Therefore, this paper aims to delve into the specific impact of STEM education methods on the comprehensive development of students and to construct a scientifically sound evaluation system, providing theoretical and practical guidance for the implementation and improvement of STEM education. Through such research, we hope to offer effective educational strategies for cultivating innovative talents who can meet the de-mands of future societal development.

2. Overview of STEM Education Methods

2.1 Definition and Characteristics

STEM education is an integrated educational model that organically combines four disciplines: Science, Technology, Engineering, and Mathematics. Compared to traditional education models, a notable characteristic of STEM education is its interdisciplinarity. It not only emphasizes the teaching of disciplinary knowledge but also places importance on the interconnection and comprehensive application of disciplines. Through interdisciplinary teaching methods, students can develop their thinking and innovation abilities comprehensively while solving real-world problems.

2.2 Teaching Models

STEM education employs various teaching models, among which inquiry-based and project-based teaching are the most common and effective. Inquiry-based teaching encourages students to actively pose questions, conduct investigations, and experiment to discover answers (Ning Junkang, 2023). This teaching model stimulates students' curiosity and desire to explore, cultivating their independent thinking and problem-solving abilities. Project-based teaching, on the other hand, focuses more on students' practical operations. By completing specific project tasks, students can integrate theoretical knowledge with practical skills, thereby deepening their understanding and mastery of knowledge. A commonality be-tween these two teaching models is that they both emphasize students' active participation and practical experience, ena-bling students to think and explore more actively during the learning process and thereby better cultivate their compre-hensive qualities.

3. The Connotation of Students' Comprehensive Qualities

3.1 Knowledge and Skills

In today's rapidly developing society, students' comprehensive qualities not only include traditional disciplinary knowledge but also encompass various essential skills. Scientific knowledge enables students to understand the laws of nature, technological skills allow them to use modern technological tools, engineering design capabilities equip them with the ability to solve practical problems, and mathematical logic skills form the basis for cultivating students' abstract think-ing and logical reasoning abilities. The integration of this knowledge and skills is an important foundation for students to adapt to future societal development and is also the core content emphasized in STEM education.

3.2 Innovation and Collaboration

Innovative thinking and teamwork abilities are important aspects of students' comprehensive quality development, play-ing crucial roles in today's society and future workplaces. In STEM education, the cultivation of these abilities is given special attention.

Innovative thinking is the core of students' comprehensive qualities, encompassing not only independent thinking and innovation consciousness but also the ability to accept and apply new knowledge. In STEM education, students are en-couraged to break traditional thinking patterns, boldly explore unknown fields, and propose innovative questions and solutions (Wang Lei, 2022). For example, when studying biology, students might explore how to use biotechnology to improve the yield and disease resistance of crops. Such exploration not only deepens students' understanding of scientific knowledge but also cultivates their innovative thinking.

Teamwork ability is an indispensable skill for students in their future careers. In STEM education, through team projects and collaborative experiments, students learn how to play their roles in a team, how to effectively communicate and collaborate with people from different backgrounds. These collaborative experiences not only improve students' efficiency in solving problems but also cultivate their leadership and sense of responsibility. For instance, in a project about sustainable energy, students need to jointly research the advantages and disadvantages of different energy sources and design a set of energy solutions suitable for the local environment. This requires students to engage in ample communi-cation and collaboration to complete the task together. Problem-solving ability is another important component of students' comprehensive qualities. In STEM education, students cultivate this ability by solving real-world problems, which involves analyzing and understanding the problem, formulating and implementing solutions, and evaluating the results. Through these activities, students learn how to face challenges, how to remain calm and creative when confronted with difficulties.

4. The Impact of STEM Education on the Comprehensive Development of Students

4.1 Enhancement of Knowledge and Skills

STEM education, by integrating theoretical knowledge from science, technology, engineering, and mathematics with practical activities, has been widely proven to effectively enhance students' knowledge and skills. In implementation, students not only learn the foundational theories of various disciplines but also apply this theoretical knowledge to solve real-world problems. A specific empirical study example is the observation and recording of changes in students' levels of knowledge and skills application through a robotics design project. Through pre-designed test questions and practical operation assessments, significant improvements were observed in students' abilities in physics principles, mathematical knowledge, programming, and engineering design. Specifically, students were tested on mechanics and electrical circuits knowledge before and after the project, and the results showed that the average scores increased from 60% at the begin-ning of the project to 85% at its conclusion.

