Hello here is my idea of a workshop RPG for ender's game.Problem description:
Preparing students for final exams can be hard and challenging. Most of them are already motivated as final exam is a way of entering college. Recent changes in Serbia’s education defined standards for education for science subjects such as chemistry, physics, biology… However, most teachers still haven’t adopted new ways in their educational methods to help students fully prepare for what awaits them.
Ender’s game RPG can be use as fun way to discuss new ideas and test your students at same time. It also helps in motivating students. START
At start students are being introduced to a book written by Orson Scott. Teacher says a few words about book and author and then he announces that he will read a part of a book then ask a few questions. At one point he will organize his class in to groups who will compete at certain tasks.FIRST ENCOUNTER WITH CLASSPART 1Teacher reads a part of a book. Class is asked not to take any notes and to just listen. "Andrew, I suppose by now you're just absolutely sick of having that horrid monitor. Well, I have good news for you. That monitor is going to come out today. We're going to just take it right out, andit won't hurt a bit."Ender nodded. It was a lie, of course, that it wouldn't hurt a bit. But since adults always said it when it was going to hurt, he could count on that statement as an accurate prediction of the future. Sometimes lies were more dependable than the truth.The doctor was twisting something at the back of Ender's head. Suddenly a pain stabbed through him like a needle from his neck to his groin. Ender felt his back spasm, and his body arched violently backward; hi head struck the bed. He could feel his legs thrashing, and his hands were clenching each other, wringing each other so tightly that they ached.Teacher now gives assignments.
(For teachers: First set of question is based on correlation between physics and biology, this can be used in every class as all questions are based on school curriculum for physics)
In this section Ender had his monitor removed. Monitor is a device surgically insert in children and used to follow them and record everything they see and hear. In next few task we will concentrate on such, still imaginary at this time, object.TEACHER CAN CHANGE QUESTIONS AS THEY THINK IT WOULD BE MORE SUITABLE FOR CLASS. I have only given examples of few.Q1Suppose that we can look at signals going true human nerves as one-way electric current. This current is in form of signal with magnitude of 75mV. An electric current needed to be detected is in order of 10e-12 A. How much resistance can monitor have in order to achieve this current? Q2In order to work monitor has to have power source. In this case specially designed source is used and it has been labeled with following 0.5kAh 2V. If maximum current it use is 1E-3 A how many hour can it last before it need to be replaced? If Ender is six at present and monitor has been inserted at his birth will battery last or will it have to be replaced at some time?Q3Thru monitor has ability to record everything Ender see. On this chart (shown at board) we can see sensitivity of human eye to different wavelengths at night and at day. At what wavelength human eye is most sensitive at day? Bonus calculate the frequency of that wavelength.Q4To give Ender even less privacy monitor has ability to record everything he hears. Considering that human can hear from sounds from 20Hz to 20000 Hz (more or less) what is the minimum wavelength of sound monitor can record?BONUS (for those who like to discus ethics as well as science)
Now class can be free to discuss about ethics of using monitors. After they set their opinions explain to them that in this world humans are often attacked by other humans and monitor can be use to protect children. Read them the part right after Ender had his monitor removed.His monitor wasn't perched on his neck, hearing what heard and seeing what he saw. They could say what they liked. They might even hit him now-- no one could see anymore, and so no one would come to Ender's rescue. There were advantages to the monitor, and he would miss them. It was Stilson, of course. He wasn't bigger than most other kids, but he was bigger than Ender. And he had some others with him. He always did. "Hey, Third." Don't answer. Nothing to say. "Hey, Third, we're talkin to you, Third, hey bugger-lover, we're talkin to you." Can't think of anything to answer. Anything I say will make it worse. So will saying nothing."Hey, Third, hey, turd, you flunked out, huh? Thought you were better than us, but you lost your little birdie, Thirdie, got a bandaid on your neck." "Are you going to let me through?" Ender asked. "Are we going to let him through? Should we let him through?" They all laughed. "Sure we'll let you through. First we'll let your arm through, then your butt through, then maybe a piece of your knee." Discus with class now about using monitors. Explain to them that in this future world an alien race of insects attacked humans and now after many years people have changed society rules in other to create better soldiers. Ask if they knew any other way technology changed society.PART 2 This part is again based on same scenarios. Teacher reads a part of book and then asks a question based on that. (For teachers: this part is set on gravity and free fall. It will also be used to check how well did students understood First Newton’s law, as well how well do they read charts) In this part we will find that Ender is on his way to Battle school. Him and other boys are currently on space shuttle waiting for launch…The other boys were belted in place, those who hadn't done as Ender did. Then they waited for an hour while a TV at the front of the shuttle introduced them to shuttle flight, the history of space flight, and their possible future with the great starships of the IF. Very boring stuff. Ender had seen such films before. Except that he had not been belted into a seat inside the shuttle. Hanging upside down from the belly of Earth. The launch wasn't bad. A little scary. Some jolting, a few moments of panic that this might be the first failed launch in the history of the shuttle. The movies hadn't made it plain how much violence you could experience, lying on your back in a soft chair. Then it was over, and he really was hanging by the straps, no gravity anywhere.
