String |
| Loop | A sequence of instructions that continually repeats until a conditional is met. |
| Iteration | A process of repeating a set of instructions a specified number of times or until a condition is met. Such as in a repetition of a process or a newer version of development in computer science. |
| Professional | A way of behaving, dressing, and communicating with people that is respectful of everyone’s backgrounds and opinions. |
| Problem Decomposition | The process of breaking a complex problem or system into parts that are easier to conceive, understand, program, and maintain. |
| Sprints (sprint task list) | A list of the individual parts that need development to address a backlog item. |
| Abstraction | A technique or process that manages complexity in a program or computer system. Abstraction “hides” details or removes duplication, allowing the programmer to focus on high-level considerations and functions rather than the rules of a programming language. |
| Arithmetic Operator | A symbol in code that tells a computer to perform a specific math operation, such as addition, subtraction, multiplication, or division. (+ - x /). |
| Logical Operator | A representation of a logical statement that is used to examine the relationship between two values and determine whether the statement is true or false (Boolean conditionals). Examples of logical operators include AND, OR, and NOT. |
| Conditional Statement | A programming statement that evaluates a true/false Boolean expression to determine the next steps in a program. Conditional statements are often written as ‘if-then’ or ‘if-then-else’ statements. |
| String | Text or characters displayed by a program. In MIT App Inventor block mode, a text block lets you manage how text or “strings” will be presented to the user of an app. |
| integer | A whole number that does not have a decimal or any digits after the decimal. |
| Boolean Expression | A processing decision branch using comparison operators ( = ≠ > <) that is defined to return a Boolean value (“true” or “false”). By using Boolean expression to ask questions, the program can determine what to do next. |
| Boolean Value | One of two values, such as “true” or “false”, that allows a computer to know what step in the conditional statement process to execute next. |
| Algorithm | A set of steps to accomplish a task. An algorithm can be expressed in many kinds of notation, such as natural language, pseudocode, and flowcharts. Algorithms are essential to the way computers process data because they contain the specific instruction for what a computer or program does. |
| Debugging | To identify errors or bugs in computer hardware or programs and fix them. |
| Local Database | A storage space on a device used to store information from an app. |
| Index | A specific location by order for an individual element in a list. The position of an item in a list is often called its index. In MIT App Inventor, the first item in a list has an index of 1, the second has an index of 2, and so on. In Python, the first index is represented by 0. The plural form in indices. |
| Chained Conditional Statement | A series of conditionals that a computer moves through until it finds the one that is true. |
| Code | A set of program instructions. |
| Concatenation | A joining together of separate items, without changing them, into one place. For example, the concatenation of two strings such as “Hello” and “world!” would return “Hello world!”. |
| Event | An action or occurrence that happens during runtime that will trigger a response or behavior by the software. An event can be user input, such as clicking a button, or external, such as a device receiving an SMS text message. |
| Event Handler | In MIT App Inventor, a control block that looks for inputs or events to know when to perform a specific action. |
