Codesters 的介绍可耕不需要先修的知识, 并会给你足够的背景让你立刻开始自己的项目。在Codesters 的介绍后, 学生们已经准备好进入到 Python 介绍中完整的40课了。
Students are introduced to the basics of creating interactive and animated programs in Codesters by using the drag and drop tools along with the text based code editor. Students will customize, debug, and create their own interactive greeting card.
学生们学习如何使用坐标平面，从而在控制台上移动他们的精灵。他们在标准笛卡尔网格上的所有四个象限点上工作。学生学会运用和扩展他们对坐标平面的知识来完成有意义的任务。
学生学习如何在画布上添加各种颜色和大小的形状, 以得到任何他们想要的图片。通过学习如何添加和更改形状, 学生会自然地理解变量并使用函数和对象的参数。
Each project-based lesson has around 20 activities and its divided into 3 phases: Build, Modify, and Create. The activities in the Build and Modify phases are automatically graded, including debugging and assessment activities. The capstone Create project for each lesson is graded by the teacher using a rubric provided by Codesters.
Students start by building an example project, through which they develop key coding skills. Debugging activities help students learn specific rules about syntax and the structure of code. Assessments include multiple choice questions and journal responses.
Once students have built their example project they are asked to customize the program to solidify their understanding and demonstrate proficiency with the skills they learned.
Students create a new project from scratch that uses the same core skills skills they developed in the example project. This capstone project for each lesson creates opportunities for students to deepen their understanding and to demonstrate mastery of coding topics.
Our curriculum is aligned to the CCSS Standards for Mathematical Practice as well as Computer
Science standards from the most recent draft of the CSTA K-12 Standards (K-8). For Mathematical
Practice standards we address problem-solving skills, perseverance, strategic planning, and place value on developing
an efficient problem solving approach. For Computer Science we address the standards
identified in the Algorithms and Programming.
CCCSS MP1: Make sense of problems and persevere in solving them.
In each lesson, students are given direct instruction as they build a example program that includes the programming
concepts the lesson addresses. Throughout the build process, students are intermittently asked to solve "debugging"
challenges that ask them to figure out a common problem and find a way to fix it. As a culminating activity for each
lesson, students are given a real-world based programming challenge that allows them to use the skills they've
practiced in the lesson.
CCSS MP7: Look for and Make Use of Structure.
The first lessons in our curriculum stress the importance of order and simple data structures in programming.
Programs run in order; students create programs that follow a single path from beginning to end. As they build their
example programs, they get instructions, examples, and non-examples that start to bear out the kind of structure
that is inherent to high quality programs. When they are asked to create their own original programs, they make
use of the structural elements from the lessons.
CCSS MP8: Look for and express regularity in repeated reasoning.
Our curriculum starts students as beginning text-based programmers. Their first tasks are to use pre-built commands
delivered in a certain order so that they get a certain visual outcome. This approach allows students to see
specific output/visual feedback that relates to the individual commands they’ve used.
K-12 CSTA Framework Concept: Algorithms and Programming.
All of our lessons have been developed with this framework concept in mind. We provided scaffolded instructions that
walks students through the most basic programming concepts to levels where students are dealing with sophisticated
and abstract programming concepts.
有了Codesters，学生将通过创建有趣和吸引人的项目来学习编程。每节课都是作为学生设计的项目而构建的。每个项目都会向学生介绍新的编程主题和概念，同时强化他们已经学过的内容。例如，在石头剪刀布中，学生学习使用if语句将他们的选择与计算机的随机选择进行比较，并决定谁胜出。为了创建他们想要的项目，学生们将有动力坚持学习编程。而且他们很享受这个学习过程。
教师在帮助学生学习用Codesters编程方面发挥着至关重要的作用。教师可以在控制面板上的查看每个学生的进度，看看哪些学生在哪里遇到困难。他们甚至可以深入查看学生提交的没有得到满分的实际代码。这有助于教师了解学生的学习情况，并引导他们成为专业的编程人员。
学生按照项目课程的“构建”和“修改”阶段中的说明进行操作，可以立即得到有关错误的反馈。这个反馈既包含学生友好的错误信息，也包含内置于自动评分系统中的提示和建议。即时反馈有助于学生理解和纠正错误，并顺利完成学习编程之路。