The emphasis of STEM education on data analysis and mathematical modeling capabilities was evidenced by another study focused on a bridge construction project. In this project, students were required to collect relevant data and apply mathematical models to predict the load-bearing capacity and stress distribution of the bridge. Researchers assessed the improvement in students' mathematical modeling capabilities by comparing their abilities at the beginning and end of the project, finding significant enhancements in their capacity to solve engineering problems using mathematical models. This assessment was conducted through specially designed mathematical modeling tests and the evaluation of the quality of project reports, which included the accuracy, complexity, and innovation of the mathematical models as assessment criteria.

In terms of technological skills, the impact of STEM education was quantified through a series of operational tests related to technology tools students use daily. These tests were designed to evaluate students' proficiency in using computer software, programming languages, and electronic devices. Students underwent these tests before and after partici-pating in STEM projects, and the results indicated a noticeable improvement in their use of technological tools, particu-larly in mastering programming languages and the proficient operation of electronic devices.

4.2 Cultivation of Innovation Ability

Cultivating students' innovation skills is one of the key goals in STEM education, having significant implications for their future learning and career development. To quantify the impact of STEM education on students' innovation abilities, a study employed a mixed-methods approach, integrating qualitative case studies with quantitative surveys. The research began by designing a comprehensive project involving renewable energy, such as student teams designing and construct-ing small solar energy devices, serving as a platform for exploring the application of knowledge in physics, chemistry, and engineering. The purpose of the project was to encourage students to transcend traditional thinking patterns and attempt innovative methods and solutions.

To assess the enhancement of innovation skills, researchers developed a set of assessment tools, including tests for innovative thinking, observational records of technical operational abilities, and project evaluation forms. These tools were designed to measure the differences in students' innovation abilities at the start and end of the project. The study also included an assessment of students' participation in extracurricular activities and competitions, such as robotics con-tests, and how these activities fostered students' innovative thinking and practical abilities.

Quantitative data collection utilized a pre-and-post-test design, with students completing the same test for innovative thinking at the beginning and end of the project. By comparing the test results, researchers were able to assess the im-provement in students' innovation abilities. Furthermore, the study included a self-assessment questionnaire for students, aimed at understanding their perceptions of their own innovation abilities and technical operational skills, as well as their satisfaction with the STEM learning experience.

The results showed that after participating in the interdisciplinary STEM project, students' average scores on the innovation thinking test significantly increased, indicating that STEM education effectively promoted students' innovation abilities. Self-assessments of students' technical operational skills also showed positive progress, particularly in programming and engineering design. Moreover, students who engaged in extracurricular activities and competitions demon-strated higher innovation abilities and team collaboration spirit.

4.3 Cultivation of Team Spirit

In STEM education, the cultivation of team spirit is an important aspect, which not only helps to improve students' effi-ciency in problem-solving but also helps to develop their social skills and teamwork abilities. Through team projects and collaborative tasks, students learn how to effectively communicate, collaborate, and resolve conflicts within a team, which are crucial skills for their future careers and personal development.

For example, in a team project related to environmental science, students may need to jointly investigate a water quality issue in a region and propose improvement plans. This requires team members to have a clear division of labor, closely cooperate, and each take on certain responsibilities while contributing their own expertise. In this process, students not only learn how to effectively utilize their knowledge and skills but also learn how to listen to others' opinions, respect different viewpoints, and play their roles in the team.

In addition to team projects, STEM education also promotes collaboration among students through other means, such as group discussions, peer reviews, and collaborative experiments. These activities require students to communicate and collaborate within the group to complete tasks together, thereby deepening their understanding of scientific concepts and enhancing their collaboration skills.

STEM education also emphasizes cross-cultural cooperation and global awareness. In some international collaboration projects, students have the opportunity to work with classmates from different cultural backgrounds to address global issues. These cross-cultural collaboration experiences not only enhance students' global perspectives but also cultivate their cultural sensitivity and adaptability.

STEM education has a positive impact on the development of students' comprehensive qualities. By integrating disci-plinary knowledge into practical activities, STEM education not only enhances students' knowledge and skills but also cultivates their innovation abilities and team spirit. The improvement of these comprehensive qualities enables students to better adapt to the development needs of future society and become talents with innovative spirits and practical abilities.

