This course is offered via the Internet, distributed DVD's and lab materials in an asynchronous mode. The student will receive instructional information and assignments via these modes and will respond to assignments by submitting work through web forms.
The student must have standard access to the Internet and must have the ability to access the content on the DVD's. The material on the DVD's is accessible using a variety of media players (e.g., Windows Media Player).
The instructor is available via web forms (to which students will be introduced at the very beginning of the course), and will normally respond by the end of the day following your submission (and more typically on the same day) with answers to properly posed questions, feedback on your efforts, and other information. Exceptions may occur in the event of Internet problems or other technical events.
Students with Disabilities
Students with documented disabilities may be eligible for assistance and various accommodations. Please check the Student Support Services link on your Blackboard page.
Note that the course videos as distributed on DVD's do not currently have transcripts, though a version can be provided in which videos are embedded within screen-readable documents. If you require this version of the videos, or transcripts, due to a documented disability, please notify the instructor immediately.
Student Interaction
Students have the opportunity to develop a dialog with the instructor, in the process of submitting assignments.
Students will participate in two series of collaborative lab investigations, serving different functions in various four-member teams.
Other means of student interaction, such as discussion boards, wikis and other standard techniques are not currently a fixed part of the course design, but will be implemented as the need arises.
The broad goals to be achieved by students in the course include the following:
1. Understanding through direct experience, experiment, syntax and mathematical formulation
2. Understanding what it means to validate a hypothesis by an experiment, and specify the precision to which the hypothesis is validated

Use of email: Prior to registration and receipt of initial instructions students my use Email to communicate with the instructor. However email is much less reliable than web forms, and after registration and receipt of initial instructions anything sent through email should first be sent using the appropriate form.
Finding Assignments
Assignments are listed in the Assignments Table. However you are advised to delay viewing the Assignments Table until you have completed the Initial Activities.
Due dates for the various assignments are posted a the Due Dates Page.
A Major Quiz, two regular tests and a final exam will be administered, each receiving a score between 0 and 100%. The lab portion of the course will be graded, and the student's portfolio will be graded, each receiving a score between 0 and 100%. The final grade will be determined by a weighted average of these scores.
Weighting of grades will be spelled out in more detail below, but the algorithm can be stated as follows:
Portfolio and Portfolio Grade
A student's portfolio, consisting of instructor responses to assigned work and/or daily quizzes, will at the end of the term be assigned a grade on a 100-point scale. Each portfolio document is worth 1 point toward the portfolio grade, which will be awarded if the document meets acceptable standards. If the document does not meet acceptable standards, the instructor will request a revision. The total score on the 100-point scale will be equal to the number of points awarded as a percent of the total number of documents assigned. Documents counted toward the portfolio grade include qa's, queries and randomized problems. If this score is higher than the average on the other contributions to the final grade, it will be counted as 1/2 of a test grade (typically around 10% of the final grade); if not it will be counted as 1/4 of a test grade (typically around 5% of the final grade). The actual proportion of the final grade determined by the portfolio depends on weighting contingencies as defined previously and a further explained below.
Grading of Tests
Tests are graded as follows: Each test problem will be graded on a 10-point scale, where 10 points is awarded for a completely correct solution. Partial credit is given for partial solutions. Raw test scores will be normalized to the following scale, according to the difficulty of the test, as specified in advance of each test by the instructor:
A: 90 - 100
B: 80 - 90
C: 70 - 80
D: 60 - 70
F: Less than 60.
Grading of Labs
The body of each student's lab work will be graded and will be assigned a grade on a 100-point scale. This grade will be given a weight equal to 1 test grade. Every lab counts toward the final grade.
Each lab activity is worth a certain number of points, with point values specified in the Assignments Table.
A typical lab activity includes setup, obtaining and reporting data, analysis of data and interpretation of results. Some activities include only some of these aspects. In any case results are to be reported in a valid format, often a format specified by lab instructions. The weighting of the various aspects of a lab report will include only those aspects relevant to the activity, and those present are weighted as follows:
Each aspect will typically be awarded a value of 0, 1 or 2, with 2 representing acceptable work, 1 representing marginal work and 0 representing unacceptable work. For exceptional work a value of 3 might be awarded.
To determine full-credit score for a lab the 'acceptable' value 2 will be multiplied by the weight of each aspect present, and the products added to obtain the full-credit score.
Earned credit is obtained multiplying the value awarded for each aspect present by the weight of that aspect, and the products added to obtain the earned-credit value.
The score on the lab will be the earned credit as a percent of full credit.
The contribution to the total lab grade will be the resulting percent of the point value of the lab.
The lab grade for the course will be the sum of the contributions of the labs as a percent of the total point value of all labs.
Ungraded Assignments
Assignments not included in the above categories are not graded. However information obtained from those assignments is often necessary in order to understand various lab situations and assigned problems, and to prepare for tests. Information in ungraded assignments may necessary to answer questions in Query documents.
Requirement of Passing Lab Average
Furthermore, in order to earn at least a C in the course a student must have a passing lab grade (i.e., a lab grade greater than 60 on the 100-point scale). A student whose lab grade is not passing will receive no higher than a grade of D for the course.
Final Grade
The final grade will be a weighted average according to the above guidelines. An alternative summary of the weighting is as follows:
Major Quiz: Weight .5 or 1.0, to the advantage of the student
Test #1: Weight 1.0
Test #2: Weight 1.0
Comprehensive Final Exam: Weight 1.0 or 2.0, to the advantage of the student
Portfolio Average: Weight .25 or .50, to the advantage of the student.
Lab grade: weight 1.0 or 20% of final grade, to the advantage of the student, and lab grade must be passing to earn a grade of C or better.
The table below summarized the calculation of course grades:
assessment weighting contribution to total score major quiz 1/2 <= m_weigh <= 1 test score * m_weight test 2 1 test score * 1 test 3 1 test score * 1 final exam 1 <= f_weight <= 2 final exam score * f_weight lab grade L_weight = 1 lab grade * L_weight portfolio 1/4 <= p_weight <= 1/2 portfolio score * p_weight total of weightings total of contributions Final average = total of contributions / total of weightings
Final grade will be determined by final average, subject to the condition that the lab grade must be passing in order to receive a grade of C or better. A failing lab grade will result in a grade not better than D for the course.
