<h2>Protein BUILDER</h2>
<p>The protein builder allows you string together the building blocks of proteins, amino acids, and see how that string will form into a structure. You are presented with a goal protein shape, and your task is to try to re-create it. In the example below, the shape that you are asked to form is a simple line.&nbsp;</p>

Then, adjust the sliders to the baseline (default) setting shown below.</p><p>Baseline setting of sliders:</p><ul><li>Peak to peak voltage: \(v_\mathrm{IN}=3~\mathrm{V}\),</li><li>Frequency: \(f = 1000~\mathrm{Hz}\),</li><li>Supply voltage: \(V_\mathrm{S}=1.6~\mathrm{V}\),</li><li>Input bias voltage: \(V_\mathrm{BIAS}=2.5~\mathrm{V}\),</li><li>Pull-up resistor: \(R = 10~\mathrm{k}\Omega\),</li><li>MOSFET parameter: \(K=\frac{1~\mathrm{mA}}{\mathrm{V}^2}\),</li><li>MOSFET threshold voltage: \(V_\mathrm{T} = 1~\mathrm{V}\),</li><li>Vertical plot range: \(V_\mathrm{MAX} = 2~\mathrm{V}\).</li></ul><p>You should observe in the plot that with the baseline settings,
the amplifier produces a distorted sine wave signal for
\(v_{OUT}\). Next, go ahead and select one of the music signals as the input and
listen to each of \(v_{IN}\) and \(v_{OUT}\), and confirm for yourself that the
output sounds degraded at the chosen slider settings. You will notice
that the graph now plots the music signal waveforms. Think about the
reasons why the amplifier is producing a distorted output.</p><h2>Experiment 2: Linear regime</h2><p>We now study the amplifier's small signal
behavior. Select a sine wave as the input signal. To study the small
signal behavior, reduce the value of \(v_{IN}\) to 0.1V (peak-to-peak) by
using the \(v_{IN}\) slider. Keeping the rest of the parameters at their
baseline settings, derive an appropriate value of \(V_{BIAS}\) that will ensure
saturation region operation for the MOSFET for the 0.1V peak-to-peak swing
for \(v_{IN}\). Make sure to think about both positive and negative excursions
of the signals.</p><p>Next, use the \(V_{BIAS}\) slider to choose your computed value for \(V_{BIAS}\) and
see if the observed plot of \(v_{OUT}\) is more-or-less distortion free. If
your calculation was right, then the output will indeed be distortion free.</p><p>Next, select one of the music signals as the input and listen to each of
\(v_{IN}\) and \(v_{OUT}\), and confirm for yourself that the output sounds much
better than in Experiment 1. Also, based on sound volume, convince yourself that \(v_{OUT}\) is
an amplified version of \(v_{IN}\).</p><h2>Experiment 3: Your settings</h2><p>Now go ahead and experiment with various other settings while listening
to the music signal at \(v_{OUT}\). Observe the plots and listen to \(v_{OUT}\) as
you change, for example, the bias voltage \(V_{BIAS}\). You will notice that
the amplifier distorts the input signal when \(V_{BIAS}\) becomes too small, or
when it becomes too large. You can also experiment with various values of
\(v_{IN}\), \(R_{L}\), etc., and see how they affect the amplification and distortion.</p>

<div>
<p>While taking a course, you may be asked to write an essay or other written response. Follow the sequence above to see how assessment tools for written answers at edX work. &nbsp;In some cases, your peers grade your answer, in another scenario, a rather sophisticated AI like tool &ldquo;reads&rdquo; and provides you feedback. In every case, working with the assessment tools is easy and can help you showcase your best thinking. &nbsp;</p>

<p>This demo course is meant to show you the workflow of the edX essay grading options, not to make you write essays. If you don't want to compose your own essay, you can try these responses:</p>
<ol>
<li>Books that are offensive should not be taken off the shelf all together, but should be put in a section made for adult readers only. This way no children would see the book anyway. If an offensive book is in a school or any other place that the readers are children for the majority than it should be ok to take that book off of the shelf. All together it should be ok to remove an offensive book from a shelf but only if the book is offencive to the wrong audience.</li>
<li>No, i do not think that books, magizines, movies and music should be removed. However, I do think that the books, magizines, movies, and music should be monitred by age. The reason why is because younger children sould not be reading , listening, or watching material that is for adults or teenagers. They way these type of things can be monitred is by the child's library card. The card could have their name, age, grade, and date of birth. If there is a certain book, magizine, movie, and music that the child want a parent has to be there with them. The parent needs to show a form of identification so that the librian knows that the parent is of age. Teenagers should also be moniterd. Event though they are almost adults. Some parents not agree with some of the material. So, if their parents does not want them reading certain things their should be stickers on their cards. Even though there are plenty of opinions about what a persons child is reading , watching, or listening to I think there should be certain ways to watch what children are reading, watching or listening to.</li>
<li>In libraries, there should not be censorship on materials considering that it's an individual's decision to read what they prefer. There is no appropriate standard on what makes a book offensive to a group, so it should be undetermined as to what makes a book offensive. In a public library, many children, who the books are censored for, are with their parents. Parents should make an independent choice on what they can allow their children to read. Letting society ban a book simply for the use of inappropriate materials is ridiculous. If an author spent time creating a story, it should be appreciated, and should not put on a list of no-nos. If a certain person doesn't like a book's reputation, all they have to do is not read it. Even in school systems, librarians are there to guide kids to read good books. If a child wants to read an inappropriate book, the librarian will most likely discourage him or her not to read it. In my experience, I wanted to read a book that my mother suggested to me, but as I went to the school library it turned out to be a censored book. Some parents believe children should be ignorant about offensive things written in books, but honestly many of the same ideas are exploited to them everyday on television and internet. So trying to shield your child from the bad things may be a great thing, but the efforts are usually failed attempts. It also never occurs to the people censoring the books, that some people can't afford to buy the books they want to read. The libraries, for some, are the main means for getting books. To conclude there is very little reason to ban a book from the shelves. Many of the books banned have important lessons that can be obtained through reading it. If a person doesn't like a book, the simplest thing to do is not to pick it up.</li>

