 Good morning to all of you, I am Sundar as he said from Chemical Engineering Department. So this is an interface where you conduct courses and you interact with students. So we are going to tell you about how to use this, how to install the software is a publicly available software. So how to install it and configure it which most of you I presume are from Computer Science Department. So you will be taught in a later part of this workshop. So assuming that you have got the system already installed I am just going to tell you how you are going to teach a course using this interface. So now the lecture that I have I am going to give you is itself I mean I have uploaded as a content in this interface. So as I walk through the lecture you will also see how the interface looks. So this is the interface model interface which in which the course will be there. So just as the course has got its own contents I am just going to put my own contents of the stock in this course. So what is model? It is commonly called as one of the content management system, course management system or a learning management system, different terminologies are used. Now it actually stands for modular object oriented dynamic learning environment. So that is what it stands for. It is under the GNU public license it is a free software that is why it is one of the most widely used public domain softwares. Now there are about 50000 sites which are running model officially I mean they are declared that they are using model but there are many more which have like in a private environment like within our own institute we have several model sites which are not open to public. So there are several such sites the number of courses are about 27 lakhs currently and about there are 3 crore students who have registered for this worldwide ok. Our own institute then this is second most popular there is one more called as a blackboard or a web CT you might have heard. So that is a license and it is a very expensive piece of software and after that the market share belongs to model. So it is one of the widely used systems. Our own IIT has got this model website which you see here model.itb.ac.n which is a publicly accessible site although you need to have a user account. So there are some courses which are offered on just like the CEP course you have other courses which have been offered in model and which is which can be accessed from anywhere in the world. So it is and our plan is to probably increase this to most of other courses that IIT is offering. Now what is why do you use web management basically it is this whole environment lets you to completely manage the courses right from enrolment, payment of fees and that kind of administrative tasks up to conducting the course teaching the course conducting quizzes evaluating grading and so on it is a complete set up only thing which is not there is possibly giving a degree everything else is there. So and it is being object it is a object modular environment it is very highly scalable. So as you can see this number of users although that is a complete big average there are many sites which uses nearly about a lack users just one site which can serve to so many users. There is some university in UK which does that it is called open university and they use this. So that is the advantage and now let me just go through the interface and tell you. So just discuss the broad layout of this things what you just familiar with what are the things there then we will go into the details. So this is the broad layout you have standard three column format so you have some information which is related to the so this is I have logged in as a teacher for this course. So I see something which is related to administration if I log in as a student I would not see all these things and this is the main course the way it goes the course can be organized according to topics like this or according to the dates I mean this is the first week the second week and third week. So whatever you are delivering in the first week the contents will go here and second week and so on that way. So this is the main content of the course is the second the center column and in the right column you have related events latest news what is recent activities has some courses been uploaded as some new material that is come up or is there any quiz that is coming up that kind of things. So this is the basic page layout I have organized this talk in three levels that is you can use model at a very basic level. So it is very similar to the way your web has evolved so initially web just meant that you have you just post some information somebody reads it there is no interaction. So you can design this whole thing in a similar way so at you could have a beginner's level where there is just one way communication you just provide some information as a teacher students read it there is nothing more than that just instead of mailing the students the assignment copies or mailing them lecture notes you just put it up and they download it is just a one way communication. You can have a little more interaction between the students and what I call it as an intermediate two way communication where you have chat rooms like where like the regular chat rooms of Google or other places or you have discussion forums you somebody asks question and you answer it. And you can ask students to submit assignments like scanned reports or they type in something and submit. So either of this is possible so it is little more interaction in that sense or you can conduct surveys find out how the course is going of this and particularly difficulty you ask post questions and get a poll instant survey. So that I call it as an intermediate level and an advanced level is more where you actually grade online based on something like what is called as a question answer forum. So question answer forum is a forum where you can post a question and the students get to see that so students are going to answer it. Now when you post a question if a student A answers it the answer is not seen to other students. Other students cannot see the answer unless student B poses student B can see the answer what A has posted only after B has posted the his own answer or her own answer. So this kind of little bit complex interaction is there which allows you to grade the students also when the answer is out all the students who have posted the