The numbers listed as "Historic" are for all of the sections I have taught over the years. The "Current Term" numbers are for your section.

Now that you've taken an examination, it is very important to appreciate how much examinations affect your Total Current Score and all of your other Summary & Forecast numbers. This is because examinations are worth more than any other type of assignment, so your Summary & Forecast numbers will change more (either upwardly or downwardly) in response to examinations compared to anything else. The Summary & Forecast numbers are designed to let you know whether you'll be able to make it through this difficult course, so please have a careful look at all of those numbers (explained on the Summary & Forecast page of Canvas). If you see only zeroes, that's because you have ignored my messages about needing to submit the Rules Consent Form.

My neighborhood is experiencing intermittent Cox outages. I'm posting this during a period of connectivity, but I don't know how long my connectivity will last. If you have contacted me, and I have not responded, please realize that I am temporarily unable to receive email or grade online items. Thanks for your patience.

23 January 2024 C.E.

Notice that I have made a new link (LS Assessment) available under the Sources of Points section of the Canvas menu. It will be available only until 28 January, so be sure to have a look soon.

19 January 2024 C.E.

The question involving Metric System Problem Set 3 (in the Metric System Laboratory Activity) was eliminated on the morning of 19 January. Nevertheless, it could still show up for you (in which case the link will say that the file is not available). Please just ignore that question (if you see it). Thanks.

Now that you've gotten through the first day of the course, you've had a look around, and you've completed the First-Day Attendance assignment (to assure that you remain enrolled), it's time to settle in and learn biology. When you look at the Canvas navigation menu, you'll notice the section called Sources of Points. These are the categories of assignments. The weighting of those categories (how much they are worth) is indicated in the Course Syllabus, which you should already have read on the Hoffman Site.

The Examinations are the assignments that are worth more than any other. They also are the most difficult of the assignment types. To prepare for Examinations, you must carefully review the Lectures (linked in the menu under Required Learning Resource). Please do not think of the eTextbook (on the Connect site) as being the primary way of studying for the Examinations. All of the information for the Examinations comes directly from my recorded lectures, so the Lectures are the way to prepare for Examinations. It takes quite a bit of time to review the Lectures, so you must budget your time and spread out the studying for each unit's Examination. It is not posible to squeeze the preparation for an Examination into a night or two before the Examination. Please don't fool yourself and think that it is possible. Have a carefull look at the Assignment Schedule, so you know when each Examination is scheduled, then set aside times throughout the week so you can review the lectures and take notes for study (just as you would in a face-to-face course).

Unlike the Examinations (and the Laboratory Practicum, which is also an examination), the other types of assignments are available to you to complete any time you like (before the due dates, of course).

Each Laboratory Activity is an interactive assignment with specific instructions built into the assignment. You should expect these to take quite a bit of time to complete, so you should have a look at each one well before it is due. You don't need to finish in one sitting, so have an early look to assess how much time you will need to budget to complete it before its due date. This is why you need to keep a very close eye on the Assignment Schedule throughout the term. Do not lose track of any due dates. Every point is precious in this demanding course, so you don't want to lose any points foolishly (for example, by not knowing something is due).

Each Laboratory Quiz corresponds to a Laboratory Activity. That's why you should never attempt a Laboratory Quiz before completing the corresponding Laboratory Activity. The Laboratory Activity provides you the information for doing well on the Laboratory Quiz, so complete them in the proper order (Activity first, then Quiz).

The Topic Quizzes require two sources of information for proper preparation: my Lectures, and the chapters in the Connect eTextbook. Have a look at the name of each Topic Quiz, and consult the Lecture and the Connect chapter that cover that topic. You may take each Topic Quiz up to three times, but be sure to complete them well ahead of the due date, so you can take advantage of the multiple attempts allowed.

The Connect Homework assignments are publisher-generated questions that come directly from chapters in the Connect eTextbook. For each chapter's assignment, you should review the chapter in the eTextbook first (before attempting the homework), then you should consult that chapter as you complete the assignment. If you are unsure of any question's answer, look up the information in the chapter before submitting your answer. This can drastically improve you scores. It takes more time, but it is definitely worth it. Doing a text search (of the eTextbook) for specific terms or concepts in the questions will allow you to work efficiently.

The only assignments that feature limited access are Examinations and the Laboratory Practicum. Each of those will be available only on a specific date (indicated on the Assignment Schedule). Also, those are the only assignments that are NOT open-book, which is why the Examinations and the Laboratory Practicum require the Lockdown Browser. This is why you should complete the Lockdown Practice as soon as possible (ideally today), so you can assure yourself that you have all of the technical requirements in place for the first Examination. All of the other types of assignments (Laboratory Activities, Laboratory Quizzes, Topic Quizzes, and Connect Homework) are open-book, and they are available continuously. Please take very seriously the need to properly budget your time throughout the term, so you can succeed in this important but demanding course.

Thanks for reading, and have an enjoyable and productive term.

Introductory Remarks

Welcome to BIO181. If you've never taken this course before, the most important thing you can do to help you succeed is to realize IMMEDIATELY what you are in for. BIO181 is a very demanding course that will require many hours outside of the classroom to learn the huge amount of information that will be presented. Please do yourself a favor and just believe me on this, regardless of how easy your other courses might have seemed.

Since BIO181 is going to consume so much of your time just to stay afloat, it is worth taking some time right now looking at the various items that are on this website. After the term starts, you will be very busy, and if by then you already know what's available here to help you, you'll be able to work as efficiently as possible.

Although this site and Canvas might not yet be complete at the time your are reading this, you should fully explore both sites to see what's there and to get a feel for how things are organized. Click on every menu item to explore the contents. This includes the Rules Consent Form, which is absolutely required. If you do not submit it, then you will receive no credit for your work, and you will not be able to see your total score.

You should also realize that checking the website FREQUENTLY is absolutely required. If you would like to receive automated email notifications of new announcements, then simply join the list.

Even if no announcements are posted for several days, you still need to check for new announcements, because announcements will be official (and therefore binding).

It's also important to be sure that you are enrolled in the correct course. BIO181 is for biology majors, whereas BIO156 (which I also teach and which is very similar to BIO156) is for allied health majors.

If I sound like I'm trying to scare you, that's because I'm trying to scare you. But I only want to scare you into believing me about how demanding this course will be, because I want you to succeed, and I want you to get a lot out of the course. I certainly don't want to imply that you cannot enjoy this course. It'll be a lot of work, but it's also a very good course, and I think you'll learn a lot and have some fun.

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 16 January. It will appear on this Announcements page, because this course will require you to use this website in addition to Canvas throughout the term.

On 16 January, visit this site to find the word, then go to Canvas to complete the quiz, which will appear as a link in the Course Navigation 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 (i.e., if you are not already registered), then you should immediately ensure that you are on the wait list. 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 ty.hoffman@estrellamountain.edu) and include your full name, your student ID, and the word revealed on 16 January). 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 Very Important Requirements:

  • I will be offering all of the lecture examinations through 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.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 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, books, devices, etc. that are prohibited during the examination. This recording must be convincing, and it must clearly and completely show the empty 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, step back, 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 during the examination, 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.
