@flores-yorkshireacademy said in Emitter with model:

My students are learning to code in 3D. They want to use the emitter as a sonar for an ROV; is this possible?

Hi Kathleen,

It is not clear what your students are trying to do. If you can share an example project, we can try to help modify it.

For a generic explanation, to make anything glow, it has to have emission colors. By default the models don’t have emission colors (they only have diffusion colors), so they won’t glow. However, we can update the models to add emission colors to them.

Note that the “update color” block requires you to specify an “area”, which can be up to 4 parts of the model, and the meaning of each area is different depending on the specific model (you will have to try them to find out). Here is more information on that block:

Introduction

 

To most people, quizzes are not fun: they can be too easy or too hard, and we may have to take them before we are ready. However, quizzes are one of the most effective tools for reinforcing what we have learned and identifying gaps in our understanding.

With XO, you can get quizzes that are much more fun: you can customize the theme of the quizzes and choose the difficulty level.

If you are a teacher, you can also use XO to generate quizzes for your entire class.

 
For an important note: XO can not accurate evaluate all quizzes yet, especially coding challenges. That is because currently, XO can not run the program, so it has to rely on reviewing the code. Also, XO is not smart enough to recognize all coding issues yet (though it is catching up fast!). To be safe, teachers may still need to review the final answers.

 
 

Generate Quiz for Any Difficulty Level

 

In the most basic format, you can ask XO to generate a random quiz by saying “give me a quiz on [TOPIC] with difficulty [LEVEL]”. The LEVEL can be 1, 2, 3 or 4, with 1 being the easiest. For example, when you say “give me a quiz on variables with difficulty 1”, you may get a response like this:

 
Now you can simply answer the quiz in the chat and get the result:

 
 

Specify Quiz Format

 

By default, XO will randomly select from these 3 formats: coding challenge, multiple-choice question and short-answer question. However, you can specify the format if you have a preference. For example, you can ask “give me a coding challenge on variables with difficulty 2”:

 
After implementing the solution, we can ask XO to check out solution by saying “check my code” or “check my answer”. If there is an issue, XO will point it out:

 
After fixing the issue, we can ask XO to check again by saying “check again” or “how about this new answer”:

 
 

Specify Quiz Theme/Story

 

Quizzes can be made fun when we add some “flavors” to them. Specifically, we can ask XO to generate quizzes with a given background story, character or theme. XO will be happy to do so. For example, you can pretend to be any character, like an Alien:

 
Below are some more examples that you can try:

• I’m Frodo and you are Gandalf. Give me a coding challenge on repeat loops
• It’s Earth Day. Write a level 1 coding quiz for using events that aligns with this theme.
• Give me a coding test on the <key pressed?> sensor block, and use the storyline of Star Wars
• As a wizard in Hogwarts, I need a quiz on cloning sprites using the “create clone of” block. Difficulty Level 2.

• I’m an alien exploring Earth. Create a coding challenge on broadcasting to communicate with my spaceship. Difficulty Level 4.

 
 

Specify More Details

 

XO can follow our instructions very well, so we can feel free to add more details to our request. Here are 2 examples.

Example 1 - Limit Scope of Blocks

Since XO may not know which blocks we already know, it may generate a quiz that uses some blocks that we are unfamiliar with. To avoid this issue, we can specify which blocks can be used like this: give me a coding challenge on clones. difficulty 1. note that I am new to Scratch and I can only use motion and event blocks

Example 2 - Reference the Project

Since XO can read the code in the playground, you can ask Xo to use that as a reference when creating the quiz. For example, you can open the Explore page and find an interesting game, then ask XO this: I’m a 5th grade teacher. I just explained this project to my class, and now I hope to test their understanding. Give me a multi-choice question of level 1 about how this project works.

 
 

Share Your Quizzes

 

If you have found any interesting way to prompt XO to generate quizzes, please feel free to reply to this post below with the request you used and XO’s response.

Introduction

 

This tutorial is designed primarily for K-12 educators, though students may also find it insightful.

As educators, one of our key goals is to provide students with constructive feedback that acknowledges their efforts and guides them towards improvement. Effective formative assessment is crucial in this process, as it helps highlight both strengths and areas for growth.

Nevertheless, crafting thoughtful and comprehensive feedback can be quite demanding. It requires a careful review of each element of a student’s work and a considered choice of words to ensure the message is both encouraging and instructive.

To address this challenge, XO has been developed to provide feedback on any given project when we provide it with a rubric. Here is how it works:

1. Teachers draft a rubric as part of the assignment, a common practice already in place.
2. Students, as they progress with their project, can request XO to assess their work according to the specified rubric. They can continue to seek feedback and make improvements until they are satisfied with their project.
3. Students submit the final project to their teachers for evaluation.
4. Teachers can review the log of XO conversations for each student and can also utilize XO to evaluate student submissions.

The key advantage of this approach is that it offers students instant, personalized feedback, significantly enhancing both the efficiency and engagement of the learning process.

 
 

Example Step 1 - Teacher Creates an Assignment

 

Let’s consider a scenario where a teacher has recently introduced the concept of the “broadcast message” block in class. Here’s an example of how an assignment using this concept might be structured along with its rubric:

Create a project that effectively demonstrates the use of message broadcasting between sprites.

Rubric:
1. The project must include at least two sprites, each with appropriately descriptive names.
2. At least one sprite should broadcast a message that another sprite receives and responds to.
3. All message names used should be clear and meaningful.
4. The project should narrate a coherent story, such as a dialogue between two people or an interaction between two animals.
5. [Extra credit] Implement a broadcast message that triggers simultaneous actions in two or more sprites.

