The Final for this class is scheduled for Thursday 30 April at 11 am.
If you have a learning or physical disability that might affect your performance in this class, please inform me and the
Coordinator of Disabled Student Services at x3609, to verify your status and provide you with appropriate assistance.
My objective for this class is that you begin to understand the reasoning behind how we know what we think we
know about earth history and history of life through time. We will be interested how different lines of evidence are
assembled to construct models of the earth in the past, and what are the assumptions of these models. You will express
your developing understanding of lecture and lab material (i.e., lines of evidence) and assigned readings through short
papers on assigned topics, prepared and submitted monthly. By keeping a journal you will develop fluency in writing and
develop your own thoughts on this material. At least once in the semester you will be given responsibility for leading the
class in discussion on some aspect of the assigned reading.
Grading: With the exception of the final (see p. 4) there will be no tests. Approximately once a month you will be
responsible for turning in a typed 1500 word paper on one of several assigned topics, based on lecture, lab or assigned
reading (paper 1: 1000 words). Hard copies of papers are due at the beginning of the Thursday class. Each paper is
also to be turned in as a MS Word document attached to email message. Papers submitted after the due
date will have a letter grade penalty/day late: Turned in Friday (- 4 points/40); turned in Saturday (-8 pts); Sunday (-12
pts); Monday (-16 pts), etc.
Subject heading of the email MUST be GEOL 102-(yourlastname)-Paper1 (or 2,3,4,5): GEOL 102 Smith
Paper 1. The document MUST be titled GEOL102(firstfourlettersoflastname)P1: GEOL102SmitP1.
Every two or three weeks discussions will be held on F&W and Fortey assigned readings. Students will be given
responsibility for leading discussion and are expected to participate. Students not leading discussion must submit a
detailed outline of the assigned reading to earn any credit. Absence from more than one discussion will
result in an F for the class.
A threaded discussion will be hosted on the Blackboard website for this class. Each student will be responsible for
initiating at least two threads on a content area and at least three meaningful responses to posts. At least one posting
must be made per month.
Laboratory: 10 points/week may be scored in the Laboratory. Scores will be based on written lab exercises.
Absence from more than two labs will result in an F for the class.

There are a lot of new concepts in historical geology. Many of these concepts challenge long-held assumptions or
beliefs of enrolled students. Writing is emphasized in this class to hone students’ thinking, critically evaluate beliefs
and insights, improve students’ ability to identify and solve problems, begin to understand others’ perspectives, reduce
stress, and improve health. Focused practice in writing increases fluency, and increases motivation to write. Your
instructor believes that the techniques we practice in the historical geology class hold the potential of transforming
your studies for the remainder of your formal studies and can carryover to your future professional career and
personal life.
Specifically we will keep a journal and prepare five papers.
1) Each student will be responsible for completing five papers on topics in Historical Geology.
a) Each student will be responsible for meeting with the instructor (15’) at least three times (once/week) before each
paper is due. Students will be responsible for scheduling these appointments using a schedule on the instructor’s office
door. These appointments will provide an opportunity for reviewing outline or concept map for the paper,
appropriate documentation, and difficulties in paper preparation and review of an initial draft. Students are well
advised to come prepared for these meetings with a typed paper draft of what has has been done.
3 points will be awarded for each visit for as many as 3 meetings/paper. If the student makes all 3 meetings / paper, the
student will earn 10 points (Only 2 meetings for paper 1). Typically thesis statement + outline should be
complete by wk 1; body paragraphs and any thesis revision wk 2; and conclusions and
introduction complete by wk. 3.
b) Spelling, grammar issues, awkward sentences / construction will not be addressed by the instructor. The instructor
will mark in the margins, errors or problems he identifies. These marks will be counted (and up to
10 points) will be subtracted from the paper total based on that count. Students can identify for themselves (or visit
the Writing Room) the errors, and correct them and return the corrected paper with the marked original to regain as
many as 10 points on the first three papers, only if they have made all three paper meetings; this “rewrite” (including any
improvements in content) is due within a week of the time the papers are returned to the class. Paper 4: content and
no more than 5 grammar points can be improved for a grade. Paper return date will be written on the top of the first
page. It will not be possible to resubmit Paper 5.
c) The remaining 20 points will be based on the content of the paper. The paper must have a thesis that is supported
by later paragraphs, and must have a conclusion. Each paragraph must have a topic sentence. Each topic sentence
must be supported by or documented by observations. When geologic observations are cited, the age, location,
formation(s) must be listed. Observations must be separated from interpretations within the papers. Those
interpretations must be supported by the observations in the paragraph. When outside sources are used they must
be appropriately and consistently cited. It is best to exhaust the class/ lab notes and texts before
turning to the internet. Figures are valuable to illustrate difficult concepts. These must be drawn by the student
either by hand (and photo’d, scanned in, inserted in the document) or drafted using a computer drawing program.
No figures are to be cut/ pasted in from websites. No new information is to be introduced in the
conclusion. The student’s goal is to document mastery of a chosen topic. Another handout offers
additional suggestions.
2) Each student in historical geology will maintain a dated, reflective journal.
a) Maintenance of this journal and its entries will be worth 10% of a student’s final grade in Historical Geology. It is
recommended that journal entries begin in the back of the student’s notebook if a bound or spiral notebook is used; if
a student uses looseleaf pages, it will probably be best to integrate journal entries with class and lab notes, perhaps
setting these entries apart by boxing them with a highlighter. While customarily journal entries are private, and the
maintenance of the journal is for the student’s use and benefit, for the purpose of assessment the instructor will collect
and mark the journal and its entries. The instructor understands that journal writing is personal, informal and should
not necessarily conform to the expectations of other academic writing. Additionally for some assignments, students
may be asked to read and discuss (each other’s) specific journal entries in pairs or groups of three. Some journal
entries will be completed in class; some journal entries will be done outside of class. A student should plan to
make at least two entries in the journal/week.
b) Journals will record the student’s response to material introduced in lecture, lab, and assigned reading. It is
expected over the course of the semester students will use techniques including freewriting, focused freewriting,
listing, logs, dialog, concept mapping, metaphor and metareflections. These techniques will introduced and reviewed
during assignments during the semester.
c) The “quality” of journal entries is expected to improve over the course of the semester. By quality, I mean clarity
of thought, grasp of formal content, quicker identification of problems, and what data are needed to solve those
problems.
