CURRENT SUMMER 2022 COMPOSITE SCHEDULE This is a very, very, very tentative version of the SSI 2022 schedule, combining regular and "second" or Zoom-based "lab" meetings, JIT/MINI deadlines, and Individual and Team HOMEWORK deadlines at this point. Other events may be added as we progress. Keep in mind this schedule could change at any time. Such changes will first be announced clearly in class. [LAST REVISED: Sunday, June 5, 2022]

  • Summer Session 2022: Active Course Engagement, Final Averages and Final Grades posted and submitted. Final Grades are posted on Canvas and have been submitted to the Registrar. They should be visible to you on One.IU tomorrow, 6/21/22.

    VERY IMPORTANT REMINDER ABOUT CANVAS-CALCULATED FINAL GRADES: Please be sure you are clear that the averages for each of the components of your final average and the final average itself that is displayed on Canvas is accurate. I have been able to modify the final grading scale used by Canvas to match the one explained below, so all Canvas posted scores are correct.

    For your Active Course Engagement score, the maximum possible score was 100, and consistent with my comments early in the course, while you didn't have to be talking all the time to get a good score here, you had to be in class, use the course resources, follow course guidelines, and submit all course work. A vast majority of Active Course Engagement scores were in the 90s, but a few were in the 80s or 70s. The class average on Active Course Engagement was 93.00%. It is important to remember, however, that there is no way to completely separate Engagement from attendance, full use of all course resources, completion of all work, and compliance with all course guidelines. If you were not doing all these things, there is no way you could be actively engaged.

    Please read the following carefully: After careful consideration, I have made the following adjustment to the original 90-80-70-60 grading scale. I took into account the usual lower averages on the HW assignments as each student and as the team learn to write as required because this is part of the learning experience. I also considered the averages for the course as a whole in all the other areas. As a result, I modified the grading scale in the following way. I dropped the entire scale by 3 points to 87-77-67-57. So the lowest A- went from 90.0% to 87.0%, the lowest B- from 80.0% to 77.0%, and the lowest C- went from 70% to 67.0%. The upper and lower 2.5% of each range still determined the +/- grades in each range. As previously noted, your average is not just adding all the points and dividing by the total. It used the weighted values you can find on the General Information page of the website that are accurately calculated by Canvas as your "Final Average".

    NOTE: This represents an adjustments in the grading similar to what I have made in this course in the past. I think it is what I can fairly justify. No further adjustments will be made.

    ALSO keep in mind these adjustments to the grading scale are based on two separate considerations. First, I look carefully at how each group of students performs from term to term. Second, as just noted above, I have to maintain a connection to some sort of absolute scale of what constitutes work of superior, acceptable, and unacceptable quality. In other words, I do not merely adjust the grading scale to get a certain "number" of A, B, or C grades. The adjustments are made and then the grades are determined. NOTE on "borderline" grades. In this course, borderline would be from .1% or .2% (tenths of a percent) away from the next highest grade, not 1% or 2% or 3% (whole percentage points) away. This is based on the fact the grading scale has already gone through a very carefully considered adjustment. Every grade was reconsidered individually by me and anyone who was close to borderline was rechecked by me at least once, if not twice. If any one of the major categories upon which you were evaluated had an average well below that next grade level, then no changes were made. If you had any missing work (especially without notice or explanation), then the higher grade was not considered. All other relevant considerations were taken into account when considering an adjustment.

    Consistent with my statements during the first week of class that it is a huge challenge to get an A in this course but a hard working consistent student can earn a B. It turns out that this summer session, as a group, you were a very good group of students and I think the overall grade distribution reflects that. That speaks highly of each of you and your dedication to doing your best work in this course. The A338/A538 combined final grade distribution was a combination of B and C grades only, with 6 B+, 3 B, 0 B-, 1 C+, 0 C, and 0 C-. Again, this is one of the better class-wide performances I have had in this course in recent years.

    Thanks to everyone who participated in the course this summer. I always enjoy doing this class and really appreciate having such a great group of students. I know this course is a huge amount of work, especially during the compressed summer schedule, but I think you will see that it will pay off in many ways in the future. It was my goal that each of you found something valuable in what we worked on together. I hope you have a great rest of the summer, whatever you may have planned, and best of luck in whatever your future holds.

  • Final Project and Final Assessment Scores posted and emails sent:

    NOTE on A338/A538 Team Assessment Scores You should have received an email with your Final Project Evaluation and Final Team Assessment forms attached. PLEASE NOTE: The Team Assessment averages were outstanding overall. Please remember, as noted in my email, your score is a 50 + 50 composite of the quantitative feedback you got from your teammates (and self) and my evaluation of the qualitative feedback you gave your teammates (and self). The scores ranged from 98.17 to 86.58 with scores entirely in the 90s and 80s. There were 9 in the 9s and 1 in the 80s. All of you clearly learned from the HW4 assessment experience and provided detailed and useful feedback to your teammates, including the "WHY" for the qualitative components and, therefore, did very well.

    The Team Final Reports were both very good submissions that each also had a number of inadequacies. It is certainly clear a great deal of work went into not only the research but the structure and composition of these documents. One scored in the 80s and one in the 70s which is as good a pair of reports as I have seen in a long time. As is common, however, far too many parts were simply lacking in detailed discussion and/or explanations, so there was no foundation for any of the recommendations. In other cases, no recommendations were even offered or required sections or topics were basically "glossed over." Some recommendations were counter-intuitive and no explanation was offered to justify any such an unusual recommendation. The "two competing prices" aspect was under represented or or omitted completely which made it difficult to accept the recommendations offered. Again, there were many, many strong sections, so there still represent far stronger efforts than most of those I have seen in previous versions of this course. It was very, very good work.

    I will be taking time to consider the Active Course Engagement scores as well as any adjustments to the final grading scale. That information to be posted sometime tomorrow (Monday) at the same time that I submit the Final Grades to the Registrar. PLEASE NOTE: I realize you may be looking at your current average and have concerns about your Final Grade. Keep in mind what you currently see on Canvas does not include your Active Course Engagement score nor does it reflect any adjustments I will make in the final grading scale. Please be patient and allow me time to consider these rather than contacting me with concerns that are not well founded at this point. I appreciate your cooperation with this.

  • CAT 10 scores posted and CAT Averages on Canvas confirmed correct. OFFICIAL Attendance Averages also posted: Just a quick note to let everyone know I have posted the CAT 10 scores and confirmed that the CAT averages on Canvas match my records. The CAT average is based on 10 CAT exercises totally 118 points. The class average was 65.25, which may seem like a very low average. It is actually one of the higher averages I have seen in this course for this component. There were 6 averages in the 70s, 3 in the 60s, 1 in the 50s and 1 below 50. The class average is a combination of some CATs that did not go will for the class as a whole as well as individuals who happened to miss class when a CAT was administered.

    I have also posted the OFFICIAL Attendance average as mentioned in our final meeting. This is a combination of the 28 regular meetings + 12 Second meetings that we had. As also mentioned, any excused absences counted neither for nor against your average. The class average was 96.25%, with 7 scores of 100, 2 in the 90s, and one below 90.
