Web-based Storage, Manipulation, and sharing of Electronic Data from the Chemistry Lab
Symposium: About the General Chemistry Laboratory
Session: Session 3 of 4: General; Monday, July 31st, 2006

Paper Start Time: 15:45:00
Author: Estel Sprague
Presenter: Estel Sprague

Abstract: The purpose of this presentation is to describe a convenient system for storing, manipulating, and sharing the large amounts of electronic data often generated in modern chemistry lab experiments using MeasureNet® data collection equipment. The system allows data sets to be easily and automatically uploaded directly from the laboratory into one or several individual, password-protected student accounts on a remote server. Students retrieve their uploaded data sets later using any web-connected computer. When desired, the instructor can provide data analysis assistance by means of Excel workbooks containing macros written for specific types of data. Sharing of data by groups of students is greatly facilitated, since data sets can be saved for all members of a group, giving each student access to all of the data sets uploaded by the group. Illustrative examples of the use of this system will be presented.

Practical Laboratory Final Exams Featuring MeasureNet to Assess Student Learning
Symposium: General Chemistry: Improving General Chemistry Instruction Through Lab Practical Assessment
Session: Session 1 of 1

Paper Start Time: 09:45:00

Abstract: During Fall semester 2005, we implemented Laboratory Practical Final Examinations into the General Chemistry laboratory curriculum to assess students’ mastery of chemical concepts, basic laboratory techniques, and their ability to implement the scientific method. We observed some unusual patterns in students’ abilities to perform certain types of laboratory techniques. For example, a majority of students were able to determine the concentration of an unknown acid via titration, but relatively few students were able to determine the concentration of an unknown base via titration. Understanding the reasons for these observed differences will allow instructors to enhance their students’ laboratory learning experience.

Workshop: MeasureNet – The High School Setting
Fee: None

Room: BRWN 2134

Workshop Start Time: 08:00:00 - 11:00:00

Leader: Edmund Escudero
CoLeaders: Edward Kentrup

Description: Experience Measurenet. Hear how the system is used in two different high school settings. Course use ranges intro. physical science through AP Chemistry and AP biology. While at the workshop you will have the opportunity to perform a series of experiments that demonstrate the broad range of overall experiments available with the system.