answer before only they can see not the others. So it allows you to grade little more fairly and the most important thing that I personally use is what is called as a quiz which is basically an online examination. You can conduct a quiz which is properly timed and you can allow different ways of questioning the testing the knowledge I will go through that the details later but I am just telling you that these are online quizzes just like many of this online quizzes that you have online examinations that you have you are able to grade it instantly. You know you already coded the answer in the program and as soon as they answer it they are instantly graded and the marks are accordingly assigned and there are more complicated things like wikis you can allow you can let the students organically develop a new content by collaboration among themselves and you can evaluate them. So this kind of little more complex interaction between the students and the teacher and finally there is what is called as a grade book that is all the activities that you have conducted the quizzes, question answer forums, workshops, wikis all where you have actually given them grades either automatically or by actually going through that just as you are going to correct papers you can actually read those submissions there and grade it. So all those grades can be finally you do a grade analysis you sub give them different weights for each of the categories, so quizzes is 10 percent, this is 20 percent and so on and that grade analysis then assigning grade letters all these things is quite automatic. So all this is possible at three different levels of interaction with the students. Now so at the beginners level a few little more details now, now you play a role most of the softwares if you have seen you allows you to play as a login as a user it allows you to play different roles. I might be a teacher of one student a one course, but I could be a student of another course or I could be a teaching assistant of another course. So as I login I assume a role for that course and that role is initially assigned by the teacher of the course. So once as an administrator what you do is first create courses and assign teachers. So once the teachers are into a course then the teachers can assign different people or different users what their roles are say five of them are teaching assistants hundred of them are students. So that is called as a taking a role and let me just run through how to add contents to the course. So now I am going to tell you how to add some important contents very difficult I mean it has I said that it is only when you start using it you will learn it better, but just that something will get in now. Now so this is the interface this is the role that I said as a teacher I can switch my role to any sub roles. A teacher is a super role and under that you could have a teaching assistant a non-editing teacher or a student. Teacher has got more permissions than non-editing teacher who has got more permissions than a student. A non-editing teacher is typically a teaching assistant who is able to grade marks or grade these things, but he cannot add new content he cannot he is non-editing in that sense. He is a teacher in the sense he is grading, but he is a teacher who is not able to add contents. So when I want to add anything to this then we just go to this turn editing on option and that gives me little more editing flexibilities all these are all editing icons and I can do different activities here. So to begin with let us start with one by one from the left this is the participants of the course. I want to add participants or I want to delete participants that is students to the course. So presently these many participants are there in this course I can get information about them what are the courses he or she is his email address. Suppose I want an unenrolled this person he is basically I am going to take him off the course. So that can be done here. Now down here there is the course administration this one is not seen by students. So this administration suppose I switch role to a student I can see what a student sees. So student simply sees the participants activities minimal things news and this he cannot see anything more in the administration. He can see his own grades or he can unroll he can unenroll herself or himself from the course. So I go to my normal role here. So as a teacher I am able to change the settings of the course. So the course settings includes the details of the course. So this is the name of the course a brief description which will appear in the like this. So this is the description. So this is a list of courses that are conducted in this site. So this gives the description of the course. And then I can say what how do I want to arrange my topics the main the central content how do I want to arrange it. I can arrange it in weekly format week 1 week 2 week 3 and week 4 or I can arrange in topics format that is I do not have any particular week based but chapter wise. Suppose you are delivering a whole course each chapter would be one topic something like that sort. Then I say course start date some all these options which you can read yourself. So it is not very difficult. This is by enlarge the important thing till when from when you can start the enrollment when you can end the enrollment and some this is just basically the rough things of the course. These are usually created when you do it as an administrator of the Moodle site. So when you create it these things will be taken by default but then after you assign teachers teachers will be able to change small things in this. So that is about the settings. Now you are a teacher of this course it is been assigned to you by the administrator of the site. And then what you do is so you will have this one as blank there is nothing actually. So you have to first assign roles. Usually you can in IIT Bombay as soon as a student registers with our academic office they are automatically enrolled here. So in your cases you might have to set up those things or some way of linking this with the LDAP and things like that. So there are different roles now. Now I want to assign roles. So presently this course has got one teacher and 33 students. Now suppose I want to add more teachers to the course. So this is a list of students which are here on users which are in this site and I can add them as