<h2>Self-Assessed Essay</h2>
<p>In one of the most straight-forward assessment mechanisms, you are given an opportunity to answer a question, and are then asked to assess your own performance based on an instructor-provided rubric or rule. Writing and assessing your own answers allows you to develop high levels of reflection as you revisit your answers, discovering for yourself your strengths and weaknesses in a way that will make it easier to understand how to learn. You can use the example below to see how it works.&nbsp;</p>

<h2>Combined Open-Ended Assessment</h2>
<p>All of the options for open-ended grading can be combined in order to provide multiple ways of grading the same problem. &nbsp;The combination can even require that you pass a certain level on one phase of grading before continuing on to the next phase of getting feedback.</p>
<p>The example below has combined self-assessment, machine assessment, and peer assessment.&nbsp;</p>

<h2>Find Your Study Buddy</h2>
<p>Working with other students offline can help you get the most out of an edX course and even increase the likelihood you will successfully complete the course. So, your homework is to find a study buddy.</p>
<p>The <a href="http://www.meetup.com/edX-Communities/">edX Meetup Community</a> is a fantastic way to find study buddies in your area. Meetups make it easy for students to organize get-togethers or study sessions in coffee shops and cafes, libraries, or at local schools. If there isn&rsquo;t an edX Meetup Community in your area, you can easily start one up.</p>
<p>Here are some Meetup Communities near you:<br /> <iframe src="http://www.meetup.com/edX-Communities/embeds/closest_event_list?css=&amp;w=600&amp;bg=light" height="320" width="600" title="Communities Near You"></iframe> <br /> The course specific discussion forums are also a great place to find neighbors or even new friends to invite to a Meetup you are looking to organize or even a virtual Google Hangout. Make sure you also join the edX community on <a href="https://www.facebook.com/EdxOnline">Facebook</a>, <a href="https://plus.google.com/b/108235383044095082735/108235383044095082735">Google+</a> or <a href="http://vk.com/edxrussia">Vkontakte</a> and to share with friends your edX experience. You may even inspire a friend to join edX and enroll in the course with you.</p>

<h2>Peer-Graded Essay</h2>
<p>Lastly, your course might use peer-graded essay assignments. &nbsp;One of the best ways to learn is to be exposed to other people's responses to a question that you have already thought critically about. Reading incorrect responses will make you more aware of many of the subtleties in a question that you might have otherwise taken for granted. Reading correct responses allows you to see different perspectives on the same question. &nbsp;</p>
<p>In some courses, several of these essays tools are used together to really provide a great learning experience.&nbsp;</p>
<p>How does the peer-grading tool work? &nbsp;There are three steps:</p>
<ol>
<li>Answer the question. Write a response to the prompt to the best of your ability.</li>
<li>Contributing to the student community: grade other people's responses. You will be provided with a rubric by the instructor, and asked to evaluate how other people's responses compare to the rubric. You can participate in this grading workflow by clicking on the "Open Ended Panel" option on the top of the screen, or by using the "Peer Grading" panel on this page below your submission.</li>
<li>After you have graded other student responses, your response will be included in the pool of responses to be graded, and other students will provide you with feedback on how you have done.

<h2>ZOOMING DIAGRAMS</h2>
<p>Some edX classes use extremely large, extremely detailed graphics. To make it easier to understand we can offer two versions of those graphics, with the zoomed section showing when you click on the main view.</p>
<p>The example below is from <a href="https://www.edx.org/course/mit/7-00x/introduction-biology-secret-life/1014" target="_blank">7.00x: Introduction to Biology</a> and shows a subset of the biochemical reactions that cells carry out. </p>

<h2>&nbsp;OVERALL GRADE PERFORMANCE</h2>
<p style="margin-top: 0px; margin-right: 0px; margin-left: 0px; padding: 0px; border: 0px; outline: 0px; font-size: 16px; vertical-align: baseline; color: #4c4c4c;">The progress tab (selectable near the top of each page in your course) shows your performance. Click on it now, and you will see how you're doing in this demo course.</p>
<p style="margin-top: 0px; margin-right: 0px; margin-left: 0px; padding: 0px; border: 0px; outline: 0px; font-size: 16px; vertical-align: baseline; color: #4c4c4c;">The bar chart shows the overall percentage that you have earned on each assignment in the course, and how each of those assignments combine into your overall grade. Further down the page is a detailed breakdown of your score on every graded question in the class.&nbsp;</p>
<p><img alt="" src="/static/ProgressPage.png" /></p>

<p style="margin-right: 0px; margin-left: 0px; padding: 0px; border: 0px; outline: 0px; font-size: 16px; vertical-align: baseline; color: #4c4c4c;">You might notice that some of your assignments on the bar chart show an 'x'. The 'x's indicate the assignments that the edX system will NOT be counting toward your final grade, according to the course grading. The 'x's go to the assignments that you scored the lowest on. &nbsp;</p>
<p style="margin-right: 0px; margin-left: 0px; padding: 0px; border: 0px; outline: 0px; font-size: 16px; vertical-align: baseline; color: #4c4c4c;">Each course has its own percentage cutoff for a Certificate of Mastery. You can see where those cutoffs are by looking at the vertical description. In this demo, a "pass" is considered 60%. When you "pass" a live edX course, you will receive a certificate after the class has closed. Sorry - the demo course does not grant certificates!</p>
