Three direct complexometric titration methods for bismuth subsalicylate determination in over-the-counter stomach relief caplets and liquids are presented, as well as a UV-vis assay, for use in student laboratories. The main difference between titration methods is the choice of indicator; either xylenol orange (XO), pyrocatechol violet (PV), or…

Chemistry laboratories ordinarily involve a number of visual observations and require qualitative and quantitative explanations of these observations. A student with blindness at Truman State University successfully completed the laboratory portion of the non-majors liberal arts chemistry course with the assistance of a senior undergraduate…

This paper describes the adaptation of an upper-division undergraduate seminar course taught at the University of Missouri in Columbia (MU) to the Summer School Program of the University of Chinese Academy of Sciences in Beijing (UCAS). The course "Scientific Writing in Chemistry" addresses an essential need for science students across…

We describe a 3-hour session that provides students with the opportunity to review basic lab concepts and important techniques using real life scenarios. We began with two separate student-engaged discussions to remind/reinforce some basic concepts in physiology and review calculations with respect to chemical compounds. This was followed by…

Introductory chemistry courses are required as part of the undergraduate preparation necessary for entry into an array of professional programs. Given the varied priorities of the student population in these courses, it can be difficult to present the material such that students see their individual future academic priorities represented in each…

Freshman science courses are intended to prepare students for the rigor and expectations of subsequent college science. While secondary education aims to prepare students for the college curriculum, many incoming freshman lack the sense of responsibility for their own learning that is essential for success in a college-level course. The freshman…

Laboratory capacity is an issue that has plagued education for more than a century. New buildings, late night classes, and virtual laboratories have offered transitory relief at great expense. Missouri University of Science and Technology is employing blended strategies to increase capacity and student success. Blended strategies expand learning…

The first courses freshman university students typically enroll in are the introductory science and math, courses that bridge from and build upon their prior educational experiences. These introductory courses often have large enrollment lectures coupled with supplemental sessions to teach using traditional educational practices, which may operate…

A writing-intensive, upper-level undergraduate course which integrates content, context, collaboration, and communication in a unique fashion, is described. The topic of the seminar is "Scientific Writing in Chemistry" and an assignment-based curriculum was developed to instruct students on best practices in all aspects of science…

IT WAS THE PURPOSE OF THIS RESEARCH TO ASSESS THE CONTRIBUTION OF CERTAIN SCIENCE COURSES AND OTHER FACTORS THAT MAY INFLUENCE STUDENTS' UNDERSTANDING OF SCIENTISTS, THE AIMS AND METHODS OF SCIENCE AND THE SCIENTIFIC ENTERPRISE. THE SAMPLE CONSISTED OF 1,275 PHYSICS STUDENTS AND 1,009 CHEMISTRY STUDENTS FROM HIGH SCHOOLS IN IOWA, KANSAS, NEBRASKA,…

The purpose of this safety manual is to provide a resource to help manage and minimize potential risks in science classrooms where students spend up to 60% of instructional time engaged in hands-on activities. This manual contains information on standards, legal aspects, and responsibilities for science safety; general laboratory safety for…