teachers. So I just search for him and I am just adding his him to be a teacher of this course. He is a teacher now. So I have two teachers now. So that similarly you can do with the students. So from a list of students you add students or delete students. So that is about assigning roles to the course. So that forms the group of people who will be actually seeing the course. Now let us say I want to add contents to the course. So which is the main course that I am going to teach. So I go to this editing mode. So I get all these editing icons here to add contents. So basically there are in the main section this main section there are two types of contents. One is a resource and one is an activity. So you can add a resource or add an activity. So each of these boxes here is one topic or a one week. This is first week, this second week and so on or it could be topic one, topic two, topic three and so on. So each of these boxes you can add a resource or you can add an activity. A resource is either a simple web page. So you can use this to create your own web pages also. I mean so it is a much more general environment but a very simple thing you can actually create a simple web page which is plain viscidic editor or you can. So this is just a viscidic editor where you put in the contents of a web page. For example this whole, this is a simple web page which is a resource. The lecture that I am giving you now, Effective Learning Through Modules, the lecture I am giving you now is a simple web page. So I just went and added a web page. This is a web page, I added a web page through that. Now you can also add a link to a file. So if you have, typically if teachers have their notes in a doc file of PDF file and they do not want to again type it here. So in that case you just upload a file and just provide a link. Like for example I have put a PDF link here. So this says for example the course syllabus, the texts and so on or the course notes itself. So that forms the resource which is of a file type. It is a link to a file. So these are all resources. Now about activities, there are several activities. It takes quite while to actually familiarize with, but I will just tell you the important things that are commonly used. So activities I said could be quizzes, forum, discussion forum or it could be workshops, wikis and so on as you can see here. So chat, it could be a questionnaire which is like a survey. You also have separate survey modules and wiki and quiz. So these are all activities which lets you more complex level of interaction. One of the default activity which comes in all courses is called as a news forum. So these are all discussion forums where you interact with the students. News forum is a special discussion forum in which by default only the teacher is allowed to post a content. Only the teacher is allowed to post content. The student cannot post content there by default. You can of course change it. Now when you post content, it means that it is just a discussion forum. It goes to a mailing list. So it is basically all the students who are registered for the course automatically get that information. So I am going to, this is a, so I am going to this news forum and I say add a new topic. So this topic I have already added here course starts today. So if I say this, the demo course begins at such and such time. So when I say this and I say post it and immediately everybody will be mailed to all, it will be mailed to all the participants of the course. Teachers, non-editing teachers as well as students. Now this is a news forum where only the teacher can post but the students can reply to the post. They cannot initiate a post. They cannot initiate a thread but they can reply to a existing thread. So they can reply. So they have some questions they posted back and everybody else can see it. So that is a news forum. But we can also create a more complex thing in which the students are also allowed to initiate a new post and then you carry on discussions. So somebody asks a question. Everybody else is able to, it is just like asking a question in the class. Everybody else is able to see and the teacher replies the answer. Everybody else is able to see. So that is some name for this forum. You can call it a general, a standard forum from general use. And then you just give some, so you create a, you can create a new discussion topic yourself or the students are now able to post it here. So they just click on this and add a new topic and they can discuss. So that is a very simple level of interaction with the students. Now coming to the other activities, what is, there is difference between an assignment and a quiz. An assignment is different types. You can post a question and ask students to upload a file or you post a question and ask students to type the answer, which again you have to actually manually go and correct as though you are correcting papers. This is nothing, there is no automatic correction involved. In assignments, there is no automatic correction. You have to read it and grade it just as you do in normal paperwork. Or it could be an offline activity. For example, you are conducting a mid-semester examination, some like I have added here. You are conducting offline activity, you are conducting a classroom examination, but you want to incorporate the marks obtained there into a common interface, which is here. So you are conducting a course, which is partly online, partly offline. But you want to do the grading online. So what you do is you create a dummy activity called as an offline activity. And then, so this mid-sem marks, which I have written here is an offline activity. And I go and say, I look at the submitted assignments. Nobody has submitted right, because this is an exam which was conducted in classroom. But I have corrected the papers and I have got the marks. And I just come here and give the marks here like that. I just, each of them, I look at their marks offline and add it here. So this becomes grading an offline activity and incorporating those results in a common interface, online interface. So as soon as you upload this, students will be immediately able to see the answers. You do not have to type the whole thing again and post it on your notice board or so on. You do not have to post the marks like that. So everything is incorporated in this interface. Students can see only their own marks. Of course they