Scenarios for considering OOP concepts

1 UML with single class
class, properties and data types, encapsulation, access modifiers, methods, constructor, instantiation, object and reference variable
2 UML Superclass and sibling subclasses
Person, Player, Coach
subclass, inheritance relationship, (super class, over-ride)
3 UML Class with associate class featuring an array of objects
Team Class with squad array of Player
storing references in an array for multiple objects of the same type
(associate relationship)
4 UML with array of superclass references to subclass objects (polymorphism)
PassengerList with Person array of Player and Coach objects
storing references in an array for multiple objects of different types

Features for consideration regarding OOP concepts in each scenario

UML of class(es)
code to create and use objects, no problem solving
visualisation of creation and use of objects instantiated from class(es)
related misconceptions for each scenario: symptoms
example: objects can be treated as records (based on similar dot syntax), encapsulated fields can be used without accessor method
a property (UML class) is the same as an instance variable (object)
A class is the same as an object
each object has its own copy of the method code
variables are storing multiple values, for each object
formative assessment questions to explore misconceptions in each scenario
(There are examples of formative assessment questions on CodeHS)
read and interpret UML,
read and interpret sample SQARL code for class(es)
simple code which leads to exposing correct and incorrect understanding
sample questions
consider using values from a class without accessor methods
consider UML and some code: how many classes are there, how many objects are there, how many methods, how many properties
read and interpret simple code, secure use of OOP terminology
setter methods
requirements based problem solving
exam style presentation, summative assessment
CD or music playList model
develop UML
create a method to compare two tracks and determine which has had most plays, display the title
calculate average number of plays
how to coach students to read the requirements, identify and explain requirements
how to coach code development
