solubility Equilibrium.
Peer reviewed Peer reviewed
Raviolo, Andres – Journal of Chemical Education, 2001
Presents a problem on solubility equilibrium which involves macroscopic, microscopic, and symbolic levels of representation as a resource for the evaluation of students, and allows for assessment as to whether students have acquired an adequate conceptual understanding of the phenomenon. Also diagnoses difficulties with regard to previous…

Testing, Testing: Good Teaching Is Difficult; so is Meaningful Testing
Peer reviewed Peer reviewed
Toby, Sidney; Plano, Richard J. – Journal of Chemical Education, 2004
The limitations of teaching and assessment of knowledge are emphasized, and an improved method is suggested to test the students. This superior examination technique would replace multiple-choice questions with free-response questions for numerical problems, wherein the numerical inputs fed in the computer would be optically scanned and graded…

Cafeteria-Style Grading in General Chemistry.
Peer reviewed Peer reviewed
Goodwin, John A.; Gilbert, Brian D. – Journal of Chemical Education, 2001
Introduces a "cafeteria-style" grading (CSG) approach in science instruction which allows students to decide on the course components and their weight in evaluation. Considers student success, motivation, and self-awareness for the evaluation of CSG. Uses portfolios, writing assignments, web page development, and traditional evaluation methods for…
