This article is a discovery-based instructional resource for faculty to use as a capstone course or exploratory project for undergraduates who are familiar with (but not necessarily fluent in) calculus, linear algebra, complex variables, and geometry. The explorations flow from a simple change in sign: in the complex numbers a + bi, where…

Chemistry curricula in part rely on the use of laboratory demonstrations and experiments. The complex nature of this kind of educational activity has been posing challenges from the very early days of teaching chemistry. As chemistry is an experimental science, one possible approach to make the teaching of this subject more efficient is to use…

In a typical chemistry instrumentation laboratory, students learn analytical techniques through a well-developed procedure. Such an approach, however, does not engage students in a creative endeavor. To foster the intrinsic motivation of students' desire to learn, improve their confidence in self-directed learning activities and enhance their…

The classroom exercise outlined here is a self-directed assignment that connects students to the environmental contamination problem surrounding the DePue Superfund site. By connecting chemistry knowledge gained in the classroom with a real-world problem, students are encouraged to personally connect with the problem while simultaneously…

Based on the dozens of interactive workshops that the author has facilitated with children, he has discovered that children are more knowledgeable about the natural and the built environment than typically accredited. Due to this discovery, he believes children should be part of the community engagement for planning projects, developments, and…

Teaching remote sensing in higher education has been traditionally restricted in lecture and computer-aided laboratory activities. This paper presents and evaluates an engaging inquiry-based educational experiment. The experiment was incorporated in an introductory remote sensing undergraduate course to bridge the gap between theory and…

In the STEM classroom, students can work in collaborative teams to build those essential skills needed for the 21st-century world. In project-based learning (PBL), teams of four to six students are often randomly selected to describe a realistic situation that may occur in today's workplace; this may be done by counting off in fours, fives,…

Central to The Lab School model is Sally Smith's Club Methodology, the full immersion of students into a time period where historical information is learned through multi-sensory activities. While immersed, through the use of costumes and elaborately decorated classrooms, students are engaged in project-based learning. As the student's…

In this experiment, organic chemistry students perform reactions between three naphthyl acetate derivatives and the diazonium salt Fast-Red TR, under basic conditions. The three naphthyl acetate derivatives used in this study are 2-naphthyl acetate (1a), 6-bromo-2-naphthyl acetate (1b) and 1,6-dibromo-2-naphthyl acetate (1c). The two-step, one-pot…

The scientific discovery process comes alive for 70 minority students each year at Uniondale High School in New York where students have won top awards for "in-house" projects. Uniondale High School is in a middle-income school district where over 95% of students are from minority groups. Founded in 2000, the Uniondale High School Research Program…

Two projects, the reaction notebook and the end-of-semester synthesis activity are described which could help students to adopt a discovery-based learning and engage students in practical applications of chemistry. Students have provided positive feedback on this classroom assignment and have felt that it has helped them crystallize their thought…

As his geology students' specialized knowledge of the Mesozoic era increased, a high school teacher realized he needed a way to showcase their work. The Mesozoic Resource Center's biggest hit was a walk-through diorama showing how life might have been during each of three Mesozoic periods. Highlights included two gigantic student-built dinosaur…

Southeastern New Hampshire schoolchildren are involved in three network science projects for grades 2-8: Batnet, Birdnet, and Treenet. The listserv projects were developed by a group of teachers interested in using the computer-Internet connection to enrich and extend the science learning. Network science makes topics more real, lends immediacy to…

A science teacher at an Alaska correspondence school discusses the educational uses of electronic mail (enhancing the relationship between teacher and distant student, encouraging early computer literacy and reflective communication skills, and promoting interschool collaboration) and describes a telecommunications-based science project involving…

Describes the ninth-grade curriculum of the Downingtown Educational Enrichment Program (DEEP) that includes student design and implementation of independent-study contracts. The program serves identified gifted students through a year-long scheduled elective course option that meets every other day and offers one-half credit. (CR)
