Okay, so The next thing to do is You guys have proposed projects on the hacknet page some of them some of you have proposed a couple of projects So some of you might have come in right now with a couple of project ideas in mind So what we're going to do right now is if you have anything in mind just come in front and present it So that the others can understand what you guys want to walk on through the night and you probably can Tell them if that's going to be possible or come and talk it basically Yes, everything is possible So yeah, if you guys have any ideas in mind just come forward and talk about it Then after that we'll sort of take a break for tea and snacks During which we'll sort of team up and then after that we get into the hack night as such so You're not supposed to see that about your eyes So there you saw the proposed projects as you can see so Any of you here who have proposed a project over here Let's come forward and talk about it. Hello. I'm Dave jeet from the singet always technologies so My project is about this is a front-end for no sequel data stores and It's doing this hack night event. We're just going to create a simple very simple app which is which will have which will install the servers and you you basically Pick on the servers and get to know your databases whatever databases are there and then you can see your collections and Documents and I did that document and that's it. That's that's that's about it for this hack night, but eventually we might add more features into it like Introducing a local local host tunnel web tunnel basically just like how browser stackers It will allow you to it will allow us to host that project somewhere and we're going to open source it in the future once it's working and The good thing about the local host tunnel will be It will be hosted somewhere and anyone can connect it and you know use the create a current tunnel local host tunnel and use the underlying whatever no sequel data store that you have and connect with it and Basically manage your data. That's the whole That's the whole point of it Yep, thanks. Okay. Thanks anyone else. That's a project over here And you're a first page something come up it started is that yours? Okay, let's go So I Love yeah, so I'm close to Sincar and I'm a Ruby on this program not at all the Jays guys will not be You might not respect me much, but that's fine I Haven't done it before but I want to do note I'll be working on this I This is so there was this MO OC this online course on course era so it actually uses node and this is the project that they Ask you to do so I I will be doing this just to see how I can use node and how it is different from the stock rates thing that I usually do I want to see the difference That is what I'll be working on. It's all open source So that's it Anyone else you see a lot of projects over here who proposed all this calling names calling names Yeah, I mean they should know that Vishal Malu When do you raise your hand? I'm Vishal I'll be working on creating a RSS reader using node I am a big fan of RSS and I use it like every day, but Google leader Google decided to kill Google leader now. I'm using Fiddly, but I'm trying to make my something my of my own so if Fiddly decides to kill itself, I'll have something and It's a no-billie. Yeah Also, I think node.js is perfect for this because you need to query all the websites and pass their XML and I Also plan to use some no SQL database. So I can store like I will have the cash off all the So that's my plan about this project Let's go to the next one Is that you? So Have you ever prepared for? Have you ever listened to music while pairing? That's basically the idea. The idea is have a Radio that you can the whole team can upload the music And they can listen to the music at the same time. So that's basically the idea Who's next Manish Mishra Everyone shy today Yes, I'm I'm Manish Mishra from Sabha and I have proposed three projects. Basically. I'm very new to node.js I'm very eager to know whether Different different business use cases can be handled by node.js or not All of them are just ideas So I will not be working might not be working on any of them But I would like to know whether those are possible in node.js or not I hope it is possible because we can if we can create the HTTP server then we can create it. You've already seen it Yeah, yeah, yeah, that is all like it here But I there are some two different project as well. I would like to go there Like sending the bulk SMS Yeah, that this one Yeah, we normally use the bulk SMS system we can send to multiple persons if somebody is registered to our system and We want to create a small system within in just a small period of time. Is it possible by using that node.js? Sorry As of now we I am not able to access to the API. There are some public API But is there any library or something like that available in node.js so that this type of system can be created or For creating this we need to create a separate library Where the API is sent SMS is then obviously it's very possible Okay, you're planning on sending SMS directly from a model or something Okay One of the problems with node is that you need to make Now it's fairly I would say mature in that sense But if there's no direct way to connect to whatever device you want to send SMS Okay If that's the case then totally easy So we're gonna like Bluetooth pair to a phone and start sending SMSs to us also I don't think he has a specific device