 
 

Example Step 2 - Student Buiids Initial Project

 

Suppose a student creates an initial version of the project with 2 sprites like this:

Sprite “Sprite1”:

 
Sprite “Crab”:

 
Note that the Sprite1 is missing the “broadcast” block.

 
 

Example Step 3 - Student Gets Initial Feedback

 

Now, suppose the student asks XO for feedback. He/she needs to ask XO to “review the project for the given assignment”, then paste the assignment/rubric into the chat. Don’t worry about the format, as XO will still understand the request even if it is all in one line:

 
Note that XO has gone through every requirement in the rubric thoroughly, and it has correctly pointed out some issues, especially that “message1” is not sent out.

 
 

Example Step 4 - Student Improves Program

 

Next, suppose the student has updated the program to broadcast the message, and also renamed the message name like this:

Sprite1:

Crab:

 
 

Example Step 5 - Student Asks for Feedback Again

 

Now, the student can ask for another review by saying “review again” or “how about now”:

 
Note that the review has been updated to confirm the changes the student has made, and also encourage student to focus on the remaining issues.

The student can keep improving the project continuously until he/she is happy about it.

 
 

Notes on Writing Rubrics for XO

 

It’s important to understand that XO is capable of evaluating only the code blocks within each sprite. This means that XO is unable to assess several aspects of the project:

• Aesthetics: XO cannot “see” or evaluate the visual elements like costumes or backdrops on the stage.
• Runtime Issues: XO does not run the projects, so it cannot detect certain bugs or issues that only appear during execution.
• Project Description or Comments: XO is unable to read and interpret any written project descriptions or embedded comments.

Given these limitations, XO is best utilized for static analysis of the programming elements of a project.

 
 

Use XO to Write Rubrics

 

If you’re uncertain about how to write effective rubrics for XO, you’ll be pleased to know that XO can assist in writing the rubrics itself. Who doesn’t love an AI that can write instructions for itself?

For best results, here are some tips for asking XO to write rubrics:

• Provide as much details about the student and the assignment as possible;
• Include all key points you want to include
• If you already have a sample project, open it and ask XO to use this project as a reference
• Ask XO to improve until you are satisfied

 
Here is an example request:

I'm teaching fifth grade students how to use repeat loops in combination with variables. 
Write an assignment with rubric. It should cover variable initialization and variable
 updates inside the loop.

 
And here is an example output from XO:

Introduction

 

CreatiCode extends MIT Scratch by introducing a variety of new block categories including 3D game engines with physics capabilities, 2D physics, artificial intelligence, app widgets, multiplayer online games, augmented reality, and table variables. These additions allow for the creation of a much broader range of projects beyond what is possible with standard MIT Scratch.

Starting a new project can sometimes be daunting if you’re unsure of where to begin. This is when you can ask XO for help. XO has seen many different types of projects, so it can often make some suggestions on how to design a new project.

It’s important to remember that XO is primarily an assistant. While it can provide helpful tips and guidance, it cannot create an entire project on its own. XO is optimized for short, specific responses, and its performance may decline when tasked with generating lengthy replies. Moreover, as a coding learning tool, XO aims to enhance learning by encouraging students to engage more deeply with the programming process. Providing full code solutions would be counterproductive to this educational goal.

Also, XO can not generate original ideas: everything XO says is a response to your idea based on other existing projects that XO has seen before. For a project to truly stand out, your own creativity and vision are key. XO’s role is to assist in bringing your unique ideas to life, offering support and suggestions based on its vast database of project insights.

In this tutorial, you will learn how to use XO to design new projects.

 
 

Generate Project Outline

 

Whenever you come up with an idea, you can ask XO how to build it. XO would give you an outline of the project. You are use this as a baseline to estimate the complexity of the project, and whether you are ready for it.

For example, you can ask, “how to build a 3D platformer game?”, and here is an example response:

 
It typically follows this format:

• Overview of the project
• Key components (stage and sprites)
• Key logical steps to implement each component
• Tutorial or demo project links

 
 

Customize with More Details

 

If you simply provide a few words for your project idea, XO will respond with a fairly generic outline. To get more original results, you would have to provide more details. As a basic rule, as you provide more details, XO’s response will also become more unique.

For example, here is an updated request:

Tell me how to design a 3D platformer game, where the player controls an Alien that can both jump and change direction in the air, and the platforms are moving themselves, and there are enemies that fire lasers at the Alien. The Alien can also pick up awards to run faster or jump higher.

Here is what XO says about it. As explained before, the originality has to come from your input.

 
 

Start Small

 

Since XO can generate outlines for any project idea, it’s easy to be ambitious and aim for a project that might be too complex to manage effectively. For instance, numerous students have contemplated building “Minecraft in 3D” only to realize that such a project exceeds the typical scope of school assignments.

A key principle to follow is “don’t bite off more than you can chew.” This means you should aim for projects that are challenging yet still within your capabilities. As you develop your coding skills through continuous practice, you’ll be equipped to tackle increasingly complex projects over time.

 
 

Ask for Project Ideas

 

Sometimes you run out of ideas on what to build, you can also ask XO to give you some suggestions. For example, you can say: I want to build a project to practice how to use ChatGPT blocks, can you give me some ideas for small projects?

You will get a list like below, which may inspire you to find your own idea:

 
 

Focus on Specific Steps

 

After getting a project outline, most people are tempted to say this: “give me all the code!”. However, XO can’t simply convert the project design to a fully working project. Most likely, you will get a “disappointing” response like this:

 
So, what’s the right way to proceed? We simply need to focus on individual steps/features. For example, if we focus on the first step to set up the 3D scene, XO will be happily working with us again:
