We recommend not to start with Hedy before the students have achieved at least a 3rd grade reading level.\nStudents (and teachers!) don't need any programming experience before starting with Hedy." + - text: "Hedy is divided into levels, in which new commands are taught. Each level contains a variety of adventures to practice the newly learned commands.\nAs a teacher, you get to decide which adventures are available for your students. Will they be making a restaurant, a calculator or a haunted house this level? Within each level, the adventures are arranged from easiest to hardest.\nSo your students keep getting challenged. The adventures can be done by the students individually, or you can use them in a classical instruction.\n\nThe adventures also include a code example, to make sure the less digitally informed teachers are able to use Hedy too!\nOf course Hedy also caters to the creative teachers that love to make their own lessonplans and adventures!\n\nAfter programming all the adventures of a certain level, your students can test their knowledge in the quiz.\nYou can track your students' work and their progress on the class page." + title: How does Hedy work? + - title: Devices + text: "Hedy is web-based, which means it works on any device with a browser (Google Chrome, Firefox, Edge etc), so laptops, Chromebooks, tablets and even smartphones are suitable to use Hedy.\nThere's no need to download anything before working with Hedy, just go to the website and you're all set!" + - text: "All Hedy teachers, programmers and other fans are welcome to join our Discord server. This is the ideal place to chat about Hedy: we have channels where you can show your cool projects and lessons, channels to report bugs, and channels to chat with other teachers and with the Hedy team.\nHere you can find a video on how to join the Discord Community." + title: The Hedy Community + - text: "Organizations in the EU have to comply with the GDPR (General Data Protection Regulation) when processing personal data.\nBecause this is a complex issue for many schools, you can use all Hedy programming functionalities without sharing personal data.\nThe easiest way to do this is to use Hedy without creating accounts for the teacher and students. Without accounts, all functionality is available, with the exception of personalizing levels, saving students' programs and viewing their progress. That is limiting, but there are schools that use Hedy in that way.\n\nA second way is for a teacher to create an account with an email address without personal data, for example \"docent25@email.com\". Apart from an email address, which is only required to reset your password, you do not need to share any information when you create a teacher account.\nWith a teacher account, you can create anonymous accounts for students, e.g. rainbow-student1, rainbow-student2, etc (See 'Teaching preparations' for a detailed manual). This way you can use all functionality of Hedy, including saving progress, without sharing personal data of yourself or your students.\n\nIf the above is not sufficient for your context, we can sign a processing agreement for the processing of your personal data." + title: Hedy and the GDPR + title: Introduction +- key: tutorial + title: Tutorial + subsections: + - text: Do you want to follow the tutorial (again)?

