According to the students, the first few classes to wear equipment will take 20 minutes. Skilled, you can throw in the water and then wear, it will be much easier. After warming up, the teacher explained the skills of fixed-point suspension and controlled emergency swimming, which are the two techniques commonly used in diving, and need to be practiced repeatedly. "There are two kinds of water entry posture, drum regulation of ear flat pressure, surface mirror drainage method, rising speed can not exceed the spit bubbles, with the potential companion symbiotic breathing, trapped net fishing emergency treatment……" A student counted out the knowledge points that our teacher had told us in several classes.

Yang Yang 厦大又一“怪课”潜水课揭开面纱 把课堂搬到海底–福建频道–人民网 原标题:厦大潜水课 搬到海底上 “深藏不露”的厦大潜水课揭开神秘面纱 背30公斤气瓶 把课堂搬到海底 继高尔夫、棒垒球、爬树、帆船后,厦大开设的又一“怪课”前天揭开神秘面纱。25日晚上,厦门大学官微推送的一则关于《厦大特色体育课――揭秘“深藏不露”的潜水课》的文章,让厦大潜水课再次吸足大众眼球。 水下教学 穿装备就20分钟 背30公斤气瓶下水 巨大玻璃窗的另一边是厦大翔安校区游泳馆的泳池,清澈的池水泛着凉意跳跃着,潜水课就在这里上课。“抱着猎奇的心态而来,幻想着水下的童话世界,出乎意料,‘老师很凶’!”这几乎成了每个学生对潜水课的初印象。 穿装备是潜水课上同学们遇到的第一个难题。乌黑笨重的潜服,半人高冰冷冷的气瓶,鸭掌般巨大的脚蹼,可以罩住半张脸的面镜……复杂、闷热、沉重,但绝不会有人抱怨这些装备。“衣服很紧,很热。气瓶足足有30公斤,还要戴3-4个铅块,太重了,但当你下水之后,就会感谢它们了,没有它们,你沉不下去。” 据学生介绍,前几次课穿装备就要20分钟。熟练后可以扔到水里再穿,那样会容易很多。 热身过后,老师讲解了定点悬浮和有控制的紧急游泳上升的技巧,这是潜水时常用的两种技术,需要反复练习熟悉。“还有入水的两种姿势,鼓气调节耳平压,面镜排水方法,上升速度不能超过吐出的气泡,与潜伴共生呼吸,被困渔网紧急处理……”一名同学为我们细数了几节课下来老师讲过的知识点,当我们问老师哪一项最重要时,老师的回答是:“每一项。” 这些知识看似琐碎,但都是最实用的技能,不容一丝疏忽大意,关键时刻用得好是能保命的。 一旦有了过硬的技术和安全意识,潜水并不是多么危险的运动。技术和安全来自于认真对待,用心学习,潜水课从不允许学生请假,老师对学生的高标准严要求是对每一个学生负责到底的体现。 “我们最想教给学生的是过硬的技术和时刻紧绷的安全意识,有了这两点,潜水其实比你在运动场踢足球还安全。” 负责教授潜水的翁兴和老师表示。 下海上课很奇妙 学生连称“会上瘾” 潜水课大多数时候都在厦大翔安校区的游泳馆里开展,不过,每学期的最后一次课,老师们还会带着学生来到五缘湾大桥下,来一次下海体验,这也是最令学生们兴奋的。 “我们下到大概三四米,水好咸啊,泥好滑,我跪在底下,抓了一把淤泥。大概下潜太快了,耳朵很痛。” “仰着游到深水区的时候很兴奋。我们是沿着栈道的柱子下去的,发现柱子底部有很多小海螺,很惊喜,我们挖了些上来,它们其实很普通,但自己从海底带上来的感觉不一样。” “这边水下视野不太好,下去之后四周都是绿色的海水,看不到其他东西,瞬间被紧张和孤独感包围,那感觉还是挺难忘的。” “我们四个人一起潜下去的,之前训练很久了,老师也在身边,所以一点也不害怕,就是觉得好玩,我就蹲在水底左右张望,一个同学配重带少了,浮在那里很尴尬啊。” “潜水带给你新奇的视角,水中视野宽阔,生物繁多,那是一个新的世界。一旦潜下去,你会爱上这种感觉,会上瘾。” 学生们纷纷表达潜水课带给他们那些新奇、惊喜、特别的体验。 近200名学生选修过 女生比男生还多 据厦大海洋与地球学院的杨位迪介绍,厦大潜水课的开设与其他的特色体育课程一样,不单纯为了“好玩”。2014年,应海洋与地球学院海底考察的需求,学校专为海洋学院学生开设了潜水课。随着课程的成熟,潜水课开始面向翔安校区学生开放,每学期开两个班,每个班有20个名额,由翁兴和老师与黄桑波老师带班,两位老师轮流负责岸上教学和水下指导。 据了解,每次选课系统一开放,潜水课的名额都会被瞬间“秒”光。由于该课程要求男生连续游400米、女生连续游200米,而且上课强度比较大,所以后期任课老师还会再“筛”掉一些人,不过,绝大多数人都能坚持到最后。目前,已经有近200名学生选修过,其中女生的人数超过一半,比男生还多。 潜水分为很多种,从功能上讲,有工程潜水、军事潜水、休闲潜水等,从装备上看,分浮潜和水肺潜水。厦大潜水课教授的是水肺潜水,以休闲潜水为主要目的。潜水课的开设为师生的科研创新提供了有利的条件,三位老师今年都申请了与潜水相关的大创项目,从黄老师的休闲潜水常见状况分析,到翁老师对厦门周边潜水点的调研,再到杨老师的五缘湾海洋生物物种水下普查,一系列研究推进了海洋研究事业的发展。今年小学期,杨位迪老师为海地学院学生开设了水下摄影的选修课,反响很好,已有20名海洋方向的学生选修了水下摄影课。记者 林维真 通讯员 李静 蒋丽 杨位迪 文 图 (责编:林东晓、张子剑)相关的主题文章:
