Two important points about withdrawal:

If you make the decision to withdraw from the course, you do not need to visit any campus office or submit any form. You need only inform me of your decision via email, and I will process the withdrawal.

If you finish the course (i.e., take the final examination), you will no longer have the option to withdraw, and you will receive a letter grade based on your total score, according to the grade levels defined in the course syllabus.

I'll be in the wilderness in northern Arizona from 09 September to 11 September, and my connectivity will be spotty, so responses from me to any messages you send might be delayed. I'll try to keep an eye on things as much as possible. Please keep in mind that technical problems should be addressed to the IT folks, so please do not wait on a response from me about computer problems, etc. For those concerns, submit a help ticket. Enjoy the weekend.

Unfortunately, very few of you have completed the Lockdown Practice. That means most of you are taking an unnecessary chance of having your upcoming examination not count. If that happens, you will not be allowed to redo the multiple-choice version, and you will be required to complete a short-answer version. To prevent that possibility, you should complete the Lockdown Practice as soon as you are able, then let me know via email that you have taken it. I can then tell you whether you are set up properly for the examination.

If you already completed the Lockdown Practice, you should have received a message from me via email about whether your video was acceptable.

I have added a link to the LS Assessment, which can earn you some points for this course. Please read the instructions as soon as possible, and remember to complete it by 4 September. I put the link near the top of the Canvas menu. Thanks for participating in the study.

Some of the assignments in this course require you to take photographs and insert those images into worksheets. If your camera does not automatically produce images in PNG format, then use the conversion site linked below to convert your images to PNG format. Just choose the appropriate document types from the dropdown menus on the site (one for "convert" (from), and one for "to"). Be sure to choose Image then PNG for the "to" format.

Thomas (the person in charge of the server on which the Hoffman site resides) has figured out why some students were not able to access the Hoffman Site. He will fix it today (23 August 2022 C.E.).

Welcome to the fully online version of BIO181 for the autumnal term of 2022. After reading the rest of this announcement very carefully, please go to Canvas and carefully review the entire Overview Video. Also, I highly recommend signing up for automated notices of announcements that will be posted here.

Since this is an online course, you will be required to demonstrate your attendance (for the first day only) by completing a quiz on Canvas that will ask you to enter a specific word. That word will appear on 22 August (the first day of the term). It will appear on this Announcements page, because this course will require you to use this website in addition to Canvas throughout the term. Therefore, you must demonstrate that you have accessed both websites.

On 22 August, visit this site to find the word, then go to Canvas to complete the quiz, which will appear as a link in the Canvas menu for this course's Canvas. The link will appear as "First-Day Attendance".

The quiz will be automatically graded, so you will be able to look at your grades on Canvas to verify that you have successfully submitted the quiz. If you fail to submit the First Day Attendance quiz, and if there is a wait list, then you will be withdrawn from the course.

If you are trying to get into this section, then you should immediately ensure that you are on the wait list by registering via the EMCC site. Do not wait until the first day of the term to do that; do it right now. Once you are on the wait list, you must also demonstrate your attendance the first day. However, you will not have Canvas access. Therefore, send me email (directly to and include your full name, your student ID, and the word revealed on 22 August). Only students on the wait list should demonstrate attendance by emailing me; all REGISTERED students must do so by submitting the Canvas quiz.

I will request that students on the wait list who have demonstrated attendance be added to the course, but the college will not allow me to exceed 24 students, so this can occur only if there are registered students who do not demonstrate attendance on the first day, and the order of names on the wait list will be used to determine the order of students to be added.

Some IMPORTANT points about examinations:

  • All of the lecture examinations must be completed on Canvas. However, to be eligible to take those online examinations, there are strict requirements that must be met, and you must convincingly demonstrate that you meet those requirements. Otherwise, you will be required to take the lecture examinations on campus in the testing center. Whether taken online or on campus, the lecture examinations will be entirely multiple-choice. However, see exceptions below.

  • To be eligible for online lecture examinations, you must adhere to all of the following:
    1. You must use a computer that is equipped with a webcam and is compatible with required lockdown browser software.
    2. You must download, install, and run the lockdown browser software.
    3. An iPad will work, but other mobile devices probably will not.
    4. A Chromebook MIGHT work. The Chromebook version of the lockdown browser software is in beta. Therefore, there is no guarantee that it will work. If all you have is a Chromebook, then you might be required to take in-person lecture examinations on campus. If this applies to you, please email me as soon as you know that.
    5. Prior to the start of each lecture examination, you will be required to make a video recording of your surroundings to demonstrate that you have no papers, book, devices, etc. that are prohibited during the examination. This recording must be convincing, and it must clearly and completely show the desk space in front of you. This will require you to lift up your computer (if the webcam is incorporated into the computer), turn it around, and point it downward to clearly demonstrate that the surface is free of materials. If it is not possible to move the camera in this way, then you must use a mirror to show the desk space.
    6. If the video is not sufficient, then your examination will not count, and you will be required to take an alternative version that will NOT feature any multiple-choice questions.
    7. Each examination will be timed, and you will be required to finish it in one sitting. If you leave your chair during the examination, or if you wear headphones or earbuds, then your examination will not count, and you will be required to take an alternative version that will NOT feature any multiple-choice questions.
  • I would really like this to go smoothly for everyone, which is why I have made a practice test called Lockdown Practice. You will find it on the Canvas site for this course. It is not worth any points, but it is required, and it will give you the peace of mind of knowing that you have the hardware requirements in place for the real examinations. Please complete the Lockdown Practice at your earliest convenience. Pretend that it is a real test, so take the time to make a careful recording of your surroundings. That way, I can review your practice recording and tell you whether a similar recording on each test day will be sufficient.
