Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of software development training, and particularly relates to a software development pre-job training method based on intelligent analysis. BACKGROUND

[0002] With the rapid development of information technology, the demand for high-quality talents in the software development industry is increasing. Pre-job training for software development positions, as a key link in the cultivation of development talents, usually helps students master the necessary technical skills through a series of courses and practical activities. However, the existing traditional pre-job training mode has many problems, especially in the personalization of training content and evaluation methods.

[0003] Traditional pre-job training usually focuses on uniform course content and teaching arrangements, and the learning path of students lacks personalized planning, making it difficult to adjust to the actual basis, learning progress and ability needs of each student. This mode makes the training inefficient and fails to fully tap the potential of each student. In the training process, theory and practice are often disconnected, and the content learned by students often does not match the development needs in actual work, resulting in a large gap between training results and actual work ability. The existing traditional training system usually relies on fixed evaluation methods, which cannot reflect the progress and ability improvement of students in the learning process in real time. The evaluation method is too single and cannot accurately measure the ability of students in engineering practice, code quality, team collaboration, etc. Especially it cannot meet the needs of modern software development environments such as agile development, DevOps tool chain, low-code platform, etc. The traditional training system also lacks a dynamic feedback mechanism for the improvement of students' skills, and students often cannot get targeted improvement suggestions and practical guidance in a timely manner, resulting in difficulty in quantifying and optimizing the training effect. The current pre-job training system does not fully combine emerging technical tools such as code quality detection tools, automated testing, continuous integration, etc., and lacks systematic tool chain training and practical guidance. These new technologies are crucial to modern software development, but due to the neglect of these tools in the traditional training system, students often cannot quickly adapt to the rapidly changing development environment after entering the workplace, affecting work efficiency and project quality.

[0022] Through static code analysis and development behavior log collection, integrating Git operation logs such as code submission frequency and refactoring behavior, an evaluation model containing code specification, debugging efficiency, and other indicators is built to construct a student capability profile. Integrating development environments and developing plugins, students can collect data in real time during development. Machine learning algorithms are used to analyze student operation data and adjust training content in real time.

[0023] Among them: the core method architecture of the system (1) Intelligent evaluation and portrait construction Build a digital portrait of the learner using multi-dimensional capability assessments such as coding ability, logical thinking, and engineering cognition; Analyze skill gaps through machine learning algorithms and generate personalized learning paths; (2) Dynamic course generation system Construct a skill tree in the field of software development based on knowledge graph technology, such as programming languages, frameworks, and engineering methods; Intelligently recommend learning paths combined with job demand graphs, automatically generate customized course packages; (3) Intelligent training platform Integrate code automatic review, error pattern recognition, and best practice recommendation functions; Embed project development environment, support AI-driven real-time coding assistance and debugging suggestions; (4) Closed-loop evaluation system Establish a multi-dimensional evaluation model for code quality, task completion, and collaboration ability; Adjust training intensity and knowledge density dynamically through learning behavior analysis, and make job recommendations; Among them: Key technology support Technical modules Application scenarios Multi-dimensional data collection Integrate data sources such as code submission records, online test results, and project collaboration logs.

[0024] Working principle: For example Figure 1As shown, the present application constructs a multi-dimensional ability portrait of students through intelligent data collection and analysis, realizes accurate training starting point positioning, integrates IDE plug-ins, Git log analyzers and biometric monitoring devices, captures 23 engineering indicators such as code submission frequency, debugging efficiency and cognitive load in real time, extracts implicit characteristics such as logical thinking and engineering awareness combined with XGBoost algorithm, generates 3D ability radar chart with time axis based on the dynamic portrait engine built on Elasticsearch, and establishes a skill tree model containing 832 technical concepts by means of knowledge graph technology, quantifies skill transfer relationship through Node2Vec algorithm, and provides data foundation for subsequent adaptive training, for example, when it is detected that the student's compliance rate in RESTful API design is low, the system will automatically mark the weak items in the engineering specification dimension.

[0025] The core intelligent teaching system adopts a multi-objective optimization algorithm to realize dynamic generation and path optimization of training content, and the course generation engine balances cognitive load and skill coverage based on the NSGA-II genetic algorithm, and generates progressive Jupyter Notebook teaching templates combined with Vygotsky's zone of proximal development theory, when the student has a typical error pattern in the Spring Bean assembly exercise, the system will insert Guice comparison teaching units in real time, and predict the forgetting curve trigger interval through a deep knowledge tracking model. Repeat, the intelligent training environment integrates Kubernetes multi-tenant isolation, Service Mesh traffic mirroring and other technologies, supports full-stack practice from microservice debugging to red-blue confrontation exercises, for example, when the student modifies the code with OWASP vulnerabilities in the VR collaboration space, the AI coach will recommend a refactoring scheme that meets the Clean Code specification.

[0026] The closed-loop evaluation system realizes continuous optimization and job adaptation of training effect through multi-modal data analysis, the system aligns the cross-modal features of code quality and document writing using the CLIP model, and applies the Transformer time series model to predict the leadership development curve, the process evaluation not only includes hard skill indicators such as SonarQube static analysis and Git collaboration network analysis, but also quantifies learning frustration through EEG and facial expression recognition, the knowledge distillation module will continuously extract the problem solving mode of the top 1% students, generate an interpretable teaching rule set through the MoE architecture, for example, when it is detected that the student is continuously timing out in the CI / CD pipeline exercise, the system will adjust the subsequent micro-lesson / experiment ratio in conjunction, and finally generate a job adaptation report containing market premium capacity prediction.

[0027] The above examples are only used to illustrate the technical solutions of the present application, and are not intended to limit the present application; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that the technical solutions recorded in the foregoing examples can be modified, or some technical features can be replaced by equivalent features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
