学术科技节开幕式暨数学的应用及建模培训指导讲座
致金朝永院长的一封信
尊敬金朝永院长：
您好！
在这春暖花开的四月，广东工业大学即将迎来第十九届学生科学技术节。为了能充分调动我院学生对学术科技的积极性，鼓励更多的学生参与到学术科技之中，提升学生的创新意识和培养学生以学为乐、学以致用的能力。我院正积极创造条件，提供学生获取信息与交流学习的平台，相信会不断促进学生在数学应用领域创新意识的提高，提升学生在发掘、搭建数理与生活之间联系上的能力。广东工业大学应用数学学院《学术科技节开幕式暨数学的应用及建模培训指导讲座》初拟于20xx年4月22日（星期二）14:30—16:30(最终以您的空闲时间为准)，在广东工业大学龙洞校区教学楼216举行。
此前我们数次与我院不同年级的学生一起交流谈心。了解了我院学生在学习数学专业知识和数学建模方面的现状，发现了存在的一些困惑。我们总结出以下的具有代表性的问题：
（一）对数学领域的认知度不高，不清楚数学可以应用到哪些社会领域（只是对数学建模有些了解）；不知道如何将学习到的数学专业知识运用到日常学习、生活与工作中；不清楚如何把握数学特色在学术科技上进行创新，迫切希望得到正确指引。
（二）在我院金牌赛事--数学建模方面，低年级学生表现为对数学模型、数学建模的概念不甚清楚，对数学建模竞赛的相关信息、如何准备数学建模竞赛了解不清晰。
（三）中高年级表现为在参加数学建模竞赛上，对于如何组建团队、分工协作、数学建模竞赛中的时间分配、写作格式应该注意哪些关键问题存在疑惑。
面对以上的种种困惑，大大减弱同学们对学术科技的满腔的热情，使得学院在推进学术科技上止步不前。
基于同学们以上问题的考虑，以及学院发扬学术科技之风的迫切愿望。现盛情邀请在数学领域上见解深厚、热心数学建模指导的资深教授——金院长您出席学术科技节开幕式并作为我们的主讲嘉宾，将您在应用数学和指导数学建模竞赛方面的成功经验分享给同学们，让同学们有更加清楚的认识，为同学们科学正确定位给予指引，进一步营造学院浓厚的学术氛围。
此致
敬礼！