cannot see the answer script, but they can see the marks. And that is integrated in your final course grade. So that is called as an offline activity. So that is different levels of assignments. Now the other very important thing is called a quiz. Quiz is also and quiz is basically an online examination. It is an online examination which allows you to test different ways. There are different questions that are possible. You can time the quiz. You can allow reattempts of the quiz and several things. It is one of the most useful things that I found in my own course. The way I do is weekly assignments are given as a quiz. So I have a set of problems. I ask the students to solve it every week. But I do not have any time limits. You can do n number of attempts. So you solve it and you get a wrong answer. You go back, correct your solution, come back and try it and you keep doing this till you get the correct answer. So this allows a learning process, particularly they learn on themselves how to get the correct answer. They know the final answer when they have got it right. Now this is particularly important when you want scalability. If a teacher is teaching his class of 100 and if he has to correct 100 assignments every week, it is going to be huge amount of time. Now this allows the student to correct it himself. If he knows it is a mistake, he submits it, he gets the right answer. So you can give a penalty for submitting twice or thrice, but you do not have to give penalty also. That is up to the teacher's subjective decisions. But the main point is that it allows you to automate most of the processes, most of the routine processes of assignments. Now I would like to spend about 10, 15 minutes on this activity of creating a quiz. What are the different kinds of questions that you can set up and I just run you through that. So quizzes, this is online exam that I said, can be of different types. You can try, as I said you can allow multiple attempts. So let us just probably just go through this. I have already created this quiz. So when you create a quiz, these are the questions that will last. So when does the quiz open? So quiz can, so this is an online examination. You can have it indefinitely or have a particular time frame in which you are, the students are allowed to take this quiz. So let us say I open the quiz at this time and I close the quiz at say 5 o'clock. And do you want to have a time limit for the quiz? That is also possible. So you have, the quiz begins at any time between these three hours, but you can take it only for half an hour time, things like that. And some things like how do you want the questions to display. The nice thing about this is that you have, if you have a good question bank, hundreds of questions, you can select a few questions from there and give different students different question paper, which is again good. If you have similar level of difficulty, but different students see different questions. This one is a very nice thing as I said. Students can attempt the quiz multiple number of times. You can allow them to submit it once and then submit it after some time also, if they made any mistake. And you can have a great penalty for second attempt or third attempt and so on. There is something called as building on the last attempt. So this allows more better learning. Building on the last attempt, suppose I have done 5 out of 10 questions right. Only I have got 5 wrong. So second attempt I can just do the last 5 right or otherwise I can, the second attempt I can, the teacher can decide I will present a totally new set of problems to him. So this is making little more tough, but you would ideally want the student to build on the previous attempt. So that is about building on the attempt. And there is a section about what the students see immediately after an attempt. So immediately after the attempt are they able to see their own responses? Can they see the scores? Whether they got it right or wrong? Can they see the correct answers? You typically do not want to see, you do not want the students to see the right answers till the quiz closes. And then for each question you have a feedback. So you can type, so with the question you also type answer and a feedback to that. You give a hint or you say it is good, bad, whatever, some kind of feedback we will go through that. So these are things which control that aspect. Now so once I have done this, now I have to, so this is about the quiz, this is quiz administration. Now I have to actually add quiz questions to this. So I go to the edit tab here. So the quiz has got update the quiz and several things about the quiz, details of the quiz. So general info is when the quiz opens, when does it close. And the results, after the students have taken the results will be summarized here. So general information like how many students have attempted, 79 students or the students is registered for the course. They have attempted 5, 36 times. This is typically about 4, 5 times, not 5 times, how much is it? 7, 8 times, each student has attempted to 8 times. So results I can take a look at the results. So this person has attempted it once and has got 18 marks. This person has attempted it several times, each time he is probably improving or I do not know what he is doing anyway. So this is the information regarding the results. So you yourself can preview how the quiz will look. So once you set up the quiz, this is how the quiz will look to a student. So there is a question, there is a figure and there is a place where I can write here, she can write the answer and so on. So this is how the quiz looks. So this I did in the first time. So it took, it is like solving here and typing it there, that is nothing much, that is not much. So once you have solved it on paper, it is just typing it here. So let me just run through a sample quiz. Let us say you have already got a good question bank. How to? So this is the questions in the quiz, this is the question bank. So I select questions from the question bank and put, drop it in the quiz. So there are a lot of question banks here, different courses and different categories. So let me say that I want, so under the topic statics I have so many questions. So I can choose these questions to appear in the quiz. So I am adding questions to the quiz. So these are the questions which will appear to the students. So once I have done this, I can