In this class you can see the students' accounts and their programs and you could monitor their progress.\nThis video shows you how to quickly create a class in Hedy." + title: Creating a Class + - title: Duplicate a class + text: "Are you teaching multiple classes? Then you don't have to customize each class individually. Simply make a class, costumize the class (see \"Customize your Class\" to learn how) and then duplicate this class as many times as you want.\nYou can duplicate the class on the 'For Teachers' page. If you duplicate a class, all the class settings are duplicated as well. This means that all the levels and adventures you've mande unavailable for the first class will now be unavailable for the new class(es) as well.\nThe student accounts and second teacher accounts in your class will not be duplicated into the new class." + - title: Add a second teacher + text: "Are you not the only teacher that teaches your class? Then you can now add another teacher to the class. Go to the 'For teachers' page and click on the class. Then choose 'Invite a teacher' and fill in the username of your colleague.\nYour colleague will get an invitation on their account to join your class. They can see that invitation message by clicking on their username in the upper right corner of the screen and selecting 'My account'.\nOnce the other teacher accepts the invitation they can customize the class as well.\nTo remove a second teacher from your class, go to the class page and remove the second teacher. The teacher who's created the class cannot be removed." + - text: "You can customize your class and choose which adventures are available for your students. This way your students won't be overwhelmed by the amount of adventures and levels, and they can specifically focus on the adventures you'd like them to practice with.\nClick on your class on the for teachers page and choose 'customize class'. On this page you can select levels, set opening dates, unlock level thresholds and more.\n\n**Select and order adventures**\n\nIn this section you can select and order adventures. The pink tabs are adventures with new commands. The gray tabs are regular adventures. To rearrange the order of the adventures, you can drag the tabs. However, we do advise you to use the regular order of adventures as the Hedy team made sure the adventures go from easiest to hardest.\nIf you want to remove an adventure for your students, simply click the cross on the adventure's tab.\n\nIf you want to add adventures, for instance your own adventure or an adventure you accidentally removed, use this menu to add the adventure to your students' adventures. Simply click the adventure you want to add and it (re)appears in the line of adventures. To undo all your changes to the adventures, click 'Reset'.\n\n**Opening dates**\n\nWith this feature you can set opening dates for the levels. This way you can make a lesson plan before your course begins and not worry about opening new levels each week. In the image above the first level is opened directly, the second will open the 23th of september, and the 3rd level the week after. The other levels are closed.\nDon't want to set opening dates? No problem, just leave this section blank.\n\n**Unlock level thresholds**\n\nThis featue allows you to set a threshold for your students' quiz grade, before they can continue to the next level. For example, if you enter \"80\" your students have to score at least 80% on the quiz before they are allowed to go to the next level. If they haven't met the threshold, they are not allowed to continue and have to retake the quiz.\nDon't want to use the threshold? No worries, just keep this section blank.\n\n\n**Other settings**\n\nThere are some other setting that could be usefu to you aswell. Our first extra setting is 'Mandatory developer's mode'. In developers mode the students only see their input and output screens and the run button. The adventures are hidden and there are no cheatsheets available. This might come in handy in a test situation.\nIf this option is not selected the developer's mode is available for students too as a voluntary option.\n\nIf you want all your students to be visible in de class highscore, you can select the second option.\nWith all the other options you can choose to hide some functions or content for your students, this might help them focus more.\n\n**Save**\n\nDon't forget to save your changes when you're done customizing your class." + title: Customize your Class + - title: Student Accounts + text: "To add students to your class go to the class page by clicking in the class name on the 'for teachers' page. Then click 'add students'. There are 2 ways to let your students join your class: You can create accounts for them, or they could create their own accounts.\n\n**You create accounts for your students**\nThe easiest way to add students to your class is by creating an account for them. This can be done by clicking the 'create student accounts' button and filling in the usernames and passwords for them.\nThe students can login with the username and password that you chose. Afterwards, they can change their username or password if they'd like and they'll still remain in your class.\nThis video shows how to add students to your class in the quickest and easiest way.\n\n**Students make their own accounts**\nYour students can also go to the Hedy website and create their own accounts, just like you did. To get them into your class, they simply have to click the invite link.\nYou can find the invite link on the class page and send it to your students. Mind that your students have to be logged in to Hedy when they click the link, in order to make it work smoothly.\nYou can also manually invite a student to your class with the button 'Invite by username'." + - title: Setting preferred language + text: "When students create profiles they are supposed to choose a 'preferred language'. Hedy will always be loaded in this selected language.\nChanging this language can always be done later on by navigating to 'My account' and 'My personal settings' again.\n\n**For non-English speakers**\nNot only can you change the language of the adventures to your own language. You can also choose which language the keywords (for example 'print' or 'ask') should be in.\nThis way you can teach your students to code with English keywords, but you can also let them program in their own language. For example, Dutch students can use the command 'vraag' instead of 'ask'.\nIf a student wants to switch languages, they can click the keyword switcher. It will switch the keywords from English to the preferred language and back.\nFun fact! Students are allowed program in both English and their own language at the same time! So, if they have trouble remembering some keywords in English, but easily remember other ones they can use both at the same time.\n\n\n**Video**\nThis video show you how to set a preferred language and change the keywords to you preferred language as well." + - title: Storing programs + text: "When you are logged in, you'll see My programs next to your profile icon.\nThis option exists for your students too. In My programs you can find all the programs that you've worked on.\nBy default, programs will be saved to 'My programs' when you run the code, and every 10 seconds, under their default name\nand their level (for example: Story 5). If you want to store a program under a new name, just type the new name in the name bar.\nCurrently, only one program can be saved per level, per tab.\n\nYou (and your students) can also share programs using the share button next to program names.\nThese programs will be posted on our explore page, for everybody to see and use.\nIf you want to unshare your program, go to 'My programs' and click 'Unshare'.\n\nThe paper plane icon can be used to hand in programs to the teacher of a class. Programs that have been handed is will no longer be editable." + key: preparations + title: Teaching preparations +- subsections: + - text: "Hedy contains a lot of different levels that each teach a different new skill.

Our slides could help you with that." + - title: Let's get to work + text: "Each level contains different adventures that you can find in the pink tabs. The first pink tab explains the new commands in this level.\nThe following tabs are adventures that the students can try out and make their own.\nThe adventures are arranged from easiest to hardest, so we recommend to start on the left and your your way to the right.\nThe last tab 'what's next' gives a little teaser of what you'll learn in the next level. Of course, you can select the adventures you want your students to do for each level.\nThey don't always have to make every adventure. Every adventure contains an example code, that the students can try out with the green button.\nThe example code gets copied to the workfield, where the students can try out the code and adjust it to make it their own.\nStimulate your students to turn the example code into their own projects by adding their own ideas and making their own variation of the adventure." + - text: "To test whether your students have picked up all the new info in the level, you can let them take the quiz.\nThe quiz contains 10 multiple choice questions about the new concepts and command to that level.\nNot every level has a quiz yet, as we are still building the quizzes.\nSome levels also contain puzzles. Puzzles show the students a couple of line of code that the students have to put in the right order.\n\nThis video shows the quizzes and puzzles." + title: Quizzes and puzzles + - title: Evaluation + text: "Round up your lesson by having a brief evaluation. What did the students learn? Which hardships did they come across?\nHow did they learn from their mistakes?

