《建筑环境学》以研究建筑热湿环境、空气环境、声光环境和室内空气品质为主要内容，研究的主要问题大多源于建筑实际微环境对人体舒适及健康的影响，旨在创造健康、舒适和安全的居住环境，是一门反映人－建筑－自然环境三者之间关系的科学，在建筑环境与能源应用工程专业培养方案中占据重要地位。本课程涉及的理论知识具有跨学科综合性、前沿性，且与实际生活息息相关，适合学生进行自主研究。在教学环节中增设自主实验研究环节，有利于培养和提升学生运用理论知识解决实际复杂综合问题的能力，锻炼其沟通表达、团队协作等综合素质。在本《建筑环境学》教学中，为了激发学生的学习热情和创新意识，培养和提升学生运用理论知识解决实际复杂问题的综合能力，作为课程体系建设的重要内容，在教学环节中突出增设了自主实验研究。配合自主研究，引导学生自主选题，合理制定研究计划和完成实验。 本文归纳了大连理工大学建环专业《建筑环境学》课程执行自主实验研究20年的过程中，学生自主选题情况、研究对象类型、相应研究方法、实验仪器应用与更新变化的进阶成效，并对学生在工程知识、问题分析及综合能力提升等方面进行了统计评估。研究发现，随着实验仪器测试参数及记录功能的完善，极大地拓宽了学生自主实验研究的选题范围；社会高速发展，需要学生同时具备扎实的理论知识和更强的实践能力。因此，近年来50%以上的学生倾向于选择复杂环境影响因素的建筑作为研究对象，100%采用非单一研究方法开展实验研究，从多方面锻炼自己的专业技能，以求顺应国家发展的人居环境建设要求。自主实验研究环节使学生深刻认识到室内外环境调控的机理、目的和手段，亦培养了学生制定、实施研究计划、撰写论文的能力，以及综合应用所学知识发现问题、分析问题、解决问题的能力。另外，对学生课后调查发现，学生在课程中对终身学习和价值观培养两方面的体会不深，在未来的教学中应加强对学生学习习惯和伦理道德方面的综合培养。 本文结合实际教学效果阐述了《建筑环境学》课内自主实验研究对工科基础课学习的作用，并分析了科技、社会等因素对教学过程和效果的影响。此外，结合历届学生对该课程学习过程的评价与收获，不断思考如何培养创新型研究人才，力求能够为学生提供更加全面的能力提升平台。本文详细分析了学生自主实验研究过程中出现的各种问题，并有针对性地提出了改善意见，对《建筑环境学》及其他工科课程的建设及发展提供了参考。

Building Environment studies the thermal and humid environment, the air environment, the sound and light environment, and the indoor air quality of buildings as the main content. This course plays an important role in training programs for engineering in construction environments and energy applications. The main research concerns the impact of the actual microenvironment of buildings on human comfort and health, with the aim of creating healthy, comfortable and safe living environments. It is a science that reflects the relationship between humans, buildings and the natural environment. The theoretical knowledge involved in this course is interdisciplinary and advanced, and closely related to practical life, making it suitable for students to conduct independent research. Independent experimental research is conducive to training students in the ability to use theoretical knowledge to solve practical complex problems and to exercise their communication, expression, teamwork and other qualities. Teaching studies in the built environment lack tracking and statistical analysis of long-term teaching reform projects, and in particular, in-depth research and analysis of specific student practice projects. In order to stimulate students' learning enthusiasm and innovation awareness, cultivate and improve their overall ability to solve practical complex problems with theoretical knowledge, independent experimental research is highlighted in teaching sessions as an important component of curriculum system construction. Cooperate with independent research, guide students to choose their own topics, reasonably formulate research plans, and complete experiments. This paper summarizes the progress of students' self-selected topics, types of research objects, corresponding research methods, application and updating of experimental instruments during the 20 years of independent experimental research of the Built Environment course of environmental construction major of Dalian University of Technology, and makes a statistical assessment of students' engineering knowledge, problem analysis and comprehensive ability improvement. It was found that as science and technology developed, the variety of experimental instruments became more complete and could achieve more functions, greatly broadening the range of independent experimental research topics available to students. The rapid development of society has placed constant and high demands on students, demanding both solid knowledge and greater practical ability. Therefore, in recent years, more than 50% of students tend to choose research objects with more complex influencing factors, and 100% of students use non-single research methods to carry out experimental research, and exercise their professional abilities from various aspects in order to comply with the requirements of the development of The Times. Independent experimental studies enable students to gain an in-depth understanding of the mechanisms, purposes and means of indoor and outdoor environmental regulation. It also develops students' ability to formulate and implement research plans and write papers, as well as their ability to find, analyze and solve problems by fully applying what they learn. Post-school surveys of students found that students did not have a deep understanding of lifelong learning and the cultivation of values in the curriculum, and future teaching should strengthen the cultivation of learning habits and ethics among students. In contrast to other previous papers, the features and innovations lie in the following. First, it analyzes the statistical data of 20 years of teaching, expounds the role of independent research on the learning of basic engineering courses combined with years of statistical data and actual teaching effects, and analyzes the influence of science and technology, society and other factors on the teaching process and effect. The second is to incorporate the assessment and harvest of previous students into the curriculum learning process, to constantly think about the future development and reform direction of the curriculum, and to strive to provide a more comprehensive platform for students to improve their abilities. In this paper, various issues in the process of student independent experimental research are analyzed in detail and some suggestions for improvement are made, providing a reference for the construction and development of Building Environment and other engineering courses.