in mind I think he's just basically saying can I do this because this is a problem that he has somewhere Yeah Related to you are connected to more than me it's totally like Okay This one is related something showing the some sales related data or something with that is very Positioning global positions related data on the map. I have mentioned the two cases I think here that is if you want to show the different different customers with their addresses on the map for some company like In me sir if we will zoom out and we will get it back getting the mold and mold it up from the map Relative to those customers. So there's a one use case another one in the title I have mentioned that if we want to measure the speed of any driver of truck In transport industry, then and we want to just Kind of find fetch the reports out of them. Is it it? This is a very complex use case Which means is it possible using the road here? I I Because I am very I am not aware of the node. Yes, so I just wanted to know that whether these type of libraries Some kind of libraries are there so that we can just pull up that data and show it on you. I You know just without putting extra effort or much effort on it Is it possible that we should do it everything using the MongoDB and all Yes Big and big and back and we can use anything Just a basic web application Obviously, you can do it at least that aspect of it getting the GPS data There are some devices that can run a load server. I don't know if that's the best way of doing it And I Can be the node. Yes, library communicates with the view api your location Like if it's coming from a device then the device has to communicate with no one that's totally possible That can be coming to you This kind of information will be coming from that some kind of device is See I whenever I was just putting this this project I have just put it the idea that I'm not working on it So I was able to know that whether this kind of application can be done in node. Yes, or not As to whether it's That's what that's why I have just mentioned that I will not be working. I get these are just ideas Which I would like to know the answer for them Thank you Who was next? Hi, I'm Tushar. I would like to propose a small To Do it your to send to it, which will be seen maximum such as it will be Calculated based upon your followers when they are active the most When they do it a graph will be generated so that you you would know when to tweet It would be helpful for marketing I will be just calculating based upon their previous Slender's next Hello guys, my name is really Earlier I worked on a POC It's a Twitter clone that I wrote using node express and mongo It was really basic. I mean you could just tweet and had comments follow users and Favorite a tweet, but it wasn't like full-fest So I want to add some more features in it and probably fix some bugs So let's see how it goes It's it's upon get up so All right, so This project is something that so I what what I wanted to do was we've got the conference coming up in what week? Two weeks two weeks in Bangalore. Yes, and that's coming up in Bangalore and What I wanted to do was build something that we can use at the conference for Conference attendees that are sitting in the same auditorium So what I thought of was what if we could have all the participants communicate directly over this chat platform or whatever Which is really really simple to do is know it as you can see From the stuff that I demoed but have it be like location aware So it knows where you're sitting in the auditorium. So I have like a graphical representation of the auditorium and When you say something it's like a speech bubble that shows up on top of your head So you can have some context in terms of you know where that person is that's typing that out So it's not completely anonymous you can add stuff like you know, what is Twitter handle is and stuff like that, so you know who to follow and I Don't know how much time we'll have but if we do have the time then I'd love to have it also somehow stream the the slides and live stream video live stream video so you can kind of just sit over there and Watch the video watch the presentation deck and the comments that are happening from the community along with where they came from in the Yeah Already Yeah, that would be awesome and then add the at the metadata about like the auditorium stuff at the node level Yeah, that's cool. That's a good idea Yeah, so what I'm saying is that like you have a hash memory Right that'll keep that information about where you're sitting based on like who's logged in to the chance of a locally and Only those people will get shown on the thing. We probably have like a Exactly like that guy, you know go whack him, you know, that's what I want I wonder I want that kind of thing and maybe if they give us that Twitter handle then we can also pull their tweets in If they have like the the hashtag for js food and have those also show up on their head Because then it'll give it some context, right? Otherwise like pizza happening out in the dark. We really don't know about them All right, so that's my one proposal for Someone has had a Yeah, it's meant to solve a real-world problem that we're facing in a project right now So we've got a site that we want to annotate want to share notes with others We want to store what's in some back-end Toggle them public or private. I mean, let's say it's kind of a book Let's say it's one of the epics that you