Q1When launching a spaceship in order to get speed shuttle will accelerate with rate of 10m/s2 . During the lunch will mass of Ender be
- Twice as normal
- None of the above
Mass has not changed but weight (amount of force he is pushing his seat) did. How did weight changed
- Twice as normal
- None of the above
"Most of you are going to ice out. Get used to that, little boys. Most of you are going to end up in Combat School, because you don't have the brains to handle deep-space piloting. Most of you aren't worth the price of bringing you up here to Battle School because you don't have what it takes. Some of you might make it. Some of you might be wotth something to humanity. But don't bet on it. I'm betting on only one." Suddenly Graff did a backflip and caught the ladder with his hands, then swung his feet away from the ladder. Doing a handstand, if the floor was down. Dangling by his hands, if the floor was up. Hand over hand he swung himself back along the aisle to his seat. "Looks like you've got it made here," whispered the boy next to him. Ender shook his head. "Oh, won't even talk to me?" the boy said. "I didn't ask him to say that stuff," Ender whispered. He felt a sharp pain on the top of his head. Then again. Some giggles from behind him. The boy in the next seat back must have unfastened his straps. Again a blow to the head. Go away, Ender thought. I didn't do anything to you.Again a blow to the head. Laughter from the boys. Didn't Graff see this? Wasn't he going to stop it? Another blow. Harder. It really hurt. Where was Graff? Then it became clear. Graff had deliberately caused it. It was worse than the abuse in the shows. When the sergeant picked on you, the others liked you better. But when the officer prefers you, the others hate you. "Hey, fart-eater," came the whisper from behind him. He was hit in the head again. "Do you like this? Hey, super-brain, this is fun?" Another blow, this one so hard that Ender cried out softly with the pain.
While being atacked by other students Ender had to defend himself. At one point he grabed a boy who was about to hit him and trow him with all force. Since there was no gravity boy flew with high sped and broke his arm. Next couple of question we will use to duscuss a non weight state.
While on Earth gravity surround us. We are used to it. However, people do want to feel weightless state. Imagine we are standing in giant elevator. In which way and by how much would he need to accelerate in order for us to feel weightless state
In Q4 we had not very safe way to experience zero gravity. Here is a safer. Now imagine a plane who orbiting around Earth at 10km. How fast does it have to go in order for us to feel zero gravity?
It would be cool to have such a fast plane, but for now we have to use something called parabolic flights. Here are some videos of what happens in such a plane, and here is trajectory of one plain. Can you explain how does parabolic flights work?
Now we are off to space. However, gravity is still following us, weaker yes but not at zero. Given mass of Earth, her radius and gravitational constant can you calculate free fall acceleration at height equivalent to Earth’s radius?
Suppose alien race leave on planet which is twice the size of earth and has 3 times bigger mass. Would gravity for them
- depends on their mass
Ender is only six but on Earth he can use his muscles to throw a rock weighting 5kg. If he uses same force on boy that attack him what acceleration will other boy have if he has a mass of 40kg.
Draw a graph describing change of speed if a rock is thrown with 10m/s in downward direction on Earth. Disregard air resistance
Draw a graph describing change of speed if a rock is thrown with 10m/s in any direction at zero gravity. Disregard air resistance.
In real life we cannot disregard air resistance. Which of this graph describes speed over time of a ball falling on earth?
(teacher has to prepare this in advance)
If we were to consider air resistance in zero gravity would terminal velocity of a ball (speed after very long time) be greater in zero gravity or on Earth? Which of this graph describes speed over time of a ball falling in zero gravity?PART 3
Same as before teacher reads from a book. He has to explain that now we are watching Ender as he is trained to be a soldier in specially designed arena with zero gravity.
