1User-centric computer programming describes programs where the computer user, rather than the programmer, determines the order of actions in a program.
- ATrue
- BFalse
2Suppose an event occurs twice and an event handling method is called twice. When the second event occurs, objects in the Alice world may not be in the same position as they were when the first event occurred.
- ATrue
- BFalse
3In an interactive program the sequence of actions is determined at runtime.
- ATrue
- BFalse
4A method that does very little other than organizing the calls to other methods is known as __________.
- Aan implementation
- Ban inheriting method
- Ca driver
- Dworld.my first method
5Write a method and test it, write a method and test it, until the program is completed. The previous sentence describes a program development strategy known as ____________.
- Ainteractive development
- Bsequential processing
- Cstepwise refinement
- Dincremental development
- Ainteractive development
6What is the advantage of incremental development?
- AIt makes it easier to execute a program -- running an Alice world.
- BIt makes it easier to debug a program.
- CIt makes it easier to call methods from "world.my first method".
- DIt makes it easier to write a program.
- AIt makes it easier to execute a program -- running an Alice world.
7Events are world-level.
- ATrue
- BFalse
8Functions allow you to _______________.
- Aspeed up or slow down a playing world
- Bcheck certain conditions within a world while an animation is running
- Cchange the state of a world

9An If/Else statement makes a decision based on ______________.
- Athe arguments given to a method
- Bthe ordering of statements
- Cthe value of a condition as a program is running

- Athe arguments given to a method
10A Return statement is optional in a function.
- ATrue
- BFalse
11Functions are an example of abstraction.
- ATrue
- BFalse
12Logical operators can be found _____________.
- Ain the list of World properties
- Bin the Camera
- Cin the list of World functions

13What does a class define?
- Athe types of "blocks" dragged into Alice code, such as "Do together" and "loop"
- Bthe folder from which an Alice object is found
- Ca particular kind of object
- Dthe properties of the world, such as where the camera is facing
- Athe types of "blocks" dragged into Alice code, such as "Do together" and "loop"
14What is a method?
- Aa coordinated sequence of instructions that will be carried out when requested
- Busing Alice control structures such as a "Loop" to shorten code
- Can elegant and efficient way of programming
- Dan object instantiated from a class
- Aa coordinated sequence of instructions that will be carried out when requested
15Methods that specifically reference more than one object are typically written as world-level methods in Alice.
- ATrue
- BFalse
16One purpose of methods is to _____________.
- Adivide a program into small manageable pieces that work together to create a meaningful whole
- Ballow non-interactive code to execute differently each time an Alice world is run
- Ccreate a distinction between built-in Alice objects and modified Alice objects
- Dallow two different objects to be instantiated from the same class
- Adivide a program into small manageable pieces that work together to create a meaningful whole
17Although primitive methods are built-in to Alice objects, these primitive methods cannot be used in methods defined by the programmer.
- ATrue
- BFalse
18Since objects can be passed to a method via parameters, it is perfectly acceptable to pass a sound file to a method via parameters.
- ATrue
- BFalse
19All objects of the same class share some commonality.
- ATrue
- BFalse
20Calling world-level methods should from within a class-level method generally is not good programming practice.
- ATrue
- BFalse
21The term iteration means the same as the action of looping.
- ATrue
- BFalse
22The keyword ________ signals the presence of looping.
- AWHILE
- BDO
- CIF
- DNOW
23An Alice object understands movement commands in up, down, left, right, forward, and backward directions based on ______________.
- Athe object's own sense of direction
- Bthe direction the world is pointing
- Cthe position of the camera
- Dhow close it is to another object
- Athe object's own sense of direction
24Each object in Alice has a unique "center".

- BFalse
25Alice is based on the use of ___________ .

- Dnow
29What is a control structure?

- Bthe use of built-in functions specifically written such that collisions can be avoided
- Ca slide which allows the programmer to control how fast the world is played
- Da programming statement that allows the programmer to control the order in which instructions are executed
- Athe ability to resize and reposition an object once it is dragged into the world
30Conditional execution is best described as ____________.
- Awhen some condition is checked and a decision is made about whether (or not) a single instruction in the program code will be executed
- Bwhen a section of code is run a number of times
- Cwhen some condition is checked and a decision is made about whether (or not) a certain section of the program code will be executed
- Dthe difference between using a "do together" versus a "do in order"
- Awhen some condition is checked and a decision is made about whether (or not) a single instruction in the program code will be executed
31Conditional execution makes use of functions and expressions to check a current condition in the world.
- ATrue
- BFalse
