It’s no secret that computer science departments have the highest dropout rates, and the number is even worse with online coding programs where 94% of students give up. When I was learning to code, I almost quit many times - only later did I recognize I struggled because the courses didn’t align well with how people learn.众所周知，计算机科学系的退学率最高，而在线编程课程的退课率更是高达94%。当我学习编程时，我几乎多次试图放弃，直到后来我才意识到我之所以困难重重，是因为这些课程与人们的学习方式不太匹配。

Learning is the process of transferring knowledge from one medium into the user's mind. Similar to other interactive coding platforms like Codecademy or CodeSchool, I’ve aligned CodeRoad with the science of learning: practice doing, quick feedback, gamification, and hints or help when learners get stuck.学习是将知识从一种媒介转移到用户的思维过程。与Codecademy或CodeSchool等其他交互式编程平台类似，我将CodeRoad与学习科学相结合：实践锻炼、快速反馈、游戏化和当学习者遇到困难时提供提示或帮助。

As long as interactive content remains difficult to produce, the primary medium for coding education will still be video and text. The tools for interactive content just haven’t been available… until CodeRoad.只要交互性内容仍然难以制作，编程教育的主要媒介仍将是视频和文字。交互式内容的工具一直无法达到预期，直到CodeRoad出现。
