Active learning has often been reported to improve student outcomes in STEM courses. However, there are barriers to its implementation, and it is challenging to include this approach in large classrooms with fixed seating. This investigation explores the development of a novel approach in which the class contact time was reallocated for a general…

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…

As the SARS-CoV-2 pandemic spread throughout the world, universities were faced with extraordinary challenges. Shelter-in-place orders were given, in-person classes were canceled, and at the University of California Irvine, instructors had less than 2 weeks to convert spring quarter classes from a face-to-face to an online format. A team-based…

A 3-week module incorporating the principles of green chemistry was developed for a large-enrollment, introductory organic chemistry laboratory course. An emphasis was placed on students planning their own experiments with the goal of obtaining a greener reaction (week 1). Students executed their designed experiments in week 2 and were given an…

A meta-analysis of recent quantitative studies that examine the effects of cooperative learning (CL) on achievement outcomes in chemistry is presented. Findings from 25 chemical education studies involving 3985 participants (N[subscript treatment] = 1,845; N[subscript control] = 2,140) and published since 2001 show positive association between…

The research-based pedagogical strategy of flipped classes has been shown to be effective for increasing student achievement and retention in postsecondary chemistry classes. The purpose of flipped classes is to move content delivery (e.g., lecture) outside of the classroom, freeing more face-to-face time for active learning strategies. The…

Offers tips on how to improve instructional techniques for classes with greater than 200 students. (ZWH)

Discusses the passive role that students often take in large classes and argues for teaching methods such as cooperative learning that place students in a more active learning environment. Examines the advantages and potential drawbacks of cooperative learning for large classes and provides suggestions on preparing for group work. (DDR)

This article is a general summary of the James Flack Norris Award Lecture given in November 2003. It chronicles various events leading up to the award centering on teaching chemistry to very large classes and providing information to the general public through a unique University Office for Science and Society.

Discusses a survey of selected undergraduate chemistry laboratory courses. Topics include: who preps the experiment; degree of faculty involvement; instructional loads; types of directions used; satisfaction with materials used; techniques taught; computer use; rating the laboratory; and a self rating. Provides data for each topic. (MVL)

Discusses the format of a semester course and provides details about grading, formative assessment, research papers, lecture activities, cooperative examinations, use of spreadsheets, and open-ended laboratory projects. Contains 15 references. (DDR)

Describes a sequence of five experimental courses in chemical engineering that are designed to meet the needs of students with various learning styles. The courses use a variety of teaching methods and are designed to develop and enhance creative problem-solving. (DDR)

Compares class size and faculty rating by students. Warns that certain instructors may not be effective with large class size (>100) but may be very effective with small class size. Infers that some poor large class instructors do not improve with time. (MVL)