This is called a variable. + error_code: ask what would you like to eat + solution_code: order {is} {ask} What would you like to eat + error_text: In this level students learn about variables. The ask command requires a variable as well, but students forget this. + title: Students forget that the ask command has changed + - example: + solution_code: "answer {is} {ask} Why doens't {echo} work anymore?!\n{print} answer" + solution_text: Use a variable instead. + error_text: For some students it might be frustrating to learn that the `{echo}` command doesn't work anymore. That's why it's very important to explain the advantages of using variables.

In level 4 this is solved with quotation marks. + error_text: In the example below the word 'name' is used as a variable, but also as a normal text. The output of this code will be 'Hi my Hedy is Hedy'. + error_code: "name {is} Hedy\n{print} Hi my name is name" + - example: + error_code: chosen door is ask Which door do you pick + solution_code: chosen_door {is} {ask} which door do you pick + solution_text: Add an underscore. + error_text: A variable should be named with one word. You could use an underscore to connect two words. That counts as one. + title: Students use long variable names containing two words. + - example: + solution_text: Always check whether the variable has the same name throughout the code.

You can create your own classes, lesson plans and follow how kids are doing.\n* You do not need to know a lot of programming if you begin, Hedy works step by step, also for you!\n* You can use Hedy in your native tongue because it has been translated into many other languages!\n* Every kid can programme!! Hedy is especially helpful for kids who have vision problems because it can read material aloud to you without the need for a mouse.\n* We are here to help, you can find us for example on [Discord](https://discord.gg/8yY7dEme9r) or you can [email-us](hello@hedy.org)." +- text: "Various teachers worldwide have expressed their passion for Hedy, as some have shared with us:\n\n*Incredibly inspiring! Super good way to make programming a lot more accessible for yourself, but also for students. Very fun to play with and a lot of potential to use with the students. I think it is a very nice tool! I believe this is a valuable way for children to start learning programming. Python and coding have always been very exciting, because the barrier to learning is very high. Now everything is a bit lower and it was explained that it can actually be very easy. I enjoyed seeing how Hedy tries to make programming as accessible as possible for users!*\nNetherlands: Mathematics teachers in training (secondary school)\n\n*Simple interface and good examples.* Teacher: 3rd - 6th grades (elementary)\n\n*Multilingual programming and just the gradual programming concept itself.* US: middle school, 6th-8th grade\n\n*The gradual nature of introducing programming.* Australia: High school\n\n*Continues automatically.* Netherlands: 2 HAVO-VWO\n\n*Both that the explanation can be in Dutch (and the code in English), and that it builds up with more and more possibilities.* Netherlands: Plus class group\n\n*But Hedy and its gradual levels...what an idea, I wanted to personally thank you for creating this. I cannot thank you enough. Also, I have never seen the level of engagement and enthusiasm of my students, as I have seen with Hedy. We have covered till level 5, and plan to spend one more week on it in classes and labs, before starting Python.* Pakistan\n\n*The 'realness' of programming, it resembles how it is in reality.* Netherlands: Plus class group 4 to 8\n\n*Step-by-step activities. Fun activities.* Netherlands: 1e All levels, 2e VWO/HAVO 2e VWO +, 3e HAVO 3e VWO\n\n*I really like Hedy very much and it is also nicely set up, which makes it good to use in primary school. Hedy's gradual approach works very well. The short explanation at the beginning of each level and the short example programs help to give the children a quick insight into what is new in the chosen level. The different assignments that the children can choose also work very well. You see the children choose assignments that appeal to them and they then get to work with them, through the levels. Hedy is great fun for children who are good at programming and want to get a taste of a real programming language. It is good preparation for secondary school as soon as more ICT education is given there.* Netherlands: Oegstgeest Montessori school\n\n*The construction is so good.* Netherlands: Lower secondary school HAVO-VWO\n\n*I can keep the pace of the class.* Netherlands: group 7 en 8\n\n![Felienne teaching kids](/images/teacherfeedback/Fkids1.JPG) *Felienne teaching kids*\n\n\n![Kids learning about Hedy](/images/teacherfeedback/Fkids2.JPG) *Kids learning about Hedy*" + title: Teachers about Hedy diff --git a/content/parsons/zun.yaml b/content/parsons/zun.yaml new file mode 100644 index 00000000000..f8f295a0ca4 --- /dev/null +++ b/content/parsons/zun.yaml @@ -0,0 +1,88 @@ +levels: + 4: + 2: + story: Create a lottery that lets you choose an extra prize that you might win. + code: "prizes {is} car, hamster, 1 million euros\nprize {is} {ask} 'What would you like to win?'\n{add} prize {to_list} prizes\n{print} 'You won a ' prizes {at} {random}" + 1: + story: "You are the newest Pokémon trainer from Pallet Town!\nMake a program that selects your first Pokémon.\nLet the program wait a second before revealing your first Pokémon." + code: "pokemons {is} Pikachu, Charmander, Bulbasaur, Squirtle\n{print} 'This is going to be your first Pokémon!'\n{sleep}\n{print} pokemons {at} {random}" + 5: + 2: + story: Create a maths game. + code: "{print} 'Solve this problem'\nanswer {is} {ask} '88 - 16 = ?'\n{if} answer {is} 72 {print} 'Correct!'\n{else} {print} 'Wrong!