preview how the quiz will look to the students. So this particular quiz has been set for 30 minutes. As soon as you start by 30 minutes, it will automatically close everything. Whatever has been, answers have been written, those answers will be taken. So this is how the student sees the question, question paper. So there is a box. So this is one kind of question where you have to, at least in chemical engineering, we have problems like it is a typical physics problem. We give a numerical question where you have to solve, putting the variables, substituting for the variables and get the final numerical value. So I code the solution in terms of a formula in the question paper, in the question. But the students, each of them sees a different data set. Somebody will say 10 meters, somebody will say 1 meter, 5 meters and so on. So the numerical, final numerical answer is different. So it just prevents one level of copying. But the formula is the same. People see a different data set. So one person will see 6.5 kilometers, other person will see something else and so on. So this is how you, so once it is 30 minutes. So at the end of then, they are going to save it, but without submitting. Saving means just whatever is written here is just a form saving, saving the form. And submitting means submitting the whole quiz. And submit all and finish is the final thing that they all have to click, so that there is actually submitting the paper and going away. So this will also happen if 30 minutes is already, if the window is open 30 minutes over, it will automatically submit and it will go. So this is the overall view. I will go through the details now. So now this, there was an existing question bank. And from the question bank, I have just taken some questions inside. Now how do you create this question bank to begin with? So no, no see I want the, which question will come first, which question will come second, like say like that. So that has gone up there. Air and furnace has gone up now. For crude oil well, I want that to be the first question or the second question. So that is the second question. So when I preview it, the crude oil well will be the second question, the order in which you want the questions to appear. If you want it to be in a particular order, you can make it random, but if you want it to appear in a particular order, like if there is a question and they are following that there are three questions. So then you do not want it to be random. So you want it to come in a particular order. You can set it as a random, which is controlled in the main interface. Main quiz interface, you say how the questions should appear, should they appear in random or the default ordered fashion. So now let me just run you through how to create a question bank. A question bank is there are different types of questions. Calculated question, description, essay, matching, embedded answers, multiple choice, short answer, numerical and so on. Now I will just run you through. Simple question, this one is a true or false. You give a statement, they click on the radio buttons, true or false or it could be multiple choice. So it is just a check box kind of type. Then it could be matching. So you have two columns A and B, you give few statements here, you have to match them A to B, B to C and so on. So these are all mostly, I mean the module is a very general environment. So suppose you are from the universities and you are setting up for that, you will see that these kind of questions are more used by humanities kind of subjects, where you test the understanding the way they do it, not analytical skills. So even for my own course, I use these kind of questions like matching, true or false, to understand the students understanding of this, to gauge the students understanding of the subject, more of a non analytical testing. Analytical testing is done by two methods, one is the numerical and calculated. Numerical means the answer is a number, fixed number, constant always. Everybody sees the same question and the answer is some 3.42 or something like that and everybody answer is 3.42 that is numerical. Calculated is, I give a general formula for the answer, each student sees a different question and therefore the answer is different. So that is, I have to give a formula for calculated question and I have to give a constant for a numerical question. So you see here, this is the question type. So 2 plus 2 equal to what? So this means it is a calculated question, this is a numerical question and this is a multiple choice. So I will just run you through one or two this. So the way I can create a question here. So I do this, I create a new calculated question. If I go do that, this is what I will get. What I am going to do is to actually edit an already existing question, which is same as creating a new question. So here, whatever this is the question that is, this is my question. It is all given in some formulas and the answer is finally here. Now coming back to this, how does the question look? So the question is, now is anybody not familiar with latech or anybody knows what latech is? So latech is a programming environment basically. It is a word processing environment, which allows you to write mathematical equations, complex mathematical and of course typical normal formatting. So it is just like an HTML much more earlier version of structured programming. So there are, I want to use some Greek symbols and mathematical symbols typically, which occurs in our engineering courses. So I use this double dollar sign, anything that comes under double dollar sign will appear as a symbol. So I can show it to you there, air density rho a is equal to something. So that is what air density rho a, this is in latech is equal to I have put it in curly brackets here. So anything that I put in curly bracket is a variable, which can take random values as assigned by the program. Now this rho a, when it is displayed to the student, it takes from my existing database of values and puts a value there. So a student says 1.39 here, another student says 2.5 or something like that and I go through that. There is another variable here rho g, rho g is equal to curly bracket rho g, curly bracket rho g is 0.58 random variable and the height of h meters is 35.4 here. I am just saying h meters here and that is replaced. Now I have set up a problem in terms of variables and I have to give a solution