Text: |
The Biological Chemistry of the Elements: The Inorganic Chemistry of Life, 2nd ed., by J.J.R. Fraústo da Silva and R.J.P. Williams, published by Oxford University Press, ISBN 0-19-850848-4 (2001). |
|
|
Coverage: |
We will not have time to assimilate everything from this book. Student interests will help guide the selection or omission of topics for class discussions and individual presentations. |
|
|
|
|
Speaking-intensive approval: |
This course has been approved by the Committee on Instruction to be offered in a format that fulfills the speaking-intensive criteria within the general education requirements for a B.A. degree at Lawrence University. |
|
|
|
|
Rationale for this course: |
A far-ranging subfield of bioinorganic chemistry has burgeoned over the past three decades, leading to important understanding that the molecular details within living systems comprise far more subtlety and complexity than seen solely from the vantage point of “organic” molecules and “biochemical” processes. Several metallic elements are utterly indispensable to life, but in exceedingly tiny amounts in very specific forms; sometimes a different form or an excess of that same element can be lethal. Indeed, there are significant interdisciplinary linkages to medical interventions, toxicological problems, and environmental issues both localized and global that curious minds might explore. This course provides a scientifically disciplined way in Lawrences’s curriculum whereby interested students can engage with such topics and concerns through reading, writing, and especially oral expression. |
Since books in this area are closer to the monograph model than the textbook model, students regardless of background will need help decoding, assessing, and assimilating information. Students having different prior strengths in biology, chemistry, or environmental science will be encouraged and guided in offering peer support in and out of class. Speaking as scientist-to-scientist will be emphasized from the outset, with expectations increasing up to taking major responsibility for well-prepared presentations drawn from later chapters of the book. This will model the way that professional scientists actually interact and help one another with new or unfamiliar concepts, theories, and data. |
|
|
|
|
Class meeting format: |
Class discussions will be student-originated and student-centered without formal lecturing. Virtually daily participation will be expected. Examples would be explaining a table, figure, paragraph, or longer segment from the book. Peer questioning will also be expected, both as another form of participatory activity and as a direct assessment of success in explanations. The instructor may “play dumb” and draw out further depth and clarity of explanation. The instructor may assign grades to several short talks and larger ones given later by each student. |
There should be frequent challenges, mediated by peers as well, to ensure that oral exposition is clear, authoritative, and responsive to questions raised by others. When peers appear not to understand, they ought to articulate the origins of their difficulty since active listening and careful reading are both important. |
|
|
|
|
Assessments: |
If this were not a speaking-intensive course, then frequent problem assignments, two in-class exams, the final examination, and an optional individual project would form the basis for evaluation. |
| Assignments | 45% |
| Hour exams | 30% |
| Final exam | 25% |
| Optional project | displace 5–15% |
|
As it is, however, we should probably plan to modify this scheme. In particular, the “project” will not be optional; rather, each student will have principal responsibility for at least one major presentation drawn from the book, as noted above. |
Ordinarliy the instructor would cite the cumulative distribution of grades for this course in previous years, but this is a fairly new course (and type of course). Past percentages would be merely history, in any event, and would in no way represent quotas or promises for this year. |
In seeking to make this course “speaking intensive” the instructor had to respond to the questions “What percentage of the final course grade is based on oral work?” and “How will feedback on oral work be given?” and responded as follows: At least one-third. Lots of informal critiquing in class. Individual office appointments to take up any personal issues not appropriate for public comment. Perhaps an occasional written paragraph inviting self-reflection and either a written or oral response. |
|
|
|
|
Assignments: |
In a typical science class, there might well be six to eight assignments, coming along after every two or three class meetings, but we may have somewhat fewer. |
Assignments are due at 1:00 PM on the stated day. Late work will be handled as follows: Each student will begin the term with a “contingency” account containing 10 “contingency points.” When an assignment is late, this account reduces at the rate of 2 points per calendar day (or fraction thereof). If an assignment can be completed nicely and handed in earlier than 5:00 PM preceding the stated due date, then additional contingency points can be accrued at a rate of 1 per calendar day. The contingency account uses signed integer arithmetic. At the end of the term, the balance may be used to resolve ultimate grading decisions, but there is no predetermined relationship of contingency points to the standard grading scale. |

|
Honor code: |
Each piece of work that you submit in this course should bear the Lawrence University honor pledge, your signature, and the date of completion on the final page. |
Please seek help from others whenever you can learn effectively in the process, but always acknowledge the source, nature, and extent of assistance or collaboration. The final product should be distinctively your own. |
|
|
|
|
Assistance: |
CHEM/ENST 247 is a challenging opportunity intended for mature students who can seek out assistance well in advance of the fabled “point of desperation.” Please bring any ambiguities about expectations or any lack of understanding from class meetings to the instructor’s attention immediately. |
Lawrence’s Center for Teaching and Learning has some resources of potential usefulness to students in speaking-intensive courses at the Communication link. When you go to the Center to look over those resources, you might also consider offering yourself as a subject-matter tutor for students struggling with other courses. Tutoring can be a relevant and rewarding experience for building your confidence in oral exposition. |

Tentative schedule (2010-11): |
The pace will be brisk. Procrastination can be fatal. Keep up! Although the book has 20 chapters, the schedule shown below reflects a slower pace that does not finish the book by the end of the term. And try to sustain a healthy balance. |
