[BLANK_AUDIO] Hi, my name is Justin Johnsen. I'm an online course associate for Duke University. I'd like to guide you through a few of the features on our course site, for Marine Megafauna, an introduction to marine science and conservation. When you first log into the website, you'll be taken to the home page which contains announcements for the class on our bulletin board with the most recent posts at the top. Announcements are one of the primary ways for the instructor and the class staff to communicate information about the class to students. So be sure to check here for updates regularly. Also on the home page, is a list of recently released videos and quizzes as links. On your first time through the class website, I would recommend beginning at the start here page. On this page, you will find a brief description of the class website. The first section highlights the important information for students to know at the start of the course, including the syllabus, our class philosophy, the timing of due dates for assignments and our grading policy. The Course Core section contains the regular class materials that the students will use on a weekly basis. The supporting content section is a collection of optional reference materials and resources that students may find helpful, but is not required for successful completion of the course. Such as our class map, frequently asked questions page and bio's of the course staff. At the bottom of the Start Here page is the site map for our course. Let's use it now to open our Syllabus page. The syllabus contains a list of topics we're planning to discuss throughout the course, arranged by week. The Class Philosophy page shares ourvision of the course. And our expectations of student conduct within the course site. The Due Dates page provides some assistance with converting between the Eastern US time zone, where Duke University is located. And your own time zone, as well as lists the open and close dates for each assignment in our course. The grading policy lays out the important details about how the final grade for our course will be determined. Please make sure to review this page before taking any quizzes. Let's move on to the Video Lectures page. Video lectures contain the primary instructional content for this course. Lecture titles describe the topic for the video segment, followed by the duration of the video in parentheses. The streaming video player can be opened by clicking on the lecture title directly. Often, there will be a series of icons to the right of each lecture that will allow students to download slides from the lecture. A text version of the in video questions and subtitles, as well as the video itself. Additionally, there maybe links to supplemental contents provided by the instructor and staff; such as, external links to other internet content. The required reading page will contain all the papers from the PLoS One collection, that we will read as part of our course. Each one is a downloadable PDF document. The papers are arranged by the week when they will be discussed and mentioned in the quizzes. Students can access the quizzes in the appropriately titled quizzes page. Quizzes contain sections that correspond to the video lectures. Each quiz contains a blue button labeled attempt quiz, to start a quiz. A due date line will inform you when the quiz will no longer be offered for credit. Next to the due date line is a grey apply late days button, where you'll be able to extend the due date if you're short on time Below the due date is the hard deadline date. At which time the quiz will be completelyfinished. The effective score represents your current result for each individual quiz. And it will be updated with each new quiz attempt. A number of attempts tracker shows how many times you have submitted an attempt. And also the date of your last attempt, and the score from that attempt. Below these will be a gray button labeled to show previous attempts, which will allow you to review every attempt submitted for each quiz by clicking the blue hyperlink to the far right. Let's see what happens when we attempt a quiz. First, you arrive at a confirmation page, where you will see the title of the quiz you selected, the time limit, if any. And the current number of attempts you have made for this quiz, not including the one you are about to start. Click on the green start quiz now button to officially begin your quiz attempt. Once you are in the quiz, you'll find a scrolling page of questions with an honor code check box at the top and bottom. You will need to check this box each time before you can submit your attempt. Let's go back and see how you can apply late days to quizzes. [SOUND] The apply late days page will show you the number of days you currently have added to this quiz, the number of remaining late days you have available, as well as the due date and hard deadline for this quiz. You can change the number of late days from this quiz in the text box below. [SOUND] Notice how the late days applied, and the late days remaining values change after I click the apply button. Also, the due date has changed, extending the time when I can successfully attempt this quiz by two days. If you find that you've applied too many late days to a quiz.You can still change the number, even after the due date or hard deadline has passed. Just enter the new desired value in the text box. See how the late day is applied, and Late Days Remaining have changed again? But remember that this will always effect the due date, too. So if you use late days to include a late attempt Removing the late days will change the score of that attempt to zero. The writing assignments page has a short general description of the process and a list of all the pure assessments available for students to attempt or review. The blue go to assignment button to the right of each peer assessment, will take you to the specific instructions for the assignment. It can be viewed at any time while the writing assignment is available. The discussion forums are at the heart of the class experience. We have created a series of forums for students, some with additional subforum levels. Students can create new threads within a forum by selecting the start new thread button. If you experience problems with the course materials or discover technical issues you can post these in the Course Materials Errors Forum and the Technical Issues Forum respectively. Forum posts can be sorted several ways. And forum threads also track information about the number of points, posts, and views of each thread. Please take a moment after watching this video to find our welcome thread and introduce yourself to the rest of the class. On the additional reading sources page, you will find some information about our course facebook and twitter accounts. You will also find links to frequently asked questions page and the course corrections page. We also have a section about you, our students. Here you will find a class map where you can add a pin for your location in the world. The slider bar on the map will allow you to zoom in andout and the add button will let you enter your name and location. It's okay to use a pseudonym, perhaps even your Coursera user name. [BLANK_AUDIO] There are also pages here for the results from our pre-course survey. Histograms of quiz grades and various class facts. Each of these will be added to as we progress through the course. Finally, we have a page with some information about us, where you can learn some of our background. Thanks for listening to my quick tour of the class website and I hope you enjoy your class experience. See you out there. [BLANK_AUDIO]
