Model Student Environmental Contract Laboratory

化学（12）州长州立大学正在开发一个示范学生环境合同实验室（SECL），以改善环境化学课程的教学。环境化学课程是两门课程所必需的，化学学士学位与教师教育证书（中学认可）和化学教学专业化的基础教育学士学位，也是美国化学学会批准的化学课程中的高级选修课程。该SECL适应NSF 9750477在沿海卡罗莱纳大学开发的课程，以分析环境样本所产生的学生注册的类和“客户”，包括GSU生物课程和当地高中教师和高中学生的项目。SECL配备了一台新的火焰原子吸收光谱仪和石墨炉原子化自动进样和PC控制。块消化系统有助于更大容量的学生分析。该大学现有的GC/ MS的自动采样配件也装备了SECL。参加环境化学课程的学生创建SECL，执行USEPA监管方法，制定适当的QA/QC程序，并在模拟实验室审计期间进行评估。他们的经验增强了学生在工业工作场所的入门级职位的准备。这种准备对于GSU学生来说至关重要，因为化学专业的BS是非传统学生（平均年龄29.9岁），回到教室完成专业教育或改变职业。超过80%的化学专业学生参加GSU兼职，在下午晚些时候，晚上和星期六课程招生。新的仪器还提供了远程访问仪器操作的地区高中教师。这种远程访问允许参与的高中教师提高他们在课堂上的效率，丰富课程，课外活动，如俱乐部，学生项目和指导调查。与高中教师和他们的高中学生的合作是根据我们的CCLI A I项目99550554“一个基于WWW的区域FT-NMR化学改进”所获得的经验开发的。"

Chemistry (12) Governors State University is developing a model Student Environmental Contract Laboratory( SECL) to improve instruction in the Environmental Chemistry course. The Environmental Chemistry course is required in two curricula, the BS in Chemistry with a Teacher Education Certificate (secondary school endorsement) and the BA in Elementary Education with Chemistry Teaching Specialization, and also is an advanced elective in the American Chemical Society approved BS in Chemistry curriculum. The SECL adapts the curriculum developed in NSF 9750477 at Coastal Carolina University in order to analyze environmental samples generated by the students enrolled in the class and for 'clients', including GSU biology courses and local high school teachers and high school student projects. The SECL is equipped with a new an atomic absorption spectrometer with flame and graphite furnace atomization with autosampling automation and PC control. A block digestion system facilitates greater volume of student analyses. An autosampling accessory of the university's existing GC/ MS also equips the SECL. The students enrolled in the environmental chemistry course create the SECL, perform USEPA regulatory methods, develop appropriate QA/QC procedures, and are evaluated during a mock laboratory audit. Their experiences enhance student preparation for the entry level positions in the industrial workplace. Such preparation is critical for GSU students since the BS in Chemistry majors are non- traditional students (29.9 average age), returning to the classroom to complete professional education or to change careers. Over 80% of the chemistry majors attend GSU part-time, enrolling in the late afternoon, evening and Saturday course offerings. The new instrumentation also provides remote access to the instrumentation for operation by regional high school teachers. This remote access allows participating high school teachers to enhance their effectiveness in the classroom, with enrichment of curriculum, in extracurricular activities such as clubs, and in student projects and guided inquiry. The collaboration with high school teachers and their high school students was developed based on experience gained through our CCLI A&I project 99550554, "A Regional WWW-Based FT-NMR for Chemistry Improvements."
