CS Discoveries 2019-2020: Data and Society Lesson 5.4: Representing Images
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

In this lesson students learn how computers represent images. To begin the lesson they consider the challenge of turning all the complexity of vision into a binary pattern. Through a series of images showing how this transformation is made students are introduced to the concept of splitting images into squares or "pixels" which can then be turned on or off individually to make the entire image. Students then do a short set of challenges using the Pixelation Widget in order to draw black and white images. Puzzles are designed to call out some of the challenges of representing images in this way. In the wrap up students make connections between the system for representing images and the system for representing text they learned in the previous lesson.

In this lesson, students learn about the binary number system. With a set of cards that represent the place values in a binary (base-2) number system by a collection of dots, students turn bits "on" or "off" by turning cards face up and face down, then observe the numbers that result from these different patterns. Eventually, students extend the pattern to a generic 4-bit system.

In this lesson, students use all three types of binary representation systems (ASCII characters, binary number, and images) to decode information in a record. After seeing a series of bits and being asked to decode them, students are introduced to the idea that in order to understand binary information, they must understand both the system that is being used and the meaning of the information encoded. They then decode a record representing a pet based on a given structure.

In this lesson students design a structure to represent their perfect day using the binary representation systems they've learned in this chapter. Students will first write a short description of their perfect day and then review with a partner to identify the key pieces of information they think a computer could capture. As a class students will decide how a punch card of bytes of information will be interpreted to represent those pieces of information. Students will then use the ASCII, binary number, and image formats they have learned to represent their perfect days. Students then trade punch cards and try to decode what the other student's perfect day is like. The lesson ends with a reflection.

Rating
0.0 stars

In this lesson, students use the problem solving process from earlier in the course to solve a data problem. After reviewing the process, the class is presented with a decision: whether a city should build a library, pet shelter, or fire department. Students work in teams to collect information on the Internet to help them decide what should be built, then use this information build an argument that will convince the city council of their choice. They then map what they have done to the problem solving process that they have been using throughout the course, comparing the general problem solving process to its specific application to data problems.

CS Discoveries 2019-2020: Interactive Animations and Games Lesson 3.11: Booleans and Conditionals
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

Students start by using booleans to compare the current value of a sprite property with a target value, using that comparison to determine when a sprite has reached a point on the screen, grown to a given size, or otherwise reached a value using the counter pattern. After using booleans directly to investigate the values or sprite properties, students add conditional _if_ statements to write code that responds to those boolean comparisons.

Students learn about collision detection on the computer. Working in pairs, they explore how a computer could use sprite location and size properties and math to detect whether two sprites are touching. They then use the `isTouching()` block to create different effects when sprites collide, including playing sounds. Last, they use their new skills to improve the sidescroller game that they started in the last lesson.

Students learn to combine the velocity properties of sprites with the counter pattern to create more complex sprite movement. In particular students will learn how to simulate gravity, make a sprite jump, and allow a sprite to float left or right. In the final levels of the Code Studio progression students combine these movements to animate and control a single sprite and build a simple game in which a character flies around and collects a coin. Students are encouraged to make their own additions to the game in the final level.

Students learn how to create functions to organize their code, make it more readable, and remove repeated blocks of code. An unplugged warmup explores how directions at different levels of detail can be useful depending on context. Students learn that higher level or more abstract steps make it easier to understand and reason about steps. Afterwards students learn to create functions in Game Lab. They will use functions to remove long blocks of code from their draw loop and to replace repeated pieces of code with a single function. At the end of the lesson students use these skills to organize and add functionality to the final version of their side scroller game.

Conditional Remix & Share Permitted

Rating
0.0 stars

In this lesson, students are introduced to boolean values and logic, as well as conditional statements. The class starts by playing a simple game of Stand Up, Sit Down in which the boolean (true/false) statements describe personal properties (hair or eye color, clothing type, age, etc). This gets students thinking about how they can frame a property with multiple potential values (such as age) with a binary question.

From there students are provided a group of objects with similar, yet varying, physical properties. With a partner they group those objects based on increasingly complex boolean statements, including compound booleans with AND and OR.

Finally we reveal Conditionals as a tool to make decisions or impact the flow of a program using boolean statements as input.

In this multi-day lesson, students use the problem solving process from Unit 1 to create a platform jumper game. They start by looking at an example of a platform jumper, then define what their games will look like. Next, they use a structured process to plan the backgrounds, variables, sprites, and functions they will need to implement their game. After writing the code for the game, students will reflect on how the game could be improved, and implement those changes.

Students will plan and build their own game using the project guide from the previous two lessons to guide their project. Working individually or in pairs, students will first decide on the type of game they'd like to build, taking as inspiration a set of sample games. They will then complete a blank project guide where they will describe the game's behavior and scope out the variables, sprites, and functions they'll need to build. In Code Studio, a series of levels prompts them on a general sequence they can use to implement this plan. Partway through the process, students will share their projects for peer review and will incorporate feedback as they finish their game. At the end of the lesson, students will share their completed games with their classmates. This project will span multiple classes and can easily take anywhere from 3-5 class periods.

Students explore the challenges of communicating how to draw with shapes and use a tool that introduces how this problem is approached in Game Lab. The warm up activity quickly demonstrates the challenges of communicating position without some shared reference point. In the main activity students explore a Game Lab tool that allows students to interactively place shapes on Game Lab's 400 by 400 grid. They then take turns instructing a partner how to draw a hidden image using this tool, accounting for many challenges students will encounter when programming in Game Lab. Students optionally create their own image to communicate before a debrief discussion.