want to annotate and You know derive your own meaning from some of those lines So you want to add it it for yourself or for others and you have the ability to share them and Even to eat them going forward and share them on social networks We'll be happy if anybody wants to join. Thanks I guess that's it or is there anyone else who suddenly had an idea. Yes Last minute Guys, my name is Nitesh and When I was thinking what I had to do tonight, I come up with actually one of my friends was telling me this cool idea that Something like eBay when the people actually buy something buy it through money I said of you buying through money people can actually exchange stuff So I have a stuff someone else's has some other stuff you both can actually exchange I think this is the right time. I could actually build some sort of prototype or spike it out if anyone wants to Here with me Cool someone else Is that all? Okay. All right. So a couple of things about the I can't itself. So upstairs over there. We have I should be saying this We have mattresses over there If you guys want to take a nap when you're really tired or something Okay, and go over there and chill and we have an open pantry just behind the screen actually So you can have tea coffee snacks and stuff all through the day and juice and things are there inside the fridge If you want to have something to drink. So, yeah, let's break foot here right now and You guys They're open all night. Yes Yeah, it's a hack night. Come on. It should be obvious. So that let's break for the night I'm not the night for tea and For us as one of the mentors so he'll be around catch up with him and talk to him about your project ideas and stuff and Vishal is the other mentor. So make sure we get the most out of these two people and also one more person is on his way Rakesh pie, so he'll be crashing the party soon and also get all of them. So I'll probably announce when he comes back You also are a mentor Person Kiran Jalgata, cool. So let's break foot here right now. We'll catch up later then


I am Dr. Rashmi Singh, Assistant Professor, Department of Education, SS Khanna Girls City College, University of Arama, and this is my email ID. And today, the topic of my discussion is flipped classroom. This is a very relevant topic, very buzzword in the field of education and irrespective of any discipline, each teacher, educator and student is concerned with this very topic. Okay, so let's start the topic and as usual, I have explained my topic in Hindi so that it will be bilingual and so that both the languages, people of both the languages can understand it in both languages. I mean, both my students can understand Hindi and English, so both the students can get benefits from it. So, flipped classroom. Before we start, I wanted to come to the video on educational research, but the topic I got from this topic is in the pipeline and it is better because I will share the video on educational research from here. So, first of all, flipped classroom. So, flipped classroom, like this diagram is showing you, it will be understood from here that the concept of the classroom is that we have flipped the traditional clip, right? We have flipped it, which is our classroom, so which one we have flipped? We have flipped the traditional classroom. So, what was in the traditional classroom? It was like we were reading, we were reading, the teacher came today, the teacher came to the classroom, he gave the homework, daily and questions, due tomorrow. We were getting that, and the teacher said, stage on this stage. What is guide by the side? Guide on the side. And there is activity, group work, discussion, how it is happening, we try to understand it. Okay. First of all, let's start with the definition. I found it to be a very good definition. That's why I have quoted it here. And it will understand what is flipped classroom and what philosophy lies behind it. Which philosophy is working behind it? The flipped classroom is a pedagogical approach. First of all, this is a pedagogical approach. I mean, we are talking about reading, there is nothing new in it. In which, what is in it? Diet instruction moves from the group learning space to the individual learning space. What is done here? Our learning space was the group learning space. Where? In the classroom. The teacher was teaching content, some concept, some construct. Students and students were in the group. But, I mean, what was he doing? He was disseminating his information. Now, what is it? Instead of the group learning space, what is this? Individual learning space. Why? Because individualized learning is being talked about. Personalized learning is being talked about. So first, the group learning space is now in the individual learning space. And the resulting group space. And now, the group space, the individual group space that has been formed, has been transformed into a dynamic. First, the group learning space will be interactive. That is, you talk about the one-way and one-way two-way process of learning environment. How to study? Where? Where the educator guides students, where the teacher will guide the students. Why? What can they do? They apply concepts and engage creatively in the subject matter. So that the students who study can apply the subjects, can apply them, can apply them. Creatively, that is the way that they engage in the subject matter. And from where did we get this definition? From the flipped learning network, we got this definition from 2014. So, a lot of things have come out. Direct instruction is moving. From where? From the group learning space to the individual learning space. And the individual learning space is being transformed into our dynamic or interactive. Why is it being transformed? Why is it being made? So that the students can apply the concepts and the subject matter can be creatively engaged. Okay. Then, the history of this is very interesting. First of all, we need to know that there is no new concept in the flipped classes. For example, we feel that this is a very different thing that has come out of the world from somewhere else. It is not like that. All the educators who want, whose philosophy is that we don't want to tell the children more than just in the classes, we want to establish dialogues, we want to have some discussions, we want to have some learning, we want to have some things that people are involved in. Until today, they all follow the philosophy of the flipped classroom. Or, they all have set a background for the flipped classroom. Secondly, if we start from the old times, if we start from where we started studying the Socratic method, then we know that the Socratic method used to be mentioned. It is not written in this. The Socratic method used to mean that the method used to be called the dialogue method. In that time, how many years did it take? I don't know, I have no idea how many years it took to learn. Then it was discussed that we would have discussions in the classroom and dialogue. After that, there is realism. That is the experimental method. Learning by doing. The teacher has to be on the side and the learner has to take the main role. Then there is progressivism, pragmatism, reconstructionism, reconstructionism. Instead of the teacher, everyone is investing in the role of the learner. And all these philosophers had prepared a platform for the new flipped classroom on which it was kept. Secondly, what is mentioned here is that the name that is known for the flipped classroom is from Jonathan Berman and Aaron Sems. But they did not invent the flipped classroom. There are so many people who were talking about flipped classrooms that they became famous and if you search for the name of the game then you will not get this name. But there are so many people who have done this or were doing this or were doing this and their role is in its popularization. So first of all, I am talking about U.S.S.R.A. and then there is the classroom model in 1984. That means something is done that is usually used in the classroom rather than something else. Then there is a very famous article of Alice on King and they quote from stage on the stage to the guide on this site. That means they are not making us a sage who is teaching children from a high school but we have to be their guide side by side. That means the philosophy has changed. We are coming from the teacher center to the learner center. Then this article is published by the peer instruction and newsverse manual. We also have to pay attention that the peer learning has changed. Then there is Barbara and Virginia telling us about Glen, Platte, Michael, Trebley and inverted classroom in 2000. Then in the Khan Academy in 2004 everyone wanted to know about Khan Academy and it was started that they uploaded some videos on YouTube so that they could understand what is the problem and that's what we are talking about. Then Jonathan Bergman in 2012 when he got his flipped classroom from here he got his article called Flip Your Classroom Flip Your Classroom Why? Reach every student or every class in every day and every day if you want to discuss with your class then it says Flip Learning Gateway to Student Engagement in various other articles which has flipped learning or flipped classroom in its core. Okay. Now let's talk about characteristics. First let's talk about what is happening in traditional classes. We teach concepts after teaching but when it starts she teaches and what is happening in extremely difficult culture and with culture there we would be not willing What is the quality of ZPDR? When there is a more knowledgeable person with you, you learn better. So, what should we do in-tune with the Revised Blum Stationary, in-tune with the ZPDR model of the Zygotsky, in-tune with the Bluners? What should we do? We should discuss the time in the classroom. We should do the high-order thinking skills, we should practice it, we should get married again, we should get married again. So, how should we explain the content to the child? So, the content should be given prior to the class. Prior to the class, before starting the class, the child should be contented. Now that the technology is coming, it can be given from paper to paper, it can be sent to you daily. But now, what is it? Now, make content, make videos. Prior to the actual class, you have to manage it, send it, share it, and what is the student's responsibility? He will teach it. He will teach it, that is, he will do the work of knowledge and comprehension level alone. And he will do the application analysis with the Synthesis Evaluation Teacher or with the peer group. That is why it is said that the peer learning is so important here. So, it is not necessary that every Flip Class should go to Flip Learning. But if we want that in every Flip Class we should be able to learn, after learning, after learning, we should be able to learn like after doing FLIP, what is the flexible environment? That is, the child can be taught anywhere, whatever the matter is given first. Then, we have to change the culture. We have to study in the classroom, we have to talk about higher order things. When we are alone in the house, when we don't have anything, when we don't have anything, then we will develop a understanding from the content. We have to teach in the classroom or we have to follow that model. Actually, the content should be like this that we can discuss, that we can use in every content. So, we have to choose intentionally. Deliberately, we have to choose that content. Then, educator must be professional. He should have professional ethics. He should be skilled in 21st century skills. He should be skilled in technical skills. He should be skilled in technology. So, we have to do all this. So, this is the characteristic feature to flip. First of all, determine your technology as soon as you finish teaching that we have to use this technology. Then, finish teaching and create your videos. You will make videos and content. Then, be transparent with students and parents. So, we have to tell the students and parents what is our rationale, why we are doing all this. You are the one in that, you will study, you will study, you will check with the parents that you have to tell your students that you have to come in every condition.  Then, keep it up. If everyone wants, we will repeat this model. This is just Jeff Dunn 2014. Let me give you some steps. Recording, sharing, changing, grouping and regrouping. We can flip the glass. There are many advantages We have written some things here. Think about it yourself. Explore it yourself.  There are many other points. What is the advantage of this? Intune with the needs of digital. Children are digital, parents are digital, immigrants are digital. So, their needs are digital. They are technos. They like to study online. They like to share videos. We have different learning styles. We have multiple learning styles. We have multiple intelligences. We have audio, visual, music, many other things. So, these are suitable for many types of learners. Then, increase interaction time between teachers and students. If the teacher has no time in the classroom, he is reading the concept, and the story is over. Then, new class, new topic. So, here, interaction time is increasing. Then, main classroom practices are more transparent. Everyone knows that if they see what is the teacher's video, what is going on, they can see everything together. Ensure spear learning. When we are having a discussion, we are talking in a group. So, spear learning is a very important role. And it involves spear learning. So, we include spear learning so that they don't take care of it. So that they don't take care of it. So, we can give them time to read it. We can check that they are reading it. Not like this. There are many other things. And, spear learning is a no-out. If it is so hard, spear learning is a no-out. There are many challenges. After that, if they don't have online access, if they don't have students, then we can't reach the recorded videos. This is good, because you can use it to offline. Then, students can deny taking responsibility of their own learning. It is possible that students don't want to take initiative. They don't want to take responsibility of their own studies. Because they are used to it. So, we don't want to read it. We don't want to take responsibility. We don't want to read it. These are very big challenges. Then, teachers must have technical skills. That's why you can do all this work. Institution may not have resources. You can say that we don't have any kind of education or education. We don't have infrastructure. Then, only cognitive domain is emphasized. There is not much to talk about psychomotor and refractive domain. We are only investing in cognitive domain. This is a big challenge. Then, sitting around classrooms creates hindrances. Generally, in our classrooms, seats are fixed. Then, we have a lot of group work. We have a lot of discussion about this. This is a big hindrance. Then, students do not have such intrinsic motivation. The motivation they have is that they have to prepare for every class. They don't have that much motivation. Then, it will be time taking. For both students, as well as teachers. Students have to prepare for time taking. Teachers have to prepare for time taking. But, there is no time taking. Then, the solution is that no one can find a solution. The teacher must explain the concept and rationale of the class in advance to students and parents so that they can study and support their parents to study. Then, videos must be short and interactive so that we can learn their interests. To online resources, institutions must upgrade themselves better Wi-Fi facilities should be there and there must be proper training to students and teachers so that they will be techno-savvy. Okay? Okay? If we come to its conclusion, this is a traditional film. Teacher Instructs lesson at home. Videos, podcasts, books can be a website. Additionally, teacher instructs or students follow guided instruction. Teacher gives assessment and students homework. Students work in class. Deeper understanding of concepts, applications and directions to content are made and students receive support as needed. Okay? Thank you. It's all from my side and I hope that the concept of Flip Classroom seems interesting to you and you all have a better understanding of it. Done from my side. Thank you. Thank you all.


