Exam 2 results

Exam 2 results are now posted on Canvas (and released to your Examsoft student portal)! The mean was 91% in case you’re wondering. I hesitate to post the mean because I don’t curve grades, and I don’t want to encourage you to compare yourself to each other. But I know you like to see it so there you go.

I’ve gone through all the questions, and I found two that didn’t perform well. Here they are:

32. The foramen ovale allows blood to flow from:
A. This answer got cut off 😦
B. The right ventricle to the left ventricle
C. The left ventricle to the right ventricle
D. The right atrium to the left atrium
E. The left atrium to the right atrium

The correct answer was D. Here are slides 52 and 53 from the Cardiovascular System lecture, which describe the location and purpose of the foramen ovale:

One problem with this question is that the first distractor didn’t show up properly. But more importantly, only 39% of the class answered the question correctly. The last learning objective was about the foramen ovale (“Explain the function of the foramen ovale and describe what happens to it after birth.”) – and I thought that it would be a fairly straightforward question – but when less than half of the class gets a question right, it indicates to me that I probably didn’t describe this well enough in class, or stress the importance of it. So I’ve added a point to everyone’s score for this question.

18. The lymphoid system gets rid of all of the following EXCEPT:
A. Microorganisms
B. Cancer cells
C. Waste products
D. Dead cells
E. Foreign materials (like pollen)

The correct answer was D. Here’s slide 5 from the Lymphoid System lecture, which describes what the lymphoid system gets rid of:

The first learning objective was about the functions of the lymphoid system (“Briefly describe the functions of the lymphoid system.”). However, only 40% of the class got this question right (24% of the class chose A, microorganisms). One student mentioned that dead cells seemed like something the lymphoid system got rid of, because the red pulp of the spleen gets rid of old red cells – and I bet there were other students that thought the same thing. Technically, the red cells the spleen gets rid of aren’t dead…but they’re almost dead! So I can see why that would be confusing. I gave everyone an extra point for this question too.

Let me know if you have any questions about this exam, or if you want to go through it with me!

Information about Exam 1

This post contains specifics and logistics for our first exam in General Histology (DDS 6214). Please email me if you have any questions not answered here! I’ll send out an email with the password to the exam tomorrow night.

Start and end time

The exam is scheduled for Thursday, September 1, and you may take it any time between 12:01 am and 11:59 pm that day. Once you open the exam you have two hours to complete the exam. All submissions must be uploaded by 11:59 pm on Thursday in order to receive a grade.

Classroom availability

Our classroom should be open and available from 1:00 – 3:00 pm tomorrow, if you want to take the exam at that time in our classroom. I’d suggest that if there are several people in the the room, please try to space yourself out well so there’s no way anyone (including ExamMonitor) can suggest the possibility of you looking at someone else’s computer 🙂

Content

I aim for roughly 5 questions per lecture hour on our exams (in this class and in our future classes). For this exam, the Intro to Histology lecture was quite short, so I only have two questions on that lecture. Here’s the full breakdown by lecture:

Intro to Histology: 2 questions
Embryology: 5 questions
Epithelial Tissue: 10 questions
Muscle Tissue: 10 questions
Nervous Tissue: 5 questions
Connective Tissue: 5 questions
Cartilage and Bone: 10 questions

Please take a look at the Sample Exam Questions post to get an idea of how I write questions. There will not be any tissue microscopic images on the exam, but as I mentioned in class, there will be an electron micrograph image of the sarcomere on the exam. Questions 17 and 18 in the Exam 1 Review Kahoot, and question 4 in the Sample Exam Questions post show this image and give you an idea of the kinds of questions I might ask on the exam.

Examplify Information

You will take this exam using Examplify installed on your PC/Macintosh laptop or desktop computer. If Examplify is currently installed, it may require an update and computer restart before the exam. If it is not installed, you should download and install the most up-to-date version of Examplify before the exam.

This exam will be remotely proctored using ExamID and ExamMonitor. This means you will take a photo of yourself at the start of the exam for identity verification and you will be recorded during the exam. So only laptops/desktops with a working camera & microphone and Chrome or Firefox browsers can be used to complete the exam. Please note, iPads are not compatible with the ExamMonitor software and may not be used for this exam.

No scratch paper is allowed during the exam – but I have enabled the digital notepad feature within Examplify, so you can use that if that helps. Also, just a reminder that using electronic devices (phones, tablets, smart watches, headphones) is not allowed while taking the exam.

If you experience any anomalies while taking the exam (examples include barking dogs, interruption by a family member, etc.) please email me at kkrafts@umn.edu after completing the exam to let me know.

Here’s a quick troubleshooting guide for Examplify for your reference.

Grading

After you take the exam, you will immediately receive your raw score. Final scores will be posted to your ExamSoft Student Portal and Canvas after I’ve reviewed the exam metrics. I plan to do that on Friday morning.

Finally…

If you have any questions about the exam please feel free to email me any time tomorrow. I’ll be checking my email frequently so I will be able to respond quickly.
