To build your knowledge of survey design, you will work in a group on a survey development project. The project involves developing research and survey questions; the project and your contribution to the group together are worth 50 points.

I really believe that students and instructors should be on the same team, with the goal of learning. I see grades as a tool to motivate learning. Our goal will be to provide feedback that helps you to learn.
This course will follow a "self-assessment" philosophy. I am more interested in helping you to learn things that will be useful to you than in assigning grades. In general, I think that my time is much better spent in providing better feedback and in being available to work through problems together.


There are 500 points in the class, distributed across assignments as follows:
The university still requires grades, so you will be leading the evaluation of your work. This will be completed with me in three stages, at the end of weeks 5, 10, and 16. In each stage, you will use [[Self Assessment Reflection|this form]] to reflect on what you have accomplished thus far, how it has met, not met, or exceeded expectations, based both on rubrics and personal goals and objectives. At each of these stages you will receive feedback on your assessments. By the end of the semester, you should have a clear vision of your accomplishments and growth, which you will turn into a grade. As the instructor-of-record, I maintain the right to disagree with your assessment and alter grades as I see fit, but any time that I do this it will be accompanied by an explanation and discussion. These personal assessments, reflecting both honest and meaningful reflection of your work will be the most important factor in final grades.


{| class="wikitable"
We will use the following rubric in our assessment:
|+ Assignment points
|-
|Midterm Exam
| 100 points
|-
|Final Exam
| 100 points
|-
| Survey Design Project
| 50 points
|-

|-
| SPSS Quiz 2

|-

|-

|}


Your final course grade will be calculated using the following scale:  
* 20%: class participation, including attendance and participation in discussions and group work
* 20%: Labs and homework assignments
* 25%: Exam
* 35%: Final Project


<div style=display:inline-table>
The exam will be graded like a normal exam and the score will make up 25% of your grade. For the rest of the assignments (and the other 75% of your grade), I will provide feedback which will inform an ongoing conversation about your work.

My interpretation of grade levels (A, B, C, D/F) is the following:
| 484-500 points
 
| A+
 
|-
A: Reflects work the exceeds expectations on multiple fronts and to a great degree. Students reaching this level of achievement will:
|464-483 points
* Do what it takes to learn the principles and techniques of social networks, including looking to outside sources if necessary.
| A  
* Engage thoughtfully with an ambitious final project.
|-
* Take intellectual risks, offering interpretations based on synthesizing material and asking for feedback from peers.
|449-463 points
* Share work early allowing extra time for engagement with others.
| A-
* Write reflections that grapple meaningfully with lessons learned as well as challenges.
|-
* Complete all or nearly all homework assignments at a high level.
|434-448 points
 
| B+
B: Reflects strong work. Work at this level will be of consistently high quality. Students reaching this level of achievement will:
|-
* Be more safe or consistent than the work described above.
|414-433 points
* Ask meaningful questions of peers and engage them in fruitful discussion.
| B
* Exceed requirements, but in fairly straightforward ways - e.g., an additional post in discussion every week.
|-
* Compose complete and sufficiently detailed reflections.
|400-413 points
* Complete many of the homework assignments.
| B-
 
|}
C: This reflects meeting the minimum expectations of the course. Students reaching this level of achievement
</div>
will:
<div style=display:inline-table>
* Turn in and complete the final project on time.
{| class='wikitable'
* Be collegial and continue discussion, through asking simple or limited questions.
|-
* Compose reflections with straightforward and easily manageable goals and/or avoid discussions of challenges.
|384-399 points
* Not complete homework assignments or turn some in in a hasty or incomplete manner.
| C+
 
|-
D/F: These are reserved for cases in which students do not complete work or participate. Students may also be
|364-383 points
impeding the ability of others to learn.

|349-363 points
