There has been a general dissatisfaction among some faculty at many institutions for some time in the more-or-less traditional "cookbook" type of General Chemistry course. A common thread suggests that "the opportunity to excite students and show them how real science is done [is] squander(ed)".1
This class of Honors and Majors students is among the first at Temple University to engage the problem at the Freshman level.
Additionally, there is now a great deal of evidence that the process of "Cooperative Learning" profits most students. It is hoped that this class will provide the Chemistry Department with some evidence for its value here. The text book chosen for the laboratory is M. M. Cooper Cooperative Chemisty, McGraw-Hill 1996 which is available at the T.U. Bookstore. You must also bring a hard bound laboratory notebook and safety glasses to class and a Safety Release Form found in the Student Guide to CST Laboratory Safety.The Guide can be obtained from the Copy Center in Conwell Hall, Room 601.
In addition to the textbook ( M. M. Cooper Cooperative Chemisty, McGraw-Hill) library resources found in the Chemistry Department Library and on the World Wide Web may prove useful in this course.
Some web resources2 which you might find useful include (but are not limited to):
The laboratory work in this course is divided into a series of projects. As outlined below there will be four (4) projects to be completed. The first laboratory period will be devoted to a discussion of the goals and objectives of the course, checking into the laboratory, investigating some of the equipment available in the laboratory, and organizing the class into teams. (It is becoming common in today's workforce for teams to form, dissolve, and reform to attack specific problems.) Team members will be introduced to each other and initial roles in the team assigned. Your role in the group will vary with each assignment. Subsequent laboratory sessions will adhere to the schedule appended below.
THE TEAM APPROACH1
As our society becomes more complex, it is becoming clear that most problems that beset us can no longer be solved in a reasonable amount of time by single individuals working alone. So, learning to work as part of a team is an important undertaking.
In our individualistic society, working as part of a team is often found to be difficult because members of the team are expected to rely upon each other to solve problems cooperatively. Today, widespread cooperation is particularly true in the sciences where an individual laboratory often cannot house all of the equipment necessary for the solution to every problem. Therefore, although this is a course in problem solving, it enjoys the added complexity of attempting to utilize a team approach to solve the problems. Thus, each team will be presented with a problem and the members of the team will need to devise their own experiments, test their own hypotheses and evaluate their own data. Although all of the teams will have the same problems, it is anticipated that different teams will find different solutions.
As noted above your role in the team will change. At some time you are expected to assume the role of:
PROCEDURAL OUTLINE
During the first week of lab, you will be assigned to a group. You will then spend some time getting to know the members of your group and aquainting yourselves with the laboratory and various places in the building where facilities to support your enquiries are housed (library, computer room , etc.). You will also be given your first project and will spend whatever time remains of the rest of the laboratory period working on your project. Before the beginning of the next laboratory period your group will hand in a brief (200 - 400 words) written preliminary proposal describing how your team anticipates carrying out the project. The proposal, which should be made jointly and can be submitted by email (david.dalton@temple.edu) should explain what you intend to do, why you intend to it, and how you will deal with the results. It must be submitted no later than the Friday prior to the week in which you will do the work. It has been suggested 1 that you will almost certainly need to modify your preliminary proposal during the work. This preliminary plan will count for 10% of the total grade of the first project and, along with an oral report and final summary, will be the only portion of your grade which will be assigned to the group as a whole.
During the next several weeks, your group will continue investigations into your project and at the beginning of week four, you will each hand in a separate report on the progress made to date. Each member of the group will write a separate report and will receive feedback the following week. The final report for the project will be due from each member of the group the week following the final lab period of each project.
Each project is evaluated separately. The total grade for the course is the average of the project grades.
GRADING:
Each project will be graded along the following outline:
|
ASSIGNMENT |
VALUE |
|---|---|
|
Proposal |
10% (group grade) |
|
Weekly Summary |
5% (group grade) |
|
Preliminary Report |
10% (individual grade) |
|
Final Report |
40% (individual grade) |
|
Technique and Notebook |
10% (individual grade) |
|
Oral Report |
15% (group grade) |
|
Peer evaluation |
10% (individual grade) |
|
TOTAL |
100% |
NOTE:
Attendance is the laboratory is required. If you must miss a laboratory for some reason, you should inform the members of your group and the instructor (david.dalton@temple.edu). Your group members will have the option of requesting that you do extra work (e.g., looking things up in the library, etc.). If you have more than two unauthorized absences, the instructor may encourage you to withdraw from the course. In any event, each of you will have the opportunity to evaluate the members of your group at the end of each project.
INCOMPLETES/WITHDRAWAL
Subject to the restrictions of the University schedule students may withdraw from the course without penalty (Grade of "W") or with a failing grade (Grade of "F" . If you find you must withdraw, please inform the instructor (david.dalton@temple.edu). and the members of your group so that they can attempt to make arrangements to accommodate your loss from the group. Please make every effort to show consideration for those who are staying with the course. Note that you must check out of the laboratory before a drop authorization is signed or you will be charged a fee and your grades will be withheld pending its payment.
The grade "I" (Incomplete) will be given only to students who have finished three of the four assigned experiments. Obtaining the grade "I" also requires a signed form (available from your instructor or academic advisors) indicating the reason for the grade "I" and stating specifically what work remains to be done and by what date the work will be completed. Failure to provide such a form will result in the grade "F" being submitted at the end of the term.
If you do not wear your safety glasses in the laboratory you will not be permitted to stay.(Persons wearing contact lenses must remove them and replace them with eye glasses for the laboratory period.) You must read and agree to abide by the Safety Rules provided for you in your laboratory text (pp 14 - 16) and you must bring to class a signed Safety Release Form found in the Student Guide to CST Laboratory Safety that is obtained from the Copy Center in Conwell Hall, Room 601.

2 At this writing (January 2003) all of the www sites quoted are "up-and-running". However, it is the current nature of the www to be somewhat ephemeral and therefore, of course, there are no guarantees that the sites now present will be there when you need them. Additional sites can be added should members of the class find them particularly useful.
3 Laboratory reports (group and individual) will be considered submitted if they have been placed in the instructors' mail box in the Department office (BE201) or received by email (which is not necessarily the same as the time it was sent) by the time specified in the Schedule. Students in the laboratory scheduled to meet on Friday afternoon have the option of submitting their report by email (david.dalton@temple.edu). before noon on the Saturday following their laboratory or submitting it as noted above by 9:00 AM on the Monday following their laboratory.