in terms of those variables. So this is this, rho a minus rho g into h is my solution, it is very simple. Then once you do this, you say this answer, this is the answer, correct answer formula. What is the random values are assigned by the program? Correspondent, this is written in PHP. So you can, this syntax here is a PHP syntax, whatever Mac PHP syntax you use, the same syntax will hold here. So now those random values are assigned here and the program also calculates what the random answer would be and what is the grade for this answer 100 percent. So there could be some instances where you want to say that question has got multiple answers depending on the way you have thought about it. If you get this answer right, I will give 50 percent marks. If you get this answer right, I get maybe 50 percent marks. So that is why you are given option of the grade for this correct answer. And since this is all numerical, you need to give some tolerance. People while calculating they will leave out some decimals. So you need to give some tolerance to what accuracy the answer can be right. So I would say that tolerance of, relative tolerance of 0.2 which is about 2 percent. So if the answer is between, I will show you that within 2 percent of the correct answer, then I accept it. But it should not be 10 percent away which is a bad work anyway. And the correct answer I want to show 3 significant digits. That is a typical thing we follow in engineering that you need, typical students have the practice of writing 10 digits after one this one that does not carry any meaning in actual thing. So you have to typically use only 2 to 3 digits that is all it carries. So after saying that I go to the next page and these are the 3 variables that I have used. So again this is now. So this is where I add the actual numbers to this. I need to add some meaningful number. I do not want my density of water to take some arbitrarily random values. I need to give some reasonable values of density of water and therefore the density of air and the height over which I am asking. I cannot ask it what is the pressure difference in 2 millimeter of gas. I do not want, I want in kilometers. So I, this is where the teacher is able to decide on what range of parameters, what range of values the parameters can take. Like for example the height, height I have said in kilometers. So I am saying that kilometers between 20 and 50 randomly distributed between 20 and 50 uniform distribution between 20 and 50. I can have a uniform or a log uniform distribution. Then density of gas, density of gas is typically less than 1 in kg per meter. So I am saying between 0.5 and 0.8. Then density of water, this is in 10 power 3 kg per, this is also gas, both are gas here. One is gas and one is air. So that is also less than 1. Now what I do, this is the range of values I have said. Then I want to generate some 20 sets of data. So I just say add 20, force regeneration and say add 20. So already I had 10 items, now there are 10. So these are all different sets of problems each student will see. Student will see height of 28.2, density of gas is 0.61, density of air is 1.03 and so on. So this is what the student, each student could see randomly. So the students will get when they are presented, they are presented with these choices. And this is the answer based on this formula, rho a minus rho g into H. So if you do this, you get 19.1 mm. Now 19.1 is I said I need only three digits of significant digits. So there is only three digits here. And the range allowed is 2 percent. So any answer between 18.7 and 19.4 is acceptable to me. So depending on the complexity, if there are more calculations involved, typically the error also will multiply and then you said to 2 percent, 3 percent, 4 percent and so on. But typically 2 to 3 percent is more than sufficient. So that is it. So then you save the changes. So this you created a question and you saved, you created a database for it and you saved it and now a question bank is ready. And there is those question banks, from that question bank you can add and drop it to this. So I say that I want to add this particular problem here and that is there here. And what is it? So within each question I can say what it, what is the difficulty level of a question. So typically what we do is, how much time it takes to solve a particular question, 10 minutes, 20 minutes, 30 minutes, that you give as a default grade for the question and those all will get added. So that way you can compare two different questions. So when you edit a question, you are allowed to say what is the grade for the question, 15 minutes, 15 marks. But 15 minutes is typically a good scale, the time that required to solve a problem, you keep it as a default grade for the question. So that you can compare different questions and set up the total time for the quiz. So if you set the total time with 6, 1 hour, you typically set questions for about 45 minutes. So then you say what the maximum grade is. So presently the maximum comes to 115. So all these things will be rescaled to 100 marks now. So this is all set up now, you have set up the quiz and you have set it to be open at say 2 hours from now. So students are then able to see the quiz, they attempt it. So you give a bigger window. Even the question, the quiz takes only 1 hour, but you give say 1 and half hours. Typically what happens is you have login problems, students coming late, but they are allowed to take only for 1 hour. From the time they start, they are allowed to take only for 1 hour, but the total window you are allowed about say 1 and half hours or whatever you decide. It is exactly a course webpage where you, it is very easy to add contents. Now teacher can easily put up the class notes, put up assignments for download and a news group. Because usually typically what happens is teachers start at this level, they start at the level of just posting some information as a course webpage. They typically have it in their own webpage, but this allows little more thing. You do not need to know HTML programming, you do not need to know how to link a file. All these things are automated. So it is just a course that is what when I said three different levels. The basic level is simple one way communication where it is a course webpage. You put all the information, which is a plain HTML page, but edited using a specific editor and a news group.
