摘要： 当前在大学生涯之中,有机化学实验教学的基本过程之中会出现一些问题,比如学生们在实验的时候会遇到实际问题,但是不能够正确的通过有机化学相关理论知识来解决。实验内容也十分分散,而且知识之间没有相应联系。在化学实验教学之中,培养学生们对于化学知识学习的创新能力原动力不充足等等,所以本文主要针对教学过程之中,针对学生们的科学引导自身的重要性,只有将理论以及实践进行结合,才可以使得学生们在实验的时候,做到将知识融会贯通,真正的理解化学教材之中所学到的相关知识。

摘要： An operationally simple, reliable synthesis of ethynylated acenes suitable for an upper-division undergraduate organic chemistry laboratory course has been developed. This experiment requires students to synthesize two acene derivatives and can be completed in 6-8 laboratory sessions (3 h each);a shorter experiment could be realized in the synthesis of only one product. Synthesis is carried out by first treating a terminal alkyne with n-butyllithium in an oven-dried flask under nitrogen at 0 degrees C. An acene quinone is added, which produces a doubly ethynylated diol. Dehydration with SnCl2/HCl yields a bis(ethynylated) acene, which is purified via a short pad or column of silica gel. The intense colors of the products allow for great ease in determining reaction completion and following the products in chromatography. UV-vis and fluorescence spectroscopy may be used to better understand the effect of molecular structure on electronic properties.

摘要： Successful mastery of multistep synthesis is an essential learning objective in the completion of the organic chemistry sequence. This entrepreneurial class project was designed to incentivize students to master multistep synthesis through role-playing as an entrepreneur. In short, students play the role of a group member in a startup whereby they must work with a group in their assigned role to create a multistep synthetic route. This startup presents their synthetic route history, synthesis, and financial cost of a target molecule to the investor (faculty). The results of this class project demonstrated improvement in the overall retention of multistep synthesis pathways as monitored by a paper summative assessment question.

摘要： Aldol chemistry is highlighted in many introductory organic chemistry laboratory experiments because it provides synthesis, mechanism, and experimental challenges for students. In the experiment described here, students synthesize dibenzalacetone derivatives by crossed aldol condensation, observe reaction rates using a semiquantitative rubric, and illustrate the connection between reactant structures and reaction rate through their knowledge of the reaction mechanism. By combining class data and working through a guided-inquiry questionnaire, students link reaction rates with nucleophile and electrophile characteristics of the reactant structures. Independent rate determination of the aldol addition step, using UV absorption, confirmed that student rate observations of the overall reaction are a valid approach to learning about structure-function effects.

摘要： An emergent theme from the past spring during COVID-19 remote learning was the difficulty of providing meaningful, relevant, hands-on, wet chemistry experiences at home and the potential impact of their absence upon student learning and engagement. This article shares the process and results of developing an appropriate, easy, inexpensive, safe, and relevant hands-on, at-home DIY kit of wet laboratory activities for a first-semester high school organic chemistry course. Troubleshooting, tips, handouts, and evidence of learning and engagement are provided to supplement the already-published procedures for many of the activities. Whether instructors have already started teaching or are preparing for an upcoming course, this article should enable the rapid incorporation of an at-home laboratory curriculum to supplement student learning and promote engagement with appropriate alternatives to traditional experiments.

摘要： 自学能力是学生必须培养的能力之一,而考试是一种能够相对准确反应学生学习情况的常用考查形式。以有机化学课程为载体,选取了一些知识点完全交给学生课下自主学习,然后在期中或期末考试中选取部分自学内容进行考查。通过对比前后3个学期考试成绩的变化,以及期末考试卷面自学知识点得分率与课堂讲授知识点得分率之间的差距,发现在教师做好引导与课后答疑的前提下,考试卷面中有8~10分的题目交由学生课下自学不会对考试成绩产生不良影响。本研究为短学时课程变相地增加了学时数,为确定课程中合适的自学比例提供了一定的实践依据。