5. Evaluation of the Effectiveness of STEM Education

5.1 Evaluation Indicators

In assessing the effectiveness of STEM education, the use of scientifically sound evaluation indicators is crucial. These indicators must cover aspects such as knowledge acquisition, skill application, and innovative performance, and should be implemented through carefully designed and validated assessment tools.

To ensure the relevance and effectiveness of the evaluation indicators, educational researchers conducted an extensive literature review to identify common learning objectives and outcomes in STEM education. Through expert consultations and focus group discussions, these initial indicators were further refined and categorized. The expert group included teachers in the STEM fields, education scholars, and students directly involved in STEM education, ensuring that the evaluation indicators reflected the core values of STEM education from multiple perspectives.

Subsequently, to validate the reliability and effectiveness of these evaluation indicators, researchers designed a series of pilot tests. This included constructing test questions, observation sheets, and scoring criteria for different evaluation indicators. For instance, to assess students' knowledge acquisition (Li Zhen, Li Xiaohong, & Chen Chen, 2021), a set of test questions covering scientific principles, mathematical concepts, and engineering technology was designed. The as-sessment of skill application included direct observation of laboratory operations, mechanical fabrication, and computer programming, along with corresponding scoring standards. For innovative performance, an evaluation framework was developed to quantify the level of innovation and practicality in students' design of new devices, development of new solutions, or presentation of unique perspectives.

These assessment tools were trialed on a sample of an appropriate size to collect feedback and conduct preliminary data analysis. Based on the results of the trials, the assessment tools were adjusted and optimized as necessary. This ensured that they could accurately measure students' performance in STEM education while also considering the practicality of the evaluation process and the convenience of educators.

Building on the development and validation of the assessment tools, a series of evaluation studies were conducted, employing various research designs such as cross-sectional studies and pre-post comparison studies, to ensure the relia-bility of the findings. In these studies, students' performance was recorded using a variety of data collection methods (Zhou Jing, 2021), including test scores, observation records, and self-assessment questionnaires. The data analysis meth-ods were also diverse, including both descriptive statistics and more complex statistical tests such as T-tests and ANOVA, to identify the impact of STEM education on different evaluation indicators.

5.2 Evaluation Methods

When evaluating the effectiveness of STEM education, adopting an evaluation strategy that combines quantitative and qualitative methods provides a comprehensive perspective. This integrated approach not only measures students' knowledge and skill levels but also delves into their learning experiences and innovative processes. Here are the details on how these evaluation tools were developed and validated, and their application in actual research.

The development of quantitative evaluation tools began with the identification of evaluation indicators, which include students' scientific knowledge, mathematical abilities, and engineering skills. The development process involved design-ing standardized test questions and questionnaires aimed at objectively measuring students' specific competencies in the STEM fields. For example, the assessment of scientific knowledge might be conducted through multiple-choice questions, while the evaluation of engineering skills might include assessments of practical operations. These tools were validated through pilot testing with a target group. Feedback from the pilot tests was used to adjust the test questions and scoring criteria to ensure the accuracy and fairness of the tests. The results of the standardized tests provided a quantitative dataset for analyzing students' performance in STEM education.

The development of qualitative evaluation tools focused on capturing students' learning experiences, thought processes, and innovative performances. This included the development of observation guides, interview outlines, and frameworks for analyzing works. These tools aimed to record and interpret students' behaviors, reflections, and creative outcomes while participating in STEM projects. To validate the effectiveness of these tools, researchers conducted pilot studies, collected data through observations and interviews, and conducted preliminary analyses to assess the sensitivity and ap-plicability of the tools. This process might involve detailed documentation and analysis of students' interactions during the projects, their reflections on the projects, and the products they created.

In actual evaluation studies, quantitative and qualitative evaluation methods were used concurrently to gain a compre-hensive understanding of the effectiveness of STEM education. The research design was typically multimethod, combin-ing questionnaire surveys, standardized tests, participatory observations, and semi-structured interviews. For instance, in one study, researchers might first assess a group of students' mathematical and scientific capabilities through standardized tests, then explore students' innovative processes and teamwork methods in completing an interdisciplinary STEM project through observations and interviews. The sample selection aimed to cover students of different ages, genders, and educa-tional backgrounds to ensure the broad applicability of the research findings. After data collection, quantitative data were interpreted through statistical analysis, such as calculating mean scores, and standard deviations, and conducting correla-tion analyses. Qualitative data were processed through content analysis and thematic coding to identify key themes and patterns in students' learning and innovation processes.