Ender is now training to be a soldier. We will now listen about two of his newly discovered things. Ender took his pistol and demonstrated what he had learned about the two thumb buttons. "What does it do when you aim at a person?" asked Alai. "I don't know." "Why don't we find out?" Ender shook his head. "We might hurt somebody." "I meant why don't we shoot each other in the foot or something. I'm not Bernard, I never tortured cats for fun." "Oh." "It can't be too dangerous, or they wouldn't give these guns to kids." "We're soldiers now." "Shoot me in the foot." "No, you shoot me." "Let's shoot each other." They did. Immediately Ender felt the leg of the suit grow stiff, immobile at the knee and ankle joints. .Petra was waiting in the corridor that led to the battleroom. "Wait a minute," she said to Ender. "Rabbit Army just went in, and it takes a few minutes to change to the next battleroom." Ender sat down beside her. "There's more to the battleroom than just switching from one to the next," he said. "For instance, why is there gravity in the corridor outside the room, just before we go in?"
As we can see Ender’s light suit is made to show where he has been hit. All the battles between armies will be held at battleroom. Let’s talk about this room and about pistols use for this game.
As we all know gravity is important for human body to function normally. Many astronauts have been known to have medical issues after a long period at zero G. Imagine all the normal functions you would not be able to do with no gravity and describe them.
One way to create gravity is to rotate space ship. Imagine if space station, in which Ender is currently living, is about 2km in diameter. With what angular speed it should rotate to create acceleration equal to one G?
As we move to center of this space station does this artificially created gravity raises or decreases?
Now we shall take a look at Ender’s pistol. When part of light suit is hit it freezes. Suppose that pistol use light as a way to signalize this. If Ender shoot at his target 500m away , and as a result of hit bell rungs, how much time will pass until Ender hear the sound?
To freeze suit signal has to be of minimum intensity I. Once it leaves pistol signal has 2cm in dimeter and is spreading 1mm every 50 meters. Calculate maximum distance Ender can shoot at his target given that signal has intensity 2P at start. How much would distance change if intensity at start would be 4I?
Space shis is moving in zero gravity with constant speed. At point A space ship is turning on his rockets . Which of folowing trajectories is posible?PART 4
At this point teacher reads from book about ender becoming a comander of his own army.At the end of the week Dragon Army had fought seven battles in seven days. The score stood 7 wins and 0 losses. Ender had never had more losses than in the battle with Phoenix Army, and in two battles he had suffered not one soldier frozen or disabled. No one believed anymore that it was a fluke that put him first in the standings. He had beaten top armies by unheard-of margins. It was no longer possible for the other commanders to ignore him. A few of them sat with him at every meal, carefully trying to learn from him how he had defeated his most recent opponents. He told them freely, confident that few of them would know how to train their soldiers and their toon leaders to duplicate what his could do. And while Ender talked with a few commanders, much larger groups gathered around the opponents Ender had defeated, trying to find out how Ender might be beaten. There were many who who hated him. Hated him for being young, for being excellent, for having made their victories look paltry and weak
Now teacher divides hiss class in to 4 to 5 studnets army. number of armies depends form siye of class. it should ne boticed here that when working in pairs it has been proven that best practice is to team up more advance studnets with less advanced one. That way learning expirience has highest eficiency. EACH ARMY MEMBER HAS A NUMBER FROM 1 to 5.
Teacher explains to them that now each army has a homwork. Comanders have to give task to their soldiers to create as much questions as possible. All question have to be from class program, and in form of test questions. In next seasion armies will be set to pairs and compete with thees rules.
1. First army asks a question. memebers of opiste team answer in order from 1 to 5
2. Person who was asked has a right to consulate with his teammates and then answers. LEader of a team has a right to choose to answer a question himself and save his team member but before consultations.
3. If answer is corect team wins 2 points, if consulted only 1.
4. If team answers wrongly first army has to explain answer . In case that they fail to do so first army looses 2 points.
5. Proces is repeated for second army after which round is over.
6. Rounds are reapting untill by the end of round one team has 10 points. in case both team have 10 points game is countinued untill one team by the end of round has one point more then oposite.
7. At each time team can call for teacher as judge.
8. Teacher can give one negative point to team if he judges that question was unfair or passes over class level (For example teams gives a problem from state championship in physics which is considered as faul play)SECOND ENCOUNTER WITH CLASS
Game is played. At this time teacher monitors and looks what parts of subjects his students did not understand... As a help teacher can provide to his students test from final exams, PISA, and one more of mz favorite books PEAR TEACHING by Eric Mazur
