Student Content Assessments
Instrument 19: Beckman-Coulter P/ACE MDQ Capillary Electrophoresis (CE) Evaluation
Project: Instrumentation for Instruction in Analytical Separations
Trinity University
Funding Source: NSF - Undergraduate education (DUE)
Purpose: To assess the effectiveness of incorporating capillary electrophoresis (CE) throughout the chemistry curriculum.
Administered To: Students using Beckman-Coulter P/ACE MDQ capillary electrophoresis instrument in a laboratory course.
Topics Covered:
- Background Characteristics & Activities (Student): experience with the instrument
- Content Specific Assessment: Chemistry: instrumentation-capillary electrophoresis (CE) for separation of materials
Format/Length: 5 open-ended questions
This questionnaire is being given to all students using the Beckman-Coulter
P/ACE MDQ capillary electrophoresis instrument in a laboratory course. Your
answers on this form will be used to assess the effectiveness of
incorporating this instrument throughout the chemistry curriculum. This is a
required procedure as described in our grant proposal to the National Science
Foundation. The NSF provided funds for 50% of the cost of the P/ACE MDQ.
Your answers will
not be used to grade your performance in the laboratory course, but rather
to grade the NSF project. Your instructor may require that you complete the
form by some means but will not grade individual questions. Please answer
each question to the best of your ability. If you do not know the answer
to a question, simply state that you don't know. We are not interested in
grading you but finding out and recording what you know about this
instrument and technique. Use as much space as is necessary (use the back
of this form or attach extra sheets) to provide a complete answer or the necessary
explanations.
This study has
been approved by the [your university/college name here] Institutional Review Board. If
you have any questions regarding the approval, please contact Chair
[your university/college name here] IRB (999-xxxx). Your answers will be kept confidential. Your
participation involves no risks or benefits to you.
