项目式学习是一种以实际生活或化工生产中真实情景为基础的探究型学习模式，它强调学生在实践中学习，并通过小组合作解决实际问题，从而促进学生高阶思维的发展。与传统的工程思维不同，本文的工程思维的培养是指教师可以利用基本的工程思想和方法，通过项目式学习的方式帮助学生更好地了解和把握主要知识点，进而提升教学效果和学生的思维能力，使得学生养成具有创造性、科学性、价值性、权衡性等特点的思维学习习惯。通过项目式学习，我们可以让学生在“真实”的情景中探索和实践，从而培养他们的工程技术逻辑思维，并且可以很好地处理现实提问。这种方式与最新版《普通高中化学课程标准》中提出的要求相一致，从而最好地提升学生的学习效果。本研究旨在构建一种项目式学习模型，以培养学生的工程思维，并通过实践案例来提升学生的学习效果。为此，论文将详细描述该模型的构建过程和实施流程。
本研究对工程思维和项目式教学的国内外研究现状进行了深入探讨，明确了相关概念。在多元智能理论、建构主义学习、人本主义等思想的指引下，分析了项目式学习、基础教育中培养工程思维的学习的各个环节，得出了项目式学习和培养工程思维的一般模型，进而构建出培养工程思维的项目式教学模型，同时诠释说明其对应的评价的方案。依据理论研究综合完成硫酸亚铁铵的制备和工厂尾气脱硫脱硝项目案例的设计，并在某中学进行实践。开始前通过教师访谈了解学生目前的工程思维发展水平；然后再经过培养高中生工程思维的项目式学习的教学实践，最后回看课上录像、与听课教师联合考察量表观察学生课上表现，学生的自评互评，并使用设计的问卷进行工程思维测评。最终经过问卷统计、数据分析和学生的自评、互评探究基于项目式学习在培养高中化学工程思维的成效，使用访谈的方式知晓一线化学教学老师对于培养学生工程思维的评价和建议。
研究最终表明，基于项目式学习在培养高中化学工程思维中具有研究意义和价值，构建培养工程思维的项目式学习模型可为老师教学提供设计思路，高中化学中基于项目式学习培养学生的工程思维是有效的。

Project-based learning is an exploratory learning based on real situations or real scenes in chemical production, which emphasizes that students learn in practice and solve practical problems through group cooperation,so as to promote the development of students' high -level thinking. Different from traditional engineering thinking, the cultivation of engineering thinking in this article refers to the use of basic engineering ideas and methods by teachers to help students better understand and grasp the main knowledge points through project-based learning, so as to improve the teaching effect and ability. Let the students form a set of scientific, creative, balance, value and other characteristics of thinking habits. Through project-based learning, we can allow students to explore and practice in a realistic environment, so as to cultivate their logical thinking of engineering technology and deal with realistic questions well. This approach is consistent with the requirements proposed in the latest version of the "General High School Chemistry Curriculum Standards" to enable students to overcome practical difficulty in real-life , so that the best improve students' learning effects. This study aims to construct a project-based learning pattern to train students' engineering thinking and improve students' learning effect through practical cases. To this end, the construction process and implementation process of the model will be described in detail.
This study deep research the current status of  project-based studying and teaching both domestically and internationally. Guided by the acknowledge of various intelligences learning, and humanism, a detailed analysis was conducted on the various stages of project-based learning and their relationships. Construct a project-based learning model ,and simultaneously explain the corresponding evaluation plan. Based on comprehensive theoretical research, the preparation of ammonium ferrous sulfate and the design of a project case for desulfurization and denitrification of factory exhaust gas were completed, and practical application was conducted in a middle school. Before starting, understand the current level of engineering thinking development through teachers' interviews.Then, through the teaching practice of project-based learning to cultivate high school students' engineering thinking.Finally, look back the classroom videos and conducted a joint evaluation scale with the attending teachers to observe students' performance in class. We also conducted self-evaluation and mutual evaluation among students, and used the designed questionnaire for engineering thinking assessment.Through questionnaire statistics, data analysis and students' self-evaluation and mutual evaluation, we explored the effectiveness of project-based learning in cultivating high school chemical engineering thinking. We used interviews to know the evaluation and suggestions of front-line teachers to developing students' engineering thinking.
The research finally shows that project-based learning has research significance and value in cultivating senior high school chemical engineering thinking. Constructing a project-based learning model for training engineering thinking can provide design ideas for teachers' education. Project-based learning which is valid to developing students' engineering thinking in high school chemistry.
