Open Source Software in Education

     In recent times I have started a job as a computer teacher for a private school, and as such I have had to become familiar with a variety of educational software. As an educator, it is important for there to be a plethora of accessible software to teach children digital literacy, as computers have become increasingly incorporated into more facets of modern society Open-source software is one avenue that allows young students access to important tools to learn and create, without incurring a hefty price tag for their school. This is especially true for those learning how to code since it is not exactly a subject that comes naturally to everyone. While there are certainly many free IDEs out there for any aspiring adult programmer to use, I am more concerned with young children who may not be able to understand all the complex operations of standard IDEs. The best answer I have found is the educational coding software Scratch, created by MIT. Licensed under the “Creative Commons Share Alike” license, Scratch provides a drag and drop block-based coding environment that is easily understood and accessible to children. This allows teachers to easily demonstrate basic coding concepts like if-then-else statements and assigning variables. There’s even Scratch jr., available on tablets, that has an even more simplistic UI designed for even younger audiences. MIT has also released App Inventor, a free open-source software for creating mobile applications. These coding applications highlight the ability of open-source software to easily adapt to changes in social needs. But educational software does not just encompass programming and mobile apps, it also extends to various tools needed for academic success. Software such as ONLYOFFICE and LibreOffice, which provides a free alternative to Microsoft Office, is appreciated by students who cannot afford the more popular and expensive version. Not only are these applications useful within the U.S. education system, but another benefit they provide is their international reach. Since they are online and free for anyone to download and copy, they can be distributed to anyone globally with an internet connection. This opens new avenues for providing education to those in need. Education is a sector in need of accessible tools so that we can better teach the next generation and expand access to reliable education within our own borders and beyond. Not only that, but in this modern time where the importance of digital literacy is at an all-time high, we need to start laying the groundwork for future developers.

GRASP (General Responsibility Assignment Software Patterns) in Software Engineering (Week-9)

In the realm of software development, particularly object-oriented design, GRASP (General Responsibility Assignment Software Patterns) plays a pivotal role in shaping efficient and maintainable software. This set of principles, first introduced by Craig Larman in his 1997 book “Applying UML and Patterns,” serves as a critical design tool, not just for software development but also as a mental toolkit for understanding and applying design principles.

GRASP encompasses nine fundamental principles: Controller, Creator, Indirection, Information Expert, Low Coupling, High Cohesion, Polymorphism, Protected Variations, and Pure Fabrication. These principles are not new inventions but rather documentation and standardization of old, tried-and-tested programming principles in object-oriented design. They are instrumental in solving common software problems and enhancing the readability, scalability, and maintainability of code.

One of the key principles of GRASP is the Information Expert. This principle suggests assigning responsibilities to the class that possesses the necessary information to fulfill them. In essence, the class with the most information required to fulfill a given responsibility should be the one to undertake it. This approach not only streamlines the process of assigning responsibilities but also ensures that they are placed where the most knowledge and capability reside.

Another essential pattern is the Creator. It deals with the creation of objects, a common activity in object-oriented systems, and suggests that the class that uses or has the initializing information for an object should be responsible for creating it. This principle helps in defining clear relationships between different classes and their objects, thereby making the system more intuitive and easier to manage.

The Controller pattern is crucial for handling system events. It assigns the responsibility of dealing with these events to a non-user interface class that represents the overall system or a specific use case scenario. The controller coordinates and delegates the work that needs to be done to other objects, acting as a central point of control without taking on too much work itself. This pattern is fundamental in defining how interactions within the system are managed and is a key part of the application/service layer in an object-oriented system.

Understanding and applying GRASP principles is vital for any software developer working in object-oriented design. These patterns provide a framework for assigning responsibilities within a system, ensuring that each part of the codebase is both efficient and purposeful. By adhering to these principles, developers can create software that is not only functional but also easy to understand, extend, and maintain. This knowledge is not just technical but conceptual, offering a deeper understanding of how to approach software design in a methodical and thoughtful manner.
