1.3 Significance of the Project

1. Enhancing Accessibility to Quality English Education

The English Learning System (ELS) is designed to democratize access to high-quality English language education. By leveraging digital technologies, the ELS can reach a wide and diverse audience, including individuals in remote or underserved areas. This accessibility is particularly significant for learners who may not have access to traditional classroom settings or qualified English teachers. The system ensures that anyone with an internet connection can benefit from structured and comprehensive English language instruction.

2. Personalized Learning Experience

One of the key strengths of the ELS is its ability to provide a personalized learning experience. The system will use adaptive learning algorithms to tailor content and learning paths to the individual needs and proficiency levels of each learner. This personalization helps to keep students engaged and motivated, as they receive content that is relevant and challenging. It also allows for more efficient learning, as students can focus on areas where they need the most improvement.

3. Comprehensive and Structured Curriculum

The ELS will offer a well-structured curriculum that covers all essential aspects of English language learning, including vocabulary, grammar, listening, speaking, reading, and writing. The curriculum will be designed by experienced educators and language experts, ensuring that it aligns with recognized standards and best practices. This comprehensive approach helps learners develop a well-rounded skill set, preparing them for both academic and professional environments.

4. Immediate and Constructive Feedback

Providing immediate and constructive feedback is crucial for effective language learning. The ELS will incorporate advanced feedback mechanisms, including automated and human-assisted feedback, to help learners understand their strengths and weaknesses. This real-time feedback enables learners to make adjustments and improvements quickly, leading to faster progress and better retention of knowledge.

5. Interactive and Engaging Content

To keep learners engaged and motivated, the ELS will feature interactive and multimedia-rich content. This includes videos, audio clips, interactive exercises, and gamification elements. These features make the learning process more enjoyable and dynamic, which is especially important for maintaining the interest of younger learners and those who may find traditional learning methods less engaging.

6. Support for Standardized Test Preparation

Many non-native English speakers need to prepare for standardized tests such as TOEFL, IELTS, or Cambridge exams. The ELS will include specific modules and practice materials tailored to these exams, helping learners to familiarize themselves with the test formats and improve their scores. This support is particularly valuable for students aiming to study or work in English-speaking countries.

2 Process Model

2.1 Introduction to the Waterfall Model

What is the Waterfall Model?

The Waterfall Model is a linear and sequential approach to software development that follows a strict, step-by-step process. It is one of the earliest and most traditional models in software engineering, and it gets its name from the way each phase cascades into the next, resembling a waterfall.

Key Characteristics of the Waterfall Model:

Linear and Sequential Phases:

The model consists of distinct phases, and each phase must be completed before the next one begins. There is no overlapping or iteration between phases.

1. The advantages of waterfall model

Easy to understand and use

It represents all the tasks you want to accomplish in real life. For example, you need the requirements of the client. It contains different stages, each of which is only initiated upon completion of the previous stage.

Specific deliverables and review process.

Each stage has a specific deliverable and audit process. After the demand phase, we meet all the requirements of the customer's needs. After the software development is completed, we can deliver it.

The stages do not overlap.

In this model, the phases do not overlap, meaning they are completed once at a time. After the previous stage is completed, only the next stage begins. For example, the development phase will only begin upon completion of the design phase.

(2) Disadvantages of Waterfall Model

The product has been online for a long time.

The product will only be released after completing all stages. Therefore, this model requires a long time to release products.

Unexpected results. Expectations and received content are mostly different, as customers only understand the product based on the documentation. The customer has only one idea, which is a recorded idea.

Not suitable for changing needs.

The waterfall model is not suitable for projects with moderate to high risk of demand changes. If there are changes in requirements, it is not recommended to use this model as all requirements are completed during the requirements phase, which is a very time-consuming process.

2.2 Application of the Waterfall Model

The Waterfall Model is a linear and sequential approach to software development, where each phase must be completed before the next one begins. This model is particularly well-suited for projects with well-defined and stable requirements, such as the development of an English Learning System (ELS). Below, we will explore the application of the Waterfall Model in the context of an ELS project.

3.2 Requirements Analysis

The English Wisdom Learning System is an application developed based on the Vanilla framework, aiming to improve students' autonomous learning ability, reduce teachers', and promote the innovation and development of English education. This system allows users to achieve online translation, personalized push messages, and other functions. In order to the effective utilization of educational resources, the following functional modules are designed.

Firstly, the login registration module allows users to create personal accounts and log in to the to enjoy personalized learning services. After successful registration, the system should be able to recommend appropriate learning resources and courses based on users' personal information and learning needs. new users use the system for the first time, they need to perform registration operations, create personal accounts, and set passwords. Registered users can log in to the by entering their usernames and passwords to enjoy personalized learning services.

The English video playback feature is an intuitive and vivid learning method provided by the system. It allows users to improve their listening skills and sense by watching English videos. The video content should cover various scenes and topics to meet users' different learning needs; at the same time, the video difficulty should set in levels to accommodate learners with different English proficiency. During the video playback process, basic operations such as pause, fast forward, and fast rewind are supported;, a subtitle display function is added for users to learn by comparison. Pop-up function: During the video playback process, the system can pop up提示 information or to related learning resources as needed, helping users expand their learning content and depth. Users can post comments while watching videos, exchange insights and opinions with other learners, the interactivity and fun of learning. Users can utilize fragmented time to watch English videos, improving their listening skills and language sense. Users can learn practical oral expressions communication skills by watching videos.

Let's talk about the daily tweet module again, which is a means of continuous learning provided by the system to users. By regularly pushing selected learning content, it helps users maintain their enthusiasm for learning and improve their English level. The system should recommend appropriate users to follow based on users' learning history and preferences. When users log in to the system every day, they can see the selected content pushed by the system, including various forms such as articles, pictures, videos.

The Chinese-English translation feature is a core function within the English learning system, allowing users to quickly convert between Chinese and English during learning process, thereby enhancing learning efficiency. The translation results are accurate, avoiding semantic errors or grammatical issues, ensuring that users do not get confused due to translation during their learning process. The translation response speed is fast, allowing users to quickly receive translation results after inputting text, avoiding long wait times. For professional vocabulary industry terms, the system can provide accurate translations, meeting the needs of different learning fields. The translation interface should be simple and easy to operate, while also providing translation options and settings to meet users' personalized needs. When users are reading English articles and encounter words or sentences they do not understand, they can use the Chinese English translation feature to quickly look up the meaning. When users are writing in English, they can use this feature to convert their Chinese thoughts into English expressions, improving efficiency.
