Software Engineering - Essay Example Some of them are Waterfall model, Spiral Model, Rapid Application Development (RAD) model, Prototyping model, Incremental Model, Concurrent Development Model, Component-based model, Formal Methods model and Fourth Generation Techniques. All these models describe different processes that are used for development of software. Generally for new types of applications, Waterfall model, Spiral Model, Rapid Application Development (RAD) model and Prototyping model are not yet so standardised. For these types of application new models such as Incremental Model, Concurrent Development Model, Component-based model, Formal Methods model and Fourth Generation Techniques is commonly used with the combination with previous mentioned methodologies. These all methods provide the technical specifications for building software. They encompass a broad group of tasks that include requirements analysis, design, program construction (coding), testing, and support. These all tasks are performed for development of software. Next section will cover some commonly used software development methods with advantages/ disadvantages, and where it can be used for development of software (or applications). The Waterfall Model: It is also called as Software Development Life Cycle (SDLC) or Linear Sequential Model. It is the oldest and the most widely used paradigm for software engineering. The waterfall method attempts to pin down the requirements early in the project life cycle. After gathering requirements, software design is performed in full. Once the design is complete, the software is implemented. The Waterfall model suggests a systematic, sequential approach to software development that begins at the system level and progresses through analysis, design, coding, testing, and support. [Pressmen 2001] Software is integral part of a larger system or business; therefore initially requirements for

Esl423 8 practium experience - Essay Example They used the Wilson Fundations book for Word Work. It’s an excellent book as there is a suggested weekly plan provided for the study material. This certainly helps the teacher pace the class. For Reading, there was a new story everyday. I believe this practice of reading everyday would help them achieve that objective. Their objective was to identify concepts of print by distinguishing letters from words and recognizing that the latter are separated by spaces. My concern is the efficiency of the ‘read back’ exercise. Done as a group, it is difficult to check if a particular student was actually reading or just mimicking the others. I also encourage both oral and silent reading like Mrs. Beach. The Free Reading for 15 minutes was satisfactory, too. It allowed the students to test their reading skills on their own. One of the SIOP components encourages hands-on materials or manipulatives for student practice. (Haynes, 2004) Writing was the last part of the class. T o me, it served to assess the students’ reading as well as develop their writing skills. However, maybe the exercise should not be limited to journal writing only as they are still very young. They could also write short letters. Or, make short stories by writing simple sentences for a sequence of pictures. The SIOP component of Practice and Application was evident in this class because the language skills were integrated in the activities such as reading back, journal writing, discussion & oral reading. There were other SIOP components in play, too, like preparation and lesson
