A Specifications-Graded, Spice-Themed, General Chemistry Laboratory Course Using an Argument-Driven Inquiry Approach
This paper describes the creation of a second quarter of a two-quarter sequence of argument-driven inquiry general chemistry laboratories. The course contains four projects investigating the chemistry of spices (vanilla, cinnamon, spearmint, and cloves) and incorporates a structured review and hands-on applications of fundamental concepts necessary to transition between general and organic chemistry (colligative properties, TLC, synthesis, characterization tests, and unknown determination). The inquiry-based curriculum was designed to give students increasing responsibility and freedom to develop experimental design skills. Specifications grading is used to increase concept iteration and encourage teamwork among students. Survey results for student learning style, feelings about chemistry, and perception of the course format are compared for the first and second quarter courses. Changes in survey responses show higher average positive responses in many categories for the second quarter course.
期刊介绍:
The Journal of Chemical Education is the official journal of the Division of Chemical Education of the American Chemical Society, co-published with the American Chemical Society Publications Division. Launched in 1924, the Journal of Chemical Education is the world’s premier chemical education journal. The Journal publishes peer-reviewed articles and related information as a resource to those in the field of chemical education and to those institutions that serve them. JCE typically addresses chemical content, activities, laboratory experiments, instructional methods, and pedagogies. The Journal serves as a means of communication among people across the world who are interested in the teaching and learning of chemistry. This includes instructors of chemistry from middle school through graduate school, professional staff who support these teaching activities, as well as some scientists in commerce, industry, and government.
