摘要： We report a series of experiments based upon cinnamon oil that were developed to provide a practical integration of green and sustainable chemistry concepts for the organic chemistry laboratory. Five experiments centering around cinnamaldehyde as a green, plant-based chemical were performed by undergraduate students in a second-year organic chemistry class. Cinnamon oil was obtained through hydro-distillation, and cinnamaldehyde was used to demonstrate the use of a secondary metabolite in chemistry laboratories. Subsequently, a reduction reaction, aldol reaction, and Schiff base formation were carried out. Through these experiments, students are able to practice techniques such as thin-layer chromatography, column chromatography, recrystallization, and measurement of melting points along with UV, FTIR, and H-1 NMR spectroscopy. Microscale practices were employed in each of the reactions, and microscale column chromatography was used for purifications. The final experiment was an antimicrobial activity assessment of cinnamon oil and the cinnamaldehyde derivatives obtained from the previous experiments. Along with an interdisciplinary component, students were exposed to sunscreen chemistry and were led to consider the many uses of each product obtained. These experiments were based upon a single, inexpensive plant metabolite and biobased material to educate students about green chemistry and its practical applications in the undergraduate laboratory.

摘要： In organic chemistry, meaningful learning is essential when reflecting about multiple reaction pathways and selecting reaction centers-topics that require a complex and multivariate reasoning approach to problem-solving. Meaningful learning is characterized by abstract, analytical thinking that might be time-consuming, whereas rote learning, on the other side of the continuum, facilitates simple heuristic-based recall of information. To challenge organic chemistry students to shift their problem-solving approach from rote learning to meaningful learning, we designed task sequences that initially required students to use heuristics followed by an enforced reflection about alternative reaction pathways. Twenty-nine students who were enrolled in a third-year organic chemistry course participated in the study. They solved two tasks, each with four subtasks, which sequentially provoked the use of different problem-solving approaches. The tasks are centered on the chemical concept of nucleophilicity and electrophilicity. In the first step, students were prompted to predict the product of an easy and familiar reaction. This step aimed at provoking the use of heuristics. Afterward, students received five alternative product cards and were prompted to reflect on the plausibility and the alternative mechanistic pathways leading to these products. Evaluation of these task sequences revealed (a) to what extent students were engaged in reflecting on their own problem-solving approaches and (b) the aspects students perceived as important for adopting a more meaningful approach to solving typical tasks in organic chemistry. Implications and limitations of the designed tasks are discussed.

摘要： Reaction mechanisms commonly used in organic chemistry are a great challenge for students in terms of understanding the representation and inferring the appropriate chemical concepts. In order to support the process of identifying and selecting chemical concepts, purposefully designed case comparisons are widely used. While these tasks place great demands on students' problem-solving capabilities, it is unknown how learners distribute their attention on the complex and information-rich representations. Understanding students' visual decoding behavior when dealing with case comparisons could provide valuable insights into supporting students' problem-solving process. In this exploratory study, we employed eye-tracking methodology to observe beginner and advanced undergraduate chemistry students when working through case-comparison tasks. By establishing a novel eye-tracking measure, the fixation/transition ratio, distinct viewing behaviors could be observed. Results indicate significant differences between both status groups. Advanced students are overall faster in their decision-making and transition more frequently between the representations, indicating a higher selectivity for chemically relevant entities. Further, the results show a significant impact of the visual complexity of a representation on students' visual behavior. Implications for designing case comparisons and supporting students' decoding process are discussed.