We're now going to do a titration. A titration is a process that a chemist uses to determine the concentration of a solution. And the reason we do that is sometimes when you would think that if we weigh out a substance and find out how many moles of that and putting in our volumetric, we would know exactly the concentration. Some compounds are very hygroscopic and they'll absorb moisture from the air. For example, sodium hydroxide is very hygroscopic. When we take a sample out of a closed container, it's a nice solid tablet. But when we put it on the balance and wait a few minutes, it's going to absorb moisture from the air and thereby changing the mass. So our mass is not going to be a true mass. So in cases like that, what we have to do is we have to take a known concentration. In this case, we know the concentration of the hydrochloric acid because we can measure it exactly. And we're going to use that to standardize the solution that I made. Now, I think I measured out what I thought was a 1.0 molar solution. So what we're going to do is decide is that 0.9 or 1.01 and get this to three significant figures and get the exact concentration of our sodium hydroxide. To do that, we're going to use a burette. This is a burette. You can see that it's calibrated. This burette holds 50 milliliters.  So if it's parallel with the glass, it's open. If it's perpendicular, it's closed. If I want to do just a small drop wise, I can turn the knob here. Okay, so I'm going to close this and I'm going to put our sodium hydroxide that we want to standardize in the burette. So I'm going to pour this just a little bit above the zero mark. But since I'm not sure how clean my burette is, I'm going to rinse that burette with a little bit of the sodium hydroxide just to make sure that if there was any acid in here before, I'll neutralize it and then I'll just waste it. So this way I make sure that my burette is clean and has excess sodium hydroxide if anything in here. Okay, so I'm going to close it at this point and then I'm going to refill it. What you'll notice is that it's closed here so that there's air in this part right here.  And then I'm going to look at the top and I'm going to use a burette reading card. It's just a card with a piece of tape on it that gives me a reference so that when I look at this, I can see exactly the volume. You can see I'm above zero so now I'm going to let it out a little so it's on the zero mark. This is my waste container so I'll set that aside. In my Erlenmeyer flask, I'm going to use the hydrochloric acid that's standardized. Okay, and to get exactly 25 milliliters, this is very much like our volumetric flask. It's been calibrated to exactly 25 milliliters. This is four significant figures, 25.00. So we're going to fill it to that mark right there. What I'm going to do is pull a little bit more than I need. So I'm going to get it higher than the mark and then I'm going to let it out slightly. So I'm right at the meniscus. I'm going to take this out and then I'm going to take off the bulb and just let gravity work. Now these are factory calibrated. So when you let the solution out of a volumetric pipette, there will be a little drop lift on the end. You don't want to worry about that because the calibration includes just the amount that leaves the pipette. So we'll wipe off that drop. Now we have our 25 milliliters of hydrochloric acid in our Erlenmeyer. Now since we're using two clear solutions, we need to have something that will tell us when we have reached the end point. So I'm using phenethylene and in an acid solution phenethylene is clear. But in a basic solution, phenethylene is going to turn pink. So what we know is that we know exactly how much hydrochloric acid we have and we're going to add exactly that same molar concentration and when it turns pink, we'll know we've gone one drop too far. OK, so I'm going to adjust this so that the drops are going to go definitely into my Erlenmeyer and they're not going to splash out. I'm setting this whole thing on a stirring hot plate so I have a magnetic stir bar that's going to help me keep everything stirred. And now we're going to gradually add you see that pink color that comes right away and then it disappears. So we can keep adding as long as that pink color is there. And since I know that we have a one molar solution and we had 25 milliliters, I know it's going to take about 25 milliliters of my sodium hydroxide. Can you see that pink color? But it goes away very quickly when it begins to stay. Then we're going to slow down the rate at which we're dropping. You see, we're almost there. So I'm going to just try to do drop drop wise. If I think I'm almost there and I want to just add a half a drop, I can take water and just rinse off that end. And that last drop will fall on this. I think we have reached our end point. So at this point, what we know is we have equal moles of the sodium hydroxide and the hydrochloric acid. So we want to read our volume. Our volume is twenty two, you know, twenty one point five milliliters. OK, so now you do the calculations.
