Introduction to Programming

Lesson Objectives

Students will be able to:

• Identify and locate bugs in a program.

• Translate movements into a series of commands.

Vocabulary

• Algorithm 算法 - A list of steps to finish a task. 完成一项任务的步骤列表。

• Bug 错误 - An error in a program that prevents the program from running as expected. 程序中的一个问题，阻止程序按预期运行。

• Debugging 调试 - Finding and fixing errors in programs. 查找并修复程序中的错误。

• Sequencing 指令排序 - Putting commands in the correct order so computers can read the commands. 将命令按正确的顺序排列，以便计算机能够读取这些命令。

• Looping/Iteration 循环 - The process of repeating a set of instructions or a block of code until a certain condition is met. 重复执行一组指令或代码块，直到满足某个条件的过程。

Algorithm 算法

• A list of steps to finish a task. 完成一项任务的步骤列表。

Debugging 调试

• Finding and fixing errors (Bugs 错误 ) in programs. 查找并修复程序中的错误。

Sequencing 指令排序

• Putting commands in the correct order so computers can read the commands. 将命令按正确的顺序排列，以便计算机能够读取这些命令。

Looping/Iteration 循环

• The process of repeating a set of instructions or a block of code until a certain condition is met. 重复执行一组指令或代码块，直到满足某个条件的过程。

Decompose it! - 将其分解！

• Break problems down into steps - 将问题分解成步骤

• What should it do first? - 它首先应该做什么？

• What should it do second? - 它其次应该做什么？

• Does it repeat any actions? - 它有重复的动作吗？

• You could use a loop! - 你可以使用循环！

  • Use a pencil to sketch out each step if it’s helpful. - 如果有帮助的话，可以用铅笔勾勒出每一步。
